    Between June 1973 and November 1980, 1,171 patients with metastatic breast cancer were treated with various doxorubicin-containing regimens at our institution (M.D. Anderson Hospital and Tumor Institute, Houston). Retrospective analysis of all 233 cases (20%) with liver metastases was done to correlate various clinical and biochemical characteristics with response to treatment, survival, and causes of death. A similar analysis was performed for 58 consecutive patients with liver metastases treated at this hospital between December 1955 and December 1957 with hormone therapy or single-agent chemotherapy. Objective responses were observed in 132 of 233 patients (57%) treated with combination chemotherapy. The median survival was 14 months in the 1970s and 5 months in the 1950s. Among patients who had liver metastases at the time of initial diagnosis of breast cancer, survival was longer for the group treated with combination chemotherapy. All cases were classified according to the number of organ sites involved by metastases. Patients with only liver metastases, or liver plus bone lesions had the longest survival. Other clinical and biochemical factors that correlated significantly with longer survival were: no prior chemotherapy, performance status of 1 to 2, absence of ascites, normal bilirubin and lactic dehydrogenase (LDH), SGOT less than or equal to 2 times normal and albumin greater than 4.5 g/dL. The main cause of death was multiorgan failure, with only 20% of patients dying of liver failure. The present study shows that the presence of liver metastases in breast cancer is not by itself an ominous factor. Most patients respond to therapy, and significant palliation with extended survival is possible for several prognostic subgroups. Further improvement in length and quality of survival is expected with earlier diagnosis.

    Rectal cancer is a common entity and often presents with synchronous liver metastases. There are discrepancies in management guidelines throughout the world regarding the treatment of advanced rectal cancer, which are further compounded when it presents with synchronous liver metastases. The following article examines the evidence regarding treatment options for patients with synchronous rectal liver metastases and suggests potential treatment algorithms.

    The purpose was to evaluate the clinical results of stereotactic radiotherapy in primary liver tumors and hepatic metastases. Five patients with primary liver cancer and 39 patients with 51 hepatic metastases were treated by stereotactic radiotherapy since 1997. Twenty-eight targets were treated in a 'low-dose'-group with 3x10 Gy (n=27) or 4x7 Gy (n=1) prescribed to the PTV-encl. 65%-isodose. In a 'high-dose'-group patients were treated with 3x12 - 12.5 Gy (n=19; same dose prescription) or 1x26 Gy/PTV-enclosing 80%-isodose (n=9). Median follow-up was 15 months (2-48 months) for primary liver cancer and 15 months (2-85 months) for hepatic metastases. While all primary liver cancers were controlled, nine local failures (3-19 months) of 51 metastases were observed resulting in an actuarial local control rate of 92% after 12 months and 66% after 24 months and later. A borderline significant correlation between dose and local control was observed (p=0.077): the actuarial local control rate after 12 and 24?months was 86% and 58% in the low-dose-group versus 100% and 82% in the high-dose-group. In multivariate analysis high versus low-dose was the only significant factor predicting local control (p=0.0089). Overall survival after 1 and 2 years was 72% and 32% for all patients and was impaired due to systemic progression of disease. No severe acute or late toxicity exceeding RTOG/EORTC-score 2 were observed. Stereotactic irradiation of primary liver cancer and hepatic metastases offers a locally effective treatment without significant complications in patients, who are not amenable for surgery. Patient selection is important, because those with low risk for systemic progression are more likely to benefit from this approach.

    The liver is the commonest site of distant metastasis ofcolorectal cancer and nearly half of the patients withcolorectal cancer ultimately develop liver involved duringthe course of their diseases. Surgery is the only therapythat offers the possibility of cure for patients with hepaticmetastatic diseases. Five-year survival rates after resectionof all detectable liver metastases can be up to 40 %.Unfortunately, only 25 % of patients with colorectal livermetastases are candidates for liver resection, while the othersare not amenable to surgical resection. Regional therapiessuch as radiofrequency ablation and cryotherapy may beoffered to patients with isolated unresectable metastasesbut no extrahepatic diseases. Hepatic artery catheterchemotherapy and chemoembolization and portal veinembolization are often used for the patients with extensiveliver metastases but without extrahepatic diseases, whichare not suitable for regional ablation. For the patients withmetastatic colorectal cancer beyond the liver, systemicchemotherapy is a more appropriate choice. Immunotherapyis also a good option when other therapies are used incombination to enhance the efficacy. Selective internalradiation therapy is a new radiation method which can beused in patients given other routine therapies Without effects.

    OBJECTIVE:: The primary objective was to compare overall survival (OS) in patients with colorectal cancer (CRC) with nonresectable liver-only metastases treated by liver transplantation or chemotherapy. BACKGROUND:: CRC is the third most common cancer worldwide. About 50% of patients will develop...... metastatic disease primarily to the liver and the lung. The majority of patients with liver metastases receive palliative chemotherapy, with a median OS of trial patients of about 2 years, and less than 10% are alive at 5 years. METHODS:: Patients with nonresectable liver-only CRC metastases underwent liver...... transplantation in the SECA study (n = 21). Disease-free survival (DFS) and OS of patients included in the SECA study were compared with progression-free survival (PFS) and OS in a similar cohort of CRC patients with liver-only disease included in a first-line chemotherapy study, the NORDIC VII study (n = 47...

    We report a case of a 61-year-old man who presented with fatigue, abdominal pain and hepatomegaly. Computed tomography (CT) of the abdomen showed hepatomegaly and multiple hepatic lesions highly suggestive of metastatic diseases. Due to the endoscopic finding of colon ulcer, colon cancer with liver metastases was suspected. Biochemically a slight increase of transaminases, alkaline phosphatase and gammaglutamyl transpeptidase were present; α-fetoprotein, carcinoembryogenic antigen and carbohydrate 19-9 antigen serum levels were normal. Laboratory and instrumental investigations, including colon and liver biopsies revealed no signs of malignancy. In the light of spontaneous improvement of symptoms and CT findings, his personal history was revaluated revealing direct contact with pigs and their tissues. Diagnosis of leptospirosis was considered and confirmed by detection of an elevated titer of antibodies to leptospira. After two mo, biochemical data, CT and colonoscopy were totally normal.

    To determine the prognostic and predictive value of liver volume in colorectal cancer patients with unresectable liver metastases. Sixteen patients received whole liver radiotherapy (WLRT) between January 1997 and June 2013. A total dose of 21 Gy was delivered in 7 fractions. The median survival time after WLRT was 9 weeks. In univariate analysis, performance status, serum albumin and total bilirubin level, liver volume and extrahepatic metastases were associated with survival. The mean liver volume was significantly different between subgroups with and without pain relief (3,097 and 4,739 mL, respectively; p = 0.002). A larger liver volume is a poor prognostic factor for survival and also a negative predictive factor for response to WLRT. If patients who are referred for WLRT have large liver volume, they should be informed of the poor prognosis and should be closely observed during and after WLRT.

    The liver is the most common site of distant metastases in patients with colorectal cancer. Surgery represents the mainstream for curative treatment of colorectal cancer liver metastases (CRCLM) with long-term survival up to 58 and 36 % at 5 and 10 years, respectively. Despite advances on diagnosis, staging and surgical strategies, 60-70 % of patients will develop recurrence of the disease even after R0 resection of CRCLM. Tumor staging, prognosis, and therapeutic approaches for cancer are most often based on the extent of involvement of regional lymph nodes (LNs) and, to a lesser extent, on the invasion of regional lymphatic vessels draining the primary tumor. For CRCLM, the presence of intra hepatic lymphatic and blood vascular dissemination has been associated with an increased risk of intra hepatic recurrence, poorer disease-free and overall survival after liver resection. Also, several studies have reviewed the role of surgery in the patient with concomitant CRCLM and liver pedicle LN metastasis. Although pedicle LN involvement is related to worst survival rates, it does not differentiate patients that will relapse from those that will not. This review aims to briefly describe the anatomy of the liver's lymphatic drainage, the incidence of intrahepatic lymphatic invasion and hilar lymph node involvement, as well as their clinical impact in CRCLM. A better understanding of the role of liver lymphatic metastasis might, in the near future, impact the strategy of systemic therapies after liver resection as for primary colorectal tumors.

    AIM: Liver metastases from breast cancer (BCLM) are associated with poor prognosis. Cytotoxic chemotherapy can result in regression of tumor lesions and a decrease in symptoms. Available data, in the literature, also suggest a subgroup of patients rraay berefit from surgery, but few talked about transcatheter arterial chemoembolization (TACE).We report the results of TACE and systemic chemotherapy for patients with liver metastases from breast cancer and evaluate the prognostic factors. METHODS: Forty-eight patients with liver metastases, from proved breast primary cancer were treated with TACEor systemic chemotherapy between January 1995 and December 2000. Treatment results were assessed according to WHO criteria, along with analysis of prognostic factors for survival using Cox regression model.RESULTS: The median follow-up was 28 mo (1-72 mo). Response rates were calculated for the TACE group and chemotherapy group, being 35.7% and 7.1%,respectively. The difference was significant. The one-, two- and three-year Survival rates for the TACE group were 63.04%, 30.35%, and 13.01%, and those for the systemic chemotherapy group were 33.88%, 11.29%, and 0%. According to univariate analysis, variables significantly associated with survival were the lymph node status of the primary cancer, the clinical stage of liver metastases, the Child-Pugh grade, loss of weight. Other factors such as age, the intervals between the primary to the metastases, the maximal diameter of the liver metastases, the number of liver metastases, extrahepatic metastasis showed no prognostic significances. These factors mentioned above such as the lymph node status of the primary cancer, the clinical stage of liver metastases, the Child-Pugh grade, loss of weight were also independent factors in multivariate analysis.CONCLUSION: TACE treatment of liver metastases from breast cancer may prolong survival in certain patients. This approach offers new promise for the curative treatment of the patients

    Liver metastases in colorectal cancer patients decreases the expected 5 year survival rates by a factor close to nine. It is generally accepted that resection of liver metastases should be attempted whenever feasible. This manuscript addresses the optimal therapeutic plan regarding timing of resection of synchronous liver metastases and the use of chemotherapy in combination with resection of synchronous metachronous liver metastases. The aim is to pool all published results in order to attribute a level of evidence to outcomes and identify lacking evidence areas. A systematic search of guidelines, reviews, randomised controlled, observational studies and updating a meta-analysis was performed. Data were extracted and analysed. Data failed to demonstrate an effect of timing of surgery or use of chemotherapy on overall survival. Concomitant resection of liver metastases and the primary tumour may result in lower postoperative morbidity. Systemic peri-operative chemotherapy may improve progression free survival compared to surgery alone.

    The liver is one of the commonest sites of metastatic involvement in breast cancer, usually evident as focal lesions on imaging tests. Rarely, the pattern of metastatic spread is so diffuse that it remains radiologically occult. Such patients usually present with signs of hepatic insufficiency without any focal lesions on liver imaging. In such cases, liver biopsy is required to make a definitive diagnosis. We report a case of a 56-year-old postmenopausal woman with metastatic breast cancer who presented with subacute progressive liver failure. Repeated imaging of the liver was normal or non-descript. Liver biopsy finally established the diagnosis of intrasinusoidal metastases from breast cancer.

    2012-02-01

    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.

    Abstract This study aimed to determine the prognostic effects of preoperative chemotherapy for colorectal cancer liver metastasis (CLM). We retrospectively evaluated 2 groups of patients between January 2006 and August 2012. A total of 53 patients who had ≥3 hepatic metastases underwent resection after preoperative chemotherapy (preoperative chemotherapy group), whereas 96 patients who had ≥3 hepatic metastases underwent resection with a curative intent before chemotherapy for CLM (primary resection group). A propensity score (PS) model was used to compare the both groups. The 3-year disease-free survival (DFS) rates were 31.7% and 20.4% in the preoperative chemotherapy and primary resection groups, respectively (log-rank = 0.015). Analyzing 32 PS matched pairs, we found that the DFS rate was significantly higher in the preoperative chemotherapy group than in the primary resection group (3-year DFS rates were 34.2% and 16.8%, respectively [log-rank = 0.019]). Preoperative chemotherapy group patients had better DFSs than primary resection group patients in various multivariate analyses, including crude, multivariable, average treatment effect with inverse probability of treatment weighting model and PS matching. Responses to chemotherapy are as important as achieving complete resection in cases of multiple hepatic metastases. Preoperative chemotherapy may therefore be preferentially considered for patients who experience difficulty undergoing complete resection for multiple hepatic metastases. PMID:28207557

    Full Text Available Aim. Differential immunohistochemical parameters of primary liver cancer and liver metastases of ductal pancreatic cancer (DPC were studied in puncture trephine biopsy of the liver of 23 patients with hepatocellular carcinoma (HCC, 2 patients combined hepato-cholangiocellular cancer (CHCC, 15 patients cholangiocellular cancer (CCC and 12 patients with metastatic DPC. Results. It was found that HCC liver is characterized by high levels of expression of HepPar 1 and alpha-fetoprotein, the lack of expression of MUC1 mucins, MUC5AC and CA125, and variable expression of CK8, CK7, SK19 and CK20, which depends on the degree of tumor differentiation and embodiment. Cholangiocellular liver cancer differs from others expressed desmoplastic stroma, high levels of expression of cytokeratins 7 and 19, MUC1 and MUC5AC, lack expression of HepPar 1 and variable expression of alpha-fetoprotein, cytokeratin 8 and20. Insolid and trabecular patterns of CHCC expression of HepRar 1, AFP and CK20 were determined, and in ductual patterne- CK7 and CK19 were determined. CCC and liver metastases of DPC which have the similar microstructure were characterized with the same spectrum characteristic of expressed cytokeratin (SK7, + 19, + 20, + and mucin (MUC1 + MUC5AC +, and variable expression of CA125 and CA19-9. Conclusion. Therefore, the differential diagnosis in immunohistochemistry of liver trepanobioptate between CCC and liver metastases of DPC is only possible based on the data of computed tomography or ultrasound examination of the liver and pancreas.

    Background Morphologic imaging after radiofrequency ablation (RFA) of liver metastases is hampered by an inflammatory response in the ablation margin, making the identification of local tumor progression (LTP) difficult. The aim of this study was to evaluate the efficacy of early 18F-FDG PET/CT scanning to monitor the effectiveness of RFA in colorectal liver metastases.Methods Twelve patients with 20 metastases were treated with RFA for colorectal liver metastases. They underwent PET/CT within 2 weeks before RFA and within 24 hours after RFA (so termed "early PET/CT"). PET/CT was repeated at 1, 3, and 6 months, and then every 6 months after ablation. The standard of reference was based on available clinical and radiological follow-up data.Results Early PET/CT revealed total photopenia in 16 RFA-treated metastases, which were found to be without residual tumor on the final PET/CT scan. Three RFA-treated metastases with focal uptake were identified as local tumor progression, which necessitated further treatment. One RFA-treated metastasis with rim-shaped uptake was regarded as inflammation. The results of the early PET/CT scanning were consistent with the findings of the final follow-up. Conclusions PET/CT performed within 24 hours after RFA can effectively detect whether residual tumor exists for colorectal cancer liver metastases. The results can guide further treatment, and may improve the efficacy of RFA.

    We present a case of a 72-year-old man with a common bile duct cancer, who was initially believed to have multiple liver metastases based on computed tomography findings, and in whom magnetic resonance cholangiography (MRC) revealed a diagnosis of bile duct hamartomas. At exploration for pancreaticoduodenectomy, liver palpation revealed disseminated nodules at the surface of the liver. These nodules showed gray-white nodular lesions of about 0.5cm in diameter scattered on the surface of both liver lobes, which were looked like multiple liver metastases from bile duct cancer. Frozen section of the liver biopsy disclosed multiple bile ducts with slightly dilated lumens embedded in the collagenous stroma characteristics of multiple bile duct hamartomas (BDHs). Only two reports have described the MRC features of bile duct hamartomas. Of all imaging procedures, MRC provides the most relevant features for the imaging diagnosis of bile duct hamartomas.

    Full Text Available Abstract Background Accurate staging of colorectal cancer (CRC with clinicopathological parameters is important for predicting prognosis and guiding treatment but provides no information about organ site of metastases. Patterns of genomic aberrations in primary colorectal tumors may reveal a chromosomal signature for organ specific metastases. Methods Array Comparative Genomic Hybridization (aCGH was employed to asses DNA copy number changes in primary colorectal tumors of three distinctive patient groups. This included formalin-fixed, paraffin-embedded tissue of patients who developed liver metastases (LM; n = 36, metastases (PM; n = 37 and a group that remained metastases-free (M0; n = 25. A novel statistical method for identifying recurrent copy number changes, KC-SMART, was used to find specific locations of genomic aberrations specific for various groups. We created a classifier for organ specific metastases based on the aCGH data using Prediction Analysis for Microarrays (PAM. Results Specifically in the tumors of primary CRC patients who subsequently developed liver metastasis, KC-SMART analysis identified genomic aberrations on chromosome 20q. LM-PAM, a shrunken centroids classifier for liver metastases occurrence, was able to distinguish the LM group from the other groups (M0&PM with 80% accuracy (78% sensitivity and 86% specificity. The classification is predominantly based on chromosome 20q aberrations. Conclusion Liver specific CRC metastases may be predicted with a high accuracy based on specific genomic aberrations in the primary CRC tumor. The ability to predict the site of metastases is important for improvement of personalized patient management.

    2012-01-01

    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.

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.

    Full Text Available Objective: The purpose of this study was to assess the resectability and effectiveness of repeat hepatectomy for relapsing liver metastases of colorectal origin in terms of morbidity, mortality, overall survival, and disease-free survival. Methods: A retrospective study was performed on a prospective cohort of patients with colorectal liver metastases who underwent repeat surgery at Hospital Universitario San Cecilio, Granada (Spain, from March 2003 to June 2013. Primary outcome variables included survival and morbidity within 30 days post-surgery. Results: A total of 147 patients with colorectal liver metastases underwent surgical excision during the study period; 61 patients had liver recurrence, and 34 of these received repeat surgery. The overall survival rate at 5 and 10 years for resected patients (n = 27/34 was 48% and 48%. Mean hospital stay was 8.9 ± 3.5 days, morbidity was 9%, and mortality was 0%. Conclusion: Repeat liver resection for colorectal liver metastases is a safe, effective surgical procedure whose results are similar to those obtained after initial liver resection.

    It is now common to resect colorectal cancer by laparoscopic surgery. Hepatectomy has become a standard treatment for patients with colorectal cancer with resectable liver metastases. The resection of liver tumors can now be done partly by laparoscopic surgery. However, metastatic tumors in the right lobe are often difficult to resect laparoscopically. Furthermore, simultaneous resection of the colorectum and liver may also be difficult. In this study, we evaluated a new method to resect both colorectal cancer and liver metastases in the right lobe by laparoscopic surgery. Two cases are presented that underwent total laparoscopic resection of a right lobe tumor, associated with laparoscopic colorectal resection. The metastatic tumor in the right lobe was first resected in the left hemi-prone position. Then, the colorectal cancer was resected in the lithotomy position. The method for resecting the right lobe liver tumor and colorectal cancer was safe and feasible. The mean duration of surgery was 443.5 min, and the mean blood loss was 158 mL. The postoperative course was uneventful. In selected patients, laparoscopic hepatectomy for right lobe synchronous metastatic tumors can be safely performed simultaneously with colorectal surgery.

    Although simultaneous resection of primary colorectal cancer and synchronous liver metastases is reported to be safe and effective, the feasibility of a laparoscopic approach remains controversial. This study evaluated the safety, feasibility, and short-term outcomes of simultaneous laparoscopic surgery for primary colorectal cancer with synchronous liver metastases. From September 2008 to December 2013, 10 patients underwent simultaneous laparoscopic resection of primary colorectal cancer and synchronous liver metastases with curative intent at our institute. The median operative time was 452 minutes, and the median estimated blood loss was 245 mL. Median times to discharge from the hospital and adjuvant chemotherapy were 13.5 and 44 postoperative days, respectively. Negative resection margins were achieved in all cases, with no postoperative mortality or major morbidity. Simultaneous laparoscopic colectomy and hepatectomy for primary colorectal cancer with synchronous liver metastases appears feasible with low morbidity and favorable outcomes.

