    Full Text Available Tumor metastasis is a complicated process with multiple steps, and liver metastasis is the most common metastatic mode of colorectal cancer. Deep understanding and study of metastatic mechanism helps to find solutions for colorectal cancer liver metastasis. Recent studies have shown that microRNA are involved in tumor metastasis and recurrence, and studies on microRNA associated with colorectal cancer liver metastasis can provide new thoughts for the development and progression, diagnosis and treatment, and prognosis of the disease. This article summarizes the research advances in microRNA associated with colorectal cancer liver metastasis and reviews the biological function and molecular mechanism of microRNA, which suggests that microRNA have a vital significance in the field of tumor metastasis, especially colorectal cancer liver metastasis.

    Liver magnetic resonance imaging (MRI) is becoming the gold standard in liver metastasis detection and treatment response assessment. The most sensitive magnetic resonance sequences are diffusion-weighted images and hepatobiliary phase images after Gd-EOB-DTPA. Peripheral ring enhancement, diffusion restriction, and hypointensity on hepatobiliary phase images are hallmarks of liver metastases. In patients with normal ultrasonography, computed tomography (CT), and positron emission tomography (PET)-CT findings and high clinical suspicion of metastasis, MRI should be performed for diagnosis of unseen metastasis. In melanoma, colon cancer, and neuroendocrine tumor metastases, MRI allows confident diagnosis of treatment-related changes in liver and enables differential diagnosis from primary liver tumors. Focal nodular hyperplasia-like nodules in patients who received platinum-based chemotherapy, hypersteatosis, and focal fat can mimic metastasis. In cancer patients with fatty liver, MRI should be preferred to CT. Although the first-line imaging for metastases is CT, MRI can be used as a problem-solving method. MRI may be used as the first-line method in patients who would undergo curative surgery or metastatectomy. Current limitation of MRI is low sensitivity for metastasis smaller than 3mm. MRI fingerprinting, glucoCEST MRI, and PET-MRI may allow simpler and more sensitive diagnosis of liver metastasis. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available The clinical and pathology features of a cow with uterine adenocarcinoma and multiple metastasis are described. Weight loss, inappetence, mild respiratory signs, and reduced milk yield were evident on clinical examination. Grossly deformed uterus, enlarged iliac lymph nodes, and rosary arranged nodules in the mesentery were felt by rectal palpation. Right side laparotomy revealed numerous small masses covering the omentum, and mesentery. Euthanasia was performed. Necropsy and histopathology exam revealed a uterine adenocarcinoma with multiple pulmonary, liver and mesentery metastasis. Uterine adenocarcinoma with metastasis should be included in the differential diagnosis of cows showing weight loss and mild respiratory distress and palpation of numerous firm nodules in the mesentery should be suggestive of neoplasias' metastasis.

    The leading cause of death among cancer patients is tumor metastasis. Tumor-derived exosomes are emerging as mediators of metastasis. In the present study, we demonstrated that exosomes play a pivotal role in the metastatic progression of colorectal cancer. First, a nude mouse model of colorectal cancer liver metastasis was established and characterized. Then, we demonstrated that exosomes from a highly liver metastatic colorectal cancer cell line (HT-29) could significantly increase the metastatic tumor burden and distribution in the mouse liver of Caco-2 colorectal cancer cells, which ordinarily exhibit poor liver metastatic potential. We further investigated the mechanisms by which HT-29-derived-exosomes influence the liver metastasis of colorectal cancer and found that mice treated with HT-29-derived exosomes had a relatively higher level of CXCR4 in the metastatic microenvironment, indicating that exosomes may promote colorectal cancer metastasis by recruiting CXCR4-expressing stromal cells to develop a permissive metastatic microenvironment. Finally, the migration of Caco-2 cells was significantly increased following treatment with HT-29-derived exosomes in vitro, further supporting a role for exosomes in modulating colorectal tumor-derived liver metastasis. The data from the present study may facilitate further translational medicine research into the prevention and treatment of colorectal cancer liver metastasis.

  6. Portal Vein Tumor Thrombus of Liver Metastasis from Lung Cancer

    Full Text Available We report a case of liver metastasis of lung carcinoma with portal vein tumor thrombus (PVTT. Although the primary lesion of lung tumor remained unchanged, the patient rapidly developed wide-spread metastases and formed PVTT of liver metastasis. The primary lesion showed features of mixed Clara and bronchial surface epithelial cell component type adenocarcinoma with small foci of micropapillary pattern. Micropapillary pattern was observed in the metastatic lesions in the liver and PVTT. Micropapillary pattern lung adenocarcinoma may develop rapid metastases and cause PVTT associated with liver metastasis. We should perform a detailed examination to establish correct diagnosis.

    One hundred and seventy cases of cancer of digestive tract were separated into three groups, advanced gastric cancer, biliary and/or pancreatic cancer and colorectal cancer. The presence of liver metastasis in each group was studied preoperatively by either liver scintigraphy or celiac and superior mesenteric angiography. In advanced gastric cancer and colorectal cancer, false negative ranged between 6.7 - 12.7 per cent by both scintigraphy and angiography. In biliary tract and/or pancreatic cancer, the ratio of false negative was significantly higher i.e. 18.8 - 22.6 per cent, which suggests the difficulty in diagnosing liver metastasis correctly in this group. The most frequent occurrences of false positive either in scintigraphy or angiography were those of masses of less than 2 cm in diameter. The difference in correct diagnosis rates for liver metastasis between scintigraphy and angiography in all three groups was only 2.9 per cent. Hence, liver scintigraphy seems to be preferable for the purpose of detecting liver metastasis prior to surgery, since further angiographical examination entails irradiation, possible complications and economic factors.

    To diagnose and explore the serological diagnostic factors for liver metastasis in patients with breast cancer before symptoms occur. A total of 430 female in-patients with breast cancer of stages 0 to IIIC who came to Tianjin Medical University Cancer Institute and Hospital from January 2003 to January 2004 were studied and followed up until May 2011. Serum levels of biochemical markers for tumor and liver were measured at the time of diagnosis. Liver metastasis was more likely to occur in patients with stage III cancer or c-erbB-2-positive expression. Alanine aminotransferase, aspartate aminotransferase, γ-glutamyltransferase (GGT), alkaline phosphatase, lactate dehydrogenase (LDH), and carbohydrate antigen 153 (CA153) levels were significantly higher in patients with liver metastasis than those without liver metastasis. Diagnostic indices of LDH, GGT, and CA153 were 174 U/L, 32 U/L, and 26.48 µg/L, respectively. The areas under the curves of LDH, GGT, and CEA were 0.795, 0.784, and 0.661, respectively, and sensitivities of parallel tests for LDH and CA153 and for GGT and CA153 were 88.6% and 85.7%, respectively. The specificity of serial tests for both pairs of enzymes was 97.7%. The sensitivity and specificity of combined tumor and biochemical markers could be used as indicators during screening for breast-liver metastasis

    In a case of esophageal cancer with liver metastases, rupture of a liver metastasis resulted in subcapsular hematoma of the liver. Digital subtraction angiography with carbon dioxide showed multiple extravasations at the surface of the liver suggesting multiple ruptures of the penetrating hepatic capsular arteries. It was suggested that these findings are not rare in cases of subcapsular hematoma; however, they have received little attention

  11. The Roles of Carcinoembryonic Antigen in Liver Metastasis and Therapeutic Approaches

    Science.gov (United States)

    2017-01-01

    Metastasis is a highly complicated and sequential process in which primary cancer spreads to secondary organic sites. Liver is a well-known metastatic organ from colorectal cancer. Carcinoembryonic antigen (CEA) is expressed in most gastrointestinal, breast, and lung cancer cells. Overexpression of CEA is closely associated with liver metastasis, which is the main cause of death from colorectal cancer. CEA is widely used as a diagnostic and prognostic tumor marker in cancer patients. It affects many steps of liver metastasis from colorectal cancer cells. CEA inhibits circulating cancer cell death. CEA also binds to heterogeneous nuclear RNA binding protein M4 (hnRNP M4), a Kupffer cell receptor protein, and activates Kupffer cells to secrete various cytokines that change the microenvironments for the survival of colorectal cancer cells in the liver. CEA also activates cell adhesion-related molecules. The close correlation between CEA and cancer has spurred the exploration of many CEA-targeted approaches as anticancer therapeutics. Understanding the detailed functions and mechanisms of CEA in liver metastasis will provide great opportunities for the improvement of anticancer approaches against colorectal cancers. In this report, the roles of CEA in liver metastasis and CEA-targeting anticancer modalities are reviewed. PMID:28588612

    Objective: To evaluate the efficacy of CT-guided percutaneous acetic acid injection (PAI) for liver metastasis. Methods: Thirty-five cases (40 lesions) with liver metastasis were treated with PAI. 4-10 ml of 30% acetic acid with 1 ml contrast media was injected into every lesion. PAI was performed twice a week, and repeated for 2 to 3 weeks. Results: The tumors shrunk in 23 lesions, and remained unchanged in 12 lesions. The efficiency was 87.5%. All cases were followed up for 3 months to 3 years. One year survival rates was 62.9% (22 cases), 2 years 40.0% (14 cases), and 3 years 22.9% (8 cases). Conclusion: PAI was an effective therapy for liver metastasis

    Enterobius vermicularis is responsible for a variety of diseases but rarely affects the liver. Accurate characterisation of suspected liver metastases is essential to avoid unnecessary surgery. In the presented case, following a diagnosis of rectal cancer, a solitary liver nodule was diagnosed as a liver metastasis due to typical radiological features and subsequently resected. At pathological assessment, however, a necrotic nodule containing E. vermicularis was identified. Solitary necrotic nodules of the liver are usually benign but misdiagnosed frequently as malignant due to radiological features. It is standard practice to diagnose colorectal liver metastases solely on radiological evidence. Without obtaining tissue prior to liver resection, misdiagnosis of solitary necrotic nodules of the liver will continue to occur.

    The aim of the present study was to establish an animal liver metastasis model with human colon cancer and investigate the inhibitory effect of the wild type (WT) p53 gene combined with thymidine kinase/ganciclovir (TK/GCV) and cytosine deaminase/5-fluorocytosine (CD/5-FC) systems on liver metastasis of colon cancer. A nude mouse liver metastasis model with human colon cancer was established via a spleen cultivation method. A total of 32 nude mice were randomly divided into four groups, each group with eight mice. Group 1 mice received splenic injections of SW480 cells (control group), while group 2 mice were injected with SW480/p53 cells in the spleen. Group 3 mice were administered splenic injections of SW480/TK-CD cells, and GCV and 5-FC were injected into the abdominal cavity. Finally, group 4 mice received splenic injections of SW480/p53 cells mixed in equal proportion with SW480/TK-CD cells, as well as GCV and 5-FC injections in the abdominal cavity. These cells described were constructed in our laboratory and other laboratories. The number of liver metastatic tumors, the liver metastasis rate, conventional pathology, electron microscopy and other indicators in the nude mice of each group were compared and observed. The nude mouse liver metastasis model with human colon cancer was successfully established; the liver metastasis rate of the control group was 100%. The results demonstrated that the rate of liver metastasis in the nude mice in each treatment group decreased, as well as the average number of liver metastatic tumors. Furthermore, the effect of the treatment group with genetic combination (group 4) was the most effective, demonstrating that WTp53 had a synergistic effect with TK/GCV and CD/5-FC. Therefore, the present study successfully established a mouse model of liver metastasis with colon cancer by injecting human colon cancer cells in the spleen. Combined gene therapy was shown to have a synergistic effect, which effectively inhibited the

    Surgery offer the only curative treatment for colorectal hepatic metastasis. Nowadays, five-year survival increases up to 58% in selected cases, due to the improvement and combination of chemotherapy, surgery and ablative treatment like embolisation, radio-frequency or cryoablation. Surgery should be integrated in a multi disciplinary approach and initial work-up must take in account patient general conditions, tumor location, and possible extra hepatic extension. Thus, a surgical resection may be performed immediately or after preparation with chemotherapy or selective portal embolization. Management of liver metastasis should be carried out in oncological hepato-biliary centre.

    To establish an effective examination system for preoperative evaluation of liver metastasis by colon cancer, we analyzed the sensitivity, cost, and efficacy of computed tomography (CT) and ultrasonography (US) in 354 patients (including 63 patients with liver metastasis). The presence or absence of liver metastasis was ultimately diagnosed 5 years after the operation. The sensitivity, specificity, and accuracy for detecting liver metastasis were 65%, 94%, and 89%, respectively for CT, 57%, 97%, and 91% for US, and 65%, 93%, and 88% for CT plus US, and there were no significant differences among them. Neither CT nor US could fully detect intrahepatic cancer spread. The cost of detection of one patient with liver metastasis was 6,298 points for plain CT, 20,169 points for enhanced CT, and 5,773 points for US. It was concluded that CT plus US should not be employed for preoperative assessment of liver metastasis, because the detection rate of the two modalities is not significantly different, and these modalities do not compensate for each other's defects. From the standpoint of the cost-benefit relationship, US should be selected for preoperative evaluation of liver metastasis. (author)

    AIM:To establish an animal model with human hepatocyte-repopulated liver for the study of liver cancer metastasis.METHODS:Cell transplantation into mouse livers was conducted using alpha-fetoprotein (AFP)-producing human gastric cancer cells (h-GCCs) and h-hepatocytes as donor cells in a transgenic mouse line expressing urokinase-type plasminogen activator (uPA) driven by the albumin enhancer/promoter crossed with a severe combined immunodeficient (SCID) mouse line (uPA/SCID mice).Host mice were divided into two groups (A and B).Group A mice were transplanted with h-GCCs alone,and group B mice were transplanted with h-GCCs and h-hepatocytes together.The replacement index (RI),which is the ratio of transplanted h-GCCs and h-hepatocytes that occupy the examined area of a histological section,was estimated by measuring h-AFP and h-albumin concentrations in sera,respectively,as well as by immunohistochemical analyses of h-AFP and human cytokeratin 18 in histological sections.RESULTS:The h-GCCs successfully engrafted,repopulated,and colonized the livers of mice in group A (RI =22.0% ± 2.6%).These mice had moderately differentiated adenocarcinomatous lesions with disrupted glandular structures,which is a characteristics feature of gastric cancers.The serum h-AFP level reached 211.0 ± 142.2 g/mL (range,7.1-324.2 g/mL).In group B mice,the h-GCCs and h-hepatocytes independently engrafted,repopulated the host liver,and developed colonies (RI =12.0% ± 6.8% and 66.0% ± 12.3%,respectively).h-GCC colonies also showed typical adenocarcinomatous glandular structures around the h-hepatocyte-colonies.These mice survived for the full 56day-study and did not exhibit any metastasis of h-GCCs in the extrahepatic regions during the observational period.The mice with an h-hepatocyte-repopulated liver possessed metastasized h-GCCs and therefore could be a useful humanized liver animal model for studying liver cancer metastasis in vivo.CONCLUSION:A novel animal model of

    Neuroendocrine tumours (NET) frequently metastasize to the liver. NET liver metastasis has been shown to respond to Yttrium-90 microspheres therapy. The aims of the present study were to define factors that predict the response to radio-embolization in patients with NET liver metastases. From January 2006 until March 2009, all patients with NET liver metastasis that received radio-embolization using TheraSphere® (glass microspheres) were reviewed. The response was determined by a change in the percentage of necrosis (ΔN%) after the first radio-embolization based on the modified RECIST criteria (mRECIST) criteria. The following confounding variables were measured: age, gender, size of the lesions, liver involvement, World Health Organization (WHO) classification, the presence of extra-hepatic metastasis, octereotide treatment and previous operative [surgery and (RFA)] and non-operative treatments (chemo-embolization and bland-embolization). In all, 25 patients were identified, with a median follow-up of 21.7 months. The median age was 64.6 years, 28% had extra-hepatic metastasis and 56% were WHO stage 2. Post-treatment, the mean ΔN% was 48.4%. Previous surgical therapy was a significant predictor of the response with a response rate of 66.7 ΔN% vs. 31.5 ΔN% (P= 0.02). Bilateral liver disease, a high percentage of liver involvement and large metastatic lesions were inversely related to the degree of tumour response although did not reach statistical significance. Radio-embolization increased the necrosis of NET liver metastasis mainly in patients with less bulky disease. This may imply that surgical therapy before radio-embolization would increase the response rates. © 2011 International Hepato-Pancreato-Biliary Association.

    Full Text Available Undetected micrometastasis plays a key role in the metastasis of cancer in colorectal cancer (CRC patients. The aim of this study is to identify a biomarker of CRC patients with liver metastasis through the detection of circulating tumor cells (CTCs. Microarray and bioinformatics analysis of 10 CRC cancer tissue specimens compared with normal adjacent tissues revealed that 31 genes were up-regulated (gene expression ratio of cancer tissue to paired normal tissue > 2 in the cancer patients. We used a weighted enzymatic chip array (WEnCA including 31 prognosis-related genes to investigate CTCs in 214 postoperative stage I–III CRC patients and to analyze the correlation between gene expression and clinico-pathological parameters. We employed the immunohistochemistry (IHC method with polyclonal mouse antibody against DVL1 to detect DVL1 expression in 60 CRC patients. CRC liver metastasis occurred in 19.16% (41/214 of the patients. Using univariate analysis and multivariate proportional hazards regression analysis, we found that DVL1 mRNA overexpression had a significant, independent predictive value for liver metastasis in CRC patients (OR: 5.764; 95% CI: 2.588–12.837; p < 0.0001 on univariate analysis; OR: 3.768; 95% CI: 1.469–9.665; p = 0.006 on multivariate analysis. IHC staining of the immunoreactivity of DVL1 showed that DVL1 was localized in the cytoplasm of CRC cells. High expression of DVL1 was observed in 55% (33/60 of CRC tumor specimens and was associated significantly with tumor depth, perineural invasion and liver metastasis status (all p < 0.05. Our experimental results demonstrated that DVL1 is significantly overexpressed in CRC patients with liver metastasis, leading us to conclude that DVL1 could be a potential prognostic and predictive marker for CRC patients.

    In the early stages of metastasis, development of the disease is dependent on growth factors produced by the host. There are clinical situations associated with an increase in these factors, such as partial resection of metastasized liver. Given the important role of hepatotrophic factors in liver regeneration, we have studied the effect of partial hepatectomy on the development of residual micrometastases in the liver, and on the neoplastic process as a whole. We used a murine model in which a rabdomiosarcoma was established by subcutaneous inoculation of syngeneic tumor cells in male Wag rats. Subsequently, the primary tumor was resected and/or a 40% hepatectomy was performed. The effect of these two surgical procedures on the tumor process was analyzed on the 25th and 35th days post-inoculation, and the percentage of regenerating hepatocytes was assessed. Both the tumorectomy and liver resection, when not combined, produced an increase in regional adenopathies without modifying the evolution of metastasis in the liver. However, when tumor excision and partial hepatectomy were performed simultaneously, there was a net increase in the metastatic process. In addition to a rapid spread of the disease (lung, mediastinum, retroperitoneum), the number of liver metastases increased by 300%. This development coincided with a steep rise in the percentage of regenerating hepatocytes, which nearly doubled that of the group subjected only to liver resection. We conclude that liver resection, alone or combined with excision of the primary tumor, may enhance tumor progression, both locally and at the metastasic level.

  2. Multiple Beneficial Health Effects of Natural Alkylglycerols from Shark Liver Oil

    2010-07-01

    Full Text Available Alkylglycerols (alkyl-Gro are ether lipids abundant in the liver of some elasmobranch fish species such as ratfishes and some sharks. Shark liver oil from Centrophorus squamosus (SLO, or alkyl-Gro mix from this source, have several in vivo biological activities including stimulation of hematopoiesis and immunological defences, sperm quality improvement, or anti-tumor and anti-metastasis activities. Several mechanisms are suggested for these multiple activities, resulting from incorporation of alkyl-Gro into membrane phospholipids, and lipid signaling interactions. Natural alkyl-Gro mix from SLO contains several alkyl-Gro, varying by chain length and unsaturation. Six prominent constituents of natural alkyl-Gro mix, namely 12:0, 14:0, 16:0, 18:0, 16:1 n-7, and 18:1 n-9 alkyl-Gro, were synthesized and tested for anti-tumor and anti-metastatic activities on a model of grafted tumor in mice (3LL cells. 16:1 and 18:1 alkyl-Gro showed strong activity in reducing lung metastasis number, while saturated alkyl-Gro had weaker (16:0 or no (12:0, 14:0, 18:0 effect. Multiple compounds and mechanisms are probably involved in the multiple activities of natural alkyl-Gro.

    Recent reports suggested that phosphatase of regenerating liver (PRL)-3 might be involved in colorectal carcinoma metastasis with an unknown mechanism. Here we demonstrated that PRL-3 expression was up-regulated in human liver carcinoma compared with normal liver. PRL-3 was also highly expressed in metastatic melanoma B16-BL6 cells but not in its lowly metastatic parental cell line, B16 cells. B16 cells transfected with PRL-3 cDNA displayed morphological transformation from epithelial-like shape to fibroblast-like shape. PRL-3-overexpressed cells showed much higher migratory ability, which could be reversed by specific anti-sense oligodeoxynucleotide and the phosphatase inhibitors sodium orthovanadate or potassium bisperoxo oxovanadate V. Meanwhile, the expression of the catalytically inactive PRL-3 mutations (D72A or C104S) significantly reduced the cell migratory capability. In addition, PRL-3 transfectants demonstrated altered extracellular matrix adhesive property and up-regulated integrin-mediated cell spreading efficiency. Furthermore, we confirmed that PRL-3 could facilitate lung and liver metastasis of B16 cells in an experimental metastasis model in mice, consistent with accelerated proliferation and growth rate both in vitro and in vivo. Together, these observations provide convincing evidence that PRL-3 truly plays a causal role in tumor metastasis. PMID:15161639

    Fatty liver disease is increasing in the developed and developing world. Liver metastasis from malignant lymphoma in the fatty liver is poorly understood. In a previous report, we developed color-coded imaging of the tumor microenvironment (TME) of the murine EL4-RFP malignant lymphoma during metastasis, including the lung. In the present report, we investigated the potential and microenvironment of the fatty liver induced by a choline-deficient diet as a metastatic site in this mouse lymphoma model. C57BL/6-GFP transgenic mice were fed with a choline-deficient diet in order to establish a fatty liver model. EL4-RFP cells were injected in the spleen of normal mice and fatty-liver mice. Metastases in mice with fatty liver or normal liver were imaged with the Olympus SZX7 microscope and the Olympus FV1000 confocal microscope. Metastases of EL4-RFP were observed in the liver, ascites and bone marrow. Primary tumors were imaged in the spleen at the injection site. The fewest metastases were observed in the fatty liver. In addition, the fewest cancer-associated fibroblasts (CAFs) were observed in the fatty liver. The relative metastatic resistance of the fatty liver may be due to the reduced number of CAFs in the fatty livers. The mechanism of the effect of the choline-deficient diet is discussed.

    A 70-year-old man with distal bile duct carcinoma underwent a subtotal stomach-preserving pancreaticoduodenectomy without adjuvant chemotherapy. One and a half years after the surgery, elevated levels of serum SPan-1(38.1 U/mL)were observed and CT scans demonstrated a solitary metastasis, 25mm in size, in segment 8 of the liver. The patient received 2 courses of gemcitabine-cisplatin combination chemotherapy. No new lesions were detected after chemotherapy and the patient underwent a partial liver resection of segment 8. The pathological examination revealed a metachronous distant metastasis originating from the bile duct carcinoma. Subsequently, the patient received S-1 adjuvant chemotherapy for 6 months. Following completion of all therapies, the patient survived without tumor recurrence for 3 years and 10 months after the initial operation. Thus, surgical interventions might be effective in improving prognosis among selected patients with postoperative liver metastasis of bile duct carcinoma.

    Full Text Available Future liver remnant (FLR is the most important deciding factor in planning for liver resection. Portal vein embolization (PVE was first introduced in the 1980s to induce liver hypertrophy, enabling removal of multiple/bilobar tumors. PVE was later combined with sequential hepatectomies with the aim of allowing the liver remnant to hypertrophy (15–20% between procedures. However, the interval between the two procedures (3–8 weeks put patients at risk for disease progression. With portal vein ligation alone or when combined with sequential hepatectomy, there is also a risk for inadequate liver hypertrophy because of intrahepatic portal collaterals leading to a high (19–30% dropout rate. The ALPPS procedure (associating liver partition and portal vein ligation for staged hepatectomy was recently developed as a feasible means to perform extensive/bilobar liver resections. It produces rapid, enormous hypertrophy of the remnant, making previously unresectable lesions resectable. Indications for ALPPS include any extensive liver resection with inadequate FLR. Here we present a novel indication for ALPPS as a rescue when inadequate FLR was faced intraoperatively, during a simultaneous resection of rectal primary and liver metastasis.

    Objective: To observe the therapeutic effect of angiogenesis inhibitor combined with radiotherapy on liver metastasis model of colon cancer. Methods: Nude mice liver metastasis model of colon cancer was established with human colon cancer cells line (LS174T) inoculated into mice' spleen and followed by splenectomy. Angiogenesis inhibitor 2-ME and radiotherapy were administered after-wads. The growth inhibition effect on metastases and neovessel was examined. Results: The incidences of liver metastasis were 100% in this intrasplenic injection model. The mean weight and microvessel density 4 weeks after inoculation were 53.6 ± 4.7 mg, 8.4 ± 1.7 in treatment group as compared to 173.9 ± 11.6 mg, 41.2 ± 6.3 in control group respectively. Conclusion: 2-ME combined with radiotherapy has significant inhibition on the growth of liver metastases. Angiogenesis inhibition is one of the mechanisms of its efficiency. (authors)

    We present two cases of solitary necrotic nodules of the liver which on radiologic images mimicked hepatic metastasis. Solitary necrotic nodule of the liver is a rare but benign entity which histopathologically consists of an outer fibrotic capsule with inflammatory cells and a central core of amorphous necrotic material. The lesion was seen on contrast-enhanced CT as an ovoid-shaped hypoattenuating nodule; on CT during hepatic arteriography as enhancing nodule; on intraoperative US as a target-appearing hypoechoic nodule; on T2WI as a hyperintensity nodule, and on dynamic MR as a subtle peripheral enhancing nodule. Although the radiologic features are not specific, solitary necrotic nodule of the liver should be included in the differential diagnosis of hepatic metastasis.

    We report a case of chemotherapy with FOLFOXIRI plus cetuximab for liver metastasis of sigmoid colon cancer. The patient was a 40's man who was diagnosed with sigmoid colon cancer with liver metastasis. Colonoscopy revealed a type 2 tumor with stenosis in the sigmoid colon. He underwent sigmoidectomy under laparotomy, and after the operation, received 7 courses of chemotherapy with FOLFOXIRI plus cetuximab. The liver tumor was sufficiently reduced, and laparotomy and liver right lobectomy were performed. Histopathology revealed a modified, Grade 2 tumor regression. He has been followed for 1 year 4months after the operation.

    Full Text Available We present here the rare clinical case of a 44-year-old gentleman with metastasis from colon carcinoma to the esophagus presenting with multiple nodules and dysphagia, which was successfully managed with systemic chemotherapy. The patient presented at our institution with 3-month history of dysphagia almost 4 years after being operated for stage III carcinoma in the sigmoid colon. Endoscopic findings showed multiple nodules at the gastroesophageal junction and mid esophagus. Histological features and immunostains confirmed the diagnosis of metastatic colon carcinoma. Because of evidence of extensive metastatic disease in the spine and liver requiring systemic therapy, the patient was treated with chemotherapy with irinotecan and cetuximab, with subsequent improvement in tumor markers, liver metastasis and symptoms of dysphagia. Even though repeat endoscopy showed no improvement in esophageal nodules, the overall response to chemotherapy was positive. In conclusion, we present a very rare, previously unreported case of metastases from colon cancer to the esophagus presenting as non-obstructive nodules and dysphagia that responded to systemic chemotherapy.

    Objective: To study the significance of CD44 and CD54 expression in animal models with liver metastasis of colorectal cancer and try to find a stable biological marker for the early diagnosis of liver metastasis of colorectal cancer. Methods: Fourth two nude mice of 4-6 wks were adopted in the study. Thirty-six were used to establish animal models with liver metastasis of colorectal cancer, the rest 6 mice were used as the controls. 36 mice of the experimental group were divided into 6 subgroups, each containing 6 mice, in which low grade colorectal adenocarcinoma cells were injected in the subcapsule of the spleen. On the day 10th, 15th, 20th, 25th, 30th day and at the time of the brink of death, animas in each subgroup were sacrificed by eyeball removal and blood letting. Serum CD44, CD54 and CEA levels of the nude mice were measured by ELISA and the sizes and number of liver metastatic loci were observed and noted. the 6 mice for control were raised in the same cages and were killed on the 30th day, and were compared with that in the experimental group. Results: Through the measurement at different phrases, authors found with the development progression and metastasis of cancer, CD44 and CD54 levels in the animal serum tend to increase gradually and were correlated positively with the growth time, size, and extent metastasis of the cancer. Conclusion: CD44 and CD54 may be early tumor markers for liver metastasis of colorectal cancer

    The investigation of the predictors of outcome after hepatic resection for solitary colorectal liver metastasis. We recruited 350 patients with solitary colorectal liver metastasis at the University Hospitals of Jena and Magdeburg, who underwent curative liver resection between 1993 and 2014. All patients had follow-up until death or till summer 2016. The follow-up data concern 96.6% of observed patients. The 5- and 10-year overall survival rates were 47 and 28%, respectively. The 5- and 10-year disease-free survival rates were 30 and 20%, respectively. The analysis of the prognostic factors revealed that the pT category of primary tumour, size and grade of the metastasis and extension of the liver resection had no statistically significant impact on survival and recurrence rates. In multivariate analysis, age, status of lymph node metastasis at the primary tumour, location of primary tumour, time of appearance of the metastasis, the use of preoperative chemotherapy and the presence of extrahepatic tumour proved to be independent statistically significant predictors for the prognosis. Moreover, patients with rectal cancer had a lower intrahepatic recurrence rate, but a higher extrahepatic recurrence rate. The long-term follow-up of patients with R0-resected liver metastasis is multifactorially influenced. Age and comorbidity have a role only in the overall survival. More than three lymph node metastasis reduced both the overall and disease-free survival. Extrahepatic tumour had a negative influence on the extrahepatic recurrence and on the overall survival. Neither overall survival nor recurrence rates was improved using neoadjuvant chemotherapy.

    Isolated macro-nodular liver tuberculosis is a very rare condition. It may mimic primitive or secondary tumors of the liver. This could delay or mislead the therapeutic management. An immunocompetent 48-year-old man with a history of non-metastatic seminoma was treated with right orchidectomy followed by 20 Gy radiotherapy. The discovery, 8 months later, of a 2 cm nodule of the hepatic dome evoked a liver metastasis. Percutaneous biopsy was not feasible. Wedge resection was performed whereas medical treatment would have sufficed, as pathologic examination of the resected specimen showed a macro-nodular hepatic tuberculosis. The patient received anti-tuberculosis drugs for 9 months. The diagnosis of isolated macro-nodular liver tuberculosis is frequently misleading, particularly in immunocompetent and paucisymptomatic patients. Thus percutaneous biopsy is mandatory for diagnosis and also prior to any major surgeries. © 2018 The Author(s).

    The antitumor properties of bacteria have been demonstrated over the past decades. However, the efficacy is limited and unclear. Furthermore, systemic infection remains a serious concern in bacteria treatment. In this study, the effect of YB1, a rationally designed 'obligate' anaerobic Salmonella typhimurium strain, on liver tumor growth and metastasis in a nude mouse orthotopic liver tumor model was investigated. The orthotopic liver tumor model was established in nude mice using the hepatocellular carcinoma cell line MHCC-97L. Two weeks after orthotopic liver tumor implantation, YB1, SL7207 and saline were respectively administered through the tail vein of the mice. Longitudinal monitoring of tumor growth and metastasis was performed using Xenogen IVIS, and direct measurements of tumor volume were taken 3 weeks after treatment. In vitro , MHCC-97L and PLC cells were incubated with YB1 or SL7207 under anaerobic conditions. YB1 was observed to invade tumor cells and induce tumor cell apoptosis and death. The results revealed that all mice in the YB1 group were alive 3 weeks after YB1 injection while all mice in the SL7207 group died within 11 days of the SL7207 injection. The body weight decreased by ~9% on day 1 after YB1 injection and but subsequently recovered. Liver tumor growth and metastases were significantly inhibited following YB1 treatment. By contrast to the control group, a large number of Gr1-positive cells were detected on days 1 to 21 following YB1 treatment. Furthermore, YB1 also effectively invaded tumor cells and induced tumor cell apoptosis and death. In conclusion, YB1 suppressed liver tumor growth and metastasis in a nude mice liver tumor model. The potential mechanism may be through enhancing innate immune response and inducing tumor cell apoptosis and cell death.

    The present study was performed to clarify the clinical characteristics of brain metastasis from colorectal cancer. Five patients with brain metastasis from colorectal cancer treated at our institute between 2001 and 2005 were included in the study. Clinical findings and survival time were determined and an appropriate system for follow-up in such cases was considered. Brain metastasis was found after surgery for colorectal cancer in 4 cases. In addition, colorectal cancer was found after diagnosis of brain metastasis in 1 case. At the time of diagnosis of brain metastasis, all patients had lung metastasis and 3 had liver metastasis. The mean periods between surgery for colorectal cancer and lung and brain metastases were 19.5 and 38.2 months, respectively. In all cases, brain metastasis was diagnosed by imaging after the appearance of neurological symptoms. Brain metastases were multiple in 1 case and focal in 4 cases. We performed gamma knife radiation therapy, and the symptoms disappeared or decreased in all cases. Mean survival time after brain metastasis was 3.0 months. Prognosis after brain metastasis is poor, but gamma knife radiation therapy contributed to patients' quality of life. (author)

    Metastasis of malignant tumors to the kidney is clinically rare and often discovered by autopsy. Primary lymphoma and lung cancer are known that can metastasize to the kidney. Other malignant tumor metastasis to the kidney is very unusual. Primary cervical cancer metastasis to adjacent pelvic organs and lymph nodes are well known followed by abdominal solid organs such as the liver and adrenal glands. However, reported primary cervical cancer metastasis to the kidney is extremely rare and mostly appeared as bilateral multiple renal masses. We report here on a rare case of unilateral single renal metastasis from primary cervical cancer after concur- rent chemoradiotherapy.

    A 68-year-old man diagnosed with cT3N2 adenocarcinoma of the rectum presented with a synchronous solitary liver metastasis on CT scan. Neoadjuvant chemoradiotherapy was started to downstage the primary tumour. Resection of the rectal tumour followed 3 months after the last radiotherapy session and primary resection of the isolated liver lesion was performed in the intervening period. Histopathological assessment of the liver lesion, however, showed no malignancy, but did reveal a necrotic infection due to Enterobius vermicularis. This parasite is frequently found in the intestines, but only rarely infects the liver. The patient was subsequently treated with the anthelmintic drug mebendazole 100 mg once a week for 2 weeks. Histopathological assessment of the rectal specimen showed complete regression after neoadjuvant chemoradiotherapy without evidence of remaining E. vermicularis, suggesting pinworm eradication. The patient recovered promptly after both surgical procedures. PMID:26546623

    Liver metastasis is an important prognostic factor in colorectal cancer. The efficacy of resection of metastatic lesions in liver metastasis of colorectal cancer is also widely recognized. However, studies on treatment methods of unresectable cases have not been sufficient and obtaining complete remission (CR) for liver metastasis is rare with chemotherapy. Selection of reliable chemotherapy for unresectable liver metastasis is an urgent necessity. The usefulness of oxaliplatin, 5-flurouracil and leucovorin combination therapy (FOLFOX) has recently been reported, but CR of liver metastasis is rare. The current status and new therapeutic significance of FOLFOX therapy are discussed based on the literature of colorectal cancer chemotherapy to date, and the clinical experience in which we obtained CR for liver metastasis is reported. The patient had stage IV rectal cancer, perforative peritonitis, pelvic abscess and simultaneous multiple liver metastasis. The patient underwent an emergency operation using the Hartmann's procedure. Liver metastasis is considered to be a prognostic factor and FOLFOX was selected as the postoperative chemotherapy, CR of the liver metastasis was obtained. FOLFOX was suggested to have new clinical significance in oncologic emergencies against unresectable liver metastasis in colorectal cancer and should serve as adjuvant chemotherapy that will contribute to improvement of treatment results.

    PurposeTo assess whether fusion imaging-guided percutaneous microwave ablation (MWA) can improve visibility and targeting of liver metastasis that were deemed inconspicuous on ultrasound (US).Materials and MethodsMWA of liver metastasis not judged conspicuous enough on US was performed under CT/US fusion imaging guidance. The conspicuity before and after the fusion imaging was graded on a five-point scale, and significance was assessed by Wilcoxon test. Technical success, procedure time, and procedure-related complications were evaluated.ResultsA total of 35 patients with 40 liver metastases (mean size 1.3 ± 0.4 cm) were enrolled. Image fusion improved conspicuity sufficiently to allow fusion-targeted MWA in 33 patients. The time required for image fusion processing and tumors’ identification averaged 10 ± 2.1 min (range 5–14). Initial conspicuity on US by inclusion criteria was 1.2 ± 0.4 (range 0–2), while conspicuity after localization on fusion imaging was 3.5 ± 1 (range 1–5, p < 0.001). Technical success rate was 83% (33/40) in intention-to-treat analysis and 100% in analysis of treated tumors. There were no major procedure-related complications.ConclusionsFusion imaging broadens the scope of US-guided MWA to metastasis lacking adequate conspicuity on conventional US. Fusion imaging is an effective tool to increase the conspicuity of liver metastases that were initially deemed non visualizable on conventional US imaging.

    It has previously been reported that magnolol, a phenolic compound isolated from Magnolia obovata, inhibited tumour cell invasion in vitro. The purpose of this study was to investigate the antimetastatic effect of magnolol on tumour metastasis in vivo with experimental and spontaneous metastasis models and to clarify the mechanism. The antimetastatic effects of magnolol were evaluated by an experimental liver and spleen metastasis model using L5178Y-ML25 lymphoma, or an experimental and spontaneous lung metastasis model using B16-BL6 melanoma. Intraperitoneal (i.p.) administration of 2 or 10 mg/kg of magnolol significantly suppressed liver and spleen metastasis or lung metastasis. As for the spontaneous lung metastasis model using B16-BL6 melanoma, multiple i.p. administrations of 10 mg/kg of magnolol after and before tumour inoculation significantly suppressed lung metastasis and primary tumour growth. In addition, magnolol significantly inhibited B16-BL6 cell invasion of the reconstituted basement membrane (Matrigel, MG) without affecting cell growth. These data from the in vivo experiments suggest that magnolol possesses strong antimetastatic ability and that it may be a lead compound for drug development. The antimetastatic action of magnolol is considered to be due to its ability to inhibit tumour cell invasion. Copyright 2003 John Wiley & Sons, Ltd.

    A 61-year-old man had a F-18 FDG PET/CT scan for evaluation of a common bile duct cancer identified on CT. The PET/CT image showed a hypermetabolic mass in the common bile duct, and a focal area of increased F-18 FDG uptake in segment IV of the liver, which corresponded to a hypoattenuated lesion on non-enhanced CT, and was consistent with hepatic metastasis. The patient underwent choledochojejunostomy with hepatic resection, and pathologic findings were compatible with an eosinophilic abscess in the liver. This case demonstrates that F-18 FDG uptake by an eosinophilic abscess can mimic hepatic metastasis in a patient with a malignancy

    Full Text Available Hepatocellular carcinoma (HCC is still a prevalent gastrointestinal cancer. Liver transplantation (LT is one of the main means in the comprehensive treatment of HCC because it radically removes the tumor. However, tumor recurrence and metastasis after LT remain the main obstacles to long-term survival. In recent years, substantial progress has been made in the diagnosis and treatment of HCC thanks to the technological improvement and experience accumulation worldwide. The HCC indications for LT, prediction of HCC recurrence and metastasis, perioperative management in LT, and comprehensive treatment of recurrent HCC after LT are reviewed.

    Objective: To probe the blood supply of liver metastasis by celiac artery, proper hepatic artery DSA, portal vein perfusion CT during superior mesenteric arterial portography (PCTAP). Methods: One hundred patients with liver metastases were examined prospectively by plain CT scan, multiphase enhanced CT scan, celiac arteriography and proper hepatic arteriography. Of them, 56 patients were examined by PCTAP. All primary lesions were confirmed by operation and (or) pathology examination. In order to investigate the blood supply of metastasis lesions, the software of Photoshop was used to obtain the time-attenuation curves (TDC) of tumor center, tumor edge, portal vein and normal liver parenchyma adjacent to the tumor to calculate liver perfusion for DSA image analysis, while a deconvolution model from CT perfusion software was designed for the dual blood supply. Results: DSA findings: TDC of proper hepatic arteriography showed: the mean peak concentration (K value) in tumor centers was (67 ± 12)%, and it was (76 ± 15)% for peritumor tissue, (51 ± 10)% in normal liver parenchyma. TDC of celiac arteriogaphy showed that the contrast concentration of tumor centers and tumor edge increased fast in early stage, then maintained a slight upward plateau, in the meanwhile, the contrast concentration of normal liver parenchyma kept increasing slowly. PCTAP findings: tumors exhibited no enhancement during 30 s continued scans. Conclusion: The blood supply of liver metastasis mainly comes from hepatic artery, but barely from portal vein. (authors)

  10. Molecular signatures associated with HCV-induced hepatocellular carcinoma and liver metastasis.

    Directory of Open Access Journals (Sweden)

    Valeria De Giorgi

    Full Text Available Hepatocellular carcinomas (HCCs are a heterogeneous group of tumors that differ in risk factors and genetic alterations. In Italy, particularly Southern Italy, chronic hepatitis C virus (HCV infection represents the main cause of HCC. Using high-density oligoarrays, we identified consistent differences in gene-expression between HCC and normal liver tissue. Expression patterns in HCC were also readily distinguishable from those associated with liver metastases. To characterize molecular events relevant to hepatocarcinogenesis and identify biomarkers for early HCC detection, gene expression profiling of 71 liver biopsies from HCV-related primary HCC and corresponding HCV-positive non-HCC hepatic tissue, as well as gastrointestinal liver metastases paired with the apparently normal peri-tumoral liver tissue, were compared to 6 liver biopsies from healthy individuals. Characteristic gene signatures were identified when normal tissue was compared with HCV-related primary HCC, corresponding HCV-positive non-HCC as well as gastrointestinal liver metastases. Pathway analysis classified the cellular and biological functions of the genes differentially expressed as related to regulation of gene expression and post-translational modification in HCV-related primary HCC; cellular Growth and Proliferation, and Cell-To-Cell Signaling and Interaction in HCV-related non HCC samples; Cellular Growth and Proliferation and Cell Cycle in metastasis. Also characteristic gene signatures were identified of HCV-HCC progression for early HCC diagnosis.A diagnostic molecular signature complementing conventional pathologic assessment was identified.

    Homing of colorectal cancer (CRC) cells to the liver is a non-random process driven by a crosstalk between tumour cells and components of the host tissue. Here we report the isolation of a liver metastasis-specific peptide ligand (CGIYRLRSC) that binds a complex of E-cadherin and α(6) integrin on the surface of CRC cells. We identify angiopoietin-like 6 protein as a peptide-mimicked natural ligand enriched in hepatic blood vessels of CRC patients. We demonstrate that an interaction between hepatic angiopoietin-like 6 and tumoural α(6) integrin/E-cadherin drives liver homing and colonization by CRC cells, and that CGIYRLRSC inhibits liver metastasis through interference with this ligand/receptor system. Our results indicate a mechanism for metastasis whereby a soluble factor accumulated in normal vessels functions as a specific ligand for circulating cancer cells. Consistently, we show that high amounts of coexpressed α(6) integrin and E-cadherin in primary tumours represent a poor prognostic factor for patients with advanced CRC. Copyright © 2012 The Authors.

    c-Jun/AP-1 has been linked to invasive properties of aggressive breast cancer. Recently, it has been reported that overexpression of c-Jun in breast cancer cell line MCF-7 resulted in increased AP-1 activity, motility and invasiveness of the cells in vitro and tumor formation in nude mice. However, the role of c-Jun in metastasis of human breast cancer in vivo is currently unknown. To further investigate the direct involvement of c-Jun in tumorigenesis and metastasis, in the present study, the effects of c-Jun overexpression were studied in both in vitro and in nude mice. Ectopic overexpression of c-Jun promoted the growth of MCF-7 cells and resulted in a significant increase in the percentage of cells in S phase and increased motility and invasiveness. Introduction of c-Jun gene alone into weakly invasive MCF-7 cells resulted in the transfected cells capable of metastasizing to the nude mouse liver following tail vein injection. The present study confirms that overexpression of c-Jun contributes to a more invasive phenotype in MCF-7 cells. It indicates an interesting relationship between c-Jun expression and increased property of adhesion, migration and in vivo liver metastasis of MCF-7/c-Jun cells. The results provide further evidence that c-Jun is involved in the metastasis of breast cancer. The finding also opens an opportunity for development of anti-c-Jun strategies in breast cancer therapy

    To evaluate the usefulness of transcatheter arterial chemoembolization (TACE) in the management of gastrointestinal leiomyosarcoma metastatic to the liver. Ten patients with gastrointestinal leiomyosarcoma and hepatic metastasis underwent TACE after surgical resection of the primary tumor. All of the leiomyosarcomas originated from the stomach(n=3D5), duodenum (n=3D1) or jejunum(n=3D4), and the interval between primary tumor resection and hepatic metastasis was 1-120(mean 26) months. Using an emulsion of 3-20mL of Lipiodol and 15-60mg of doxorubicin. TACE was performed, and in five patients, gelfoam embolization was added. Therapeutic response was evaluated by follow-up CT, and nine patients underwent repeated TACE (range:2-9 times;interval:1-9 months). On celiac arteriography, all cases showed hypervascular tumor staining. As an initial therapeutic response based on CT assessment, more than 50% regression of the tumor (partial remission) was achieved in seven patients, and in the remaining three, regression was 20-30%(stable disease); neither complete remission nor progression was seen. With regard to long-term survival, five patients died at 5, 8, 14, 20 and 49 (median, 19) months after initial TACE. The remaining five, in whom follow-up has extended for 13-54 months, are still alive. Overall, survival time ranged from 5-54(median, 19) months, and except for postembolization syndrome, there was no specific complication. The period of durable tumor regression before progression ranged from 6 to 54 (median, 17) months. TACE can be a safe and effective method for the palliation of gastrointestinal leiomyosarcoma metastatic to the liver.=20.

    The mainstay of treatment for metastatic colorectal cancer is surgery. Therefore, colorectal cancer metastasis is distinctive, compared to other cancer types in which chemotherapy is the main treatment. Initially, Japan experienced medical druglag compared with western countries. However, the use of oxaliplatin for unresectable recurrent metastatic colorectal cancer became available in Japan, as well as in western countries, in 2005. We have since shifted chemotherapeutic regimens from monotherapy to combination therapy with molecular targeted agents. The combination therapy has rapidly become a standard therapy for unresectable metastatic colorectal cancer, and prognosis has dramatically increased for patients with this condition. Herein, we describe the treatment of liver metastasis of colorectal cancer, and surgery and adjuvant or neoadjuvant therapy options for resectable cancer. Furthermore, we focus on conversion therapy for unresectable cancer.

    Ever since Stephen Paget's 1889 hypothesis, metastatic organotropism has remained one of cancer's greatest mysteries. Here we demonstrate that exosomes from mouse and human lung-, liver- and brain-tropic tumour cells fuse preferentially with resident cells at their predicted destination, namely lung fibroblasts and epithelial cells, liver Kupffer cells and brain endothelial cells. We show that tumour-derived exosomes uptaken by organ-specific cells prepare the pre-metastatic niche. Treatment with exosomes from lung-tropic models redirected the metastasis of bone-tropic tumour cells. Exosome proteomics revealed distinct integrin expression patterns, in which the exosomal integrins α6β4 and α6β1 were associated with lung metastasis, while exosomal integrin αvβ5 was linked to liver metastasis. Targeting the integrins α6β4 and αvβ5 decreased exosome uptake, as well as lung and liver metastasis, respectively. We demonstrate that exosome integrin uptake by resident cells activates Src phosphorylation and pro-inflammatory S100 gene expression. Finally, our clinical data indicate that exosomal integrins could be used to predict organ-specific metastasis.

    Thyroid cancer is usually, relatively hypofunctional; most patients with thyroid cancer are clinically euthyroid. The combination of thyroid cancer and thyrotoxicosis is not common. We herein, report a case of follicular thyroid cancer with hyperfunctioning metastasis in a 43-year-old woman who presented with thyrotoxicosis, a cold right thyroid nodule, and low I-131 uptake at the thyroid bed. An additional total body scan with I-131 revealed a large radioiodine avid osteolytic bone metastasis with soft tissue masses and liver metastasis. The patient received treatment with total thyroidectomy, methimazole, and I-131 at a cumulative dose of 600 mCi along with recombinant human thyroid-stimulating hormone before the first I-131 treatment and palliative radiation. The patient had normal liver function test and experienced a mild degree of bone marrow suppression after I-131. At the 2-year follow-up, the patient was still alive with the progression of bone metastases but was doing well with less severe thyrotoxicosis, good ambulation, and an Eastern Cooperative Oncology Group performance status of 2. Clinicians should be aware of the unusual concurrent presentation of thyrotoxicosis and thyroid cancer, a differential diagnosis in patients with thyrotoxicosis and low or normal radioiodine uptake over the neck and also potential pitfalls during radionuclide treatment

    Full Text Available Fluorescence-guided surgery (FGS of cancer is an area of intense development. In the present report, we demonstrate that the telomerase-dependent green fluorescent protein (GFP-containing adenovirus OBP-401 could label colon-cancer liver metastasis in situ in an orthotopic mouse model enabling successful FGS. OBP-401-GFP-labeled liver metastasis resulted in complete resection with FGS, in contrast, conventional bright-light surgery (BLS did not result in complete resection of the metastasis. OBP-401-FGS reduced the recurrence rate and prolonged over-all survival compared with BLS. In conclusion, adenovirus OBP-401 is a powerful tool to label liver metastasis in situ with GFP which enables its complete resection, not possible with conventional BLS.

  20. Control of Both Myeloid Cell Infiltration and Angiogenesis by CCR1 Promotes Liver Cancer Metastasis Development in Mice

    2013-06-01

    Full Text Available Expression of the CC chemokine receptor 1 (CCR1 by tumor cells has been associated with protumoral activity; however, its role in nontumoral cells during tumor development remains elusive. Here, we investigated the role of CCR1 deletion on stromal and hematopoietic cells in a liver metastasis tumor model. Metastasis development was strongly impaired in CCR1-deficient mice compared to control mice and was associated with reduced liver monocyte infiltration. To decipher the role of myeloid cells, sublethally irradiated mice were reconstituted with CCR1-deficient bone marrow (BM and showed better survival rates than the control reconstituted mice. These results point toward the involvement of CCR1 myeloid cell infiltration in the promotion of tumor burden. In addition, survival rates were extended in CCR1-deficient mice receiving either control or CCR1-deficient BM, indicating that host CCR1 expression on nonhematopoietic cells also supports tumor growth. Finally, we found defective tumor-induced neoangiogenesis (in vitro and in vivo in CCR1-deficient mice. Overall, our results indicate that CCR1 expression by both hematopoietic and nonhematopoietic cells favors tumor aggressiveness. We propose CCR1 as a potential therapeutical target for liver metastasis therapy.

    Background & Aims : Primary tumors of colorectal carcinoma (CRC) with liver metastasis might gain some liver-specific characteristics to adapt the liver micro-environment. This study aims to reveal potential liver-like transcriptional characteristics associated with the liver metastasis in primary colorectal carcinoma. Methods: Among the genes up-regulated in normal liver tissues versus normal colorectal tissues, we identified "liver-specific" genes whose expression levels ranked among the bottom 10% ("unexpressed") of all measured genes in both normal colorectal tissues and primary colorectal tumors without metastasis. These liver-specific genes were investigated for their expressions in both the primary tumors and the corresponding liver metastases of seven primary CRC patients with liver metastasis using microdissected samples. Results: Among the 3958 genes detected to be up-regulated in normal liver tissues versus normal colorectal tissues, we identified 12 liver-specific genes and found two of them, ANGPTL3 and CFHR5 , were unexpressed in microdissected primary colorectal tumors without metastasis but expressed in both microdissected liver metastases and corresponding primary colorectal tumors (Fisher's exact test, P colorectal tumors may express some liver-specific genes which may help the tumor cells adapt the liver micro-environment.

    Colorectal cancer is a common cancer and a leading cause of cancer-related death worldwide. The liver is a dominant metastatic site for patients with colorectal cancer. Molecular mechanisms that allow colorectal cancer cells to form liver metastases are largely unknown. Activation of epithelial-mesenchymal transition is the key step for metastasis of cancer cells. We recently reported that dual-specificity tyrosine-regulated kinase 2 (DYRK2) controls epithelial-mesenchymal transition in breast cancer and ovarian serous adenocarcinoma. The aim of this study is to clarify whether DYRK2 regulates liver metastases of colorectal cancer. We show that the ability of cell invasion and migration was abrogated in DYRK2-overexpressing cells. In an in vivo xenograft model, liver metastatic lesions were markedly diminished by ectopic expression of DYRK2. Furthermore, we found that patients whose liver metastases expressed low DYRK2 levels had significantly worse overall and disease-free survival. Given the findings that DYRK2 regulates cancer cell metastasis, we concluded that the expression status of DYRK2 could be a predictive marker for liver metastases of colorectal cancer. © 2017 The Authors.

    We present a case of a patient with stage IIIC metastatic seminoma with a persistent chemorefractory liver lesion. The patient was deemed a poor surgical candidate due to the tumor’s aggressive biology with numerous other liver lesions treated with chemotherapy and a relatively high probability for additional recurrences. Further chemotherapy with curative intent was not a feasible option due to the fact that the patient had already received second-line high-dose chemotherapy and four cycles of third-line treatment complicated by renal failure, refractory thrombocytopenia, and debilitating neuropathy. After initial failure of laser, microwave ablation of the chemorefractory liver metastasis resulted in prolonged local tumor control and rendered the patient disease-free for more than 35 months, allowing him to regain an improved quality of life.

    Objective: To investigate the effect of interventional treatment with p53 on the invasion and metastasis of VX2 liver tumor in experimental rabbits. Methods: VX2 carcinoma cells were surgically implanted into the left hepatic lobe in 48 New Zealand white rabbits, and the rabbit hepatic carcinoma models were thus established. The rabbits were randomly divided into 4 groups with 12 rabbits in each group. After hepatic arterial catheterization was completed physiological saline (control group), Lipiodol (Group A), Ad-p53 (Group B) and Lipiodol+Ad-p53 (Group C) were respectively infused into the rabbits of four groups via common hepatic artery. One week after the procedure the rabbits were sacrificed and the livers were removed for the determination of matrix metalloprotein-2 (MMP-2), proliferating cell nuclear antigen (PCNA) and vascular endothelial growth factor (VEGF) of the tumor with immunohistochemistry technique. Results: The tumor growth in study groups (group A, B and C) was markedly suppressed, which was significantly different in comparison with that in control group (P 0.05). The positive rates of MMP-2, PCNA and VEGF in group B and C were significantly lower than those in control group (P < 0.05). The positive rates of MMP-2, PCNA and VEGF of the rabbits with metastasis were markedly higher than those without metastasis(P < 0.05). MMP-2 bore a certain relationship with VEGF and PCNA (P < 0.05). Conclusion: The increase of the positive rates of MMP-2, PCNA and VEGF indicates that the tumor possesses higher possibility for developing metastasis, proliferation and vascular formation. The interventional treatment with Adp53 or Lipiodol+Ad-p53 can inhibit the growth, metastasis and vascular formation of VX2 liver tumor in experimental rabbits.

    Full Text Available Ectopic adrenocorticotropic hormone (ACTH syndrome is an uncommon disorder and comprises about 15% of all patients with Cushing's syndrome (CS. Duodenal carcinoids are rare, indolent tumors usually associated with a benign progression. We hereby report a rare case of CS resulting from ectopic ACTH secretion from a duodenal neuroendocrine tumor (NET presenting with liver metastasis. A 37-year-old female presented with abdominal discomfort and dyspepsia of 1-month duration. Ultrasound abdomen suggested a well-defined hypoechoic lesion in the left lobe of the liver, suggestive of neoplasia. On clinical examination, she had Cushingoid features and persistent hypokalemia. Midnight ACTH and cortisol levels were grossly elevated at 1027 pg/ml (n < 46 pg/ml and 87.56 μg/dl (n < 7.5 μg/ml, respectively. Both overnight and high-dose dexamethasone suppression test confirmed nonsuppressed cortisol levels - 86.04 and 84.42 μg/dl (n < 1.8 μg/ml, respectively. Magnetic resonance imaging brain showed a structurally normal pituitary gland. Computed tomography scan of the abdomen revealed hepatic lesion with bilateral adrenal enlargement. A diagnosis of ectopic ACTH-dependent CS was made. Intraoperatively, a duodenal lesion of 0.5 cm × 0.5 cm was identified alongside an 8 cm × 6 cm exophytic lesion in segment IV of the liver. Frozen section of the duodenal lesion was positive for NET. She underwent a Whipple's surgery, cholecystectomy, and left hepatic lobectomy. Postoperatively, she showed clinical and biochemical remission. Herewith, we report the third case of duodenal carcinoid tumor presenting as ectopic ACTH syndrome and the first with liver metastasis.