    The aim of this study is to provide a diagnostic performance evaluation of contrast-enhanced ultrasonography (CEUS) in detecting liver metastases in patients with suspected of pancreatic or periampullary cancer. Computed tomography (CT) is often insufficient for detection of liver metastases, but their presence plays a crucial role in the choice of therapy. Eighty-nine patients with suspected pancreatic or periampullary cancer were included in this prospective study with retrospective analysis. Patients underwent an abdominal CT and CEUS. Fifteen patients had liver metastases. The CT sensitivity was 73.3% (11/15), the specificity 93.2% (69/74), the positive predictive value (PPV) 68.8% (11/16) and the negative predictive value (NPV) 94.6% (69/73). Based on CEUS, the sensitivity was 80% (12/15), specificity 98.6% (73/74), PPV 92.3% (12/13) and NPV 96.1% (73/76). CEUS improved characterization of liver lesions in patients with suspected pancreatic or periampullary cancer compared with CT. CEUS can better detect benign liver lesions and distinguish false-positive or indeterminate CT results.

    Pancreatic cancer patients underwent surgical resection often present distant metastases early after surgery. Detection of circulating tumor cells (CTCs) has been correlated to a worse oncological outcome in patients with advanced pancreatic cancer. The objective of this pilot study is to investigate the possible prognostic role of CTCs in patients undergoing surgery for pancreatic cancer. In 20 patients undergoing pancreatic resection, 10 mL blood sample was collected intraoperatively from both systemic circulation (SC) and portal vein (PV). Blood sample was analyzed for CTCs with CellSearch® system. All patients underwent an oncologic follow-up for at least 3 years, quarterly. CTCs were detected in nine (45%) patients: five patients had CTCs in PV only, three patients in both SC and PV, and one patient in SC only. CTC-positive and CTC-negative patients were similar for demographics and cancer stage pattern. No significant differences were found in both overall and disease-free survival between CTC-positive and CTC-negative patients. At 3-year follow-up, portal vein CTC-positive patients presented a higher rate of liver metastases than CTC-negative patients (53 vs. 8%, p = 0.038). CTCs were found in 45% of the patients. No correlation between CTCs and survival was found. The presence of CTCs in portal vein has been associated to higher rate of liver metastases after surgery.

    Metastatic growth by colorectal cancer cells in the liver requires the ability of the cancer cells to interact with the new microenvironment. This interaction results in three histological growth patterns of liver metastases: desmoplastic, pushing, and replacement. In primary colorectal cancer several proteases, involved in the degradation of extracellular matrix components, are up-regulated. In liver metastases, their expression is growth pattern dependent. Tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) is a strong prognostic marker in plasma from colorectal cancer patients, with significant higher levels in patients with metastatic disease. We therefore wanted to determine the expression pattern of TIMP-1 in primary colorectal cancers and their matching liver metastases. TIMP-1 mRNA was primarily seen in α-smooth-muscle actin (α-SMA)-positive cells. In all primary tumors and liver metastases with desmoplastic growth pattern, TIMP-1 mRNA was primarily found in α-SMA-positive myofibroblasts located at the invasive front. Some α-SMA-positive cells with TIMP-1 mRNA were located adjacent to CD34-positive endothelial cells, identifying them as pericytes. This indicates that TIMP-1 in primary tumors and liver metastases with desmoplastic growth pattern has dual functions; being an MMP-inhibitor at the cancer periphery and involved in tumor-induced angiogenesis in the pericytes. In the liver metastases with pushing or replacement growth patterns, TIMP-1 was primarily expressed by activated hepatic stellate cells at the metastasis/liver parenchyma interface. These cells were located adjacent to CD34-positive endothelial cells, suggesting a function in tumor-induced angiogenesis. We therefore conclude that TIMP-1 expression is growth pattern dependent in colorectal cancer liver metastases.

    Breast cancer liver metastases (BCLM) are not uncommon (about 18% of cases): although some patients have been reported as still living after 25 months, median survival after hormonal- or chemotherapy is 6-14 months. In recent years, new chemotherapy regimens and molecular targeted therapies have given medical oncologists reason to believe that metastatic disease can be eradicated, or at least controlled for prolonged periods. In an attempt to improve survival, consideration has also been given to loco-regional treatments such as hepatic resection and radio-frequency ablation, which have been associated with better outcomes in selected patients. This review considers the role of two loco-regional approaches in a multidisciplinary perspective in the treatment of single or multiple breast cancer metastases limited to the liver. An expanded role for hepatic resection and ablation is being investigated. We assessed available data in the literature to determine their role on survival outcomes. They suggest that loco-regional treatments might be of significant benefit in a selected group of women with BCLM, but the role of these local treatments in multimodality treatment of liver metastases remains controversial. It can generally be said that loco-regional treatments can improve overall survival, with no mortality and less than 20% morbidity in patients at low surgical risk; however, they should only be considered cytoreductive treatments and, as such, always need to be integrated with systemic therapy.

    A prospective phase II trial was conducted to evaluate the effectiveness and toxicity of regional hyperthermia and whole liver irradiation (WLI) for numerous chemorefractory liver metastases from colorectal cancer. Enrolled patients had numerous chemorefractory hepatic metastases from colorectal cancer. Five sessions of hyperthermia and seven fractions of 3-gray WLI were planned. Health-related quality of life (HRQoL) was determined using the Korean version of the European Organization for Research and Treatment of Cancer quality of life questionnaire C-30 and the Functional Assessment of Cancer Therapy-Hepatobiliary version 4.0. Objective and pain response was evaluated. A total of 12 patients consented to the study and the 10 who received WLI and hyperthermia were analyzed. WLI was completed as planned in nine patients and hyperthermia in eight. Pain response was partial in four patients and stable in four. Partial objective response was achieved in three patients (30.0%) and stable disease was seen in four patients at the 1-month follow-up. One patient died 1 month after treatment because of respiratory failure related to pleural metastasis progression. Other grade III or higher toxicities were detected in three patients; however, all severe toxicities were related to disease progression rather than treatment. No significant difference in HRQoL was noted at the time of assessment for patients who were available for questionnaires. Combined WLI and hyperthermia were well tolerated without severe treatment-related toxicity with a promising response from numerous chemorefractory hepatic metastases from colorectal cancer.

    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.

    Full Text Available Abstract Background To investigate whether whole-liver radiotherapy (RT is beneficial in end-stage colorectal cancer with massive liver metastases and severe hepatic dysfunction. Methods Between June 2004 and July 2008, 10 colorectal cancer patients, who exhibited a replacement of over three quarters of their normal liver by metastatic tumors and were of Child-Pugh class B or C in liver function with progressive disease after undergoing chemotherapy, underwent whole-liver RT. RT was administered using computed tomography-based three-dimensional planning and the median dose was 21 Gy (range, 21-30 in seven fractions. Improvement in liver function tests, defined as a decrease in the levels within 1 month after RT, symptom palliation, toxicity, and overall survival were analyzed retrospectively. Results Levels of alkaline phosphatase, total bilirubin, aspartate transaminase, and alanine transaminase improved in 8, 6, 9, and all 10 patients, respectively, and the median reduction rates were 42%, 68%, 50%, and 57%, respectively. Serum carcinoembryonic antigen level decreased after RT in three of four assessable patients. For all patients, pain levels decreased and acute toxicity consisted of nausea/vomiting of grade ≤ 2. Further chemotherapy became possible in four of 10 patients. Mean survival after RT was 80 ± 80 days (range, 20-289; mean survival for four patients who received post-RT chemotherapy was 143 ± 100 days (range, 65-289, versus 38 ± 16 days (range, 20-64 for the six patients who did not receive post-RT chemotherapy (p = 0.127. Conclusions Although limited by small case number, this study demonstrated a possible role of whole-liver RT in improving hepatic dysfunction and delaying mortality from hepatic failure for end-stage colorectal cancer patients with massive liver metastases. Further studies should be followed to confirm these findings.

    Objective: To evaluate the local tumor control and survival data after transarterial chemoembolization with different drug combinations in the palliative treatment of patients with liver metastases of gastric cancer. Materials and methods: The study was retrospectively performed. 56 patients (mean age, 52.4) with unresectable liver metastases of gastric cancer who did not respond to systemic chemotherapy were repeatedly treated with TACE in 4-week intervals. In total, 310 chemoembolization procedures were performed (mean, 5.5 sessions per patient). The local chemotherapy protocol consisted of mitomycin alone (30.4%), mitomycin and gemcitabine (33.9%), or mitomycin, gemcitabine and cisplatin (35.7%). Embolization was performed with lipiodol and starch microspheres. Local tumor response was evaluated by MRI according to RECIST. Survival data from first chemoembolization were calculated according to the Kaplan–Meier method. Results: The local tumor control was: complete response in 1.8% (n = 1), partial response in 1.8% (n = 1), stable disease in 51.8% (n = 29) and progressive disease in 44.6% (n = 25) of patients. The 1-, 2-, and 3-year survival rate from the start of chemoembolization were 58%, 38%, and 23% respectively. The median and mean survival times were 13 and 27.1 months. A Statistically significant difference between patients treated with different chemotherapy protocols was noted (ρ = 0.045) with the best survival time in the mitomycin, gemcitabine and cisplatin group. Conclusion: Transarterial chemoembolization is a minimally invasive therapy option for palliative treatment of liver metastases in patients with gastric cancer.

    To compare the sensitivity of MRI to detect colorectal cancer liver metastases (CRLM) after ingestion of manganese-based contrast agent (CMC-001) with that of a comprehensive intravenous gadobenate dimeglumine protocol, and to assess the safety and acceptability of oral manganese. 20 patients suspected of having 1-6 CRLM were included prospectively in this randomised cross-over study. Liver MRI was performed with a one-week interval at 1.5 T and included T1-w VIBE and T2-HASTE, before and after administration of 1.6 g CMC-001 or 0.1 mmol/kg gadobenate dimeglumine. The metastasis-to-liver signal intensity (SI) ratio was calculated. Standard of reference was histopathology after surgery, or combination of other imaging studies and/or follow up. Adverse events (AE) and clinicolaboratory tests were monitored. Of 44 metastases, 41 were detected after CMC-001 (93%) and 42 after gadobenate dimeglumine (95%). Fifteen false-positive lesions were found after CMC-001 and 2 after gadobenate dimeglumine. The metastasis-to-liver SI ratio was significantly higher after CMC-001 than after gadobenate dimeglumine (0.51 and 0.21 respectively, P < 0.0001). More AE occurred after manganese compared to gadobenate dimeglumine. CMC-001 is as sensitive as an extensive intravenous gadobenate dimeglumine protocol in detecting CRLM. It was relatively well tolerated but had higher rates of gastrointestinal AE. (orig.)

    A 70-year-old man who was diagnosed with unresectable advanced rectal cancer with multiple liver metastases, received oxaliplatin-based treatment with bevacizumab as first-line chemotherapy and irinotecan-based treatment with bevacizumab as second-line chemotherapy for a total of 17 months. The patient was treated with regorafenib (160 mg/day for 3 weeks) as third-line chemotherapy. Following completion of one course of regorafenib treatment, the patient complained of abdominal distension. Computed tomography (CT) examination identified liver atrophy and massive ascites, while no such symptoms were observed prior to the regorafenib treatment. Blood testing revealed increases in the aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) levels. The patient was admitted to the Aizu Medical Center (Aizuwakamatsu, Japan). Approximately 2,000 ml of ascitic fluid were aspirated daily for 1 week by abdominal puncture. The patient was administered oral diuretics, including 20 mg/day of furosemide and 25 mg/day of spironolactone. Albumin was administered to correct the albumin deficit. The levels of AST, ALT and ALP were decreased from the peak value reported on admission and the patient was discharged from our hospital 16 days following treatment initiation. The CT examination after 1 month revealed that the volume of the liver had been restored and the ascites had disappeared. Furthermore, almost all the liver metastases were reduced in size. The carcinoembryonic antigen level, which was elevated prior to regorafenib treatment, also decreased to normal.

    Approximately half of patients with colorectal cancer present with liver metastases during the course of their disease, which directly affect prognosis and is responsible for two thirds of deaths related to the disease. In the last two decades the treatment of liver metastases from colorectal cancer (CRCLM) provided significant gain in survival when all treatment options are available to the patient. In this context, surgical treatment remains as the only chance of cure, with five-year survival rates of 25-58%. However, only 1/4 of the patients have resectable disease at diagnosis. For this reason, one of the key points in the current management of patients with CRCLM is the development of strategies that facilitate complete resection of liver lesions. The advent and refinement of ablative methods have expanded the possibilities of surgical therapy. The emergence of new chemotherapy regimens and the introduction of targeted therapies has provided high response rates and has permanently altered the management of these patients. The multimodal therapy and the involvement of different medical specialties has increasingly enabled CRCLM treatment to approached the ideal treatment, i.e., an individualized one. Based on an extensive review of literature and on experience from some of the most important specialized centers of Brazil, the São Paulo Liver Club began a process of multi-institutional discussions that resulted in the recommendations that follow. These recommendations, however, are not intended to be absolute, but useful tools in the therapeutic decision process for this complex group of patients.

    Objective: To evaluate the association between p53 codon 72 polymorphism (R72P) and the risk of colorectal liver metastases. Methods: The p53 R72P genotype was identified by polymerase chain reaction-restriction fi'agment length poly-morphism (PCR-RFLP) method in 78 consecutive colorectal cancer patients with liver metastases and 214 age- and sex-matched cases with nonmetastatic colorectai cancer. Results: The R allele of the p53 R72P polymorphism was more frequently found in metastatic cases than in nonmetastatic cases (P=0.075). Carriers of the 72R allele had a 2.25-fold (95% CI (confidence inter-val)=1.05~4.83) increased risk of liver metastases. On the stratification analysis, 72R-carrying genotype conferred a 3.46-fold (95% CI=1.02~11.72) and a 1.05-fold (95% CI=0.36~3.08) increased risk of liver metastases for p53 overexpression-positive and negative colorectal cancers, respectively. Conclusion: These results demonstrate for the first time that the 72R allele of the p53 polymorphism has an increased risk for liver metastases in colorectal cancers positive for p53 overexpression.

    The purpose of this study was to evaluate the efficacy of transarterial chemoembolization (TACE) using different drug combinations in the treatment of breast cancer liver metastases in terms of local tumor control and survival rate. A total of 208 patients (mean age 56.4 years, range 29-81) with unresectable hepatic metastases of breast cancer were repeatedly treated with TACE at 4-week intervals. In total, 1,068 chemoembolizations were performed (mean 5.1 sessions/patient, range 3-25). The chemotherapy protocol consisted of mitomycin-C only (8 mg/m{sup 2}; n=76), mitomycin-C with gemcitabine (n=111), and gemcitabine only (1,000 mg/m{sup 2}; n=21). Embolization was performed with lipiodol and starch microspheres. Tumor response was evaluated by MRI according to RECIST criteria. Survival rates were calculated using Kaplan-Meier method. For all protocols, local tumor control was partial response 13% (27/208), stable disease 50.5% (105/208), and progressive disease 36.5% (76/208). The 1-, 2-, and 3-year survival rates after TACE were 69, 40, and 33%. Median and mean survival times from the start of TACE were 18.5 and 30.7 months. Treatment with mitomycin-C only showed median and mean survival times of 13.3 and 24 months, with gemcitabine only they were 11 and 22.3 months, and with a combination of mitomycin-C and gemcitabine 24.8 and 35.5 months. TACE is an optional therapy for treatment of liver metastases in breast cancer patients with better results from the combined chemotherapy protocol. (orig.)

    Purpose Surgical resection of isolated hepatic or pulmonary metastases of colorectal cancer is an established procedure, with a 5-year survival rate of about 50%. However, the role of surgical resections in patients with both hepatic and pulmonary metastases is not well established. We aimed to analyze overall survival of these patients and associated factors. Methods Data retrospectively collected from 66 patients who underwent both hepatic and pulmonary metastasectomy after colorectal cancer surgery from August 2002 through August 2013 were analyzed. In univariate analysis, the log-rank test compared patient survival between groups. P < 0.1 was considered indicative of significance. Multivariate analysis of the significance data using a Cox proportional hazard model identified factors associated with overall survival. The synchronous group (n = 57) was defined as patients who had metastasectomy within 3 months from primary colorectal cancer surgery. The remaining nine patients constituted the metachronous group. Results Median follow-up was 126 months from the primary colorectal cancer surgery. The 5-year survival was 73.4%. There was no difference in overall survival between the synchronous and metachronous groups, consistent with previous studies. Distribution (involving one hemiliver or both, P = 0.010 in multivariate analysis) of liver metastases and multiplicity of the pulmonary metastasis (P = 0.039) were predictors of poor prognosis. Conclusion Sequential or simultaneous resection of both hepatic and pulmonary metastasis of colorectal cancer resulted in good long-term survival in selected patients. Thus, an aggressive surgical approach and multidisciplinary decision making with surgeons seems to be justified. PMID:28203555

    As many as 25 % of colorectal cancer (CRC) patients have liver metastases at presentation. However, the optimal strategy for resectable synchronous colorectal liver metastasis remains controversial. Despite the increasing use of laparoscopy in colorectal and liver resections, combined laparoscopic resection of the primary CRC and synchronous liver metastasis is rarely performed. The potential benefits of this approach are the possibility to perform a radical operation with small incisions, earlier recovery, and reduction in costs. The aim of this study was to review the literature on feasibility and short-term results of simultaneous laparoscopic resection. We conducted a systematic search of all articles published until February 2013. Search terms included: hepatectomy [Mesh], "liver resection," laparoscopy [Mesh], hand-assisted laparoscopy [Mesh], surgical procedures, minimally invasive [Mesh], colectomy [Mesh], colorectal neoplasms [Mesh], and "colorectal resections." No randomized trials are available. All data have been reported as case reports, case series, or case-control studies. Thirty-nine minimally invasive simultaneous resections were identified in 14 different articles. There were 9 (23 %) major hepatic resections. The most performed liver resection was left lateral sectionectomy in 26 (67 %) patients. Colorectal resections included low rectal resections with total mesorectal excision, right and left hemicolectomies, and anterior resections. Despite the lack of high-quality evidence, the laparoscopic combined procedure appeared to be feasible and safe, even with major hepatectomies. Good patient selection and refined surgical technique are the keys to successful simultaneous resection. Simultaneous left lateral sectionectomy associated with colorectal resection should be routinely proposed.

    Full Text Available Abstract Background Pancreatic cancer is the fourth leading cause of tumour death in the western world. However, appropriate tumour models are scarce. Here we present a syngeneic murine pancreatic cancer model using 7 Tesla MRI and evaluate its clinical relevance and applicability. Methods 6606PDA murine pancreatic cancer cells were orthotopically injected into the pancreatic head. Liver metastases were induced through splenic injection. Animals were analyzed by MRI three and five weeks following injection. Tumours were detected using T2-weighted high resolution sequences. Tumour volumes were determined by callipers and MRI. Liver metastases were analyzed using gadolinium-EOB-DTPA and T1-weighted 3D-Flash sequences. Tumour blood flow was measured using low molecular gadobutrol and high molecular gadolinium-DTPA. Results MRI handling and applicability was similar to human systems, resolution as low as 0.1 mm. After 5 weeks tumour volumes differed significantly (p 3+/-243 mm3 with MRI (mean 918 mm3+/-193 mm3 with MRI being more precise. Histology (n = 5 confirmed MRI tumour measurements (mean size MRI 38.5 mm2+/-22.8 mm2 versus 32.6 mm2+/-22.6 mm2 (histology, p 3+/-56.7 mm3 after 5 weeks. Lymphnodes were also easily identified. Tumour accumulation of gadobutrol was significantly (p Conclusions This model permits monitoring of tumour growth and metastasis formation in longitudinal non-invasive high-resolution MR studies including using contrast agents comparable to human pancreatic cancer. This multidisciplinary environment enables radiologists, surgeons and physicians to further improve translational research and therapies of pancreatic cancer.

    Surgery is currently considered the treatment of choice for patients with colorectal cancer liver metastases (CRLM) when resectable. The majority of these patients can also benefit from systemic chemotherapy. Recently, local or regional therapies such as thermal ablations have been used with acceptable outcomes. We searched the medical literature to identify studies and reviews relevant to radiofrequency (RF) ablation, microwave (MW) ablation and laser-induced thermotherapy (LITT) in terms of local progression, survival indexes and major complications in patients with CRLM. Reviewed literature showed a local progression rate between 2.8 and 29.7 % of RF-ablated liver lesions at 12-49 months follow-up, 2.7-12.5 % of MW ablated lesions at 5-19 months follow-up and 5.2 % of lesions treated with LITT at 6-month follow-up. Major complications were observed in 4-33 % of patients treated with RF ablation, 0-19 % of patients treated with MW ablation and 0.1-3.5 % of lesions treated with LITT. Although not significantly different, the mean of 1-, 3- and 5-year survival rates for RF-, MW- and laser ablated lesions was (92.6, 44.7, 31.1 %), (79, 38.6, 21 %) and (94.2, 61.5, 29.2 %), respectively. The median survival in these methods was 33.2, 29.5 and 33.7 months, respectively. Thermal ablation may be an appropriate alternative in patients with CRLM who have inoperable liver lesions or have operable lesions as an adjunct to resection. However, further competitive evaluation should clarify the efficacy and priority of these therapies in patients with colorectal cancer liver metastases.

    A microbeam synchrotron X-ray fluorescence (μSRXRF) technique has been used to determine the localization and the relative concentrations of Zn, Cu, Fe and Ca in primary colorectal cancer and secondary colorectal liver metastases. 24 colon and 23 liver samples were examined, all of which were formalin fixed tissues arranged as microarrays of 1.0 mm diameter and 10 μm thickness. The distribution of these metals was compared with light transmission images of adjacent sections that were H and E stained to reveal the location of the cancer cells. Histological details were provided for each sample which enable concentrations of all elements in different tissue types to be compared. In the case of liver, significant differences have been found for all elements when comparing tumour, normal, necrotic, fibrotic, and blood vessel tissues (Kruskal Wallis Test, Pcolon samples (Kruskal Wallis Test, Pcolon tissues. Comparing liver tumour and colon tumour samples, significant differences have been found for all elements (Mann Whitney, Pcolon areas (independent T test, P=0.007 for Zn and Mann Whitney test P<0.0001 for Cu, Fe and Ca). For the blood vessel tissue, the analysis revealed that the difference was only significant for Fe ( P=0.009) from independent T test.

    Full Text Available Gastric cancer is the third leading cause of cancer-related mortality worldwide. Systemic chemotherapy is the main treatment option for advanced gastric cancer when the tumor is inoperable. Despite recent advances in chemotherapeutic agents, the prognosis of unresectable or recurrent gastric cancer remains extremely poor. In Japan, combination therapy including S-1 and cisplatin is the standard first-line treatment for advanced gastric cancer; however, the five-year survival rate remains very low. Lentinan, the backbone of beta-(1,3-glucan with beta-(1,6 branches, an active ingredient purified from Shiitake mushrooms, has been approved as a biological response modifier for the treatment of gastric cancer. This agent has been used in combination with oral fluoropyrimidines to improve the overall survival of gastric cancer patients. A retrospective chart review on 138 metastatic gastric cancer patients receiving chemotherapy was performed in Nagoya Memorial Hospital from 1 September 2010 to 31 August 2015. 12 patients with liver metastases were treated by lentinan in combination with S-1-based chemotherapy. The rate of objective response was 42% (5/12 and the disease control rate was 83% (10/12 in response to chemo-immunotherapy using lentinan, with a median overall survival of 407 days (95% CI: 207–700 days.

    Full Text Available Liver metastases are commonly encountered in patients presenting with metastatic colorectal cancer (mCRC; resection is the treatment of choice. A number of systemic treatment options are currently available for such patients, including the use of 5-fluorouracil-based chemotherapies and oxaliplatin (e.g., FOLFOX in combination with biologic agents that target angiogenesis (e.g., bevacizumab. For patients with progression following first-line treatment, current second-line options include a change in chemotherapy with bevacizumab (for patients who did or did not receive prior bevacizumab or FOLFIRI in combination with aflibercept, a more recently approved antiangiogenesis therapy. Neurotoxicity is a well-established adverse event of oxaliplatin-based therapy. The current case details an mCRC patient with liver metastases who was treated with a capecitabine and oxaliplatin regimen (XELOX, and experienced two episodes of transient cortical blindness possibly related to oxaliplatin. After disease progression, the patient was switched to a regimen of FOLFIRI and aflibercept and did well on this second-line regimen.

    Full Text Available Objective: Cancer represents the second cause of mortality in the world. Saffron as a medicinal plant is known for its anti-cancer and anti-depressant properties. In this randomized double blind clinical trial, the effects of saffron on response to treatment in patients suffering from liver metastasis were evaluated. Materials and Methods: Thirteen patients suffering from liver metastases who referred to Ghaem and Imam Reza hospital, Mashhad, Iran were included in this study and then divided into two different groups. Both groups received chemotherapy regimen. Patients in group one were treated with saffron capsule (50 mg, twice daily during chemotherapy periods whereas patients in group two received placebo. A sum of the longest diameter were calculated and compared for all lesions in IV contrast CT scan before and after the treatment. Results: from 13 patients included in this study, six patients quit and seven continued until the end. In saffron-treated group, two patients showed partial and complete response (50% whereas in placebo group, no response was seen. Also, two deaths in placebo and one in saffron group occurred. Conclusion: This research suggests that saffron might be useful in patients suffering from liver metastasis. However, further investigations with larger sample size are required.

    Neoadjuvant chemotherapy (NACT) prior to liver resection is advantageous for patients with colorectal cancer liver metastases (CLM). Bevacizumab- or cetuximab-based NACT may affect patient outcome and curative resection rate, but comparative studies on differential tumour regression grade (TRG) associated with distinct antibodies-associated regimens are lacking. Ninety-three consecutive patients received NACT plus bevacizumab (n = 46) or cetuximab (n = 47) followed by CLM resection. Pathological response was determined in each resected metastasis as TRG rated from 1 (complete) to 5 (no response). Except for KRAS mutations prevailing in bevacizumab versus cetuximab (57 vs. 21 %, p = 0.001), patients characteristics were well balanced. Median follow-up was 31 months (IQR 17-48). Bevacizumab induced significantly better pathological response rates (TRG1-3: 78 vs. 34 %, p < 0.001) as well as complete responses (TRG1: 13 vs. 0 %, p = 0.012) with respect to cetuximab. Three-year progression-free survival (PFS) and overall survival (OS) were not significantly different in the two cohorts. At multivariable analysis, significant association with pathological response was found for number of resected metastases (p = 0.015) and bevacizumab allocation (p < 0.001), while KRAS mutation showed only a trend. Significant association with poorer PFS and OS was found for low grades of pathological response (p = 0.009 and p < 0.001, respectively), R2 resection or presence of extrahepatic disease (both p < 0.001) and presence of KRAS mutation (p = 0.007 and p < 0.001, respectively). Bevacizumab-based regimens, although influenced by the number of metastases and KRAS status, improve significantly pathological response if compared to cetuximab-based NACT. Possible differential impact among regimens on patient outcome has still to be elucidated.

The aim of this study was to define the optimal management for asymptomatic patients with colorectal cancer and unresectable liver metastases. Patients and methods: Patients receiving elective surgery (n = 17 were compared to patients receiving chemotherapy only (n = 31. Data concerning patients' demographics, location of primary tumor, comorbidities, performance status, Child–Pugh score, extension of liver metastases, size of primary, and other secondary locations were collected. Results: Thirty-day mortality after chemotherapy was lower than that after surgical resection (19.3% versus 29.4%; not significant. In patients with >75% hepatic involvement, mortality at 1 month was higher after receiving surgical treatment than after chemotherapy alone (50% versus 25%. In patients with <75% hepatic involvement, 30-day mortality was similar in both groups (not significant. Thirty-day mortality in patients with Stage T3 was lower in those receiving chemotherapy (16.7% versus 30%; not significant. Overall survival was similar in both groups. The risk of all-cause death after elective surgery (2.1 was significantly higher than in patients receiving chemotherapy only (P = 0.035.

    Metastatic growth and invasion by colon cancer cells in the liver requires the ability of the cancer cells to interact with the new tissue environment. Plasmin(ogen) is activated on cell surfaces by urokinase-type PA (uPA), and is regulated by uPAR and plasminogen activator inhibitor-1 (PAI-1......). To compare the expression patterns of uPA, uPAR and PAI-1 in colon cancer with that in their liver metastases, we analysed matched samples from 14 patients. In all 14 primary colon cancers, we found upregulation of uPAR, uPA mRNA and PAI-1 in primarily stromal cells at the invasive front. In 5 of the 14......, whereas 8 of the remaining 9 showed direct contact between the cancer cells and the liver parenchyma. We conclude that there are 2 distinct patterns of expression of uPAR, uPA and PAI-1 in colon cancer liver metastases and that these correlate closely with 2 morphological growth patterns.

    De novo expression of HLA-G has been demonstrated in colorectal cancer. HLA-G, amongst others, inhibits natural killer cell function, contributing to host immune defense evasion. Another mechanism to escape anti-tumor immunity is loss of HLA class I. Therefore, we determined HLA-G and HLA class I expression on primary colorectal tumors and associated liver metastases, in order to get insight in the metastasizing process regarding escaping anti-tumor immunity. HLA-G expression was evaluated using three mAbs; 4H84, MEM-G/1 and MEM-G/2. In total 81 colorectal cancer patients were evaluated. Formalin-fixed paraffin-embedded tissue sections of primary tumors and associated liver metastases, were immunohistochemically stained. A concordance between expression or loss/downregulation in the primary tumor and associated liver metastasis regarding HLA class I expression was observed in 80% of the cases. In contrast with the hypothesis of escaping NK cell-killing, we demonstrated for each HLA-G detecting mAbs used in this study, that the majority of the primary tumors that positively stained for HLA-G did not express HLA-G in the associated liver metastasis. Furthermore, we revealed the existence of non-specific binding and in addition we found that the different epitopes of HLA-G detected by 4H84, MEM-G/1 and MEM-G/2 mAbs were expressed differentially in colorectal tumor tissues.

    Background The objective of this study was to compare the results of laparoscopic hepatectomy with those of open hepatectomy for colorectal cancer liver metastases (CCLM) using a propensity score matching (PSM) in two university hospital settings. Methods A patient in the laparoscopic approach (LA) surgery group was randomly matched with another patient in the open approach (OA) group using a 1:1 allocated ratio with the nearest estimated propensity score. No patients of the LA group were excluded for the matching. Matching criteria included age, gender, body mass index (BMI), American society anesthesiologists score, potential co-morbidities, hepatopathies, synchronous or metachronous lesions, size and number of CCLM, preoperative chemotherapy, minor or major liver resections. Intraoperative, postoperative data, and survival were compared in both groups. Results From January 2012 to January 2015, a total of 242 hepatectomies were consecutively performed, of which 119 for CCLM, namely 101 in the OA group (84.9%) and 18 in the LA group (15.1%). The conversion rate was 5.6% (n=1). The mortality rate was 1% in the OA group and 0% in the LA group. Prior to PSM, there was a statistically significant difference favorable to the LA group regarding operative time, blood loss, length of hospital stay and the rate of medical complications. After PSM, there was no difference regarding operative time or length of hospital stay. However, there was a trend towards less blood loss (P=0.066) and fewer medical complications (44.4% vs.16.7%, P=0.07). The R0 resection rate was 94.4% (n=17) in the two groups. In addition, there was no difference regarding overall survival (P=0.358) and recurrence-free survival [HR =0.99 (0.1–12.7); P=0.99]. Conclusions Laparoscopic liver resections for CCLM seem to yield short- and long-term results, which are similar to open hepatectomies, and could well be considered an alternative to open surgery and become the gold standard in carefully selected

    2012-12-01

    Full Text Available CONTEXT: Liver metastases are a common event in the clinical outcome of patients with colorectal cancer and account for 2/3 of deaths from this disease. There is considerable controversy among the data in the literature regarding the results of surgical treatment and prognostic factors of survival, and no analysis have been done in a large cohort of patients in Brazil. OBJECTIVES: To characterize the results of surgical treatment of patients with colorectal liver metastases, and to establish prognostic factors of survival in a Brazilian population. METHOD: This was a retrospective study of patients undergoing liver resection for colorectal metastases in a tertiary cancer hospital from 1998 to 2009. We analyzed epidemiologic variables and the clinical characteristics of primary tumors, metastatic disease and its treatment, surgical procedures and follow-up, and survival results. Survival analyzes were done by the Kaplan-Meier method and the log-rank test was applied to determine the influence of variables on overall and disease-free survival. All variables associated with survival with P<0.20 in univariate analysis, were included in multivariate analysis using a Cox proportional hazard regression model. RESULTS: During the period analyzed, 209 procedures were performed on 170 patients. Postope-rative mortality in 90 days was 2.9% and 5-year overall survival was 64.9%. Its independent prognostic factors were the presence of extrahepatic disease at diagnosis of liver metastases, bilateral nodules and the occurrence of major complications after liver surgery. The estimated 5-year disease-free survival was 39.1% and its prognostic factors included R1 resection, extrahepatic disease, bilateral nodules, lymph node involvement in the primary tumor and primary tumors located in the rectum. CONCLUSION: Liver resection for colorectal metastases is safe and effective and the analysis of prognostic factors of survival in a large cohort of Brazilian patients

    A 55-year-old woman underwent low anterior resection for sigmoid colon cancer with multiple bilobar metastases. She then received 23 courses of Leucovorin, fluorouracil, and oxaliplatin (mFOLFOX) plus bevacizumab and 13 courses of Leucovorin, fluorouracil, and irinotecan (FOLFIRI) plus bevacizumab as down staging chemotherapy. A two-stage hepatectomy was planned to avoid the risk of hepatic failure due to radial resection of bilobar metastases. Therefore, a right lobectomy was performed, and curative resection was achieved 54 days after the first hepatectomy. Two-stage hepatectomy as well as a combination of induction chemotherapy and portal vein embolization may have contributed to the improved prognosis of the initially unresectable multiple bilobar liver metastases.

    We previously reported on the safety and efficacy of laparoscopic radiofrequency thermal ablation (RFA) for treating hepatic neuroendocrine metastases. The aim of this study is to report our 5-year RFA experience in the treatment of these challenging group of patients. Of the 222 patients with 803 liver primary and secondary tumors undergoing laparoscopic RFA between January 1996 and August 2001, a total of 34 patients with 234 tumors had neuroendocrine liver metastases. There were 25 men and 9 women with a mean +/- SEM age of 52 +/- 2 years who underwent 42 ablations. Primary tumor types included carcinoid tumor in 18 patients, medullary thyroid cancer in 7, secreting islet cell tumor in 5, and nonsecreting islet cell tumor in 4. There was no mortality, and the morbidity was 5%. The mean hospital stay was 1.1 days. Symptoms were ameliorated in 95%, with significant or complete symptom control in 80% of the patients for a mean of 10+ months (range 6-24 months). All patients were followed for a mean +/- SEM of 1.6 +/- 0.2 years (range 1.0-5.4 years). During this period new liver lesions developed in 28% of patients, new extrahepatic disease in 25%, and local liver recurrence in 13%; existing liver lesions progressed in 13%. Overall 41% of patients showed no progression of their cancer. Nine patients (27%) died. Mean +/- SEM survivals after diagnosis of primary disease, detection of liver metastases, and performance of RFA were 5.5 +/- 0.8 years, 3.0 +/- 0.3 years, and 1.6 +/- 0.2 years, respectively. Sixty-five percent of the patients demonstrated a partial or significant decrease in their tumor markers during follow-up. In conclusion, RFA provides excellent local tumor control with overnight hospitalization and low morbidity in the treatment of liver metastases from neuroendocrine tumors. It is a useful modality in the management of these challenging group of patients.

    Plasma aldosterone levels were measured in 50 patients with confirmed liver metastases from various histologically proved primary tumors. None of these patients had electrolyte abnormalities or history of benign liver disease, congestive heart failure, hypertension, or renal disease. Patients with edema, ascites, or both had significantly greater elevation of plasma aldosterone levels compared to nonedematous patients; these patients also demonstrated a substantial degree of hepatic dysfunction as evidenced by lower serum albumin levels and higher bilirubin and alkaline phosphatase levels. This study provides a rational basis for the use of the specific aldosterone inhibitor spironolactone in the treatment of patients with advanced metastatic liver disease and edematous states.

    Full Text Available Background. Hepatic lymph node involvement is generally considered a contraindication for liver resection performed for colorectal liver metastases. However, some advocate hepatic lymphadenectomy in the presence of macroscopic involvement and others routine lymphadenectomy. The aim of this review is to assess the role of lymphadenectomy in resection of liver metastases from colorectal cancer. Methods. Medline, Embase and Central databases were searched using a formal search strategy. Trials with survival data with a minimum follow-up of 1 year were considered for inclusion. Meta-analysis was performed using Revman. Results. A total of 4230 references were identified. Ten reports of nine studies including 926 patients qualified for the review. The prevalence of nodal metastases after routine lymphadenectomy was 16.3%. The overall 3-year and 5-year survival rates in node-positive patients were 9/151 (11.3% and 2/137 (1.5%, respectively, compared to 3-year and 5-year survival rates of 424/787 (53.9% and 246/767 (32.1% in node-negative patients. The odds ratios for 3-year and 5-year survivals in node positive disease compared to node-negative disease were 0.12 (95% CI 0.06 to 0.24 and 0.08 (95% CI 0.03 to 0.22. There was no randomized controlled trial which assessed the survival benefit of routine or “selective” lymphadenectomy. Conclusion. Currently, there is no evidence of survival benefit for routine or selective lymphadenectomy. Survival rates are low in patients with positive lymph nodes draining the liver irrespective of whether they are detected by routine lymphadenectomy or by macroscopic involvement. Further trials in this patient group are required.

    We describe the case of an 87-year-old woman who presented to Tokyo Kousei Nenkin Hospital because of appetite loss and general fatigue. Multiple liver masses and Borrmann type 2 gastric tumor were detected. A clinical diagnosis of hepatocellular carcinoma and gastric cancer was made based on the patient's high levels of serum alpha-fetoprotein (AFP; 490 200 ng/mL) and protein induced by vitamin K absence or antagonist-II (PIVKA-II, 2284 mAU/mL). The patient's general condition worsened gradually and she died 42 days after admission. Autopsy revealed that the predominant histological structure of the gastric tumor was trabecular or sheet-like, although a tubular structure was also found. Venous invasion was prominent. Immunohistochemically, the tumor tissue was positive for AFP and a few tumor cells were positive for PIVKA-II. The histological appearance and immunohistochemical features of the hepatic tumors resembled that of the gastric tumor. This case was pathologically diagnosed as AFP- and PIVKA-II-producing gastric carcinoma with multiple liver metastases. When tumors are found in the stomach and liver and serum PIVKA-II level is abnormally high, the possibility of PIVKA-II-producing gastric cancer with liver metastasis should be considered, especially when hepatitis virus markers are negative and liver cirrhosis is not present.