    Full Text Available We report a rare presentation of an initially misdiagnosed case of a pseudotumor, which on histopathology was diagnosed as bilateral breast metastases of lobular carcinoma involving multiple extraocular muscles. A 61-year-old lady presented with external ophthalmoplegia and diplopia. Incisional biopsy was performed using a lid crease approach and the patient received radiotherapy and hormonal therapy. Following prolonged hormonal therapy, complete remission was achieved, with improvement in ocular motility and resolution of diplopia, about 18 months after the initial presentation. Multiple extraocular muscle involvement by breast carcinoma metastasis is very rare and should be considered in the differential diagnosis, especially in patients with a prior history of breast carcinoma.

    At time of presentation, fewer than 10% of patients have metastatic breast cancer. The most common sites of metastasis in order of frequency are bone, lung, pleura, soft tissue, and liver. Breast cancer metastasis to the uterus or gallbladder is rare and has infrequently been reported in the English literature. A 47 year old female with a recent history of thrombocytopenia presented with abnormal vaginal bleeding. Pelvic ultrasound revealed multiple uterine fibroids and endometrial curettings revealed cells consistent with lobular carcinoma of the breast. Breast examination revealed edema and induration of the lower half of the right breast. Biopsy of the right breast revealed invasive lobular carcinoma. Bone marrow aspiration obtained at a previous outpatient visit revealed extensive involvement by metastatic breast carcinoma. Shortly after discharge, the patient presented with acute cholecystitis and underwent cholecystectomy. Microscopic examination of the gallbladder revealed metastatic infiltrating lobular carcinoma. The final diagnosis was invasive lobular carcinoma of the right breast with metastasis to the bone marrow, endometrium, gallbladder, regional lymph nodes, and peritoneum. The growth pattern of invasive lobular carcinoma of the breast is unique and poses a challenge in diagnosing the cancer at an early stage. Unlike other types of breast cancer, it tends to metastasize more to the peritoneum, ovary, and gastrointestinal tract. Metastasis to the endometrium or gallbladder is rare. Metastatic spread should be considered in the differential diagnosis of patients with invasive lobular breast carcinoma presenting with abnormal vaginal bleeding or acute cholecystitis.

    Transitional cell carcinoma (TCC) of the female urethra is a rare urological malignancy, and intracranial metastasis of this cancer has not yet been reported in the literature. This review is intended to present a case of multiple intracranial metastasis in a female patient with a remote history of primary urethral TCC. A 49-year-old woman, presented with a prolapsed mass in urethral orifice that was diagnosed as primary urethral TCC with distant lung and multiple bone metastases. The patient subsequently underwent chemotherapy under various regimens. A year later, the patient developed headache and vomiting which as was found to be due to multiple intracranial metastasis. The patient underwent surgical resection of the largest lesion located on the cerebellum, and consecutively gamma knife radiosurgery was performed for other small-sized lesions. Pathological examination of the resected mass revealed a metastatic carcinoma from a known urethral TCC. Serial work-up of systemic metastasis revealed concomitant aggravation of lung, spleen, and liver metastasis. The patient died of lung complication 2 months after the diagnosis of brain metastasis. To the best of our knowledge, this is the first reported case of cerebral metastasis from primary urethral TCC, with pathological confirmation. As shown in intracranial metastasis of other urinary tract carcinoma, this case occurred in the setting of uncontrolled systemic disease and led to dismal prognosis in spite of aggressive interventional modalities

    Twenty-one nodules of hepatocellular carcinoma (HCC) and eighteen nodules of liver metastasis, which were confirmed pathologically, were investigated by MRI before operation and MRI of resected liver specimen. Pre-operative MRI pointed out all HCCs and seventeen metastases. STIR method was most useful for detection of HCCs. T2WI and STIR method were most useful for detection of liver metastases. Pre-operative MRI also revealed 93% of capsule formation, 29% of septal formation, 75% of fatty metamorphosis of HCC and 75% of necrosis of liver metastasis, and post-operative MRI of resected specimens revealed 100% of capsule formation, 71% of septal formation, 75% of fatty metamorphosis of HCC and 88% of necrosis of liver metastasis. T1WI showed a high intensity halo surrounding metastasis. This characteristic peripheral halo was seen in 22% of metastases. These findings corresponded to pathological feature of liver cancer. MRI was thought to be useful diagnostic modality of liver cancer. (author)

    The combined use of anti-angiogenic therapy (AT) and radioimmunotherapy (RIT) may improve the therapeutic outcome in patients with cancer lesions. This hypothesis is based on the ability of AT to suppress tumour endothelial compartments and the direct action of RIT against tumour cells. We previously confirmed this hypothesis in an established subcutaneous xenograft model of colon cancer. The purpose of the current investigation was to determine the benefit of this combination within a liver metastasis model, which mimics treatment of minimal disease in an adjuvant setting. Liver metastases were established in nude mice by intrasplenic inoculation of LS180 colon cancer cells; following such inoculation, metastases of 131 I-A7, an IgG1 anti-colorectal monoclonal antibody, was conducted at 2 weeks. RIT employing an irrelevant IgG1, 131 I-HPMS-1, was implemented for comparison. The weight of liver metastases was measured 4 weeks after cell inoculation. The effect of AT on 131 I-A7 accumulation in metastases was also observed. Toxicity of treatment was monitored by blood cell counts. Monotherapy with 2-ME AT or 131 I-A7 RIT significantly suppressed metastasis growth (P 131 I-A7 RIT. Combination of AT and 131 I-A7 RIT more effectively suppressed the growth to 0.28±0.32 g (P 131 I-HPMS-1 RIT, which suppressed metastasis growth to 2.25±0.88 g, was significant in comparison with the control (P 131 I-HPMS-1 RIT (which suppressed growth to 1.41±0.68 g) was far less effective than the combination of AT and 131 I-A7 RIT. AT did not decrease 131 I-A7 accumulation in metastases. AT did not affect RIT myelotoxicity. The results of this study demonstrating the combined effects of AT and 131 I-A7 RIT in a small metastasis model indicate that such combination therapy may be suitable for the treatment of minimal disease.

    Full Text Available The purpose of this study was to determine whether systemic administration of interferon-alpha (IFN-α can inhibit liver metastasis produced in nude mice by human colon cancer cells. KM12L4 (IFN-α-sensitive or KM12L4 IFNR (IFN-α-resistant cells were injected into the spleen of nude mice. Seven days later, the mice were treated with subcutaneous (s.c. injections of IFN-α (70,000 units/week at different dosing schedules (1, 2, or 7 times/week. Significant inhibition of tumor growth, vascularization and expression of basic fibroblast growth factor (bFGF or matrix metal loproteinase9 (MMP-9 mRNA and protein occurred in mice given daily injections of IFN-α. Kinetic analysis of therapy showed that daily s.c. administrations of 10,000 units of IFN-α induced apoptosis in liver metastasis-associated endothelial cells, followed by inhibition of tumor cell division and apoptosis of tumor cells. These data suggest that the antiangiogenic activity of IFN-α-2a depends on frequent administration of the optimal biologic dose.

    The goal of this study was to investigate the surgical management and outcomes of patients with primary colorectal cancer (CRC) and synchronous liver metastasis (sCRLM). Using a multi-institutional database, we identified 1,004 patients treated for sCRLM between 1982 and 2011. Clinicopathologic and outcomes data were evaluated with uni- and multivariable analyses. A simultaneous CRC and liver operation was performed in 329 (33%) patients; 675 (67%) underwent a staged approach ("classic" staged approach, n = 647; liver-first strategy, n = 28). Patients managed with the liver-first approach had more hepatic lesions and were more likely to have bilateral disease than those in the other 2 groups (p 3 segments) was more common with a staged approach (39% vs 24%; p 0.05). Ninety-day postoperative mortality was 3.0%, with no difference between simultaneous and staged approaches (p = 0.94). The overall median and 5-year survivals were 50.9 months and 44%, respectively; long-term survival was the same regardless of the operative approach (p > 0.05). Simultaneous and staged resections for sCRLM can be performed with comparable morbidity, mortality, and long-term oncologic outcomes. Copyright © 2013 American College of Surgeons.

    Full Text Available In patients with colorectal cancer (CRC that metastasizes to the liver, there are several key goals for improving outcomes including early detection, effective prognostic indicators of treatment response, and accurate identification of patients at high risk for recurrence. Although new therapeutic regimens developed over the past decade have increased survival, there is substantial room for improvement in selecting targeted treatment regimens for the patients who will derive the most benefit. Recently, there have been exciting developments in identifying high-risk patient cohorts, refinements in the understanding of systemic vs localized drug delivery to metastatic niches, liquid biomarker development, and dramatic advances in tumor immune therapy, all of which promise new and innovative approaches to tackling the problem of detecting and treating the metastatic spread of CRC to the liver. Our multidisciplinary group held a state-of-the-science symposium this past year to review advances in this rapidly evolving field. Herein, we present a discussion around the issues facing treatment of patients with CRC liver metastases, including the relationship of discrete gene signatures with prognosis. We also discuss the latest advances to maximize regional and systemic therapies aimed at decreasing intrahepatic recurrence, review recent insights into the tumor microenvironment, and summarize advances in noninvasive multimodal biomarkers for early detection of primary and recurrent disease. As we continue to advance clinically and technologically in the field of colorectal tumor biology, our goal should be continued refinement of predictive and prognostic studies to decrease recurrence after curative resection and minimize treatment toxicity to patients through a tailored multidisciplinary approach to cancer care.

    Background and purpose: radiosurgery of liver metastases is effective but a technical challenge due to respiration-induced movement. The authors report on the initial experience of the combination of active breathing control (ABC registered ) with stereotactic ultrasound (B-mode acquisition and targeting [BAT registered ]) for frameless radiosurgery. Patient and methods: a patient with a solitary, inoperable liver metastasis from cholangiocellular carcinoma is presented. ABC registered was used for tumor/liver immobilization. Tumor/liver position was controlled and corrected using ultrasound (BAT registered ). The tumor was irradiated with a single dose of 24 Gy. Results: using ABC registered , the motion of the tumor was significantly reduced and the overall positioning error was registered allowed a rapid localization of the lesion during breath hold which could be performed without difficulties for 20 s. Overall treatment time was acceptable (30 min). Conclusion: frameless stereotactic radiotherapy with the combination of ABC registered and BAT registered allows the delivery of high single doses to targets accessible to ultrasound with high precision comparable to a frame-based approach.

    Full Text Available Abstract Background Carcinoid tumors are characteristically low grade malignant neoplasms with neuroendocrine differentiation that arise in various body sites, most commonly the lung and gastrointestinal tract, but less frequently the kidneys, breasts, ovaries, testes, prostate and other locations. We report a case of a carcinoid of renal origin with synchronous single liver metastases on radiological studies. Case presentation A 45 year-old patient who presented with abdominal pain was found on CT scan to have lesions in the right ovary, right kidney, and left hepatic lobe. CA-125, CEA, and CA 19-9 were within normal limits, as were preoperative liver function tests and renal function. Biopsy of the liver mass demonstrated metastatic neuroendocrine tumor. At laparotomy, the patient underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy, radical right nephrectomy with lymphadenectomy, and left hepatectomy. Pathology evaluation reported a right ovarian borderline serous tumor, well-differentiated neuroendocrine carcinoma of the kidney (carcinoid with 2 positive retroperitoneal lymph nodes, and a single liver metastasis. Immunohistochemistry revealed that this lesion was positive for synaptophysin and CD56, but negative for chromogranin as well as CD10, CD7, and CD20, consistent with a well-differentiated neuroendocrine tumor. She is doing well one year after her initial surgery, with no evidence of tumor recurrence. Conclusion Early surgical intervention, together with careful surveillance and follow-up, can achieve successful long-term outcomes in patients with this rare malignancy.

    Although the thyroid gland is one of the most vascular organs of the body, metastatic disease in the thyroid is encountered infrequently. However, at autopsy, the incidence rate of thyroid metastasis ranges from 1.25% to 24%. The primary sites are the kidney, lung, breast, and gastrointestinal tract. We report a rare case of a hepatocellular carcinoma metastatic to the thyroid gland. The patient had multiple palpable masses in the anterior and left lateral neck along the internal jugular chain on physical examination 9 months after the initial diagnosis of liver tumor. These masses were confirmed as metastasis from hepatocellular carcinoma by ultrasonography-guided 16-G core needle biopsy. We discuss the sonographic findings of thyroid metastasis and their use as an additional aid for differentiating between unknown primary tumor and thyroid metastasis.

    The patient was a 70-year-old man. He was diagnosed with advanced transverse colon cancer. A computed tomography (CT)revealed liver metastasis and tumor thrombosis of portal vein. We started combination chemotherapy with capecita- bine/oxaliplatin(CapeOX). Perforation of the tumor was observed 5 days after CapeOX therapy was started. Treatment with abscess drainage and ileostmy, infection was controlled and general condition was improved. After 9 courses of CapeOX, we changed chemotherapy regimen to irinotecan/tegafur-gimeracil-oteracilpotassium (IRIS)due to strong side effects. In CT and FDG-PET examination after 8 courses of IRIS, the tumor of transverse colon, liver metastasis, and the tumor thrombosis of portalvein became unclear. A year and 6 months have passed since chemotherapy was started, recurrence was not observed. For the patients with unresectable colorectal cancer, it is necessary to consider multidisciplinary treatments including chemotherapy while considering the general condition of them.

    Introduction: The use of radioguided occult lesion localization prior to surgical excision is increasing, mainly due to the development of new probes and the use of PET-CT. Case report: A 70-year-old male who presented with a metastatic lesion in his liver from a choroidal melanoma. This was located using PET-CT and subsequently located with a low-energy intraoperative gamma probe during the laparotomy. Conclusion: The present case shows that it is possible to excise a hepatic metastasis utilizing the principles of radioguided surgery, even in centers without access to high energy probes. (author)

    Brain metastasis from esophageal carcinoma has been considered rare and survival following esophageal carcinoma with distant metastasis is poor. The purpose of this report was to clarify cumulative incidence and risk factors for brain metastasis after chemoradiotherapy for esophageal carcinoma, and to consider recommended treatments for brain metastasis from esophageal carcinoma. We reviewed 391 patients treated with chemoradiotherapy. Median age was 65 years. Clinical stages were I, II, III, and IV in 32, 47, 150, and 162 patients, respectively. Brain imaging was performed usually when patients revealed neurological symptoms. The 3-year cumulative incidence of brain metastasis after chemoradiotherapy was 6.6%. There were 4 patients with single metastasis and 8 with multiple metastases. Initial clinical stages were II, III, and IV in 1, 2, and 9 patients, respectively. Histology included squamous cell carcinoma in 10 patients and others in 2 patients. Univariate analysis demonstrated M factor, distant lymph node relapse, and recurrent lung and liver metastasis as significant risk factors of brain metastasis (P<0.05). Median survival time after diagnosis of brain metastasis was 2.1 months. Brain metastasis was not directly related to cause of mortality. The causes were extracranial tumor deterioration in 8 patients and infection in 4 patients. Brain metastasis may increase in the future with improving survival from esophageal carcinoma. However, considering the poor survival after diagnosis of brain metastasis, short-term palliative therapy for brain metastasis appears preferable to vigorous long-term therapy. (author)

    Objective: To investigate the clinical metastasis features and the possibility of 3 dimensional radiotherapy of stage IV non-small cell lung cancer (NSCLC). Methods: The clinical materials of 546 patients with stage IV NSCLC and the relationship b T and N stage and metastasis were retrospectively analyzed. Results In 546 patients with stage IV NSCLC, the number with bone metastasis was 294, the number with brain metastasis was 167, the number with lung metastasis was 137, the number with liver metastasis was 79, the number with adrenal gland metastasis was 66, 37 with lymph node metastasis, 35 with subcutaneous metastasis and 10 with other organ metastasis. The number with single organ metastasis was 379 (69.4%) ,in which 37.7% with bone metastasis, 19.8% with brain metastasis, 16.9% with lung metastasis, 7.4% with liver metastasis, 7.4% with adrenal gland metastasis, 4.5% with lymph node metastasis, 5.5% with subcutaneous metastasis and 0.8% with other organ metastasis. The bone metastasis probability of T 3+4 patient was similar with T 1+2 (69.4%, 30.6%, χ 2 = 7.65, P = 0.067), but N 2+3 patient was more than N 0+1 (69.7%, 30.3%, χ 2 = 7.89, P = 0.044). The brain metastasis probability of T 3+4 patient was more than T 1+2 (70.7%, 29.3%, χ 2 = 10.64, P = 0.018), but N 2+3 patient was similar with N 0+1 (54.5%, 45.5%, χ 2 = 7.14, P = 0.079), and N 1+3+3 patient was more than N 0 (86.8%, 13.2%, χ 2 = 10.26, P = 0.024). Conclusions: In 546 patients with stage IV NSCLC, the most common metastatic organ is bone, the second is brain, the third is lung, the forth is liver, followed by adrenal gland; single organ metastasis is more common than multiple organ metastasis. The later the T stage is, the more severe is the metastasis. Through 3 dimensional radiotherapy, not only the quality of life of some stage IV patients is improved, but also the survival time was prolonged observably. (authors)

  8. Expression of E-selectin ligand-1 (CFR/ESL-1) on hepatic stellate cells: implications for leukocyte extravasation and liver metastasis.

    Leukocytes and tumor cells use E-selectin binding ligands to attach to activated endothelial cells expressing E-selectin during inflammation or metastasis. The cysteine-rich fibroblast growth factor receptor (CFR) represents the main E-selectin ligand (ESL-1) on granulocytes and its expression is exclusively modified by alpha(1,3)-fucosyltransferases IV or VII (FucT4 and FucT7). Hepatic stellate cells (HSC) are pericytes of liver sinusoidal endothelial cells. The activation of HSC and transdifferentiation into a myofibroblastic phenotype is involved in the repair of liver tissue injury, liver regeneration and angiogenesis of liver metastases. In the present study, we demonstrated that HSC expressed CFR together with FucT7 and exhibited a functional E-selectin binding activity on their cell surface. Since HSC appear to be oxygen-sensing cells, the expression of E-selectin binding activity was analyzed in HSC under a hypoxic atmosphere. While the expression of the glycoprotein CFR was unaffected by hypoxia, the cell-associated E-selectin binding activity decreased. However, under the same conditions, mRNA expression of the modifying enzyme FucT7 increased. The loss of E-selectin binding activity, therefore, appears to be neither the result of a reduced expression of the modifying transferase nor the expression of the backbone glycoprotein. After the transient transfection of HSC with CFR cDNA, the E-selectin binding activity (ESL-1) was efficiently released into the supernatant. Therefore, we hypothesize that under hypoxia, ESL-1 is shed from activated HSC. Our findings provide a novel perspective on the function of HSC in liver metastasis and inflammatory liver diseases.

    Brain metastasis from uterine cervical cancer is rare, with an incidence of 0.5%, and usually occurs late in the course of the disease. We report a case of uterine cervical cancer with brain metastasis as the initial site of presentation. A 50-year-old woman with headache, vertigo, amnesia and loss of appetite was admitted for persistent vomiting. Contrast enhanced computed tomography showed a solitary right frontal cerebral lesion with ring enhancement and uterine cervical tumor. She was diagnosed with uterine cervical squamous cell carcinoma with parametrium invasion and no other distant affected organs were detected. The cerebral lesion was surgically removed and pathologically proved to be metastasis of uterine cervical squamous cell carcinoma. The patient underwent concurrent chemoradiotherapy, followed by cerebral radiation therapy, but multiple metastases to the liver and lung developed and the patient died 7 months after diagnosis of brain metastasis. © 2015 The Authors.

    We present the case of a 70-year-old woman, with a history of radiation-treated and surgically- resected cervical cancer, who was admitted to our clinic for intermittent sub occlusive symptoms. CT scan revealed a liver nodule and intestinal obstruction. The patient underwent surgery for excision of suspected liver metastasis and resolution of intestinal obstruction.Intraoperatively an ileal tumour was found to be the cause of the obstruction. Anatomo-pathological findings were consistent with an ileal metastasis from the cervical cancer.The liver nodule was only an area of focal steatosis. Celsius.

    Purpose: To evaluate the diagnostic accuracy of qualitative descriptors alone and in combination for the classification of focal liver lesions (FLLs) suspicious for metastasis in gadolinium-EOB-DTPA-enhanced liver MR imaging. Materials and Methods: Consecutive patients with clinically suspected liver metastases were eligible for this retrospective investigation. 50 patients met the inclusion criteria. All underwent Gd-EOB-DTPA-enhanced liver MRI (T2w, chemical shift T1w, dynamic T1w). Primary liver malignancies or treated lesions were excluded. All investigations were read by two blinded observers (O1, O2). Both independently identified the presence of lesions and evaluated predefined qualitative lesion descriptors (signal intensities, enhancement pattern and morphology). A reference standard was determined under consideration of all clinical and follow-up information. Statistical analysis besides contingency tables (chi square, kappa statistics) included descriptor combinations using classification trees (CHAID methodology) as well as ROC analysis. Results: In 38 patients, 120 FLLs (52 benign, 68 malignant) were present. 115 (48 benign, 67 malignant) were identified by the observers. The enhancement pattern, relative SI upon T2w and late enhanced T1w images contributed significantly to the differentiation of FLLs. The overall classification accuracy was 91.3 % (O1) and 88.7 % (O2), kappa = 0.902. Conclusion: The combination of qualitative lesion descriptors proposed in this work revealed high diagnostic accuracy and interobserver agreement in the differentiation of focal liver lesions suspicious for metastases using Gd-EOB-DTPA-enhanced liver MRI.

    A 19-year-old man suffering from testicular choriocarcinoma presented to the dermatology department with a cutaneous metastasis on his head. This metastasis was the first sign of disease that led to medical consultation. Histopathology revealed cytotrophoblasts and syncytiotrophoblasts, the later expressing human chorionic gonadotropin antigen. Whole body computed tomography showed multiple metastases of the brain, lung, liver, bone, paraaortic lymph nodes and left uvea; the primary was found in the left testicle. Despite neurosurgical intervention and chemotherapy the patient died 9 days after the biopsy of the cutaneous metastasis. Cutaneous metastases of testicular choriocarcinoma are exceptionally rare, with fewer than a dozen cases reported in the English-language literature. The present case highlights that testicular choriocarcinoma metastatic to the skin should be included in the differential of cutaneous scalp tumors. © 2018 John Wiley & Sons A/S.

    Purpose: To determine whether baseline CT texture analysis of hepatic metastasis from colorectal cancer (CRC) is predictive of therapeutic response after cytotoxic chemotherapy. Materials and methods: 235 patients with liver metastasis from CRC who underwent CT and cytotoxic chemotherapy using FOLFOX and FOLFIRI were divided into derivation cohort (n = 145) and validation cohort (n = 90). The CT texture of the hepatic metastasis was quantified using baseline CT. We analyzed the independent predictor for the response from derivation cohort and validated it using validation cohort. We also compared texture features between included four CT scanners. Results: 89 responding and 146 non-responding patients were evaluated. In the derivation cohort, lower skewness (OR, 6.739) in 2D, higher mean attenuation (OR, 2.587), and narrower standard deviation (SD) (OR, 3.163) in 3D were independently associated with response to chemotherapy. However, only lower skewness (P=0.213) on 2D and narrower SD on 3D analysis (P=0.097) did not show a significant difference on either CT scanner. When applied to the validation set, the lower skewness on 2D (AUC = 0.797) and narrower SD on 3D (AUC = 0.785) showed good performance. Conclusion: CT texture analysis is useful for prediction of therapeutic response after cytotoxic chemotherapy in patients with liver metastasis from colorectal cancer.

    Objectives There is controversy about the roles of locoregional therapies in patients with liver metastases from breast cancer (LMBC). The aim of this study was to analyse survival after laparoscopic radiofrequency ablation (RFA) of LMBC and to compare this with survival in patients receiving systemic therapy (ST) alone. Methods During 1996–2011, 24 patients who had failed to respond or had shown an incomplete response to ST underwent laparoscopic RFA for LMBC. Outcomes in these patients were compared with those in 32 patients with LMBC matched by tumour size and number, but treated with ST alone. Clinical parameters and overall survival were compared using t-tests, chi-squared tests and Kaplan–Meier analysis. Results The groups were similar in hormone receptor status and chemotherapy exposure. In the laparoscopic RFA and ST groups, respectively, the mean ± standard deviation size of the dominant liver tumour and the number of tumours per patient were 3.7 ± 0.4 cm and 2.4 ± 0.4 cm, and 2.6 ± 0.4 tumours and 3.3 ± 0.4 tumours, respectively. These differences were not significant. At a median follow-up of 20 months in the laparoscopic RFA group, 42% of patients were found to have developed local liver recurrence, 63% had developed new liver disease and 38% had developed extrahepatic disease. Overall survival after the diagnosis of liver metastasis was 47 months in the laparoscopic RFA group and 9 months in the ST-only group (P = 0.0001). Five-year survival after the diagnosis of liver metastasis was 29% in the RFA group and 0% in the ST-only group. Conclusions This is the first study to compare outcomes in RFA and ST, respectively, in LMBC. The results show that survival after laparoscopic RFA plus ST is better than that after ST alone.

    Full Text Available Nasopharyngeal carcinoma (NPC is prevalent in Taiwan and is characterized by a high frequency of nodal metastasis. The most common organs with distal metastases are the bones, lungs, and liver, with extremely rare cases to the pericardium. Herein, we report a rare case with NPC who presented with dyspnea and orthopnea. Serial studies, including pericardial biopsy, revealed NPC with pericardial metastasis and pericardial effusion. The tumor cells of both the original and metastatic tumors were positive for Epstein–Barr virus by in situ hybridization. This is the first histologically confirmed case of NPC with pericardial metastasis.

    To evaluate the diagnostic accuracy of qualitative descriptors alone and in combination for the classification of focal liver lesions (FLLs) suspicious for metastasis in gadolinium-EOB-DTPA-enhanced liver MR imaging. Consecutive patients with clinically suspected liver metastases were eligible for this retrospective investigation. 50 patients met the inclusion criteria. All underwent Gd-EOB-DTPA-enhanced liver MRI (T2w, chemical shift T1w, dynamic T1w). Primary liver malignancies or treated lesions were excluded. All investigations were read by two blinded observers (O1, O2). Both independently identified the presence of lesions and evaluated predefined qualitative lesion descriptors (signal intensities, enhancement pattern and morphology). A reference standard was determined under consideration of all clinical and follow-up information. Statistical analysis besides contingency tables (chi square, kappa statistics) included descriptor combinations using classification trees (CHAID methodology) as well as ROC analysis. In 38 patients, 120 FLLs (52 benign, 68 malignant) were present. 115 (48 benign, 67 malignant) were identified by the observers. The enhancement pattern, relative SI upon T2w and late enhanced T1w images contributed significantly to the differentiation of FLLs. The overall classification accuracy was 91.3 % (O1) and 88.7 % (O2), kappa = 0.902. The combination of qualitative lesion descriptors proposed in this work revealed high diagnostic accuracy and interobserver agreement in the differentiation of focal liver lesions suspicious for metastases using Gd-EOB-DTPA-enhanced liver MRI. © Georg Thieme Verlag KG Stuttgart · New York.

    The impact of associating liver partition and portal vein occlusion for staged hepatectomy (ALPPS) on tumor growth activity was investigated. A BALB/c mouse model (male, 8-10 weeks old) of liver metastasis labeled by red fluorescent protein was established. Changes in future liver remnant (FLR) volumes, tumor growth activity, and levels of cytokines and growth factors in liver tissues during the treatment period were compared among the models involving ALPPS, portal vein ligation (PVL), or sham operation. The ratio of the FLR volume to body weight at 24 h after the procedure was greater for ALPPS (4.45 ± 0.12 × 10 -2 ) than for PVL (3.79 ± 0.12 × 10 -2 ; P = 0.003) and sham operation (3.18 ± 0.16 × 10 -2 ; P < 0.001). No differences in tumor progression in the FLR were observed at any time point after the procedures. Within the deportalized liver (DL), although tumor progression was observed during a later period after ALPPS (9 days postoperative) and PVL (12 days postoperative), no acceleration of tumor growth after ALPPS was observed in an early period similar to PVL. ALPPS induces a rapid increase in FLR volume and avoids remnant tumor progression during the early postoperative period.

    We report a case of rhabdomyolysis related to S-1 plus oxaliplatin(SOX)therapy for liver metastasis of gastric cancer. A 76- year-old man who had received SOX therapy for metastatic gastric cancer was admitted to our hospital for a chief complaint of fatigue and weakness. He diagnosed with rhabdomyolysis related to SOX therapy because of his symptoms and because his laboratory studies showed significant elevation of his serum creatine kinase(CK)level. The symptoms disappeared and the CK level normalized following large-volume transfusions. Rhabdomyolysis following SOX therapy is a very rare, but severe adverse event. This is the first detailed case report of rhabdomyolysis related to SOX therapy.

  19. M402, a novel heparan sulfate mimetic, targets multiple pathways implicated in tumor progression and metastasis.

    He Zhou

    Full Text Available Heparan sulfate proteoglycans (HSPGs play a key role in shaping the tumor microenvironment by presenting growth factors, cytokines, and other soluble factors that are critical for host cell recruitment and activation, as well as promoting tumor progression, metastasis, and survival. M402 is a rationally engineered, non-cytotoxic heparan sulfate (HS mimetic, designed to inhibit multiple factors implicated in tumor-host cell interactions, including VEGF, FGF2, SDF-1α, P-selectin, and heparanase. A single s.c. dose of M402 effectively inhibited seeding of B16F10 murine melanoma cells to the lung in an experimental metastasis model. Fluorescent-labeled M402 demonstrated selective accumulation in the primary tumor. Immunohistological analyses of the primary tumor revealed a decrease in microvessel density in M402 treated animals, suggesting anti-angiogenesis to be one of the mechanisms involved in-vivo. M402 treatment also normalized circulating levels of myeloid derived suppressor cells in tumor bearing mice. Chronic administration of M402, alone or in combination with cisplatin or docetaxel, inhibited spontaneous metastasis and prolonged survival in an orthotopic 4T1 murine mammary carcinoma model. These data demonstrate that modulating HSPG biology represents a novel approach to target multiple factors involved in tumor progression and metastasis.

    Full Text Available Liver metastasis is a major cause of mortality from colorectal cancer (CRC. However, mechanisms underlying this process are largely unknown. Osteopontin (OPN is a secreted phosphorylated glycoprotein that is involved in tumor migration and metastasis. The role of OPN in cancer is currently unclear. In this study, OPN mRNA was examined in tissues from CRC, adjacent normal mucosa, and liver metastatic lesions using quantitative real-time PCR analysis. The protein expression of OPN and its receptors (integrin αv and CD44 v6 was detected by using an immunohistochemical (IHC method. The role of OPN in liver metastasis was studied in established colon cancer Colo-205 and SW-480 cell lines transfected with sense- or antisense-OPN eukaryotic expression plasmids by flow cytometry and cell adhesion assay. Fluorescence redistribution after photobleaching (FRAP was used to study gap functional intercellular communication (GJIC among OPN-transfected cells. It was found that OPN was highly expressed in metastatic hepatic lesions from CRC compared to primary CRC tissue and adjacent normal mucosa. The expression of OPN mRNA in tumor tissues was significantly related with the CRC stages. OPN expression was also detected in normal hepatocytes surrounding CRC metastatic lesions. Two known receptors of OPN, integrin αv and CD44v6 proteins, were strongly expressed in hepatocytes from normal liver. CRC cells with forced OPN expression exhibited increased heterotypic adhesion with endothelial cells and weakened intercellular communication. OPN plays a significant role in CRC metastasis to liver through interaction with its receptors in hepatocytes, decreased homotypic adhesion, and enhanced heterotypic adhesion.

    Global changes in gene expression occur during tumor progression, as indicated by expression profiling of metastatic tumors. How this occurs is poorly understood. SATB1 functions as a genome organizer by folding chromatin via tethering multiple genomic loci and recruiting chromatin remodeling enzymes to regulate chromatin structure and expression of a large number of genes. Here we show that SATB1 is expressed at high levels in aggressive breast cancer cells, and is undetectable in non-malignant breast epithelial cells. Importantly, RNAi-mediated removal of SATB1 from highly-aggressive MDA-MB-231 cells altered the expression levels of over 1200 genes, restored breast-like acinar polarity in three-dimensional cultures, and prevented the metastastic phenotype in vivo. Conversely, overexpression of SATB1 in the less-aggressive breast cancer cell line Hs578T altered the gene expression profile and increased metastasis dramatically in vivo. Thus, SATB1 is a global regulator of gene expression in breast cancer cells, directly regulating crucial metastasis-associated genes, including ERRB2 (HER2/NEU), TGF-{beta}1, matrix metalloproteinase 3, and metastasin. The identification of SATB1 as a protein that re-programs chromatin organization and transcription profiles to promote breast cancer metastasis suggests a new model for metastasis and may provide means of therapeutic intervention.

    The inositol pyrophosphates, molecular messengers containing an energetic pyrophosphate bond, impact a wide range of biologic processes. They are generated primarily by a family of three inositol hexakisphosphate kinases (IP6Ks), the principal product of which is diphosphoinositol pentakisphosphate (IP7). We report that IP6K2, via IP7 synthesis, is a major mediator of cancer cell migration and tumor metastasis in cell culture and in intact mice. IP6K2 acts by enhancing cell-matrix adhesion and decreasing cell–cell adhesion. This action is mediated by IP7-elicited nuclear sequestration and inactivation of the tumor suppressor liver kinase B1 (LKB1). Accordingly, inhibitors of IP6K2 offer promise in cancer therapy.

    AIM: To evaluate the prevalence of John Cunningham virus (JC virus) in a small cohort of patients with colon cancer and to assess its presence in hepatic metastasis. METHODS: Nineteen consecutive patients with histologically diagnosed colon cancer were included in our study, together with ten subjects affected by histologically and serologically diagnosed hepatitis C virus infection. In the patients included in the colon cancer group, JC virus was searched for in the surgical specimen; in the control group, JC virus was searched for in the hepatic biopsy. The difference in the prevalence of JC virus in the hepatic biopsy between the two groups was assessed through the χ2 test. RESULTS: Four out of 19 patients with colon cancer had a positive polymerase chain reaction (PCR) test for JC virus, and four had liver metastasis. Among the patients with liver metastasis, three out of four had a positive PCR test for JC virus in the surgical specimen and in the liver biopsy; the only patient with liver metastasis with a negative test for JC virus also presented a negative test for JC virus in the surgical specimen. In the control group of patients with hepatitis C infection, none of the ten patients presented JC virus infection in the hepatic biopsy. The difference between the two groups regarding JC virus infection was statistically significant (χ2 = 9.55, P = 0.002). CONCLUSION: JC virus may play a broader role than previously thought, and may be mechanistically involved in the late stages of these tumors. PMID:25400458

    Clear-cell sarcomas (CCSs) in the gastrointestinal tract are extremely rare and aggressive tumors. We present the first case of a CCS arising in the ileum and metastasizing to the liver; our patient was a 60-year-old man. After the resection of the CCS and the liver metastases, a new liver metastasis developed, which was treated via percutaneous radiofrequency ablation only. At the 5-year follow-up, the ablated region was stable without local tumor progression. Percutaneous radiofrequency ablation is a viable local treatment option for recurrent metastases from an ileal CCS if they are detected when small and at an early stage in follow-up studies.

    To determine the clinical relevance of incidentally-found hypervascular micronodules (IHM) on cone-beam computed tomography angiography (CBCTA) in patients with liver metastasis undergoing transarterial (chemo)embolization (TACE/TAE). This was a HIPAA-compliant institutional review board-approved single-institution retrospective review of 95 non-cirrhotic patients (52 men; mean age, 60 years) who underwent CBCTA prior to (chemo)embolic delivery. IHM were defined by the presence of innumerable subcentimetre hepatic parenchymal hypevascular foci not detected on pre-TACE/TAE contrast-enhanced cross-sectional imaging. Multivariate analysis was performed to compare time to tumour progression (TTP) between patients with and without IHM. IHM were present in 21 (22%) patients. Patients with IHM had a significantly shorter intrahepatic TTP determined by a higher frequency of developing new liver metastasis (hazard ratio [HR]: 1.99; 95% confidence interval [CI] 1.08-3.67, P= 0.02). Patients with IHM trended towards a shorter TTP of the tumour(s) treated with TACE/TAE (HR: 1.72; 95% CI: 0.98-3.01, P= 0.056). Extrahepatic TTP was not significantly different between the two cohorts (P= 0.27). Patients with IHM on CBCTA have worse prognosis due to a significantly higher risk of developing new hepatic tumours. Further work is needed to elucidate its underlying mechanisms of pathogenesis.

    Hamada, Yoshihiro; Nakayama, Yoshifuku

    Invasive ductal carcinoma of the pancreas (IDCP) predominantly causes death through liver metastasis (LM) and peritoneal dissemination with local recurrence. However, whether its venous invasion is from the enlarged carcinoma accompanied by tumor growth, or from a distinct carcinoma group, for which venous invasion is facilitated by proximity to the origin, is unclear. We analyzed the correlation between LM and venous invasion in patients with small IDCP tumors. Of 388 patients who were diagnosed with IDCP, 20 (5.2%) had tumors with diameters IDPC. Patients in whom ≥60% of veins were invaded by IDCP should be prepared for LM. Copyright © 2017 IAP and EPC. Published by Elsevier B.V. All rights reserved.

    We present the case of a 42-year-old man with a painful mass lesion in the right shoulder that was detected by contrast-enhanced computed tomography (CT) and 18 F-fluoro-2-deoxyglucose ( 18 F-FDG) positron emission tomography (PET)/CT. Excisional biopsy revealed infiltration of plasma cells with anaplastic features, consistent with solitary plasmacytoma (PC). Serum analysis showed elevation of serum free lambda light chain levels (27.78 mg/l), with an abnormally high kappa:lambda ratio (2.33) and high total proteins (10.4 g/dl). Serum protein electrophoresis revealed an M spike in the gamma-globulin region (56.1 %=5.8 g/dl). Subsequently, 18 F-FDG PET/CT revealed another hypermetabolic mass in the right lobe of the liver. CT-guided biopsy of the liver lesion revealed plasma cell myeloma, consistent with multiple myeloma. Multiple myeloma presenting as nodular liver masses is very rare in clinical practice. In a retrospective review of more than 2,000 patients, Talamo et al. reported only nine cases where there was nodular involvement of the liver by multiple myeloma. The organ most commonly involved was the liver, followed by pancreas, stomach, peritoneum with malignant ascites, colon, rectum, duodenum and ileum. Therefore, the literature published thus far has been limited to a few reports and case series. Among these reports, some had demonstrated the PET or PET/CT findings of nodular liver involvement of multiple myeloma. About 10 % of the solitary myelomas appeared as extramedullary PC or solitary PC of bone. In spite of the advances in therapy, the treatment of multiple myeloma is still palliative. However, solitary PC could be cured by resection or radiation therapy. Thus, differentiation between PC and multiple myeloma is essential in making a decision for the appropriate therapeutic regimen. 18 F-FDG PET/CT has the unique ability to detect and characterize malignant lesions in one single examination. Schirrmeister et al. reported that 18 F-FDG PET revealed

    Invasive lobular carcinomas are the second most common type (5% to 15%) of invasive breast carcinomas. The most frequent sites of breast cancer metastasis are the local and distant lymph nodes, brain, lung, liver, and bones; metastasis to the gastrointestinal system, especially to the stomach, is rare. When a mass is detected in an unusual place in a patient with invasive lobular carcinoma, it should be kept in mind that such a mass may be either a second primary carcinoma or the metastasis o...

    Saniya Sharma

    2018-01-01

    Full Text Available Primary splenic angiosarcoma is a rare malignant vascular neoplasm of mesenchymal origin. The tumor is highly aggressive and has a high metastatic potential. It is usually diagnosed on histopathological examination of splenectomy specimen. Only few cases of angiosarcoma diagnosed by fine-needle aspiration (FNA cytology alone have been reported in the literature. The cytologic features of angiosarcoma are heterogeneous, however, diagnosis can be suggested by FNA when vasoformative features are present. A 55-year-old female presented with abdominal pain and hepatosplenomegaly. Computed tomography scan revealed a heterogeneous splenic lesion with liver metastases. FNA from the splenic and liver lesions showed moderately pleomorphic tumor cells closely associated with anastomosing vascular channels. Cell block immunocytochemistry (ICC showed tumor cells positive for CD31, CD34, CD68 as well as for CD99. FNA supplemented by cell block ICC can render a definite diagnosis of primary splenic angiosarcoma with liver metastasis.

  11. Treatment strategies for locally advanced rectal cancer with synchronous resectable liver metastasis

    Youn Young Park

    2018-01-01

    Full Text Available Approximately one-third of patients with colorectal cancer are estimated to be diagnosed with synchronous liver metastasis (LM. The only method to get cured is to achieve curative resection for both primary and LM. When it comes to locally advanced rectal cancer with synchronous LM, determination of the treatment strategy for each individual is a quite complex procedure, because it demands sophisticated consideration for both local and systemic control. Timing for the application of systemic chemotherapy (CTx, determination of a chemotherapeutic agent, radiation dose and fractions, and sequencing of preoperative treatment and surgeries are all essential components for establishing optimal treatment strategies for the patients with this disease. In this article, treatment strategies proposed in the literature will be reviewed in the light of oncologic outcomes and treatment toxicity with their possible advantages and disadvantages. Owing to a lack of concrete evidences for the best strategy, this article can guide authors to a better way of determining more tailored treatment for each individual.

    Distant metastasis accounts for the vast majority of deaths in patients with cancer. Breast cancer exhibits a distinct metastatic pattern commonly involving bone, liver, lung, and brain. Breast cancer can be divided into different subtypes based on gene expression profiles, and different breast cancer subtypes show preference to distinct organ sites of metastasis. Luminal breast tumors tend to metastasize to bone while basal-like breast cancer (BLBC) displays a lung tropism of metastasis. However, the mechanisms underlying this organ-specific pattern of metastasis still remain to be elucidated. In this review, we will summarize the recent advances regarding the molecular signaling pathways as well as the therapeutic strategies for treating breast cancer lung metastasis.

    2014-12-01

    Full Text Available Malignant pheochromocytoma (PCC is a rare condition. Although the liver is the second most frequent site of metastasis in malignant PCC, no definite treatments have been established. Herein, we report a case of liver metastasis of PCC that was successfully treated by transcatheter arterial chemoembolization (TACE. A 69-year-old man was admitted to the Department of Gastroenterology for evaluation of an incidental hepatic mass in August 2013. He had undergone right adrenalectomy in May 2005 and PCC had been confirmed on the basis of histopathological findings. Liver biopsy was performed, and metastatic PCC was diagnosed. The lesion appeared inoperable because of invasion of the portal vein and metastases in the lymph nodes along the hepatoduodenal ligament. Thus, TACE was performed instead. After TACE, symptoms including dizziness and cold sweating improved, and the patient's serum catecholamine levels decreased. On the basis of this case, we believe that TACE may be a useful treatment for liver metastasis in malignant PCC.

    Here, we report the case of a 43-year-old man who was diagnosed with sigmoid colon cancer with synchronous multiple liver metastases following resection of a primary lesion. Subsequent mFOLFOX+BV therapy elicited a marked response in the liver metastases, which led to the patient undergoing hepatic (S7) radiofrequency ablation (RFA), hepatic resection (lateral segmentectomy and partial [S5] resection), and cholecystectomy. Six months later, transluminal RFA was repeated because liver (S7) metastasis recurred, and 8 courses of XELOX plus BV therapy were administered. As obstructive jaundice due to recurrence of the liver metastases developed after a 6 months hiatus in chemotherapy, we endoscopically inserted a biliary stent. Despite reducing IRIS plus BV therapy, obstructive jaundice developed again, and 3 intrahepatic biliary stents were inserted with percutaneous transhepatic biliary drainage. To date, the patient has been alive for 4 years since the initial resection of the primary lesion after undergoing consecutive systemic chemotherapy with different regimens. Some studies have shown that in cases of obstructive jaundice caused by advanced gastrointestinal cancer, longer survival could be expected by reducing the severity of jaundice, suggesting that resuming chemotherapy as well as improving the severity of jaundice could contribute to better outcomes. The patient in the present case was successfully treated twice with biliary drainage for occlusive jaundice and chemotherapy, suggesting that a combination of multidisciplinary therapy and adequate local therapy such as biliary drainage could be important for the treatment of metastatic liver cancer.

Serum protein electrophoresis revealed an M spike in the gamma-globulin region (56.1 %=5.8 g/dl). Subsequently, {sup 18}F-FDG PET/CT revealed another hypermetabolic mass in the right lobe of the liver. CT-guided biopsy of the liver lesion revealed plasma cell myeloma, consistent with multiple myeloma. Multiple myeloma presenting as nodular liver masses is very rare in clinical practice. In a retrospective review of more than 2,000 patients, Talamo et al. reported only nine cases where there was nodular involvement of the liver by multiple myeloma. The organ most commonly involved was the liver, followed by pancreas, stomach, peritoneum with malignant ascites, colon, rectum, duodenum and ileum. Therefore, the literature published thus far has been limited to a few reports and case series. Among these reports, some had demonstrated the PET or PET/CT findings of nodular liver involvement of multiple myeloma. About 10 % of the solitary myelomas appeared as extramedullary PC or solitary PC of bone. In spite of the advances in therapy, the treatment of multiple myeloma is still palliative. However, solitary PC could be cured by resection or radiation therapy. Thus, differentiation between PC and multiple myeloma is essential in making a decision for the appropriate therapeutic regimen. {sup 18}F-FDG PET/CT has the unique ability to detect and characterize malignant lesions in one single examination. Schirrmeister et al. reported that

    Usually, left colon cancer metastasis concerns liver, abdominal lymph nodes and lungs. Other localizations are quite rare occurrences. In spite of this, some uncommon metastasis sites are reported in literature, such as: peritoneum, ovaries, uterus, kidney testis, bones, thyroid, oral cavity and central nervous system. We report two cases of unusual localizations of left colon cancer metastasis localization, one into the retroperitoneal space and the other at the left axillary lynphnodes and between liver and pancreas. In the first reported case the diffusion pathway may have been the lymphatic mesocolic vessels, partially left in place from the previous surgery. In the second case the alleged metastatic lane may have been through the periumbilical lymph nodes to the parasternal lymph nodes and then to the internal mammary ones, finally reaching the axillary limph nodes.

    2008-04-01

    Full Text Available Abstract Background Occurrence of tumors at multiple sites is a hallmark of malignant cancers and contributes to the high mortality of cancers. The formation of multi-site cancers (MSCs has conventionally been regarded as a result of hematogenous metastasis. However, some MSCs may appear as unusual in the sense of vascular dissemination pattern and therefore be explained by alternative metastasis models or even by non-metastatic independent formation mechanisms. Results Through literature review and incorporation of recent advance in understanding aging and development, we identified two alternative mechanisms for the independent formation of MSCs: 1 formation of separate tumors from cancer-initiating cells (CICs mutated at an early stage of development and then diverging as to their physical locations upon further development, 2 formation of separate tumors from different CICs that contain mutations in some convergent ways. Either of these processes does not require long-distance migration and/or vascular dissemination of cancer cells from a primary site to a secondary site. Thus, we classify the formation of these MSCs from indigenous CICs (iCICs into a new mechanistic category of tumor formation – multigenesis. Conclusion A multigenesis view on multi-site cancer (MSCs may offer explanations for some "unusual metastasis" and has important implications for designing expanded strategies for the diagnosis and treatment of cancers.

    Exosomes are important contributors to cell−cell communication and their role as diagnostic markers for cancer and the pathogenesis for cancer is under intensive investigation. Here, we focus on their role in metastasis-related processes. We discuss their impact regarding promotion of invasion and migration of tumor cells, conditioning of lymph nodes, generation of premetastatic niches and organotropism of metastasis. Furthermore, we highlight interactions of exosomes with bone marrow and stromal components such as fibroblasts, endothelial cells, myeloid- and other immune-related cells in the context of metastases. For all processes as described above, we outline molecular and cellular components for therapeutic intervention with metastatic processes. PMID:28031234

    Full Text Available Hepatocellular carcinoma rarely metastasizes to the orbit. We report a 45-year-old male, HBV+, HIV+, with a past history of a liver transplant for ELSD (end-stage liver disease with hepatocellular carcinoma and recurrent HCC, who presented with proptosis and diplopia of the left eye. CT scans of the head revealed a large, irregular mass in the left orbit causing superior and lateral destruction of the orbital bone. Biopsy specimens of the orbital tumor showed features of metastatic foci of hepatocellular carcinoma. Only 16 other cases of HCC metastasis to the orbit have been described in literature, and this is the first case in a previously transplanted HIV+, HBV+ patient.

    To determine the helical CT findings which help differentiate between focal eosinophilic necrosis (FEN) of the liver and metastasis in patients with underlying gastric or colorectal cancer. In 21 patients with underlying gastric and colorectal cancer examined during a recent 18-month period, the presence of FEN (n=90) was proven at CT. The diagnosis was verified by biopsy in eight patients and by the transient nature of the findings related to peripheral eosinophilia (>10%) in the remainder. For comparison, 20 consecutive patients with pathologically proven hepatic metastasis from gastric or colorectal cancer (n=158) were selected. Single-phase helical CT images (7-mm collimation, pitch 1:1) were independently analyzed in a random order by two blinded readers. The parameters evaluated included the margin (depicted border, fuzzy), shape (spherical, non-spherical), attenuation (subtle hypoattenuation, hypoattenuation), and the presence or absence of rim enhancement. FEN far more frequently showed a fuzzy margin (81%, 84%), subtle hypoattenuation (89%, 91%), and a non-spherical shape (84% for both readers) than metastasis, for which the respective findings were 6%, 22%; 20%, 39%; and 15%, 23%. Rim enhancement was seldom found in FEN (0%, 2%), but was recognized by both readers in 40% of metastases. For all parameters, the results were statistically significant (p < .01), and showed that both readers correctly differentiated FEN from metastasis in 78% of the patients (32/41). Interobserver agreement was, in addition, excellent ({kappa}= 0.66). When focal hepatic lesions with a fuzzy margin, non-spherical shape and subtle hypoattenuation without rim enhancement are found, the possibility of FEN should be considered even in patients with underlying gastrointestinal malignancy.

    Full Text Available BACKGROUND: Although numerous prognostic factors have been reported for colorectal cancer liver metastasis (CRLM, few studies have reported intraoperative blood loss (IBL effects on clinical outcome after CRLM resection. METHODS: We retrospectively evaluated the clinical and histopathological characteristics of 139 patients who underwent liver resection for CRLM. The IBL cutoff volume was calculated using receiver operating characteristic curves. Overall survival (OS and recurrence free survival (RFS were assessed using the Kaplan-Meier and Cox regression methods. RESULTS: All patients underwent curative resection. The median follow up period was 25.0 months (range, 2.1-88.8. Body mass index (BMI and CRLM number and tumor size were associated with increased IBL. BMI (P=0.01; 95% CI = 1.3-8.5 and IBL (P500mL were 71%, 33%, and 0%, respectively (P<0.01. RFS of patients within three IBL volumes at the end of the first year were 67%, 38%, and 18%, respectively (P<0.01. CONCLUSIONS: IBL during CRLM resection is an independent predictor of long term survival and tumor recurrence, and its prognostic value was confirmed by a dose-response relationship.

  2. Combined Therapy for Distant Metastasis of Sacral Chordoma

    Full Text Available Chordomas are known as rare primary malign tumours that have formed from primitive notochord remains. Sacral chordomas grow slowly but locally and aggressively. Chordomas are locally invasive and have low tendency to metastasis and have a poor prognosis in long-term follow-up. Metastasis may be seen in a rate of 5–40% of the chordomas. Metastasis of chordomas is common in liver, lung, lymph nodes, peritoneum, and brain. The treatment approaches, including surgery, have been discussed in the literature before. Susceptibility to radiotherapy and chemotherapy is controversial in these tumours. The success of surgical treatment affects survival directly. In this report, we will report a sacral chordoma case in which an intraperitoneal distant metastasis occurred and discuss the surgical approach.

    To investigated the influence of hyperthermal perfusion chemotherapy combined with immunologic therapy on the immunologic function and levels of circulating tumor cells of the advanced colorectal cancer patients with liver metastasis. We enrolled 98 advanced colorectal cancer patients with liver metastasis that were admitted to this hospital for treatment and were randomly divided into two groups, the observation group (n = 49) and the control group (n = 49). We administered systemic vein chemotherapy for patients in the control group, and hyperthermal perfusion chemotherapy for the patients in the observation group in order to compare the subgroup levels of T lymphocytes, NK cells and immunoglobulin (IgG, IgA, and IgM) in the immune system of patients in both groups. We also assayed the circulating tumor cells (CTC) in the peripheral blood of patients in both groups using the cell search method, and compared the efficacy using response evaluation criteria in solid tumors and the survival rates of patients in both groups using the Kaplan-Meier method. After two treatment courses, the levels of CD3+, CD4+ and CD4+/CD8+ of the patients in the observation group were significantly higher than those of the control group, but the levels of CD8+ of patients in the observation group was lower than that in the control group (pfunctions of patients for the indirect anti-tumor effect, a significant decrease in CTC of patients, and a higher long-term survival rate have been achieved in the treatment with hyperthermal perfusion chemotherapy combined with immunologic therapy for the advanced colorectal cancer patients with liver metastasis. Thus, it can serve as the preferable drug for the treatment of advanced colorectal cancer with liver metastasis.

    Full Text Available Abstract Background Invasion-related genes over-expressed by tumor cells as well as by reacting host cells represent promising drug targets for anti-cancer therapy. Such candidate genes need to be validated in appropriate animal models. Results This study examined the suitability of a murine model (CT26/Balb/C of colorectal liver metastasis to represent clinical liver metastasis specimens using a global gene expression approach. Cross-species similarity was examined between pure liver, liver invasion, tumor invasion and pure tumor compartments through overlap of up-regulated genes and gene ontology (GO-based biological themes on the level of single GO-terms and of condensed GO-term families. Three out of four GO-term families were conserved in a compartment-specific way between the species: secondary metabolism (liver, invasion (invasion front, and immune response (invasion front and liver. Among the individual GO-terms over-represented in the invasion compartments in both species were "extracellular matrix", "cell motility", "cell adhesion" and "antigen presentation" indicating that typical invasion related processes are operating in both species. This was reflected on the single gene level as well, as cross-species overlap of potential target genes over-expressed in the combined invasion front compartments reached up to 36.5%. Generally, histopathology and gene expression correlated well as the highest single gene overlap was found to be 44% in syn-compartmental comparisons (liver versus liver whereas cross-compartmental overlaps were much lower (e.g. liver versus tumor: 9.7%. However, single gene overlap was surprisingly high in some cross-compartmental comparisons (e.g. human liver invasion compartment and murine tumor invasion compartment: 9.0% despite little histolopathologic similarity indicating that invasion relevant genes are not necessarily confined to histologically defined compartments. Conclusion In summary, cross

    Tumor heterogeneity is a major obstacle for developing effective anticancer treatments. Recent studies have pointed to large stochastic genetic heterogeneity within cancer lesions, where no pattern seems to exist that would enable a more structured targeted therapy approach. Because to date no similar information is available at the protein (phenotype) level, we employed matrix assisted laser desorption ionization (MALDI) image-guided proteomics and explored the heterogeneity of extracellular and membrane subproteome in a unique collection of eight fresh human colorectal carcinoma (CRC) liver metastases. Monitoring the spatial distribution of over 1,000 proteins, we found unexpectedly that all liver metastasis lesions displayed a reproducible, zonally delineated pattern of functional and therapeutic biomarker heterogeneity. The peritumoral region featured elevated lipid metabolism and protein synthesis, the rim of the metastasis displayed increased cellular growth, movement, and drug metabolism, whereas the center of the lesion was characterized by elevated carbohydrate metabolism and DNA-repair activity. From the aspect of therapeutic targeting, zonal expression of known and novel biomarkers was evident, reinforcing the need to select several targets in order to achieve optimal coverage of the lesion. Finally, we highlight two novel antigens, LTBP2 and TGFBI, whose expression is a consistent feature of CRC liver metastasis. We demonstrate their in vivo antibody-based targeting and highlight their potential usefulness for clinical applications. The proteome heterogeneity of human CRC liver metastases has a distinct, organized pattern. This particular hallmark can now be used as part of the strategy for developing rational therapies based on multiple sets of targetable antigens. © 2014 by the American Association for the Study of Liver Diseases.

    2018-04-01

    Full Text Available The radiographic appearance of bone metastases is usually determined by tumor histology and can be osteolytic, osteoblastic, or mixed. We present a patient with coexistent bone metastasis from multiple myeloma and prostate adenocarcinoma who exhibited synchronous bone involvement of both histologies within the same bone lesion, a rare phenomenon that has not been previously reported and led to atypical radiographic findings. The radiograph of a 71-year-old man with thigh swelling and pain demonstrated a lytic femoral lesion. Magnetic resonance imaging (MRI confirmed a destructive process, but showed coexistent metaphyseal sclerosis. Multiple myeloma was suspected by demonstration of monoclonal gammopathy and confirmed by computed tomography (CT-guided biopsy. Incidentally, CT demonstrated areas of sclerosis corresponding to T2 hypointensity on MRI. Further studies revealed osteoblastic spinal metastasis, prostate enhancement on CT and prostate-specific antigen (PSA level of 90 ng/mL, concerning for concomitant prostate neoplasm. After endoprosthetic reconstruction, pathology of the femur identified both plasma cell neoplasm and metastatic prostate adenocarcinoma. An association between prostate cancer and multiple myeloma is hypothesized due to tumor microenvironment similarities and possible common genetic variations, however, coexisting bone metastases have never been reported. This unusual finding explains the discrepant imaging features in our patient and is evidenced that certain clinical situations merit contemplation of atypical presentations of common malignancies even if this leads to additional testing.