    A 70s-year-old man was referred to our hospital because of sigmoid colon cancer. Computed tomography (CT) revealed a large mass in the right lobe of the liver and small masses in Couinaud segments Ⅳ and Ⅵ. We started systemic chemotherapy with mFOLFOX6 and panitumumab. After 6 courses of the treatment, the size and number of the liver metastases was remarkably reduced on CT. We performed a simultaneous laparoscopic resection for the primary tumor and synchronous liver metastases. The postoperative course was uneventful and he had no signs of recurrence 12 months after surgery.

    Docetaxel is the current first-line treatment for castration-resistant prostate cancer (CRPC), following failure to respond to maximal androgen blockade (MAB). Patients who fail to respond to docetaxel may receive cabazitaxel or abiraterone; however, there are no recommendations on which of these two agents should be used first. Here, we present a case of a male patient suffering from CRPC with liver and lymph node metastases, in which abiraterone achieved a partial response, according to RECIST criteria. In the literature, visceral involvement in patients with advanced prostate cancer is an infrequent occurrence; it affects 18-22% of patients. In the pivotal study concerning docetaxel-resistant patients, abiraterone was compared with a placebo and the forest plot for survival demonstrated that patients with visceral involvement have significantly benefited from abiraterone. In the TROPIC trial comparing cabazitaxel with mitoxantrone, the proportion of patients with visceral disease was ∼25% in both arms and there was no difference in overall survival in this subgroup of patients. In our case, we observed a significant activity of abiraterone in lymph node and liver metastases. If confirmed in large studies, this observation may raise concerns over whether to treat patients suffering from CRPC and visceral metasis with chemotherapy or hormone therapy.

    We report a case of brain metastasis from rectal cancer a long time after the initial resection. A 62-year-old woman, diagnosed with lower rectal cancer with multiple synchronous liver and lung metastases, underwent abdominoperineal resection after preoperative radiochemotherapy (40 Gy at the pelvis, using the de Gramont regimen FL therapy: 1 kur). The histological diagnosis was a moderately differentiated adenocarcinoma. Various regimens of chemotherapy for unresectable and metastatic colorectal cancer were administered, and a partial response was obtained; thereby, the metastatic lesions became resectable. The patient underwent partial resection of the liver and lung metastases. Pathological findings confirmed that both the liver and lung lesions were metastases from the rectal cancer. A disease-free period occurred for several months; however, there were recurrences of the lung metastases, so we started another round of chemotherapy. After 8 months, she complained of vertigo and dizziness. A left cerebellar tumor about 3 cm in diameter was revealed by MRI and neurosurgical excision was performed. Pathological findings confirmed a cerebellar metastasis from the rectal cancer. Twenty months after resection of the brain tumor, the patient complained of a severe headache. A brain MRI showed hydrocephalia, and carcinomatous meningitis from rectal cancer was diagnosed by a spinal fluid cytology test. A ventriculo-peritoneal shunt was inserted, but the cerebrospinal pressure did not decreased and she died 20 months after the first surgery. Although brain metastasis from colorectal cancer is rare, the number of patients with brain metastasis is thought to increase in the near future. Chemotherapy for colorectal cancer is effective enough to prolong the survival period even if multiple metastases have occurred. However, after a long survival period with lung metastases such as in our case, there is a high probability of developing brain metastases.

    We attempted to determine whether the combined regimen of radioimmunotherapy (RIT) and antiangiogenic therapy would favorably affect the survival of animals bearing liver metastases of colon cancer cells. Daily antiangiogenic therapy with 2-methoxyestradiol (2-ME), 75 mg/kg, was initiated at 3 days following intrasplenic cell inoculation of LS180 colon cancer cells. RIT with 7 MBq of {sup 131}I-A7, an IgG1 anti-colorectal monoclonal antibody, or {sup 131}I-HPMS-1, an irrelevant IgG1, was conducted at 7 days. Production of vascular endothelial growth factor (VEGF) by LS180 cells was assessed in vitro. All nontreated mice died by 31 days following cell inoculation (n=5). Monotherapy comprising 2-ME treatment resulted in slightly better survival of mice (n=8) (P<0.05). {sup 131}I-A7 RIT displayed a marked therapeutic effect (n=8) (P<0.001); however, all animals eventually died due to metastases by 99 days. The combined regimen of {sup 131}I-A7 RIT and antiangiogenic therapy demonstrated a superior therapeutic effect in comparison to monotherapy consisting of either RIT or antiangiogenic therapy (n=10) (P<0.05); three mice survived the entire 160-day observation period. The combination of antiangiogenic therapy and {sup 131}I-HPMS-1 RIT failed to provide an appreciable benefit (n=5). Treatment with 2-ME decreased VEGF production by LS180 cells in a dose-dependent fashion. In conclusion, a combination regimen comprising RIT and antiangiogenic therapy initiated at the early stage of metastasis would be of great benefit in terms of improvement of the therapeutic efficacy with respect to liver metastases.

    2012-02-01

    Full Text Available Introduction: Colorectal cancer (CRC is the 3rd leading cause of cancer-related death in the U.S. Many patients with CRC develop hepatic metastases as the sole site of metastases. Historical treatment options were limited to resection or conventional radiation therapy. Stereotactic body radiation therapy (SBRT has emerged as a rational treatment approach. This study reviews our experience with SBRT for patients with liver metastases from CRC.Material and Methods: Fourteen histologically confirmed hepatic CRC metastases in 11 consecutive patients were identified between November, 2004 and June, 2009 at Georgetown University. All patients underwent CT-based treatment planning; a few also had MRI or PET/CT. All patients had fiducial markers placed under CT guidance and were treated using the CyberKnife system. Treatment response and toxicities were examined; survival and local control were evaluated.Results: Most patients were treated to a single hepatic lesion (n=8, with a few treated to 2 lesions (n=3. Median treatment volume was 99.7 cm3, and lesions were treated to a median BED10 of 49.7 Gy (range: 28 – 100.8 Gy. Median follow-up was 21 months; median survival was 16.1 months, with 2-year actuarial survival of 25.7%. One-year local control was 72%. Among patients with post-treatment imaging, 8 had stable disease (80% and 2 had progressive disease (20% at first follow-up. The most common grade 1-2 acute toxicities included nausea and alterations in liver function tests; there was one grade 3 toxicity (elevated bilirubin, and no grade 4-5 toxicities.Discussion: SBRT is safe and feasible for the treatment of limited hepatic metastases from CRC. Our results compare favorably with outcomes from previous studies of SBRT. Further studies are needed to better define patient eligibility, study the role of combined modality treatment, optimize treatment parameters, and characterize quality of life after treatment.

    2012-01-01

    Full Text Available Introduction. Simultaneous resection of primary colorectal carcinoma (CRC and synchronous liver metastases (SLMs is subject of debate with respect to morbidity in comparison to staged resection. The aim of this study was to evaluate our initial experience with this approach. Methods. Five patients with primary CRC and a clinical diagnosis of SLM underwent combined laparoscopic colorectal and liver surgery. Patient and tumor characteristics, operative variables, and postoperative outcomes were evaluated retrospectively. Results. The primary tumor was located in the colon in two patients and in the rectum in three patients. The SLM was solitary in four patients and multiple in the remaining patient. Surgical approach was total laparoscopic (2 patients or hand-assisted laparoscopic (3 patients. The midline umbilical or transverse suprapubic incision created for the hand port and/or extraction of the specimen varied between 5 and 10 cm. Median operation time was 303 (range 151–384 minutes with a total blood loss of 700 (range 200–850 mL. Postoperative hospital stay was 5, 5, 9, 14, and 30 days. An R0 resection was achieved in all patients. Conclusions. From this initial single-center experience, simultaneous laparoscopic colorectal and liver resection appears to be feasible in selected patients with CRC and SLM, with satisfying short-term results.

    Colorectal cancer liver metastases (CLM) treatment is very important given the high incidence of colorectal cancer with liver metastases, which are primarily treated by surgical resection. Transformational therapy such as systemic chemotherapy, hepatic arterial infusion (HAI), portal vein embolization (PVE), ablation therapy, and targeted therapy, should be applied to CLM patients who are unable to undergo immediate surgery to improve patients’ survival and quality of life.

    Purpose. Our study analyses clinical trials and evaluates the efficacy of adding cetuximab in systematic chemotherapy for unresectable colorectal cancer liver-confined metastases patients. Materials and Methods. Search EMBASE, PubMed, and the Cochrane Central Register of Controlled Trials for RCTs comparing chemotherapy plus cetuximab with chemotherapy alone for KRAS wild type patients with colorectal cancer liver metastases (CRLMs). We calculated the relative risks (RRs) with 95% confidence interval and performed meta-analysis of hazard ratios (HRs) for the R0 resection rate, the overall response rate (ORR), the progression-free survival (PFS) and overall survival (OS). Results. 1173 articles were retrieved and 4 RCTs were available for our study. The four studies involved 504 KRAS wild type patients with CRLMs. The addition of cetuximab significantly improved all the 4 outcomes: the R0 resection rate (RR 2.03, p = 0.004), the ORR (RR 1.76, p < 0.00001), PFS (HR 0.63, p < 0.0001), and also OS (HR 0.74, p = 0.04); the last outcome is quite different from the conclusion published before. Conclusions. Although the number of patients analysed was limited, we found that the addition of cetuximab significantly improves the outcomes in KRAS wild type patients with unresectable colorectal cancer liver-confined metastases. Cetuximab combined with systematic chemotherapy perhaps suggests a promising choice for KRAS wild type patients with unresectable liver metastases. PMID:28167959

    AIM: To assess a protocol for treating patients with multiple synchronous colonic cancer liver metastases, which are unresectable in one stage. METHODS: Patients enrolled in the "liver first" protocol presented with colon-only(not rectal) cancer and multiple synchronous hepatic metastases(type Ⅱ or Ⅲ). All patients showed good performance status(ECOG PS 0-1) and were treated with curative intent. Complete oncologic staging including positron emission tomography-computed tomography was performed in order to rule out extrahepatic disease. If bowel obstruction was imminent, an intraluminal colonic stent was placed endoscopically. Subsequently, all patients received standardised neo-adjuvant chemotherapy, that is, FOLFOX or XELOX regimens combined with an antiangiogenic agent(bevacizumab or cetuximab). Provided that a response to chemotherapy was observed, patients underwent either one or two hepatectomies with or without portal vein embolization followed by the indicated colectomy. Further chemotherapy was administered after each procedure. Re-staging was performed after each chemotherapeutic treatment. Disease progression at any stage resulted in discontinuation of the protocol and conversion to palliative disease management.RESULTS: Prospectively recorded data from 11 consecutive patients(8 men) were analysed for this study. Their mean age at the time of their first assessment was 65.7(SD ± 15.3) years. Six(54.6%) patients presented with type Ⅲ metastatic disease. The minimum and maximum follow-up periods were 7.3 and 39.6 mo, respectively. The mean overall survival of all patients was 16.5(95%CI: 10.0-23.2) mo. A colonic stent had to be placed in 5(45.5%) patients due to the onset of an intraluminal obstruction. Four(36.4%) patients succeeded in completing all planned surgical operations. Their mean overall survival was 27.2(95%CI: 15.1-39.3) mo and the mean disease-free survival was 7.7(95%CI: 3.0-12.5) mo. Patients, who were obliged to shift to palliative

    Full Text Available Purpose. We sought to evaluate our experience using yttrium-90 (90Y resin microsphere hepatic radioembolization as salvage therapy for liver-dominant metastatic colorectal cancer (mCRC. Methods. A retrospective review of consecutive patients with unresectable mCRC who were treated with 90Y after failing first and second line systemic chemotherapy. Demographics, treatment dose, biochemical and radiographic response, toxicities, and survival were examined. Results. Fifty-one patients underwent 90Y treatments of which 69% were male. All patients had previously undergone extensive chemotherapy, 31% had undergone previous liver-directed therapy and 24% had a prior liver resection. Using RECIST criteria, either stable disease or a partial response was seen in 77% of patients. Overall median survival from the time of first 90Y treatment was 10.2 months (95% CI = 7.5–13.0. The absence of extrahepatic disease at the time of treatment with 90Y was associated with an improved survival, median survival of 17.0 months (95% CI = 6.4–27.6, compared to those with extrahepatic disease at the time of treatment with 90Y, 6.7 months (95% CI = 2.7–10.6 Conclusion: 90Y therapy is a safe locoregional therapy that provides an important therapeutic option to patients who have failed first and second line chemotherapy and have adequate liver function and performance status.

    Purpose: To evaluate safety, feasibility and overall survival rates for transarterial chemoembolization (TACE) alone or combined with MR-guided laser-induced-thermotherapy (LITT) in liver metastases of non-colorectal and non-breast cancer origin. Methods and materials: Included were patients with unresectable non-colorectal non-breast cancer liver metastases with progression under systemic chemotherapy. Excluded were patients with Karnofsky score ≤70, respiratory, renal and cardiovascular failure, and general TACE contraindications. TACE using Mitomycin alone, Mitomycin–Gemcitabine or Mitomycin–Gemcitabine–Cisplatin was performed to all patients. After TACE 146 metastases were ablated with MR-guided LITT. To be eligible for LITT metastases should be <5 cm in size and ≤5 in number. Tumor response was evaluated using MRI according to RECIST. Survival was evaluated using Kaplan–Meier analysis. Results: A total of 110 patients (mean age 59.2 years) with 371 metastases received TACE (mean 5.4 sessions/patient, n = 110) with 76 (69%) receiving LITT (mean 1.6 session/patient) afterwards. TACE resulted in a mean decrease of mean maximum diameter of 52% ± 26.6 and volume change of −68.5% ± 22.9 in the 25 patients (23%) with partial response. Stable disease (n = 59, 54%). Progressive disease (n = 26, 23%). The RECIST outcome after LITT showed complete response (n = 13, 17%), partial response (n = 1, 1%), stable situation (n = 41, 54%) and progressive disease (n = 21, 28%). The mean time to progression (TTP) was 8.6 months. Median survival of all patients was 21.1 months. Conclusion: TACE with different protocols alone and in combination with LITT is a feasible palliative treatment option resulting in a median survival of 21.1 months for unresectable liver metastases of non-colorectal and non-breast cancer origin.

    MicroRNAs are small non-coding RNAs with a length of 18–25 nucleotides. They can regulate tumor invasion and metastasis by changing the expression and translation of their target mRNAs. Their expression is substantially altered in colorectal cancer cells as well as in the adjacent tumor-associated stroma. Both of these compartments have a mutual influence on tumor progression. In the development of metastases, cancer cells initially interact with the host tissue. Therefore, compartment-specific expression signatures of these three locations—tumor, associated stroma, and host tissue—can provide new insights into the complex tumor biology of colorectal cancer. Frozen tissue samples of colorectal liver (n = 25) and lung metastases (n = 24) were laser microdissected to separate tumor cells and the adjacent tumor-associated stroma cells. Additionally, normal lung and liver tissue was collected from the same patients. We performed a microarray analysis in four randomly selected liver metastases and four randomly selected lung metastases, analyzing a total of 939 human miRNAs. miRNAs with a significant change >2-fold between the tumor, tumor stroma, and host tissue were analyzed in all samples using RT-qPCR (11 miRNAs) and correlated with the clinical data. We found a differential expression of several miRNAs between the tumor, the tumor-associated stroma, and the host tissue compartment. When comparing liver and lung metastases, miR-194 showed a 1.5-fold; miR-125, miR-127, and miR-192 showed a 2.5-fold; miR-19 and miR-215 a 3-fold; miR-145, miR-199-3, and miR-429 a 5-fold; miR-21 a 7-fold; and, finally, miR-199-5 a 12.5-fold downregulation in liver metastases compared to lung metastases. Furthermore miR-19, miR-125, miR-127, miR-192, miR-194, miR-199-5, and miR-215 showed a significant upregulation in the normal liver tissue compared to the normal lung tissue. Univariate analysis identified an association of poor survival with the expression of miR-125 (p = 0

    We report a case of pseudocirrhosis arising in the setting of regression of liver metastases from pancreatic cancer. A 55-year-old asymptomatic woman presented to our clinic with newly diagnosed metastatic pancreatic cancer with extensive liver metastases. She underwent systemic chemotherapy with gemcitabine and oxaliplatin (GEMOX). After 8 cycles of therapy, she had a remarkable response to the therapy evidenced by decline of carcinoembryonic antigen (CEA) and CA19 by > 50% and nearly complete resolution of hepatic metastases in computed tomography (CT) scan. Shortly after, she developed increasing bilateral ankle edema and ascites, associated with dyspnea, progressive weight gain, and declining performance status. Gemcitabine and oxaliplatin were discontinued as other causes of her symptoms such as congestive heart disease or venous thrombosis were ruled out. CT scan 6 mo after the initiation of GEMOX revealed worsening ascites with a stable pancreatic mass. However, it also revealed a lobular hepatic contour, segmental atrophy, and capsular retraction mimicking the appearance of cirrhosis. She was managed with aggressive diuresis and albumin infusions which eventually resulted in a resolution of the above-mentioned symptoms as well as complete resolution of pseudocirrhotic appearance of the liver and ascites in CT scan. This case demonstrates that pancreatic cancer patients can develop pseudocirrhosis. Clinicians and radiologist should be well aware of this entity as early recognition and management can lead to a near complete recovery of liver function and much improved quality of life as illustrated in this case.

    We describe the case of a 78-year-old man presenting with abdominal pain and a weight loss of 5 kg over 2 months. Colonoscopy and abdominal CT suggested colon cancer of hepatic flexure. F-FDG PET/CT scan showed moderate FDG uptake lesion at the hepatic flexure colon and multiple foci of FDG accumulation in the liver. These were considered as colon cancer with multiple hepatic metastases. However, the pathologic finding of colonoscopic biopsy and CT-guided liver biopsy showed only eosinophilic infiltration and no evidence of malignancy.

    Surgical resection offers the best opportunity for survival in patients with colorectal cancer metastatic to the liver, with five-year survival rates up to 58% in selected cases. However, only a minority are resectable at the time of diagnosis. Continuous research in this field aims at increasing the percentage of patients eligible for resection, refining the indications and contraindications for surgery , and improving overall survival. The use of surgical innovations, such as staged resection, portal vein embolization, and repeat resection has allowed higher resection rates in patients with bilobar disease. The use of neoadjuvant chemotherapy allows up to 38% of patients previously considered unresectable to be significantly downstaged and eligible for hepatic resection. Ablative techniques have gained wide acceptance as an adjunct to surgical resection and in the management of patients who are not surgical candidates. Curent management of colorectal liver metastases requires a multidisciplinary approach, which should be individu alized in each case.

  12. Development and Preclinical Application of an Immunocompetent Transplant Model of Basal Breast Cancer with Lung, Liver and Brain Metastases.

    Directory of Open Access Journals (Sweden)

    Olga Aprelikova

    Full Text Available Triple negative breast cancer (TNBC is an aggressive subtype of breast cancer that is associated with a poor prognosis and for which no targeted therapies currently exist. In order to improve preclinical testing for TNBC that relies primarily on using human xenografts in immunodeficient mice, we have developed a novel immunocompetent syngeneic murine tumor transplant model for basal-like triple-negative breast cancer. The C3(1/SV40-T/t-antigen (C3(1/Tag mouse mammary tumor model in the FVB/N background shares important similarities with human basal-like TNBC. However, these tumors or derived cell lines are rejected when transplanted into wt FVB/N mice, likely due to the expression of SV40 T-antigen. We have developed a sub-line of mice (designated REAR mice that carry only one copy of the C3(1/Tag-antigen transgene resulting from a spontaneous transgene rearrangement in the original founder line. Unlike the original C3(1/Tag mice, REAR mice do not develop mammary tumors or other phenotypes observed in the original C3(1/Tag transgenic mice. REAR mice are more immunologically tolerant to SV40 T-antigen driven tumors and cell lines in an FVB/N background (including prostate tumors from TRAMP mice, but are otherwise immunologically intact. This transplant model system offers the ability to synchronously implant the C3(1/Tag tumor-derived M6 cell line or individual C3(1/Tag tumors from various stages of tumor development into the mammary fat pads or tail veins of REAR mice. C3(1/Tag tumors or M6 cells implanted into the mammary fat pads spontaneously metastasize at a high frequency to the lung and liver. M6 cells injected by tail vein can form brain metastases. We demonstrate that irradiated M6 tumor cells or the same cells expressing GM-CSF can act as a vaccine to retard tumor growth of implanted tumor cells in the REAR model. Preclinical studies performed in animals with an intact immune system should more authentically replicate treatment

    OBJECTIVES: Changes, over the last 20 years, in the diagnostic procedures and treatment of primary liver cancer (PLC) and liver metastases of unknown origin (LMUO) may have affected the clinical course of both cancers. Few longitudinal studies examined this issue. In a population-based setting, we...... studied changes in the incidence and prognosis of PLC and LMUO over time. METHODS: Between 1985 and 2004, we identified 2675 patients with PLC and LMUO in three Danish counties, with a population of 1.4 million. We computed the standardized incidence rate (SIR), ratio of PLC to LMUO diagnoses, median...... survival, and estimated mortality rate ratio adjusted for age, sex, and comorbidity. RESULTS: The SIR of PLC increased from 3.2 in 1985 to 5.0 in 2003, and the SIR of LMUO increased from 3.7 to 6.4. No increase was noted in the PLC-to-LMUO ratio over time (P=0.1 for trend).

    2012-01-01

    Liver metastases synchronously or metachronously occur in approximately 50% of colorectal cancer patients. Multimodality comprehensive treatment is the best therapeutic strategy for these patients. However, the optimal pattern of multimodality therapy is still controversial, and it raises several significant concerns. Liver resection is the most important treatment for colorectal liver metastases. The definition of resectability has shifted to focus on the completion of R0 resection and normal liver function maintenance. The role of neoadjuvant and adjuvant chemotherapy still needs to be clarified. The management of either progression or complete remission during neoadjuvant chemotherapy is challenging. The optimal sequencing of surgery and chemotherapy in synchronous colorectal liver metastases patients is still unclear. Conversional chemotherapy, portal vein embolization, two-stage resection, and tumor ablation are effective approaches to improve resectability for initially unresectable patients. Several technical issues and concerns related to these methods need to be further explored. For patients with definitely unresectable liver disease, the necessity of resecting the primary tumor is still debatable, and evaluating and predicting the efficacy of targeted therapy deserve further investigation. This review discusses different patterns and important concerns of multidisciplinary treatment of colorectal liver metastases.

    This study was designed to evaluate the relationship between the minimal margin size and local tumor progression (LTP) following CT-guided radiofrequency ablation (RFA) of colorectal cancer liver metastases (CLM). An institutional review board-approved, HIPPA-compliant review identified 73 patients with 94 previously untreated CLM that underwent RFA between March 2003 and May 2010, resulting in an ablation zone completely covering the tumor 4-8 weeks after RFA dynamic CT. Comparing the pre- with the post-RFA CT, the minimal margin size was categorized to 0, 1-5, 6-10, and 11-15 mm. Follow-up included CT every 2-4 months. Kaplan-Meier methodology and Cox regression analysis were used to evaluate the effect of the minimal margin size, tumor location, size, and proximity to a vessel on LTP. Forty-five of 94 (47.9 %) CLM progressed locally. Median LTP-free survival (LPFS) was 16 months. Two-year LPFS rates for ablated CLM with minimal margin of 0, 1-5 mm, 6-10 mm, 11-15 mm were 26, 46, 74, and 80 % (p < 0.011). Minimal margin (p = 0.002) and tumor size (p = 0.028) were independent risk factors for LTP. The risk for LTP decreased by 46 % for each 5-mm increase in minimal margin size, whereas each additional 5-mm increase in tumor size increased the risk of LTP by 22 %. An ablation zone with a minimal margin uniformly larger than 5 mm 4-8 weeks postablation CT is associated with the best local tumor control.

    Vincenza Granata

    Full Text Available To assess the feasibility and effectiveness of quantitative intravoxel incoherent motion (IVIM of Diffusion-weighted imaging (DWI in the assessment of liver metastases treated with targeted chemotherapy agents.12 patients with unresectable liver metastases from colorectal cancer were enrolled and received neoadjuvant FOLFIRI (5-fluorouracil, leucovorin, irinotecan plus bevacizumab therapy. DWI was performed for 36 metastases at baseline and after 14 days from starting the treatment. In addition to the basic IVIM metrics, the product between pseudo-diffusivity and perfusion fraction was considered as a descriptor roughly analogous to the flow. Median diffusion parameters of Region of Interest (ROI were used as representative values for each lesion. Normalized parameters in comparison with the median value of spleen were also collected. The percentual change of the diffusion parameters was calculated. The response to chemotherapy was evaluated according the Response Evaluation Criteria in Solid Tumors (RECIST as calculated on whole-body CT scan obtained three months after treatment. Mann Whitney test and Receiver operating characteristic (ROC analysis were performed.24 lesions were categorized as responding and 12 as not responding. There was no statistically significant difference among absolute and normalized diffusion parameters between the pretreatment and the post-treatment findings. Instead, the perfusion fraction (fp values showed a statistical difference between responder and non-responder lesions: sensitivity and specificity of fp variation was 62% and 93%, respectively.IVIM parameters represent a valuable tool in the evaluation of the anti-angiogenic therapy in patients with liver metastases from colorectal cancer. A percentage change of fp represents the most effective DWI marker in the assessment of tumor response.

    Nassour, Ibrahim; Polanco, Patricio M

    2016-04-01

    Minimally invasive surgery has been cautiously introduced in surgical oncology over the last two decades due to a concern of compromised oncological outcomes. Recently, it has been adopted in liver surgery for colorectal metastases. Colorectal cancer is a major cause of cancer-related death in the USA. In addition, liver metastasis is the most common site of distant disease and its resection improves survival. While open resection was the standard of care, laparoscopic liver surgery has become the standard of care for minor liver resections. Laparoscopic liver surgery provides equivalent oncological outcomes with better perioperative results compared to open liver surgery. Robotic liver surgery has been introduced as it is believed to overcome some of the limitations of laparoscopy. Finally, laparoscopic radio-frequency ablation and microwave coagulation can be used as adjuncts in minimally invasive surgery to complement or replace surgical resection when not possible.

    1984-07-01

    One hundred fifty-seven consecutive patients with small cell lung cancer seen at the National Cancer Institute over a four-year period underwent a series of pretherapy liver staging procedures to determine optimal means of detection and prognostic implications of hepatic metastases. Liver evaluation included physical examination, liver function tests, and liver scan (radionuclide or computerized tomography (CT)), as well as percutaneous and/or peritoneoscopy-directed liver biopsy when possible (74%). Liver metastases were detected in 26% of patients. Peritoneoscopy was the most sensitive method of liver evaluation and increased the detection of liver metastases when done in a sequential fashion after percutaneous liver biopsy from 18 to a total of 27 patients. Of the noninvasive procedures, radionuclide and CT liver scan were the most accurate concurring with liver biopsy in 87% of patients but permitting correct discrimination of stage in excess of 96% of patients. The accuracy of this noninvasive procedure was enhanced by an algorithm combining the results of radionuclide liver scan with liver function tests to detect patients with high or low likelihood of liver involvement. The survival and response of patients with liver metastases was significantly worse than those without such metastases with no three-year disease-free survivors among patients with liver metastases.

    We report a case of notably increased plasma levels of microRNA (miR)-21, miR-25, miR-103 and miR-151 in a pancreatic cancer patient with liver and pleural metastases. CD45-coated immunomagnetic beads detected an enrichment of malignant cancer cells in the pleural fluid, and CD133(+)CK18(+) cancer cells were identified. Using computer tomography (CT) combined with cancer cells stained in the pleural fluid, a previously healthy 60-year-old male was diagnosed with pancreatic cancer with multiple liver tumor metastases. Cancer antigen 19-9 (CA19-9), alkaline phosphatase (ALP) and γ-glutamate-transpeptidase (γ-GT) were notably increased in the serum, and carcinoembryonic antigen (CEA) was increased in the pleural fluid. The patient succumbed to the disease three months following standard chemotherapy. The increased levels of plasma miR-21, miR-25, miR-103 and miR-151, as well as the identification of CD133(+)CK18(+) cells in the pleural fluid of a pancreatic cancer patient with liver metastases, may regulate the molecular mechanisms involved in chemoresistance. The patient was insensitive to chemotherapy and succumbed 3 months later. Full elucidation of the molecular and pathological features of pancreatic cancer may be a novel strategy for diagnosis and tailored therapy.

    2015-11-01

    The different biological features of the various major entities of thyroid cancer, e.g. papillary, follicular, poorly differentiated, anaplastic and medullary, depend to a large extent on their different metastatic spread. Papillary thyroid cancer (PTC) has a propensity for cervical lymphatic spread that occurs in 20-50 % of patients whereas distant metastasis occurs in thyroid cancer (FTC) has a marked propensity for vascular but not lymphatic invasion and 10-20 % of FTC develop distant metastases. At the time of diagnosis approximately one third of medullary thyroid cancer (MTC) cases show lymph node metastases, in 10-15 % distant metastases and 25 % develop metastases during the course of the disease. Poorly differentiated (PDTC) and anaplastic thyroid cancer (ATC) spread via both lymphatic and vascular invasion. Thus distant metastases are relatively uncommon in DTC and when they occur, long-term stable disease is the typical clinical course. The major sites of distant metastases are the lungs and bone. Metastases to the brain, breasts, liver, kidneys, muscle and skin are relatively rare or even rare. The thyroid gland itself can be a site of metastases from a variety of other tumors. In autopsy series of patients with disseminated cancer disease, metastases to the thyroid gland were found in up to 10 % of cases. Metastases from other primary tumors to the thyroid gland have been reported in 1.4-3 % of patients who have surgery for suspected cancer of the thyroid gland. The most common primary cancers that metastasize to the thyroid gland are renal cell (48.1 %), colorectal (10.4 %), lung (8.3 %) and breast cancer (7.8 %) and surprisingly often sarcomas (4.0 %).

    Full Text Available CONTEXT: The diagnosis of primary melanoma is easily confirmed after histological analysis of the lesion, whereas it is rarely diagnosed when the patient even has distant metastases. DESIGN: Case report CASE REPORT: Malignant melanoma is responsible for about 1% of all deaths caused by cancer in the USA and only 3% of all malig-nant skin diseases. Malignant melanoma is a rare disease, although it corresponds to 65% of all deaths caused by skin cancer. The liver and spleen are rarely the first sites of melanoma metastases. This paper reports on the clinical picture of a patient with fatal malignant melanoma and hepatic and spleen metastases. As this was an un-usual presentation, the melanoma diagnosis could only be made after pathological analysis of the skin and hepatic lesions.

  6. Therapeutic potential of octreotide in the treatment of liver metastases.

    Science.gov (United States)

    Davies, N; Cooke, T G; Jenkins, S A

    1996-01-01

    Octreotide is a synthetic analogue of somatostatin that has clear inhibitory effects on the growth of many animal and human cell lines, including colorectal cell lines both in vitro and in vivo. Colorectal cancer metastatic to the liver is clinically important, both in terms of the number of patients affected and the lack of any effective treatment for the majority of patients. Octreotide inhibits the growth of colorectal liver tumour in a number of experimental models and, in at least three tumour types, inhibits the growth of established micro-metastases. The precise mechanism of action is not known. However, the drug is likely to be most beneficial in the treatment of liver metastases when the tumour burden is relatively small. The available evidence, although experimental, suggests that octreotide may also have a beneficial effect on the development of liver metastases when used as an adjuvant to surgery in colorectal cancer and this area warrants urgent clinical investigation. The cytotoxics which are currently used as an adjuvant to surgery for colorectal cancer have unpleasant side effects which can be life-threatening. There will also be a proportion of patients who have undergone a truly curative resection of their tumour and will thus be treated unnecessarily. The potential benefits of octreotide in the adjuvant setting, although promising, remain speculative, but octreotide has an acceptably low incidence of side effects and can be administered safely for a prolonged period of time.

    As colorectal cancer and colorectal liver metastases become a serious public health problem, new treatment modalities are needed in order to achieve better results. In the last decade there has been very important progress in oncology, with new and more effective chemotherapeutic agents administered alone or in combination improving the resectability rate in up to 40% of patients with colorectal liver metastases. Advances in interventional radiology, in particular, with the use of portal vein embolization and radiofrequency thermal ablation are new strategies allowing major liver resections and treatment of small liver metastases or early recurrences. Surgery, however, remains the gold standard strategy with intention to treat. In this review article we will describe the advanced role of surgery in the multidisciplinary approach to colorectal liver metastases, and the clinical problems the liver surgeon has to deal with, such as the resectability of the metastases, the presence of bilobar liver lesions and extrahepatic disease, the impact of chemotherapy in already resectable liver metastases, the problem of vanishing metastases after chemotherapy and the dilemma of staged or combined liver and colon operations and which organ first in the clinical scenario of synchronous colorectal liver metastases.

    Primary liver cancer is the fifth most common malignancy in men and the eighth in women worldwide. The liver is also the second most common site for metastatic spread of cancer. To assist in the diagnosis of these liver lesions non-invasive advanced imaging techniques are desirable. Magnetic resonance (MR) is commonly used to identify anatomical lesions, but it is a very versatile technique and also can provide specific information on tumor pathophysiology and metabolism,in particular with the application of MR spectroscopy (MRS). This may include data on the type, grade and stage of tumors, and thus assist in further management of the disease. The purpose of this review is to summarize and discuss the available literature on proton, phosphorus and carbon-13-MRS as performed on primary liver tumors and metastases, with human applications as the main perspective. Upcoming MRS approaches with potential applications to liver tumors are also included. Since knowledge of some technical background is indispensable to understand the results, a basic introduction of MRS and some technical issues of MRS as applied to tumors and metastases in the liver are described as well. In vivo MR spectroscopy of tumors in a metabolically active organ such as the liver has been demonstrated to provide important information on tumor metabolism, but it also is challenging as compared to applications on some other tissues, in particular in humans, mostly because of its abdominal location where movement may be a disturbing factor.

    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.

    A 75-year-old man was admitted to our hospital with a diagnosis of liver metastases from colon cancer. He underwent right hemicolectomy for cecal cancer eight years ago, and had a metastatic liver tumor in segment 8 (S8),which was surgically resected about 4 years after the initial operation. Histopathological examination of the resected specimens from both operations revealed a welldifferentiated adenocarcinoma with mucinous carcinoma. Four months after the second operation, computed tomography demonstrated a low-density lesion at the cutsurface of the remnant liver. Although it was considered to be a postoperative collection of inflammatory fluid, it formed a cystic configuration and increased in size to approximately 5 cm in diameter. With a tentative diagnosis of a recurrence of metastatic cancer, partial hepatectomy of S8 was performed. Histological examination of the resected specimens also revealed mucinous adenocarci noma, which had invaded into the biliary ducts, replacing and extending along its epithelium. Immunohistochemically, the tumor cells were positive for cytokeratin (CK) 20, but negative for CK7. Therefore, the tumor was diagnosed as a metastatic adenocarcinoma from colonic cancer.

    Pancreatic neuroendocrine tumor(P-NET) is rare and slow-growing. Current classifications predict its progno-sis and postoperative recurrence. Curative resection is ideal, although often difficult, because over 80% of pa-tients have unresectable multiple liver metastases and extrahepatic metastasis. Aggressive surgery for liver metastases is important to improve survival. Aggressive or cytoreductive surgery for liver metastases is indi-cated to reduce hormone levels and improve symptoms and prognosis. Liver transplantation was originally con-ceived as an ideal therapy for unresectable liver metas-tases. Unfortunately, there is no clear consensus on the role and timing of surgery for primary tumor and liver metastases. Surgeons still face questions in deciding the best surgical scenario in patients with P-NET with unresectable liver metastases.

    Objective: To compare the diagnostic value of multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) in the preoperative detection of colorectal liver metastases in diffuse fatty infiltration of the liver, associated with neoadjuvant chemotherapy. Materials and methods: Twenty preoperative tri-phasic MDCT (4-64-row, Siemens) and dynamic contrast-enhanced MRI (1.5 T or 3.0 T, Siemens) examinations of patients with colorectal cancer and liver metastases in diffuse steatosis were retrospectively evaluated. All patients underwent surgical resection for liver metastases (time interval 1-60 days). The amount of fatty infiltration of the liver was determined histopathologically by semi-quantitative percent-wise estimation and ranged from 25 to 75%. Results: Overall, 51 metastases were found by histopathology of the resected liver segments/lobes. The size of the metastases ranged from 0.4 to 13 cm, with 18 (35%) being up to 1 cm in diameter. In the overall rating, MDCT detected 33/51 lesions (65%), and MRI 45/51 (88%). For lesions up to 1 cm, MDCT detected only 2/18 (11%) and MRI 12/18 (66%). One false positive lesion was detected by MDCT. Statistical analysis showed that MRI is markedly superior to MDCT, with a statistically significant difference (p < .001), particularly for the detection of small lesions ({<=}1 cm; p < .004). There was no significant difference between the two modalities in the detection of lesions > 1 cm. Conclusion: For the detection of colorectal liver metastases after neoadjuvant chemotherapy and consecutive diffuse fatty infiltration of the liver, MRI is superior to MDCT, especially for the detection of small lesions.

    Radionuclide imaging has been demonstrated to be feasible to monitor transgene expression in vivo. We hypothesized that a potential application of this technique is to non-invasively detect in deep tissue, such as cancer cells metastatic to the liver, a specific molecular response following systemic drug treatment. Utilizing human colon adenocarcinoma cells derived from a patient's liver lesion we first developed a nude rat xenograft model for colorectal cancer metastatic to the liver. Expression of a dihydrofolate reductase-herpes simplex virus 1 thymidine kinase fusion (DHFR-HSV1 TK) transgene in the hepatic tumors was monitored in individual animals using the tracer [{sup 124}I]2'-fluoro-2'-deoxy-5-iodouracil-{beta}-d-arabinofuranoside (FIAU) and a small animal micro positron emission tomograph (microPET), while groups of rats were imaged using the tracer [{sup 131}I]FIAU and a clinical gamma camera. Growth of the human metastatic colorectal cancer cells in the rat liver was detected using magnetic resonance imaging and confirmed by surgical inspection. Single as well as multiple lesions of different sizes and sites were observed in the liver of the animals. Next, using a subset of rats bearing hepatic tumors, which were retrovirally bulk transduced to express the DHFR-HSV1 TK transgene, we imaged the fusion protein expression in the hepatic tumor of living rats using the tracer [{sup 124}I]FIAU and a microPET. The observed deep tissue signals were highly specific for the tumors expressing the DHFR-HSV1 TK fusion protein compared with parental untransduced tumors and other tissues as determined by gamma counting of tissue samples. A subsequent study used the tracer [{sup 131}I]FIAU and a gamma camera to monitor two groups of transduced hepatic tumor-bearing rats. Prior to imaging, one group was treated with trimetrexate to exploit DHFR-mediated upregulation of the fusion gene product. Imaging in the living animal as well as subsequent gamma

    We report here that polyethylene glycol (PEG) linked to near infrared dyes conjugated to chimeric mouse-human anti-carcinoembryonic antigen (CEA) antibody greatly improves imaging of liver metastases in a nude mouse model of colon-cancer experimental metastases. PEGylated and non-PEGylated DyLight 650 and 750 dyes were conjugated to the chimeric anti-CEA antibody. The dyes were initially injected intravenously into nude mice without tumors. Tissue biodistribution was determined by tissue sonication and analyzing tissue dye concentration profiles over time. PEGylated dyes had significantly lower accumulation in the liver (p = 0.03 for the 650 dyes; p = 0.002 for the 750 dyes) compared to non-PEGylated dyes. In an experimental liver metastasis model of HT-29 colon cancer, PEGylated dyes conjugated to the anti-CEA antibody showed good labeling of metastatic tumors with high contrast between normal and malignant tissue which was not possible with the non-PEGylated dyes since there was so much non-specific accumulation in the liver. PEGylation of the DyLight 650 and 750 NIR dyes significantly altered tissue biodistribution, allowing brighter tissue labeling, decreased accumulation in normal organs, particularly the liver. This enabled high fidelity and high contrast imaging of liver metastases.