    Invasive lobular carcinomas are the second most common type (5% to 15%) of invasive breast carcinomas. The most frequent sites of breast cancer metastasis are the local and distant lymph nodes, brain, lung, liver, and bones; metastasis to the gastrointestinal system, especially to the stomach, is rare. When a mass is detected in an unusual place in a patient with invasive lobular carcinoma, it should be kept in mind that such a mass may be either a second primary carcinoma or the metastasis of an invasive lobular carcinoma. In this report, we present a case of gastric metastasis from triple-negative invasive lobular breast cancer. It is important to make an accurate diagnosis by distinguishing gastric metastasis from breast cancer in order to select the best initial treatment for systemic diseases of breast cancer. Considering our case, healthcare professionals should take into account that cases with invasive lobular breast cancer may experience unusual metastases.

    Purpose: Single-isocenter (SI) volumetric modulated arc therapy has been shown to be an effective and efficient approach to multiple metastasis radiosurgery. However, certain extreme cases raise the question of whether multiple-isocenter (MI) approaches can still generate superior plans. In this study, we ask this question with respect to a clinical case with two very widely separated lesions. Methods: A patient with two widely separated (d = 12cm) tumors was treated with SI-VMAT SRS using 10MV flattening filter free (FFF) beam with high-definition multi-leaf collimator (HD-MLC, 2.5/5mm) in two non-coplanar arcs using concentric rings to enforce steep gradient. Because of lesion positioning with respect to collimator angle selection, lesions were treated by 5mm leaves. We re-planned the case with a congruent arc arrangement but separate isocenter for each lesion. In this manner, lesions were treated by 2.5mm leaves. Conformity index (CI), V50%, and mean brain dose were compared. Results: Neither conformity (CI-SI = 1.12, CI-MI = 1.08) nor V50% (V50%-SI =8.82cc, V50%-MI =8.81cc) were improved by utilizing a separate isocenter for each lesion. Mean brain dose was slightly reduced (dmean-SI = 118.4 cGy, dmean-MI = 88.7 cGy) by using multiple isocenters. Conclusion: For this case with a lesion at the apex of the brain and another distantly located at the base of skull, employing a separate isocenter for each target did not meaningfully improve plan quality. Single-isocenter VMAT has been shown feasible and equivalent to multiple-isocenter VMAT for multiple metastasis cases in general. In this extreme case, single- and multiple- isocenter VMAT were also equivalent. If rotational setup errors are appropriately corrected, the increased delivery efficiency of the single-isocenter approach renders it preferable to the multiple isocenter approach.

    Fluorouracil implants are widely used in peritoneal interstitial chemotherapy. Curative effects have been obtained, but implants have also caused some complications. We performed an analysis of a 66-year-old male patient’s case history, as well as conventional pathological analysis and Raman spectroscopic detection of the diaphragmatic tumor. We also analyzed the underlying causes of this condition to prevent complications and reduce misdiagnoses in future cases. The patient had a history of peritoneal fluorouracil implantation. Pathological analysis of the diaphragmatic mass revealed foreign particles, and Raman detection showed that the mass contained fluorouracil. Fluorouracil implants may persist due to the high concentrations of this drug used in peritoneal chemotherapy. This finding should provide guidance and improve the application of peritoneal implants. In clinical trials, and the diagnosis of liver metastasis should be based on pathological results

    The updated eighth edition of the tumor, node, metastasis (TNM) classification for lung cancer includes revisions to T and M descriptors. In terms of the M descriptor, the classification of intrathoracic metastatic disease as M1a is unchanged from TNM-7. Extrathoracic metastatic disease, which was classified as M1b in TNM-7, is now subdivided into M1b (single metastasis, single organ) and M1c (multiple metastases in one or multiple organs) descriptors. In this article, the rationale for changes in the M descriptors, the utility of preoperative staging with PET/computed tomography, and the treatment options available for patients with oligometastatic disease are discussed.

    Full Text Available Aim: To evaluate the local control of hepatic metastasis with radiofrequency ablation treatment. Materials and Methods: We did a retrospective analysis in 40 patients treated with radiofrequency ablation for hepatic metastasis. The tumors ablated included up to two metastatic liver lesions, with primaries in breast, gastrointestinal tract, cervix, etc. Radiofrequency ablation was performed under general anesthesia in all cases, using ultrasound guidance. Radionics Cool-Tip RF System was used to deliver the treatment. Results: The median age of patients treated was 49 years. There were 13 female and 27 male patients. The median tumor size ablated was 1.5 cm (0.75-4.0 cm. A total of 52 radiofrequency ablation cycles were delivered. Successful ablation was achieved in all patients with hepatic metastasis less than 3 cm in size. Pain was the most common complication seen (75%. One patients developed skin burns. At 2-year follow-up 7.5% of patients had locally recurrent disease. Conclusions: Radiofrequency ablation is a minimally invasive treatment modality. It can be useful in a select group of patients with solitary liver metastasis of less than 3 cm size.

    Choroidal metastasis from colorectal cancer is rare, and there have been no reported cases of such metastasis from early colorectal cancer. We report a case of choroidal metastasis from early rectal cancer. A 61 year-old-man experienced myodesopsia in the left eye 2 years and 6 months after primary rectal surgery for early cancer, and was diagnosed with left choroidal metastasis and multiple lung metastases. Radiotherapy was initiated for the left eye and systemic chemotherapy is initiated for the multiple lung metastases. The patient is living 2 years and 3 months after the diagnosis of choroidal metastasis without signs of recurrence in the left eye, and continues to receive systemic chemotherapy for multiple lung metastases. Current literatures have few recommendations regarding the appropriate treatment of choroidal metastasis from colorectal cancer, but an aggressive multi-disciplinary approach may be effective in local regression. This is the first report of choroidal metastasis from early rectal cancer. We consider it important to enforce systemic chemotherapy in addition to radiotherapy for choroidal metastasis from colorectal cancer. Copyright © 2014 The Authors. Published by Elsevier Ltd..

    The patient, a 65-year-old male with far advanced gastric cancer of H3N4 (Stage 4), was assumed inoperable on admission and chemotherapy using CDDP, MMC and UFT(PMU) was carried out. As a result, the levels of AFP and CEA were reduced notably, and PR effects were recognized in liver and lymphnode metastatic lesion. Thus, 2 months later, reduction surgery was performed, during which primary lesion was resected and a reservoir tube for chemotherapy was placed in the common hepatic artery. Subsequently, the chemotherapy with Etoposide added to PMU(PMUE) was continued by utilization of a reservoir, so that liver metastasis decreased more than 90% from the maximum. However, metastasis lesions of left lobe of the liver had enlarged with reincrease of AFP and CEA since 6 months after the operation. A month later left lobectomy of the liver was performed. Residual metastases of the liver were then enlarged. PMUE with Ca antagonist was used with little effect then. The patient died of liver failure 15 months after initial admission.

We report an atypical presentation of lung LCNEC was diagnosed from a metastatic nodule on the breast. Our patient is a 59-years-old woman that presented in March 2014 nonproductive cough. A CT scan showed multiple brain, lung, adrenal gland and liver secondary lesions; moreover, it revealed a breast right nodule near the chest measuring 1.8 cm. The breast nodule and lung lesions were biopsied and their histology and molecular diagnosis were LCNEC of the lung. To our knowledge, this is the first documented case of breast metastasis from LCNEC of the lung. Furthermore, breast metastasis from extramammary malignancy is uncommon and its diagnosis is difficult but important for proper management and prediction of prognosis. Therefore, a careful clinical history with a thorough clinical examination is needed to make the correct diagnosis. Moreover, metastasis to the breast should be considered in any patient with a known primary malignant tumor history who presents with a breast lump. Anyhow, pathological examination should be performed to differentiate the primary breast cancer from metastatic tumor. Therefore, an accurate diagnosis of breast metastases may not only avoid unnecessary breast resection, more importantly it is crucial to determine an appropriate and systemic treatment. © 2015 John Wiley & Sons Ltd.

    Lung cancer is one of the most commonly diagnosed cancers in both men and women. Although the most frequent sites of distant metastasis of lung cancers are the pleura, liver, adrenal glands, skeletal system and brain, perianal region has been rarely reported as a metastasis site. A male patient was admitted to our emergency room with a long standing perianal abscess. During abscess drainage, a mass was noticed at the base of the abscess pouch, and thus a biopsy was taken. Pathologically, it w...

    Using the technique of Drug Delivery System, we experimentally attempted to examine whether the preventive i.v. administration of BRM entrapped in liposomes is useful or not for the cancer metastasis to the liver. As a BRM, we used Lentinan. The liposome used as a carrier in our study showed high stability both in vivo and in vitro with the mol ratio of phosphatidylcholine: cholesterol of 1. Also, high accumulation to reticuloendothelial system was evidenced. NK cell activity in the spleen and the liver on the day of the administration of AH60C hepatoma cells (2x10 6 cells) was higher by 1.3-2.3 times than those of the other groups. The survival ratio of tumor cells in the liver 8 h of tumor cells administration was significantly lower (P<0.01) than in the other groups. Rats with cancer metastasis to the liver on 30th day after the tumor cells administration were significantly decreased (P<0.01). These results suggested the usefulness of the i.v. administration of Lentinan entrapped in liposomes. (orig.)

    An unusual case of infective endocarditis and concurrent multiple liver abscesses both caused by Streptococcus anginosus in a splenectomised patient is reported. The microorganism is a very rare cause of endocarditis and its presentation with multiple liver abscesses is highly unusual. It was initially misdiagnosed as Streptococcus sanguinis and issues relating to the different clinical presentations of S. anginosus including the rare cases of endocarditis, the role of the patient's splenectomy and problems that may contribute to its potential laboratory misidentifications are discussed. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

    To evaluate the pattern of distant lymph node metastasis in colorectal carcinoma and its correlation with distant organ metastasis. We retrospectively reviewed abdominal CT scans of 46 patients with pathologically proven colorectal carcinoma. The incidence of distant lymphadenopathy in colorectal carcinoma was 30.4%(14/46). The most commonly involved distant lymph node was the left paraortic lymph node below the renal hilum(9/25). The most common type of distant lymphadenopathy was solitary type(7/14) and all of these lymphadenopathies were noted in the left paraortic lymph node below the renal hilum. Six cases of left sided colorectal carcinoma showed left paraortic lymphadenopathy with solitary type. The incidence of distant organ metastasis was 17.4%(8/46) and markedly increased if distant lymphadenopathy was multiple and confluent, or confluent type(5/7). The incidence of distant lymphadenopathy in colorectal carcinoma was not high and the most common lymphadenopathy was the left paraortic lymph node with solitary type below the renal hilum. The possibility of distant organ metastasis was high if distant lymphadenopathy was multiple and confluent, or confluent type

The interactions of the tumor cells with hepatic sinusoidal and extrasinusoidal cells (endothelial, Kupffer, stellate, and inflammatory cells) determine their fate. The sinusoidal cells can have a dual role......The liver is host to many metastatic cancers, particularly colorectal cancer, for which the last 2 decades have seen major advances in diagnosis and treatment. The liver is a vital organ, and the extent of its involvement with metastatic disease is a major determinant of survival. Metastatic cells...... arrested and survived the initial onslaught, tumors can grow within the liver in 3 distinct patterns, reflecting differing host responses, mechanisms of vascularization, and proteolytic activity.

    This investigation was undertaken to evaluate thyroxine-binding globulin (TGB) as a marker of liver tumors, in conjection with the liver scintigram. Of 30 patients with primary hepatocellular carcinoma (PHC), 22 (73.3%) showed significantly higher TBG concentrations. Eight patients (26.7%) showed normal TBG concentrations. In the case of 27 our of 30 patients with definite liver tumors, defects were apparent on the scintigrams. But seven of them had normal TBG concentrations in spite of the defects on the scintigrams. Out of 33 postoperative patients with liver metastasis, 28 (84%) had a raised TBG concentration. Only five (15.2%) had a normal TBG level. In 31 patients (93.9%) out of 33 with liver metastasis, a definite diagnosis was made on the basis of the liver scintigram. In 28 (90.3%) of these 31 people, the TBG concentration was higher than normal. Among 63 patients with liver tumors, both primary and metastatic, the test sensitivity for liver tumors was 92.1% (58/63) based on the accuracy of the liver scintigram. It was 79.4% (50/63) based on the TBG measurement. Why TBG increases to such an extent in spite of the euthyroid state remains unexplained. But it may be concluded that elevated TBG with positive liver scintigram furnishes a sensitive, fairly reliable, nonspecific tumor marker to determine liver tumors, especially in the case of liver metastasis.

    2008-01-01

    Neuroblastoma is the most common extracranial solid tumor of childhood, and its metastasis to distant organs such as bone, bone marrow and liver is well documented. However, pancreatic metastasis of neuroblastoma has not yet been reported in the medical literature. We report here on a 4-year old boy who had a metastatic relapse in his pancreas, combined with pancreatitis, after remission of stage 4 neuroblastoma. In conclusion, we present here a very rare case of neuroblastoma that metastasized to the pancreas in a 4- year-old boy. Pancreatic metastasis should be taken into consideration for those patients who are found to have pancreatic nodules concurrent with neuroblastoma

    Abstract Rationale: Fascioliasis is a rare cause of liver abscesses, and its clinical course consists of hepatic phase and biliary phase. Patient concerns: We describe a 58-year-old female patient who presented with a 2-month history of intermittent fever and abdominal pain. An abdominal computed tomography (CT) revealed confluent low-density lesions in the liver. Complete surgical resection of these abscesses was performed, and postoperative pathological examination and serological tests confirmed a diagnosis of fascioliasis. However, 4 months after the surgery, follow-up CT revealed a lesion in the retroperitoneal area. Meanwhile, ultrasonography-guided percutaneous needle biopsy of the retroperitoneal lesion was performed, and a parasitic infection was suspected. Diagnoses: Retroperitoneal metastasis of hepatic phase fascioliasis. Interventions: The patient received parasitic resistance treatment with triclabendazole at a dose of 10 mg/kg/d for 2 consecutive days. Outcomes: After 2 courses of triclabendazole therapy, the retroperitoneal metastasis regressed to a minor lesion. Lessons: To the best of our knowledge, this is the first case report of retroperitoneal metastasis of fascioliasis, aimed at helping recognize the clinical features and treatment options of this rare disease.

    Hepatocellular carcinoma is the most common primary tumor of the liver. Spreading outside the liver usually takes place in advanced stages of the disease, and bone is the third most common site of metastases. We present a case of hepatocellular carcinoma in which the first clinical manifestation was a single metastasis to the carpal bones. The interest of this case lies in the way this hepatocellular carcinoma manifested as well as in the unusual site of the metastasis. Copyright © 2012 SERAM. Published by Elsevier Espana.

    Full Text Available Squamous cell carcinoma of the anus is a relatively uncommon GI malignancy. When it does occur, it metastasizes in only a small minority of patients. Spread of anal squamous cell carcinoma to the brain is exceedingly rare, and has been previously reported only three times in the medical literature. We report the case of a 67 year old male who was diagnosed on presentation with a poorly differentiated anal squamous cell carcinoma that already had a solitary metastasis to the liver. While the tumors were initially responsive to chemoradiotherapy, the patient’s primary and liver lesions recurred. The patient then underwent synchronous abdominoperineal resection for the primary lesion and a liver lobectomy for the metastasis. Soon thereafter, the patient developed focal neurologic symptoms and was found to have an intracranial lesion that on biopsy demonstrated metastatic squamous cell carcinoma. This case highlights the fact that patients with a previous history of anal squamous cell carcinoma can occasionally develop cerebral metastasis. Furthermore, cerebral metastases from anal squamous cell carcinoma portend a dismal prognosis even in the face of aggressive medical and surgical therapy.

    A 65-year-old Chinese male was referred to our hospital for epidermal growth factor receptor (EGFR)-mutated advanced non-small cell lung cancer (NSCLC). Aggressive combined therapy with surgical resection of the right upper lung lesion and chemotherapy was performed. One month later, continued Icotinib treatment was used as magnetic resonance imaging revealed liver metastasis (LM). Interestingly, complete remission of the patient's LM lesions was achieved in six months. To our knowledge, this is the first report documenting a successful case of an NSCLC patient with LM treated with Icotinib after receiving a radical resection for pulmonary carcinoma. Our experience could provide a treatment strategy for patients with similar disease. © 2016 The Authors. Thoracic Cancer published by China Lung Oncology Group and John Wiley & Sons Australia, Ltd.

  18. C/EBPα Short-Activating RNA Suppresses Metastasis of Hepatocellular Carcinoma through Inhibiting EGFR/β-Catenin Signaling Mediated EMT.

    Directory of Open Access Journals (Sweden)

    Full Text Available Hepatocellular carcinoma is associated with high mortality, and tumor metastasis is an important reason for poor prognosis. However, metastasis has not been effectively prevented in clinical therapy and the mechanisms underlying metastasis have not been fully characterized. CCAAT/enhancer-binding protein-α (C/EBPα is a transcriptional regulator with an essential role in tumor metastasis. We used short-activating RNAs (saRNA to enhance expression of C/EBPα. Intravenous injection of C/EBPα-saRNA in a nude mouse liver orthotopic xenograft tumor model inhibited intrahepatic and distant metastasis. C/EBPα-saRNA-treated mice showed increased serum levels of albumin and decreased alanine aminotransferase (ALT, glutamic-oxalacetic transaminase (AST, indicating a role of C/EBPα in improving liver function. Migration and invasion were inhibited in hepatoma cell lines transfected with C/EBPα-saRNA. We also observed an inhibition of epithelial-mesenchymal transition (EMT and suppression of epidermal growth factor receptor (EGFR, EGFR phosphorylation, and β-catenin in C/EBPa-saRNA-transfected cells. Our results suggested that C/EBPα-saRNA successfully inhibited HCC metastasis by inhibiting EGFR/β-catenin signaling pathway mediated EMT in vitro and in vivo.

    Although recent technical advancements are directed toward developing novel assays and methods for detection of micro and macro metastasis, there are still no reports of reliable, simple to use imaging software that could be used for the detection and quantification of metastasis in tissue sections. We herein report a new semiquantitative method for evaluation of metastasis progression in a well established 4T1 orthotopic mouse model of breast cancer metastasis. The new semiquantitative method presented here was implemented by using the Autodesk AutoCAD 2012 program, a computer-aided design program used primarily for preparing technical drawings in 2 dimensions. By using the Autodesk AutoCAD 2012 software- aided graphical evaluation we managed to detect each metastatic lesion and we precisely calculated the average percentage of lung and liver tissue parenchyma with metastasis in 4T1 tumor-bearing mice. The data were highly specific and relevant to descriptive histological analysis, confirming reliability and accuracy of the AutoCAD 2012 software as new method for quantification of metastatic lesions. The new semiquantitative method using AutoCAD 2012 software provides a novel approach for the estimation of metastatic progression in histological tissue sections.

    Full Text Available Metastatic testicular cancers are rare. Primary tumor sources are prostate, lung, and gastrointestinal tract for metastatic testicular cancers. Metastasis of urothelial carcinoma (UC to the testis is extremely rare. Two-thirds of upper tract urothelial carcinoma (UTUC is of invasive stage at diagnosis and metastatic sites are the pelvic lymph nodes, liver, lung, and bone. We report a rare case of metastatic UTUC to the testis which has not been reported before, except one case in the literature. Testicular metastasis of UC should be considered in patients with hematuria and testicular swelling.

    Background: Gall bladder carcinoma is one of the most common cancers in India. Gall bladder cancer with metastasis to the breast is very rare. Herein we intend to report a case of carcinoma gall bladder with breast metastasis and a short review of the literature. Methods: This report describes an interesting and unusual case of gall bladder carcinoma presenting with breast metastasis. Case report: A 38-year lady presented with complaints of right abdominal pain. Bilateral breast examination showed 2 2 cm palpable lump in the upper outer quadrant of the left breast. Contrast-enhanced CT of the abdomen and pelvis showed circumferential thickening of gall bladder with the loss of fat plane with the adjacent liver parenchyma. Biopsy from the breast lump was reported as metastatic adenocarcinoma compatible with primary in the gall bladder. Whole body PET-CT showed gall bladder mass with abdominal and pelvic nodes with metastasis to liver, left breast, C7 vertebral body and left supra-clavicular node. She was diagnosed to have disseminated carcinoma gall bladder with liver, breast and supraclavicular nodal metastasis. She received palliative chemotherapy with gemcitabine and carboplatin and radiotherapy to C7 vertebra. After receiving 3 cycles of chemotherapy, chemotherapy was changed to the second line with single agent capecitabine. In spite of two lines of chemotherapy, she succumbed to disease progression and expired. Conclusion: There are limited examples of gall bladder adenocarcinoma with simultaneous metastasis to breast in the English literature. Our case showed an unusual dissemination of gall bladder cancer

    We investigated the effect of a bovine milk protein, lactoferrin (LF–B), and a pepsin–generated peptide of LF–B, lactoferricin (Lfcin–B), on inhibition of tumor metastasis produced by highly metastatic murine tumor cells, B16–BL6 melanoma and L5178Y–ML25 lymphoma cells, using experimental and spontaneous metastasis models in syngeneic mice. The subcutaneous (s.c.) administration of bovine apo–lactoferrin (apo–LF–B, 1 mg/mouse) and Lfcin–B (0.5 mg/monse) 1 day after tumor inoculation significantly inhibited liver and lung metastasis of L5178Y–ML25 cells. However, human apo–lactoferrin (apo–LF–H) and bovine holo–lactoferrin (holo–LF–B) at the dose of 1 mg/mouse failed to inhibit tumor metastasis of L5178Y–ML25 cells. Similarly, the s.c. administration of apo–LF–B as well as Lfcin–B, but not apo–LF–H and holo–LF–B, 1 day after tumor inoculation resulted in significant inhibition of lung metastasis of B16–BL6 cells in an experimental metastasis model. Furthermore, in in vivo analysis for tumor–induced angiogenesis, both apo–LF–B and Lfcin–B inhibited the number of tumor–induced blood vessels and suppressed tumor growth on day 8 after tumor inoculation. However, in a long–term analysis of tumor growth for up to 21 days after tumor inoculation, single administration of apo–LF–B significantly suppressed the growth of B16–BL6 cells throughout the examination period, whereas Lfcin–B showed inhibitory activity only during the early period (8 days). In spontaneous metastasis of B16–BL6 melanoma cells, multiple administration of both apo–LF–B and Lfcin–B into tumor–bearing mice significantly inhibited lung metastasis produced by B16–BL6 cells, though only apo–LF–B exhibited an inhibitory effect on tumor growth at the time of primary tumor amputation (on day 21) after tumor inoculation. These results suggest that apo–LF–B and Lfcin–B inhibit tumor metastasis through different

  3. Automatic Multiple-Needle Surgical Planning of Robotic-Assisted Microwave Coagulation in Large Liver Tumor Therapy.

    Directory of Open Access Journals (Sweden)

    Shaoli Liu

    Full Text Available The "robotic-assisted liver tumor coagulation therapy" (RALTCT system is a promising candidate for large liver tumor treatment in terms of accuracy and speed. A prerequisite for effective therapy is accurate surgical planning. However, it is difficult for the surgeon to perform surgical planning manually due to the difficulties associated with robot-assisted large liver tumor therapy. These main difficulties include the following aspects: (1 multiple needles are needed to destroy the entire tumor, (2 the insertion trajectories of the needles should avoid the ribs, blood vessels, and other tissues and organs in the abdominal cavity, (3 the placement of multiple needles should avoid interference with each other, (4 an inserted needle will cause some deformation of liver, which will result in changes in subsequently inserted needles' operating environment, and (5 the multiple needle-insertion trajectories should be consistent with the needle-driven robot's movement characteristics. Thus, an effective multiple-needle surgical planning procedure is needed. To overcome these problems, we present an automatic multiple-needle surgical planning of optimal insertion trajectories to the targets, based on a mathematical description of all relevant structure surfaces. The method determines the analytical expression of boundaries of every needle "collision-free reachable workspace" (CFRW, which are the feasible insertion zones based on several constraints. Then, the optimal needle insertion trajectory within the optimization criteria will be chosen in the needle CFRW automatically. Also, the results can be visualized with our navigation system. In the simulation experiment, three needle-insertion trajectories were obtained successfully. In the in vitro experiment, the robot successfully achieved insertion of multiple needles. The proposed automatic multiple-needle surgical planning can improve the efficiency and safety of robot-assisted large liver tumor

    The aim of this study was to compare the diagnosability between (18)F-fluorodeoxyglucose (FDG) PET/CT and enhanced multi-detector CT (MDCT) for the detection of liver metastasis (LM) according to the size and location in liver and to evaluate standard maximum standardized uptake values (SUVmax) of all liver metastatic lesions. One hundred two consecutive patients with malignancy who underwent both FDG PET/CT and MDCT for LM evaluation were retrospectively reviewed. Among them, 56 patients with LM were enrolled in this study. LM was confirmed by follow-up imaging studies after at least 6 months or by histopathology. FDG PET/CT and MDCT images were visually analyzed using three-point scale by the consensus of two radiologists and two nuclear medicine physicians. The size and location (central vs. sub-capsular) of the all liver lesions were evaluated using MDCT images. Furthermore, SUVmax of all liver lesions on FDG PET/CT images were calculated. A total of 146 liver lesions were detected by FDG PET/CT and MDCT and 142 of the lesions were diagnosed as LM. The detection rates of MDCT and FDG PET/CT for LM by visual analysis were 77 and 78%, respectively. There was no significant difference of detection rate according to the overall location and size of the lesions. However, FDG PET/CT was more sensitive than MDCT for detecting small and sub-capsular LM. The detection rate of FDG PET/CT for LM was 68% by the cutoff SUVmax of 2.7. Although the diagnosabilities of MDCT and FDG PET/CT for detecting LM were comparable, FDG PET/CT is superior to MDCT for detecting small LM located in the sub-capsular portion of liver.

The expression levels of GABA receptor subunit genes in various HCC cell lines and patients‘ tissues were detected by quantitative real-time polymerase chain reaction and Western blot analysis. Transwell cell migration and invasion assays were carried out for functional analysis. The effects of GABA on liver cancer cell cytoskeletal were determined by immunofluorescence staining. And the effects of GABA on HCC metastasis in nude mice were evaluated using an in vivo orthotopic model of liver cancer. The mRNA level of GABA receptor subunits varied between the primary hepatocellular carcinoma tissue and the adjacent non-tumor liver tissue. GABA inhibited human liver cancer cell migration and invasion via the ionotropic GABA A receptor as a result of the induction of liver cancer cell cytoskeletal reorganization. Pretreatment with GABA also significantly reduced intrahepatic liver metastasis and primary tumor formation in vivo. These findings introduce a potential and novel therapeutic approach for the treatment of cancer patients based on the modulation of the GABAergic system

    Breast cancer is one of the most common malignancies in women. Breast cancer frequently metastasizes to the bones, lungs, and liver. However, the recurrence of distant soft-tissue metastasis except to the chest wall is extremely rare. Here, we describe our experience with a patient in whom invasive lobular carcinoma of the breast with metastasis to the abdominal wall presented as subcutaneous nodules without local recurrence.

    Intracranial malignant solitary fibrous tumor (MSFT) is extremely rare. The authors report a case of MSFT of the right occipital lobe with a rapid recurrence and bilateral lung, multiple bone metastasis. The patient was a 25-year-old male presenting with headache, nausea and visual disturbances without obvious cause. Three times right-side occipital craniotomies were performed and two times postoperative conformal radiotherapy were administered within one year. 4 months after the third time of right-side occipital craniotomy, the patient felt right chest pain and neck pain. Positron emission tomography/computed tomography (PET/CT) showed tumor recurrence of the right occipital lobe and bilateral lung metastasis, multiple bone metastasis including: vertebrae, libs, the left iliac wing, sacrum, the right ischium and upper parts of both femurs. Ultrasound guided puncture biopsy of left-side back of the neck and CT guided puncture biopsy of the third lumbar vertebra were performed. General sample showed grayish white or grayish red with irregular shape. Histopathologically, the tumor was composed of areas of alternating hypercellularity and hypocellularity with spindle-shaped cells, which arranged as fascicular, storiform pattern or patternless pattern, with intervening irregular eosinophilic collagen bundles. Some areas showed hemangiopericytoma-like perivascular pattern and perivascular hyalinization. Tumor cells were pleomorphic with mitotic counts of more than 4 per 10 high power fields and showed coagulative necrosis. Immunohistochemically, tumor cells were diffusely positive for vimentin and CD99, focal positive for CD34, bcl-2 and Actin. Ki-67 labelling index was more than 40%. The final pathological diagnosis was MSFT of the right occipital lobe, metastatic MSFT of left-side back of the neck and the third lumbar vertebra. The MSFT of the right occipital lobe with recurrence and bilateral lung, multiple bone metastasis is extremely rare. Although intracranial

    Inflammation is deemed to play critical roles in tumor progression and metastasis, and an increased neutrophil-lymphocyte ratio (NLR) has been reported to correlate with poor survivals in various malignancies. However, association between NLR elevation and survival outcome in patients with colorectal liver metastasis (CRLM) remains controversial. The aim of this study was to investigate the prognostic significance of elevated NLR in CRLM. The meta-analysis was conducted in adherence to the MOOSE guidelines. PubMed, Embase, Cochrane Library, Web of Science and the Chinese SinoMed were systematically searched to identify eligible studies from the initiation of the databases to May, 2016. Overall survival (OS) and recurrence free survival (RFS) were pooled by using hazard ratio (HR) with corresponding 95% confidence interval (CI). Correlation between NLR values and clinicopathological features was synthesized by using odds ratio (OR) with corresponding 95% CI. A total of 1685 patients from 8 studies (9 cohorts) were analyzed, consisting 347 (20.59%) in high pretreatment NLR value group and 1338 (79.41%) in low pretreatment NLR value one. The results demonstrated that elevated pretreatment NLR was significantly related to poor OS (HR 2.17, 95% CI 1.82-2.58) and RFS (HR 1.96, 95% CI 1.64-2.35) in patients with CRLM. The result of this systematic review and meta-analysis indicated that an elevated pretreatment NLR was closely correlated with poor long-term survival (OS and RFS) in CRLM patients. NLR can be routinely monitored and serve as a useful and cost-effective marker with strong prognostic significance in patients with CRLM.

    The EL4 cell line was previously derived from a lymphoma induced in a C57/BL6 mouse by 9,10-dimethyl-1,2-benzanthracene. In a previous study, EL4 lymphoma cells expressing red fluorescent protein (EL4-RFP) were established and injected into the tail vein of C57/BL6 green fluorescent protein (GFP) transgenic mice. Metastasis was observed at multiple sites which were also enriched with host GFP-expressing stromal cells. In the present study, our aim was to establish an orthotopic model of EL4-RFP. In the present study, EL4-RFP lymphoma cells were injected in the spleen of C57/BL6 GFP transgenic mice as an orthotopic model of lymphoma. Resultant primary tumor and metastases were imaged with the Olympus FV1000 scanning laser confocal microscope. EL4-RFP metastasis was observed 21 days later. EL4-RFP tumors in the spleen (primary injection site), liver, supra-mediastinum lymph nodes, abdominal lymph nodes, bone marrow, and lung were visualized by color-coded imaging. EL4-RFP metastases in the liver, lymph nodes, and bone marrow in C57/BL6 GFP mice were rich in GFP stromal cells such as macrophages, fibroblasts, dendritic cells, and normal lymphocytes derived from the host animal. Small tumors were observed in the spleen, which were rich in host stromal cells. In the lung, no mass formation of lymphoma cells occurred, but lymphoma cells circulated in lung peripheral blood vessels. Phagocytosis of EL4-RFP lymphoma cells by macrophages, as well as dendritic cells and fibroblasts, were observed in culture. Color-coded imaging of the lymphoma microenvironment suggests an important role of stromal cells in lymphoma progression and metastasis.

    Colorectal cancer (CRC) is a leading cause of death in the elderly and about 20% of these patients present metastasis at diagnosis, most often in the liver. Other common metastatic sites include: lung, bone and brain. Isolated splenic metastases are rare, and they are usually a sign of widespread disease. The authors report a case of the rare occurrence of synchronous isolated splenic metastasis, diagnosed by computed tomography in the preoperative staging of a patient with CRC.O câncer color...

    Full Text Available The patient was a 68-year-old man who was admitted to our hospital with a liver tumor. Abdominal ultrasonography and computed tomography revealed a liver tumor 30 mm in diameter. On colonoscopy, a pedunculated tumor with a central depression (20 mm in diameter was observed in the ascending colon, and this tumor was considered to be invading deeply into the submucosal layer. Right hemicolectomy with D3 lymphadenectomy and partial hepatectomy were performed simultaneously. On histopathological examination of the resected specimen, the tumor was a well-differentiated tubular adenocarcinoma with 3,000 μm invasion of the submucosal layer. The liver tumor showed histological findings similar to those of the primary colorectal carcinoma. The pathological stage according to the 7th edition of the TNM classification was stage IV (T1N0M1. Nine months after the operation, computed tomography revealed hepatic hilar lymph node metastases and a great deal of ascites. The patient ultimately died 14 months after the operation.

    Liver metastasis is the main cause of death from colorectal cancer. Alcohol consumption impacts liver function and is suggested to be an independent risk factor for liver metastasis of colorectal cancer, but no experimental evidence supporting this hypothesis has been demonstrated to date. In this study, we investigated the effect of alcohol intake on liver metastasis. We examined colon cancer cell spread from the spleen in mice provided with water (control group), alcohol for 4 weeks before tumor injection (prealcohol), alcohol for 3 weeks after tumor injection (postalcohol), or alcohol throughout the 7-week study (alcohol). Alcohol intake significantly increased hepatic metastatic burden in the prealcohol (2.4-fold, P < 0.001), postalcohol (2.0-fold, P < 0.01), and alcohol groups (2.2-fold, P < 0.001). A fluorescence-based metastasis tracking assay also confirmed an alcohol-induced increase in the abundance of tumor cells in the liver (2.5-fold, P < 0.001). Investigation of the host microenvironment revealed an alcohol-induced inflammatory response marked by elevated TNFα, IL1β, IL6, and IFNγ protein levels, as well as increased expression of intercellular molecule-1 (ICAM1) in hepatic tissues after 4 weeks of alcohol consumption. Moreover, the peripheral blood of mice provided with alcohol for 4 weeks exhibited reduced natural killer and CD8(+) T-cell counts. Collectively, our findings suggest that chronic alcohol consumption accelerates liver metastasis of colorectal cancer cells through alterations to the liver microenvironment and inactivation of immune surveillance.

    Our investigations were carried out in 139 patients with various types of malignancy. Included in the investigations were 20 patients with primary liver tumor. The interval between scintigraphic examination and the histological verification ranged from 3 days to 1 year. In 62 of the patients histopathology revealed liver metastases, while 77 patients showed no liver involvement. We arrived at the correct diagnosis 'liver metastasis' in 50 out of 2 patientes. Fifty six out of 77 patients without histopathological evidence of liver metastases revealed negative scintigrams. In 18 of 20(90%) patients with focal liver disease correct diagnosis was established. Considering the fact that liver scintigraphy is a non-invasive procedure, it can be recommended as screening method. In connection with sonography and computer tomography liver scintigraphy can undoubtedly improve the diagnostic accuracy in detecting liver metastases and primary liver tumors. (orig./MG) [de

    Purpose: To analyze the prognostic factors predicting distant metastasis in patients undergoing adjuvant chemoradiation for extrahepatic bile duct (EHBD) cancer. Methods and Materials: Between January 1995 and August 2006, 166 patients with EHBD cancer underwent resection with curative intent, followed by adjuvant chemoradiation. There were 120 males and 46 females, and median age was 61 years (range, 34-86). Postoperative radiotherapy was delivered to tumor bed and regional lymph nodes (median dose, 40 Gy; range, 34-56 Gy). A total of 157 patients also received fluoropyrimidine chemotherapy as a radiosensitizer, and fluoropyrimidine-based maintenance chemotherapy was administered to 127 patients. Median follow-up duration was 29 months. Results: The treatment failed for 97 patients, and the major pattern of failure was distant metastasis (76 patients, 78.4%). The 5-year distant metastasis-free survival rate was 49.4%. The most common site of distant failure was the liver (n = 36). On multivariate analysis, hilar tumor, tumor size {>=}2 cm, involved lymph node, and poorly differentiated tumor were associated with inferior distant metastasis-free survival (p = 0.0348, 0.0754, 0.0009, and 0.0078, respectively), whereas T stage was not (p = 0.8081). When patients were divided into four groups based on these risk factors, the 5-year distant metastasis-free survival rates for patients with 0, 1, 2, and 3 risk factors were 86.4%, 59.9%, 32.5%, and 0%, respectively (p < 0.0001). Conclusion: Despite maintenance chemotherapy, distant metastasis was the major pattern of failure in patients undergoing adjuvant chemoradiation for EHBD cancer after resection with curative intent. Intensified chemotherapy is warranted to improve the treatment outcome, especially in those with multiple risk factors.

  17. Dominant Expression of DCLK1 in Human Pancreatic Cancer Stem Cells Accelerates Tumor Invasion and Metastasis.

    Full Text Available Patients with pancreatic cancer typically develop tumor invasion and metastasis in the early stage. These malignant behaviors might be originated from cancer stem cells (CSCs, but the responsible target is less known about invisible CSCs especially for invasion and metastasis. We previously examined the proteasome activity of CSCs and constructed a real-time visualization system for human pancreatic CSCs. In the present study, we found that CSCs were highly metastatic and dominantly localized at the invading tumor margins in a liver metastasis model. Microarray and siRNA screening assays showed that doublecortin-like kinase 1 (DCLK1 was predominantly expressed with histone modification in pancreatic CSCs with invasive and metastatic potential. Overexpression of DCLK1 led to amoeboid morphology, which promotes the migration of pancreatic cancer cells. Knockdown of DCLK1 profoundly suppressed in vivo liver metastasis of pancreatic CSCs. Clinically, DCLK1 was overexpressed in the metastatic tumors in patients with pancreatic cancer. Our studies revealed that DCLK1 is essential for the invasive and metastatic properties of CSCs and may be a promising epigenetic and therapeutic target in human pancreatic cancer.

    Full Text Available Multiple pyogenic liver abscesses formed after appendectomy andtheir percutaneous treatment with multiple catheters have been rarelydescribed. We report a case of multiple pyogenic liver abscesses in acritically ill patient, formed after appendectomy and treated successfully by antibiotics and drainage with six catheters that were introduced simultaneously under ultrasound control. Even though this was a case of liver abscess secondary to appendicitis, today very rare in Western countries, but still a serious complication in developing countries, it was successfully resolved by percutaneous drainage, along with antibiotic therapy. Conclusion. We emphasize the advantages of percutaneous treatment compared with surgery regarding the avoidance of perioperative complications and the risks of general anesthesia.

    Full Text Available Lung cancer is one of the most commonly diagnosed cancers in both men and women. Although the most frequent sites of distant metastasis of lung cancers are the pleura, liver, adrenal glands, skeletal system and brain, perianal region has been rarely reported as a metastasis site. A male patient was admitted to our emergency room with a long standing perianal abscess. During abscess drainage, a mass was noticed at the base of the abscess pouch, and thus a biopsy was taken. Pathologically, it was reported as a metastasis of squamous cell carcinoma, therefore some radiological  investigations and endoscopic procedures were performed to determine the primary focus of cancer. A pulmonary mass was revealed in PET/CT, and was considered as primary tumor. Both primary and metastatic perianal tumors can be rarely presented as an abscess formation. In this situation, a biopsy should be performed from the lesion to avoid misdiagnosis.

    A 64-year-old man was transferred to our hospital because of indigestion and jaundice. The initial abdominal CT and MRI revealed a 2.0 cm enhancing mass in the proximal common bile duct (CBD) with several enlarged lymph nodes. The mass was presumed to be a cholangiocarcinoma, and a CBD segmental resection and choledochojejunostomy was performed. However, the final diagnosis was that of a mixed endocrine-exocrine carcinoma, a high-grade neuroendocrine neoplasm. Seven months after the operation, a follow-up abdominal CT study revealed multiple small arterial enhancing nodules in both hepatic lobes. A sono-guided liver biopsy confirmed these as metastastic mixed endocrine-exocrine carcinoma. This case is unique in that the imaging study regarding the neuroendocrine neoplasm of biliary duct has not been previously reported.

    Whereas extensive research has explored the effect of environmental factors on the etiology of specific cancers, the influence of exposures such as smoking on risk of site-specific metastasis is unknown. We investigated the association of cigarette smoking with lung metastasis in esophageal cancer. We conducted a case-control study of esophageal cancer patients from two centers, comparing cases with lung metastases to controls without lung metastases. Information was gathered from medical records on smoking history, imaging results, site(s) of metastasis, and other patient and tumor characteristics. We used logistic regression to assess association. We identified 354 esophageal cancer cases; smoking status was known in 289 (82%). Among patients with lung metastases, 73.6% (39 of 53) were ever smokers, versus 47.8% (144 of 301) of patients without lung metastases [P=0.001; summary odds ratio (OR), 2.52; 95% confidence interval (95% CI), 1.17-5.45; stratified by histology]. Smoking was associated with a nonsignificant increased adjusted odds of lung metastasis (OR, 1.89; 95% CI, 0.80-4.46). Upper esophageal subsite (OR, 4.71; 95% CI, 1.20-18.5), but not histology (squamous OR 0.65,95% CI 0.27-1.60), was associated with lung metastasis. Compared with the combined never/unknown smoking status group, smoking was associated with a significantly increased odds of lung metastasis (OR, 2.35; 95% CI, 1.11-4.97). There was no association between liver metastasis and smoking (OR, 0.88; 95% CI, 0.42-1.83). Smoking is associated with increased odds of lung metastasis from esophageal cancer, and this relationship seems to be site specific. Future studies are needed to determine whether smoking affects the tumor cell or the site of metastasis, and whether this changes the survival outcome.

  2. Boswellic acid suppresses growth and metastasis of human pancreatic tumors in an orthotopic nude mouse model through modulation of multiple targets.

    Directory of Open Access Journals (Sweden)

    Byoungduck Park

    Full Text Available Pancreatic cancer (PaCa is one of the most lethal cancers, with an estimated 5-year survival of <5% even when patients are given the best treatment available. In addition, these treatments are often toxic and expensive, thus new agents which are safe, affordable and effective are urgently needed. We describe here the results of our study with acetyl-11-keto-β-boswellic acid (AKBA, an agent obtained from an Ayurvedic medicine, gum resin of Boswellia serrata. Whether AKBA has an activity against human PaCa, was examined in in vitro models and in an orthotopic nude mouse model of PaCa. We found that AKBA inhibited the proliferation of four different PaCa cell lines (AsPC-1, PANC-28, and MIA PaCa-2 with K-Ras and p53 mutations, and BxPC-3 with wild-type K-Ras and p53 mutation. These effects correlated with an inhibition of constitutively active NF-κB and suppression of NF-κB regulating gene expression. AKBA also induced apoptosis, and sensitized the cells to apoptotic effects of gemcitabine. In the orthotopic nude mouse model of PaCa, p.o. administration of AKBA alone (100 mg/kg significantly inhibited the tumor growth; this activity was enhanced by gemcitabine. In addition, AKBA inhibited the metastasis of the PaCa to spleen, liver, and lungs. This correlated with decreases in Ki-67, a biomarker of proliferation, and CD31, a biomarker of microvessel density, in the tumor tissue. AKBA produced significant decreases in the expression of NF-κB regulating genes in the tissues. Immunohistochemical analysis also showed AKBA downregulated the expression of COX-2, MMP-9, CXCR4, and VEGF in the tissues. Overall these results demonstrate that AKBA can suppress the growth and metastasis of human pancreatic tumors in an orthotopic nude mouse model that correlates with modulation of multiple targets.

    Microwave thermosphere ablation is a new treatment modality that creates spherical ablation zones using a single antenna. This study aims to analyze local recurrence associated with this new treatment modality in patients with malignant liver tumors. This is a prospective clinical study of patients who underwent microwave thermosphere ablation of malignant liver tumors between September 2014 and March 2017. Clinical, operative, and oncologic parameters were analyzed using Kaplan-Meier survival and Cox proportional hazards model. One hundred patients underwent 301 ablations. Ablations were performed laparoscopically in 87 and open in 13 patients. Pathology included neuroendocrine liver metastasis (n = 115), colorectal liver metastasis (n = 100), hepatocellular cancer (n = 21), and other tumor types (n = 65). Ninety-day morbidity was 7% with one not procedure-related mortality. Median follow-up was 16 months with 65% of patients completing at least 12 months of follow-up. The rate of local tumor recurrence rate per lesion was 6.6% (20/301). Local tumor, new hepatic, and extrahepatic recurrences were detected in 15%, 40%, and 40% of patients, respectively. Local recurrence rate per pathology was 12% for both colorectal liver metastasis (12/100) and other metastatic tumors (8/65). No local recurrence was observed to date in the neuroendocrine liver metastasis and in the limited number of patients with hepatocellular cancers. Tumor size >3 cm and tumor type were independent predictors of local recurrence. This is the first study to analyze local recurrence after microwave thermosphere ablation of malignant liver tumors. Short-term local tumor control rate compares favorably with that reported for radiofrequency and other microwave technologies in the literature. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Thyroid angiosarcomas are typically infiltrative and large tumors with very similar clinical findings of anaplastic carcinoma of thyroid. Early hematogenous metastasis is very frequent, but regional lymph node metastasis is quite rare. We present a case of angiosarcoma of the thyroid gland in a 68 years old man with regional lymph node metastasis. Total thyroidectomy with right modified radical neck dissection was applied. Four out of 19 lymph nodes dissected were seen to contain metastasis. Metastatic tumor was composed of sarcomatous areas containing large numbers of blood filled clefts. There after the surgery PET-CT was performed and multiple metastatic involvements were reported. Thyroid angiosarcomas are completely different tumors from angiomatoid anaplastic carcinomas. Longer survival with these tumors is only possible with agressive surgery and in case of regional LN metastasis, neck dissection should be done.

    We report a case of small cell esophageal carcinoma (SCEC) with multiple liver metastases treated with some success by chemotherapy with irinotecan (CPT-11) plus cisplatin (CDDP). Radiologic and endoscopic examination of a 75-year-old man with multiple liver tumors disclosed a 4.0-cm type 2 tumor in the middle third of the esophagus. An endoscopically obtained biopsy specimen was diagnosed as undifferentiated small cell carcinoma. Multiple liver metastases were confirmed but lymph node metastases and distant metastases other than those in the liver were not detected. After six courses of chemotherapy with CPT-11 plus CDDP, the primary lesion showed complete response and liver metastases showed partial response. However, because all lesions almost immediately relapsed or progressed, arterial infusion chemotherapy for liver metastases and radiation for the primary lesion were given as second-line treatment. The primary lesion showed complete response with radiation. Arterial infusion chemotherapy prevented the progression of liver metastases once, but the patient died of liver failure at last. No distant lesions including metastatic lymph nodes were confirmed over the course of his illness, and the patient survived for a year after first diagnosis. Although the prognosis of SCEC is quite unfavorable due to highly aggressive behavior, a better prognosis is possible with effective chemotherapy and second-line treatment is important in improving prognosis

    Full Text Available Brain metastasis (BM has been universally recognized as a poor prognostic factor in non-small cell lung cancer (NSCLC. Epidermal growth factor receptor (EGFR tyrosine kinase inhibitors (TKIs have shown efficacy in treating BM with an EGFR mutation. This paper reports a case of BM patient with EGFR-mutated NSCLC. According to the findings, a complete remission (CR of the BM was achieved by icotinib treatment without conducting a radiotherapy, which was followed by a resection of the primary lung cancer lesion and lymph nodes. After one-year follow-up, the disease progressed to liver metastasis and liver lesion biopsy showed a T790M mutation. The patient responded well to the combination treatment of AZD9291 and icotinib after the failure of transcatheter arterial chemoembolization (TACE. This case report suggests that icotinib has a sustainable anticancer response to BM and the combination with icotinib and AZD9291 is effective for liver metastasis with T790M.

    initially. According to CT or MRI, involvement was supratentorial (n=23), infratentorial (n=2) or at both sites (n=10). Twenty-four patients had multiple lesions and 11 had a single lesion. Precontrast CT imaging show the masses were isodense in 23 cases, hyperdense in three, hypodense in two, and calcified in one. In seven of eight patients who underwent MRI, the lesions showed so signal intensity on T1WI and iso or high signal intensity on T2WI. The most common enhancement pattern was homogeneous nodular (n=20). Among breast cancer patients in whom metastis to the brain occurred, those in whom this happened later survived for longer than those in whom it took place initially. In order to delay brain metastasis and prolong survival, screening for the first distant metastasis is therefore important. The metastasis of breast cancer to the brain was mainly multiple. The most frequent location and postcontrast imaging findings were, respectively, the supratentorium and homogeneous nodular enhancement

    The purpose of this study was to evaluate the independent predictive factors for local tumor progression (LTP) of colorectal liver metastasis (CRLM) after radiofrequency ablation (RFA). Patients with CRLM were included in the analysis if nodules were up to five in number, each nodule was ≤ 5 cm, and RFA was performed in our center from January 2006 to December 2015. Univariate and multivariate analyses to identify the predictors of LTP were performed by using a Cox proportional hazard model. Overall, 58 tumors from 38 patients were included in this study. LTP occurred in 14 tumors from 9 patients. The overall 1- and 3-year LTP rates were 23.5% and 29.4%, respectively. Multivariate analysis showed that tumor size > 2 cm and insufficient ablative margin were two independently significant adverse prognostic factors for LTP (p = 0.045 and 0.022, respectively). The 3-year LTP rates for 33 and 25 tumors with and without sufficient ablative margin were 4.5% and 61.2%, respectively. The difference was statistically significant (p < 0.001). The difference in the 3-year LTP rates according to the tumor size was not statistically significant (p = 0.791). Insufficient ablative margin seems to be the most potent predictor of LTP after RFA of CRLM.

    Full Text Available Penile cancer is a common malignancy in developing countries. It commonly metastasizes to the lymph nodes, lung, liver, and bones. Myocardial metastasis is rare. A 40-year-old male patient presented with ulcerative growth over glans penis. Histologic evaluation of the biopsy sample diagnosed the lesion as squamous cell cancer. Assessment of the stage of the disease revealed cardiac metastasis. Patient received six cycles of chemotherapy. He partially responded, but later succumbed to cardiac failure due to pericardial and pleural effusion.

    Full Text Available Beclin 1 participates in development, autophagy, differentiation, anti- apoptosis, neurodegeneration, tumorigenesis and cancer progression. The roles of Beclin 1 in colorectal carcinogenesis and its subsequent progression are still unclear. Here, the mRNA and protein expression of Beclin 1 were determined in colorectal carcinoma and matched mucosa by Reverse transcriptase-polymerase chain reaction and Western blot. Immunohistochemistry and in situ hybridization (ISH were performed on tissue microarryer with colorectal carcinoma, adenoma and mucosa. The expression of Beclin 1 mRNA and protein was found to be higher in colorectal carcinoma than matched mucosa by real-time PCR and Western blot (p < 0.05. According to the ISH data, Beclin 1 expression was lower in colorectal non-neoplastic mucosa (NNM than adenoma and carcinoma (p < 0.05. Immunohistochemically, primary carcinoma showed stronger Beclin 1 expression than NNM and metastatic carcinoma in the liver (p < 0.05. Beclin 1 protein expression was negatively related to liver and distant metastasis (p < 0.05, but not correlated with age, sex, depth of invasion, lymphatic or venous invasion, lymph node metastasis, tumor-node-metastasis (TNM staging, differentiation or serum carcinoembryonic antigen (CEA concentration (p > 0.05. Survival analysis indicated that Beclin 1 expression was not linked to favorable prognosis of the patients with colorectal carcinoma (p > 0.05. Cox’s model indicated that depth of invasion and distant metastasis were independent prognostic factors for colorectal carcinomas (p < 0.05. It was suggested that Beclin 1 expression is closely linked to colorectal carcinogenesis and distant metastasis of colorectal carcinoma.

    the paper presents a rare case of metachronous gastric metastasis of uterine cervix cancer, clinically manifested through severe pyloric stenosis. 49-year-old patient, operated on in January 2009, with uterine cervix cancer (Squamous cell carcinoma T2bN1M0), is hospitalized in August 2011 with pyloric stenosis: epigastric pains, abundant, stasis, late postprandial emesis, significant weight loss, stomach form visible upon abdomen inspection. Endoscopy: antral stenosis with intact gastric mucosa, and CT-scan: circumferential intramural gastric tumor, stomach dilated in the upper part, lack of cleavage between the tumor and the liver bed of the gall bladder. CEA increased to 13,78 (below 5), CA 19-9 slightly increased 29.9 (below 27). The case is considered as a second neoplasia and a D2 subtotal gastrectomy was performed, with 1 positive ganglion out of 27 on block with atypical hepatectomy of segments 4-5 for liver invasion, the final mounting being Y Roux. The histopathological examination shows a gastric metastasis of squamous carcinoma, of uterine cervix origin, the invaded perigastric ganglion having the same aspect of uterine cervix carcinoma. The post-surgery evolution was favorable, under chemo radiotherapy the patient being alive without relapse at 9 months post-surgery. In the literature there are 2 more cases of gastric metastasis of uterine cervix carcinoma, and 4 of uterine carcinoma without topographic indication, but without the histological documentation of the tumor filiation, without data related to resecability or follow-up, the case at hand being, from this perspective, the first documented resectable metachronous gastric metastasis from a cervix uteri carcinoma.

    The ability to perform rapid back-to-back spiral acquisitions is an important recent technical advantage of spiral CT. this allows imaging of the upper abdomen (liver) during peak arterial enhancement (arterial phase) and during peak hepatic parenchymal enhancement (portal venous phase). Breatheld spiral CT has completely replaced dynamic incremental CT for evaluation of the liver. in selected patients with hyper vascular metastasis (hepatoma, neuroendocrine tumors, renal cell carcinoma, etc.) a biphasic examination is performed with one spiral acquisition obtained during the hepatic arterial phase and a second acquisition during the portal venous phase

    Full Text Available Although extrahepatic metastases from hepatocellular carcinoma (HCC are present in only 5–15% of cases, they are certainly factors associated with poor prognosis. The main sites include lung, lymph nodes, bones, and adrenal glands, in descending order. Metastasis in the central nervous system is extremely rare, and the incidences vary from 0.6 to 1.7%. We report a case of a 54-year-old man previously diagnosed with alcohol-induced cirrhosis of the liver and HCC. The patient was admitted presenting progressive left hemiparesis and headache which started 2 days earlier, with no history of cranioencephalic trauma. After admission, cranial computed tomography revealed an intraparenchymal hemorrhage area with surrounding edema in the right frontal lobe. An angioresonance requested showed a large extra-axial mass lesion located in the right frontal region with well-defined contours and predominantly hypointense signal on T2 sequence. At first, the radiological findings suggested meningioma as the first diagnostic hypothesis. However, the patient underwent surgery. The tumor was completely removed, and the morphological and immunohistochemical findings were consistent with metastatic hepatocarcinoma associated with meningioma. In postoperative care, the patient did not recover from the left hemiparesis and manifested Broca’s aphasia. He had a survival time of 24 weeks, presenting acute liver failure as his cause of death. There is a lack of evidence supporting a specific management of patients with brain metastasis from HCC. Furthermore, there are no studies that evaluate different modalities of therapeutics in brain metastasis of HCC due to the rarity of this condition. Therefore, management must be individualized depending on probable prognostic factors in these patients.

    Aberrant activity of tyrosine-phosphorylated proteins is commonly associated with HCC metastasis. Cell signaling events driven by these proteins are implicated in numerous processes that alter cancer cell behavior. Exploring the activities and signaling pathways of these proteins in HCC metastasis may help in identifying new candidate molecules for HCC-targeted therapy. Hep3B (a nonmetastatic HCC cell line) and MHCC97H (a highly metastatic HCC cell line) were used in this study, and the tyrosine-phosphorylated proteins expressed in these cell lines were profiled by a phosphoproteomics technique based on LC-MS/MS. Protein-protein interaction and functional clustering analyses were performed to determine the activities of the identified proteins and the signaling pathways closely related to HCC metastasis. In both cell lines, a total of 247 phosphotyrosine (pTyr) proteins containing 281 pTyr sites were identified without any stimulation. The involvement of almost 30% of these in liver or liver cancer has not been reported previously. Biological process clustering analysis indicated that pTyr proteins involved in cell motility, migration, protein autophosphorylation, cell-cell communication, and antiapoptosis functions were overexpressed during metastasis. Pathway clustering analysis revealed that signaling pathways such as those involved in EGFR signaling, cytokine- and chemokine-mediated signal transduction, and the PI3K and JAK-STAT cascades were significantly activated during HCC metastasis. Moreover, noncanonical regulation of the JNK cascade might also provide new targets for HCC metastasis. After comparing the pTyr proteins that were differentially expressed during HCC cell metastasis, we selected FER, a nonreceptor tyrosine kinase, and validated its role in terms of both expression and function. The data confirmed that FER might play a critical role in the invasion and metastasis of HCC. The identification of pTyr proteins and signaling pathways associated

    Background. Colorectal Cancer (CRC) is the most common form of cancer diagnosed in Australia across both genders. Approximately, 40%-60% of patients with CRC develop metastasis, the liver being the most common site. Almost 70% of CRC mortality can be attributed to the development of liver metastasis. This study examines the pattern and density of lymphatics in colorectal liver metastases (CLM) as predictors of survival following hepatic resection for CLM. Methods. Patient tissue samples were obtained from the Victorian Cancer Biobank. Immunohistochemistry was used to examine the spatial differences in blood and lymphatic vessel densities between different regions within the tumor (CLM) and surrounding host tissue. Lymphatic vessel density (LVD) was assessed as a potential prognostic marker. Results. Patients with low lymphatic vessel density in the tumor centre, tumor periphery, and adjacent normal liver demonstrated a significant disease-free survival advantage compared to patients with high lymphatic vessel density (P = 0.01, P > 0.01, and P = 0.05, resp.). Lymphatic vessel density in the tumor centre and periphery and adjacent normal liver was an accurate predictive marker of disease-free survival (P = 0.05). Conclusion. Lymphatic vessel density in CLM appears to be an accurate predictor of recurrence and disease-free survival.

    Full Text Available Metastasis occurs with 50% of lung carcinomas, most commonly to lymph nodes, adrenal glands, liver, bone, and brain. It is extremely rare for lung cancer to present with symptoms of a gastrointestinal metastasis and even more so pertaining to the colon. To the best of our knowledge, only 12 such cases have been reported in the literature. We describe a case of a 71-year-old female presenting with refractory iron deficiency anemia that was found to have a lesion in the transverse colon. Pathology revealed adenocarcinoma of the lung and a subsequent lung lesion was discovered in a retrograde fashion.

    Stage IV colorectal cancer is usually an incurable disease. However, patients with resectable metastases have 5-year disease-free survival rates of up to 30%. Even with primarily irresectable disease, cure can be achieved in patients who become operable after neoadjuvant treatment. To improve the prognosis of these patients, highly effective neoadjuvant regimens need to be developed. Here, we report the case of a 62-year-old male patient who had been diagnosed with International Union against Cancer (UICC) stage III colon cancer 7 years previously and now presented with a large, irresectable liver metastasis and enlarged perihepatic lymph nodes. After neoadjuvant treatment with cetuximab, bevacizumab and XELOX, the patient showed a complete remission and underwent surgery. Histopathologically, the resected tissue and lymph nodes were free of residual tumor. To our knowledge, this is the first report of a complete pathological response in a patient with irresectable colorectal cancer after intensive chemotherapy/anti-EGFR/ VEGF antibody therapy. This combination regimen may help to improve the survival rates for patients with irresectable disease. Copyright 2008 S. Karger AG, Basel.

    Purpose: Efficient and accurate 3D liver segmentations from contrast-enhanced computed tomography (CT) images play an important role in therapeutic strategies for hepatic diseases. However, inhomogeneous appearances, ambiguous boundaries, and large variance in shape often make it a challenging task. The existence of liver abnormalities poses further difficulty. Despite the significant intensity difference, liver tumors should be segmented as part of the liver. This study aims to address these challenges, especially when the target livers contain subregions with distinct appearances. Methods: The authors propose a novel multiregion-appearance based approach with graph cuts to delineate the liver surface. For livers with multiple subregions, a geodesic distance based appearance selection scheme is introduced to utilize proper appearance constraint for each subregion. A special case of the proposed method, which uses only one appearance constraint to segment the liver, is also presented. The segmentation process is modeled with energy functions incorporating both boundary and region information. Rather than a simple fixed combination, an adaptive balancing weight is introduced and learned from training sets. The proposed method only calls initialization inside the liver surface. No additional constraints from user interaction are utilized. Results: The proposed method was validated on 50 3D CT images from three datasets, i.e., Medical Image Computing and Computer Assisted Intervention (MICCAI) training and testing set, and local dataset. On MICCAI testing set, the proposed method achieved a total score of 83.4 ± 3.1, outperforming nonexpert manual segmentation (average score of 75.0). When applying their method to MICCAI training set and local dataset, it yielded a mean Dice similarity coefficient (DSC) of 97.7% ± 0.5% and 97.5% ± 0.4%, respectively. These results demonstrated the accuracy of the method when applied to different computed tomography (CT) datasets

    An autopsy case of multiple myeloma which accompanied radiation-induced veno-occlusion of the liver is presented. A 62-year-old woman with a chief complaint of low back pain was diagnosed as having multiple myeloma. Approximately one year later, the patient was treated with chemotherapy, consisting of VCR, MCNU, ADR, PSL, and CPA, and X-irradiation of 30 Gy to the bilateral trunk for medically intractable rib pain. The irradiation field included the entire liver. Six months later, she was admitted to the hospital due to abdominal distention and massive amounts of ascites. Various examinations failed to make a qualitative diagnosis. Postmortem examination revealed fibrotic occlusion of the central vein which is typical for veno-occlusion disease of the liver. This finding was restricted to the area that was not shielded, irrespective of anatomical structure, strongly suggesting radiation-induced veno-occlusion of the liver. (N.K.)

    NADPH oxidase 4 (NOX4), with the sole function to produce reactive oxygen species (ROS), can be a molecular target for disrupting cancer metastasis. Several studies have indicated that lycopene exhibited anti-metastatic actions in vitro and in vivo. However, the role of NOX4 in the anti-metastatic action of lycopene remains unknown. Herein, we first confirmed the anti-metastatic effect of lycopene (0.1-5 μM) on human liver adenocarcinoma SK-Hep-1 cells. We showed that lycopene significantly inhibited NOX4 protein expression, with the strongest inhibition of 64.3 ± 10.2% (P lycopene. Lycopene also significantly inhibited NOX4 mRNA expression, NOX activity, and intracellular ROS levels in SK-Hep-1 cells. We then determined the effects of lycopene on transforming growth factor β (TGF-β)-induced metastasis. We found that TGF-β (5 ng/mL) significantly increased migration, invasion, and adhesion activity, the intracellular ROS level, matrix metalloproteinase 9 (MMP-9) and MMP-2 activities, the level of NOX4 protein expression, and NOX activity. All these TGF-β-induced effects were antagonized by the incubation of SK-Hep-1 cells with lycopene (2.5 μM). Using transient transfection of siRNA against NOX4, we found that the downregulation of NOX4 could mimic lycopene by inhibiting cell migration and the activities of MMP-9 and MMP-2 during the incubation with or without TGF-β on SK-Hep-1 cells. The results demonstrate that the downregulation of NOX4 plays a crucial role in the anti-metastatic action of lycopene in SK-Hep-1 cells.

  5. MYC is a metastasis gene for non-small-cell lung cancer.

    Directory of Open Access Journals (Sweden)

    Ulf R Rapp

    Full Text Available BACKGROUND: Metastasis is a process by which cancer cells learn to form satellite tumors in distant organs and represents the principle cause of death of patients with solid tumors. NSCLC is the most lethal human cancer due to its high rate of metastasis. METHODOLOGY/PRINCIPAL FINDINGS: Lack of a suitable animal model has so far hampered analysis of metastatic progression. We have examined c-MYC for its ability to induce metastasis in a C-RAF-driven mouse model for non-small-cell lung cancer. c-MYC alone induced frank tumor growth only after long latency at which time secondary mutations in K-Ras or LKB1 were detected reminiscent of human NSCLC. Combination with C-RAF led to immediate acceleration of tumor growth, conversion to papillary epithelial cells and angiogenic switch induction. Moreover, addition of c-MYC was sufficient to induce macrometastasis in liver and lymph nodes with short latency associated with lineage switch events. Thus we have generated the first conditional model for metastasis of NSCLC and identified a gene, c-MYC that is able to orchestrate all steps of this process. CONCLUSIONS/SIGNIFICANCE: Potential markers for detection of metastasis were identified and validated for diagnosis of human biopsies. These markers may represent targets for future therapeutic intervention as they include genes such as Gata4 that are exclusively expressed during lung development.

    To investigate risk factors associated with right paraesophageal lymph node (RPELN) metastasis in patients with papillary thyroid carcinoma (PTC) and to determine the indications for right lymph node dissection. Clinicopathologic data from 829 patients (104 men and 725 women) with PTC, operated on by the same thyroid surgery team at the First Affiliated Hospital of Harbin Medical University from January 2013 to May 2017, were analyzed. Overall, 309 patients underwent total thyroidectomy with bilateral lymph node dissection, 488 underwent right thyroid lobe and isthmic resection with right central compartment lymph node dissection, and 32 underwent near-total thyroidectomy (ipsilateral thyroid lobectomy with contralateral near-total lobectomy) with bilateral lymph node dissection. The overall rate of central compartment lymph node metastasis was 43.5% (361/829), with right central compartment lymph node and RPELN metastasis rates of 35.5% (294/829) and 19.1% (158/829), respectively. Tumor size, number, invasion, and location, lymph node metastasis, right central compartment lymph node metastasis, and right lateral compartment lymph node metastasis were associated with RPELN in the univariate analysis, whereas age and sex were not. Multivariate analysis identified tumors with a diameter ≥ 1 cm, multiple tumors, tumors located in the right lobe, right central compartment lymph node metastasis, and right lateral compartment lymph node metastasis as independent risk factors for RPELN metastasis. Lymph node dissection, including RPELN dissection, should be performed for patients with PTC with a tumor diameter ≥ 1 cm, multiple tumors, right-lobe tumors, right central compartment lymph node metastasis, or suspected lateral compartment lymph node metastasis.

    The case is a woman in her 50's. A total glandectomy was performed for her breast cancer on August 8, 1998, and subsequently chemotherapy(5'-DFUR, CMF, uracil.tegafur, CEF, and docetaxel)as well as radiation therapy and surgical resection have been performed for local recurrence. With multiple hepatic metastasis recognized in September, 2007, chemotherapy combined with S-1/paclitaxel(PTX)has been performed. In view of the side effects such as reduction in appetite and leukocyte, the dosage has been reduced as of the second course of treatment. With the disappearance of hepatic metastasis on CT, 6 courses of S-1monotherapy have been performed after completing 6 courses of chemotherapy combined with S-1/ PTX. As of March, 2009, the therapeutic effect shows that continuous CR and outpatient follow-up have been performed while maintaining QOL. Since any chemotherapy after thirdline treatment for recurrent breast cancer has not been established yet, chemotherapy combined with S-1/PTX is considered to be one of the regimens and therefore, the second and thirdphase clinical tests ahead are expected to bring better outcomes.

    Focal fatty infiltration of the liver is a well recognized entity generally characterized by a nonspherical, low-density area without significant mass effect. CT usually distinguishes this from focal liver processes such as abscess or metastasis by its sharply marginated, geographic pattern and lack of mass effect on hepatic and portal veins. Recently, the authors formed a CT scan of the liver in one patient in whom fatty infiltration appeared nodular or rounded. The clinical presentation and radiographic and pathologic features form the basis of this report

    There are sporadic reports in the literature in which radiologic liver and lung lesions found incidentally during follow-up metastatic surveillance were shown to be caused by toxocariasis. The objective of the work discussed in this report was to identify common clinical and histopathological features of toxocariasis resembling metastatic nodules in five patients with gastrointestinal cancer. We retrospectively analyzed clinical features of five gastrointestinal cancer patients with liver or lung nodules mimicking metastasis. Serologic tests for parasitic infestations and pathologic examinations were performed. All five patients were males and three patients had gastric cancer and two had colorectal cancer. All the cases of toxocariasis were confirmed serologically. On follow-up imaging, the lesions improved or resolved, suggestive of the phenomenon of visceral larva migrans. In two patients, liver biopsy was performed and showed eosinophilic abscess. Serologic tests and liver or lung biopsy should be performed aggressively to exclude toxocariasis when patients with underlying gastrointestinal cancer present with hepatic or pulmonary nodules associated with eosinophilia, particularly if the patients have a clinical history of raw animal liver ingestion. Curative surgical intervention should not be excluded just because of multiple nodules in the liver or the lungs.

    Full Text Available Testicular metastases from renal cell carcinoma (RCC are extremely rare. To the best of our knowledge, only 33 cases have been described in the literature. Most of the reported cases are of unilateral testicular metastasis from RCC. We report a case of metachronous ipsilateral testicular metastasis from RCC in a 78-year-old man 6 years after nephrectomy. Scrotal ultrasonography showed a 4 × 5 cm mass in the right testis. Right inguinal orchiectomy was performed for diagnosis. Computed tomography revealed liver and lung metastases. First-line therapy with sunitinib was started in November 2016 for metastatic RCC.

  11. Histone Demethylase RBP2 Is Critical for Breast Cancer Progression and Metastasis

    2014-03-01

    Full Text Available Metastasis is a major clinical challenge for cancer treatment. Emerging evidence suggests that aberrant epigenetic modifications contribute significantly to tumor formation and progression. However, the drivers and roles of such epigenetic changes in tumor metastasis are still poorly understood. Using bioinformatic analysis of human breast cancer gene-expression data sets, we identified histone demethylase RBP2 as a putative mediator of metastatic progression. By using both human breast cancer cells and genetically engineered mice, we demonstrated that RBP2 is critical for breast cancer metastasis to the lung in multiple in vivo models. Mechanistically, RBP2 promotes metastasis as a pleiotropic positive regulator of many metastasis genes, including TNC. In addition, RBP2 loss suppresses tumor formation in MMTV-neu transgenic mice. These results suggest that therapeutic targeting of RBP2 is a potential strategy for inhibition of tumor progression and metastasis.

    Docetaxel has been chosen as one of the most popular anticancer drugs in the treatment of breast cancer for more than a decade. There is increasingly awareness for the occurrence of docetaxel and/or docetaxel-drug-induced liver injury (DILI), although the underlying mechanism of occurrence and its risk factors remain unclear. We conducted a retrospective cohort study to identify non-genetic risk factors for docetaxel-DILI among 647 metastasis breast cancer patients treated with docetaxel-containing regimens. Sixty-seven (10.36%) patients were diagnosed as docetaxel-DILI. By logistic regression analysis, premenopausal status (odds ratio [OR][95% confidence interval {CI}] = 2.24 [1.30-3.87]), past hepatitis B virus (HBV) infections (OR [95% CI] = 4.23 [1.57-11.42]), liver metastasis (OR [95% CI] = 3.70 [2.16-6.34]). The predominant occurrence of DILI was seen in groups with docetaxel combination regimens. (OR [95% CI] = 2.66 [1.59-4.55]). The potential increasing occurrence of docetaxel-DILI was associated with multiple risk factors in an exposure-response manner (P < 0.001), and patients with more than three risk factors would be exposed to a 36.61-fold risk of DILI (95% CI = 10.18-131.62). Further analysis by the risk score and area under the receiver-operator characteristic curve (AUC) showed that those four factors contributed to an AUC of 0.7536 (95% CI = 0.70-0.81), with a predictive sensitivity of 74.63% and specificity of 65.17%. Docetaxel-DILI with a relatively higher incidence should be addressed among metastatic breast cancer patients. Four predominant risk factors, including premenopausal status, past HBV infection, liver metastasis, and docetaxel combination regimens, were potential predicators for DILI. © 2012 Journal of Gastroenterology and Hepatology Foundation and Blackwell Publishing Asia Pty Ltd.

    Alveolar soft-part sarcoma is a rare disease which has thus for been recognized as a malignant soft tissue tumor only with much uncertainty. This report describes a 29-year-old man with multiple cerebral metastasis of alveolar soft-part sarcoma, presumably originating in the retroperitoneum. He was admitted to our hospital with complaints of severe headache, nausea, and left homonymous hemianopsia. A CT scan showed a slight high-density area, with a marked peritumoral low density in the right occipital lobe. Vertebral angiography showed a tumor stain which appeared in the early arterial phase and lasted to the late venous one. Arteriovenous shunting was also remarkable. In the enhanced CT, a small high-density area was also noted in the left frontal lobe. Right occipital craniotomy was carried out, and a total removal was performed. Specimens of the tumor showed typical features of alveolar soft-part sarcoma histologically. Whole-brain radiotherapy-chemotherapy did not show any definite effect. A second operation for the left frontal tumor was carried out five months later. Histological and electron-microscopical examination again showed typical features of alveolar soft-part sarcoma. Regarding the choice of the treatment of this tumor, we recommended total removal of the tumor as the best management. (author)

    We report the case of a female patient who was referred to our unit because of a solid liver tumor, suggestive of metastasis. After biopsy, the patient was diagnosed with epithelioid hemangioendothelioma of the liver. Epithelioid hemangioendothelioma is a rare entity with an unpredictable, potentially fatal, clinical course and outcome. Due to its rarity, this entity should be considered when a solitary hepatic lesion is detected and should be included in the differential diagnosis with liver metastases. We highlight the infrequency of this tumor, its presentation as a solitary hepatic lesion and the indication of surgical treatment. We describe the clinical and pathological characteristics of epithelioid hemangioendothelioma of the liver and report a new case of this entity. The distinct therapeutic options are discussed.

Materials and methods: From 2010 to 2013, 245,707 breast cancer patients and 8901 patients diagnosed with initial bone metastasis were identified by Surveillance, Epidemiology, and End Results database of the National Cancer Institute. Multivariate logistic and Cox regression were used to identify predictive factors for the presence of bone metastasis and prognosis factors. Kaplan–Meier method and log-rank test were used for survival analysis. Results: Eight thousand nine hundred one patients with initial MBC had bone involvement, accounting for 3.6% of the entire cohort and 62.5% of the patients with initial MBC. Also, 70.5% of patients with bone metastasis were hormone receptor (HR positive (HR+/human epidermal growth factor receptor 2 [HER2]−: 57.6%; HR+/HER2+: 12.9%. Patients with initial bone metastasis had a better 5-year survival rate compared to those with initial brain, liver, or lung metastasis. HR+/HER2− and HR+/HER2+ breast cancer had a propensity of bone metastasis in the entire cohort and were correlated with better prognosis in patients with initial bone metastasis. Local surgery had significantly improved overall survival in initial MBC patients with bone metastasis. Conclusion: Our study has provided population-based estimates of epidemiologic characteristics and prognosis in patients with bone metastasis at the time of

    Full Text Available Acute liver failure (ALF is the culmination of severe liver cell injury from a variety of causes. ALF occurs when the extent of hepatocyte death exceeds the hepatic regenerative capacity. ALF has a high mortality that is associated with multiple organ failure (MOF and sepsis; however, the underlying mechanisms are still not clear. Emerging evidence shows that ALF patients/animals have high concentrations of circulating HMGB1, which can contribute to multiple organ injuries and mediate gut bacterial translocation (BT. BT triggers/induces systemic inflammatory responses syndrome (SIRS, which can lead to MOF in ALF. Blockade of HMGB1 significantly decreases BT and improves hepatocyte regeneration in experimental acute fatal liver injury. Therefore, HMGB1 seems to be an important factor that links BT and systemic inflammation in ALF. ALF patients/animals also have high levels of circulating histones, which might be the major mediators of systemic inflammation in patients with ALF. Extracellular histones kill endothelial cells and elicit immunostimulatory effect to induce multiple organ injuries. Neutralization of histones can attenuate acute liver, lung, and brain injuries. In conclusion, HMGB1 and histones play a significant role in inducing systemic inflammation and MOF in ALF.

    Objective: To analyze the correlations between liver lipid level determined by liver 3.0 T 1 H-MRS in vivo and influencing factors using multiple linear stepwise regression. Methods: The prospective study of liver 1 H-MRS was performed with 3.0 T system and eight-channel torso phased-array coils using PRESS sequence. Forty-four volunteers were enrolled in this study. Liver spectra were collected with a TR of 1500 ms, TE of 30 ms, volume of interest of 2 cm×2 cm×2 cm, NSA of 64 times. The acquired raw proton MRS data were processed by using a software program SAGE. For each MRS measurement, using water as the internal reference, the amplitude of the lipid signal was normalized to the sum of the signal from lipid and water to obtain percentage lipid within the liver. The statistical description of height, weight, age and BMI, Line width and water suppression were recorded, and Pearson analysis was applied to test their relationships. Multiple linear stepwise regression was used to set the statistical model for the prediction of Liver lipid content. Results: Age (39.1±12.6) years, body weight (64.4±10.4) kg, BMI (23.3±3.1) kg/m 2 , linewidth (18.9±4.4) and the water suppression (90.7±6.5)% had significant correlation with liver lipid content (0.00 to 0.96%, median 0.02%), r were 0.11, 0.44, 0.40, 0.52, -0.73 respectively (P<0.05). But only age, BMI, line width, and the water suppression entered into the multiple linear regression equation. Liver lipid content prediction equation was as follows: Y= 1.395 - (0.021×water suppression) + (0.022×BMI) + (0.014×line width) - (0.004×age), and the coefficient of determination was 0. 613, corrected coefficient of determination was 0.59. Conclusion: The regression model fitted well, since the variables of age, BMI, width, and water suppression can explain about 60% of liver lipid content changes. (authors)

  20. MiRNA-21 Expression Decreases from Primary Tumors to Liver Metastases in Colorectal Carcinoma.

    Full Text Available Metastasis is the major cause of death in colorectal cancer patients. Expression of certain miRNAs in the primary tumors has been shown to be associated with progression of colorectal cancer and the initiation of metastasis. In this study, we compared miRNA expression in primary colorectal cancer and corresponding liver metastases in order to get an idea of the oncogenic importance of the miRNAs in established metastases.We analyzed the expression of miRNA-21, miRNA-31 and miRNA-373 in corresponding formalin-fixed paraffin-embedded (FFPE tissue samples of primary colorectal cancer, liver metastasis and healthy tissues of 29 patients by quantitative real-time PCR.All three miRNAs were significantly up-regulated in the primary tumor tissues as compared to healthy colon mucosa of the respective patients (p < 0.01. MiRNA-21 and miRNA-31 were also higher expressed in liver metastases as compared to healthy liver tissues (p < 0.01. No significant difference of expression of miRNA-31 and miRNA-373 was observed between primary tumors and metastases. Of note, miRNA-21 expression was significantly reduced in liver metastases as compared to the primary colorectal tumors (p < 0.01.In the context of previous studies demonstrating increased miRNA-21 expression in metastatic primary tumors, our findings raise the question whether miRNA-21 might be involved in the initiation but not in the perpetuation and growth of metastases.

    2001-01-01

    Full Text Available In spite of intensive and increasingly successful attempts to determine the multiple steps involved in colorectal carcinogenesis, the mechanisms responsible for metastasis of colorectal tumors to the liver remain to be clarified. To identify genes that are candidates for involvement in the metastatic process, we analyzed genome-wide expression profiles of 10 primary colorectal cancers and their corresponding metastatic lesions by means of a cDNA microarray consisting of 9121 human genes. This analysis identified 40 genes whose expression was commonly upregulated in metastatic lesions, and 7 that were commonly downregulated. The upregulated genes encoded proteins involved in cell adhesion, or remodeling of the actin cytoskeleton. Investigation of the functions of more of the altered genes should improve our understanding of metastasis and may identify diagnostic markers and/or novel molecular targets for prevention or therapy of metastatic lesions.

    Many studies have been conducted on splenic thermal ablation for partial splenectomy hemostasis, spleen trauma, splenic metastasis and hypersplenism. In this article, we review the evolution and current status of radiofrequency and microwave ablation in the treatment of spleen diseases. All publications from 1990 to 2011 on radiofrequency and microwave ablation for partial splenectomy hemostasis, spleen trauma, splenic metastasis and hypersplenism were retrieved by searching PubMed. Thermal ablation in the spleen for partial splenectomy hemostasis, spleen trauma, splenic metastasis and hypersplenism can preserve part of the spleen and maintain splenic immunologic function. Thermal ablation for assisting hemostasis in partial splenectomy minimizes blood loss during operation. Thermal ablation for spleen trauma reduces the number of splenectomy and the amount of blood transfusion. Thermal ablation for splenic metastasis is minimally invasive and can be done under the guidance of an ultrasound, which helps shorten the recovery time. Thermal ablation for hypersplenism increases platelet (PLT) and white blood cell (WBC) counts and improves liver function. It also helps to maintain splenic immunologic function and even improves splenic immunologic function in the short-term. In conclusion, thermal ablative approaches are promising for partial splenectomy hemostasis, spleen trauma, splenic metastasis and hypersplenism. In order to improve therapeutic effects, directions for future studies may include standardized therapeutic indications, prolonged observation periods and enlarged sample sizes.

    Full Text Available Metastatic breast cancer (BC (also referred to as stage IV spreads beyond the breast to the bones, lungs, liver, or brain and is a major contributor to the deaths of cancer patients. Interestingly, metastasis is a result of stroma-coordinated hallmarks such as invasion and migration of the tumor cells from the primary niche, regrowth of the invading tumor cells in the distant organs, proliferation, vascularization, and immune suppression. Targeted therapies, when used as monotherapies or combination therapies, have shown limited success in decreasing the established metastatic growth and improving survival. Thus, novel therapeutic targets are warranted to improve the metastasis outcomes. We have been actively investigating the cytochrome P450 4 (CYP4 family of enzymes that can biosynthesize 20-hydroxyeicosatetraenoic acid (20-HETE, an important signaling eicosanoid involved in the regulation of vascular tone and angiogenesis. We have shown that 20-HETE can activate several intracellular protein kinases, pro-inflammatory mediators, and chemokines in cancer. This review article is focused on understanding the role of the arachidonic acid metabolic pathway in BC metastasis with an emphasis on 20-HETE as a novel therapeutic target to decrease BC metastasis. We have discussed all the significant investigational mechanisms and put forward studies showing how 20-HETE can promote angiogenesis and metastasis, and how its inhibition could affect the metastatic niches. Potential adjuvant therapies targeting the tumor microenvironment showing anti-tumor properties against BC and its lung metastasis are discussed at the end. This review will highlight the importance of exploring tumor-inherent and stromal-inherent metabolic pathways in the development of novel therapeutics for treating BC metastasis.

    We report a rare case of intractable bile leakage after liver resection due to stenosis of the anastomosis of a choledochojejunostomy after pancreaticoduodenectomy. A 65-year-old woman was diagnosed with pancreatic and right breast cancer, and underwent pancreaticoduodenectomy and right mastectomy with simultaneous axillary lymph node dissection. Adjuvant chemotherapy and follow-up were performed in our department. After 18 months, computed tomography revealed a liver metastasis of 2.5 cm in segment 8. Because the primary nest of liver metastasis was unknown and performing a biopsy was difficult due to the location, partial resection of the liver was performed. Pathological examination confirmed liver metastasis from the breast cancer. She was rehospitalized due to a right subdiaphragmatic abscess 33 days post-surgery. Abscess drainage revealed bile leakage, and the cause was believed to be stenosis of the anastomosis created by the choledochojejunostomy. Percutaneous transhepatic cholangiographic drainage was performed, and the bile leakage disappeared immediately. However, it was difficult to release the anastomotic stenosis by choledochoscopy; therefore, a retrograde drainage tube was placed in the hepatic duct using enteroscopy, and it formed an internal fistula. The patient has continued to undergo chemotherapy for recurrence in the remnant liver that was observed 16 months after the hepatectomy. In conclusion, when hepatic resection is performed after pancreaticoduodenectomy, attention should be paid to the possible occurrence of bile leakage.

    Hepatocellular carcinoma (HCC) is the most common primary liver cancer and often forms metastases, which are the most important prognostic factors. For further elucidation of the mechanism underlying the progression and metastasis of HCC, a culture system mimicking the in vivo tumor microenvironment is needed. In this study, we investigated the metastatic ability of HCC cells cultured within alginate gel (ALG) beads. In the culture system, HCC cells formed spheroids by proliferation and maintained in nuclear abnormalities. The gene and protein expression of metastasis-related molecules was increased in ALG beads, compared with the traditional adhesion culture. Furthermore, several gene expression levels in ALG bead culture system were even closer to liver cancer tissues. More importantly, in vitro invasion assay showed that the invasion cells derived from ALG beads was 7.8-fold higher than adhesion cells. Our results indicated that the in vitro three-dimensional (3D) model based on ALG beads increased metastatic ability compared with adhesion culture, even partly mimicked the in vivo tumor tissues. Moreover, due to the controllable preparation conditions, steady characteristics and production at large-scale, the 3D ALG bead model would become an important tool used in the high-throughput screening of anti-metastasis drugs and the metastatic mechanism research. -- Highlights: •We established a 3D metastasis model mimicking the metastatic ability in vivo. •The invasion ability of cells derived from our model was increased significantly. •The model is easy to reproduce, convenient to handle, and amenable for large-scale

    During chemotherapy in patients with gastrointestinal malignancy, the hepatic lesions may occur as chemotherapy-induced lesions or tumor-associated lesions, with exceptions for infectious conditions and other incidentalomas. Focal hepatic lesions arising from chemotherapy-induced hepatopathies (such as chemotherapy-induced sinusoidal injury and steatosis) and tumor-associated eosinophilic abscess should be considered a mimicker of metastasis in patients with gastrointestinal malignancy. Accumulating evidence suggests that chemotherapy for gastrointestinal malignancy in the liver has roles in both the therapeutic effects for hepatic metastasis and injury to the non-tumor bearing hepatic parenchyma. In this article, we reviewed the updated concept of chemotherapy-induced hepatopathies and tumor-associated eosinophilic abscess in the liver, focusing on the pathological and radiological findings. Awareness of the causative chemo-agent, pathophysiology, and characteristic imaging findings of these mimickers is critical for accurate diagnosis and avoidance of unnecessary exposure of the patient to invasive tissue-based diagnosis and operation.

Treatment with the PHD inhibitor DMOG in an orthotopic breast cancer model significantly decreases spontaneous metastases to the lungs and liver, associated with decreased tumour stiffness and fibroblast activation. PHD2 depletion in CAFs co......-injected with tumour cells similarly prevents CAF-induced metastasis to lungs and liver. Our data argue that reversion of CAFs towards a less active state is possible and could have important clinical implications....

    To assess parenchymal bolus-triggering in terms of liver enhancement, lesion-to-liver conspicuity and inter-image variability across serial follow-up MDCTs. We reviewed MDCTs of 50 patients with hepatic metastases who had a baseline CT and two follow-up examinations. In 25 consecutive patients CT data acquisition was initiated by liver parenchyma triggering at a 50-HU enhancement threshold. In a matched control group, imaging was performed with an empirical delay of 65 s. CT attenuation values were assessed in vessels, liver parenchyma and metastasis. Target lesions were classified according to five enhancement patterns. Compared with the control group, liver enhancement was significantly higher with parenchyma triggering (59.8 ± 7.6 HU vs. 48.8 ± 11.2 HU, P = 0.0002). The same was true for conspicuity (liver parenchyma - lesion attenuation) of hypo-enhancing lesions (72.2 ± 15.9 HU vs. 52.7 ± 19.4 HU, P = 0.0006). Liver triggering was associated with reduced variability for liver enhancement among different patients (P = 0.035) and across serial follow-up examinations in individual patients (P < 0.0001). The number of patients presenting with uniform lesion enhancement pattern across serial examinations was significantly higher in the triggered group (20 vs. 11; P = 0.018). Liver parenchyma triggering provides superior lesion conspicuity and improves standardisation of image quality across follow-up examinations with greater uniformity of enhancement patterns. (orig.)

    Purpose: To evaluate the effects of leaf with or without interdigitation in multiple brain metastasis volumetric modulated arc therapy (VMAT) plans. Methods: Twenty patients with 2 to 6 brain metastases of our hospital were retrospectively studied to be planned with dual arc VMAT using Monaco 3.3 TPS on the Elekta Synergy linear accelerator. The prescription dose of PTV was 60Gy/30 fractions. Two plans with or without leaf interdigitation were designed. The homogeneity index (HI), conformity index (CI), dose volume histograms (DVHs), monitor unit (MU), treatment time (T), the segments, the dose coverage of the target, were all evaluated. Results: The plans with leaf interdigitation could achieve better CI (p<0.05) than without leaf interdigitation, while no significant difference were found in HI (p> 0.05) and the dose coverage of the target (p> 0.05).The MU,T, and the segments of the plan with leaf interdigitation were more than the plan without leaf interdigitation (p<0.05). There was no significant difference found in radiation dose of spinal cord, lenses and parotids, while the maximum dose of brain stem of leaf without interdigitation was higher than leaf with interdigitation (p< 0.05). It was worth noting that the areas of low dose regions with leaf interdigitation plan were much less than the without leaf interdigitation plan in the doublication planes (p< 0.05). Conclusion: This study shows that leaf with interdigitation has some advantages than leaf without interdigitation in multiple brain metastasis VMAT plans although the clinical relevance remains to be proven.

    The treatment of hepatic metastasis of colon cancer was in progress by new biochemical agents. Generally, a resection was the first alternative treatment against hepatic metastasis of colon cancer, but new antitumor agents were more effective than conventional antitumor agents. Disappearance of metastasis for colon cancer treated with only antitumor agents was commenced to report. We were experienced a case of transverse colon cancer without a recurrence lesion after five years from the resection of hepatic metastasis. A case was a 77-year-old man. He was operated against transverse colon cancer in February 2003. Pathological stage was ss, n0, Stage II. In April 2004, serum CEA was increased. CT examination was not detected a hepatic metastasis but ultrasound examination and MRI detected the metastasis at S7 lesion in the liver. In July 2004, he was admitted to S-1 and PSK until October 2004. In December 2004, the lesion of hepatic metastasis was reduced and serum CEA was decreased. But in September 2005, the metastatic lesion was re-grown. A resection for hepatic metastasis was executed in November 2005. After the resection for hepatic metastasis, he was admitted to UFT/ UZEL from January 2006 to October 2006.

    Full Text Available We report a unique case of combined primary neuroendocrine carcinoma (NEC and hepatocellular carcinoma (HCC of the liver in a 65-year-old male patient. The patient underwent segmental resection of the liver and regional lymph node dissection for a tumor mass that measured 7.5 cm in diameter in the right lobe, with regional lymphadenopathy. Histologically, the hepatic tumor was composed of predominantly small-cell NEC, but admixed with a small island of moderately differentiated HCC. We speculate that the NEC originated from a poorly differentiated tumor clone of an HCC that underwent neuroendocrine differentiation, and that this tumor was now at the end stage of the transitional period from HCC to NEC, based on the small amount of disappearing HCC. Ki-67 and p53 expression were higher in the NEC than in the HCC, and the lymph nodes showed only metastatic NEC. Therefore, this kind of tumor had a more aggressive clinical course in accordance with being an NEC rather than a conventional HCC. Three months after operation, the patient had multiple recurrent tumor nodules within the liver, spreading the metastasis to the adrenal glands and para-aortic lymph nodes. The patient died 1 year after operation.

    Streptococcus salivarius is an oral commensal bacterium that rarely causes disease in humans. Here, we report a case of liver abscess associated with S. salivarius in a 41-year-old woman who presented with continuous abdominal discomfort, fatigue, and fever. She was diagnosed with multiple liver abscesses; she underwent percutaneous transhepatic abscess drainage. Thereafter, S. salivarius was isolated in all bacterial cultures of the drained abscesses, and it was sensitive to penicillins. She made a good recovery after treatment. In the absence of an infective source other than chronic periodontitis, the cause of liver abscesses was attributed to oral S. salivarius. S. salivarius is a normal oral commensal, and oral commensals must be considered if the infective origin of liver abscess cannot be determined.

  15. The Role of Extracellular Vesicles in Bone Metastasis

    Full Text Available Multiple types of cancer have the specific ability to home to the bone microenvironment and cause metastatic lesions. Despite being the focus of intense investigation, the molecular and cellular mechanisms that regulate the metastasis of disseminated tumor cells still remain largely unknown. Bone metastases severely impact quality of life since they are associated with pain, fractures, and bone marrow aplasia. In this review, we will summarize the recent discoveries on the role of extracellular vesicles (EV in the regulation of bone remodeling activity and bone metastasis occurrence. Indeed, it was shown that extracellular vesicles, including exosomes and microvesicles, released from tumor cells can modify the bone microenvironment, allowing the formation of osteolytic, osteosclerotic, and mixed mestastases. In turn, bone-derived EV can stimulate the proliferation of tumor cells. The inhibition of EV-mediated crosstalk between cancer and bone cells could represent a new therapeutic target for bone metastasis.

    Gangliocytic paraganglioma (GP) is a rare benign neuroendocrine tumour found most often in the duodenum. To our knowledge, only a dozen cases of possibly malignant duodenal GP with local lymph node metastasis and only one case with liver metastasis have previously been published. Herein, we report...... an unusual case of GP of the duodenum spreading to the retropancreatic space and metastatic to the liver and lymph nodes. Additionally, the present tumour secreted pancreatic polypeptide (PP) which was detected in the serum during the follow-up period. We suggest that serum PP could be a valuable marker...

    Focal fatty infiltration of the liver is an entity that may be confused with liver metastasis on computed tomography (CT). The imaging results and medical records of 16 patients with CT appearance suggestive of focal fatty liver were reviewed, three of whom had the simultaneous presence of metastitic liver disease. Focal fatty liver often has a distinctive appearance with CT, usually with a nonspherical shape, absence of mass effect, and density close to water. Liver metastases are usually round or oval, and unless cystic or necrotic, they have CT attenuation values closer to normal liver parenchyma than water. A radionuclide liver scan almost always resolves any confusion about the differential diagnosis of focal fatty liver: a well defined focus of photon deficiency is due to neoplasm rather than focal fatty infiltration. Sonography sometimes helps to confirm the CT impression, but may be misleading if the diagnosis of focal or diffuse fatty infiltration is not suspected before the examination

    Paragangliomas are rare neuroendocrine tumors of neural crest origin. They are mostly benign, however; malignant tumors with aggressive behavior and distant metastasis can also occur. Intracranial involvement is extremely rare and has been sporadically reported in the literature. Here we report a case who presented with progressive neurologic deficits due to multiple intracranial lesions found to be metastasis from an occult retroperitoneal malignant paraganglioma.

    Full Text Available Uveal melanoma is a rare malignancy. Its clinical course is highly agressive. At thetime of diagnosis, extraocular extension is present in most of the cases.We present a case of 69-year-old white man admitted for sharp orbital pain. Advanced uveal melanoma was diagnosed. We found black-colored tumor rotruding from the left eye and multiple cutaneous metastases on the scalp. CT scan revealed intracranial tumor mimicking meningeoma in the left parietal region. Lymhogenous metastases were not found and other hematogenous metastases were excluded. After biopsy of the eye tumor and excisional biopsy of one skin tumor, the uveal melanoma was diagnosed and the left orbital exenteration and extirpation of intracranial tumor were performed. The reconstruction was performed using galeacutaneous flap harvested from craniotomy flap. Postoperative course was uneventful and the patient was released from pain. He refused the additional oncological treatment. After four months, he died of liver metastatic disease.The uveal melanoma is highly aggressive malignancy and isolated subdural metastasis is quite rare. The reconstruction with transposed galeacutaneous flap is versatile and secure technique after orbital exenteration.

    MACC1 (Metastasis Associated in Colon Cancer 1) is a key driver and prognostic biomarker for cancer progression and metastasis in a large variety of solid tumor types, particularly colorectal cancer (CRC). However, no MACC1 inhibitors have been identified yet. Therefore, we aimed to target MACC1 expression using a luciferase reporter-based high-throughput screening with the ChemBioNet library of more than 30,000 compounds. The small molecules lovastatin and rottlerin emerged as the most potent MACC1 transcriptional inhibitors. They remarkably inhibited MACC1 promoter activity and expression, resulting in reduced cell motility. Lovastatin impaired the binding of the transcription factors c-Jun and Sp1 to the MACC1 promoter, thereby inhibiting MACC1 transcription. Most importantly, in CRC-xenografted mice, lovastatin and rottlerin restricted MACC1 expression and liver metastasis. This is-to the best of our knowledge-the first identification of inhibitors restricting cancer progression and metastasis via the novel target MACC1. This drug repositioning might be of therapeutic value for CRC patients.

    High-output cardiac failure is associated with several systemic illnesses, including hyperthyroidism, thiamine deficiency, severe anemia, multiple myeloma, Paget's disease of bone and Osler-Weber-Rendu syndrome. We present an unusual case of a woman with high-output cardiac failure as a result of multiple arteriovenous fistulas in the liver, most likely representing an unusual variant of Osler-Weber-Rendu syndrome (i.e., no other telangiectasias or a family history of vascular malformations was demonstrated).

    The hepatic microenvironment, which may include chronic inflammation and fibrosis, is considered to contribute to the pathogenesis of liver metastases of colorectal cancer. A similar mechanism is anticipated for pulmonary metastases, although no reports are available. Smoking causes pulmonary inflammation and fibrosis. Thus, we hypothesized that smokers would be especially affected by pulmonary metastases of colorectal cancer. In this study, we attempted to clarify the impact of smoking on pulmonary metastasis of colorectal cancer. Between September 2005 and December 2010 we reviewed 567 patients with pathological Stage I, II or III colorectal cancer, whose clinicopathological background included a preoperative smoking history, pack-year history from medical records. Univariate and multivariate analyses using the Cox proportional hazard model were performed to determine the independent prognostic factors for pulmonary metastasis-free survival. Pulmonary metastases occurred in 39 (6.9%) patients. The smoking histories revealed 355 never smokers, 119 former smokers and 93 current smokers among the subjects. Multivariate analysis revealed that being a current smoker (hazard ratio = 2.72, 95% CI 1.18-6.25; P = 0.02) was an independent risk factor for pulmonary metastases. Smoking may be a risk factor for pulmonary metastasis of colorectal cancer. Cessation of smoking should be recommended to prevent pulmonary metastasis, although further basic and clinical studies are required.

    Full Text Available Tuberculosis (TB presenting as isolated liver mass without clinical evidence of TB is difficult to diagnose preoperatively and is usually mimicked by primary or metastatic carcinoma of the liver. Hepatic TB associated with carcinoma colon is a rare association which has very rarely been reported in the literature. This case illustrates the diagnostic difficulties of hepatic TB and the need to consider it in the differential diagnosis of hepatic nodular lesions in carcinoma colon patients. Here, we report a case of 48-year-old female who presented in the casualty with features of acute intestinal obstruction. Preoperatively a mass was seen at the hepatic flexure along with three lesions in the liver presumed to be metastatic in origin. However, histopathology of the mass revealed adenocarcinoma colon and the liver lesion proved to be hepatic TB. We wish to highlight that on encountering a hepatic lesion in a carcinoma colon patient the possibility of hepatic TB should also be kept in mind apart from the obvious possibility of metastasis especially in an endemic country like India.

    A 48-year-old woman with invasive ductal carcinoma of the left breast underwent breast-conserving surgery and axillary dissection; 19 months after surgery, she developed local recurrence. Subsequently, she underwent mastectomy and received endocrine therapy and chemotherapy. At 47 years of age, she developed pleural metastasis, which directly invaded the vertebrae as well as the right supraclavicular and right axillary lymph nodes. In addition, liver metastasis was observed. To avoid acute transverse myelopathy, the patient received radiation therapy to the vertebrae and the right supraclavicular and right axillary lymph nodes followed by paclitaxel plus bevacizumab administration. After 2 courses of paclitaxel plus bevacizumab, we observed a remarkable shrinkage of the vertebral tumor, and skin necrosis was observed in the right supraclavicular and right axillary region; in contrast, the liver metastasis had increased in size. After discontinuation of the combination therapy, the patient died of blood loss from the axillary skin defect. This wound healing complication might have arisen because of the synergistic effects of paclitaxel plus bevacizumab and irradiation. (author)

    During the proliferation and metastasis, the tumor cells prefer glycolysis (Warburg effect), but its exact mechanism remains largely unknown. In this study, we demonstrated that phosphoglycerate kinase 1 (PGK1) is an important enzyme in the pathway of metabolic glycolysis. We observed a significant overexpression of PGK1 in hepatocellular carcinoma tissues, and a correlation between PGK1 expression and poor survival of hepatocellular carcinoma patients. Also, the depletion of PGK1 dramatically reduced cancer cell proliferation and metastasis, indicating an oncogenic role of PGK1 in liver cancer progression. Further experiments showed that PGK1 played an important role in MYC -induced metabolic reprogramming, which led to an enhanced Warburg effect. Our results revealed a new effect of PGK1, which can provide a new treatment strategy for hepatocellular carcinoma, as PGK1 is used to indicate the prognosis of hepatocellular carcinoma (HCC).

    To systematically explore the molecular mechanism for hepatocellular carcinoma (HCC) metastasis and identify regulatory genes with text mining methods. Genes with highest frequencies and significant pathways related to HCC metastasis were listed. A handful of proteins such as EGFR, MDM2, TP53 and APP, were identified as hub nodes in PPI (protein-protein interaction) network. Compared with unique genes for HBV-HCCs, genes particular to HCV-HCCs were less, but may participate in more extensive signaling processes. VEGFA, PI3KCA, MAPK1, MMP9 and other genes may play important roles in multiple phenotypes of metastasis. Genes in abstracts of HCC-metastasis literatures were identified. Word frequency analysis, KEGG pathway and PPI network analysis were performed. Then co-occurrence analysis between genes and metastasis-related phenotypes were carried out. Text mining is effective for revealing potential regulators or pathways, but the purpose of it should be specific, and the combination of various methods will be more useful.

    Thymosin β10 (Tβ10) expression is associated with malignant phenotypes in many cancers. However, the role and mechanisms of Tβ10 in liver fluke-associated cholangiocarcinoma (CCA) are not fully understood. In this study, we investigated the expression of Tβ10 in CCA tumor tissues and cell lines as well as molecular mechanisms of Tβ10 in tumor metastasis of CCA cell lines. Tβ10 expression was determined by real time RT-PCR or immunocytochemistry. Tβ10 silence or overexpression in CCA cells was achieved using gene delivery techniques. Cell migration was assessed using modified Boyden chamber and wound healing assay. The effect of silencing Tβ10 on CCA tumor metastasis was determined in nude mice. Phosphorylation of ERK1/2 and the expression of EGR1, Snail and matrix metalloproteinases (MMPs) were studied. Ten pairs of CCA tissues (primary and metastatic tumors) and 5 CCA cell lines were studied. With real time RT-PCR and immunostaining analysis, Tβ10 was highly expressed in primary tumors of CCA; while it was relatively low in the metastatic tumors. Five CCA cell lines showed differential expression levels of Tβ10. Silence of Tβ10 significantly increased cell migration, invasion and wound healing of CCA cells in vitro; reversely, overexpression of Tβ10 reduced cell migration compared with control cells (P<0.05). In addition, silence of Tβ10 in CCA cells increased liver metastasis in a nude mouse model of CCA implantation into the spleen. Furthermore, silence of Tβ10 activated ERK1/2 and increased the expression of Snail and MMPs in CCA cell lines. Ras-GTPase inhibitor, FPT inhibitor III, effectively blocked Tβ10 silence-associated ERK1/2 activation, Snail expression and cell migration. Low expression of Tβ10 is associated with metastatic phenotype of CCA in vitro and in vivo, which may be mediated by the activation of Ras, ERK1/2 and upregulation of Snail and MMPs. This study suggests a new molecular pathway of CCA pathogenesis and a novel strategy to

    2015-01-01

    Full Text Available Gallbladder cancer is a common malignancy in Northern India, and it accounts for 2-4% of all malignant gastrointestinal tumors. It is an aggressive tumor with early dissemination to liver and lymph nodes and associated with poor prognosis. Systemic metastases from gall bladder carcinoma (Ca frequently occur; however, metastatic involvement of the central nervous system is rare and late manifestation and remains an ominous sign. Initial presentation of gall bladder Ca with brain metastasis is rare. We report a case of 65-year-old women who initially presented with a solitary brain metastasis from an adenocarcinoma of the gallbladder, which was diagnosed incidentally when the patient presented with headache, vomiting, and right temporal region swelling. Palliative chemotherapy and cranial radiotherapy were prescribed. She is symptom-free from 3 months after the completion of the treatment.

    2016-01-01

    Renal cell carcinoma (RCC) – also known as hypernephroma or grawitz tumor – accounts for 3% of the adulthood malignancies. Approximately 30–40% of the patients have metastasis at the time of the diagnosis and most common sites for metastasis are lung, regional lymph nodes, bone and liver. A total of 8–14% of the patients with RCC has head and neck metastasis. However, metastasis to major salivary glands is rarely seen. In this paper, we aimed to report a RCC case with metastasis to parotid and submandibular glands that has the same sonographic and sonoelastographic findings with the primary tumor. 66-year old woman with RCC history was referred to our radiology department for neck ultrasound (US) with painful swelling in the right parotid gland region. A well-defined, 37×21 mm sized hypoechoic heterogeneous solid mass was detected in the superficial-deep lobe of the right parotid gland. The mass was prominently hypervascular in color Doppler ultrasonography scan. Coincidentally, a 13×13 mm hypoechoic lobulated solid mass was detected in the right submandibular gland with similar sonographic findings. Real-time sonoelastography (SEL) was performed to the masses and both of them were blue-green colored that indicates hard tissue. An US and SEL evaluation was also performed to the renal mass (RCC) of the patient. The primary mass was also similar in sonographic and SEL appearance as salivary gland masses. In the patient history, she revealed chemotherapy-radiotherapy treatment 1.5 years ago due to inoperable mass in the mid-lower pole of the left kidney diagnosed as clear cell RCC with vascular invasion, liver, lung and brain metastasis. Because of known primary tumor, the masses in the salivary glands were suspected to be metastatic and a tru-cut biopsy was performed. Pathological result was reported as clear cell RCC metastasis. The etiology of RCC is still unknown and metastatic involvement can be seen at unexpected tissue and organs. Metastatic disease

    Due to the high incidence of local recurrence and liver metastasis, long-term outcomes for patients after resection of pancreatic cancer are extremely poor. For improving the survival of the patients, a combination of preoperative chemoradiation, surgery, and postoperative liver-perfusion chemotherapy (LPC) were performed. Postoperative histopathologic study revealed a marked degenerative change in cancer tissue, showing negative surgical margins (R0) in 98% of patients and negative nodal involvement in 85% of patients. The 5-year survival rate after pancreatectomy was 56%, with low incidences of both local recurrence (11%) and liver metastasis (9%). This combination therapy were able to effectively reduce the incidence of both local and liver recurrence and improved long-term outcomes for patients with T3-4 cancers of the pancreas. (author)

  15. Metformin: An Emerging New Therapeutic Option for Targeting Cancer Stem Cells and Metastasis

    Directory of Open Access Journals (Sweden)

    Ramandeep Rattan

    2012-01-01

    Full Text Available Metastasis is an intricate process by which a small number of cancer cells from the primary tumor site undergo numerous alterations, which enables them to form secondary tumors at another and often multiple sites in the host. Transition of a cancer cell from epithelial to mesenchymal phenotype is thought to be the first step in the progression of metastasis. Recently, the recognition of cancer stem cells has added to the perplexity in understanding metastasis, as studies suggest cancer stem cells to be the originators of metastasis. All current and investigative drugs have been unable to prevent or reverse metastasis, as a result of which most metastatic cancers are incurable. A potential drug that can be considered is metformin, an oral hypoglycemic drug. In this review we discuss the potential of metformin in targeting both epithelial to mesenchymal transition and cancer stem cells in combating cancer metastases.

    Postoperative recurrence and metastasis are the major problems for the current treatment of hepatocellular carcinomas (HCC) in the clinic, including hepatectomy and liver transplantation. Here, we report that arsentic-loaded nanoparticles (ALNPs) are able to reduce the invasion of HCC cells in vitro, and, more importantly, can strongly suppress the invasion and metastasis of HCC in vivo without adverse side effects. Compared to free drug arsenic trioxide , ALNPs can deliver the drug into cancer cells more efficiently, destroy the structure of microtubules and reduce the aggregation of microfilaments in cell membranes more significantly. Furthermore, our results also reveal that tumor cells in murine blood were reduced remarkably after intravenous injection of ALNPs, indicating that this nano-drug may efficiently kill circulating tumor cells in vivo. In conclusion, our nano-drug ALNPs have great potential for the suppression of metastasis of HCC, which may open up a new avenue for the effective treatment of HCC without metastasis and recurrence.

    Full Text Available Abstract Background Angiogenesis is one of the mechanisms most critical to the postoperative recurrence and metastasis of hepatocellular carcinoma (HCC. Thus, finding the molecular markers associated with angiogenesis may help identify patients at increased risk for recurrence and metastasis of HCC. This study was designed to investigate whether CD105 or CD34 could serve as a valid prognostic marker in patients with HCC by determining if there is a correlation between CD105 or CD34 expression and postoperative recurrence or metastasis. Methods Immunohistochemical staining for the CD105, CD34 and vascular endothelial growth factor (VEGF antibodies was performed in 113 HCC tissue specimens containing paracarcinomatous tissue and in 14 normal liver tissue specimens. The quantitation of microvessels identified by anti-CD105 and anti-CD34 monoclonal antibodies and the semiquantitation of VEGF expression identified by anti-VEGF monoclonal antibody were analyzed in conjunction with the clinicopathological characteristics of the HCC and any available follow-up information about the patients from whom the specimens were obtained. Results CD105 was not expressed in the vascular endothelial cells of any normal liver tissue or paracarcinomatous liver tissue but was expressed in the vascular endothelial cells of all HCC tissue. In contrast, CD34 was expressed in the vascular endothelial cells of normal liver tissue, paracarcinomatous tissue, and HCC tissue in the following proportions of specimens: 86.7%, 93.8%, and 100%, respectively. The microvascular densities (MVDs of HCC determined by using an anti-CD105 mAb (CD105-MVD and an anti-CD34 mAb (CD34-MVD, were 71.7 ± 8.3 (SD and 106.3 ± 10.4 (SD, respectively. There was a significant correlation between CD105-MVD and CD34-MVD (r = 0.248, P = 0.021. Although CD34-MVD was significantly correlated with VEGF expression (r = 0.243, P = 0.024, CD105-MVD was more closely correlated (r = 0.300, P= 0.005. The

    In carrying out bone scintigraphy in 224 cases over the 5 years from June, 1978 to May, 1983 as a part of the post-treatment management of cervical carcinoma. Bone metastases were seen in 12.5% (28 cases) of the subjects, about 6% of the total post-treatment cases of cervical carcinoma in the corresponding period (466 cases). Bone metastases were seen in 9.3% (16/172) of post-operative cases, compared with 23.1% (12/52) of non-operative cases. Bone metastases were not seen in clinical stages Ia through IIa (49 cases) but were seen in IIb or higher stages. Bone metastasis rates by histological type, according to WHO classification, were 12.8% (26/203) in squamous cell carcinoma, 5.9% (1/17) in adenocarcinoma, and 25% (1/4) in adenosquamous carcinoma. Among the squamous cell carcinoma cases, small cell non-keratinizing type had the highest bone metastasis rate. Of 172 post-operative cases, 20.8% (11/53) of those with lymph node metastasis exhibited bone metastasis, higher than the 4.2% (5/119) in cases without lymph node metastasis. As to CPL classification, bone metastasis was seen more often in L type (18.8%) than C(0.0%) or P types (6.6%). Our risk classification of 168 cases demonstrated that bone metastasis was not seen in risk I group (74 cases), but was seen in 6.7% (1/17) of risk II group and in 19.0% (15/79) of risk III group. Twenty-eight cases with bone metastasis included 11 cases with local recurrence, 8 with pulmonary metastases, 4 with hepatic metastases and 4 with Virchow's lymphnode metastases. The 28 bone metastasis cases included 10 cases with multiple bone metastases and 5 with only a single bone metastasis. Most bone metastases were seen in the lumbar vertebrae and the pelvic bone. Post-operative cases had more distant metastases than non-operative cases. On diagnosis of bone metastases and 17 of the 28 patients had pain, 6 of the remaining 11 patients developing pain thereafter. (J.P.N.).

    The classification of liver lesions is often problematic in particular if they are multiple and show an heterogeneous shape. Here we report of a young patient with multiple liver lesions of up to 3 cm size. Using ultrasound, the lesions were hyper-, hypoechogen or mixed. In serial contrast enhanced CT scans some of the lesions showed the typical enhancement pattern of hemangiomas, however, the diagnosis could still not be faithfully determined for all lesions. Therefore, the patient was conducted to contrast enhanced MRI (Gd-DTPA and MnDPDP). While with Gd-DTPA some of the lesions showed a strong enhancement, they remained hypointense after administration of MnDPDP. Finally to exclude a metastatic disease a {sup 99m}Tc-erythrocyte SPECT was performed confirming the diagnosis of hemangiomas for most of the lesions. Diagnosis was not assessed by biopsy because this would only clarify the diagnosis for one or few of the lesions. The patient was subsequently followed up for 3 years and all lesions remained unchanged. This case clearly illustrates the difficulty to get a certain diagnosis of multiple liver lesions with heterogeneous appearance despite the multimodal diagnostic conduct. (orig.) [German] Bei einer Routineuntersuchung wurden bei einem jungen Patienten sonographisch multiple Leberrundherde mit hyper-, hypoechogener und gemischter Echogenitaet detektiert. Auch mittels triphasischer kontrastmittelverstaerkter CT gelang nur bei einem Teil der Herde die Einstufung als Haemangiome anhand ihres Irisblendenphaenomens. MRT-Untersuchungen unter Verwendung von Gd-DTPA und MnDPDP wurden angeschlossen. Mit Gd-DTPA zeigten einige Herde ein kraeftiges Enhancement, unter Verwendung von MnDPDP jedoch blieben sie hypointens. Auf eine Biopsie wurde verzichtet, da diese nur bei einem oder wenigen Herden die Diagnose liefern wuerde, die anderen Herde aber unter Beruecksichtigung ihrer Heterogenitaet unklar geblieben waeren.

  20. Tumour metastasis-associated gene profiling using one-dimensional microfluidic beads array

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Great efforts have been made on the early diagnosis and molecular mechanism research of tumour metastasis in recent years. In this paper, based on the one-dimensional microfluidic beads array, a novel platform for tumour metastasis-associated genes profiling has been developed by depositing nucleic acids functional beads in the microchannel. This platform is sensitive (limit of detection: 0.02 nmol/L) and can perform mRNAs analysis without PCR. Two human colon cancer cell lines (primary and metastatic) from the same patient were used as a model, and transcriptional expression profiling of multiple tumour metastasis-associated genes in these two cell lines was successfully achieved. Furthermore, the results obtained on the beads array were validated by RT-PCR. This novel beads array has advantages of high sensitivity, little sample consumption, short assay time, low cost and high throughput capability. It holds the potential in early diagnosis and mechanism research of tumour metastasis.