    Median survival from liver metastases secondary to breast cancer is only a few months, with very rare 5-year survival. This study reviewed 145 patients with liver metastases from breast cancer to determine factors that may influence survival. Data were analysed using Kaplan-Meier survival curves, univariate and multivariate analysis. Median survival was 4.23 months (range 0.16-51), with a 27.6% 1-year survival. Factors that significantly predicted a poor prognosis on univariate analysis included symptomatic liver disease, deranged liver function tests, the presence of ascites, histological grade 3 disease at primary presentation, advanced age, oestrogen receptor (ER) negative tumours, carcinoembryonic antigen of over 1000 ng ml(-1) and multiple vs single liver metastases. Response to treatment was also a significant predictor of survival with patients responding to chemo- or endocrine therapy surviving for a median of 13 and 13.9 months, respectively. Multivariate analysis of pretreatment variables identified a low albumin, advanced age and ER negativity as independent predictors of poor survival. The time interval between primary and metastatic disease, metastases at extrahepatic sites, histological subtype and nodal stage at primary presentation did not predict prognosis. Awareness of the prognostic implications of the above factors may assist in selecting the most appropriate treatment for these patients.British Journal of Cancer (2003) 89, 284-290. doi:10.1038/sj.bjc.6601038 www.bjcancer.com

    Several studies showed potential for monitoring response to systemic therapy in metastatic colorectal cancer patients with {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography (PET). Before {sup 18}F-FDG PET can be implemented for response evaluation the repeatability should be known. This study was performed to assess the magnitude of the changes in standardized uptake value (SUV), volume and total lesion glycolysis (TLG) in colorectal liver metastases and validate the biological basis of {sup 18}F-FDG PET in colorectal liver metastases. Twenty patients scheduled for liver metastasectomy underwent two {sup 18}F-FDG PET scans within 1 week. Bland-Altman analysis was performed to assess repeatability of SUV{sub max}, SUV{sub mean}, volume and TLG. Tumours were delineated using an adaptive threshold method (PET{sub SBR}) and a semiautomatic fuzzy locally adaptive Bayesian (FLAB) delineation method. Coefficient of repeatability of SUV{sub max} and SUV{sub mean} were {proportional_to}39 and {proportional_to}31 %, respectively, independent of the delineation method used and image reconstruction parameters. However, repeatability was worse in recently treated patients. The FLAB delineation method improved the repeatability of the volume and TLG measurements compared to PET{sub SBR}, from coefficients of repeatability of over 85 % to 45 % and 57 % for volume and TLG, respectively. Glucose transporter 1 (GLUT1) expression correlated to the SUV{sub mean}. Vascularity (CD34 expression) and tumour hypoxia (carbonic anhydrase IX expression) did not correlate with {sup 18}F-FDG PET parameters. In conclusion, repeatability of SUV{sub mean} and SUV{sub max} was mainly affected by preceding systemic therapy. The repeatability of tumour volume and TLG could be improved using more advanced and robust delineation approaches such as FLAB, which is recommended when {sup 18}F-FDG PET is utilized for volume or TLG measurements.

    Background: Management of patients after locally ablative treatment of liver metastases requires exact information about local control and systemic disease status. To fulfill these requirements, whole-body imaging using positron emission tomography with {sup 18}F-fluorodeoxyglucose (FDG-PET) is a promising alternative to morphologic imaging modalities such as computed tomography (CT) and magnetic resonance imaging (MRI). Purpose: To evaluate FDG-PET for the assessment of local control and systemic disease in patients with clinical suspicion of tumor progression after laser-induced thermotherapy (LITT) of colorectal liver metastases. Material and Methods: In 21 patients with suspicion of progressive disease after LITT, whole-body FDG-PET was performed. The presence of viable tumor within treated lesions, new liver metastases, and extrahepatic disease was evaluated visually and semi quantitatively (maximal standard uptake value [SUVmax], tumor-to-normal ratio [T/N]). The standard of reference was histopathology (n = 25 lesions) and/or clinical follow-up (>12 months) including contrast-enhanced MRI of the liver. Results: Among 54 metastases treated with LITT, 29 had residual tumor. Receiver operating characteristic (ROC) analysis of SUVmax (area under the curve (AUC) 0.990) and T/N (AUC 0.968) showed a significant discrimination level of negative or positive lesion status with an equal accuracy of 94% (51/54). The overall accuracy of visual FDG-PET was 96% (52/54), with one false-negative lesion among six examined within 3 days after LITT, and one false-positive lesion examined 54 days after LITT. In the detection of new intra- and extrahepatic lesions, FDG-PET resulted in correct alteration of treatment strategy in 43% of patients (P = 0.007). Conclusion: FDG-PET is a promising tool for the assessment of local control and whole-body restaging in patients with clinical suspicion of tumor progression after locally ablative treatment of colorectal liver metastases with

    Purpose: before locally ablative treatment of colorectal liver metastases, patients have to be carefully evaluated to decide whether this is the adequate therapy. In this study we determined the value of FDG-PET in comparison to conventional staging procedures. Patients, methods: in 68 consecutive patients referred for laser induced thermotherapy (LITT) of liver metastases from colorectal cancer, pre-therapeutic staging with conventional imaging (thoracic and abdominal CT, liver MRI, chest X-ray) and FDG-PET was performed. The examinations were analysed separately and blinded. Based on the staging information, therapeutic decisions were made by an interdisciplinary review board according to a standardized algorithm. The results were compared between conventional imaging and FDG-PET, and were validated by clinical follow up data and histopathology, respectively. Results: on FDG-PET 210 lesions were interpreted as tumour manifestations. 48 of these were not seen on conventional imaging (true positive, n = 46). In contrast, 24 lesions were visualized by conventional imaging only (true positive, n = 12). Compared to conventional imaging, discrepant findings on FDG-PET led to treatment modifications in 25 patients (37%); these were correct in 20/25 patients. According to the actual treatment course, the inadequate treatment modifications in the remaining 5 patients were avoided by further diagnostic procedures (i.e. biopsies). Conclusions: In the evaluation of patients with known liver metastases from colorectal cancer before LITT, FDG-PET depicts relevant findings subsidiary to conventional imaging and thus is of high value for therapeutic decision making.

    Colorectal cancer is one of the few malignant tumors in which synchronous or metachronous liver metastases [colorectal liver metastases (CRLMs)] may be treated with surgery. It has been demonstrated that resection of CRLMs improves the long-term prognosis. On the other hand, patients with un-resectable CRLMs may benefit from chemotherapy alone or in addition to liver-directed therapies. The choice of the most appropriate therapeutic management of CRLMs depends mostly on the diagnostic imaging. Nowadays, multiple non-invasive imaging modalities are available and those have a pivotal role in the workup of patients with CRLMs. Although extensive research has been performed with regards to the diagnostic performance of ultrasonography, computed tomography, positron emission tomography and magnetic resonance for the detection of CRLMs, the optimal imaging strategies for staging and follow up are still to be established. This largely due to the progressive technological and pharmacological advances which are constantly improving the accuracy of each imaging modality. This review describes the non-invasive imaging approaches of CRLMs reporting the technical features, the clinical indications, the advantages and the potential limitations of each modality, as well as including some information on the development of new imaging modalities, the role of new contrast media and the feasibility of using parametric image analysis as diagnostic marker of presence of CRLMs.

    Image-guided tumor ablation techniques have significantly broadened the treatment possibilities for primary and secondary hepatic malignancies. A new ablation technique, irreversible electroporation (IRE), was recently added to the treatment armamentarium. As opposed to thermal ablation, cell death with IRE is primarily induced using electrical energy: electrical pulses disrupt the cellular membrane integrity, resulting in cell death while sparing the extracellular matrix of sensitive structures such as the bile ducts, blood vessels, and bowel wall. The preservation of these structures makes IRE attractive for colorectal liver metastases (CRLM) that are unsuitable for resection and thermal ablation owing to their anatomical location. This review discusses different technical and practical issues of IRE for CRLM: the indications, patient preparations, procedural steps, and different "tricks of the trade" used to improve safety and efficacy of IRE. Imaging characteristics and early efficacy results are presented. Much is still unknown about the exact mechanism of cell death and about factors playing a crucial role in the extent of cell death. At this time, IRE for CRLM should only be reserved for small tumors that are truly unsuitable for resection or thermal ablation because of abutment of the portal triad or the venous pedicles.

    The prevalence of thyroid metastases in colorectal cancer (CRC) patients is unknown. We retrieved the records of all patients with CRC and pathologically proved thyroid metastasis for the period 1993-2004. Among 5,862 consecutive patients with CRC, 6 (0.1%) were diagnosed with thyroid metastases, a median of 61 months after the diagnosis of primary tumour, and a median of 19 months after the last surgical resection or radiofrequency ablation of other metastases (which were present in all cases). Signs and symptoms, when present (n=3), consisted of cervical pain, cervical adenopathy, goitre, dysphagia, and/or dysphonia. In other cases, the diagnosis was made by positron emission tomography scanning. Thyroidectomy was performed in the 5 patients with isolated thyroid metastases, with cervical lymph node dissection being required in all cases. The only patient treated conservatively because of concomitant liver and lung metastases developed life-threatening dyspnoea, which required emergent tracheal stenting. Median overall survival was 77 months, 58 months, and 12 months after the diagnosis of primary CRC, initial metastases, and thyroid metastasis, respectively. It is concluded that thyroid metastases are rare and occur late in the course of CRC. Thyroidectomy (with cervical lymph node dissection) may result in prevention or improvement of life-threatening symptoms and prolonged survival.

    Full Text Available Abstract Background Despite the fact that metastases are the leading cause of colorectal cancer deaths, little is known about the underlying molecular changes in these advanced disease stages. Few have studied the overall gene expression levels in metastases from colorectal carcinomas, and so far, none has investigated the peritoneal carcinomatoses by use of DNA microarrays. Therefore, the aim of the present study is to investigate and compare the gene expression patterns of primary carcinomas (n = 18, liver metastases (n = 4, and carcinomatoses (n = 4, relative to normal samples from the large bowel. Results Transcriptome profiles of colorectal cancer metastases independent of tumor site, as well as separate profiles associated with primary carcinomas, liver metastases, or peritoneal carcinomatoses, were assessed by use of Bayesian statistics. Gains of chromosome arm 5p are common in peritoneal carcinomatoses and several candidate genes (including PTGER4, SKP2, and ZNF622 mapping to this region were overexpressed in the tumors. Expression signatures stratified on TP53 mutation status were identified across all tumors regardless of stage. Furthermore, the gene expression levels for the in vivo tumors were compared with an in vitro model consisting of cell lines representing all three tumor stages established from one patient. Conclusion By statistical analysis of gene expression data from primary colorectal carcinomas, liver metastases, and carcinomatoses, we are able to identify genetic patterns associated with the different stages of tumorigenesis.

    Full Text Available Liver metastases from colorectal cancer (CRC result in substantial morbidity and mortality. The primary treatment is systemic chemotherapy, and in selected patients, surgical resection; however, for patients who are not surgical candidates and/or fail systemic chemotherapy, liver-directed therapies are increasingly being utilized. Yttrium-90 (Y-90 microsphere therapy, also known as selective internal radiation therapy (SIRT or radioembolization, has proven to be effective in terms of extending time to progression of disease and also providing survival benefit. This review focuses on the use of Y-90 microsphere therapy in the treatment of liver metastases from CRC, including a comprehensive review of published clinical trials and prospective studies conducted thus far. We review the methodology, outcomes and side effects of Y-90 microsphere therapy for metastatic CRC

    2016-01-01

    Patients with newly diagnosed colorectal cancer (CRC) are subjected to a preoperative thoraco-abdominal CT scan to determine the cancer stage. This staging is of relevance with regard to treatment and prognosis. About 20% of the patients have distant metastatic spread at the time of diagnosis, i.......e. synchronous metastases. Most common are hepatic metastases followed by pulmonary involvement. The optimal staging modality for detecting synchronous pulmonary metastases is debated. It has been argued, that synchronous pulmonary metastases (SPCM) are rare in CRC and that the consequence of detecting SPCM...... is minimal. Furthermore, the current staging practice is complicated by a high number of incidental findings on the thoracic CT, so-called indeterminate pulmonary nodules (IPN). IPN can potentially represent SPCM. The purpose of this thesis was to estimate the prevalence, characteristics and clinical...

In 5 of the 11 patients, matched samples from the primary tumor...... and lymph node metastases were analyzed. Cytogenetic similarities between the primary and secondary lesions were found in all 5 cases, indicating that many of the chromosomal aberrations presumably occurred before disease spreading took place.

    AIM: To evaluate and compare the expression profiles of CXCL12 (SDF-1), CCL19 (MIP-3β), CCL20 (MIP-3α) and CCL21 (6Ckine, Exodus2) and their receptors on RNA and protein levels in hepatocellular carcinoma (HCC) versus colorectal liver metastases (CRLM) and to elucidate their impact on the carcinogenesis and progression of malignant liver diseases.METHODS: Chemokine expression was analyzed by RT-PCR and ELISA in 11 cases of HCC specimens and in 23 cases of CRLM and corresponding adjacent nontumorous liver tissues, respectively. Expressions of their receptors CXCR4, CCR6 and CCR7 were analyzed by RTPCR and Western blot analysis in the same cases of HCC and CRLM.RESULTS: Significant up-regulation for CCL20/CCR6 was detected in both cancer types. Moreover, CCL20demonstrated significant overexpression in CRLM in relation to the HCC tissues. Being significantly upregulated only in CRLM, CXCR4 displayed an aberrant expression pattern with respect to the HCC tissues.CONCLUSION: Correlation of CXCR4 expression with CRLM suggests CXCR4 as a potential predictive factor for CRLM. High level expression of CCL20 and its receptor CCR6 in HCC and CRLM with marked upregulation of CCL20 in CRLM in relation to HCC tissues indicates involvement of the CCL20/CCR6 ligand-receptor pair in the carcinogenesis and progression of hepatic malignancies.

    Follicular thyroid carcinoma (FTC) is the second most common type of thyroid cancer (TC) and accounts for approximately 10% of all TC cases. Liver metastases are a rare presentation in 0.5-1% of follicular thyroid cancers, usually occurring in the setting of widely disseminated FTC disease, and their presence is associated with poor prognosis. Until now, there have been only 30 cases of FTC liver metastases described in the literature. Herein, we review publications and describe diagnostic tools that may be used in the diagnosis and follow-up of FTC metastases to the liver, including biopsy and imaging techniques like US, CT, MRI, SPECT, PET, and radioiodine scintigraphy. We also present and discuss current methods of treatment, e.g. TSH suppressive therapy with levothyroxine, surgery, radiofrequency ablation (RFA), transarterial embolisation (TAE), liver transarterial chemoembolisation (TACE), chemotherapy with cisplatin and doxorubicin, treatment with Indium- 111-octreotide (or its analogues), and tyrosine kinase inhibitors (sorafenib, sunitinib). At the end we describe the course, results of diagnostics, and treatment in a patient with large multiple FTC metastases to the liver. (Endokrynol Pol 2016; 67 (3): 332-347).

    In patients with metastatic colorectal cancer, the liver is the most common site of metastatic disease. In patients with liver-dominant disease, consideration needs to be given to locoregional treatments such as hepatic arterial infusion chemotherapy, transarterial chemoembolisation and selective internal radiation therapy because hepatic metastases are a major cause of liver failure especially in chemorefractory disease. In this review we provide insights on the published literature for locoregional treatment of liver metastases in metastatic colorectal cancer.

    Available literature on the differences in circulation and microcirculation of normal liver and liver metastases as well as in rheology of the different radiolabelled microspheres [(99m)Tc-labelled macroaggregates of albumin (MAA), (90)Y-TheraSpheres and (90)Y-SIR-spheres] used in selective internal radiation therapy (SIRT) are reviewed and implications thereof on the practice of SIRT discussed. As a result of axial accumulation and skimming, large microspheres are preferentially deposited in regions of high flow, whereas smaller microspheres are preferentially diverted to regions of low flow. As flow to normal liver tissue is considerably variable between segments and also within one segment, microspheres will be delivered heterogeneously within the microvasculature of normal liver tissue. This non-uniformity in microsphere distribution in normal liver tissue has a significant "liver-sparing" effect on the dose distribution of (90)Y-labelled microspheres. Arterial flow to liver metastases is most pronounced in the hypervascular rim of metastases, followed by the smaller metastases and finally by the central hypoperfused region of the larger metastases. Because of the wide variability in size of labelled MAAs and because of the skimming effect, existing differences in flow between metastatic lesions of variable size are likely exaggerated on (99m)Tc-MAA scintigraphy when compared to (90)Y-TheraSpheres and (90)Y-SIR-spheres (smaller variability in size and probably also in specific activity). Ideally, labelled MAAs would contain a size range similar to that of (90)Y-SIR-spheres or (90)Y-TheraSpheres. Furthermore, the optimal number of MAA particles to inject for the pretreatment planning scintigraphy warrants further exploration as it was shown that concentrated suspensions of microspheres produce more optimal tumour to normal liver distribution ratios. Finally, available data suggest that the flow-based heterogeneous distribution of microspheres to metastatic

    Functional tumor volume (FTV) and total lesion glycolysis (TLG) are measures of metabolic activity of tumors determined by fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT images. These parameters could potentially have clinical value in response to treatment evaluation and disease prognostication. The objectives of this study were to investigate the relationship between functional tumor parameters (FTV and TLG) and clinical outcomes in patients with colorectal cancer liver metastases (CRCLM) undergoing {sup 90}Y-resin microsphere selective internal radiation therapy (SIRT) (SIR-Spheres {sup registered}, Sirtex Medical Limited, Lane Cove, NSW, Australia). FDG PET/CT studies of 20 patients with unresectable CRCLM who underwent {sup 90}Y SIRT under a phase II clinical trial were analyzed. FTV and TLG were calculated using PET VCAR (GE Healthcare, Milwaukee, WI, USA) on pretreatment and 4-week posttreatment scans. The effects of pretreatment and posttreatment functional tumor activity on patient survival were evaluated using Kaplan-Meier survival curves. The median survival in the study group was 14.8 months (range 2.0-27.7 months). The median survival for patients with pretreatment FTV values of above and below 200 cc were 11.2 and 26.9 months, respectively (p < 0.05). The median survival for patients with 4-week posttreatment FTV values of above and below 30 cc were 10.9 and 26.9 months, respectively (p < 0.05). The median survival for patients with pretreatment TLG values of above and below 600 g were 11.2 and 26.9 months, respectively (p < 0.05). The median survival for patients with 4-week posttreatment TLG values of above and below 100 g were 10.9 and 26.9 months, respectively (p < 0.05). Pretreatment and posttreatment FTV and TLG showed very strong association with survival. These values can be useful quantitative criteria for patient selection and disease prognostication when {sup 90}Y SIRT is contemplated in patients with CRCLM. (orig.)