  1. Surgical treatment of pancreatic endocrine tumors in multiple endocrine neoplasia type 1

    Marcel Cerqueira Cesar Machado

    Full Text Available Surgical approaches to pancreatic endocrine tumors associated with multiple endocrine neoplasia type 1 may differ greatly from those applied to sporadic pancreatic endocrine tumors. Presurgical diagnosis of multiple endocrine neoplasia type 1 is therefore crucial to plan a proper intervention. Of note, hyperparathyroidism/multiple endocrine neoplasia type 1 should be surgically treated before pancreatic endocrine tumors/multiple endocrine neoplasia type 1 resection, apart from insulinoma. Non-functioning pancreatic endocrine tumors/multiple endocrine neoplasia type 1 >1 cm have a high risk of malignancy and should be treated by a pancreatic resection associated with lymphadenectomy. The vast majority of patients with gastrinoma/multiple endocrine neoplasia type 1 present with tumor lesions at the duodenum, so the surgery of choice is subtotal or total pancreatoduodenectomy followed by regional lymphadenectomy. The usual surgical treatment for insulinoma/multiple endocrine neoplasia type 1 is distal pancreatectomy up to the mesenteric vein with or without spleen preservation, associated with enucleation of tumor lesions in the pancreatic head. Surgical procedures for glucagonomas, somatostatinomas, and vipomas/ multiple endocrine neoplasia type 1 are similar to those applied to sporadic pancreatic endocrine tumors. Some of these surgical strategies for pancreatic endocrine tumors/multiple endocrine neoplasia type 1 still remain controversial as to their proper extension and timing. Furthermore, surgical resection of single hepatic metastasis secondary to pancreatic endocrine tumors/multiple endocrine neoplasia type 1 may be curative and even in multiple liver metastases surgical resection is possible. Hepatic trans-arterial chemo-embolization is usually associated with surgical resection. Liver transplantation may be needed for select cases. Finally, pre-surgical clinical and genetic diagnosis of multiple endocrine neoplasia type 1 syndrome and

    1999-01-01

    To investigate the role of beta1 integrin during tumor metastasis, we established a ras-myc transformed fibroblastoid cell line with a disrupted beta1 integrin gene on both alleles (GERM 11). Stable transfection of this cell line with an expression vector encoding beta1A integrin resulted in beta1A......, tumors induced by the high expressing clones 1A10 and 2F2 were markedly smaller, suggesting an inverse correlation of tumor growth and beta1 integrin expression. The metastasis potential of all three beta1 integrin-expressing GERM 11 sublines tested was significantly higher than that of the beta1......-deficient GERM 11 cells. GERM 116 tumors led in all animals to severe metastasis in lung and liver, while GERM 11 tumors induced only a few metastatic foci in the lung. Stroma of both tumors contained nidogen and high amounts of tenascin C, but only a few very low levels of fibronectin, laminin-1...

    The aim of the study was to investigate whether RCC patients with oligometastatic state of bone metastasis treated with sunitinib had a favorable clinical outcome. 22 patients were classified into oligometastatic state of bone metastasis with a median OS of 30.1 months (95%CI: 26.3 to 33.8 months). The 45 patients with non-oligometastatic state had a median OS of 12.7 months (95%CI: 9.43 to 16.0 months). Kaplan-Meier analysis showed significant difference between them (Log Rank test p<0.001). When we set patients with only multiple bone (at least 5 sites) metastases as a single group, there was still significant difference between oligometastatic state group and non-oligometastatic state groups. In multivariate Cox proportion hazard ratio analysis, metastatic states (p=0.012), MSKCC score (p=0.002), ECOG (p=0.001) and lymph nodes metastasis (p=0.000) were significantly associated with prognosis. The integration of metastatic state into the MSKCC risk model improved the c-index from 0.651 to 0.752. 67 patients from Fudan University Shanghai Cancer Center with bone metastatic RCC were divided into 2 metastatic states. One included those with oligometastatic state of bone metastasis with less than 5 sites of bone metastasis. The other involved those patients with multiple bone metastases (at least 5 sites) or together with other sites of metastasis. Then patients with only multiple bone (at least 5 sites) metastases were set into a single group. RCC patients with oligometastatic state of bone metastasis treated with sunitinib had a favorable clinical outcome.

  4. Liver metastasis from neuroendocrine carcinoma after the use of the new direct-action antivirals against hepatitis C virus in a patient with past history of hepatocellular carcinoma

    Directory of Open Access Journals (Sweden)

    María Caldas

    Full Text Available The use of the new direct-action antivirals against hepatitis C virus provides very high viral eradication rates. However, various recently published articles recommend caution with their use after the appearance of some cases of de novo tumors (originated in hepatic and extra-hepatic locations and a possible shorter time period of recurrence of hepatocellular carcinomas previously treated with surgery or loco-regional therapies. The sudden drop of the number of natural killer cells secondary to the use of these new medicines has been suggested as one of the possible mechanisms responsible for this process. However, due to the controversy concerning this subject and the absence of long-term follow-up studies in clinical practice, caution is needed before definitive conclusions are settled. We present the case report of a patient diagnosed of chronic liver disease secondary to hepatitis C virus infection and a past history of hepatocellular carcinoma in complete remission after radiofrequency ablation. He was treated with the new direct-action antivirals reaching sustained viral response. Six months later, the patient was diagnosed with liver metastasis from a small-cell neuroendocrine tumor of unknown primary site.

    Objective: To assess the diagnostic value of MRI on multiple focal nodular hyperplasia (FNH) of the liver. Methods: MR images of 9 cases with pathological-confirmed multiple FNH were retrospectively analyzed. MRI features of the lesions were correlated with pathological findings. Results: Multiple FNH was considered in all these 9 cases. Among them, the primary diagnosis was FNH in 5, hepatic adenoma in 3 and fibrolamellar hepatocellular carcinoma in 1 case. A total of 31 lesions were detected in the 9 cases. On T 2 WI, 19 lesions presented slightly high-signal intensity, and the other 12 presented iso-signal intensity. On T 1 WI, 12 lesions presented slightly low-signal intensity, 7 presented iso-signal intensity, and the other 12 presented high-signal intensity. On opposed-phase, the signal intensity of 1 lesion dropped unevenly. After bolus injection of contrast agent Gd-DTPA, in hepatic arterial phase 18 lesions showed mild to marked heterogeneous enhancement, 11 showed marked homogeneous enhancement, 1 showed moderate ring-like enhancement, and the last one did not have obvious enhancement. In portal venous and delayed phase, all the lesions turned to iso- or slightly high-signal intensity gradually. Sixteen of 31 lesions presented central scar, which demonstrated mild star-like enhancement in delayed phase. Conclusion: Multiple FNH presented certain MRI features, which contributed to the preoperative diagnosis. (authors)

    2013-04-01

    Full Text Available A five-year-old male Boerboel presented for examination, collapsed for an unknown period of time. On clinical examination, multifocal subcutaneous masses and enlarged prescapular lymph nodes as well as neurological deficits that suggested a multifocal neurological syndrome were found. Fine needle aspirates of the prescapular lymph nodes revealed cells suggestive of osteosarcoma. Radiographs showed foci of mineralisation within the soft tissue masses as well as diffuse pulmonary metastasis and a caudodorsal mediastinal mass believed to be a Spirocerca lupi nodule. Computed tomography imaging, necropsy and histopathology confirmed S. lupi oesophageal neoplastic transformation (extraskeletal osteosarcoma, believed to be the primary lesion, and the majority of secondary metastasis to the brain, spine, heart, multiple muscular groups and abdominal organs. This is the first known report of extraskeletal osteosarcoma metastasis to the brain and spinal cord in a dog.

    Full Text Available Targeted therapy based on adjustment of microRNA (miRNAs activity takes great promise due to the ability of these small RNAs to modulate cellular behavior. However, the efficacy of miR-101 replacement therapy to hepatocellular carcinoma (HCC remains unclear. In the current study, we first observed that plasma levels of miR-101 were significantly lower in distant metastatic HCC patients than in HCCs without distant metastasis, and down-regulation of plasma miR-101 predicted a worse disease-free survival (DFS, P<0.05. In an animal model of HCC, we demonstrated that systemic delivery of lentivirus-mediated miR-101 abrogated HCC growth in the liver, intrahepatic metastasis and distant metastasis to the lung and to the mediastinum, resulting in a dramatic suppression of HCC development and metastasis in mice without toxicity and extending life expectancy. Furthermore, enforced overexpression of miR-101 in HCC cells not only decreased EZH2, COX2 and STMN1, but also directly down-regulated a novel target ROCK2, inhibited Rho/Rac GTPase activation, and blocked HCC cells epithelial-mesenchymal transition (EMT and angiogenesis, inducing a strong abrogation of HCC tumorigenesis and aggressiveness both in vitro and in vivo. These results provide proof-of-concept support for systemic delivery of lentivirus-mediated miR-101 as a powerful anti-HCC therapeutic modality by repressing multiple molecular targets.

    PurposeTo investigate predictive factors for liver necrosis after transcatheter arterial chemoembolization (TACE) of neuroendocrine liver metastases.MethodsA total of 164 patients receiving 374 TACE were reviewed retrospectively to analyze predictive factors of liver necrosis. We analyzed patient age and sex; metastasis number and location; percentage of liver involvement; baseline liver function test; and pretreatment imaging abnormalities such as bile duct dilatation (BDD), portal vein narrowing (PVN), and portal vein thrombosis (PVT). We analyzed TACE technique such as Lipiodol or drug-eluting beads (DEB) as the drug’s vector; dose of chemotherapy; diameter of DEB; and number, frequency, and selectivity of TACE.ResultsLiver necrosis developed after 23 (6.1 %) of 374 TACE. In multivariate analysis, DEB > 300 μm in size induced more liver necrosis compared to Lipiodol (odds ratio [OR] 35.20; p < 0.0001) or with DEB < 300 μm in size (OR 19.95; p < 0.010). Pretreatment BDD (OR 119.64; p < 0.0001) and PVT (OR 9.83; p = 0.030) were predictive of liver necrosis. BDD or PVT responsible for liver necrosis were present before TACE in 59 % (13 of 22) and were induced by a previous TACE in 41 % (9 of 22) of cases.ConclusionDEB > 300 μm in size, BDD, and PVT are responsible for increased rate of liver necrosis after TACE. Careful analysis of BDD or PVT on pretreatment images as well as images taken between two courses can help avoid TACE complications.

    Diabetic patients are reported to have a high incidence and mortality of cancer, but little is known about the linkage. In this study, we investigated whether high oxidative stress is involved in the acceleration of tumor metastasis in diabetic mice. Murine melanoma B16-BL6 cells stably labeled with firefly luciferase (B16-BL6/Luc) were inoculated into the tail vein of streptozotocin (STZ)-treated or untreated mice. A luciferase assay demonstrated that tumor cells were present largely in the lung of untreated mice, whereas large numbers of tumor cells were detected in both the lung and liver of STZ-treated mice. Repeated injections of polyethylene glycol-conjugated catalase (PEG-catalase), a long-circulating derivative, reduced the elevated fasting blood glucose levels and plasma lipoperoxide levels of STZ-treated mice, but had no significant effects on these parameters in untreated mice. In addition, the injections significantly reduced the number of tumor cells in the lung and liver in both untreated and STZ-treated mice. Culture of B16-BL6/Luc cells in medium containing over 45 mg/dl glucose hardly affected the proliferation of the cells, whereas the addition of plasma of STZ-treated mice to the medium significantly increased the number of cells. Plasma samples of STZ-treated mice receiving PEG-catalase exhibited no such effect on proliferation. These findings indicate that a hyperglycemia-induced increase in oxidative stress is involved in the acceleration of tumor metastasis, and the removal of systemic hydrogen peroxide by PEG-catalase can inhibit the progression of diabetic conditions and tumor metastasis in diabetes.

    Inositol pyrophosphates are messenger molecules incorporating the energetic pyrophosphate bond. Although they have been implicated in diverse biologic processes, their physiologic functions remain enigmatic. We show that the catalytic activity of inositol hexakisphosphate kinase 2 (IP6K2), one of the principal enzymes generating the inositol pyrophosphate IP7 (5-diphosphoinositolpentakisphosphate), mediates cancer cell migration and tumor metastasis both in cell culture and intact mice.

    In carrying out bone scintigraphy in 224 cases over the 5 years from June, 1978 to May, 1983 as a part of the post-treatment management of cervical carcinoma. Bone metastases were seen in 12.5% (28 cases) of the subjects, about 6% of the total post-treatment cases of cervical carcinoma in the corresponding period (466 cases). Bone metastases were seen in 9.3% (16/172) of post-operative cases, compared with 23.1% (12/52) of non-operative cases. Bone metastases were not seen in clinical stages Ia through IIa (49 cases) but were seen in IIb or higher stages. Bone metastasis rates by histological type, according to WHO classification, were 12.8% (26/203) in squamous cell carcinoma, 5.9% (1/17) in adenocarcinoma, and 25% (1/4) in adenosquamous carcinoma. Among the squamous cell carcinoma cases, small cell non-keratinizing type had the highest bone metastasis rate (p<0.05). Of 172 post-operative cases, 20.8% (11/53) of those with lymphnode metastasis exhibited bone metastasis, higher than the 4.2% (5/119) in cases without lymphnode metastasis. As to CPL classification, bone metastasis was seen more often in L type (18.8%) than C(0.0%) or P types (6.6%). Our risk classification of 168 cases demonstrated that bone metastasis was not seen in risk I group (74 cases), but was seen in 6.7% (1/17) of risk II group and in 19.0% (15/79) of risk III group. Twenty-eight cases with bone metastasis included 11 cases with local recurrence, 8 with pulmonary metastases, 4 with hepatic metastases and 4 with Virchow's lymphnode metastases. The 28 bone metastasis cases included 10 cases with multiple bone metastases and 5 with only a single bone metastasis. Most bone metastases were seen in the lumbar vertebrae and the pelvic bone. Post-operative cases had more distant metastases than non-operative cases. On diagnosis of bone metastases and 17 of the 28 patients had pain, 6 of the remaining 11 patients developing pain thereafter. (J.P.N.)

    Zoledronic acid (Zol) is used to treat bone disease in both multiple myeloma (MM) and breast cancer patients with bone metastasis (BC). However, bones of MM and BC patients show a difference in retention of the bisphosphonate used for bone scintigraphy. Therefore, we hypothesized that disease...... of Zol correlated with bone-specific alkaline phosphatase (bALP) levels in BC (p = 0.001), and with CTX/bALP in Zol naive MM patients (p = 0.012). Especially in BC patients, WBrt correlated with age (p = 0.014) independently of kidney function. In MM patients WBrt was found to primarily correlate...... with the extent of bone disease (p = 0.028). Multivariate linear regression analyses of the entire cohort pointed out that WBrt of Zol was best predicted by age (p ...

    Patients with brain metastasis from melanoma have poor outcomes. Radiation is used both for prognostic and symptomatic value. We aimed to further clarify the role of stereotactic radiosurgery (SRS) and whole brain radiotherapy (WBRT) as well as the prognostic implication of various sites of extracranial disease. The records of 73 consecutive patients treated at the University of Rochester Medical Center for brain-metastatic melanoma from January 2004 to October 2013 were reviewed. The median overall survival (OS) was 3.0 months. Patients treated with WBRT alone had decreased OS compared to those treated with SRS alone (HR = 0.38, p = 0.001) or WBRT and SRS (HR = 0.51, p = 0.039). The mean number of brain metastasis differed (p = 0.002) in patients in patients who received WBRT (4.0) compared to those who did not (2.0). Among patients with extracranial disease (n = 63), bone metastasis (HR = 1.86, p = 0.047, n = 15) was a negative prognostic factor; liver (HR = 1.59, p = 0.113, n = 17), lung (HR = 1.51, p = 0.23, n = 51) and adrenal metastasis (HR = 1.70, p = 0.15, n = 10) were not. In patients with concurrent brain and lung metastasis, those with disease limited to those two sites (OS = 8.7 mo, n = 13) had improved OS (HR = 0.44, p = 0.014) compared to those with additional disease (OS = 1.8 mo, n = 50). Based on this hypothesis-generating retrospective analysis, SRS may offer survival benefit compared to WBRT alone in patients with brain metastatic melanoma. Bone metastasis appears to confer a particularly poor prognosis. Those with disease confined to the lung and brain may represent a population with improved prognosis.

    To compare drainage alone or combined with anti-tumor therapy for treatment of obstructive jaundice caused by recurrence and metastasis after primary tumor resection. We collect 42 patients with obstructive jaundice caused by recurrence and metastasis after tumor resection from January 2008 - August 2012, for which percutaneous transhepatic catheter drainage (pTCD)/ percutaneous transhepatic biliary stenting (pTBS) were performed. In 25 patients drainage was combined with anti-tumor treatment, antineoplastic therapy including intra/postprodure local treatment and postoperative systemic chemotherapy, the other 17 undergoing drainage only. We assessed the two kinds of treatment with regard to patient prognosis. Both treatments demonstrated good effects in reducing bilirubin levels in the short term and promoting liver function. The time to reobstruction was 125 days in the combined group and 89 days in the drainage only group; the mean survival times were 185 and 128 days, the differences being significant. Interventional drainage in the treatment of the obstructive jaundice caused by recurrence and metastasis after tumor resection can decrease bilirubin level quickly in a short term and promote the liver function recovery. Combined treatment prolongs the survival time and period before reobstruction as compared to drainage only.

    Full Text Available Background. Sweat gland carcinoma is a rare malignancy with a high metastatic potential seen more commonly in elderly patients. The scalp is the most common site of occurrence and it usually spreads to regional lymph nodes. Liver, lungs, and bones are the most common sites of distant metastasis. Late lung metastasis of sweat gland adenocarcinoma after a time span of 5 years is extremely rare. Aim. We report a patient with late lung metastasis of a primary sweat gland carcinoma 10 years after initial surgical resection. Conclusion. Sweat gland carcinomas are rare cancers with a poor prognosis. Surgery in the form of wide local excision and lymph node dissection is the mainstay of treatment. Late pulmonary metastases with a latency of 10 years have never been reported in the literature. This is the first clinical documentation of late lung metastasis from sweat gland carcinoma with a latency period of 10 years.

    Objective: To study the accuracy of liver volume measurement using MSCT and its application in liver transplantation. Methods: (1) Experimental study. Ten pig livers were scanned using MSCT with two collimations (3.2 mm and 6.5 mm) and pitch 1.25. Semi-automatic method was used to reconstruct 3D liver models to measure the liver volume. (2) Clinical study. Twenty-three patients received MSCT scan with collimation of 6.5 mm before liver transplantation. Same method was used to calculate the liver volume and the measurement was repeated by the same observer after 1 month. Results: (1) Experimental study. Actual liver volumes were (1134.1 ± 288.0) ml. Liver volumes by MSCT with two collimations were (1125.0 ± 282.5) ml (3.2 mm) and (1101.6 ± 277.6) ml (6.5 mm). The accuracy was (99.5 ± 0.8)% and (97.4 ± 0.8)%, respectively. Both showed same good agreement with actual liver volume: r=0.999, P<0.01 (2) Clinical study. Actual liver volumes were (1455.7±730.0) ml. Liver volume by MSCT was (1462.7 ± 774.1) ml. The accuracy was (99.5±9.6)%, r=0.986, P<0.01. Liver volume measured again was (1449.4 ± 768.9) ml, r=0.991 (P<0.01). Conclusion: MSCT can assess the liver volume correctly, and could be used as a routine step for evaluations before liver transplantation

    We aimed to assess the sensitivity of diffusion-weighted (DW) magnetic resonance (MR) imaging for the detection of pathologically confirmed uveal melanoma liver metastases (UMLM). Twenty patients who underwent complete surgical resection of their UMLM (N = 83) were included. Pre-surgery liver MR imaging included T2-weighted, T1-weighted, DW and dynamic-gadolinium-enhanced MR sequences. Two radiologists independently reviewed three sets of images (DW / morphologic-dynamic / combined) for each patient using intraoperative and pathological findings as a standard of reference. The sensitivities of the morphologic-dynamic and DW images for UMLM detection were 63 % and 59 %, respectively, for reader 1 (R1) and 64 % and 53 %, for reader 2 (R2). Sensitivity of the combined set was higher than sensitivity in the two other sets (R1:69 %, R2:67 %), but was only significantly different than the sensitivity of the DW images (McNemar test). For the three sets and the two readers, the sensitivity for UMLM smaller than 5 mm (37-46 %) was significantly lower than that for UMLM larger than 5 mm (67-90 %). The sensitivity for UMLM located in the subcapsular area (41-54 %) was significantly lower than that for intraparenchymal UMLM (68-86 %) (Chi-square test). Our study shows that the addition of DW imaging to morphologic-dynamic images does not significantly increase MR sensitivities for UMLM detection. (orig.)

    Few studies have investigated whether the Glasgow Prognostic Score (GPS), an inflammation-based prognostic score measured before resection of colorectal liver metastasis (CRLM), can predict postoperative survival. Sixty-three consecutive patients who underwent curative resection for CRLM were investigated. GPS was calculated on the basis of admission data as follows: patients with both an elevated C-reactive protein (>10 mg/l) and hypoalbuminemia (l) were allocated a GPS score of 2. Patients in whom only one of these biochemical abnormalities was present were allocated a GPS score of 1, and patients with a normal C-reactive protein and albumin were allocated a score of 0. Significant factors concerning survival were the number of liver metastases (p = 0.0044), carcinoembryonic antigen level (p = 0.0191), GPS (p = 0.0029), grade of liver metastasis (p = 0.0033), and the number of lymph node metastases around the primary cancer (p = 0.0087). Multivariate analysis showed the two independent prognostic variables: liver metastases > or =3 (relative risk 2.83) and GPS1/2 (relative risk 3.07). GPS measured before operation and the number of liver metastases may be used as novel predictors of postoperative outcomes in patients who underwent curative resection for CRLM. Copyright 2010 S.

    2017-10-01

    Full Text Available Pulmonary squamous cell carcinoma is the second most common non–small cell malignancy of the lung. It commonly metastasizes to the adrenal glands, bone, liver, brain, and kidneys. Most occurrences of metastatic squamous cell carcinoma involving the gastrointestinal tract originate from primary lung tumors. Metastasis to the duodenum, however, is exceedingly rare, with very few cases of stomach or duodenal involvement described in the literature. We report the case of a patient with stage IV pulmonary squamous cell carcinoma metastasizing to the duodenum with an uncommon presentation to add to the paucity of literature available regarding this rare finding.

    The aim of this study was to retrospectively compare the treatment efficacy of systemic chemotherapy combined with sequential CT-guided radiofrequency ablation (Chemo-RFA) to chemotherapy alone (Chemo-only) in the management of nasopharyngeal carcinoma (NPC) with liver metastasis. Between 2003 and 2011, 328 NPC patients diagnosed with liver metastasis at Sun Yat-sen University Cancer Center were enrolled. One-to-one matched pairs between Chemo-RFA group with the Chemo-only group were generated using propensity score matching. The associations of treatment modality with overall survival (OS) and progression-free survival (PFS) were determined by Cox regression. Of the patients enrolled, 37 patients (11.8 %) received combined treatment, 291 (82.2) received chemotherapy alone. The patients in Chemo-RFA group were more frequently classified as lower number (≤3) of liver metastatic lesions (Poligometastasis in liver, and should be considered if the ablation is technically feasible.

    Metastasis fingers (acral metastasis) are finding a poor prognosis. Past medical history should be questioned and metastasis from primary tumor should be kept in mind in patients with pain, swelling, and hyperemia in fingers. Successful surgical treatment on acral metastasis does not extend the life expectancy; however, it reduces the patient's pain during his terminal period, saves the functions of the limb, and increases life comfort.

    1984-01-01

    This study was performed to establish normal hepatoscintiangiographic (HSA) pattern of hepatic blood flow and to investigate differential HSA findings of primary and metastatic carcinomas and abscess of the liver. HSA was carried out after intravenous bolus injection of l0 mCi of Tc-99m-phytate by obtaining sequential anterior images of 1-second exposure for 16 seconds. Observations included (1) baseline study of normal hepatic blood flow patterns by correlating with contrast angiogram, (2) time-sequence phasing of normal HSA, and (3) analysis of altered patterns in primary and metastatic carcinomas and abscess of the liver. Results were: (1) Normal HSA demonstrated 3 distinct phases of arterialization (AP), arterial hepatrogram (AHP), and portal venous hepatogram (PVHP). The means of each phase were 5.3, 6.3, and 8.3 seconds, respectively. Portal vein could be seen in all but one of 20 normal subjects. (2) Pattern changes in disease groups were early start of AP in carcinomas and very early start of AP in abscess. AP became prolonged in all disease groups. (3) Distinction between AHP and PVHP was sharp in metastasis and abscess but was unsharp in primary hepatoma. Cold area or areas became vascularized in primary hepatoma but not in abscess. Cold areas of metastasis were inhomogenously vascularized in late AP and throughout AHP and became relatively avascular as PVHP began. The cold area of abscess showed rim enhancement during AH and APH. These differences in HSA pattern were very useful in differential diagnosis of the diseases studied

    Inguinal lymph node metastasis from adenocarcinoma arising at a colostomy site is extremely rare, and the significance of surgical resection for metastatic inguinal lymph nodes has not been established. An 82-year-old woman who had undergone abdominoperineal resection 27 years earlier was admitted to our hospital complaining of bleeding from a colostomy. Physical examination revealed that a tumor at the colostomy site directly invaded into the peristomal skin, and that a left inguinal lymph node was firm and swollen. Positron emission tomography/computed tomography scan demonstrated accumulation of (18)F-fluorodeoxy glucose into both the colostomy tumor and the left swollen inguinal lymph node, while there was no evidence of metastasis to liver or lungs. She underwent open left hemicolectomy with wide local resection of the colostomy, and dissection of left inguinal lymph nodes. Histological diagnosis was a moderately differentiated adenocarcinoma that directly invaded into the surrounding skin and metastasized to the left inguinal lymph node. The patient has been followed up for >5 years without any sign of recurrence. In general, inguinal lymph node metastasis from colorectal cancers is regarded as a systemic disease with a poor prognosis, and so systemic chemotherapy and radiotherapy, but not surgical lymph node dissection, are recommended. Considering the lymphatic drainage route in the present case, inguinal lymph node metastasis does not represent a systemic disease but rather a sentinel nodal metastasis from adenocarcinoma at a colostomy site. Surgical dissection of metastatic inguinal lymph nodes should be considered to enable a favorable prognosis in the absence of distant metastasis to other organs. © The Author 2014.

    2014-10-01

    Full Text Available We report a case of an 8-year-old girl with metastasis of malignant melanoma (MM to the ovary. She was initially diagnosed with cutaneous MM on the left buttock for which she underwent wide local excision, left inguinal/pelvic lymph node dissection, and subcutaneous injection of interferon beta. In spite of the treatment, she developed dissemination of MM to the liver, the bone, and the right ovary. All the lesions responded well to systemic chemotherapy (intravenous dacarbazine, except for the right ovarian tumor. She underwent an elective right salpingo-oophorectomy to avoid torsion or rupture of the tumor. However, she developed metastases to the contralateral ovary with peritoneal dissemination in 4 months. She received home palliative care and died at home 14 months after the last surgery. Ovarian metastasis of MM is a rare form of dissemination, and only 15 adult cases have ever been reported. Our patient is the first pediatric case. Since there is no standard of surgical indication for metastatic MM to the ovary, palliative resection can be an option for improving quality of life of a patient with this rare condition.

    2000-01-01

    The present is an overview of recent data that describes the genetic underpinnings of the suppression of cancer metastasis. Despite the explosion of new information about the genetics of cancer, only six human genes have thus far been shown to suppress metastasis functionally. Not all have been shown to be functional in breast carcinoma. Several additional genes inhibit various steps of the metastatic cascade, but do not necessarily block metastasis when tested using in vivo assays. The implications of this are discussed. Two recently discovered metastasis suppressor genes block proliferation of tumor cells at a secondary site, offering a new target for therapeutic intervention

    1997-01-01

    Positron Emission Computed Tomography (PET), is a nuclear medical diagnostic method by which tomographic images can be obtained non-invasively at a real time. The positron nuclides; 11 C, 13 N, 15 O or 18 F have comparatively high radioactivities which enable to make functional analysis of very small amounts of the cerebral receptors and cellular metabolism. In addition, PET can be used for the determination of blood flow level and thus, it became possible to study the area involved in learning and memory. Several positron-emitting compounds of low molecular weight have been utilized for medical studies and applications. The early courses of metastasis were investigated using (2- 18 F)2-fluoro-2-deoxyglucose ((2- 18 F)FDG). Metastatic cancerous cells labelled with (2- 18 F)FDG were injected into rodents and the radioactivities were monitored by PET, from an aspect of cell adhesion. B16BL6 and MTLn3 cells accumulated highly in the lung of rats in an early stage and gradually disappeared from the organ, whereas RAW 117 cells specifically accumulated in the liver through the early accumulation in the lung. These results indicate that the degree of early accumulation of malignant cells well reflects the feasibility of metastasis. (M.N.)

    2016-04-01

    Full Text Available Currently, sorafenib is the multi-target inhibitor for the treatment of advanced primary liver cancer, and can effectively prolong the progression-free survival and overall survival in patients with advanced primary liver cancer. The application of sorafenib in the targeted therapy for liver cancer has become a hot topic. Major targets or signaling pathways include Raf/Mek/Erk, Jak/Stat, PI3K/Akt/mTOR, VEGFR and PDGFR, STAT, microRNA, Wnt/β-catenin, autolysosome, and tumor-related proteins, and sorafenib can regulate the proliferation, differentiation, metastasis, and apoptosis of liver cancer cells through these targets. This article reviews the current research on the action of sorafenib on these targets or signaling pathways to provide useful references for further clinical research on sorafenib.

    2011-01-01

    Background. Stereotactic body radiotherapy (SBRT) is often the preferred treatment for the advanced liver tumours which owing to tumour distribution, size and multi-focality are out of range of surgical resection or radiofrequency ablation. However, only a minority of patients with liver tumours may be candidates for conventional SBRT because of the limited radiation tolerance of normal liver, intestine and other normal tissues. Due to the favourable depth-dose characteristics of protons, intensity-modulated proton therapy (IMPT) may be a superior alternative to photon-based SBRT. The purpose of this treatment planning study was therefore to investigate the potential sparing of normal liver by IMPT compared to photon-based intensity-modulated radiotherapy (IMRT) for solitary liver tumours. Material and methods. Ten patients with solitary liver metastasis treated at our institution with multi-field SBRT were retrospectively re-planned with IMRT and proton pencil beam scanning techniques. For the proton plans, two to three coplanar fields were used in contrast to five to six coplanar and non-coplanar photon fields. The same planning objectives were used for both techniques. A risk adapted dose prescription to the PTV surface of 12.5-16.75 Gy x 3 was used. Results. The spared liver volume for IMPT was higher compared to IMRT in all 10 patients. At the highest prescription dose level, the median liver volume receiving less than 15 Gy was 1411 cm 3 for IMPT and 955 cm 3 for IMRT (p D 15 Gy > 700 cm 3 constraint. For the D mean = 15 Gy constraint, nine of 10 cases could be treated at the highest dose level using IMPT whereas with IMRT, only two cases met this constraint at the highest dose level and six at the lowest dose level. Conclusion. A considerable sparing of normal liver tissue can be obtained using proton-based SBRT for solitary liver tumours

    2016-06-01

    Full Text Available Carcinoma of the ampulla of Vater is a rare gastrointestinal tumor. Additionally, cutaneous metastasis from such an internal malignancy is also uncommon. We reported the case of a 55-year-old man afflicted with ampullary carcinoma with cutaneous metastasis. The patient did not undergo the standard Whipple procedure but received chemotherapy due to apparent left neck lymph node metastasis noted by initial PET/CT imaging. The skin metastasis presented as a left neck infiltrating purpuric lesion, which was confirmed by skin biopsy approximately one year after the patient's disease was first diagnosed. Thereafter, the patient received further chemotherapy pursuant to his course of medical management. Skin metastasis usually represents a poor patient prognosis. In these cases, treatment of cutaneous metastasis typically includes systemic chemotherapy and local management such as radiation therapy or tumor excision. And when choosing a chemotherapy regimen for the ampullary cancer, the histological subtypes (intestinal or pancreatobiliary should be comprehensively considered. In our review of the literature, the intestinal type seems to have less distant lymph node metastasis, advanced local invasion, as well as recurrence than pancreatobiliary type of ampullary cancer.

    Full Text Available Objective: In this study, urinary pyridinoline (uPYR, urinary deoxypyridinoline (uDPD and serum alkaline phosphatase (sALP levels were measured in patients without metastatic breast cancer and the role of uPYR and uDPD as biochemical markers of bone metastases were examined during a six years follow-up.Materials and methods: Totally, 34 patients without bone metastasis and 40 healthy individuals as a control group were included in the study.Results: Urinary pyridinoline and uDPD levels were significantly higher in patients without bone metastasis than in normal controls (p<0,05, except sALP levels. As a result of a 6-year follow-up of patients, 20.5% had metastasis. The distribution of metastasis types was as follows: 2.9% of those patients had local, 2.9% had liver, 5.9% had lung and 8.8% had bone metastasis. The cut off value, sensitivity and specifity of uPYR was established as 47,3 pmol/μmol creatinin, 82% and 80% respectively. The cut off value, sensitivity and specifity of uDPD were determined as 9.53 pmol/μmol creatinin, 76%, 72% respectively.Conclusions: This study demonstrated that measurement of urinary collagen cross-links assay may contribute to the early detection of metastatic spread to bone in breast cancer. However further studies with larger scaled groups should be performed. J Clin Exp Invest 2011; 2 (4: 420-424

    FOXO4, a member of the FOXO family of transcription factors, is currently the focus of intense study. Its role and function in gastric cancer have not been fully elucidated. The present study was aimed to investigate the expression profile of FOXO4 in gastric cancer and the effect of FOXO4 on cancer cell growth and metastasis. Immunohistochemistry, Western blotting and qRT-PCR were performed to detect the FOXO4 expression in gastric cancer cells and tissues. Cell biological assays, subcutaneous tumorigenicity and tail vein metastatic assay in combination with lentivirus construction were performed to detect the impact of FOXO4 to gastric cancer in proliferation and metastasis in vitro and in vivo. Confocal and qRT-PCR were performed to explore the mechanisms. We found that the expression of FOXO4 was decreased significantly in most gastric cancer tissues and in various human gastric cancer cell lines. Up-regulating FOXO4 inhibited the growth and metastasis of gastric cancer cell lines in vitro and led to dramatic attenuation of tumor growth, and liver and lung metastasis in vivo, whereas down-regulating FOXO4 with specific siRNAs promoted the growth and metastasis of gastric cancer cell lines. Furthermore, we found that up-regulating FOXO4 could induce significant G1 arrest and S phase reduction and down-regulation of the expression of vimentin. Our data suggest that loss of FOXO4 expression contributes to gastric cancer growth and metastasis, and it may serve as a potential therapeutic target for gastric cancer

    To evaluate the feasibility of mesorectal vascular invasion (MVI) in predicting early distant metastasis developed within 1 year of diagnosis of T3 rectal cancer using magnetic resonance imaging (MRI) Sixty-five patients with T3 rectal cancer (early metastasis, n = 28; non-metastasis, n = 37) were enrolled in this study. Early distant metastases developed in 28 patients (liver, n = 15; lung, n = 9; both, n = 4). Logistic regression was used to determine the independent predictors for early distant metastasis. In univariate analysis, tumour location, carcinoembryonic antigen (CEA), lymphovascular invasion (LVI), MRI-detected MVI, and mesorectal fat infiltration (MFI) (odds ratio [OR], 4.533, 9.583, 5.539, 27.046, and 5.539, respectively) were associated with early distant metastasis. Multivariate analysis demonstrated that MVI (OR, 29.949; P < 0.002) and LVI (OR, 6.684; P = 0.033) were independent factors for early distant metastasis. Specificity and positive predictive value (PPV) of MVI (94.59 %, and 89.47 %, respectively) were significantly higher than those of LVI (64.86 %, and 61.76 %), but sensitivity and negative predictive value were not significantly different between MVI (60.71 %, and 76.09 %) and LVI (75.00 %, and 77.42 %). While sensitivity of MRI-detected MVI was equal to that of CEA in predicting early distant metastasis from T3 rectal cancer, specificity and PPV may be improved by assessing MVI. (orig.)

    To determine if identifiable hepatic textural features are present at abdominal CT in patients with colorectal cancer (CRC) prior to the development of CT-detectable hepatic metastases. Four filtration-histogram texture features (standard deviation, skewness, entropy and kurtosis) were extracted from the liver parenchyma on portal venous phase CT images at staging and post-treatment surveillance. Surveillance scans corresponded to the last scan prior to the development of CT-detectable CRC liver metastases in 29 patients (median time interval, 6 months), and these were compared with interval-matched surveillance scans in 60 CRC patients who did not develop liver metastases. Predictive models of liver metastasis-free survival and overall survival were built using regularised Cox proportional hazards regression. Texture features did not significantly differ between cases and controls. For Cox models using all features as predictors, all coefficients were shrunk to zero, suggesting no association between any CT texture features and outcomes. Prognostic indices derived from entropy features at surveillance CT incorrectly classified patients into risk groups for future liver metastases (p < 0.001). On surveillance CT scans immediately prior to the development of CRC liver metastases, we found no evidence suggesting that changes in identifiable hepatic texture features were predictive of their development. • No correlation between liver texture features and metastasis-free survival was observed. • Liver texture features incorrectly classified patients into risk groups for liver metastases. • Standardised texture analysis workflows need to be developed to improve research reproducibility.

    Full Text Available Abstract Background Distant metastases from colon cancer spread most frequently to the liver and the lung. Risk factors include positive lymph nodes and high grade tumors. Isolated metastases to the appendicular skeleton are very rare, particularly in the absence of identifiable risk factors. Case report The patient was a 55 year old male with no previous personal or family history of colon cancer. Routine screening revealed a sigmoid adenocarcinoma. He underwent resection with primary anastomosis and was found to have Stage IIA colon cancer. He declined chemotherapy as part of a clinical trial, and eight months later was found to have an isolated metastasis in his right scapula. This was treated medically, but grew to 12 × 15 cm. The patient underwent a curative forequarter amputation and is now more than four years from his original colon surgery. Discussion Stage IIA colon cancers are associated with a high five year survival rate, and chemotherapy is not automatically given. If metastases occur, they are likely to arise from local recurrence or follow lymphatic dissemination to the liver or lungs. Isolated skeletal metastases are quite rare and are usually confined to the axial skeleton. To our knowledge, this is the first reported case of an isolated scapular metastasis in a patient with node negative disease. The decision to treat the recurrence with radiation and chemotherapy did not reduce the tumor, and a forequarter amputation was eventually required. Conclusion This case highlights the importance of adequately analyzing the stage of colon cancer and offering appropriate treatment. Equally important is the early involvement of a surgeon in discussing the timing of the treatment for recurrence. Perhaps if the patient had received chemotherapy or earlier resection, he could have been spared the forequarter amputation. The physician must also be aware of the remote possibility of an unusual presentation of metastasis in order to pursue

    CD147 is a transmembrane protein that can induce the expression and activity of matrix metalloproteinases (MMPs). Expression of CD147 has been shown to potentiate cell migration, invasion, and metastasis of cancer. In this study, the critical role of CD147 in metastasis was elucidated using CD147-overexpressing cholangiocarcinoma (CCA) cells in vitro and in vivo. The molecular mechanism, demonstrated herein, supported the hypothesis that metastasis increased in CD147-overexpressing cells. Five CD147-overexpressing clones (Ex-CD147) were established from a low CD147-expressing CCA cell line, KKU-055, using lentivirus containing pReceiver-Lenti-CD147. The metastatic capability was determined using the tail vein injection mouse model and an in vitro 3D invasion assay. Liver colonization was assessed using anti-HLA class I immunohistochemistry. Adhesion abilities, cytoskeletal arrangements, MMP activities, the expressions of adhesion molecules, and epithelial-mesenchymal transitional markers were analyzed. All Ex-CD147 clones exhibited a high CD147 expression and high liver colonization in the tail vein-injected mouse model, whereas parental cells lacked this ability. Ex-CD147 clones exhibited metastatic phenotypes (i.e., an increase in F-actin rearrangement) and cell invasion and a decrease in cell adhesion. The molecular mechanisms were shown to be via the induction of MMP-2 activity and enhancement of epithelial-mesenchymal transitions. An increase in mesenchymal markers Slug, vimentin, and N-cadherin, and a decrease in epithelial markers E-cadherin and claudin-1, together with suppression of the adhesion molecule ICAM-1, were observed in the Ex-CD147 clones. Moreover, suppression of CD147 expression using siCD147 in two CCA cell lines with high CD147 expression significantly decreased cell migration and invasion of these CCA cells. These findings emphasize the essential role of CD147 in CCA metastasis and suggest CD147 as a promising target for the effective

    The purpose of this study is to introduce a novel approach to incorporate patient-specific breathing variability information into 4D dose simulation of volumetric arc therapy (VMAT)-based stereotactic body radiotherapy (SBRT) of extracranial metastases. Feasibility of the approach is illustrated by application to treatment planning and motion data of lung and liver metastasis patients. The novel 4D dose simulation approach makes use of a regression-based correspondence model that allows representing patient motion variability by breathing signal-steered interpolation and extrapolation of deformable image registration motion fields. To predict the internal patient motion during treatment with only external breathing signal measurements being available, the patients’ internal motion information and external breathing signals acquired during 4D CT imaging were correlated. Combining the correspondence model, patient-specific breathing signal measurements during treatment and time-resolved information about dose delivery, reconstruction of a motion variability-affected dose becomes possible. As a proof of concept, the proposed approach is illustrated by a retrospective 4D simulation of VMAT-based SBRT treatment of ten patients with 15 treated lung and liver metastases and known clinical endpoints for the individual metastases (local metastasis recurrence yes/no). Resulting 4D-simulated dose distributions were compared to motion-affected dose distributions estimated by standard 4D CT-only dose accumulation and the originally (i.e. statically) planned dose distributions by means of GTV D98 indices (dose to 98% of the GTV volume). A potential linkage of metastasis-specific endpoints to differences between GTV D98 indices of planned and 4D-simulated dose distributions was analyzed.

    Full Text Available Abstract Colorectal cancer (CRC is the third most common cancer in the word. Liver metastasis is the most common site of colorectal metastases. The prognosis of resectable colorectal liver metastases (CRLM was improved in the recent years with the consideration of chemotherapy and surgical resection as part of the multidisciplinary management of the disease; the current 5-year survival rates after resection of liver metastases are 25% to 40%. Resectable synchronous or metachronous liver metastases should be treated with perioperative chemotherapy based on three months of FOLFOX4 (5-fluorouracil [5FU], folinic acid [LV], and oxaliplatin chemotherapy before surgery and three months after surgery. In the case of primary surgery, pseudo-adjuvant chemotherapy for 6 months, based on 5FU/LV, FOLFOX4, XELOX (capecitabine and oxaliplatin or FOLFIRI (5FU/LV and irinotecan, should be indicated. In potentially resectable disease, primary chemotherapy based on more intensive regimens such as FOLFIRINOX (5FU/LV, irinotecan and oxaliplatin should be considered to enhance the chance of cure. The palliative chemotherapy based on FOLFIRI, or FOLFOX4/XELOX with or without targeted therapies, is the mainstay treatment of unresectable disease. This review would provide additional insight into the problem of optimal integration of chemotherapy and surgery in the management of CRLM.

    Intra-arterial infusion liver scintigraphy was performed in 11 patients with primary or metastatic liver tumor. and intraportal infusion liver scintigraphy was performed in 6 patients for prophylaxis of liver metastasis from colorectal cancer. 99m Tc-Sn colloid or 99m Tc-phytate was administered through the catheter of which tip was placed in the portal vein or the hepatic artery, and then liver image was obtained. When 99m Tc-phytate was infused intra-arterially, significant amount of the infused tracer passed through the liver and we could not get sufficient information to assess the distribution of drug administered through the catheter. On the other hand, intraportal infusion liver scintigraphy using 99m Tc-Sn colloid or 99m Tc-phytate and intra-arterial infusion liver scintigraphy using 99m Tc-Sn colloid revealed heterogenity of liver uptake, tracer uptake in spleen, low uptake area corresponding to the liver tumor and high uptake area around it. The findings will be clinically useful, and these methods are thought to be helpful to confirm the satisfactory drug distribution. (author)

  9. Anti-metastasis effect of fucoidan from Undaria pinnatifida sporophylls in mouse hepatocarcinoma Hca-F cells.

    Peisheng Wang

    Full Text Available Metastasis is one of the major causes of cancer-related death. It is a complex biological process involving multiple genes, steps, and phases. It is also closely connected to many biological activities of cancer cells, such as growth, invasion, adhesion, hematogenous metastasis, and lymphatic metastasis. Fucoidan derived from Undaria pinnatifida sporophylls (Ups-fucoidan is a sulfated polysaccharide with more biological activities than other fucoidans. However, there is no information on the effects of Ups-fucoidan on tumor invasion and metastasis. We used the mouse hepatocarcinoma Hca-F cell line, which has high invasive and lymphatic metastasis potential in vitro and in vivo, to examine the effect of Ups-fucoidan on cancer cell invasion and metastasis. Ups-fucoidan exerted a concentration- and time-dependent inhibitory effect on tumor metastasis in vivo and inhibited Hca-F cell growth, migration, invasion, and adhesion capabilities in vitro. Ups-fucoidan inhibited growth and metastasis by downregulating vascular endothelial growth factor (VEGF C/VEGF receptor 3, hepatocyte growth factor/c-MET, cyclin D1, cyclin-dependent kinase 4, phosphorylated (p phosphoinositide 3-kinase, p-Akt, p-extracellular signal regulated kinase (ERK 1/2, and nuclear transcription factor-κB (NF-κB, and suppressed adhesion and invasion by downregulating L-Selectin, and upregulating protein levels of tissue inhibitor of metalloproteinases (TIMPs. The results suggest that Ups-fucoidan suppresses Hca-F cell growth, adhesion, invasion, and metastasis capabilities and that these functions are mediated through the mechanism involving inactivation of the NF-κB pathway mediated by PI3K/Akt and ERK signaling pathways.

    Fine-needle aspiration (FNA) with cytological evaluation reliably diagnoses primary and secondary thyroid neoplasms. However, identifying the primary origin of a metastatic process involving the thyroid gland is challenging. In particular, metastasis of colon cancer to the thyroid gland is very rare. In this case report, a right lobe solid thyroid nodule in a 66-year-old male was aspirated. FNA cytology showed necrosis and atypical tall columnar cells; since, the patient at age 60 had undergone surgery for a sigmoid-rectal cancer metastasizing to the liver and subsequently to the lung, a suspicion of metastasis from colon cancer was raised. This was corroborated by cell-block immunocytochemistry showing a cytokeratin (CK) 7 negative/CK20-positive staining pattern; thyreoglobulin and TTF-1 were both negative. Since KRAS codon 12/13 mutations frequently occur in colon cancer, whereas they are extremely uncommon in primary thyroid tumors, DNA was extracted from the aspirated cells, and KRAS mutational analysis was carried out. The codon 12 G12D mutation was found; the same mutation was evident in the primary cancer of the colon and in its liver and lung metastasis. Thus, a combined cytological, immunocytochemical and molecular approach unquestionably correlated metastatic adenocarcinoma cells aspirated from the thyroid to a colo-rectal origin. © 2010 Wiley-Liss, Inc.

    The difference between liver hemangioma and metastases is a subject of clinical interest. Nineteen MR liver studies are presented, 10 of them correspond to hemangiomas and 9 to metastases. In all cases, intravenous gadolinium was used in dynamic slices with T1-weighted gradient echo sequences. Late uptake is studied in two lesions. One minute postinjection, the periphery appears hyperintense (more so than the fatty tissue) in 7 out of the 10 cases of hemangioma; in 4 cases, the metastases show less intense uptake than fatty tissue. From two and a half minutes on, the periphery is hyperintense (more so than the fatty tissue) in all the hemangiomas, while in 4 metastases, the periphery is hyperintense (but less so than the fatty tissue), and the rest of the metastases remain hypo-isointense. Uptake by the hemangiomas at two hours reveals the isointense lesion with the liver. In conclusion, at approximately one minute postinjection, hemangiomas show very marked and nodular uptake, with centripetal progression; the hypersignal persists in late slices. However, the metastases present variable, moderate, irregular uptake at the beginning, with no central progression and reduced contrast in the late slices at 5 minutes. In some cases, Gd-DTPA increases the diagnostic certainty, improving reliability with respect to conventional MR. (Author)

    Apigenin is a natural flavonoid which possesses multiple anti-cancer properties such as anti-proliferation, anti-inflammation, and anti-metastasis in many types of cancers including colorectal cancer. Neural precursor cell expressed developmentally downregulated 9 (NEDD9) is a multi-domain scaffolding protein of the Cas family which has been shown to correlate with cancer metastasis and progression. The present study investigates the role of NEDD9 in apigenin-inhibited cell migration, invasion, and metastasis of colorectal adenocarcinoma DLD1 and SW480 cells. The results show that knockdown of NEDD9 inhibited cell migration, invasion, and metastasis and that overexpression of NEDD9 promoted cell migration and invasion of DLD1 cells and SW4890 cells. Apigenin treatment attenuated NEDD9 expression at protein level, resulting in reduced phosphorylations of FAK, Src, and Akt, leading to inhibition on cell migration, invasion, and metastasis of both DLD1 and SW480 cells. The present study has demonstrated that apigenin inhibits cell migration, invasion, and metastasis through NEDD9/Src/Akt cascade in colorectal cancer cells. NEDD9 may function as a biomarker for evaluation of cancer aggressiveness and for selection of therapeutic drugs against cancer progression. - Highlights: • Apigenin inhibits migration, invasion, and metastasis of colorectal cancer cells. • Apigenin downregulates NEDD9. • Apigenin decreases phosphorylations of FAK, Src, and Akt. • Apigenin inhibits cell migration, invasion, and metastasis through NEDD9/Src/Akt.

    The treatment of patients with colorectal liver metastasis has improved significantly and first line therapy is often combined chemotherapy and bevacizumab, although it is unknown who responds to this regimen. Colorectal liver metastases grow in different histological growth patterns showing differences in angiogenesis. To identify possible response markers, histological markers of angiogenesis were assessed. Patients who underwent resection of colorectal liver metastasis at Rigshospitalet, Copenhagen, Denmark from 2007 to 2011 were included (n = 254) including untreated and patients treated with chemotherapy or chemotherapy plus bevacizumab. The resected liver metastases were characterised with respect to growth pattern, endothelial and tumour cell proliferation as well as microvessel density and tumour regression. Tumour regression grade of liver metastases differed significantly between untreated/chemotherapy treated patients in comparison to chemotherapy plus bevacizumab treated patients (both p chemotherapy-treated patients (p = 0.006/p = 0.002). Tumour cell proliferation assessed by Ki67 expression correlated to a shorter recurrence free survival in the total patient cohort. In conclusion, liver metastases from patients treated with neo-adjuvant chemotherapy and bevacizumab had significantly lower microvessel densities and tumour regression grades when compared to liver metastases from untreated or chemotherapy treated patients. This may indicate that bevacizumab treatment results in altered vascular biology and tumour viability, with possible tumour reducing effect. © 2015 UICC.

    Full Text Available We here report a 60-year-old woman in whom autopsy revealed a metastasis in the right cardiac ventricle from a well-differentiated squamous cell carcinoma (SCC of the left hand. The tumors in the myocardium and left hand were both well-differentiated SCCs with keratinization and sporadic keratin pearls. High concentrations of heart failure markers together with a pericardial effusion suggested antemortem chronic heart failure. Our case is particularly unusual because there were no regional lymph node metastases and the cardiac metastasis was not one of multiple metastases; thus, hematogenous metastasis to the right side of the heart alone had occurred.

    There are scant data regarding oncologic outcomes of laparoscopic liver resection (LLR). The aim of this study is to analyze the oncologic outcomes of LLR for malignant liver tumors (MLT). This was a prospective IRB-approved study of 123 patients with MLT undergoing LLR. Kaplan-Meier disease-free (DFS) and overall survival (OS) was calculated. Tumor type was colorectal in 61%, hepatocellular cancer in 21%, neuroendocrine in 5% and others in 13%. Mean tumor size was 3.2 ± 1.9 cm and number of tumors 1.6 ± 1.2. A wedge resection or segmentectomy was performed in 63.4%, bisegmentectomy in 24.4%, and hemihepatectomy in 12.2%. Procedures were totally laparoscopic in 67% and hand-assisted in 33%. Operative time was 235.2 ± 94.3 min, and conversion rate 7.3%. An R0 resection was achieved in 90% of patients and 94% of tumors. Median hospital stay was 3 days. Morbidity was 22% and mortality 0.8%. For patients with colorectal liver metastasis, DFS and OS at 2 years was 47% and 88%, respectively. This study shows that LLR is a safe and efficacious treatment for selected patients with MLT. Complete resection and margin recurrence rate are comparable to open series in the literature. © 2015 Wiley Periodicals, Inc.

    Purpose: To compare the mangafodipir trisodium (MnDPDP)-enhanced and ferucarbotran-enhanced magnetic resonance imaging (MRI) for the detection of hepatic metastases. Material and methods: Twenty patients with known hepatic metastasis underwent MR imaging using mangafodipir trisodium and ferucarbotran in at least 1-day intervals. Thirty-eight metastases were confirmed either histologically or clinically. Two radiologists independently reviewed the MnDPDP-enhanced and ferucarbotran-enhanced sets in a random order. The sensitivity and accuracy of lesion detection and the ability to distinguish a benign lesion from a malignant lesion were compared by the areas (Az) under the receiver operating characteristic (ROC) curve. The lesion-liver contrast-to-noise ratios (CNR) were compared by paired t-test. Results: The overall accuracy for detecting metastases was not significantly different between the MnDPDP set (Az = 0.912 and 0.913 for reader 1 and 2, respectively) and the SPIO set (Az = 0.920 and 0.950). The CNR at the MnDPDP-enhanced images and the SPIO-enhanced images were not significantly different (P = 0.146). Conclusion: Both MnDPDP- and ferucarbotran-enhanced MRI have a comparable accuracy in detecting hepatic metastasis

    Liver transplantation is the most effective treatment for selected patients with hepatocellular carcinoma. However, cancer recurrence, posttransplantation, remains to be the critical issue that affects the long-term outcome of hepatocellular carcinoma recipients. In addition to tumor biology itself, increasing evidence demonstrates that acute-phase liver graft injury is a result of hepatic ischemia reperfusion injury (which is an inevitable consequence during liver transplantation) and may promote cancer recurrence at late phase posttransplantation. The liver grafts from living donors, donors after cardiac death, and steatotic donors have been considered as promising sources of organs for liver transplantation and are associated with high incidence of liver graft injury. The acute-phase liver graft injury will trigger a series of inflammatory cascades, which may not only activate the cell signaling pathways regulating the tumor cell invasion and migration but also mobilize the circulating progenitor and immune cells to facilitate tumor recurrence and metastasis. The injured liver graft may also provide the favorable microenvironment for tumor cell growth, migration, and invasion through the disturbance of microcirculatory barrier function, induction of hypoxia and angiogenesis. This review aims to summarize the latest findings about the role and mechanisms of liver graft injury resulted from hepatic ischemia reperfusion injury on tumor recurrence posttransplantation, both in clinical and animal cohorts.

    Every year, approximately 68,000 new cases of malignant melanoma are diagnosed in the US. Ethanol consumption inhibits metastasis of melanoma in mice, but the mechanism is not well understood. C57BL/6J ob/+ mice, given either water or 20% ethanol, were injected intravenously with B16-BL6 melanoma cells to determine pulmonary metastasis. The effects of ethanol on cell phenotypes and markers of the epithelial-to-mesenchymal transition were determined in cell culture. In mice, ethanol consumption inhibited experimental pulmonary metastasis. This inhibition was associated with decreased body weight, and levels of systemic leptin, and insulin. In cell culture, ethanol inhibited B16-BL6 cell motility, invasion, and anchorage-independent growth. Additionally, ethanol reduced Snai1 expression and increased E-cadherin expression. Lastly, ethanol increased the expression of Kiss1 metastasis-suppressor and the metastasis suppressor Nm23/nucleoside diphosphate kinase. In both animal and in cell culture conditions, ethanol inhibited the metastatic ability of B16-BL6 melanoma cells.

    Full Text Available Introduction. Operations are performed for broader liver surgery indications for a better understanding of hepatic anatomy/physiology and developments in operation technology. Surgery can cure some patients with liver metastasis of some tumors. Nevertheless, postoperative liver failure is the most feared complication causing mortality in patients who have undergone excision of a large liver mass. The human amniotic membrane has regenerative effects. Thus, we investigated the effects of the human amniotic membrane on regeneration of the resected liver. Methods. Twenty female Wistar albino rats were divided into control and experimental groups and underwent a 70% hepatectomy. The human amniotic membrane was placed over the residual liver in the experimental group. Relative liver weight, histopathological features, and biochemical parameters were assessed on postoperative day 3. Results. Total protein and albumin levels were significantly lower in the experimental group than in the control group. No difference in relative liver weight was observed between the groups. Hepatocyte mitotic count was significantly higher in the experimental group than in the control group. Hepatic steatosis was detected in the experimental group. Conclusion. Applying the amniotic membrane to residual liver adversely affected liver regeneration. However, mesenchymal stem cell research has the potential to accelerate liver regeneration investigations.

    We retrospectively reviewed a series of proven lung metastasis to evaluate the frequency and CT features of metastases showing an air-space (lepidic) pattern of growth. CT examinations of 65 patients with proven lung metastasis from GI carcinomas were reviewed by three observers. Four CT features were used to classify lesions as air-space metastases: (a) air-space nodules; (b) parenchymal consolidation containing air bronchogram and/or showing angiogram sign; (c) focal or extensive ground-glass opacities; and (d) nodule(s) with a {open_quotes}halo{close_quotes} sign. Six of 65 patients showed air-space metastases: three from pancreatic carcinoma. two from colonic carcinoma, and one from jejunal carcinoma. In one case, metastasis appeared as extensive parenchymal consolidation associated with ground-glass opacities; in one as an area of ground-glass opacity; in one as an extensive parenchymal consolidation with air bronchogram; in one as parenchymal consolidations with angiogram sign and multiple nodules, some of these with halo sign; in one as air-space nodules and patchy air-space consolidations; and in one as a solitary nodule with halo sign. Our study shows that air-space lung metastasis from GI carcinomas is uncommon but not rare. On CT as well as microscopically, differential diagnosis between air-space metastasis and bronchioloalveolar carcinoma may be impossible. 13 refs., 5 figs., 1 tab.