    Liver resection is the treatment of choice for patients with colorectal liver metastases(CLM).However,major resections are often required to achieve R0 resection,which are associated with substantial rates of morbidity and mortality.Maximizing the amount of residual liver gained increasing significance in modern liver surgery due to the high incidence of chemotherapyassociated parenchymal injury.This fact,along with the progressive expansion of resectability criteria,has led to the development of a surgical philosophy known as "parenchymal-sparing liver surgery"(PSLS).This philosophy includes a variety of resection strategies,either performed alone or in combination with ablative therapies.A profound knowledge of liver anatomy and expert intraoperative ultrasound skills are required to perform PSLS appropriately and safely.There is a clear trend toward PSLS in hepatobiliary centers worldwide as current evidence indicates that tumor biology is the most important predictor of intrahepatic recurrence and survival,rather than the extent of a negative resection margin.Tumor removal avoiding the unnecessary sacrifice of functional parenchyma has been associated with less surgical stress,fewer postoperative complications,uncompromised cancer-related outcomes and higher feasibility of future resections.The increasing evidence supporting PSLS prompts its consideration as the gold-standard surgical approach for CLM.

    In this study, we evaluate the efficacy of low-dose cisplatin and continuous 5-FU infusion systemic chemotherapy (LFP therapy) for the treatment of unresectable and recurrent liver metastases from colorectal cancer after weekly high-dose 5-FU therapy via the hepatic artery (WHF therapy). At the start of chemotherapy, 12 patients with multiple extrahepatic lesions were treated with the LFP therapy (LFP group), and 18 patients with none or a few extrahepatic lesions were treated with the WHF therapy followed by the LFP therapy (LFP after WHF group). In the LFP group, the response rate was 50.0% (PR 6) and the one-year survival rate was 50.0%. On the contrary, in the LFP after WHF group, the response rate was 38.9% (CR 1, PR 6) and the one-year survival rate after LFP started was 46.0%. We conclude that the LFP therapy may be effective for the treatment of liver metastases from colorectal cancer even after the WHF therapy.

    The liver is, second only to lymph nodes, the most common site for metastatic disease irrespective of the primary tumour. More than 50% of all patients with malignant diseases will develop liver metastases with a significant morbidity and mortality. Although the surgical resection leads to an improved survival in patients with colorectal metastases, only approximately 20% of patients are eligible for surgery. Thermal ablation and especially radiofrequency ablation emerge as an important additional therapy modality for the treatment of liver metastases. RF ablation shows a benefit in life expectancy and may lead in a selected patient group to cure. Percutaneous RF ablation appears safer (versus cryotherapy), easier (versus laser), and more effective (versus ethanol instillation and transarterial chemoembolisation) compared with other minimally invasive procedures. RF ablation can be performed by a percutaneous, laparoscopical or laparotomic approach, and may be potentially combined with chemotherapy and surgery. At present ideal candidates have tumours with a maximum diameter less than 3.5 cm. An untreatable primary tumour or a systemic disease represents contraindications for performing local therapies. Permanent technical improvements of thermal ablation devices and a better integration of thermal ablation in the overall patient care may lead to prognosis improvement in patients with liver metastases.

    Full Text Available Abstract Background To prospectively evaluate the efficacy and safety of selective internal radiation (SIR spheres in patients with inoperable liver metastases from colorectal cancer who have failed 5FU based chemotherapy. Methods Patients were prospectively enrolled at three Australian centres. All patients had previously received 5-FU based chemotherapy for metastatic colorectal cancer. Patients were ECOG 0–2 and had liver dominant or liver only disease. Concurrent 5-FU was given at investigator discretion. Results Thirty patients were treated between January 2002 and March 2004. As of July 2004 the median follow-up is 18.3 months. Median patient age was 61.7 years (range 36 – 77. Twenty-nine patients are evaluable for toxicity and response. There were 10 partial responses (33%, with the median duration of response being 8.3 months (range 2–18 and median time to progression of 5.3 mths. Response rates were lower (21% and progression free survival shorter (3.9 mths in patients that had received all standard chemotherapy options (n = 14. No responses were seen in patients with a poor performance status (n = 3 or extrahepatic disease (n = 6. Overall treatment related toxicity was acceptable, however significant late toxicity included 4 cases of gastric ulceration. Conclusion In patients with metastatic colorectal cancer that have previously received treatment with 5-FU based chemotherapy, treatment with SIR-spheres has demonstrated encouraging activity. Further studies are required to better define the subsets of patients most likely to respond.

    Breast cancer represents the second most frequent cause of brain metastases. Treatment planning should consider several tumor and patient factors to estimate prognosis based on the Karnofsky Performance Status (KPS), age, extent of extra-cerebral disease as well as genetic subtype. When systemic disease is under control patients with up to three metastases qualify for local therapy, such as surgical excision or stereotactic radiotherapy. After the local treatment the addition of whole brain radiation therapy may be postponed until disease progression in the brain is observed and overall survival will not be compromised. Asymptomatic brain metastases may be first approached with a systemic treatment to which the primary tumor is considered to be sensitive.

    Summary: Metastases from uveal melanoma are often confined to the liver. Palliative hepatic chemoembolization has been considered to be a reasonable treatment approach. We enrolled 14 patients with hepatic metastases from uveal melanoma into a pilot trial of transarterial chemoembolization (TACE). All patients received additional systemic immuno-chemotherapy or best supportive care. In 31 procedures 100 mg/m{sup 2} of cisplatine was continuously infused by means of a power injector preceding embolization by manual injection of polyvinyl alcohol particles. In three procedures cisplatine was replaced by 200 mg/m{sup 2} carboplatine because of increased serum creatinine levels. Tumor response was evaluated using RECIST criteria. Fourteen patients received 34 TACE's (mean: 2.4 treatments). Eight patients (57%) achieved partial response (PR), four patients (29%) had stable disease and two patients (14%) tumor progression. Median time to progression was 8.5 months (5-35 months). Median survival after first TACE was 14.5 months in responders compared to 10 months in non-responders (p = 0.18, not significant) and 11.5 months (3-69 months) in all patients. In seven patients with metastases occupying less than 25% of liver volume median survival was 17 months compared to 11 months in seven patients with tumor involvement of more than 25% (p = 0.02) with partial response rate of 86% and 29%, respectively. TACE of liver metastases from uveal melanoma is well tolerated and may prolong survival in patients with limited tumor extension.

  13. Hepatic arterial infusion pump chemotherapy for colorectal liver metastases: an old technology in a new era.

    2014-02-01

    Aggressive treatment of colorectal cancer (crc) liver metastases can yield long-term survival and cure. Unfortunately, most patients present with technically unresectable metastases; conventional therapy in such patients consists of systemic therapy. Despite advances in the effectiveness of systemic therapy in the first-line setting, the tumour response rate and median survival remain low in the second-line setting. The preferential blood supply from the hepatic artery to crc liver metastases allows for excellent regional delivery of chemotherapy. Here, we review efficacy and safety data for hepatic artery infusion (hai) pump chemotherapy in patients with metastatic crc from the 5-fluorouracil era and from the era of modern chemotherapy. In selected patients with liver-only or liver-dominant disease who have progressed on first-line chemotherapy, hai combined with systemic agents is a viable therapeutic option when performed at experienced centres. Furthermore, significantly improved survival has been demonstrated with adjuvant hai therapy after liver resection in the phase iii setting. The complication rates and local toxicities associated with hai pump therapy are infrequent at experienced centres and can be managed with careful follow-up and early intervention. The major obstacles to the wide adoption of hai therapy include technical expertise for pump insertion and maintenance, and for floxuridine dose modification. The creation of formal preceptor-focused education and training in hai therapy for interdisciplinary medical professionals might encourage the creation and expansion of this liver-directed approach.

    Von Meyenburg complexes are benign liver lesions consisting of adenomatous bile duct proliferates. We present two patients suffering from esophageal cancer accompanied by the occurrence of von Meyenburg complexes.Preoperative computerized tomography (CT) of the liver had not shown these lesions. In one of the patients, diffuse nodular manifestation was found in both liver lobes,mimicking diffuse hepatic metastases. Intraoperative frozen section revealed the benign nature of the lesions in both cases. The patients underwent esophageal resection without complications. To the best of our knowledge, the coincidence of von Meyenburg complexes and esophageal cancer has never been reported before. This uncommon entity should be taken into consideration as a differential diagnosis of liver lesions in malignancies. It underlines the importance of intraoperative frozen section for liver lesions of unknown origin.

    This study evaluated the predictive role of 1D, 2D and 3D quantitative, enhancement-based MRI regarding overall survival (OS) in patients with colorectal liver metastases (CLM) following intra-arterial therapies (IAT). This retrospective analysis included 29 patients who underwent transarterial chemoembolization (TACE) or radioembolization and received MRI within 6 weeks after therapy. Tumour response was assessed using 1D and 2D criteria (such as European Association for the Study of the Liver guidelines [EASL] and modified Response Evaluation Criteria in Solid Tumors [mRECIST]). In addition, a segmentation-based 3D quantification of overall (volumetric [v] RECIST) and enhancing lesion volume (quantitative [q] EASL) was performed on portal venous phase MRI. Accordingly, patients were classified as responders (R) and non-responders (NR). Survival was evaluated using Kaplan-Meier analysis and compared using Cox proportional hazard ratios (HR). Only enhancement-based criteria identified patients as responders. EASL and mRECIST did not predict patient survival (P = 0.27 and P = 0.44, respectively). Using uni- and multivariate analysis, qEASL was identified as the sole predictor of patient survival (9.9 months for R, 6.9 months for NR; P = 0.038; HR 0.4). The ability of qEASL to predict survival early after IAT provides evidence for potential advantages of 3D quantitative tumour analysis. (orig.)

    . Moreover, a signature was developed based on our unsupervised clustering of breast tumors and this was predictive for disease-specific survival in three independent studies. Next, the metastases from ovarian, breast, lung and vulva cluster with their tissue of origin while metastases from colon showed a bimodal distribution. A significant part clusters with tissue of origin while the remaining tumors cluster with the tissue of destination. Conclusion Our molecular taxonomy of epithelial human cancer indicates surprising correlations over tissues. This may have a significant impact on the classification of many cancer sites and may guide pathologists, both in research and daily practice. Moreover, these results based on unsupervised analysis yielded a signature predictive of clinical outcome in breast cancer. Additionally, we hypothesize that metastases from gastrointestinal origin either remember their tissue of origin or adapt to the tissue of destination. More specifically, colon metastases in the liver show strong evidence for such a bimodal tissue specific profile.

    Purpose: Accurate segmentation and quantification of liver metastases on CT images are critical to surgery/radiation treatment planning and therapy response assessment. To date, there are no reliable methods to perform such segmentation automatically. In this work, the authors present a method for semiautomatic delineation of liver metastases on contrast-enhanced volumetric CT images. Methods: The first step is to manually place a seed region-of-interest (ROI) in the lesion on an image. This ROI will (1) serve as an internal marker and (2) assist in automatically identifying an external marker. With these two markers, lesion contour on the image can be accurately delineated using traditional watershed transformation. Density information will then be extracted from the segmented 2D lesion and help determine the 3D connected object that is a candidate of the lesion volume. The authors have developed a robust strategy to automatically determine internal and external markers for marker-controlled watershed segmentation. By manually placing a seed region-of-interest in the lesion to be delineated on a reference image, the method can automatically determine dual threshold values to approximately separate the lesion from its surrounding structures and refine the thresholds from the segmented lesion for the accurate segmentation of the lesion volume. This method was applied to 69 liver metastases (1.1–10.3 cm in diameter) from a total of 15 patients. An independent radiologist manually delineated all lesions and the resultant lesion volumes served as the “gold standard” for validation of the method’s accuracy. Results: The algorithm received a median overlap, overestimation ratio, and underestimation ratio of 82.3%, 6.0%, and 11.5%, respectively, and a median average boundary distance of 1.2 mm. Conclusions: Preliminary results have shown that volumes of liver metastases on contrast-enhanced CT images can be accurately estimated by a semiautomatic segmentation

    Full Text Available Abstract Background The local and systemic activation and regulation of the immune system by malignant cells during carcinogenesis is highly complex with involvement of the innate and acquired immune system. Despite the fact that malignant cells do have antigenic properties their immunogenic effects are minor suggesting tumor induced mechanisms to circumvent cancer immunosurveillance. The aim of this study is the analysis of tumor immune escape mechanisms in a colorectal liver metastases mouse model at different points in time during tumor growth. Methods CT26.WT murine colon carcinoma cells were injected intraportally in Balb/c mice after median laparotomy using a standardized injection technique. Metastatic tumor growth in the liver was examined by standard histological procedures at defined points in time during metastatic growth. Liver tissue with metastases was additionally analyzed for cytokines, T cell markers and Fas/Fas-L expression using immunohistochemistry, immunofluorescence and RT-PCR. Comparisons were performed by analysis of variance or paired and unpaired t test when appropriate. Results Intraportal injection of colon carcinoma cells resulted in a gradual and time dependent metastatic growth. T cells of regulatory phenotype (CD4+CD25+Foxp3+ which might play a role in protumoral immune response were found to infiltrate peritumoral tissue increasingly during carcinogenesis. Expression of cytokines IL-10, TGF-β and TNF-α were increased during tumor growth whereas IFN-γ showed a decrease of the expression from day 10 on following an initial increase. Moreover, liver metastases of murine colon carcinoma show an up-regulation of FAS-L on tumor cell surface with a decreased expression of FAS from day 10 on. CD8+ T cells express FAS and show an increased rate of apoptosis at perimetastatic location. Conclusions This study describes cellular and macromolecular changes contributing to immunological escape mechanisms during metastatic

    To investigate whether the different location of pancreatic adenocarcinoma affects the lobar distribution of metastases to the liver. From all patients who underwent multidetector computed tomography (MDCT) examinations for staging of pancreatic adenocarcinoma in the last 4 years we selected 80 patients (42 men, 38 women; mean age, 60.56 years) with liver metastases and a pancreatic adenocarcinoma of the head (group A, 40 patients; diameter, 32.41 ± 2.28 mm) or body-tail (group B, 40 patients; diameter, 52.21 ± 2.8 mm). We analysed tumour site, diameter, vascular invasion and number of metastases in each lobe of the liver. The total number of metastases was compared between the two groups with an unpaired t-test, while Fisher's test was used to compare the number of metastases within the two lobes. As expected, the number of liver metastases was higher in group B than in group A. The ratio of metastases in the right-to-left hemi-liver was 7.4:1 for group A compared with 3.3:1 for group B (p < 0.0001). Although the number of liver metastases is higher in the right lobe than in the left lobe in both groups, there is a significant difference in the ratio of metastases between the right and the left hemi-liver. This supports the existence of a streamline phenomenon and a selective lobar distribution of metastases within the liver. (orig.)

    AIM: To evaluate the influence of preoperative FOLFOX chemotherapy on CCL20/CCR6 expression in liver metastases of stage Ⅳ colorectal cancer (CRC) patients. METHODS: Using Real Time-PCR, enzyme-linked immunosorbent assay, Western Blots and immunohistochemistry, we have analyzed the expression of CCL20, CCR6 and proliferation marker Ki-67 in colorectal liver metastasis (CRLM) specimens from stage Ⅳ CRC patients who received preoperative FOLFOX chemotherapy (n = 53) and in patients who did not receive FOLFOX chemotherapy prior to liver surgery (n = 29). RESULTS: Of the 53 patients who received FOLFOX, time to liver surgery was ≤ 1 mo in 14 patients, ≤ 1 year in 22 patients and > 1 year in 17 patients, respectively. In addition, we investigated the proliferation rate of CRC cells in liver metastases in the different patient groups. Both CCL20 and CCR6 mRNA and protein expression levels were significantly increased in patients who received preoperative FOLFOX chemotherapy ≤ 12 mo before liver surgery (P < 0.001) in comparison to patients who did not undergo FOLFOX treatment. Further, proliferation of CRLM cells as measured by Ki-67 was increased in patients who underwent FOLFOX treatment. CCL20 and CCR6 expression levels were significantly increased in CRLM patients who had undergone preoperative FOLFOX chemotherapy. CONCLUSION: This chemokine/receptor up-regulation could lead to increased proliferation/migration through an autocrine mechanism which might be used by surviving metastatic cells to escape cell death caused by FOLFOX.

    Prostate cancer has a distinctly recognized pattern of metastases: multifocal and osteoblastic lesions involving the axial skeleton and non-calcified lymph nodes in the pelvic and lumbar aortic groups. Most adenocarcinomas are capable of producing macrocalcification. We report a case of prostate cancer with de novo calcified metastases to the liver and retroperitoneal lymph nodes mimicking the pattern usually seen in mucin-producing adenocarcinomas arising from the gastrointestinal tract. To our knowledge, this is the first such case to be reported in the literature. We propose a multifactorial mechanism that supports dystrophic calcification in this case. The knowledge of atypical presentation of metastatic disease can prevent diagnostic delay and prompt initiation of therapy.

    To compare gadoxetic acid alone and combined gadoxetic acid/gadofosveset trisodium-enhanced liver MRI for detection of metastases and differentiation of metastases from haemangiomas. Ninety-one patients underwent gadoxetic acid-enhanced liver MRI before and after additional injection of gadofosveset. First, two readers retrospectively identified metastases on gadoxetic acid alone enhanced delayed hepatobiliary phase T1-weighted images together with all other MR images (dynamic images, T2-weighted images, diffusion-weighted images). Second, readers assessed additional T1-weighted images obtained after administration of gadofosveset trisodium. For both interpretations, readers rated lesion conspicuity and confidence in differentiating metastases from haemangiomas. Results were compared using alternative free-response receiver-operating characteristic (AFROC) and conventional ROC methods. Histology and follow-up served as reference standard. There were 145 metastases and 16 haemangiomas. Both readers detected more metastases using combined gadoxetic acid/gadofosveset (reader 1 = 130; reader 2 = 124) compared to gadoxetic acid alone (reader 1 = 104; reader 2 = 103). Sensitivity of combined gadoxetic acid/gadofosveset (reader 1 = 90 %; reader 2 = 86 %) was higher than that of gadoxetic acid alone (reader 1 = 72 %; reader 2 = 71 %, both P < 0.01). AFROC-AUC was higher for the combined technique (0.92 vs. 0.86, P < 0.001). Sensitivity for correct differentiation of metastases from haemangiomas was higher for the combined technique (reader 1 = 98 %; reader 2 = 99 % vs. reader 1 = 86 %; reader 2 = 91 %, both P < 0.01). ROC-AUC was significantly higher for the combined technique (reader 1 = 1.00; reader 2 = 1.00 vs. reader 1 = 0.87; reader 2 = 0.92, both P < 0.01). Combined gadoxetic acid/gadofosveset-enhanced MRI improves detection and characterization of liver metastases compared to gadoxetic acid alone. (orig.)

    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).

    Colorectal cancer (CRC) is one of the leading causes of cancer-related death. Surgery, radiotherapy and chemotherapy have been till now the main therapeutic strategies for disease control and improvement of the overall survival. Twenty-five per cent (25%) of CRC patients have clinically detectable liver metastases at the initial diagnosis and approximately 50% develop liver metastases during their disease course. Twenty-thirty per cent (20%-30%) are CRC patients with metastases confined to the liver. Some years ago various studies showed a curative potential for liver metastases resection. For this reason some authors proposed the conversion of unresectable liver metastases to resectable to achieve cure. Since those results were published, a lot of regimens have been studied for resectability potential. Better results could be obtained by the combination of chemotherapy with targeted drugs, such as anti-VEGF and anti-EGFR monoclonal antibodies. However an accurate selection for patients to treat with these regimens and to operate for liver metastases is mandatory to reduce the risk of complications. A multidisciplinary team approach represents the best way for a proper patient management. The team needs to include surgeons, oncologists, diagnostic and interventional radiologists with expertise in hepatobiliary disease, molecular pathologists, and clinical nurse specialists. This review summarizes the most important findings on surgery and systemic treatment of CRC-related liver metastases.