    The spleen in rarely the place for solid, non-haematological tumors, isolated splenic metastases from adenocarcinomas being extremely rare findings, regardless of the origin and the histological type of the primary tumor. We present the case of a female patient with isolated splenic metastasis diagnosed by abdominal computer tomography at only 20 months after curative surgery for endometrial adenocarcinoma, in which the final diagnosis has been established by histological and immunohistochemical examination of the splenectomy piece. The haematogenous dissemination of the endometrial cancer occurs most commonly in the lungs, liver or bones, the spleen being rarely affected. In the medical literature there are cited up to date only 12 cases of solitary splenic metastasis from endometrial adenocarcinoma. The particularity of the case presented by us is the early appearance of an isolated splenic metastasis, at less than two years after curative surgery (compared to an average of 4-5 years cited in the literature), from an endometrial cancer which was classified histologicaly in the group with low-risk for relapse (well differentiated endometrioid adenocarcinoma). In conclusion, although solitary splenic secondary determinations are very rare, the incidence of the reported cases in the medical literature is increasing, their late appearance (a few years after the primary tumor's resection) and the lack of symptoms until the tumor reaches appreciable size or it complicates with necrosis, justifies the periodic abdominal imaging examination, on long-term, for postoperative monitorisation after the initial curative surgery. Their treatment of choice is open, classical splenectomy that must be followed by chemotherapy in order to prevent the development of other possible micrometastases.

    Full Text Available Metastasis, the greatest clinical challenge associated with cancer, is closely connected to multiple biological processes, including invasion and adhesion. The hypoxic environment in tumors is an important factor that causes tumor metastasis by activating HIF-1α. Fucoidan, extracted from brown algae, is a sulfated polysaccharide and, as a novel marine biological material, has been used to treat various disorders in China, Korea, Japan and other countries. In the present study, we demonstrated that fucoidan derived from Undaria pinnatifida sporophylls significantly inhibits the hypoxia-induced expression, nuclear translocation and activity of HIF-1α, the synthesis and secretion of VEGF-C and HGF, cell invasion and lymphatic metastasis in a mouse hepatocarcinoma Hca-F cell line. Fucoidan also suppressed lymphangiogenesis in vitro and in vivo. In addition, accompanied by a reduction in the HIF-1α nuclear translocation and activity, fucoidan significantly reduced the levels of p-PI3K, p-Akt, p-mTOR, p-ERK, NF-κB, MMP-2 and MMP-9, but increased TIMP-1 levels. These results indicate strongly that the anti-metastasis and anti-lymphangiogenesis activities of fucoidan are mediated by suppressing HIF-1α/VEGF-C, which attenuates the PI3K/Akt/mTOR signaling pathways.

    Metastatic tumors of hypophyseal gland are infrequent. Most are silent lesions discovered accidentally in necropsy. Appearance of symptomatic metastasis is however, exceptional. We describe here clinical and radiological findings in a female patient aged 69, presenting with a non-differential carcinoma of lung, diagnosed two years a half ago, starting with headache and visual disorders without hypopituitarism and insipidus diabetes. We made a nuclear magnetic resonance and diagnosis was a hypophyseal lesion operated on by trans-esphenoidal route, and Pathological Anatomy Service reports a metastasis of lung carcinoma. (Author)

    Full Text Available Spinal epidural cavernomas are quite rare lesions and only 5% of all cavernomas are located in the spine. The lesions are most commonly localized in the thoracic region. The differential diagnosis includes neurogenic tumors, lymphoma, schwannoma, meningioma, multiple myeloma, Ewing's sarcoma and metastasis. A 40- year-old male patient presented with paraplegia and MR images revealed an epidural soft tissue constricting the right posterolateral of the cord at the T6 level. Pathology showed cavernous hemangioma. A literature search revealed no other case that so closely mimicked metastasis by invading all components of the thoracic vertebra and also expanding to the epidural distance. We therefore present the case emphasizing these features.

    The stepwise progression of common endoderm progenitors into differentiated liver and pancreas organs is regulated by a dynamic array of signals that are not well understood. The nuclear receptor subfamily 5, group A, member 2 gene nr5a2, also known as Liver receptor homolog-1 (Lrh-1) is expressed in several tissues including the developing liver and pancreas. Here, we interrogate the role of Nr5a2 at multiple developmental stages using genetic and chemical approaches and uncover novel pleiotropic requirements during zebrafish liver and pancreas development. Zygotic loss of nr5a2 in a targeted genetic null mutant disrupted the development of the exocrine pancreas and liver, while leaving the endocrine pancreas intact. Loss of nr5a2 abrogated exocrine pancreas markers such as trypsin, while pancreas progenitors marked by ptf1a or pdx1 remained unaffected, suggesting a role for Nr5a2 in regulating pancreatic acinar cell differentiation. In the developing liver, Nr5a2 regulates hepatic progenitor outgrowth and differentiation, as nr5a2 mutants exhibited reduced hepatoblast markers hnf4α and prox1 as well as differentiated hepatocyte marker fabp10a. Through the first in vivo use of Nr5a2 chemical antagonist Cpd3, the iterative requirement for Nr5a2 for exocrine pancreas and liver differentiation was temporally elucidated: chemical inhibition of Nr5a2 function during hepatopancreas progenitor specification was sufficient to disrupt exocrine pancreas formation and enhance the size of the embryonic liver, suggesting that Nr5a2 regulates hepatic versus pancreatic progenitor fate choice. Chemical inhibition of Nr5a2 at a later time during pancreas and liver differentiation was sufficient to block the formation of mature acinar cells and hepatocytes. These findings define critical iterative and pleiotropic roles for Nr5a2 at distinct stages of pancreas and liver organogenesis, and provide novel perspectives for interpreting the role of Nr5a2 in disease.

    Full Text Available Background and objective Cancer metastasis is not only the malignant marker and characteristics, but also the main cause of failure to cure and lose their life in the patients with lung cancer. Lung cancer metastasis has organ-specific characteristics. The most common sites of lung cancer metastasis are mediastinal lymph node, brain, bone, liver and adrenal gland. The aim of this study is to screen and establish lung cancer cell model with organ-specific metastasis potential with human high-metastatic large cell lung cancer cell line L9981 established by our laboratory previously, and to provide cell models for studying the mechanisms and signal regulation of organ-specific metastasis of lung cancer. Materials and methods The parent lung cancer cell line, L9981-Luc, was inoculated in the armpit of nude mice. The live animal imaging system, IVIS-200, was used to detect the lung cancer organ-specific metastasis every week. When the organ-specific metastasis were established, the nude mices bearing the lung cancer were sacrificed when they became moribund. Under sterile conditions, the organs (mediastinal lymph nodes, lung, spinal column and brain with lung cancer organ-specific metastasis were removed and the metastasized nodules were dissected free of connective tissue and blood clots, and rinsed twice with medium. The metastasized nodules were finely minced using sterile scalpel blades in medium, and the cells were seeded in tissue culture dishes. Then, the cells with organ-specific metastasis potential were reinoculated into the armpit of nude mice, respectively. This processes were repeated to establish the organ-specific metastatic sublines of L9981-Luc cell line more than 10 times. Finally, the organ-specific metastasis sublines of L9981-Luc were screened and established, which the four cell lines have the characteristics only metastasized to brian, lung, bone and mediastinal lymph node.

    A 23-years old man, complaining of two weeks febrile period, general weakness, easy fatigue, breathlessness and lost of weight was admitted. Hepatomegaly, ascite, leg edema were observed. Abdominal computed tomography revealed a great number of hydatid cysts in the liver, spleen and peritoneum. The patient was treated with Albendazole, given at a dose of 10 mg/kg/day for six months. After one and half month of therapy the clinical status of the patient considerably improved, US and Computed tomography examination showed a decrease in size of the larger cysts, changes in cyst structure and disappearance of the smaller cysts. One and half year later almost ail cysts disappeared completely, the remaining represented some irregular spots with marked density. The results showed that Albendazole has rapid curative effect in patients with multiple abdominal echinococcosis. (authors)

    Iris metastasis in patients with gastric cancer is extremely rare. Herein, it is aimed to report on a patient with gastric adenocarcinoma and iris metastasis. A 65-year-old patient with the history of gastric cancer was admitted for eye pain and eye redness on his left eye. There was ciliary injection, severe +4 cells with hypopyon in the anterior chamber and a solitary, friable, yellow-white, fleshy-creamy vascularized 2 mm × 4 mm mass on the upper nasal part of the iris within the left eye. The presented patient's mass lesion in the iris fulfilled the criteria of the metastatic iris lesion's appearance. The ocular metastasis occurred during chemotherapy. Iris metastasis can masquerade as iridocyclitis with pseudohypopyon or glaucoma. In patients with a history of gastric cancer that present with an iris mass, uveitis, and high intraocular pressure, ocular metastasis of gastric cancer should be a consideration.

    In order to inhibit the growth of lung cancer bone metastasis and reduce the bone resorption at bone metastasis sites, a bone metastasis target micelle DOX@DBMs-ALN was prepared. The size and the zeta potential of DOX@DBNs-ALN were about 60 nm and -15 mV, respectively. DOX@DBMs-ALN exhibited high binding affinity with hydroxyapatite and released DOX in redox-responsive manner. DOX@DBMs-ALN was effectively up taken by A549 cells and delivered DOX to the nucleus of A549 cells, which resulted in strong cytotoxicity on A549 cells. The in vivo experimental results indicated that DOX@DBMs-ALN specifically delivered DOX to bone metastasis site and obviously prolonged the retention time of DOX in bone metastasis site. Moreover, DOX@DBMs-ALN not only significantly inhibited the growth of bone metastasis tumour but also obviously reduced the bone resorption at bone metastasis sites without causing marked systemic toxicity. Thus, DOX@DBMs-ALN has great potential in the treatment of lung cancer bone metastasis.

    In this paper, we present an autocontext model(ACM)-based automatic liver segmentation algorithm, which combines ACM, multiatlases, and mean-shift techniques to segment liver from 3-D CT images. Our algorithm is a learning-based method and can be divided into two stages. At the first stage, i.e., the training stage, ACM is performed to learn a sequence of classifiers in each atlas space (based on each atlas and other aligned atlases). With the use of multiple atlases, multiple sequences of ACM-based classifiers are obtained. At the second stage, i.e., the segmentation stage, the test image will be segmented in each atlas space by applying each sequence of ACM-based classifiers. The final segmentation result will be obtained by fusing segmentation results from all atlas spaces via a multiclassifier fusion technique. Specially, in order to speed up segmentation, given a test image, we first use an improved mean-shift algorithm to perform over-segmentation and then implement the region-based image labeling instead of the original inefficient pixel-based image labeling. The proposed method is evaluated on the datasets of MICCAI 2007 liver segmentation challenge. The experimental results show that the average volume overlap error and the average surface distance achieved by our method are 8.3% and 1.5 m, respectively, which are comparable to the results reported in the existing state-of-the-art work on liver segmentation.

    The incidence of brain metastasis from hepatocellular carcinoma (HCC) is expected to increase as a result of prolonged survival due to the recent advances in HCC treatment. However, there is no definite treatment strategy for brain metastasis from HCC mainly due to its rarity and dismal prognosis. To provide helpful recommendations in treatment of brain metastasis from HCC, the authors aimed to identify prognostic factors that influence survival rates with a review of the recently published data. Thirty-three cases of brain metastasis, whose incidence was 0.65%, were selected from a total of 5015 HCC patients and reviewed retrospectively in terms of clinical and radiological features. Median overall survival time after diagnosis of brain metastasis was 10.4 weeks (95% confidence interval [CI], 5.1-15.7 weeks) with 1-, 6- and 12-month survival rates, of 79%, 24% and 6%, respectively. Median survival of the patients treated with surgical resection or surgical resection followed by whole-brain radiation therapy (WBRT) (25.3 weeks; range, 15.8-34.8 weeks) was longer than that of the patients treated with gamma knife surgery (GKS), WBRT, or GKS followed by WBRT (10.4 weeks; range, 7.5-13.3 weeks) as well as that of patients treated with only steroids (1 week; range, 0.0-3.3 weeks) (p < 0.001). Child-Pugh’s classification A group had a longer median survival time than Child-Pugh’s classification B or C group (14.4 weeks vs 8.4 weeks, p = 0.038). RPA class I & II group had also a longer median survival time than RPA class III group did (13.4 weeks vs 2.4 weeks, p = 0.001). Surgical resection (hazard ratio [HR] 0.23, 95% CI 0.08-0.66, p = 0.006) and good liver function at the time of brain metastasis (HR 0.25, 95% CI 0.09-0.69, p = 0.007) were found to be the powerful prognostic factors for favorable survival in the multivariate analysis. In addition, presence of intratumoral hemorrhage was a statistically significant prognostic factor for survival. Although HCC

    Full Text Available Metastatic renal cell cancer is associated with poor prognosis and survival and is resistant to conventional chemotherapy. Therapeutic targeting of molecular pathways for tumor angiogenesis and other specific activation mechanisms offers improved tumor response and prolonged survival. A 48-year-old, female patient presented with large right renal mass with features suggesting of renal cell cancer without metastasis on contrast enhanced computed tomography (CT. Right radical nephrectomy was done. After 9 months of surgery, she got metastasis in lung, liver and ovary. The patient received sunitinib via an expanded access program. After eight 6-week cycles of sunitinib, a reassessment CT scan confirmed an excellent partial response with the almost complete disappearance (90% of liver and lung metastasis but the adnexal mass had increased in size (>10 times and the possibility was thought of second malignancy. Excision of the mass performed. Histopathology of the mass depicted metastatic renal cell cancer. There is possibility of a ′site-specific anti-angiogenic potentiation mechanism′ of malignancy in relation to sunitinib based upon the preclinical studies, in reference to the index case. Regression of one site with concurrent progression is possible. The exact mechanism of site-specific response, especially organ specific progression by vascular endothelial growth factor inhibitors in metastatic renal cell cancer warrants further study.

  19. Stereotactic radiotherapy for brain metastasis

    2012-01-01

    Stereotactic radiosurgery is now well implanted in the radiotherapy treatment tools of brain metastasis. The dose can be delivered in one or multiple sessions. Results seem equivalent. CT scan and MRI imaging are required to delineate and calculate dosimetry. Doses are variable according to the size of the metastases, localization, pathology or equipment. Stabilization or reduction of tumour size is the rules after stereotactic treatment. Impact in terms of overall survival is more difficult to apprehend because of the general context of the disease. Many questions remain unresolved, such as the usefulness of whole brain irradiation, adaptation of the treatment schedule to tumour pathophysiology, role of stereotactic treatment after surgery of metastases, etc. (authors)

    We reported a case of port site metastasis in a 57-year-old patient who underwent video-assisted thoracic surgery (VATS) resection of pulmonary metastasis from breast cancer. Port site metastasis after VATS is very rare in patients with breast cancer. However, when suspicious lesions are detected near the port site in patients who have undergone VATS for pulmonary metastasis, port site metastasis should be considered in the differential diagnosis.

    Primary tumors metastasizing to the oral cavity are extremely rare. Lung is one of the most common primary sources of metastases to the tongue. Although the incidence of lung cancer is increasing, tongue metastasis as the initial presentation of the tumor remains uncommon. Due to the rarity of tongue metastasis, little is known about its imaging findings. Herein we report the magnetic resonance imaging and clinical findings of a lingual metastasis, mimicking an abscess, from a primary lung cancer.

    Cutaneous metastasis is the result of malignant cell spread from primary malignancy to the skin. This is not uncommon, and rates reported in the literature are as high as 10.4%. To the best of our knowledge, there are no studies assessing the epidemiologic, clinical, and histopathological features of cutaneous metastasis in our region. To assess the clinical and histopathological findings of all patients diagnosed with cutaneous metastasis at the American University of Beirut - Medical Center (AUB-MC) and to compare our findings with those published in the literature. Retrospective clinical and histopathologic evaluation of all cases diagnosed as cutaneous metastasis at AUB-MC between 1992 and 2010. A total of 72 patients (50 females and 22 males) were identified. The mean age at diagnosis was 55.2 years. The most common primary cancer was breast cancer in women and laryngeal cancer in men. The most common clinical presentation was a single nodule in 27% of cases followed by multiple nodules in 23%. Cutaneous metastasis lesions were asymptomatic in the majority. The chest was the most commonly affected site. On microscopy, the majority of metastatic cases were adenocarcinomas (74%). This is, to our knowledge, the first study characterizing the epidemiological, clinical, and histopathological features of cutaneous metastasis in the Lebanese population. The clinical and histopathological features observed were in concordance with the published literature, with minor differences. © 2013 The International Society of Dermatology.

    Purpose: To determine specific imaging features of hepatic metastasis from colorectal cancer, focusing on the hepatobiliary phase (HBP) of gadoxetic acid-enhanced MRI. Materials and methods: Over a 2-year period, 79 hepatic metastatic lesions were identified from 32 patients (22 men and 10 women) who proven colorectal cancer and underwent gadoxetic acid-enhanced 3.0 T MRI. Hepatic metastases were proven pathologically in 16 patients: by surgical liver resection (n = 14) and by US-guided biopsy (n = 2). The remaining 16 patients were considered to have hepatic metastasis based on imaging studies and clinical information. Two radiologists evaluated the imaging features of each MRI sequence, including high resolution T2WI, dynamic contrast enhancement study with hepatobiliary phase, and diffusion weighted image. We also compared SI of the lesions on T2WI and HBP. Results: T2WI showed homogeneous high SI (n = 25; 31.7%), target appearance (n = 3; 3.8%), reversed target appearance (n = 2; 2.6%), and heterogeneously high SI (n = 49; 62%). On HBP, homogeneous defect were seen in 22 lesions (27.9%), target appearance in five lesions (6.4%), reversed target appearance in two lesions (2.5%), and heterogeneous defect in 50 lesions (63.3%); including reticular (70%), partially globular (26%), and diffuse GGO-like (4%) patterns. According to the imaging features on HBP, the homogeneous defect and heterogeneous defect groups had a mean ADC value of 0.99 × 10 −3 and 1.07 × 10 −3 mm 2 /s, respectively, without statistically significant difference. Conclusion: Hepatic metastasis from colorectal cancer usually showed as a heterogeneous defect on HBP and a heterogeneous high SI on T2WI. The generally accepted “true defect” was not a common finding in hepatic metastasis from colorectal cancer.

    It has been well known that angiosarcoma (AS), particularly scalp AS, metastasizes to the lungs with multiple air-filled cystic lesions on chest computed tomography scans. Pneumothorax, due to cystic lesion rupture into the pleural space, is frequent;however, we do not exactly know how rapidly the metastatic lesions spread to the lungs or what the exact pathogenetic mechanism for cystic metastasis is. According to our experience, the speed of disease progression in pulmonary metastasis is relatively fast and the entire lungs may be involved within two or three months. The infiltrating spindle cell tumors in the alveolar walls are tethering the adjacent alveolar spaces in order to form a dilated air-filled cystic lesion.

    The survival benefit of adjuvant chemotherapy after colorectal cancer (CRC) lung metastasectomy is uncertain. We enrolled 221 CRC patients who underwent pulmonary metastasectomy between October 2002 and July 2013, including those with previous liver metastasis that had been curatively resected. Disease-free survival (DFS) and overall survival (OS) were calculated from the day of lung metastasectomy. Among all patients, 176 (79.6%) received adjuvant chemotherapy after lung metastasectomy. Median follow-up was 34.7 months from the time of lung metastasectomy [95% confidence interval (95% CI), 7.4-90.9 months]. Patients treated with adjuvant chemotherapy had longer DFS compared with surgery alone (median 32.7 vs 11.2 months respectively, P = 0.076). Multivariate analysis revealed previous liver metastasis, preoperative carcinoembryonic antigen ≥5 ng/mL, disease-free interval chemotherapy as independent risk factors for recurrence. Low-risk patients who had 0-1 risk factors received a significant survival benefit from adjuvant chemotherapy [hazard ratio (HR) 0.54; 95% CI 0.32-0.91, P = 0.020]; however, high-risk patients with ≥2 risk factors did not (HR 1.02; 95% CI 0.48-2.14, P = 0.964). Patients treated with adjuvant chemotherapy showed no OS benefit compared with patients who received surgery alone (median 89.6 vs 86.8 months respectively, P = 0.833). CRC patients received lung metastasectomy could have a DFS benefit from adjuvant chemotherapy, especially in low-risk patients. Larger, prospective studies are needed to evaluate the role of adjuvant chemotherapy after CRC lung metastasectomy.

    Full Text Available Liver metastasis in solid tumors, including colorectal cancer, is the most frequent and lethal complication. The development of systemic therapy has led to prolonged survival. However, in selected patients with a finite number of discrete lesions in liver, defined as oligometastatic state, additional local therapies such as surgical resection, radiofrequency ablation, cryotherapy, and radiotherapy can lead to permanent local disease control and improve survival. Among these, an advance in radiation therapy made it possible to deliver high dose radiation to the tumor more accurately, without impairing the liver function. In recent years, the introduction of stereotactic ablative radiotherapy (SABR has offered even more intensive tumor dose escalation in a few fractions with reduced dose to the adjacent normal liver. Many studies have shown that SABR for oligometastases is effective and safe, with local control rates widely ranging from 50% to 100% at one or two years. And actuarial survival at one and two years has been reported ranging from 72% to 94% and from 30% to 62%, respectively, without severe toxicities. In this paper, we described the definition and technical aspects of SABR, clinical outcomes including efficacy and toxicity, and related parameters after SABR in liver oligometastases from colorectal cancer.

    PurposeThis phase II prospective study investigates possible benefits of radiofrequency ablation (RFA) combined with hepatic arterial chemoembolization using degradable starch microsphere (DSM) mixed with mitomycin C (MMC) in non-surgical candidates with colorectal liver metastases.Materials and MethodsThis study, approved by the respective institutional review board, included non-surgical candidates with 3 or fewer liver tumors of 3 cm or smaller, or a single lesion 5 cm or smaller. Percutaneous RFA was performed immediately after chemoembolization using DSM-MMC. Primary and secondary endpoints were the local tumor control rate, safety, and 2-year recurrence-free and overall survival rates.ResultsThis study examined 25 patients (22 males, 3 females) with 38 tumors of mean maximum diameter of 2.2 ± 0.9 cm (standard deviation) (range 1.0–4.2 cm). Their mean age was 70.2 ± 8.2 years (range 55–82 years). Local tumor progression developed in 3 tumors (7.9%, 3/38) of 3 patients (12%, 3/25) during the mean follow-up of 34.9 ± 9.2 months (range 18.3–50.1 months). The 2-year local tumor control rates were 92.0% [95% confidence interval (CI), 81.4–100%] on a patient basis and 94.6% (95% CI, 87.3–100%) on a tumor basis. The respective 2-year overall and recurrence-free survival rates were 88.0% (95% CI, 75.3–98.5%) and 63.3% (95% CI, 44.2–82.5%), with median survival time of 48.4 months. Fever was the only adverse event requiring treatments in 2 patients (8%).ConclusionsThis combination therapy is safe, exhibiting strong anticancer effects on colorectal liver metastasis, which might contribute to patient survival.

    Full Text Available We report an extremely rare and unusual case of retroperitoneal and pelvic metastasis from primary squamous cell carcinoma of vallecula. Generally carcinoma oropharynx metastasizes to lungs, liver and bone while retroperitoneal and pelvic metastasis is rarely heard of. To the best of our knowledge this case is one of the scantly reported cases ever of this kind in the world.  A 60-year-old male presented with dysphagia and hoarseness of voice of four month duration.  Computed tomography (CT scan face and neck showed growth right vallecula. Biopsy of lesion showed squamous cell carcinoma. Metastatic work up was negative. He received definitive chemo-radiation. Patient during follow up presented with dyspepsia, abdominal discomfort and weight loss. Whole body positron emission tomography (WB PET scan revealed retroperitoneal and pelvic lymph node deposits which were confirmed as metastasis of squamous cell carcinoma by CT guided fine needle aspiration cytology (FNAC. Patient was exhibited palliative chemotherapy but his general condition deteriorated and he finally succumbed to his metastatic illness. This case is being reported to highlight its extreme rarity, the diagnostic and therapeutic challenges it presented and its overall dismal prognosis.

    Liver transplant procedure acts as a challenge for transfusion services in terms of specialized blood components, serologic problems, and immunologic effects of transfusion. Red cell alloimmunization in patients awaiting a liver transplant complicate the process by undue delay or unavailability of compatible red blood cell units. Compatible blood units can be provided by well-equipped immunohematology laboratory, which has expertise in resolving these serological problems. This report illustrates resolution of a case with multiple alloantibodies using standard techniques, particularly rare antisera. Our case re-emphasizes the need for universal antibody screening in all patients as part of pretransfusion testing, which helps to identify atypical antibodies and plan for appropriate transfusion support well in time. We recommend that the centers, especially the ones that perform complex procedures like solid organ transplants and hematological transplants should have the necessary immunohematological reagents including rare antisera to resolve complex cases of multiple antibodies as illustrated in this case.

    Currently, it has been an international focus on intraoperative precise positioning and accurate resection of tumor and metastases. The methods such as X-rays, computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) have played an important role in preoperative accurate diagnosis. However, most of them are inapplicable for intraoperative surgery. We have proposed a surgical navigation system based on optical molecular imaging technology for intraoperative detection of tumors and metastasis. This system collects images from two CCD cameras for real-time fluorescent and color imaging. For image processing, the template matching algorithm is used for multispectral image fusion. For the application of tumor detection, the mouse breast cancer cell line 4T1-luc, which shows highly metastasis, was used for tumor model establishment and a model of matrix metalloproteinase (MMP) expressing breast cancer. The tumor-bearing nude mice were given tail vein injection of MMP 750FAST (PerkinElmer, Inc. USA) probe and imaged with both bioluminescence and fluorescence to assess in vivo binding of the probe to the tumor and metastases sites. Hematoxylin and eosin (H&E) staining was performed to confirm the presence of tumor and metastasis. As a result, one tumor can be observed visually in vivo. However liver metastasis has been detected under surgical navigation system and all were confirmed by histology. This approach helps surgeons to find orthotopic tumors and metastasis during intraoperative resection and visualize tumor borders for precise positioning. Further investigation is needed for future application in clinics.

  14. Microenvironment Determinants of Brain Metastasis

    Full Text Available Abstract Metastasis accounts for 90% of cancer-related mortality. Brain metastases generally present during the late stages in the natural history of cancer progression. Recent advances in cancer treatment and management have resulted in better control of systemic disease metastatic to organs other than the brain and improved patient survival. However, patients who experience recurrent disease manifest an increasing number of brain metastases, which are usually refractory to therapies. To meet the new challenges of controlling brain metastasis, the research community has been tackling the problem with novel experimental models and research tools, which have led to an improved understanding of brain metastasis. The time-tested "seed-and-soil" hypothesis of metastasis indicates that successful outgrowth of deadly metastatic tumors depends on permissible interactions between the metastatic cancer cells and the site-specific microenvironment in the host organs. Consistently, recent studies indicate that the brain, the major component of the central nervous system, has unique physiological features that can determine the outcome of metastatic tumor growth. The current review summarizes recent discoveries on these tumor-brain interactions, and the potential clinical implications these novel findings could have for the better treatment of patients with brain metastasis.

    We aimed to develop and assess the efficacy of a liver function index that combines liver enhancement and liver volume to standard liver volume (LV/SLV) ratio on gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid (Gd-EOB-DTPA)-enhanced MRI. In all, 111 patients underwent a Gd-EOB-DTPA-enhanced MRI, including T1 mapping, before and 20 min after Gd-EOB-DTPA administration. We calculated the following Gd-EOB-DTPA-enhanced MRI-based liver function indices: relative enhancement of the liver, corrected enhancement of the liver-to-spleen ratio, LSC{sub N}20, increase rate of the liver-to-muscle ratio, reduction rate of T1 relaxation time of the liver, ΔR1 of the liver and K{sub Hep}; the indices were multiplied by the LV/SLV ratio. We calculated the correlations between an indocyanine green (ICG) clearance and the Gd-EOB-DTPA-enhanced MRI-based liver function indices multiplied by the LV/SLV ratio, by using Pearson correlation analysis. There were significant correlations between all Gd-EOB-DTPA-enhanced MRI-based liver function indices and ICG clearance (r = -0.354 to -0.574, P < 0.001). All Gd-EOB-DTPA-enhanced MRI-based liver function indices multiplied by the LV/SLV ratio (r = -0.394 to -0.700, P < 0.001) were more strongly correlated with the ICG clearance than those without multiplication by the LV/SLV ratio. Gd-EOB-DTPA-enhanced MRI-based liver function indices that combine liver enhancement and the LV/SLV ratio may more reliably estimate liver function. (orig.)

    Full Text Available Invasive lobular carcinoma is the second most common type of invasive breast cancer accounting for approximately 5-10% of all invasive breast carcinomas. The metastatic patterns of lobular and ductal carcinomas are significantly different. Most series report a greater propensity for lobular carcinoma to metastasize to the gastrointestinal tract, gynecological organs and the peritoneum, while ductal carcinoma most frequently relapses in the liver, lungs and the brain. Gastrointestinal system metastases were observed in 6-18%, the most commonly affected organ is the stomach. We aimed to present a female patient who had been diagnosed with invasive lobular carcinoma of the breast ten years ago and had invasive ductal carcinoma of the other breast three years ago, investigated for excessive ascites and found to have invasive lobular breast carcinoma metastasis to the stomach.

  17. MicroRNA and protein profiling of brain metastasis competent cell-derived exosomes.

    Full Text Available Exosomes are small membrane vesicles released by most cell types including tumor cells. The intercellular exchange of proteins and genetic material via exosomes is a potentially effective approach for cell-to-cell communication and it may perform multiple functions aiding to tumor survival and metastasis. We investigated microRNA and protein profiles of brain metastatic (BM versus non-brain metastatic (non-BM cell-derived exosomes. We studied the cargo of exosomes isolated from brain-tropic 70W, MDA-MB-231BR, and circulating tumor cell brain metastasis-selected markers (CTC1BMSM variants, and compared them with parental non-BM MeWo, MDA-MB-231P and CTC1P cells, respectively. By performing microRNA PCR array we identified one up-regulated (miR-210 and two down-regulated miRNAs (miR-19a and miR-29c in BM versus non-BM exosomes. Second, we analyzed the proteomic content of cells and exosomes isolated from these six cell lines, and detected high expression of proteins implicated in cell communication, cell cycle, and in key cancer invasion and metastasis pathways. Third, we show that BM cell-derived exosomes can be internalized by non-BM cells and that they effectively transport their cargo into cells, resulting in increased cell adhesive and invasive potencies. These results provide a strong rationale for additional investigations of exosomal proteins and miRNAs towards more profound understandings of exosome roles in brain metastasis biogenesis, and for the discovery and application of non-invasive biomarkers for new therapies combating brain metastasis.

    Differential diagnosis between spinal metastasis and infectious spondylodiscitis is one of the occasional challenges in daily clinical practice. We encountered an unusual case of spinal metastasis in a 75-year-old female breast cancer patient that mimicked infectious spondylodiscitis. Magnetic resonance imaging (MRI) showed diffuse bone marrow infiltrations with paraspinal soft tissue infiltrative changes in 5 contiguous cervical vertebrae without significant compression fracture or cortical destruction. These MRI findings made it difficult to differentiate between spinal metastasis and infectious spondylodiscitis. Infectious spondylodiscitis such as tuberculous spondylodiscitis was regarded as the more appropriate diagnosis due to the continuous involvement of > 5 cervical vertebrae. The patient's clinical presentation also supported the presumptive diagnosis of infectious spondylodiscitis rather than spinal metastasis. Intravenous antibiotics were administered, but clinical symptoms worsened despite treatment. After pathologic confirmation by computed tomography-guided biopsy, we were able to confirm a final diagnosis of spinal metastasis

    2012-02-03

    Radiofrequency interstitial thermal ablation (RITA) provides a palliative option for patients suffering from metastatic liver disease. This procedure can be performed using a laparoscopic approach with laparoscopic ultrasound used to position the RITA probe. We describe a case of laparoscopic RITA performed for colorectal liver metastasis that was complicated by tumor lysis syndrome (TLS) following treatment. We consider RITA to be a safe procedure, as supported by the literature, but where intracorporal tumor lysis is the treatment goal we believe that the systemic release of tumor products can overwhelm the excretory capacity; therefore, TLS is an inevitable consequence in some patients.

    Objective: To evaluate the curative effect and side effects of 89 Sr therapy with radiosensitization by nicotinamide and carbogen in multiple bone metastasis of malignant neoplasms. Methods: Ninety-seven patients were divided into 4 groups respectively: group A, 89 Sr + nicotinamide + carbogen (24 patients); group B, 89 Sr + nicotinamide(22 patients); group C, 89 Sr + carbogen (25 patients); group D, 89 Sr, (26 patients). 89 SrCl was intravenously injected at a dose of 1.48-2.22 MBq/kg. Nicotinamide was taken orally 1 hour before 89 SrCl injection, 6 g/day, tid, d1-d5. Aspiration of carbogen(95%O 2 + 5%CO 2 ) gases, 6 L/min, 10 minutes, qd, d1-d5. Results: The effective rate of pain control and QOL improvement in A group were higher than in groups B, C and D (91.7% VS 77.3%, 76.0% and 69.2%, P=0.048). The lesions assessed by SPECT imaging in every group was not significantly different at three months after treatment. I to II degree toxic effect on bone marrow appeared in every group and there were no significantly inter-group differences. Conclusions: Combinative therapy using 89 Sr + nicotinamide + carbogen is more effective to treat multiple metastatic bone pain and for improvement of QOL. The side effects are not increased.

    2016-02-01

    Full Text Available Hepatocyte nuclear factor 4 alpha (HNF4α, a member of the nuclear receptor superfamily, has a high expression level in mature hepatocytes. HNF4α can regulate hepatocyte-specific gene expression at a transcriptional level, promote hepatocyte development and differentiation, participate in establishment and maintenance of hepatocyte polarity, and enhance the synthetic, metabolic, and detoxifying functions of the liver. Through inhibiting the activation of hepatic stellate cells, reversing epithelial-mesenchymal transition, and inhibiting the proliferation, invasion, and metastasis of hepatoma cells, HNF4α may be involved in the development and progression of various liver diseases including liver fibrosis, liver cirrhosis, and hepatocellular carcinoma. This paper elaborates on the biological functions of HNF4α, and summarizes and analyzes the research advances in the mechanisms of action of HNF4α in the pathological process of liver diseases, in order to provide references for further investigation of the potential targeted therapies for liver diseases.

    Full Text Available Abstract A 31-year-old man with sigmoid colon cancer with concomitant simultaneous multiple liver metastases had received FOLFIRI (leucovorin, fluorouracil and irinotecan and FOLFOX6 (leucovorin, fluorouracil and oxaliplatin after an ordinary sigmoidectomy. However, his serum carcinoembryonic antigen (CEA level increased rapidly during the fifteen months after the operation while he was on FOLFOX6. Abdominal computed tomography revealed expanding multiple liver tumors. As the third line chemotherapy, a combination therapy of cetuximab with irinotecan was given, which markedly reduced his levels of serum CEA, and the size and number of liver tumors. He underwent lateral segmentectomy of the liver and microwave coagulation of the liver metastases in the remnant liver. Thereafter, a good quality of life with tumor dormancy was obtained for 6 months. However, his serum CEA started to rise again in the absence of liver tumors. Therefore, FOLFOX6 with bevacizumab was chosen as the fourth line chemotherapy, and the serum CEA was reduced with tumor dormancy. A good quality of life was obtained again at 3 years after the first surgery. This report indicates the effectiveness of sandwiched liver surgery with the molecular targeting drugs cetuximab and bevacizumab on multiple liver metastases of colon cancer, and suggests the possibility of a regimen consisting of bevacizumab following cetuximab.

    2016-10-01

    Full Text Available Objectives: More than 24% breast cancer patients came to Sanglah Teaching Hospital with distant metastasis which cause 90% of cancer related death. Distant metastasis is complex process of interaction between tumor cells and its micro environment involving a chemoattractant cytokines which lead circulating tumor cells toward target organs. One of the most common cytokines involved in metastasis of multiple tumor is SDF-1, produces by target organ or tumor cells itselves. However, only few stucy ever evaluate the relationship between its concentrations in tumor tissue with metastasis. Method: A cross sectional analysis study was conducted involving clinical data and paraffin blocks from 46 patients. Samples were grouped into metastasis and non-metastasis group and level of tumor tissue SDF-1 was evaluated by immunohistochemistry method. Numerical conversion was done using modified “Mirisola” technique and statistical analysis was conducted using SPSS 16 software. Results: The overall median expression of SDF-1 was 4.83 in which the median is 4.08±2.25 in non-metastatic group and 5.71±2.61 in metastatic group (p=0.012. In addition, parenchymal carcinoma cell had significantly higher expression of SDF-1 compared with microenvironmental cell both in metastatic group (carcinoma cell vs microenvironment; 4,57+1,91 vs 3,68 +2,06; p=0,004 and non-metastatic group (3,19 +2,29 vs 2,16+1,11; p=0.011. Finally, logistic regression analysis of SDF-1 expression also gave significant result that MBC had significantly higher expression of SDF-1 (p=0.039.  Conclusions: There was significant association between of SDF-1 expression and distant metastasis in breast cancer and majority of SDF was produced by cancer cells

    Renal cell carcinoma (RCC) is a malignant lethal tumour with high potential of metastasis. However, metastasis from RCC to the skin is much less common. It is virtually a sign of poor prognosis. We represent a 42 years old man with bilateral RCC of clear cell type followed by metastasis to the scalp one month later. In this case the relatively young age of the patient, bilaterality of RCC and occurance of skin metastasis in the absence of recurrent kidney tumour are interesting.

    Full Text Available Many types of cancers metastasize to the eye. However, uveal melanoma metastasizing to the contralateral choroid is very rare. We report the case of a 68-year-old man with history of treated uveal melanoma of the right eye that developed metastasis to the liver and the choroid of the left eye. Ten years earlier, he was diagnosed to have uveal melanoma of the right eye and was initially treated with plaque radiotherapy. Two years later, upon progression of the disease in the right eye he had enucleation of the eye. We describe the patient’s clinical history, the diagnosis of recurrent disease in the contralateral eye, therapy of the left eye, and systemic metastasis. In addition, we reviewed the published medical literature and described the recent advances in the management of uveal melanoma.

    Phosphatase of regenerating liver-3 (PRL-3) has been proposed to promote the invasion of tumor cells to metastasis sites. However, the effect of PRL-3 on spontaneous metastasis has not been clearly demonstrated, and whether PRL-3 could become a new therapeutic target in malignant tumor is still unknown. In this study, we used PRL-3 siRNA as a molecular medicine to specifically reduce the expression of PRL-3 in B16-BL6 cells, a highly metastatic melanoma cell line. In vitro, PRL-3 siRNA significantly inhibited cell adhesion and migration, but had no effect on cell proliferation. In the spontaneous metastatic tumor model in vivo, PRL-3 siRNA treatment remarkably inhibited the proliferation of primary tumor, prevented tumor cells from invading the draining lymph nodes, and prolonged the life span of mice. Therefore, our results indicate that PRL-3 plays a critical role in promoting the whole process of spontaneous metastasis and tumor growth initiation, and that inhibiting PRL-3 will improve malignant tumor therapy.

    The study of breast cancer metastasis depends on the use of established breast cancer cell lines that do not accurately represent the heterogeneity and complexity of human breast tumors. A tumor model was developed using primary breast tumor-initiating cells isolated from patient core biopsies that would more accurately reflect human breast cancer metastasis. Tumorspheres were isolated under serum-free culture conditions from core biopsies collected from five patients with clinical diagnosis of invasive ductal carcinoma (IDC). Isolated tumorspheres were transplanted into the mammary fat pad of NUDE mice to establish tumorigenicity in vivo. Tumors and metastatic lesions were analyzed by hematoxylin and eosin (H+E) staining and immunohistochemistry (IHC). Tumorspheres were successfully isolated from all patient core biopsies, independent of the estrogen receptor α (ERα)/progesterone receptor (PR)/Her2/neu status or tumor grade. Each tumorsphere was estimated to contain 50-100 cells. Transplantation of 50 tumorspheres (1-5 × 10 3 cells) in combination with Matrigel into the mammary fat pad of NUDE mice resulted in small, palpable tumors that were sustained up to 12 months post-injection. Tumors were serially transplanted three times by re-isolation of tumorspheres from the tumors and injection into the mammary fat pad of NUDE mice. At 3 months post-injection, micrometastases to the lung, liver, kidneys, brain and femur were detected by measuring content of human chromosome 17. Visible macrometastases were detected in the lung, liver and kidneys by 6 months post-injection. Primary tumors variably expressed cytokeratins, Her2/neu, cytoplasmic E-cadherin, nuclear β catenin and fibronectin but were negative for ERα and vimentin. In lung and liver metastases, variable redistribution of E-cadherin and β catenin to the membrane of tumor cells was observed. ERα was re-expressed in lung metastatic cells in two of five samples. Tumorspheres isolated under defined culture

    Full Text Available Duodenal metastasis from renal cell carcinoma is rare, and even rarer is a massive gastrointestinal bleeding from such tumours. Coeliac occlusive disease, although rarely symptomatic, can lead to ischaemic changes with anastomotic dehiscence and leaks when a patient undergoes pancreatoduodenectomy. A 41-year-old man with known metastasis to the adrenal glands and the second part of the duodenum close to the ampulla of Vater from clear cell renal cell carcinoma was admitted to our department due to massive gastrointestinal bleeding from the duodenal metastasis. Endoscopic control of the bleed was not possible, while the bleeding vessel embolization was able to control the haemorrhage only temporarily. An angiography during the embolization demonstrated the presence of stenosis of the coeliac artery and also hypertrophic inferior pancreaticoduodenal arteries supplying the proper hepatic artery via the gastroduodenal artery (GDA. The patient underwent emergency pancreatoduodenectomy with preservation of the gastroduodenal artery. The patient had an uneventful recovery and did not experience further bleeding. Also the blood flow to the liver was compromised as shown by the normal liver function tests (LFTs postoperatively. To the best of our knowledge, this is the first report of a preservation of the GDA during an emergency pancreatoduodenectomy.

    Full Text Available Oral cavity is a rare target for metastasis with an incidence of 1% among all oral cancers. In 24% of such cases, oral metastasis is the first indication of an undiagnosed primary. Metastatic oral malignancies have been reported in the mandible, tongue, and gingiva. Although gingival metastasis has been reported from lung, prostate, rectal carcinoma in men and carcinoma of breast, adrenal glands, and genitalia in females, gingival metastasis from carcinoma of the penis has not been reported. Herein, a case of metastatic gingival carcinoma that developed after extraction of teeth from primary carcinoma of the penis is presented. An extensive literature search revealed no such similar case reports.

    S100P was recently found to be overexpressed in a variety of cancers and is considered a potential target for cancer therapy, but the functional role or mechanism of action of S100P in colon cancer is not fully understood. In the present study, we knocked down the gene expression of S100P in colon cancer cells using lentivirus-mediated RNA interference. This step resulted in significant inhibition of cancer cell growth, migration and invasion in vitro and tumor growth and liver metastasis in vivo. Moreover, S100P downstream target proteins were identified by proteomic analysis in colon cancer DLD-1 cells with deletion of S100P. Knockdown of S100P led to downregulation of thioredoxin 1 and β-tubulin and upregulation of Rho guanosine diphosphate (GDP) dissociation inhibitor α (RhoGDIA), all potential therapeutic targets in cancer. Taken together, these findings suggest that S100P plays an important role in colon tumorigenesis and metastasis, and the comprehensive and comparative analyses of proteins associated with S100P could contribute to understanding the downstream signal cascade of S100P, leading to tumorigenesis and metastasis.

    Little is known about the ability of the inflammation-based Glasgow prognostic score (GPS). 106 patients who underwent curative resection for colorectal liver metastasis (CRLM) were analyzed. Patients with an elevated Creactive protein concentration (>10 mg/L) and hypoalbuminemia (L) at admission were assigned a GPS 2, those with only 1 of these biochemical abnormalities were assigned a GPS 1, and those without either abnormality were assigned a GPS 0. Multivariate analysis showed that 2 variables, carcinoembryonic antigen (CEA) concentration > 30 ng/mL and a GPS 1 or 2, were independently prognostic of survival. Patients were classified into 3 groups on the basis of these 2 variables. Patients with GPS 1 or 2 and CEA concentration > 30 ng/mL were assigned a new score of 2, those with either 1 factor were assigned a new score of 1, and those with neither factors were assigned a new score of 0. The 5-year overall survival rates of new scores of 0, 1, 2 were 71.5%, 31.6%, and 0%, respectively (P < 0.0001). This simple staging system may be able to identify a subgroup of patients who are eligible for curative resection but show poor prognosis.

    Cancer stem cell theory indicates cancer stem cells are the key to promote tumor invasion and metastasis. Studies showed that BMI-1 could promote self-renew, differentiation and tumor formation of CSCs and invasion/metastasis of human cancer. However, whether BMI-1 could regulate invasion and metastasis ability of CSCs is still unclear. In our study, we found that up-regulated expression of BMI-1 was associated with tumor invasion, metastasis and poor survival of pancreatic cancer patients. CD133+ cells were obtained by using magnetic cell sorting and identified of CSCs properties such as self-renew, multi-differentiation and tumor formation ability. Then, we found that BMI-1 expression was up-regulated in pancreatic cancer stem cells. Knockdown of BMI-1 expression attenuated invasion ability of pancreatic cancer stem cells in Transwell system and liver metastasis capacity in nude mice which were injected CSCs through the caudal vein. We are the first to reveal that BMI-1 could promote invasion and metastasis ability of pancreatic cancer stem cells. Finally, we identified that BMI-1 expression activating PI3K/AKT singing pathway by negative regulating PTEN was the main mechanism of promoting invasion and metastasis ability of pancreatic CSCs. In summary, our findings indicate that BMI-1 could be used as the therapeutic target to inhibiting CSCs-mediated pancreatic cancer metastasis. PMID:26840020

    The incidence and mortality rate of the primary liver cancer are very high and its postoperative metastasis and recurrence have become important factors to the prognosis of patients. Circulating tumor cells (CTC), as a new tumor marker, play important roles in the early diagnosis and individualized treatment. This paper presents an effective method to distinguish liver cancer based on the cellular scattering spectrum, which is a non-fluorescence technique based on the fiber confocal microscopic spectrometer. Combining the principal component analysis (PCA) with back propagation (BP) neural network were utilized to establish an automatic recognition model for backscatter spectrum of the liver cancer cells from blood cell. PCA was applied to reduce the dimension of the scattering spectral data which obtained by the fiber confocal microscopic spectrometer. After dimensionality reduction by PCA, a neural network pattern recognition model with 2 input layer nodes, 11 hidden layer nodes, 3 output nodes was established. We trained the network with 66 samples and also tested it. Results showed that the recognition rate of the three types of cells is more than 90%, the relative standard deviation is only 2.36%. The experimental results showed that the fiber confocal microscopic spectrometer combining with the algorithm of PCA and BP neural network can automatically identify the liver cancer cell from the blood cells. This will provide a better tool for investigating the metastasis of liver cancers in vivo, the biology metabolic characteristics of liver cancers and drug transportation. Additionally, it is obviously referential in practical application.

    The fourth member of the leucine-rich repeat-containing GPCR family (LGR4, frequently referred to as GPR48) and its cognate ligands, R-spondins (RSPOs) play crucial roles in the development of multiple organs as well as the survival of adult stem cells by activation of canonical Wnt signaling. Wnt/β-catenin signaling acts to regulate breast cancer; however, the molecular mechanisms determining its spatiotemporal regulation are largely unknown. In this study, we identified LGR4 as a master controller of Wnt/β-catenin signaling-mediated breast cancer tumorigenesis, metastasis, and cancer stem cell (CSC) maintenance. LGR4 expression in breast tumors correlated with poor prognosis. Either Lgr4 haploinsufficiency or mammary-specific deletion inhibited mouse mammary tumor virus (MMTV)- PyMT- and MMTV- Wnt1-driven mammary tumorigenesis and metastasis. Moreover, LGR4 down-regulation decreased in vitro migration and in vivo xenograft tumor growth and lung metastasis. Furthermore, Lgr4 deletion in MMTV- Wnt1 tumor cells or knockdown in human breast cancer cells decreased the number of functional CSCs by ∼90%. Canonical Wnt signaling was impaired in LGR4-deficient breast cancer cells, and LGR4 knockdown resulted in increased E-cadherin and decreased expression of N-cadherin and snail transcription factor -2 ( SNAI2) (also called SLUG), implicating LGR4 in regulation of epithelial-mesenchymal transition. Our findings support a crucial role of the Wnt signaling component LGR4 in breast cancer initiation, metastasis, and breast CSCs.-Yue, Z., Yuan, Z., Zeng, L., Wang, Y., Lai, L., Li, J., Sun, P., Xue, X., Qi, J., Yang, Z., Zheng, Y., Fang, Y., Li, D., Siwko, S., Li, Y., Luo, J., Liu, M.

    CD200 is a cell surface glycoprotein that functions through engaging CD200R on cells of the myeloid lineage and inhibits their functions. Expression of CD200 was implicated in a variety of human cancer cells, including melanoma cells; however, its roles in tumor growth and immunity are not clearly understood. In this study, we used CD200R-deficient mice and the B16 tumor model to evaluate this issue. We found that CD200R-deficient mice exhibited accelerated growth of CD200(+), but not CD200(-), B16 tumors. Strikingly, CD200R-deficient mice receiving CD200(+) B16 cells i.v. exhibited massive tumor growth in multiple organs, including liver, lung, kidney, and peritoneal cavity, whereas the growth of the same tumors in wild-type mice was limited. CD200(+) tumors grown in CD200R-deficient mice contained higher numbers of CD11b(+)Ly6C(+) myeloid cells, exhibited increased expression of VEGF and HIF1α genes with increased angiogenesis, and showed significantly reduced infiltration of CD4(+) and CD8(+) T cells, presumably as the result of reduced expression of T cell chemokines, such as CXCL9 and CXCL16. The liver from CD200R-deficient mice, under metastatic growth of CD200(+) tumors, contained significantly increased numbers of CD11b(+)Gr1(-) myeloid cells and Foxp3(+) regulatory T cells and reduced numbers of NK cells. Liver T cells also had a reduced capacity to produce IFN-γ or TNF-α. Taken together, we revealed a critical role for CD200R signaling in limiting the growth and metastasis of CD200(+) tumors. Thus, targeting CD200R signaling may potentially interfere with the metastatic growth of CD200(+) tumors, like melanoma. Copyright © 2016 by The American Association of Immunologists, Inc.

    A wandering liver has been described throughout modern medical literature as a rare entity. During the last few years, an increasing number of cases have been reported associated with colonic volvulus. We report a 17-year-old with a hypermobile liver seen on multiple radiographs and CT. The intraoperative findings demonstrated the liver in its normal anatomic position. We suggest that this entity is more common than thought, and the rise in incidence is likely secondary to increased utilization of pre-operative imaging of patients with colonic obstruction. Increased suspicion might result in further increased incidence of this exceedingly rare entity. (orig.)

    2016-01-01

    Radioembolization with 90 Y-loaded microspheres is increasingly used in the treatment of primary and secondary liver cancer. Technetium-99 m macroaggregated albumin (MAA) scintigraphy is used as a surrogate of microsphere distribution to assess lung or digestive shunting prior to therapy, based on tumoral targeting and dosimetry. To date, this has been the sole pre-therapeutic tool available for such evaluation. Several dosimetric approaches have been described using both glass and resin microspheres in hepatocellular carcinoma (HCC) and liver metastasis. Given that each product offers different specific activities and numbers of spheres injected, their radiobiological properties are believed to lightly differ. This paper summarizes and discusses the available studies focused on MAA-based dosimetry, particularly concentrating on potential confounding factors like clinical context, tumor size, cirrhosis, previous or concomitant therapy, and product used. In terms of the impact of tumoral dose in HCC, the results were concordant and a response relationship and tumoral threshold dose was clearly identified, especially in studies using glass microspheres. Tumoral dose has also been found to influence survival. The concept of treatment intensification has recently been introduced, yet despite several studies publishing interesting findings on the tumor dose-metastasis relationship, no consensus has been reached, and further clarification is thus required. Nor has the maximal tolerated dose to the liver been well documented, requiring more accurate evaluation. Lung dose was well described, despite recently identified factors influencing its evaluation, requiring further assessment. MAA SPECT/CT dosimetry is accurate in HCC and can now be used in order to achieve a fully customized approach, including treatment intensification. Yet further studies are warranted for the metastasis setting and evaluating the maximal tolerated liver dose. (orig.)

  3. Reactive Astrocytes in Brain Metastasis

    2017-12-01

    Full Text Available Brain metastasis, the secondary growth of malignant cells within the central nervous system (CNS, exceeds the incidence of primary brain tumors (i.e., gliomas by tenfold and are seemingly on the rise owing to the emergence of novel targeted therapies that are more effective in controlling extracranial disease relatively to intracranial lesions. Despite the fact that metastasis to the brain poses a unmet clinical problem, with afflicted patients carrying significant morbidity and a fatal prognosis, our knowledge as to how metastatic cells manage to adapt to the tissue environment of the CNS remains limited. Answering this question could pave the way for novel and more specific therapeutic modalities in brain metastasis by targeting the specific makeup of the brain metastatic niche. In regard to this, astrocytes have emerged as the major host cell type that cancer cells encounter and interact with during brain metastasis formation. Similarly to other CNS disorders, astrocytes become reactive and respond to the presence of cancer cells by changing their phenotype and significantly influencing the outcome of disseminated cancer cells within the CNS. Here, we summarize the current knowledge on the contribution of reactive astrocytes in brain metastasis by focusing on the signaling pathways and types of interactions that play a crucial part in the communication with cancer cells and how these could be translated into innovative therapies.

  4. Pediatric Non-Alcoholic Fatty Liver Disease

    2017-06-01

    Full Text Available Abstract: With the increase in the prevalence of obesity, non-alcoholic fatty liver disease (NAFLD has become among the leading causes of chronic liver disease in the pediatric age group. Once believed to be a “two-hit process”, it is now clear that the actual pathophysiology of NAFLD is complex and involves multiple pathways. Moreover, NAFLD is not always benign, and patients with non-alcoholic steatohepatitis (NASH are at increased risk of developing advanced stages of liver disease. It has also been shown that NAFLD is not only a liver disease, but is also associated with multiple extrahepatic manifestations, including cardiovascular diseases, type 2 diabetes, and low bone mineral density. Although the data is scarce in the pediatric population, some studies have suggested that long-term mortality and the requirement of liver transplantation will continue to increase in patients with NAFLD. More studies are needed to better understand the natural history of NAFLD, especially in the pediatric age group.

    Cancer stem cells (CSCs), which are highly differentiated and self-renewing, play an important role in the occurrence, therapeutic resistant and metastasis of hepatacellular carcinoma (HCC). Oncolytic adenoviruses have targeted killing effect on tumor cells, and are invoked as candidate drugs for cancer treatment. We designed a dual-regulated oncolytic adenovirus Ad.wnt-E1A(△24bp)-TSLC1 that targets Wnt and Rb signaling pathways respectively, and carries the tumor suppressor gene, TSLC1. Previous studies have demonstrated that oncolytic adenovirus mediated TSLC1can target liver cancer and exhibit significant cytotoxicity. However, whether Ad.wnt-E1A(△24bp)-TSLC1 can effectively eliminate liver CSCs remains to be explored. We first used the spheroid culture to enrich the liver CSCs-like cells, and detected the self-renewal capacity, differentiation, drug resistance and tumorigenicity. The results showed that Ad-wnt-E1A(△24bp)-TSLC1 could effectively lead to autophagic death. In addition, recombinant adenovirus effectively induced the apoptosis, inhibit metastasis of hepatic CSCs-like cells in vivo. Further animal experiments indicated that Ad-wnt-E1A(△24bp)-TSLC1could effectively inhibit the growth of transplanted tumor of hepatic CSCs and prolong the survival time of mice. Therefore, the novel oncolytic adenovirus Ad.wnt-E1A(△24bp)-TSLC1 has potential application as a therapeutic target for HCC stem cells. Copyright © 2017 Elsevier Inc. All rights reserved.

  6. Clinical significance of lymph node metastasis in gastric cancer

    2014-01-01

    Gastric cancer, one of the most common malignancies in the world, frequently reveals lymph node, peritoneum, and liver metastases. Most of gastric cancer patients present with lymph node metastasis when they were initially diagnosed or underwent surgical resection, which results in poor prognosis. Both the depth of tumor invasion and lymph node involvement are considered as the most important prognostic predictors of gastric cancer. Although extended lymphadenectomy was not considered a survival benefit procedure and was reported to be associated with high mortality and morbidity in two randomized controlled European trials, it showed significant superiority in terms of lower locoregional recurrence and disease related deaths compared to limited lymphadenectomy in a 15-year follow-up study. Almost all clinical investigators have reached a consensus that the predictive efficiency of the number of metastatic lymph nodes is far better than the extent of lymph node metastasis for the prognosis of gastric cancer worldwide, but other nodal metastatic classifications of gastric cancer have been proposed as alternatives to the number of metastatic lymph nodes for improving the predictive efficiency for patient prognosis. It is still controversial over whether the ratio between metastatic and examined lymph nodes is superior to the number of metastatic lymph nodes in prognostic evaluation of gastric cancer. Besides, the negative lymph node count has been increasingly recognized to be an important factor significantly associated with prognosis of gastric cancer. PMID:24744586

    DNA polymerase iota (Pol ι) is an error-prone DNA polymerase involved in translesion DNA synthesis (TLS) that contributes to the accumulation of DNA mutations. We recently showed that Pol ι is overexpressed in human esophageal squamous cell cancer (ESCC) tissues which promotes ESCC' progression. The present study was aimed at investigating the molecular mechanisms by which Pol ι enhances the invasiveness and metastasis of ESCC cells. We found that the expression of Pol ι is significantly higher in ESCCs with lymph node metastasis compared to those without lymph node metastasis. Kaplan-Meier analysis revealed an inverse correlation between Pol ι expression and patient prognosis. The expression levels of matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9), two essential regulators of cells' invasiveness, were positively associated with Pol ι expression in ESCC tissues. Ectopic expression of Pol ι enhanced the motility and invasiveness of ESCC cells as evaluated by wound-healing and transwell assays, respectively. A xenograft nude mouse model showed that Pol ι promotes the colonization of ESCC cells in the liver, lung and kidney. Signaling pathway analysis identified the JNK-AP-1 cascade as a mediator of the Pol ι-induced increase in the expression of MMP-2/9 and enhancement of ESCC progression. These data demonstrate the underlying mechanism by which Pol ι promotes ESCC progression, suggesting that Pol ι is a potential novel prognostic biomarker and therapeutic target for ESCC.

    Hepatic elimination of epidermal growth factor (EGF) via receptor-mediated endocytosis was studied by a multiple-indicator dilution method in the isolated perfused rat liver, in which cell polarity and spatial organization are maintained. In this method EGF was given with inulin, an extracellular reference, as a bolus into the portal vein, and dilution curves of both compounds in the hepatic vein effluent were analyzed. Analysis of the dilution curve for EGF, compared with that for somatostatin, which showed no specific binding to isolated liver plasma membranes, resulted as follows: (i) both extraction ratio and distribution volume of 125 I-labeled EGF decreased as the injected amount of unlabeled EGF increased; (ii) the ratio plot of the dilution curve for EGF exhibited an upward straight line initially for a short period of time, whereas the ratio plot of somatostatin gradually decreased. The multiple-indicator dilution method was used for other peptides also. Insulin and glucagon, known to have hepatocyte receptors, behaved similarly to EGF in shape of their ratio plots. The kinetic parameters calculated by this analysis were comparable with reported values obtained by in vitro direct binding measurements at equilibrium using liver homogenates. They conclude that the multiple-indicator dilution method is a good tool for analyzing the dynamics of peptide hormones-cell-surface receptor interaction under a condition in which spatial architecture of the liver is maintained

    Although [ 18 F]fluorothymidine positron emission tomography (FLT-PET) permits estimation of tumor thymidine kinase-1 expression, and thus, cell proliferation, high physiological uptake of tracer in liver tissue can limit its utility. We evaluated FLT-PET combined with a temporal-intensity information-based voxel-clustering approach termed kinetic spatial filtering (FLT-PET KSF ) for detecting drug response in liver metastases. FLT-PET and computed tomography data were collected from patients with confirmed breast or colorectal liver metastases before, and two weeks after the first cycle of chemotherapy. Changes in tumor FLT-PET and FLT-PET KSF variables were determined. Visual distinction between tumor and normal liver was seen in FLT-PET KSF images. Of the 33 metastases from 20 patients studied, 26 were visible after kinetic filtering.

    Cancer-specific alterations in DNA methylation are hallmarks of human malignancies; however, the nature of the breast cancer epigenome and its effects on metastatic behavior remain obscure. To address this issue, we used genome-wide analysis to characterize the methylomes of breast cancers with diverse metastatic behavior. Groups of breast tumors were characterized by the presence or absence of coordinate hypermethylation at a large number of genes, demonstrating a breast CpG island methylator phenotype (B-CIMP). The B-CIMP provided a distinct epigenomic profile and was a strong determinant of metastatic potential. Specifically, the presence of the B-CIMP in tumors was associated with low metastatic risk and survival, and the absence of the B-CIMP was associated with high metastatic risk and death. B-CIMP loci were highly enriched for genes that make up the metastasis transcriptome. Methylation at B-CIMP genes accounted for much of the transcriptomal diversity between breast cancers of varying prognosis, indicating a fundamental epigenomic contribution to metastasis. Comparison of the loci affected by the B-CIMP with those affected by the hypermethylator phenotype in glioma and colon cancer revealed that the CIMP signature was shared by multiple human malignancies. Our data provide a unifying epigenomic framework linking breast cancers with varying outcome and transcriptomic changes underlying metastasis. These findings significantly enhance our understanding of breast cancer oncogenesis and aid the development of new prognostic biomarkers for this common malignancy. PMID:21430268

    This paper describes bases of radiotherapy (RT) of liver cancer for its application, efficacy, clinical target volume (CTV) and characteristics, dose fractionation and its theory, 2D/3D irradiation, evaluation, and safety. The description here is leading to execute the Guideline 200X to be issued in a near future by the Japanese College of Radiology, and is supplementary to the Guideline in nature. The Guideline is to incorporate the recent progresses of the therapy to complement the previous Guideline 2004. Thus here are described the application of RT to unresectable hepatoma in relation to intervention; characteristics of RT including dose-effect relationships, morphological characteristics of intravascular tumor thrombi (ITT) and CTV, dose fractionation and a/b ratio (liver 2.5 vs hepatoma 7.4), focal lesion in parenchyma, ITT and RT, lymph metastasis, arteriovenous shunt and dissemination, and desensitization in bone and adrenal metastases; prediction of radiation liver damage; and adverse effect by radiation and its control. The evidenced bases of RT are still poor in this field, but the fact that hepatoma, highly sensitive to radiation, exhibits clear dose-response ensures its efficacy if the problems of low tolerance and of breathing movement at irradiation can be solved.

    Benign schwannomas, also referred to as neurilemomas, neurinomas, and perineural fibroblastomas, are encapsulated nerve sheath tumors. Primary schwannomas of the liver are extremely rare. We present a case of liver schwannoma, incidentally found in a patient with breast cancer. A 66-year-old female consulted her physician for a mass she palpated on her left breast. The abdominal ultrasonography (USG) revealed a 44 x 28 mm mass in the medial segment of the left lobe of her liver suspicious of a metastasis. An USG-guided biopsy was performed and the histo-pathological examination revealed a "peripheral nerve sheath tumor". Positron emission tomography (PET-CT) revealed a pathologic FDG uptake in the lesion that was previously defined in the liver. The tumor resected from the liver was 5 x 4 x 3 cm, yellowish, soft, and capsulated tumor. Microscopic examination revealed that the mass consisted of bundles of spindle cells with hypercellular and hypocellular areas. In immunohistochemistry, there was a strong positive staining for S-100. The tumor was diagnosed as benign liver schwannoma. Schwannomas are benign, encapsulated neoplasms. Symptoms and signs vary depending on the anatomical site and the size of the neoplasm; however, most schwannomas present as an asymptomatic or painless mass. Recurrence is unusual, despite of an incomplete removal, and malignant transformation is exceedingly rare (Fig. 4, Ref. 8). Full Text (Free, PDF) www.bmj.sk.

    Quantitative assessment of hepatic and splenic blood flow detected by injecting Tc-99m-Sn colloid as a bolus was performed on 75 patients who were suspected of having liver disease. Using a computer, the hepatic and splenic time-activity curves were analyzed. Hepatic index was calculated as the ratio of arterial to portal blood flow. The peak time of the right kidney was corresponded to the junction of the arterial and portal phases of the hepatic curve. Splenic index was calculated as the ratio of splenic arterial to liver arterial blood flow. Hepatic and splenic indices had elevated in cases of liver cirrhosis and hepatoma than those of normal controls. There was no significant difference in the hepatic and splenic indices among chronic hepatitis, liver metastasis and normal subject. These noninvasive tests for the hepatic and splenic blood flow may be useful in writing a report of liver scintigram because of the added information of the liver. (author)

    We evaluated wedged-shaped, segmental changes in the liver caused by occlusion of a single hepatic vein in seven patients. The causes of occlusion were due to liver tumors in three patients, metastasis of the right adrenal gland in one, and postoperative changes in three. Changes included low attenuating on unenhanced CT, high attenuation on enhanced CT, low signal intensity on T1-weighted MRI, high signal intensity on T2-weighted MRI, high signal intensity on enhanced MRI, dense hepatogram and retrograde arterioportal shunt on hepatic arteriography. MRI and hepatic arteriography are more sensitive than CT in demonstration of those changes. (author)

    Many diseases, especially cancer, are not static, but rather can be summarized by a series of events or stages (e.g. diagnosis, remission, recurrence, metastasis, death). Most available methods to analyze multi-stage data ignore intermediate events and focus on the terminal event or consider (time to) multiple events as independent. Competing-risk or semi-competing-risk models are often deficient in describing the complex relationship between disease progression events which are driven by a shared progression stochastic process. A multi-stage model can only examine two stages at a time and thus fails to capture the effect of one stage on the time spent between other stages. Moreover, most models do not account for latent stages. We propose a semi-parametric joint model of diagnosis, latent metastasis, and cancer death and use nonparametric maximum likelihood to estimate covariate effects on the risks of intermediate events and death and the dependence between them. We illustrate the model with Monte Carlo simulations and analysis of real data on prostate cancer from the SEER database.

    INTRODUCTION: Colorectal carcinoma accounts for 10% of cancer deaths in the Western World, with the liver being the most common site of distant metastases. Resection of liver metastases is the treatment of choice, with a 5-year survival rate of 35%. However, only 5-10% of patients are suitable for resection at presentation. AIMS: To examine the referral pattern of patients with liver metastases to a specialist hepatic unit for resection. METHODOLOGY: Retrospective review of patient\\'s charts diagnosed with colorectal liver metastases over a 10-year period. RESULTS: One hundred nine (38 women, 71 men) patients with liver metastases were included, mean age 61 years; 79 and 30 patients had synchronous and metachronus metastases, respectively. Ten criteria for referral were identified; the referral rate was 8.25%, with a resection rate of 0.9%. Forty two percent of the patients had palliative chemotherapy; 42% had symptomatic treatment. CONCLUSION: This study highlights the advanced stage of colorectal cancer at presentation; in light of modern evidence-based, centre-oriented therapy of liver metastasis, we conclude that criteria of referral for resection should be based on the availability of treatment modalities.

    A case of treatment-related leukoencephalopathy is presented. A patient with breast cancer metastasis to the brain, liver, bone and distant lymph nodes was treated with whole brain radiation and docetaxcel. Eleven months after radiation, magnetic resonance imaging showed diffuse leukoencephalopathy. Twenty-two months after radiation, the patient had gait disturbance, parkinsonism, dementia and urinary incontinence. From this experience, stereotactic radiosurgery such as cyber knife and gamma knife therapy, representing a new modality for delivering intense focal radiation, should be come preferred techniques for treating patients with brain metastases, to avoid the potential cognitive side effects of fractionated whole-brain radiotherapy.

    Full Text Available Antineoplastons are naturally occurring peptides and amino acid derivatives found in human blood and urine. Antineoplaston A10 and AS2-1 reportedly control neoplastic growth and do not significantly inhibit normal cell growth. Antineoplastons contain 3-phenylacetylamino-2, 6-piperidinedione (A10, phenylacetylglutamine plus phenylacetylisoglutamine (A10-I, and phenylacetylglutamine plus phenylacetate (AS2-1. This open label, non- blinded randomized phase II study compared the efficacy of hepatic arterial infusion (HAI with 5-fluorouracil,with or without antineoplastons as a postoperative therapy for colorectal metastasis to the liver.Sixty-five patients with histologically confirmed metastatic colon adenocarcinoma in liver, who had undergone hepatectomy, and/or thermal ablation for liver metastases were enrolled between 1998- 2004 in Kurume University Hospital. Patients were randomly assigned to receive systemic antineoplastons (A10-I infusion followed by per-oral AS2-1 plus HAI (AN arm or HAI alone (control arm based on the number of metastases and presence/ absence of extra-hepatic metastasis at the time of surgery. Primary endpoint was cancer-specific survival (CSS; secondary endpoints were relapse-free survival (RFS, status and extent of recurrence, salvage surgery (rate and toxicity.Overall survival was not statistically improved (p=0.105 in the AN arm (n=32. RFS was not significant (p=0.343. Nevertheless, the CSS rate was significantly higher in the AN arm versus the control arm (n=33 with a median survival time 67 months (95%CI 43-not calculated versus 39 months (95%CI 28-47 (p=0.037 and 5 year CSS rate 60% versus 32% respectively. Cancer recurred more often in a single organ than in multiple organs in the AN arm versus the control arm. The limited extent of recurrent tumours in the AN arm meant more patients remained eligible for salvage surgery. Major adverse effects of antineoplastons were fullness of the stomach and phlebitis.

    The incidence of bone metastasis has been increasing in all cancers in recent years. Bone metastasis is associated with substantial morbidity, including bone pain, pathological fracture, neurological deficit and/or hypercalcemia. Thus, the management of bone metastasis in patients is a clinically significant issue. In the process of bone metastasis, the primary mechanism responsible for bone destruction is cancer cell-mediated stimulation of osteoclastic bone resorption, which results in osteolysis and release of various growth factors from the bone matrix. These growth factors are prerequisites for successful colonization and subsequent invasive growth of cancer cells in bone, which is called a 'vicious cycle.' Thus, it is important to elucidate what molecules are involved in this step of bone destruction, and the understanding of these molecular mechanisms could lead to develop molecular-target therapies for bone metastasis. Bisphosphonates introduced in the treatment for bone metastasis have been shown to reduce skeletal morbidity. In Japan, the most potent bisphosphonate, zoledronate (ZOMETA), was introduced in this past April, and a phase III clinical trial of humanized anti-receptor activator of NF-κB ligand (RANKL) monoclonal antibody (Denosumab) against bone metastasis is under way as a global study. These new agents, which are targeted to osteoclasts, are considered to be standard management in the care of bone metastasis patients in combination with chemotherapy and/or hormone therapy.

    We report a case of a 39-year-old man with intractable multifocal pain caused by metastatic urachal carcinoma to the bone. The patient underwent a partial cystectomy in May 2008, and lung metastasis occurred 9 months after the surgery. He then received salvage chemotherapy, but developed metastasis to the liver, brain, and bone. He was hospitalized due to a shoulder pain, a lower back pain, buttocks pain, numbness in both legs, and drop foot in right leg. MRI revealed metastases to the spine, and lumbar spinal canal stenosis with cauda equina compression. Even a combination of fentanyl-patch, oral acetaminophen, gabapentin and paroxetine was not effective for pain control. Strontium-89 therapy and subarachnoid phenol block successfully eliminated intractable pain. The patient could be discharged from hospital and received a palliative care at home for a short period of time. (author)

    Full Text Available The incidence of melanoma, the most aggressive and life-threatening form of skin cancer, has significantly risen over recent decades. Therefore, it is essential to identify the mechanisms that underlie melanoma tumorigenesis and metastasis and to explore novel and effective melanoma treatment strategies. Accumulating evidence s uggests that aberrantly expressed long noncoding RNAs (lncRNAs have vital functions in multiple cancers. However, lncRNA functions in melanoma tumorigenesis and metastasis remain unclear. In this study, we investigated lncRNA and messenger RNA (mRNA expression profiles in primary melanomas, metastatic melanomas and normal skin samples from the Gene Expression Omnibus database. We used GSE15605 as the training set (n = 74 and GSE7553 as the validation set (n = 58. In three comparisons (primary melanoma versus normal skin, metastatic melanoma versus normal skin, and metastatic melanoma versus primary melanoma, 178, 295 and 48 lncRNAs and 847, 1758, and 295 mRNAs were aberrantly expressed, respectively. We performed Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analyses to examine the differentially expressed mRNAs, and potential core lncRNAs were predicted by lncRNA-mRNA co-expression networks. Based on our results, 15 lncRNAs and 144 mRNAs were significantly associated with melanoma tumorigenesis and metastasis. A subsequent analysis suggested a critical role for a five-lncRNA signature during melanoma tumorigenesis and metastasis. Low expression of U47924.27 was significantly associated with decreased survival of patients with melanoma. To the best of our knowledge, this study is the first to explore the expression patterns of lncRNAs and mRNAs during melanoma tumorigenesis and metastasis by re-annotating microarray data from the Gene Expression Omnibus (GEO microarray dataset. These findings reveal potential roles for lncRNAs during melanoma tumorigenesis and metastasis and provide a rich candidate

    Full Text Available ObjectiveTo investigate the expression of liver-intestine (LI-cadherin in hepatocellular carcinoma (HCC by tissue microarray and explore its relationship with pathologic features of HCC patients. MethodsSeventy primary HCC resection samples with different indexing and five primary normal tissue samples were assessed by tissue microarray and immunohistochemistry based on the SP method. The detected expression levels of LI-cadherin were compared to the clinic pathologic parameters of the tissue donors. ResultsLI-cadherin expression was detected in 39 (55.7% of the 70 primary HCC tissues, and none of the normal tissues. Positivity for LI-cadherin expression was significantly associated with lymph node metastasis and venous invasion (both P<0.05, but no significant association was observed with age, sex, tumor grade, or metastasis (all P>0.05. ConclusionLI-cadherin expression may be associated with HCC occurrence, tumor invasion, and metastasis. Future studies should assess the potential of LI-cadherin expression as a diagnostic biomarker or target of molecular therapy for HCC.

    Full Text Available Abstract Background Liver cancr is a heterogeneous disease in terms of etiology, biologic and clinical behavior. Very little is known about how many genes concur at the molecular level of tumor development, progression and aggressiveness. To explore the key genes involved in the development of liver cancer, we established a rat model induced by diethylnitrosamine to investigate the gene expression profiles of liver tissues during the transition to cirrhosis and carcinoma. Methods A rat model of liver cancer induced by diethylnitrosamine was established. The cirrhotic tissue, the dysplasia nodules, the early cancerous nodules and the cancerous nodules from the rats with lung metastasis were chosen to compare with liver tissue of normal rats to investigate the differential expression genes between them. Affymetrix GeneChip Rat 230 2.0 arrays were used throughout. The real-time quantity PCR was used to verify the expression of some differential expression genes in tissues. Results The pathological changes that occurred in the livers of diethylnitrosamine-treated rats included non-specific injury, fibrosis and cirrhosis, dysplastic nodules, early cancerous nodules and metastasis. There are 349 upregulated and 345 downregulated genes sharing among the above chosen tissues when compared with liver tissue of normal rats. The deregulated genes play various roles in diverse processes such as metabolism, transport, cell proliferation, apoptosis, cell adhesion, angiogenesis and so on. Among which, 41 upregulated and 27 downregulated genes are associated with inflammatory response, immune response and oxidative stress. Twenty-four genes associated with glutathione metabolism majorly participating oxidative stress were deregulated in the development of liver cancer. There were 19 members belong to CYP450 family downregulated, except CYP2C40 upregulated. Conclusion In this study, we provide the global gene expression profiles during the development and

    2014-01-01

    Full Text Available As the most challenging human malignancies, pancreatic cancer is characterized by its insidious symptoms, low rate of surgical resection, high risk of local invasion, metastasis and recurrence, and overall dismal prognosis. Lymphatic metastasis, above all, is recognized as an early adverse event in progression of pancreatic cancer and has been described to be an independent poor prognostic factor. It should be noted that the occurrence of lymphatic metastasis is not a casual or stochastic but an ineluctable and designed event. Increasing evidences suggest that metastasis-initiating cells (MICs and the microenvironments may act as a double-reed style in this crime. However, the exact mechanisms on how they function synergistically for this dismal clinical course remain largely elusive. Therefore, a better understanding of its molecular and cellular mechanisms involved in pancreatic lymphatic metastasis is urgently required. In this review, we will summarize the latest advances on lymphatic metastasis in pancreatic cancer.

    We reported that knockdown of the antisense noncoding mitochondrial RNAs (ASncmtRNAs) induces apoptotic death of several human tumor cell lines, but not normal cells, suggesting this approach for selective therapy against different types of cancer. In order to translate these results to a preclinical scenario, we characterized the murine noncoding mitochondrial RNAs (ncmtRNAs) and performed in vivo knockdown in syngeneic murine melanoma models. Mouse ncmtRNAs display structures similar to the human counterparts, including long double-stranded regions arising from the presence of inverted repeats. Knockdown of ASncmtRNAs with specific antisense oligonucleotides (ASO) reduces murine melanoma B16F10 cell proliferation and induces apoptosis in vitro through downregulation of pro-survival and metastasis markers, particularly survivin. For in vivo studies, subcutaneous B16F10 melanoma tumors in C57BL/6 mice were treated systemically with specific and control antisense oligonucleotides (ASO). For metastasis studies, tumors were resected, followed by systemic administration of ASOs and the presence of metastatic nodules in lungs and liver was assessed. Treatment with specific ASO inhibited tumor growth and metastasis after primary tumor resection. In a metastasis-only assay, mice inoculated intravenously with cells and treated with the same ASO displayed reduced number and size of melanoma nodules in the lungs, compared to controls. Our results suggest that ASncmtRNAs could be potent targets for melanoma therapy. To our knowledge, the ASncmtRNAs are the first potential non-nuclear targets for melanoma therapy.

    The SDF-1 receptor CXCR4 has been associated with early metastasis and poorer prognosis in breast cancers, especially the most aggressive triple-negative subtype. In line with previous reports, we found that tumoral CXCR4 expression in patients with locally advanced breast cancer was associated with increased metastases and rapid tumor progression. Moreover, high CXCR4 expression identified a group of bone marrow-disseminated tumor cells (DTC)-negative patients at high risk for metastasis and death. The protein epitope mimetic (PEM) POL5551, a novel CXCR4 antagonist, inhibited binding of SDF-1 to CXCR4, had no direct effects on tumor cell viability, but reduced migration of breast cancer cells in vitro. In two orthotopic models of triple-negative breast cancer, POL5551 had little inhibitory effect on primary tumor growth, but significantly reduced distant metastasis. When combined with eribulin, a chemotherapeutic microtubule inhibitor, POL5551 additively reduced metastasis and prolonged survival in mice after resection of the primary tumor compared with single-agent eribulin. Hypothesizing that POL5551 may mobilize tumor cells from their microenvironment and sensitize them to chemotherapy, we used a "chemotherapy framing" dosing strategy. When administered shortly before and after eribulin treatment, three doses of POL5551 with eribulin reduced bone and liver tumor burden more effectively than chemotherapy alone. These data suggest that sequenced administration of CXCR4 antagonists with cytotoxic chemotherapy synergize to reduce distant metastases. ©2015 American Association for Cancer Research.

    Cancer cells display altered glucose metabolism characterized by a preference for aerobic glycolysis. The aerobic glycolytic phenotype of hepatocellular carcinoma (HCC) is often correlated with tumor progression and poorer clinical outcomes. However, the issue of whether glycolytic metabolism influences metastasis in HCC remains unclear. In the current study, we showed that knockdown of taurine up-regulated gene 1 (TUG1) induces marked inhibition of cell migration, invasion, and glycolysis through suppression of microRNA (miR)-455-3p. MiR-455-3p, which is transcriptionally repressed by p21, directly targets the 3' untranslated region of adenosine monophosphate-activated protein kinase subunit beta 2 (AMPKβ2). The TUG1/miR-455-3p/AMPKβ2 axis regulates cell growth, metastasis, and glycolysis through regulation of hexokinase 2 (HK2). TUG1 is clearly associated with HK2 overexpression and unfavorable prognosis in HCC patients. Our data collectively highlight that novel regulatory associations among TUG1, miR-455-3p, AMPKβ2, and HK2 are an important determinant of glycolytic metabolism and metastasis in HCC cells and support the potential utility of targeting TUG1/HK2 as a therapeutic strategy for HCC.

    Liver-specific MRI is a fast-growing field, with technological and protocol advancements providing more robust imaging and allowing a greater depth of information per examination. This article reports the evidence for, and expert thinking on, current challenges in liver-specific MRI, as discussed at the 7th International Forum for Liver MRI, which was held in Shanghai, China, in October 2013. Topics discussed included the role of gadoxetic acid-enhanced MRI in the differentiation of focal nodular hyperplasia from hepatocellular adenoma and small hepatocellular carcinoma (HCC) from small intrahepatic cholangiocarcinoma (in patients with chronic liver disease), the differentiation of low-grade dysplastic nodule (DN) from pre-malignant high-grade DN and early HCC, and treatment planning and assessment of treatment response for patients with HCC and colorectal liver metastasis. Optimization of the gadoxetic acid-enhanced MRI protocol to gain robust arterial and hepatobiliary phase images was also discussed. Gadoxetic acid-enhanced MRI demonstrates added value for the detection and characterization of focal liver lesions and shows promise in a number of new indications, including regional liver functional assessment and patient monitoring after therapy; however, more data are needed in some areas, and further developments are needed to translate cutting-edge techniques into clinical practice.

    Drug-induced liver injury has been associated with the generation of reactive metabolites, which are primarily detoxified via glutathione conjugation. In this study, it was hypothesized that molecules involved in the synthesis of glutathione would be diminished to replenish the glutathione depleted through conjugation reactions. Since S-adenosylmethionine (SAMe) is the primary source of the sulfur atom in glutathione, UPLC/MS and NMR were used to evaluate metabolites involved with the transulfuration pathway in urine samples collected during studies of eight liver toxic compounds in Sprague-Dawley rats. Urinary levels of creatine were increased on day 1 or day 2 in 8 high dose liver toxicity studies. Taurine concentration in urine was increased in only 3 of 8 liver toxicity studies while SAMe was found to be reduced in 4 of 5 liver toxicity studies. To further validate the results from the metabonomic studies, microarray data from rat liver samples following treatment with acetaminophen was obtained from the Gene Expression Omnibus (GEO) database. Some genes involved in the trans-sulfuration pathway, including guanidinoacetate N-methyltransferase, glycine N-methyltransferase, betaine-homocysteine methyltransferase and cysteine dioxygenase were found to be significantly decreased while methionine adenosyl transferase II, alpha increased at 24 h post-dosing, which is consistent with the SAMe and creatine findings. The metabolic and transcriptomic results show that the trans-sulfuration pathway from SAMe to glutathione was disturbed due to the administration of heptatotoxicants

  12. Pulmonary Metastasis from Pseudomyxoma Peritonei

    Full Text Available Pseudomyxoma peritonei (PMP is a rare clinical condition, where copious mucinous ascites accumulate in the peritoneal cavity due to dissemination of mucin-producing tumor. Because of this disseminating, yet nonmetastasizing, behavior, PMP attracts much interest from surgical oncologists in that aggressive locoregional therapy can give the opportunity of long survival and even cure. Although extra-abdominal metastasis is exceptionally rare, the lung is the most likely site in such a case. In this paper, the clinical findings and treatment of eleven cases with pulmonary metastasis from PMP were reviewed, including ten cases in the literature and one case which we experienced. The clinical features of PMP cases with pulmonary metastasis were similar to cases without pulmonary metastasis. The histological type was low-grade mucinous neoplasm in most cases. Pulmonary lesions were resected in seven cases in which abdominal lesions were controlled by cytoreductive surgery and hyperthermic intraperitoneal chemotherapy or another therapeutic modality. Disease-free state was maintained in five cases at the end of the follow-up period. However, it should be noted that rapid progression after resection was seen in two cases, suggesting that biological features may have changed by surgical intervention.

    PurposePatients with breast cancer liver metastasis have a poor prognosis. Local therapy for liver metastasis increases survival. The purpose of this pilot prospective study was to evaluate the efficacy and safety of doxorubicin drug-eluting beads chemoembolization for liver-dominant breast cancer metastasis (LdBM) refractory to chemotherapy.Materials and MethodsAll patients with LdBM refractory to of two or more lines of systemic chemotherapy were screened. Two chemoembolizations at 1-month intervals were scheduled for each patient. Tumor responses were evaluated by MRI every 3 months until progression or death. Adverse events were recorded according to the Common Terminology Criteria for Adverse Events (CTCAE version 4.02) 1 month after each chemoembolization. All patients were free from systemic treatment until progression. Patients with hormone-positive receptors and/or HER-positive disease status continued their targeted therapy.ResultsOut of 23 patients enrolled (mean age: 57.5 ± 11.5 years), 17 completed two chemoembolizations and six underwent only one because of severe adverse events. At 3-month follow-up, the disease control rate was 83 %. The median progression-free survival from the first chemoembolization was 8 months, and the median overall survival was 17 months. Nineteen patients remained free from any systemic chemotherapy for a mean of 209 ± 92 days until progression. Eight grade 3 (asthenia n = 3, anemia n = 2, thrombocythemia n = 2, liver toxicity n = 1) (Rev 1 Comment 1) occurred after the first procedure. No patient died directly due to the procedure.ConclusionWhile chemoembolization with doxorubicin eluding beads for refractory LdBM leads to an 83 % disease control rate, it also causes severe side effects that need to be adequately managed.

    Full Text Available Ectopic breast tissue has the ability to undergo all the pathological changes of the normal breast, including breast cancer. Gastrointestinal metastasis of breast cancer is rarely observed and it is very difficult to differentiate gastric metastases from primary gastric cancer. We present a case of 52-year-old female, who suffered from abdominal pain. Physical examination showed a palpable mass in the left anterior axilla and computerized tomography revealed gastric wall thickening with linitis plastica. When gastroscopic biopsy showed no signs of malignancy, excisional biopsy was performed in the left axilla. Histological examination revealed invasive lobular carcinoma of the breast, consistent with ectopic breast cancer. Further gastroscopic submucosal biopsies and immunohistochemical studies revealed gastric metastases of invasive lobular carcinoma. Axillary ectopic breast tissue carcinomas can mimic axillary lymphadenopathies. Additionally, gastric metastasis of breast cancer is an uncommon but possible condition. To the best of our knowledge, this is the first report of ectopic breast cancer with gastric metastasis.

    There is growing interest in the quality of health care delivery in liver transplantation. Multiple stakeholders, including patients, transplant providers and their hospitals, payers, and regulatory bodies have an interest in measuring and monitoring quality in the liver transplant process, and understanding differences in quality across centres. This article aims to provide an overview of quality measurement and regulatory issues in liver transplantation performed within the United States. We review how broader definitions of health care quality should be applied to liver transplant care models. We outline the status quo including the current regulatory agencies, public reporting mechanisms, and requirements around quality assurance and performance improvement (QAPI) activities. Additionally, we further discuss unintended consequences and opportunities for growth in quality measurement. Quality measurement and the integration of quality improvement strategies into liver transplant programmes hold significant promise, but multiple challenges to successful implementation must be addressed to optimise value.

  16. Natural history of malignant bone disease in hepatocellular carcinoma: final results of a multicenter bone metastasis survey.

    Directory of Open Access Journals (Sweden)

    Daniele Santini

    Full Text Available BACKGROUND: Bone is an uncommon site of metastasis in patients with advanced hepatocellular carcinoma (HCC. Therefore, there are few studies concerning the natural history of bone metastasis in patients with HCC. PATIENTS AND METHODS: Data on clinicopathology, survival, skeletal-related events (SREs, and bone-directed therapies for 211 deceased HCC patients with evidence of bone metastasis were statistically analyzed. RESULTS: The median age was 70 years; 172 patients were male (81.5%. The median overall survival was 19 months. The median time to the onset of bone metastasis was 13 months (22.2% at HCC diagnosis; 64.9% patients had multiple bone metastases. Spine was the most common site of bone metastasis (59.7%. Most of these lesions were osteolytic (82.4%; 88.5% of them were treated with zoledronic acid. At multivariate analysis, only the Child Score was significantly correlated with a shorter time to diagnosis of bone metastases (p = 0.001, HR = 1.819. The median survival from bone metastasis was 7 months. At multivariate analysis, HCC etiology (p = 0.005, ECOG performance status (p = 0.002 and treatment with bisphosphonate (p = 0.024 were associated with shorter survival after bone disease occurrence. The site of bone metastasis but not the number of bone lesions was associated with the survival from first skeletal related event (SRE (p = 0.021 and OS (p = 0.001. CONCLUSIONS: This study provides a significant improvement in the understanding the natural history of skeletal disease in HCC patients. An early and appropriate management of these patients is dramatically needed in order to avoid subsequent worsening of their quality of life.

    Full Text Available Abstract Background Advanced gastrointestinal stromal tumors (GISTs can metastasize and recur after a long remission period, resulting in serious morbidity, mortality, and complex management issues. Case presentation A 67-year-old woman presented with epigastric fullness, mild jaundice and weight loss with a history of a bowel resection 7 years prior for a primary GIST of the small bowel. The finding of a heterogeneous mass 15.5 cm in diameter replacing most of the left lobe of the liver by ultrasonography and CT, followed by positive cytological studies revealed a metastatic GIST. Perioperative optimization of the patient's nutritional status along with biliary drainage, and portal vein embolization were performed. Imatinib was successful in reducing the tumor size and facilitating surgical resection. Conclusion A well-planned multidisciplinary approach should be part of the standard management of advanced or metastatic GIST.

    An isolated splenic metastasis is a rare phenomenon noted in advanced stage melanoma. We report the role of radiofrequency (RF) -based splenic-preserving splenectomy in a patient with a solitary splenic metastasis from advanced stage melanoma that was managed with checkpoint inhibitors. We report a case of a 60-year-old man who presented with multiple lung metastases and a solitary splenic metastasis with advanced stage melanoma following excision of primary from his trunk 2.3 years back. Considering the diagnosis of advanced stage melanoma with multiple lung metastases and a solitary splenic metastasis, and its ongoing progressive nature. This case was discussed in the tumour board meeting. A decision was made to commence treatment with immunotherapy in the form of PD-1 inhibitor (programmed cell death 1 receptor) pembrolizumab. Follow-up restaging computer tomography (CT) scan of the abdomen and chest showed a significant reduction in the lung and chest wall lesions, but the splenic lesion remained unchanged. Given the lack of response to treatment in the splenic metastasis and the significant decrease in lung metastases, the multidisciplinary team decided that a partial splenectomy combined with continued immunotherapy treatment would be appropriate as the success of immunotherapy was imminent within the splenic preservation. The postoperative recovery was smooth and the patient was discharged from hospital on the sixth postoperative day with normal platelets and white blood cells. The histopathological analysis of the resected specimen showed a metastatic melanoma with negative margins.At 10-month follow-up after the splenic resection the patient had not experienced further tumour recurrences. Spleen-preserving resection for an isolated, solitary splenic metastasis of melanoma is a feasible approach as it not only preserves the ongoing efficacy of checkpoint inhibitors by preserving the physiological T cell milieu, but the immunomodulation properties of RF can

    Liver fibrosis reflects sustained liver injury often from multiple, simultaneous factors. Whilst the presence of mild fibrosis on biopsy can be a reassuring finding, the identification of advanced fibrosis is critical to the management of patients with chronic liver disease. This necessity has lead to a reliance on liver biopsy which itself is an imperfect test and poorly accepted by patients. The development of robust tools to non-invasively assess liver fibrosis has dramatically enhanced clinical decision making in patients with chronic liver disease, allowing a rapid and informed judgment of disease stage and prognosis. Should a liver biopsy be required, the appropriateness is clearer and the diagnostic yield is greater with the use of these adjuncts. While a number of non-invasive liver fibrosis markers are now used in routine practice, a steady stream of innovative approaches exists. With improvement in the reliability, reproducibility and feasibility of these markers, their potential role in disease management is increasing. Moreover, their adoption into clinical trials as outcome measures reflects their validity and dynamic nature. This review will summarize and appraise the current and novel non-invasive markers of liver fibrosis, both blood and imaging based, and look at their prospective application in everyday clinical care.

    The biological behavior and hence the prognosis of thyroid cancer (TC) depends among other factors on the extent of spread of the disease outside the thyroid bed. This effect is controversial, especially for nodal metastasis of well differentiated thyroid carcinoma (WDC). Nodal metastasis at the time of initial diagnosis behaves differently depending on the histology, age of the patient, presence of extrathyroidal extension, and the sex of the individual. The type of the surgery, administration of 131 I and thyroxin suppression also to some extent influence the rate of recurrence and mortality. Experience has shown that it is not as innocuous as a small intrathyroidal tumor without any invasion outside the thyroid bed and due consideration should be accorded to the management strategies for handling patients with nodal metastasis

    Metastasis is a key factor that affects the survival and prognosis of colorectal cancer patients. To elucidate molecular mechanism associated with the metastasis of colorectal cancer, genes related to the metastasis time of colorectal cancer were screened. Then, a network was constructed with this genes. Data was obtained from colorectal cancer expression profile. Molecular mechanism elucidated the time of tumor metastasis and the expression of genes related to colorectal cancer. We found that metastasis-promoting and metastasis-inhibiting networks included protein hubs of high connectivity. These protein hubs were components of organelles. Some ribosomal proteins promoted the metastasis of colorectal cancer. In some components of organelles, such as proteasomes, mitochondrial ribosome, ATP synthase, and splicing factors, the metastasis of colorectal cancer was inhibited by some sections of these organelles. After performing survival analysis of proteins in organelles, joint survival curve of proteins was constructed in ribosomal network. This joint survival curve showed metastasis was promoted in patients with colorectal cancer (P = 0.0022939). Joint survival curve of proteins was plotted against proteasomes (P = 7 e-07), mitochondrial ribosome (P = 0.0001157), ATP synthase (P = 0.0001936), and splicing factors (P = 1.35e-05). These curves indicate that metastasis of colorectal cancer can be inhibited. After analyzing proteins that bind with organelle components, we also found that some proteins were associated with the time of colorectal cancer metastasis. Hence, different cellular components play different roles in the metastasis of colorectal cancer. Copyright © 2018 Elsevier Inc. All rights reserved.

    Full Text Available Liver metastases from neuroendocrine tumours frequently occur and significantly worsen their prognosis. Somatostatin receptor scintigraphy (SRS is a valuable method for the detection of somatostatin receptor-positive lesions like gastrinoma. In this case report, the importance of SRS to localize the primary tumor and the spread of disease is emphasized in a patient with neuroendocrine liver metastases. A 45-year-old man was admitted to hospital with multiple liver metastasis of neuroendocrine carcinoma. Somatostatin receptor scintigraphy showed multiple intense radiotracer uptakes in the liver and a focal tracer uptake at the right side of the upper abdominal region corresponding to duodenum or pancreas. Elevated serum gastrin levels confirmed the gastrinoma diagnosis. (MRT 2011;20:117-120

    Brain metastasis (BM) is common in patients with breast cancer. Predicting patient survival is critical for the clinical management of breast cancer brain metastasis (BCBM). The present study was designed to develop and evaluate a prognostic model for patients with newly diagnosed BCBM. Based on the clinical data of patients with BCBM treated in the Affiliated Hospital of Academy of Military Medical Sciences (Beijing, China) between 2002 and 2014, a nomogram was developed to predict survival using proportional hazards regression analysis. The model was validated internally by bootstrapping, and the concordance index (c-index) was calculated. A calibration curve and c-index were used to evaluate discriminatory and predictive ability, in order to compare the nomogram with widely used models, including recursive partitioning analysis (RPA), graded prognostic assessment (GPA) and breast-graded prognostic assessment (Breast-GPA). A total of 411 patients with BCBM were included in the development of this predictive model. The median overall survival time was 14.1 months. Statistically significant predictors for patient survival included biological subtype, Karnofsky performance score, leptomeningeal metastasis, extracranial metastasis, the number of brain metastases and disease-free survival. A nomogram for predicting 1- and 2-year overall survival rates was constructed, which exhibited good accuracy in predicting overall survival with a concordance index of 0.735. This model outperformed RPA, GPA and Breast-GPA, based on the comparisons of the c-indexes. The nomogram constructed based on a multiple factor analysis was able to more accurately predict the individual survival probability of patients with BCBM, compared with existing models.

  5. Platelet "first responders" in wound response, cancer, and metastasis.

    Platelets serve as "first responders" during normal wounding and homeostasis. Arising from bone marrow stem cell lineage megakaryocytes, anucleate platelets can influence inflammation and immune regulation. Biophysically, platelets are optimized due to size and discoid morphology to distribute near vessel walls, monitor vascular integrity, and initiate quick responses to vascular lesions. Adhesion receptors linked to a highly reactive filopodia-generating cytoskeleton maximizes their vascular surface contact allowing rapid response capabilities. Functionally, platelets normally initiate rapid clotting, vasoconstriction, inflammation, and wound biology that leads to sterilization, tissue repair, and resolution. Platelets also are among the first to sense, phagocytize, decorate, or react to pathogens in the circulation. These platelet first responder properties are commandeered during chronic inflammation, cancer progression, and metastasis. Leaky or inflammatory reaction blood vessel genesis during carcinogenesis provides opportunities for platelet invasion into tumors. Cancer is thought of as a non-healing or chronic wound that can be actively aided by platelet mitogenic properties to stimulate tumor growth. This growth ultimately outstrips circulatory support leads to angiogenesis and intravasation of tumor cells into the blood stream. Circulating tumor cells reengage additional platelets, which facilitates tumor cell adhesion, arrest and extravasation, and metastasis. This process, along with the hypercoagulable states associated with malignancy, is amplified by IL6 production in tumors that stimulate liver thrombopoietin production and elevates circulating platelet numbers by thrombopoiesis in the bone marrow. These complex interactions and the "first responder" role of platelets during diverse physiologic stresses provide a useful therapeutic target that deserves further exploration.

    The purpose of this study was to develop a nude mouse model of bone metastasis by performing intracardiac injection of breast cancer cells under ultrasonography guidance and we wanted to evaluate the development and the distribution of metastasis in vivo using micro-CT, MRI and bioluminescence imaging. Animal experiments were performed in 6-week-old female nude mice. The animals underwent left ventricular injection of 2x105 MDA-MB-231Bo-Luc cells. After injection of the tumor cells, serial bioluminescence imaging was performed for 7 weeks. The findings of micro-CT, MRI and the histology were correlated with the 'hot' lesions seen on the bioluminescence imaging. Metastasis was found in 62.3% of the animals. Two weeks after intracardiac injection, metastasis to the brain, spine and femur was detected with bioluminescence imaging with an increasing intensity by week 7. Micro-CT scan confirmed multiple osteolytic lesions at the femur, spine and skull. MRI and the histology were able to show metastasis in the brain and extraskeletal metastasis around the femur. The intracardiac injection of cancer cells under ultrasonography guidance is a safe and highly reproducible method to produce bone metastasis in nude mice. This bone metastasis nude mouse model will be useful to study the mechanism of bone metastasis and to validate new therapeutics

    Colorectal cancer (CRC) metastatic dissemination to the liver is one of the most life-threatening malignancies in humans and represents the leading cause of CRC-related mortality. Herein, we adopted a gene transfer strategy into mouse hematopoietic stem/progenitor cells to generate immune-competent mice in which TEMs-a subset of Tie2(+) monocytes/macrophages found at peritumoral sites-express interferon-alpha (IFNα), a pleiotropic cytokine with anti-tumor effects. Utilizing this strategy in mouse models of CRC liver metastasis, we show that TEMs accumulate in the proximity of hepatic metastatic areas and that TEM-mediated delivery of IFNα inhibits tumor growth when administered prior to metastasis challenge as well as on established hepatic lesions, improving overall survival. Further analyses unveiled that local delivery of IFNα does not inhibit homing but limits the early phases of hepatic CRC cell expansion by acting on the radio-resistant hepatic microenvironment. TEM-mediated IFNα expression was not associated with systemic side effects, hematopoietic toxicity, or inability to respond to a virus challenge. Along with the notion that TEMs were detected in the proximity of CRC metastases in human livers, these results raise the possibility to employ similar gene/cell therapies as tumor site-specific drug-delivery strategies in patients with CRC. © 2016 The Authors.

Tumor cell invasion, metastasis and pathological angiogenesis are detected under fluorescent microscopy in the living fish. The average...

  11. Rewiring of an Epithelial Differentiation Factor, miR-203, to Inhibit Human Squamous Cell Carcinoma Metastasis

    Directory of Open Access Journals (Sweden)

    Nathan Benaich

    2014-10-01

    Full Text Available Summary: Metastatic colonization of distant organs underpins the majority of human-cancer-related deaths, including deaths from head and neck squamous cell carcinoma (HNSCC. We report that miR-203, a miRNA that triggers differentiation in multilayered epithelia, inhibits multiple postextravasation events during HNSCC lung metastasis. Inducible reactivation of miR-203 in already established lung metastases reduces the overall metastatic burden. Using an integrated approach, we reveal that miR-203 inhibits metastasis independently of its effects on differentiation.

    Regorafenib has been approved for treatment of patients with unresectable or recurrent gastrointestinal stromal tumors resistant to imatinib or sunitinib. However, regorafenib has severe side-effects, including acute liver failure. We describe the case of a patient with multiple liver metastases of a small intestinal stromal tumor who experienced acute liver failure while being treated with regorafenib. A 50-year-old patient with an unresectable small intestinal stromal tumor resistant to prior treatment with imatinib and sunitinib was started on regorafenib, but experienced acute liver failure 10 days later. Plasma exchange and steroid pulse treatment improved her liver function. During liver failure, abdominal ultrasonography showed to-and-fro flow in the portal vein. Lactate dehydrogenase concentration was markedly elevated to 1633 U/l. These findings indicate that liver failure in this patient was due to impaired liver blood flow. Regorafenib may impair liver blood flow, inducing acute liver failure. Copyright© 2015 International Institute of Anticancer Research (Dr. John G. Delinassios), All rights reserved.

    Purpose: To quantitatively assess the portal component of hepatic blood flow using computed tomography (CT) perfusion studies during superior mesenteric arterial portography. Material and Methods: Thirty-four patients with hepatocellular carcinoma and liver cirrhosis (LC) and 13 patients with liver metastasis without chronic liver disease were enrolled in this study. Ten milliliters of a non-ionic contrast medium (150 mgI) was injected at a rate of 5 ml/s via a catheter placed in the superior mesenteric artery. Single-slice cine CT images at the level of the main trunk or the right/left main trunk of the portal vein were acquired over 40 s. The deconvolution method was then used on these CT images to measure blood flow (BF), blood volume (BV), and mean transit time (MTT) in (a) liver parenchyma in patients with HCC and liver cirrhosis; (b) liver parenchyma in patients with liver metastasis without cirrhosis; (c) directly in the HCC; and (d) directly in one of the metastases. Results: In 34 LC patients (a), BF, BV, and MTT in the liver parenchyma were 44.7±24.5 ml/min/100 g, 3.9±2.4 ml/100 g, and 10.9±5.5 s, respectively. In 13 patients without cirrhosis (b), BF, BV, and MTT in the liver parenchyma were 89.6±52.0 ml/min/100 g, 6.3 ±3.2 ml/100 g, and 8.7±3.6 sec, respectively. A significant difference in BF and BV was seen in patients with liver cirrhosis compared to those without cirrhosis. BF, BV, and MTT measured directly in HCC (c) were 6.5±4.5 ml/min/100 g, 0.4±0.4 ml/100 g, and 3.0±3.1 sec respectively, and BF, BV, and MTT in liver metastases (d) were 19.3 ± 21.7 ml/min/100 g, 0.6±0.8 ml/100 g, and 1.8±1.6 s, respectively. Conclusion: CT perfusion studies during superior mesenteric arterial portography allow quantitative assessment of pure portal blood flow in the liver

    Primary liver cancer is a global disease that is on the increase. Hepatocellular carcinoma (HCC) accounts for most primary liver cancers and has a notably low survival rate, largely attributable to late diagnosis, resistance to treatment, tumour recurrence and metastasis. MicroRNAs (miRNAs/miRs) are regulatory RNAs that modulate protein synthesis. miRNAs are involved in several biological and pathological processes including the development and progression of HCC. Given the poor outcomes with current HCC treatments, miRNAs represent an important new target for therapeutic intervention. Several studies have demonstrated their role in HCC development and progression. While many risk factors underlie the development of HCC, one process commonly altered is iron homeostasis. Iron overload occurs in several liver diseases associated with the development of HCC including Hepatitis C infection and the importance of miRNAs in iron homeostasis and hepatic iron overload is well characterised. Aberrant miRNA expression in hepatic fibrosis and injury response have been reported, as have dysregulated miRNA expression patterns affecting cell cycle progression, evasion of apoptosis, invasion and metastasis. In 2009, miR-26a delivery was shown to prevent HCC progression, highlighting its therapeutic potential. Several studies have since investigated the clinical potential of other miRNAs with one drug, Miravirsen, currently in phase II clinical trials. miRNAs also have potential as biomarkers for the diagnosis of HCC and to evaluate treatment efficacy. Ongoing studies and clinical trials suggest miRNA-based treatments and diagnostic methods will have novel clinical applications for HCC in the coming years, yielding improved HCC survival rates and patient outcomes.

    Although obesity is known as a risk factor for several human cancers, the association of obesity with cancer recurrence and metastasis remains to be characterized. Here, B16-BL6 melanoma and Lewis lung carcinoma cells were intravenously injected into diabetic (db/db) and obese (ob/ob) mice. The number of experimental lung colonies was markedly promoted in these mice when compared with C57BL/6 mice. In contrast, tumor growth at the implanted site was comparable when cells were inoculated orthotopically. The use of B16-BL6 cells stably transfected with the luciferase gene revealed that the increased metastasis reflected a difference mainly within 6 hr after the intravenous inoculation of tumor cells. Administration of recombinant leptin in ob/ob mice abolished the increase in metastasis early on as well as the decrease in the splenic NK cell number. In addition, depletion of NK cells by an anti-asialo-GM1 antibody abrogated the enhanced metastasis in db/db mice. These results demonstrate that metastasis is markedly promoted in diabetic and obese mice mainly because of decreased NK cell function during the early phase of metastasis.

    To show that Wilson's disease is one likely cause of multiple low-intensity nodules of the liver we obtained MR images in 16 patients with clinically and histopathologically confirmed Wilson's disease. Corresponding to morphological changes MRI enabled the subdivision of the patients into two groups. Using a T 2 -weighted spin-echo sequence (TR/TE=2000/45-90) liver parenchyma showed multiple tiny low-intensity-nodules surrounded by high-intensity septa in 10 out of 16 patients. 5 patients had also low-intensity nodules in T 1 -weighted images (TR/TE=600/20). In patients of this group histopathology revealed liver cirrhosis (n=7) and fibrosis (n=2). Common feature of this patient group was marked inflammatory cell infiltration into fibrous septa, increase of copper concentration in liver parenchyma and distinct pathological changes of laboratory data. In the remaining 6 patients no pathological change of liver morphology was demonstrated by MRI corresponding to slight histopathological changes of parenchyma and normal laboratory data. As low-intensity nodules surrounded by high intensity septa can be demonstrated in patients with marked inflammatory infiltration of liver parenchyma MRI may help to define Wilson patients with poorer prognosis. In patients with low-intensity nodules of the liver and unknown cause of liver cirrhosis laboratory data and histopathology should be checked when searching for disorders of copper metabolism.

    Full Text Available Bone metastasis is a frequent occurrence in breast cancer, affecting more than 70% of late stage cancer patients with severe complications such as fracture, bone pain, and hypercalcemia. The pathogenesis of osteolytic bone metastasis depends on cross-communications between tumor cells and various stromal cells residing in the bone microenvironment. Several growth factor signaling pathways, secreted micro RNAs (miRNAs and exosomes are functional mediators of tumor-stromal interactions in bone metastasis. We developed a functional genomic approach to systemically identified molecular pathways utilized by breast cancer cells to engage the bone stroma in order to generate osteolytic bone metastasis. We showed that elevated expression of vascular cell adhesion molecule 1 (VCAM1 in disseminated breast tumor cells mediates the recruitment of pre-osteoclasts and promotes their differentiation to mature osteoclasts during the bone metastasis formation. Transforming growth factor β (TGF-β is released from bone matrix upon bone destruction, and signals to breast cancer to further enhance their malignancy in developing bone metastasis. We furthered identified Jagged1 as a TGF-β target genes in tumor cells that engaged bone stromal cells through the activation of Notch signaling to provide a positive feedback to promote tumor growth and to activate osteoclast differentiation. Substantially change in miRNA expression was observed in osteoclasts during their differentiation and maturation, which can be exploited as circulating biomarkers of emerging bone metastasis and therapeutic targets for the treatment of bone metastasis. Further research in this direction may lead to improved diagnosis and treatment strategies for bone metastasis.

  18. Role of Tumor-Derived Chemokines in Osteolytic Bone Metastasis

    Full Text Available Metastasis is the primary cause of mortality and morbidity in cancer patients. The bone marrow is a common destination for many malignant cancers, including breast carcinoma (BC, prostate carcinoma, multiple myeloma, lung carcinoma, uterine cancer, thyroid cancer, bladder cancer, and neuroblastoma. The molecular mechanism by which metastatic cancer are able to recognize, infiltrate, and colonize bone are still unclear. Chemokines are small soluble proteins which under normal physiological conditions mediate chemotactic trafficking of leukocytes to specific tissues in the body. In the context of metastasis, the best characterized role for the chemokine system is in the regulation of primary tumor growth, survival, invasion, and homing to specific secondary sites. However, there is ample evidence that metastatic tumors exploit chemokines to modulate the metastatic niche within bone which ultimately results in osteolytic bone disease. In this review, we examine the role of chemokines in metastatic tumor growth within bone. In particular, the chemokines CCL2, CCL3, IL-8/CXCL8, and CXCL12 are consistently involved in promoting osteoclastogenesis and tumor growth. We will also evaluate the suitability of chemokines as targets for chemotherapy with the use of neutralizing antibodies and chemokine receptor-specific antagonists.

    2012-01-01

    Full Text Available Brain metastases arise in 10%–40% of all cancer patients. Up to one third of the patients do not have previous cancer history. We report a case of a 67-years-old male patient who presented with confusion, tremor, and apraxia. A brain MRI revealed an isolated right temporal lobe lesion. A thorax-abdomen-pelvis CT scan showed no primary lesion. The patient underwent a craniotomy with gross-total resection. Histopathology revealed an intestinal-type adenocarcinoma. A colonoscopy found no primary lesion, but a PET-CT scan showed elevated FDG uptake in the appendiceal nodule. A right hemicolectomy was performed, and the specimen showed a moderately differentiated mucinous appendiceal adenocarcinoma. Whole brain radiotherapy was administrated. A subsequent thorax-abdomen CT scan revealed multiple lung and hepatic metastasis. Seven months later, the patient died of disease progression. In cases of undiagnosed primary lesions, patients present in better general condition, but overall survival does not change. Eventual identification of the primary tumor does not affect survival. PET/CT might be a helpful tool in detecting lesions of the appendiceal region. To the best of our knowledge, such a case was never reported in the literature, and an appendiceal malignancy should be suspected in patients with brain metastasis from an undiagnosed primary tumor.

    Intraocular metastasis is the most common malignancy of the eye. The frequency of intraocular metastasis in all the patients dying of cancer is about 12% and ocular metastases will be detected more frequently in the future because the patients with malignant tumor are now living longer. Intraocular metastasis can cause a serious clinical problem such as blindness. The early recognition and treatment of intraocular metastasis are very important clinical oncologic issues to maintain vision and to maximize the quality of life. However, significance of intraocular metastasis is still under-evaluated for practicing oncologists. External beam radiotherapy is a safe, effective palliative treatment in terms of preserving both the vision and the eye globe.

    Full text: Osteosarcoma is considered the most common malignant primary bone tumour in children and adolescents. The lungs are the common sites of metastasis, which, if present, are associated with poor prognosis. Imaging workup includes x-ray, computed tomography, nuclear resonance imaging and bone scintigraphy in order to diagnose, help to choose appropriate treatment and prognosticate this disease. Chemotherapy is used to increase survival rate and to control the occurrence of lung metastasis. CASE 1: ELWS, male, 6 years old. The patient had a left knee trauma followed by increase in size and pain over 15 days. Knee x-ray showed a voluminous lesion and densely calcified tissue in the left knee, with soft tissue involvement. Chest x-ray showed multiple nodular dense lesions diffusely involving the lungs. Left knee MRI showed a neoplasm involving the distal epiphysis of the femur with extension from the bone marrow to the trochanteric region. Biopsy diagnosed small cell osteosarcoma. Chest computed tomography showed multiple opacities in the parenchyma of both lungs, most with calcification, predominantly in the cortical region. Bone scintigraphy showed intense uptake of the radiopharmaceutical in the distal half of the left femur and focal areas of increased uptake in the skull, left humerus, right scapula, thoracic soft tissue (mostly in the right side, in the same place as the pulmonary metastasis seen in the chest computed tomography), 12th thoracic vertebra, 4th lumbar vertebra and in the pelvis. CASE 2: ACD, male 20 years old. The patient presented pain and increase in size of the right knee starting 5 months ago. Right knee x-ray: insufflating bony lesion in the proximal epiphysis of the right tibia compatible with osteosarcoma; increase in volume in soft tissue around the knee. Right knee MRI: voluminous expansive osteoblastic lesion hypointense in T1 and heterogeneous in T2, diffusely enhanced by the use of gadolinium-DTPA; the lesion involved almost

    Full Text Available A 63-year-old man visited the clinic with numbness in the right hand. Magnetic resonance imaging demonstrated multiple low-intensity lesions in the cervical vertebrae and sacrum, which was suspicious of cervical bone metastasis. Fluorodeoxyglucose positron emission tomography/computed tomography revealed areas of increased fluorodeoxyglucose uptake in the thoracic esophagus, sternum and sacrum. A flat, elevated esophageal cancer was identified by upper gastrointestinal endoscopy, and the macroscopic appearance indicated early-stage disease. From the cervical, thoracic and abdominal computed tomography images, there were no metastatic lesions except for the bone lesions. To confirm whether the bone lesions were metastatic, we performed bone biopsy. The histopathological diagnosis was bone marrow hyperplasia. It was crucial for treatment planning to establish whether the lesions were distant metastases. Here, we report a case of esophageal cancer with bone marrow hyperplasia mimicking bone metastasis.

    Radioembolization with {sup 90}Y-loaded microspheres is increasingly used in the treatment of primary and secondary liver cancer. Technetium-99 m macroaggregated albumin (MAA) scintigraphy is used as a surrogate of microsphere distribution to assess lung or digestive shunting prior to therapy, based on tumoral targeting and dosimetry. To date, this has been the sole pre-therapeutic tool available for such evaluation. Several dosimetric approaches have been described using both glass and resin microspheres in hepatocellular carcinoma (HCC) and liver metastasis. Given that each product offers different specific activities and numbers of spheres injected, their radiobiological properties are believed to lightly differ. This paper summarizes and discusses the available studies focused on MAA-based dosimetry, particularly concentrating on potential confounding factors like clinical context, tumor size, cirrhosis, previous or concomitant therapy, and product used. In terms of the impact of tumoral dose in HCC, the results were concordant and a response relationship and tumoral threshold dose was clearly identified, especially in studies using glass microspheres. Tumoral dose has also been found to influence survival. The concept of treatment intensification has recently been introduced, yet despite several studies publishing interesting findings on the tumor dose-metastasis relationship, no consensus has been reached, and further clarification is thus required. Nor has the maximal tolerated dose to the liver been well documented, requiring more accurate evaluation. Lung dose was well described, despite recently identified factors influencing its evaluation, requiring further assessment. MAA SPECT/CT dosimetry is accurate in HCC and can now be used in order to achieve a fully customized approach, including treatment intensification. Yet further studies are warranted for the metastasis setting and evaluating the maximal tolerated liver dose. (orig.)

    CXCR4 receptors have been implicated in tumorigenesis and proliferation, making it a potential target for colorectal cancer therapy. Expression of this chemokine receptor on cellular surfaces appears to promote metastasis by directly stimulating tumor cell migration and invasion. The receptor/ligand, CXCR4/SDF-1α, pair are critically important to angiogenesis and vascular remodeling which supports cancer proliferation. Our work has shown that a novel apoptotic peptide of HIV-1, Nef-M1, can act as a CXCR4 antagonist, inducing apoptosis in CXCR4 containing cells. Four colorectal tumor cell lines (HT-29, LS174t, SW480, WiDr), were evaluated for their response to Nef-M1 peptide via in vivo and in vitro. The presence of CXCR4 receptors on tumor cells was determined using immunohistochemical and RT-PCR analyses. Solid xenografts derived from tumor cell lines grown in SCID mice, were evaluated for the persistence of the receptor. Xenografts propagated in SCID mice from each of the four cell lines demonstrated high levels of receptor expression as well. The effects of Nef-M1 in vivo via splenic injected mice and subsequent hepatic metastasis also demonstrated dramatic reduction of primary tumor growth in the spleen and secondary invasion of the liver. We concluded that Nef-M1 peptide, through physical interaction(s) with CXCR4, drives apoptotic reduction in in vivo primary tumor growth and metastasis. PMID:20383296

    Cerebral metastasis occur in 20 to 30 percent of patients with systemic cancer and are the most common type of intracranial tumor. The median survival of untreated patients is one month with a slightly longer survival in those treated with steroids. Patients treated with whole brain radiation therapy survive between 3 to 6 months. In selected cases survival can increase to 10 to 12 months with combination of surgery and radiotherapy or stereotactic radiosurgery alone or associated to radiotherapy. Most brain metastasis arise from lung, breast and melanomas. The most important criteria for selecting patients who will benefit from surgery or stereotactic radiosurgery are a Karnofsky score of 70 or more, systemic control of the cancer and absence of leptomeningeal involvement. Surgery is indicated in patients with a single lesion located in an accessible zone and stereotactic radiosurgery is indicated for lesions up to 3 cm of diameter, and in patients with up to 3 or 4 metastasis, no matter their location. The survival benefit of chemotherapy in brain metastasis has not been demonstrated

    Medical image segmentation plays an important role in digital medical research, and therapy planning and delivery. However, the presence of noise and low contrast renders automatic liver segmentation an extremely challenging task. In this study, we focus on a variational approach to liver segmentation in computed tomography scan volumes in a semiautomatic and slice-by-slice manner. In this method, one slice is selected and its connected component liver region is determined manually to initialize the subsequent automatic segmentation process. From this guiding slice, we execute the proposed method downward to the last one and upward to the first one, respectively. A segmentation energy function is proposed by combining the statistical shape prior, global Gaussian intensity analysis, and enforced local statistical feature under the level set framework. During segmentation, the shape of the liver shape is estimated by minimization of this function. The improved Chan-Vese model is used to refine the shape to capture the long and narrow regions of the liver. The proposed method was verified on two independent public databases, the 3D-IRCADb and the SLIVER07. Among all the tested methods, our method yielded the best volumetric overlap error (VOE) of 6.5 +/- 2.8 % , the best root mean square symmetric surface distance (RMSD) of 2.1 +/- 0.8 mm, the best maximum symmetric surface distance (MSD) of 18.9 +/- 8.3 mm in 3D-IRCADb dataset, and the best average symmetric surface distance (ASD) of 0.8 +/- 0.5 mm, the best RMSD of 1.5 +/- 1.1 mm in SLIVER07 dataset, respectively. The results of the quantitative comparison show that the proposed liver segmentation method achieves competitive segmentation performance with state-of-the-art techniques.

    Full Text Available Management of unresectable urothelial cancer (UC has been a clinical challenge for decades. While drug resistance is a key issue, precise understanding of biology of UC metastasis is another challenge for the improvement of treatment outcome of UC patients. Introduction of the cell biology concepts including epithelial-mesenchymal transition (EMT and cancer stemness seems to explain UC metastasis. Molecular genetics based on gene expression profiling, next generation sequencing, and explosion of non-coding RNA world has opened the door to intrinsic molecular subtyping of UC. Next steps include, based on the recently accumulated understanding, the establishment of novel disease models representing UC metastasis in various experimental platforms, particularly in vivo animal systems. Indeed, novel knowledge molecular genetics has not been fully linked to the modeling of UC metastasis. Further understanding of bladder carcinogenesis is needed particularly with regard to cell of origin related to tumor characteristics including driver gene alterations, pathological differentiations, and metastatic ability. Then we will be able to establish better disease models, which will consequently lead us to further understanding of biology and eventually the development of novel therapeutic strategies for UC metastasis.

    Metastasis accounts for most cancer-related deaths. The majority of solid cancers, including those of the breast, colorectum, prostate and skin, metastasize at significant levels to the liver due to its hemodynamic as well as tumor permissive microenvironmental properties. As this occurs prior to detection and treatment of the primary tumor, we need to target liver metastases to improve patients' outcomes. Animal models, while proven to be useful in mechanistic studies, do not represent the heterogeneity of human population especially in drug metabolism lack proper human cell-cell interactions, and this gap between animals and humans results in costly and inefficient drug discovery. This underscores the need to accurately model the human liver for disease studies and drug development. Further, the occurrence of liver metastases is influenced by the primary tumor type, sex and race; thus, modeling these specific settings will facilitate the development of personalized/targeted medicine for each specific group. We have adapted such all-human 3D ex vivo hepatic microphysiological system (MPS) (a.k.a. liver-on-a-chip) to investigate human micrometastases. This review focuses on the sources of liver resident cells, especially the iPS cell-derived hepatocytes, and examines some of the advantages and disadvantages of these sources. In addition, this review also examines other potential challenges and limitations in modeling human liver.

    Background A small remnant liver volume is an important risk factor for posthepatectomy liver failure and can be predicted accurately by computed tomography (CT) volumetry using radiologic image analysis software. Unfortunately, this software is expensive and usually requires support by a radiologist. ImageJ is a freely downloadable image analysis software package developed by the National Institute of Health (NIH) and brings liver volumetry to the surgeon’s desktop. We aimed to assess the accuracy of ImageJ for hepatic CT volumetry. Methods ImageJ was downloaded from http://www.rsb.info.nih.gov/ij/. Preoperative CT scans of 15 patients who underwent liver resection for colorectal cancer liver metastases were retrospectively analyzed. Scans were opened in ImageJ; and the liver, all metastases, and the intended parenchymal transection line were manually outlined on each slice. The area of each selected region, metastasis, resection specimen, and remnant liver was multiplied by the slice thickness to calculate volume. Volumes of virtual liver resection specimens measured with ImageJ were compared with specimen weights and calculated volumes obtained during pathology examination after resection. Results There was an excellent correlation between the volumes calculated with ImageJ and the actual measured weights of the resection specimens (r² = 0.98, p volumetry on a personal computer. This application brings CT volumetry to the surgeon’s desktop at no expense and is particularly useful in cases of tertiary referred patients, who already have a proper CT scan on CD-ROM from the referring institution. Most likely the discrepancy between volume and weight results from exsanguination of the liver after resection. PMID:17726630

    A 65-year-old woman underwent surgery for right breast cancer (TIN1aM0) in December 2005. In March 2011, the breast cancer recurred with multiple lung and lymph node metastases. In February 2013, because of multiple brain metastases whole-brain radiation therapy was performed. In January 2014, she developed paralysis of the left leg. Spinal cord magnetic resonance imaging revealed a mass lesion (Th12 to L1 level) in the spinal cord, and she was diagnosed with intramedullary spinal cord metastasis (ISCM) from the breast cancer. Spinal cord irradiation reduced the metastasis and improved her paralysis. Although pharmacotherapy was continued, her metastases, with the exception of ISCM, progressed and she died of the disease in November 2014. It is necessary to diagnose ISCM at the time of its onset. Additionally immediate therapeutic intervention can significantly reduce the volume of ISCM, resulting in symptomatic relief from neurological deficit; in this case, radiation therapy was effective.

    2018-05-22

    In recent years different therapeutic strategies for synchronously liver metastasized colorectal cancer were described. Apart from the classical staged surgical approach, simultaneous and liver-first strategies are now commonly used. One theoretical drawback of the classical approach is, however, the stimulatory effect on liver metastases growth that may result from resection of the primary tumour. This systematic review, therefore, aims to investigate the current insights on the stimulatory effects of colorectal surgery on the growth of synchronous colorectal liver metastases in humans. The systematic review was conducted according to the PRISMA statement. A literature search was performed using PubMed and Embase. Articles investigating the effects of colorectal surgery on synchronous colorectal liver metastases were included. Primary endpoints were metastatic tumor volume, metabolic and proliferative activity and tumour vascularization. Four articles meeting the selection criteria were found involving 200 patients. These studies investigate the effects of resection of the primary tumour on synchronous liver metastases using histological and radiological techniques. These papers support a possible stimulatory effect of resection of the primary tumor. Some limited evidence supports the hypothesis that colorectal surgery might stimulate the growth and development of synchronous colorectal liver metastases.

Complement component 1, q subcomponent binding protein (C1QBP) can mediate growth factor-induced cancer cell chemotaxis and distant metastasis by activation of receptor tyrosine kinases. Coincidentally, insulin-like growth factor-1 (IGF-1) derived from the liver and cancer cells itself has been recognized as a critical inducer of hepatic metastasis. However, the mechanism underlying IGF-1-dependent hepatic metastasis of pancreatic cancer, in which C1QBP may be involved, remains unknown. In the study, we demonstrated a significant association between C1QBP expression and hepatic metastasis in patients with pancreatic cancer. IGF-1 induced the translocation of C1QBP from cytoplasm to lipid rafts and further drove the formation of CD44 variant 6 (CD44v6)/C1QBP complex in pancreatic cancer cells. C1QBP interacting with CD44v6 in lipid rafts promoted phosphorylation of IGF-1R and thus activated downstream PI3K and MAPK signaling pathways which mediated metastatic potential of pancreatic cancer cells including proliferation, apoptosis, invasion, adhesion and energy metabolism. Furthermore, C1QBP knockdown suppressed hepatic metastasis of pancreatic cancer cells in nude mice. We therefore conclude that C1QBP in lipid rafts serves a key regulator of IGF-1/IGF-1R-induced hepatic metastasis from pancreatic cancer. Our findings about C1QBP in lipid rafts provide a novel strategy to block IGF-1/IGF-1R signaling in pancreatic cancer and a reliable premise for more efficient combined modality therapies. © 2017 UICC.

    Primary cardiac tumors are extremely rare. By comparison, metastatic involvement of the heart is over 20 times more common and has been reported in autopsy series in up to one in five patients dying of cancer. Cardiac metastasis of chondrosarcoma is absolutely not frequent. In the recent literature, a cardiac metastasis from chondrosarcoma has never been described. We report the case of an 18-year-old man with a diagnosis of cardiac metastasis that originated from a left scapular chondrosarcoma. Chondrosarcoma is a skeletal tumor with various grades of malignancy, rapidly evolving, and with a strong tendency to metastasize, with low responsiveness to chemotherapy. The onset of characteristic systemic symptoms in the late stage of the disease led to the diagnosis of a mass localized in the right atrium. Management and differential diagnosis of infective heart lesions were also very complex in a rapidly evolving life-threatening condition.

    Peritoneal metastasis is frequent mode of dissemination of intraabdominal malignancies. Radiologic diagnosis of peritoneal metastasis has relied on indirect evidence on a barium UGI series and small bowel examination. With the advent of CT scanning, CT is capable of direct imaging of peritoneum. The sensitivity of CT in detecting peritoneal metastasis and CT manifestation of peritoneal metastatic lesions had reported occasionally, but rarely in Korea. So, authors illustrated the CT manifestation of peritoneal metastatic lesions in 32 cases of macroscopically proven cases in laparoscopy or laparotomy in Korea University Hae Wha Hospital during recent 4 years. The results are as follows. 1. Of total 32 cases, 18 cases were male and 14 cases were female. Age incidence was the most common in 6th decade. 2. The most common type of malignancy that cause peritoneal metastasis was the stomach cancer and next common type of malignancies were pancreas cancer in men and ovarian cancer in women. 3. Of total 32 cases of peritoneal metastasis which was confirmed by laparoscopy or laparotomy macroscopically, 23 cases (72%) were detected peritoneal thickening and/or omental pathology by CT, and the remaining 9 cases (28%) were not detected by CT. 4. Ascites was present in 19 cases (59%). 5. Parietal peritoneal thickening was present in 16 cases (50%) by CT and sheetlike pattern was the most common findings. The patterns of peritoneal thickening was relatively nonspecific and was not correlated with primary tumor type. 6. Tumor involvement of greater omentum by CT was present in 19 cases (59%). There were 7 cases of smudged appearance pattern, 6 cases of nodular pattern, 6 cases of omental cake pattern and no cystic mass pattern. The patterns of omental pathology was relatively nonspecific and was nor correlated with primary tumor type

    Agaricus blazei Murill extract (ABM) has been reported to possess antitumor effects. In this study, the role of ABM in tumor growth and metastasis in vivo was evaluated in experimental Smmu 7721 hepatoma cells in severe combined immunodeficiency (SCID) mice and B16F10 melanoma cells lung metastasis in C57BL/6 mice. For the tumor growth model, the size of the liver tumor mass was about 10 mm to 20 mm in the control group. In comparison with the control group, the tumor mass seem to grow slowly with ABM treatment, especially at the high dose. For the tumor metastasis model, after a six-week treatment, the survival rates of B6 mice were 0%, 30%, 10% and 50% for control group, low, median and high concentration ABM treatment groups, respectively. The survival rate showed that pretreatment of C57BL/6 (B6) mice with ABM lengthened their lifespan after tumor cell inoculation, which supports the notion that ABM successfully reduced lung metastasis formation by B16F10 melanoma cells. The treatment effect was dependent on the concentration of ABM for tumor growth and metastasis in these models.

    The growth of cancer metastases in the liver depends on a permissive interaction with the hepatic microenvironment and neutrophils can contribute to this interaction, either positively or negatively, depending on their phenotype. Here we investigated the role of IGF-I in the control of the tumor microenvironment in the liver, using mice with a conditional, liver-specific, IGF-I deficiency (iLID) induced by a single tamoxifen injection. In mice that had a sustained (3 weeks) IGF-I deficiency prior to the intrasplenic/portal inoculation of colon carcinoma MC-38 cells, we observed an increase in neutrophil accumulation in the liver relative to controls. However, unlike controls, these neutrophils did not acquire the (anti-inflammatory) tumor-promoting phenotype, as evidenced by retention of high ICAM-1 expression and nitric oxide production and low CXCR4, CCL5, and VEGF expression and arginase production, all characteristic of the (pro-inflammatory) phenotype. This coincided with an increase in apoptotic tumor cells and reduced metastasis. Neutrophils isolated from these mice also had reduced IGF-IR expression levels. These changes were not observed in iLID mice with a short-term (2 days) IGF-I depletion, despite a 70% reduction in their circulating IGF-I levels, indicating that a sustained IGF-I deficiency was necessary to alter the neutrophil phenotype. Similar results were obtained with the highly metastatic Lewis lung carcinoma subline H-59 cells and in mice injected with an IGF-Trap that blocks IGF-IR signaling by reducing ligand bioavailability. Our results implicate the IGF axis in neutrophil polarization and the induction of a pro-metastatic microenvironment in the liver.

    Liver tumor initiating cells (TICs) have self-renewal and differentiate capacities, and largely contribute to tumor initiation, metastasis and drug resistance. MAPK signaling is a critical pathway in many biological processes, while its role in liver TICs hasn't been explored. Online-available dataset was used for unbiased screening. Liver TICs were examined CD133 FACS or oncosphere formation. TIC self-renewal was detected by oncosphere formation and tumor initiation assay. LncRNA function was detected by loss of function or gain of function assays. The molecular mechanism of lncRNA was explored by RNA pulldown, RNA immunoprecipitation, ChIP, western blot and double FISH. Here, we examined the expression profiles of MAPK components (MAPKs, MAP2Ks, MAP3Ks, MAP4Ks), and found MAPK6 is most highly expressed in liver cancer samples. Moreover, a divergent lncRNA (long noncoding RNA) of MAPK6, termed lncMAPK6 here, is also overexpressed along with liver tumorigenesis. LncMAPK6 promotes liver tumor propagation and TIC self-renewal through MAPK6. LncMAPK6 interacts with and recruits RNA polymerase II to MAPK6 promoter, and finally activates the transcription of MAPK6. Through MAPK6 transcriptional regulation, lncMAPK6 drives MARK signaling activation. LncMAPK6-MAPK6 pathway can be used for liver TIC targeting. Altogether, lncMAPK6 promotes MARK signaling and the self-renewal of liver TICs through MAPK6 expression. MAPK6 was the most highly expressed MAPK component in liver cancer and liver TICs and lncMAPK6 participated in the transcriptional regulation of MAPK6in cis. This work revealed the importance role of MAPK signaling in liver TIC self-renewal and added a new layer for liver TIC and MAPK6 expression regulation.

    Hemorrhagic complications are the most common major complications that occur after radiofrequency ablation, but hematemesis as a complication after radiofrequency ablation for hepatic tumor has not been mentioned before. A hepatogastric fistula as a delayed complication is also rare. We present the case of a 77-year-old man with severe hematemesis that occurred 2 months after radiofrequency ablation of a liver metastasis of gastric cancer. A ruptured hepatic artery pseudoaneurysm and a hepatogastric fistula were confirmed through serial imaging examinations. The current case is reported in combination with 2 rare major complications after radiofrequency ablation of a liver tumor. Copyright © 2018. Published by Elsevier Inc.

    Full Text Available Previous studies have investigated that the expression levels of MALAT-1 were higher in cancerous tissues than matched histologically normal tissues. And, to some extent, overexpression of MALAT-1 was inclined to lymph node metastasis. This meta-analysis collected all relevant articles and explored the association between MALAT-1 expression levels and lymph node metastasis. We searched PubMed, EmBase, Web of Science, Cochrane Library, and OVID to address the level of MALAT-1 expression in cancer cases and noncancerous controls (accessed February 2015. And 8 studies comprising 696 multiple cancer patients were included to assess this association. The odds ratio (OR and its corresponding 95% confidence interval (CI were calculated to assess the strength of the association using Stata 12.0 version software. The results revealed there was a significant difference in the incidence of lymph node metastasis between high MALAT-1 expression group and low MALAT-1 expression group (OR = 1.94, 95% CI 1.15–3.28, P=0.013 random-effects model. Subgroup analysis indicated that MALAT-1 high expression had an unfavorable impact on lymph node metastasis in Chinese patients (OR = 1.87, 95% CI 1.01–2.46. This study demonstrated that the incidence of lymph node metastasis in patients detected with high MALAT-1 expression was higher than that in patients with low MALAT-1 expression in China.

    A 64-year-old man who underwent right hemicolectomy 3.5 years ago for ascending colon cancer and then RF ablation for two metastatic nodules in the liver was admitted to our hospital with a new metastatic nodule in the S6/7 segment of the liver. The CT scan showed a low attenuating metastatic nodule 2.2 cm in diameter in the S6/7 segment of the liver, and the liver showed peripheral bile duct dilatation. This nodule was treated with percutaneous RF ablation. A follow-up CT seven months after RF ablation showed the presence of a viable tumor in the RF ablation zone, with tumor extension along the dilated bile duct. These findings were confirmed on the resected specimen.

    The Empty Spiracles Homeobox (EMX-) 2 gene has been associated with regulation of growth and differentiation in neuronal development. While recent studies provide evidence that EMX2 regulates tumorigenesis of various solid tumors, its role in colorectal cancer remains unknown. We aimed to assess the prognostic significance of EMX2 expression in stage III colorectal adenocarcinoma. Expression levels of EMX2 in human colorectal cancer and adjacent mucosa were assessed by qRT-PCR technology, and results were correlated with clinical and survival data. siRNA-mediated knockdown and adenoviral delivery-mediated overexpression of EMX2 were performed in order to investigate its effects on the migration of colorectal cancer cells in vitro. Compared to corresponding healthy mucosa, colorectal tumor samples had decreased EMX2 expression levels. Furthermore, EMX2 down-regulation in colorectal cancer tissue was associated with distant metastasis (M1) and impaired overall patient survival. In vitro knockdown of EMX2 resulted in increased tumor cell migration. Conversely, overexpression of EMX2 led to an inhibition of tumor cell migration. EMX2 is frequently down-regulated in human colorectal cancer, and down-regulation of EMX2 is a prognostic marker for disease-free and overall survival. EMX2 might thus represent a promising therapeutic target in colorectal cancer.

    Gold markers implanted in or near a tumor can be used as x-ray visible landmarks for image based tumor localization. The aim of this study was to develop and demonstrate fast and reliable real-time segmentation of multiple liver tumor markers in intra-treatment kV and MV images and in cone-beam CT (CBCT) projections, for real-time motion management. Thirteen patients treated with conformal stereotactic body radiation therapy in three fractions had 2–3 cylindrical gold markers implanted in the liver prior to treatment. At each fraction, the projection images of a pre-treatment CBCT scan were used for automatic generation of a 3D marker model that consisted of the size, orientation, and estimated 3D trajectory of each marker during the CBCT scan. The 3D marker model was used for real-time template based segmentation in subsequent x-ray images by projecting each marker's 3D shape and likely 3D motion range onto the imager plane. The segmentation was performed in intra-treatment kV images (526 marker traces, 92 097 marker projections) and MV images (88 marker traces, 22 382 marker projections), and in post-treatment CBCT projections (42 CBCT scans, 71 381 marker projections). 227 kV marker traces with low mean contrast-to-noise ratio were excluded as markers were not visible due to MV scatter. Online segmentation times measured for a limited dataset were used for estimating real-time segmentation times for all images. The percentage of detected markers was 94.8% (kV), 96.1% (MV), and 98.6% (CBCT). For the detected markers, the real-time segmentation was erroneous in 0.2–0.31% of the cases. The mean segmentation time per marker was 5.6 ms [2.1–12 ms] (kV), 5.5 ms [1.6–13 ms] (MV), and 6.5 ms [1.8–15 ms] (CBCT). Fast and reliable real-time segmentation of multiple liver tumor markers in intra-treatment kV and MV images and in CBCT projections was demonstrated for a large dataset. (paper)

    Full Text Available Background & Aims: Circulating tumor DNA (ctDNA carrying tumor-specific sequence alterations has been found in the cell-free fraction of blood. Liver cancer tumor specimens are difficult to obtain, and noninvasive methods are required to assess cancer progression and characterize underlying genomic features. Methods: We analyzed 46 patients with hepatocellular carcinoma who underwent hepatectomy or liver transplantation and for whom whole-genome sequencing data was available. We designed personalized assays targeting somatic rearrangements of each tumor to quantify serum ctDNA. Exome sequencing was performed using cell-free DNA paired primary tumor tissue DNA from a patient with recurrent liver cancer after transcatheter arterial chemoembolization (TACE. Results: We successfully detected ctDNA from 100 μL of serum samples in 7 of the 46 patients before surgery, increasing with disease progression. The cumulative incidence of recurrence and extrahepatic metastasis in the ctDNA-positive group were statistically significantly worse than in the ctDNA-negative group (P = .0102 and .0386, respectively. Multivariate analysis identified ctDNA (OR 6.10; 95% CI, 1.11–33.33, P = .038 as an independent predictor of microscopic vascular invasion of the portal vein (VP. We identified 45 nonsynonymous somatic mutations in cell-free DNA after TACE and 71 nonsynonymous somatic mutations in primary tumor tissue by exome sequencing. We identified 25 common mutations in both samples, and 83% of mutations identified in the primary tumor could be detected in the cell-free DNA. Conclusions: The presence of ctDNA reflects tumor progression, and detection of ctDNA can predict VP and recurrence, especially extrahepatic metastasis within 2 years. Our study demonstrated the usefulness of ctDNA detection and sequencing analysis of cell-free DNA for personalized treatment of liver cancer.

    Full Text Available Adderall (dextroamphetamine/amphetamine is a widely prescribed medicine for the treatment of attention-deficit/hyperactivity disorder (ADHD and is considered safe with due precautions. Use of prescribed Adderall without intention to overdose as a cause of acute liver injury is extremely rare, and to our knowledge no cases have been reported in the English literature. Amphetamine is an ingredient of recreational drugs such as Ecstacy and is known to cause hepatotoxicity. We describe here the case of a 55-year-old woman who developed acute liver failure during the treatment of ADHD with Adderall. She presented to the emergency room with worsening abdominal pain, malaise, and jaundice requiring hospitalization. She had a past history of partial hepatic resection secondary to metastasis from colon cancer which was under remission at the time of presentation. She recovered after intensive monitoring and conservative management. Adderall should be used carefully in individuals with underlying liver conditions.

    Our previous work has demonstrated that extracellular ATP is an important pro-invasive factor, and in this study, we tapped into a possible mechanism involved. We discovered that ATP could upregulate both the intracellular expression and secretion of S100A4 in breast cancer cells and fibroblasts. Apart from stimulating breast cancer cell motility via intracellular S100A4, ATP enhanced the ability of breast cancer cells to transform fibroblasts into cancer-associated fibroblast (CAF)-like cells, which in turn secreted S100A4 to further promote cancer cell motility. Both apyrase and niclosamide treatments could inhibit metastasis of inoculated tumors to lung, liver and kidney in mice model, and CAFs from these treated tumors exhibited weakened migration-stimulating capacity for breast cancer cells. Collectively, our data indicate that extracellular ATP promotes the interactions between breast cancer cells and fibroblasts, which work collaboratively via production of S100A4 to exacerbate breast cancer metastasis.

    Tseng, Yu-Cheng

    A lipid/calcium/phosphate (LCP) nanoparticle formulation (particle diameter ˜25 nm) has previously been developed to delivery siRNA with superior efficiency. In this work, 111In was formulated into LCP nanoparticles to form 111In-LCP for SPECT/CT imaging. With necessary modifications and improvements of the LCP core-washing and surface-coating methods, 111In-LCP grafted with polyethylene glycol exhibited reduced uptake by the mononuclear phagocytic system. SPECT/CT imaging supported performed biodistribution studies, showing clear tumor images with accumulation of 8% or higher injected dose per gram tissue (ID/g) in subcutaneous, human-H460, lung-cancer xenograft and mouse-4T1, breast cancer metastasis models. Both the liver and the spleen accumulated ˜20% ID/g. Accumulation in the tumor was limited by the enhanced permeation and retention effect and was independent of the presence of a targeting ligand. A surprisingly high accumulation in the lymph nodes (˜70% ID/g) was observed. In the 4T1 lymph node metastasis model, the capability of intravenously injected 111In-LCP to visualize the size-enlarged and tumor-loaded sentinel lymph node was demonstrated. By analyzing the SPECT/CT images taken at different time points, the PK profiles of 111In-LCP in the blood and major organs were determined. The results indicated that the decrement of 111In-LCP blood concentration was not due to excretion, but to tissue penetration, leading to lymphatic accumulation. Larger LCP (diameter ˜65 nm) nanoparticles were also prepared for the purpose of comparison. Results indicated that larger LCP achieved slightly lower accumulation in the tumor and lymph nodes, but much higher accumulation in the liver and spleen; thus, larger nanoparticles might not be favorable for imaging purposes. We also demonstrated that LCP with a diameter of ˜25 nm were better able to penetrate into tissues, travel in the lymphatic system and preferentially accumulate in the lymph nodes due to 1) small

    The purpose of this study was to investigate the value of 18 F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) parameters in the detection of regional lymph node (LN) metastasis in patients with cutaneous melanoma. We evaluated patients with cutaneous melanoma who underwent FDG PET/CT for initial staging or recurrence evaluation. A total of 103 patients were enrolled, and 165 LNs were evaluated. LNs that were confirmed pathologically or by follow-up imaging were included in this study. PET parameters, including maximum standardized uptake value (SUVmax), total lesion glycolysis and tumour-to-liver ratio, were used to determine the presence of metastases, and the results were compared with CT-determined LN metastasis. Receiver operating characteristic (ROC) curve analysis was used to determine the optimal cut-off values of the FDG PET parameters. A total of 93 LNs were malignant, and 84 LNs were smaller than 10 mm. In all 165 LNs, an SUVmax of >2.51 showed a sensitivity of 73.1%, a specificity of 88.9%, and an accuracy of 80.0% in detecting metastatic LNs. CT showed a higher specificity (87.3%) and lower accuracy (65.5%). For non-enlarged regional LNs (2.4 showed a high sensitivity (91%) and accuracy (89%) in detecting metastasis in LNs ≥1 cm, and LNs <1 cm with an SUVmax <1.4 were likely to be benign.

    1989-01-01

    Twenty-seven cases of germ-cell tumors were examined with a CT scan in our clinic. In the 11 cases of metastasis or multi-localized tumors, the CT findings were studied in connection with the MRI findings. There were 6 cases of germ-cell tumors which had broad infiltrating tumors with multiple lesions on first admission. Their tumor sites were different from that in cases of malignant glioma, being frequently localized in the pineal and/or the suprasellar region, on the wall of the third and/or lateral ventricle, and in the region of the basal ganglia. Five of the cases of germ-cell tumors had metastasis with various patterns connected to a remote area - that is, to spinal cords, to the ventricular wall and basal cistern of the brain stem by CSF dissemination, to a lung by hematogeneous metastasis, and to the peritoneal wall or organs by a V-P shunt. The CT findings of germ-cell tumors were correlated mainly with the results of the histological diagnosis; they were found not to differ with the tumor site. The germinoma in the suprasellar region had less calcification than in the pineal region. Cysts, calcification, and an enlargement of the lateral ventricle on the tumor side were frequently seen in the germinoma of the basal ganglia. On the MRI of 5 cases of germinoma, the T 1 -weighted image revealed a slightly low or iso signal intensity, while the T 2 -weighted image showed a high signal intensity. In the case of multiple tumor lesions, some cases demonstrated different CT findings and radiosensitivities for each tumor. The possibility of a multicentric origin for the tumors is thus suggested in some cases of germ-cell tumors. (author)

    A 70-year-old woman was referred to our hospital because of abdominal pain. Abdominal computed tomography(CT)and colonoscopy revealed transverse colon cancer with multiple liver metastases, with involvement of the hepatic pedicle and superior mesenteric artery lymph nodes. The patient received eight courses of XELOX plus bevacizumab, and CT showed a decrease in the size of the liver metastases and hepatic pedicle lymphadenopathy. Right hemicolectomy, partial hepatectomy, and hepatic pedicle lymph node resection were performed. Histopathological examination of the resected tissue revealed no residual cancer cells, suggesting a pathological complete response. The patient remains well 7 months after operation, without any signs of recurrence. Surgical resection should be considered for patients with initially unresectable colon cancer with liver metastases and hepatic pedicle lymph nodes involvement if systemic chemotherapy is effective.

    Liver disease in human immunodeficiency virus (HIV)-infected individuals encompasses the spectrum from abnormal liver function tests, liver decompensation, with and without evidence of cirrhosis on biopsy, to non-alcoholic liver disease and its more severe form, non-alcoholic steatohepatitis and hepatocellular cancer. HIV can infect multiple cells in the liver, leading to enhanced intrahepatic apoptosis, activation and fibrosis. HIV can also alter gastro-intestinal tract permeability, leading to increased levels of circulating lipopolysaccharide that may have an impact on liver function. This review focuses on recent changes in the epidemiology, pathogenesis and clinical presentation of liver disease in HIV-infected patients, in the absence of co-infection with hepatitis B virus or hepatitis C virus, with a specific focus on issues relevant to low and middle income countries.

    Full Text Available A 76-year-old man was referred to our hospital with visual disturbance, weakness of the left upper and lower limbs, and gait disturbance. He had previously received transarterial chemoembolization for hepatocellular carcinoma (HCC 3 and 10 years ago. When he had received radiofrequency ablation for HCC recurrence 2 years ago, total gastrectomy was also performed for his gastric cancer. Subsequently, sorafenib had been administrated for concomitant lung metastatic tumors. On admission, MRI revealed an intra-axial tumor with perifocal edema. The level of carcinoembryonic antigen, but not alpha-fetoprotein, markedly increased. The tumor was successfully removed by craniotomy and pathological examination revealed that it was composed of adenocarcinoma, which was consistent with the primary gastric cancer. After surgery, his neurological disturbances rapidly resolved. Additional gamma-knife treatment was also performed for another small brain metastasis detected after craniotomy. Subsequently, sorafenib administration was discontinued and S-1 was administered postoperatively. Successful treatment of intracranial metastasis of gastric cancer is important and meaningful, even in patients with multiple primary malignancies.

    Full Text Available Skeletal muscle metastasis of nonsmall cell lung carcinoma (NSCLC is a rare occurrence, and the most effective treatment modality is currently unknown. In this case presentation, we report a patient with NSCLC who underwent palliative radiotherapy for biceps muscle metastasis of NSLCS. Our case was a 49-year-old woman who had lung adenocarcinoma with biceps muscle metastasis. She had been followed up for 2 years due to Stage IV lung adenocarcinoma from whom a biopsy was taken from a painful mass in right arm that was found to be compatible with metastasis of lung adenocarcinoma. She had palliative radiotherapy for her painful mass and systemic chemotherapy was planned. After palliative radiotherapy, the pain originating from the metastatic mass in right biceps muscle alleviated. Palliative radiotherapy can be a valuable treatment option for cases with skeletal muscle metastasis.

    To examine the association between liver histological features and organ-specific insulin resistance indices calculated from 75-g oral glucose tolerance test data in patients with non-alcoholic fatty liver disease. Liver biopsy specimens were obtained from 72 patients with non-alcoholic fatty liver disease, and were scored for steatosis, grade and stage. Hepatic and skeletal muscle insulin resistance indices (hepatic insulin resistance index and Matsuda index, respectively) were calculated from 75-g oral glucose tolerance test data, and metabolic clearance rate was measured using the euglycemic hyperinsulinemic clamp method. The degree of hepatic steatosis, and grade and stage of non-alcoholic steatohepatitis were significantly correlated with Matsuda index (steatosis r = -0.45, P hepatic insulin resistance index. Multiple regression analyses adjusted for age, sex, body mass index and each histological score showed that the degree of hepatic steatosis (coefficient = -0.22, P steatosis and metabolic clearance rate (coefficient = -0.62, P = 0.059). Liver steatosis is associated with insulin resistance in skeletal muscle rather than in the liver in patients with non-alcoholic fatty liver disease, suggesting a central role of fatty liver in the development of peripheral insulin resistance and the existence of a network between the liver and skeletal muscle.

    A 69 year old man who was diagnosed with renal transitional cell carcinoma (TCC) underwent F 18 fluorodeoxyglucose (FDG) positron emission tomography with computed tomography (PET/CT) for detecting recurrence after chemotherapy. FDG PET/CT revealed multiple new hypermetabolic lesions in many places, including the right thyroid gland. Biopsy of the thyroid lesion was performed,and a diagnosis of metastatic TCC was made. We could detect thyroid metastasis of renal TCC by FDG PET/CT.

  20. The role of lysyl oxidase, the extracellular matrix and the pre-metastatic niche in bone metastasis

    Full Text Available Most deaths from solid cancers occur as a result of secondary metastasis to distant sites. Bone is the most frequent metastatic site for many cancer types and can account for up to 80% of cancer-related deaths in certain tumours. The progression from a discrete solid primary tumour to devastating and painful bone metastases is a complex process involving multiple cell types and steps. There is increasing evidence that modulation of the extracellular matrix plays an important role in the lethal transition from a primary to disseminated metastatic bone tumour. This review provides an overview of the current understanding on the role of role of lysyl oxidase, the extracellular matrix and the pre-metastatic niche in bone metastasis

    2016-01-01

    Purpose: Radiosurgery of multiple (n>4) brain metastasis lesions requires 3–4 noncoplanar VMAT arcs with excessively high monitor units and long delivery time. We investigated whether an improved optimization technique would decrease the needed arc numbers and increase the delivery efficiency, while improving or maintaining the plan quality. Methods: The proposed 4pi arc space optimization algorithm consists of two steps: automatic couch angle selection followed by aperture generation for each arc with optimized control points distribution. We use a greedy algorithm to select the couch angles. Starting from a single coplanar arc plan we search through the candidate noncoplanar arcs to pick a single noncoplanar arc that will bring the best plan quality when added into the existing treatment plan. Each time, only one additional noncoplanar arc is considered making the calculation time tractable. This process repeats itself until desired number of arc is reached. The technique is first evaluated in coplanar arc delivery scheme with testing cases and then applied to noncoplanar treatments of a case with 12 brain metastasis lesions. Results: Clinically acceptable plans are created within minutes. For the coplanar testing cases the algorithm yields singlearc plans with better dose distributions than that of two-arc VMAT, simultaneously with a 12–17% reduction in the delivery time and a 14–21% reduction in MUs. For the treatment of 12 brain mets while Paddick conformity indexes of the two plans were comparable the SCG-optimization with 2 arcs (1 noncoplanar and 1 coplanar) significantly improved the conventional VMAT with 3 arcs (2 noncoplanar and 1 coplanar). Specifically V16 V10 and V5 of the brain were reduced by 11%, 11% and 12% respectively. The beam delivery time was shortened by approximately 30%. Conclusion: The proposed 4pi arc space optimization technique promises to significantly reduce the brain toxicity while greatly improving the treatment efficiency.

    Hypervascular adrenal masses include pheochromocytoma, metastases caused by clear renal cell carcinoma/hepatocellular carcinoma. Alveolar soft part sarcoma (ASPS) causing hypervascular metastases is not described in the literature. Here, we describe the first case of ASPS presenting as hypervascular metastasis. Our case was a 23-year-old male incidentally detected right adrenal mass during the evaluation of pain in the abdomen. On computed tomography (CT), adrenal mass showed bright enhancement in early arterial phase (unenhanced Hounsfield unit [HU]-45.3; arterial phase HU-158.2). 18- flurodeoxyglucose positron emission tomography/CT showed multiple lesions and was confirmed histologically to be due to ASPS.

  4. Harnessing high density lipoproteins to block transforming growth factor beta and to inhibit the growth of liver tumor metastases.

    Directory of Open Access Journals (Sweden)

    José Medina-Echeverz

    Full Text Available Transforming growth factor β (TGF-β is a powerful promoter of cancer progression and a key target for antitumor therapy. As cancer cells exhibit active cholesterol metabolism, high density lipoproteins (HDLs appear as an attractive delivery system for anticancer TGFβ-inhibitory molecules. We constructed a plasmid encoding a potent TGF-β-blocking peptide (P144 linked to apolipoprotein A-I (ApoA-I through a flexible linker (pApoLinkerP144. The ApoLinkerP144 sequence was then incorporated into a hepatotropic adeno-associated vector (AAVApoLinkerP144. The aim was to induce hepatocytes to produce HDLs containing a modified ApoA-I capable of blocking TGF-β. We observed that transduction of the murine liver with pApoLinkerP144 led to the appearance of a fraction of circulating HDL containing the fusion protein. These HDLs were able to attenuate TGF-β signaling in the liver and to enhance IL-12 -mediated IFN-γ production. Treatment of liver metastasis of MC38 colorectal cancer with AAVApoLinkerP144 resulted in a significant reduction of tumor growth and enhanced expression of IFN-γ and GM-CSF in cancerous tissue. ApoLinkerP144 also delayed MC38 liver metastasis in Rag2-/-IL2rγ-/- immunodeficient mice. This effect was associated with downregulation of TGF-β target genes essential for metastatic niche conditioning. Finally, in a subset of ret transgenic mice, a model of aggressive spontaneous metastatic melanoma, AAVApoLinkerP144 delayed tumor growth in association with increased CD8+ T cell numbers in regional lymph nodes. In conclusion, modification of HDLs to transport TGF-β-blocking molecules is a novel and promising approach to inhibit the growth of liver metastases by immunological and non-immunological mechanisms.

    To determine the most useful findings of gadoxetic acid-enhanced 3.0 Tesla (T) MRI for differentiating focal eosinophilic infiltration (FEI) from hepatic metastasis with verification of their usefulness. Pathologically or clinically proven 39 FEIs from 25 patients and 79 hepatic metastases from 51 patients were included in the study. Gadoxetic acid-enhanced 3.0T MRI was performed in all cancer patients. Size differences measured between T2-weighted and hepatobiliary-phase images for lesions > 1 cm and morphologic findings (margin, shape, signal intensity on T1- and T2-weighted images, enhancement pattern on dynamic images, and target appearance on hepatobiliary-phase images) were compared between two groups via Student's t test as well as univariate and multivariate analyses. Diagnostic predictive values of two observers for differentiating two groups were assessed before (session 1) and after (session 2) recognition of results. Mean size difference (2.1 mm) in FEIs between the two images was significantly greater than for metastases (0.7 mm) (p < 0.05). An ill-defined margin and isointensity on T1-weighted images were independently significant morphologic findings (p < 0.05) for differentiating the two groups. All observers achieved a higher diagnostic accuracy in session 2 (97% and 98%) than session 1 (92% and 89%) with statistical significance in observer 2 (p < 0.05). All observers had significantly higher sensitivities (95%) and negative predictive values (NPVs) (98%) in session 2 than in session 1 (sensitivity, 74% in two observers; NPV, 89% and 88%) (p < 0.05). With the size change, an ill-defined margin and isointensity on T1-weighted images are the most useful findings for differentiating FEI from hepatic metastasis on gadoxetic acid-enhanced 3.0T MRI.

    Objective: To analyze breast cancer bone metastasis related gene-CXCR4. Methods: This research screened breast cancer bone metastasis related genes by high-flux gene chip. Results:It was found that the expressions of 396 genes were different including 165 up-regulations and 231 down-regulations. The expression of chemokine receptor CXCR4 was obviously up-regulated in the tissue with breast cancer bone metastasis. Compared with the tissue without bone metastasis, there was significant difference, which indicated that CXCR4 played a vital role in breast cancer bone metastasis. Conclusions: The bioinformatics analysis of CXCR4 can provide a certain basis for the occurrence and diagnosis of breast cancer bone metastasis, target gene therapy and evaluation of prognosis.

  7. Adipokines and Non-Alcoholic Fatty Liver Disease: Multiple Interactions

    2017-07-01

    Full Text Available Accumulating evidence links obesity with low-grade inflammation which may originate from adipose tissue that secretes a plethora of pro- and anti-inflammatory cytokines termed adipokines. Adiponectin and leptin have evolved as crucial signals in many obesity-related pathologies including non-alcoholic fatty liver disease (NAFLD. Whereas adiponectin deficiency might be critically involved in the pro-inflammatory state associated with obesity and related disorders, overproduction of leptin, a rather pro-inflammatory mediator, is considered of equal relevance. An imbalanced adipokine profile in obesity consecutively contributes to metabolic inflammation in NAFLD, which is associated with a substantial risk for developing hepatocellular carcinoma (HCC also in the non-cirrhotic stage of disease. Both adiponectin and leptin have been related to liver tumorigenesis especially in preclinical models. This review covers recent advances in our understanding of some adipokines in NAFLD and associated HCC.

    The antimetastatic effect of BCG-CWS, which was emulsified in an oil-in-water form with either Drakeol 6VR mineral oil (BCG-CWS/DK) or squalane (BCG-CWS/SQA), on lung metastasis produced by highly metastatic murine tumor cells, Colon26-M3.1 carcinoma cells and B16-BL6 melanoma cells, was investigated in syngeneic mice. An intravenous (i.v.) administration of BCG-CWS (100 mg/mouse) 1 day after tumor inoculation significantly inhibited tumor metastasis of both Colon26-M3.1 carcinoma and B16-BL6 melanoma cells in experimental lung metastasis models. No differences in the antitumor activity of the two oil-based formulations (BCG-CWS/DK and BCG-CWS/SQA) were obverved. However, BCG-CWS/SQA administered through subcutaneous (s.c.) route was shown to be effective only when it was consecutively injected (3 times) after tumor inoculation. An in vivo analysis for tumor-induced angiogenesis showed that a single i.v. administration of BCG-CWS/SQA inhibited the number of tumor-induced blood vessels and suppressed tumor growth. Furthermore, the multiple administration of BCG-CWS/SQA given at on week intervals led to a significant reduction in spontaneous lung metastasis of B16-BL6 melanoma cells in a spontaneous metastasis model. These results suggest that BCG-CWS emulsified with squalane is a potent inhibitory agent of lung metastasis, and that the antimetastatic effect of BCG-CWS is related to the suppression of tumor growth and the inhibition of tumor-induced angiogenesis.

  9. Remodeling of the methylation landscape in breast cancer metastasis.

    Directory of Open Access Journals (Sweden)

    Marsha Reyngold

    Full Text Available The development of breast cancer metastasis is accompanied by dynamic transcriptome changes and dramatic alterations in nuclear and chromatin structure. The basis of these changes is incompletely understood. The DNA methylome of primary breast cancers contribute to transcriptomic heterogeneity and different metastatic behavior. Therefore we sought to characterize methylome remodeling during regional metastasis. We profiled the DNA methylome and transcriptome of 44 matched primary breast tumors and regional metastases. Striking subtype-specific patterns of metastasis-associated methylome remodeling were observed, which reflected the molecular heterogeneity of breast cancers. These divergent changes occurred primarily in CpG island (CGI-poor areas. Regions of methylome reorganization shared by the subtypes were also observed, and we were able to identify a metastasis-specific methylation signature that was present across the breast cancer subclasses. These alterations also occurred outside of CGIs and promoters, including sequences flanking CGIs and intergenic sequences. Integrated analysis of methylation and gene expression identified genes whose expression correlated with metastasis-specific methylation. Together, these findings significantly enhance our understanding of the epigenetic reorganization that occurs during regional breast cancer metastasis across the major breast cancer subtypes and reveal the nature of methylome remodeling during this process.

    Our aim was to investigate whether dynamic contrast-enhanced ultrasound (DCE-US) can detect early changes in perfusion of colorectal liver metastases after initiation of chemotherapy. Newly diagnosed patients with colorectal cancer with liver metastases were enrolled in this explorative prospective...... study. Patients were treated with capecitabine or 5-fluorouracil-based chemotherapy with or without bevacizumab. DCE-US was performed before therapy (baseline) and again 10 days after initiation of treatment. Change in contrast-enhancement in one liver metastasis (indicator lesion) was measured....... Treatment response was evaluated with a computed tomography (CT) scan after three cycles of treatment and the initially observed DCE-US change of the indicator lesion was related to the observed CT response. Eighteen patients were included. Six did not complete three series of chemotherapy...

    To analyze the detailed pattern of intraosseous failure after stereotactic body radiation therapy (SBRT) for coxal bone metastasis. Patients treated with SBRT to coxal bone metastasis were identified by retrospective chart review. The SBRT doses were 30 Gy or 35 Gy in 5 fractions. A margin of 5 to 10 mm was added to the gross tumor volume to create the clinical target volume. We evaluated the presence or absence of intraosseous recurrence using magnetic resonance imaging. Intraosseous recurrences were assessed as "in-field" or "marginal/out-of-field." In addition, we measured the distance between the center of the recurrent tumor and the nearest edge of the initial bone metastasis in cases of marginal/out-of-field recurrence. Seventeen patients treated for 17 coxal bone metastases were included. Median age was 64 years (range, 48-79 years). Coxal lesions involved the ilium in 14 cases, pubis in 3, and ischium in 4 (3 lesions crossed over multiple regions). Patients most commonly had renal cell carcinoma (29.4%), followed by lung, hepatic cell, and colorectal cancers (23.5%, 11.8%, and 11.8%, respectively). Median follow-up after SBRT was 13 months (range, 2-44 months). Among all 17 cases, 7 cases developed 8 intraosseous recurrences, including in-field recurrence in 1 case and marginal/out-of-field recurrences in 7 cases. Median time to intraosseous recurrence was 10 months (range, 2-35 months). Among 7 cases with marginal/out-of-field recurrence, mean distance to the center of the recurrent tumor from the nearest edge of the initial bone metastasis was 34 mm (range, 15-55 mm). Most recurrences were observed out-of-field in the same coxal bone. These results suggest that defining the optimal clinical target volume in SBRT for coxal bone metastasis to obtain sufficient local tumor control is difficult. Copyright © 2017 Elsevier Inc.

    2015-10-01

    We investigated the prognostic effect of lymph nodes metastasis in aortopulmonary (AP) zone in resected non-small cell lung cancer of the left upper lobe (LUL). Between 1998 and 2010, 181 patients with LUL carcinoma underwent complete resection and were retrospectively analyzed. The patients were divided into four groups according to N status: N0 (n = 68, 37.6%), N1 (n = 64, 35.3%), N2(5,6+) (only metastasized to stations 5 and/or 6, n = 36, 19.9%), and N2(7+) (only metastasized to stations 7, n = 13, 7.2%). N1 were divided according to single and multiple (N1(single) n = 49, N1(multiple) n = 15) or peripheral and hilar (N1(peripheral) n = 39, N1(hilar) n = 25). Overall 5-year survival rate was 55.1%. Five-year survivals were 76.1% for N0, 54.3% for N1, and 20.7% for N2. N1(peripheral) had a better survival than N1(hilar) (60.3 vs. 29.4%, p = 0.09). Five-year survival of N1(single) was 60.1%, whereas it was 36.6% for N1(multiple) (p = 0.02). Five-year survival rate was 24.6% for N2(5,6+). Skip metastasis for lymph nodes in AP zone (n = 13) was a factor of better prognosis as compared to nonskip metastasis (n = 23) (29.9 vs. 19.2%). There was no statistically significant difference between the N2(5,6+) and N1(hilar) (p = 0.772), although N1(peripheral) had a significantly better survival than N2(5,6+) (p = 0.02). AP zone metastases alone had a significantly worse survival than N1(single) (p = 0.008), whereas there was no statistically significant difference between the N1(multiple) and N2(5,6+) (p = 0.248). N2(7+) was not expected to survive 3 years after operation. They had a significantly worse prognosis than N2(5,6+) (p = 0.02). LUL tumors with metastasis in the AP zone lymph nodes, especially skip metastasis, were associated with a more favorable prognosis than other mediastinal lymph nodes. However, the therapy of choice for lung cancer with N2(5,6+) has not been clarified yet. Georg Thieme

    serum against SBC-3/DOX cells to a similar extent compared with parental SBC-3 cells. Pretreatment of human effector cells with various cytokines induced further enhancement of the KM966-dependent ADCC against SBC-3/DOX cells. Intravenous injection of SBC-3 or SBC-3/DOX cells into natural killer (NK) cell-depleted severe combined immunodeficient (SCID) mice developed metastases in multiple organs (liver, kidneys and lymph nodes). Interestingly, SBC-3/DOX cells produced metastases more rapidly than SBC-3 cells, suggesting more aggressive phenotype of SBC-3/DOX cells than their parental cells in vivo. Systemic treatment with KM966, given on days 2 and 7, drastically inhibited the formation of multiple-organ metastases produced by both SBC-3 and SBC-3/DOX cells, indicating that KM966 can eradicate metastasis by SCLC cells irrespective of MDR phenotype. These findings suggest that the mouse-human chimeric KM966 targets the GM2 antigen, and might be useful for the immunological circumvention of multiple-organ metastases of refractory SCLC.

    Full Text Available Extrahepatic spread of hepatocellular carcinoma (HCC is uncommon; and, pelvic metastasis, in particular, is extremely rare. A 71-year-old woman was admitted for evaluation of pelvic solitary solid mass. She had undergone a left lobectomy 28 years previously. Magnetic resonance imaging of the abdomen and pelvis demonstrated a heterogeneous mass in the right pelvic cavity, whereas no space-occupying lesions or ascites were detected in the liver. CA 125 levels were within normal limits; however, serum alpha-fetoprotein levels were markedly elevated. She underwent laparoscopic pelvic mass excision, total hysterectomy, and bilateral salpingo-oophorectomy. Histopathologic findings and immunochemical staining results indicated metastatic HCC. Herein, we report an unusual case of a patient with solitary recurrence in the pelvic cavity 28 years after initial diagnosis and treatment.

    We studied 44 patients with focal benign (n = 13) or malignant (n = 31) liver tumors proved by histology or follow-up. The flow mode was acquired by electron beam CT (EBCT) after injection (35 cc at 6 ml/sec): 20 slices with a 400 ms exposure time. We looked for abnormal vessels and density curves inside the tumor, liver and aorta. We describe arterial vascularization in most cases (type 1) and particularly in all the hepatocarcinomas (n = 15) associated with abnormal vessels, and also in rare tumors (n = 4). For benign lesions like angiomas (n = 9) we showed surrounding the mass arterial vascularization in add to the typical aspect (type 3); for nodular hyperplasia (n = 3) arterial blush was associated with the last part of the tumoral curve at the same level as liver. Most often metastasis (n = 13) had no central vascularization and a slight peripheral density increased (type 2). Flow mode by EBCT allows a good density curves analysis particularly at arterial time. (authors). 20 refs., 12 figs

    in an adult patient with IF secondary to severe Crohn's disease and multiple small bowel resections. The patient developed liver dysfunction and pathology consistent with IFALD. Multiple causal factors were implicated, including nutrition-related factors, catheter sepsis and the use of hepatotoxic medications....... Multidisciplinary treatment in a tertiary IF referral centre included aggressive sepsis management, discontinuation of hepatotoxic medications and a reduction of parenteral nutrition dependency through optimisation of enteral nutrition via distal enteral tube feeding. Upon this, liver function tests normalised....

    Objective: To investigate the pathway and MRI findings of meningeal metastasis original from lung cancer. Methods: 44 cases with cerebro-spinal meningeal metastasis original from lung cancer proven by clinical and pathology were retrospectively reviewed. All cases undergone plain MRI scan and Gd-DTPA enhanced MRI scan on brain and/or spine. Results: MRI plain scan indicated 28 cases with brain metastases, 3 cases with meningeal nodosity or irregularly patchy abnormal signal, 1 case with nodule in left cavernous sinus, 10 cases with abnormal signal in spine, 2 cases with abnormal signal in spinal dura mater. 34 cases with cerebro meningeal metastases were found in MRI enhancement scan. Among them, 11 cases displayed cerebral dura mater-arachnoid enhancement, 17 cases revealed cerebral pia mater-arachnoid enhancement and 6 cases with mixed typed enhancement. Osteoclasia in skull was found in 4 cases, spinal metastasis was revealed in 17 cases, and patchy abnormal enhancement in spinal dura mater was showed in 12 cases. Conclusion: Hematogenous metastasis is a main route of meningeal metastasis caused by lung cancer and enhanced MRI scan is of important diagnostic value. (authors)

    Full Text Available Abstract Background Promotion of endothelial normalization restores tumor oxygenation and obstructs tumor cells invasion, intravasation, and metastasis. We therefore investigated whether a vasoactive drug, tanshinone IIA, could inhibit metastasis by inducing vascular normalization after palliative resection (PR of hepatocellular carcinoma (HCC. Methods A liver orthotopic double-tumor xenograft model in nude mouse was established by implantation of HCCLM3 (high metastatic potential and HepG2 tumor cells. After removal of one tumor by PR, the effects of tanshinone IIA administration on metastasis, tumor vascularization, and survival were evaluated. Tube formation was examined in mouse tumor-derived endothelial cells (TECs treated with tanshinone IIA. Results PR significantly accelerated residual hepatoma metastases. Tanshinone IIA did not inhibit growth of single-xenotransplanted tumors, but it did reduce the occurrence of metastases. Moreover, it inhibited PR-enhanced metastases and, more importantly, prolonged host survival. Tanshinone IIA alleviated residual tumor hypoxia and suppressed epithelial-mesenchymal transition (EMT in vivo; however, it did not downregulate hypoxia-inducible factor 1α (HIF-1α or reverse EMT of tumor cells under hypoxic conditions in vitro. Tanshinone IIA directly strengthened tube formation of TECs, associated with vascular endothelial cell growth factor receptor 1/platelet derived growth factor receptor (VEGFR1/PDGFR upregulation. Although the microvessel density (MVD of residual tumor tissue increased after PR, the microvessel integrity (MVI was still low. While tanshinone IIA did not inhibit MVD, it did dramatically increase MVI, leading to vascular normalization. Conclusions Our results demonstrate that tanshinone IIA can inhibit the enhanced HCC metastasis associated with PR. Inhibition results from promoting VEGFR1/PDGFR-related vascular normalization. This application demonstrates the potential clinical