    Hepatocellular carcinoma(HCC) is the fifth most common cancer in the world, and is the third leading cause of cancer-related death. Liver transplantation(LT) has become a curative treatment for patients with HCC. However, recurrence and metastasis after LT are the main factors reducing long-term survival in patients, and the lung is the most common site of metastasis after LT for HCC, although metastasis to liver, para-aortic lymph nodes and renal periphery are observed. Thus, the treatment of pulmonary metastases after LT for HCC has become a hot research topic, the successful treatment of pulmonary metastases can significantly prolong the survival of LT patients. Although single conventional treatment(chemotherapy, surgery and external beam radiation therapy), immunosuppression, image-guided minimally invasive therapy(radiofrequency ablation, microwave ablation, cryoablation, and brachytherapy) and molecular targeted drugs have had a significant effect, patients do not have durable remission and the long-term survival rate is disappointing. Therefore, improving existing treatments and identifying a more effective combination therapy are important research issues in the prevention and treatment of pulmonary metastases after LT for HCC. The paper reviewed single conventional treatments, new treatments, and combination therapy, to provide a basis for the best treatment of these patients.

    Objective:To analyze the clinical course and treatment result of lung metastases from breast cancer. Method:122 cases with lung metastases from breast cancer were treated with chemotherapy or chemotherapy plus endocrine therapy, response was assessed according to WHO criteria and survival rate estimated using the life Table. Results: The median time from initial treatment of primary tumor to lung metastases was 22 months. Sites of common consecutive metastases were lung, liver and bone. The overall response rate was 48% with a CR rate of 15%. Compared to non- DDP- encompassing regimen, the CR rate was higher in DDP-based chemotherapy (7%versus 21%, P<0.05) with a longer median survival time (MST). The PR rate was higher in regimens containing anthracycline (48%) than in those without anthracycline (20%, P<0.01). The response rate was similar between chemotherapy and chemotherapy plus endocrine therapy (P>0.05). No difference in MST was observed between patients receiving anthracycline-and non-anthracyclineencompassing regimens. The 1-, 3-, 5-, and 10-year survival rate was 77%, 22 %, 11%, and 10%, respectively.Conclusion: Size of primary tumor, the length of diseasefree interval, the number of lung metastases may provide additional information for predicting patients survival after treatment of lung metastases. Combination chemotherapy, especially DDP-based chemotherapy may prolong survival time of patients with lung metastases from breast cancer.

    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.

    Purpose: Evaluate the diagnostic performance of contrast enhanced CT/PET (ceCT/PET) in the response assessment of patients with colorectal cancer liver metastases. Methods: 33 ce CT/PET studies of 19 patients with colorectal liver metastases were prospectively evaluated. All of them, 13 (68.4%) were males and 6 (31.6%) females. Mean age and range were 63 [42–78]. All patients were treated with neoadjuvant chemotherapy. In all cases post-therapy diagnostic confirmation of liver lesions was obtained. A ce CT PET/was obtained 1 h after the injection of 370 MBq of 18F-FDG. Metabolic and morphologic studies were evaluated by two blinded nuclear physicians and radiologists respectively to assess the location, size and suspected diagnosis of lesions (benign or malignant). A combined assessment of both techniques was performed. The final diagnosis was established by histopathology or clinical/radiological follow-up greater than 6 months. Results: A total of 120 liver lesions were identified, 115 were malignant and 5 benign. From the malignant lesions, 105 were identified with the ceCT, 44 with the PET and 109 with ceCT/PET. All of the benign lesions were correctly classified with any of the three imaging techniques. The sensitivity of PET, ceCT and ceCT/PET were of 38%, 91% and 95% respectively and the specificity was 100% in all three of the diagnostic studies. Conclusion: Administration of intravenous contrast in the PET/CT is mandatory to evaluate treatment response rate of liver metastases due to the limitations of isolated metabolic images in these cases.

    Full Text Available Background. Metastasis is a crucial endpoint for patients with prostate cancer (PCa, but currently lacks a validated claims-based algorithm for detection. Objective. To develop an algorithm using ICD-9 codes to facilitate accurate reporting of PCa metastases. Methods. Medical records from 300 men hospitalized at Robert Wood Johnson University Hospital for PCa were reviewed. Using the presence of metastatic PCa on chart review as the gold standard, two algorithms to detect metastases were compared. Algorithm A used ICD-9 codes 198.5 (bone metastases, 197.0 (lung metastases, 197.7 (liver metastases, or 198.3 (brain and spinal cord metastases to detect metastases, while algorithm B used only 198.5. Sensitivity, specificity, positive predictive value (PPV, and negative predictive value (NPV for the two algorithms were determined. Kappa statistics were used to measure agreement rates between claim data and chart review. Results. Algorithm A demonstrated a sensitivity, specificity, PPV, and NPV of 95%, 100%, 100%, and 98.7%, respectively. Corresponding numbers for algorithm B were 90%, 100%, 100%, and 97.5%, respectively. The agreement rate is 96.8% for algorithm A and 93.5% for algorithm B. Conclusions. Using ICD-9 codes 198.5, 197.0, 197.7, or 198.3 in detecting the presence of PCa metastases offers a high sensitivity, specificity, PPV, and NPV value.

    Neuroendocrine tumors (NET) are extremely rare in children (0.75 cases per 100,000 children and adolescents a year) and the majority of these tumors are benign or present low grade of malignancy. According to the American registry Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute, less than 2% of all neuroendocrine tumors in children occur in the pancreas, making it a rare site for these tumors. The majority of them are found in children over 10years of age, especially those with malignant potential. Treatment of NET consists of different methods: surgery, somatostatin analogues and chemotherapy. Radical surgical resection remains the standard of treatment; however, it is not always feasible because of distant metastases. The authors present a case report of pancreatic NET with multiple metastases to the liver. The patient was treated with pancreatic resection and liver transplantation for liver metastases. Prior to liver transplantation, the patient was treated with somatostatin analogues, sunitinib and chemotherapy. Management of liver metastases with liver transplantation is discussed.

    The liver is the second only to lymph nodes as the most common site of metastatic disease irrespective of the primary tumor. Up to 50% of all patients with malignant diseases will develop liver metastases with a significant morbidity and mortality. Although the surgical resection leads to an improvement of the survival time, only approximately 20% of the patients are eligible for surgical intervention. Radiofrequency (RF) ablation represents one of the most important alternatives as well as complementary methods for the therapy of liver metastases. RF ablation can lead in a selected patient group to a palliation or to an increased life expectancy. RF ablation appears either safer (vs. cryotherapy) or easier (vs. laser) or more effective (percutaneous ethanol instillation [PEI]), transarterial chemoembolisation [TACE] in comparison with other minimal invasive procedures. RF ablation can be performed percutaneously, laparoscopically or intraoperatively and may be combined with chemotherapy as well as with surgical resection. Permanent technical improvements of RF systems, a better understanding of the underlying electrophysiological principles and an interdisciplinary approach will lead to a prognosis improvement in patients with liver metastases. (orig.) [German] Die Leber ist unabhaengig vom Primaertumor nach den Lymphknoten die zweithaeufigste Lokalisation von Metastasen.

    Background The recent advent of more effective chemotherapy and the development of surgical procedures have expanded the pool of resectable patients with colorectal liver metastases (CLM). Two-stage hepatectomy (TSH), associated liver partition and portal vein ligation for staged hepatectomy (ALPPS), and ultrasound-guided enhanced one-stage hepatectomy (e-OSH) are the surgical solutions proposed for these patients, but the range of indications for these procedures vary from institution to institution. Summary The advantages and disadvantages of each approach are herein discussed. Patients who drop out between the staged operations of TSH limit its success rate, although predictive scores may help with patient selection and thereby optimize the results. Safety and oncological suitability are concerns to be addressed when considering ALPPS. These concerns notwithstanding, ALPPS has introduced an innovative concept in surgery: the monosegmental remnant liver. Studies involving e-OSH have proven the oncological suitability of tumor exposure once the CLM is detached from major intrahepatic vessels. This finding could expand the indications for e-OSH, although the technical challenges that it entails limit its spread among the surgical community. The liver-first approach involves the clearance of tumors from the liver before the colorectal primary is tackled. This approach fully justifies the complexity of e-OSH. Key Messages Predictive scores limiting the interstage dropout of TSH, partial and monosegmental ALPPS, and R1 vascular e-OSH justified by solid long-term results represent new insights that could help refne the patient assignment to each of these approaches. Additionally, liver transplantation is an emerging treatment for CLM that should be taken into account. PMID:27995092

    Full Text Available Abstract Background Cancer of unknown primary site (CUP is considered an aggressive metastatic disease but whether the prognosis differs from metastatic cancers of known primary site is not known. Such data may give insight into the biology of CUP and the metastatic process in general. Methods 6,745 cancer patients, with primary metastatic cancer at diagnosis, were identified from the Swedish Cancer Registry, and were compared with 2,881 patients with CUP. Patients were diagnosed and died between 2002 and 2008. The influence of the primary site, known or unknown, on survival in patients with metastases at specific locations was investigated. Hazard ratios (HRs of death were estimated for several sites of metastasis, where patients with known primary sites were compared with CUP patients. Results Overall, patients with metastatic cancers with known primary sites had decreased hazards of death compared to CUP patients (HR = 0.69 [95% CI = 0.66–0.72]. The exceptions were cancer of the pancreas (1.71 [1.54–1.90], liver (1.58 [1.36–1.85], and stomach (1.16 [1.02–1.31]. For individual metastatic sites, patients with liver or bone metastases of known origin had better survival than those with CUP of the liver and bone. Patients with liver metastases of pancreatic origin had an increased risk of death compared with patients with CUP of the liver (1.25 [1.06–1.46]. The median survival time of CUP patients was three months. Conclusions Patients with CUP have poorer survival than patients with known primaries, except those with brain and respiratory system metastases. Of CUP sites, liver metastases had the worst prognosis. Survival in CUP was comparable to that in metastatic lung cancer. The aggressive behavior of CUP may be due to initial immunosuppression and immunoediting which may allow accumulation of mutations. Upon escape from the suppressed state an unstoppable tumor spread ensues. These novel data on the epidemiology of the

    The aim of this study was to compare a Gd-based nanoparticle (AGuIX) with a standard extracellular Gd-based contrast agent (Gd-DOTA) for MRI at 9.4 T in rats with hepatic colorectal cancer metastases. 12 rats with hepatic metastases were subjected to MRI using a 9.4 T animal scanner. T1w self-gated FLASH sequences (TR/TE=45/2.5 ms, alpha = 45 , TA=1: 23 min, FOV=5.12 x 5.12 cm{sup 2}, matrix = 256 x 256) were acquired before and at 10 time points after contrast injection. Each animal received 0.1 mmol/kg BW Gd-DOTA i.v. 2 days later AGuIX was applied at 0.01 mmol/kg BW (representing equal Gd doses). The SNR of normal liver (SNRliver), hyper- and hypoenhancing parts of tumors (SNRtumor, hyperenh/SNRtumor, hypoenhanc), erector spinae muscle (SNRmuscle), CNR and lesion enhancement (LE) were calculated based on ROI measurements. Mean SNRliver (Gd-DOTA: 14.6 ± 0.7; AGuIX: 28.2 ± 2.6, p < 0.001), SNRtumor, hyperenhanc (Gd-DOTA: 18.6 ± 1.2; AGuIX: 29.6 ± 2.8, p < 0.001), SNRtumor, hypoenhanc (Gd-DOTA: 12.0 ± 0.7; AGuIX: 15.4 ± 0.7, p < 0.001), SNRmuscle (Gd-DOTA: 12.3 ± 0.3; AGuIX: 14.0 ± 0.7, p < 0.001), mean CNR (Gd-DOTA: -2.5 ± 0.2; AGuIX: -7.5 ± 1.0, p < 0.001) and LE (Gd-DOTA: 3.8 ± 0.7; AGuIX: 14.9 ± 2.8, p=0.001) were significantly higher using AGuIX. Regardless of the larger molecular size, AGuIX demonstrates an early peak enhancement followed by a continuous washout. AGuIX provides better enhancement at 9.4 T compared to Gd-DOTA for equal doses of applied Gd. This is based on the molecule structure and the subsequent increased interaction with protons leading to a higher relaxivity. AGuIX potentially ameliorates the conspicuity of focal liver lesions and may improve the sensitivity in diagnostic imaging of malignant hepatic tumors.

    Background: Brain metastases (BM) are frequently diagnosed in patients with HER-2-positive metastatic breast cancer; in addition, an increasing incidence was reported for triple-negative tumours. We aimed to compare brain metastases free survival (BMFS) of breast cancer subtypes in patients treated between 1996 until 2010. Methods: Brain metastases free survival was measured as the interval from diagnosis of extracranial breast cancer metastases until diagnosis of BM. HER-2 status was analysed by immunohistochemistry and reanalysed by fluorescent in situ hybridisation if a score of 2+ was gained. Oestrogen-receptor (ER) and progesterone-receptor (PgR) status was analysed by immunohistochemistry. Brain metastases free survival curves were estimated with the Kaplan–Meier method and compared with the log-rank test. Results: Data of 213 patients (46 luminal/124 HER-2/43 triple-negative subtype) with BM from breast cancer were available for the analysis. Brain metastases free survival differed significantly between breast cancer subtypes. Median BMFS in triple-negative tumours was 14 months (95% CI: 11.34–16.66) compared with 18 months (95% CI: 14.46–21.54) in HER-2-positive tumours (P=0.001) and 34 months (95% CI: 23.71–44.29) in luminal tumours (P=0.001), respectively. In HER-2-positive patients, co-positivity for ER and HER-2 prolonged BMFS (26 vs 15 m; P=0.033); in luminal tumours, co-expression of ER and PgR was not significantly associated with BMFS. Brain metastases free survival in patients with lung metastases was significantly shorter (17 vs 21 months; P=0.014). Conclusion: Brain metastases free survival in triple-negative breast cancer, as well as in HER-2-positive/ER-negative, is significantly shorter compared with HER-2/ER co-positive or luminal tumours, mirroring the aggressiveness of these breast cancer subtypes.

    BACKGROUND: Hepatoid tumors (HTs) are rare extra-hepatic neoplasms with the histological features, biochemical proifle and, sometimes, even clinical course of hepatocellular carcinoma. We present a case of rectal hepatoid adenocarcinoma with metachronous liver metastases. METHODS: Four months after total procto-colectomy for a rectal adenocarcinoma (Astler-Coller C2), a 42-year-old man with ulcerative colitis showed hypoechoic masses in the hepatic parenchyma by abdominal ultrasonography. Carcinoembryonic antigen was normal, but alpha-fetoprotein was 32 000 μg/L. Fine-needle biopsy revealed that liver masses were positive for hepatocellular carcinoma. The patient underwent left hepatectomy and alcoholisation of a small deep nodule in segment 8. RESULTS:  Immunohistochemistry and albumin mRNA in situ hybridization suggested that the nodules were metastases of a HT. The patient was well during the ifrst 6 months and refused any adjuvant chemotherapy. He died from liver failure 19 months after initial diagnosis. CONCLUSIONS: HT is a rare colon cancer. The preoperative diagnosis of this tumor requires a high degree of suspicion, the availability of a panel of immunohistochemical markers, and a certain amount of luck. The prognosis is poor despite an aggressive and multimodal therapeutic strategy. So far, none of the hypotheses proposed about the origin and the biology of these tumors is convincing.

    Small bowel (SBNETs) and pancreatic neuroendocrine tumors (PNETs) often present with liver metastases. Although liver biopsy establishes a neuroendocrine diagnosis, the primary tumor site is frequently unknown without exploratory surgery. Gene expression differences in metastases may distinguish primary SBNETs and PNETs. This study sought to determine expression differences of four genes in neuroendocrine metastases and to create a gene expression algorithm to distinguish the primary site. Nodal and liver metastases from SBNETs and PNETs (n = 136) were collected at surgery under an Institutional Review Board-approved protocol. Quantitative PCR measured expression of bombesin-like receptor-3, opioid receptor kappa-1, oxytocin receptor, and secretin receptor in metastases. Logistic regression models defined an algorithm predicting the primary tumor site. Models were developed on a training set of 21 nodal metastases and performance was validated on an independent set of nodal and liver metastases. Expression of all four genes was significantly different in SBNET compared to PNET metastases. The optimal model employed expression of bombesin-like receptor-3 and opioid receptor kappa-1. When these genes did not amplify, the algorithm used oxytocin receptor and secretin receptor expression, which allowed classification of all 136 metastases with 94.1 % accuracy. In the independent liver metastasis validation set, 52/56 (92.9 %) were correctly classified. Positive predictive values were 92.5 % for SBNETs and 93.8 % for PNETs. This validated algorithm accurately distinguishes SBNET and PNET metastases based on their expression of four genes. High accuracy in liver metastases demonstrates applicability to the clinical setting. Studies assessing this algorithm's utility in prospective clinical decision-making are warranted.

  17. Update on the optimal management of patients with colorectal liver metastases.

    2012-10-01

    Patients with colorectal liver metastases represent a distinct subset of metastatic colorectal cancer. Optimal management requires a multidisciplinary approach, local and systemic. Curative hepatic surgery is standard for resectable cases, but unfortunately, the majority of patients are not initially resectable due to the size, location, and/or extent of disease, inadequate remnant liver volume, or comorbidities. Other local approaches may be complementary (such as portal vein embolization) or alternative (such as ablation, hepatic arterial infusion, selective internal radiation therapy, and stereotactic body radiotherapy) to surgery. Systemic therapy can downsize disease, allowing surgical resection and, potentially, long-term survival, but it must be balanced against the potential for hepatotoxicity. Current standard approaches including cytotoxics and biologics, such as bevacizumab and particularly anti-epidermal growth factor receptor therapy, improve response rates and may enhance downsizing and resection rates. Optimization of local therapies and systemic conversion strategies via controlled, randomized trials is still a pending question.

    Background. Stereotactic radiation therapy is an evolving modality to treat otherwise unresectable liver metastases. In this analysis, two local therapies: 1) single session robotic radiosurgery (RRS) and 2) percutaneous radiofrequency ablation (RFA) were compared in a total of 60 heavily pretreated colorectal cancer patients. Methods. Thirty patients with a total of 35 colorectal liver metastases not qualifying for surgery that were treated in curative intent with RRS were prospectively followed. To compare efficacy of both treatment modalities, patients treated with RFA during the same period of time were matched according to number and size of the treated lesions. Local tumor control, local disease free survival (DFS), and freedom from distant recurrence (FFDR) were analyzed for effi cacy. Treatment-related side effects were recorded for comparison. Results. The median diameter of the treated lesions was 33 mm (7-53 mm). Baseline characteristics did not differ significantly between the groups. One- and two-year local control rates showed no signifi cant difference but favored RRS (85% vs. 65% and 80% vs. 61%, respectively). A signifi cantly longer local DFS of patients treated with RRS compared to RFA (34.4 months vs. 6.0 months; p 0.001) was found. Both, median FFDR (11.4 months for RRS vs. 7.1 months for RFA p=0.25) and the recurrence rate (67% for RRS and 63% for RFA, p>0.99) were comparable. Conclusion. Single session RRS is a safe and effective method to treat colorectal liver metastases. In this analysis, a trend towards longer DFS was seen in patients treated with RRS when compared to RFA.

    Unresectable liver metastases of colorectal cancer can be treated with systemic chemotherapy, aiming to limit the disease, extend survival or turn unresectable metastases into resectable ones. Some patients however, suffer from side effects or progression under systemic treatment. For patients with metastasized uveal melanoma there are no standard systemic therapy options. For patients without extrahepatic disease, isolated liver perfusion (IHP) may enable local disease control with limited systemic side effects. Previously, this was performed during open surgery with satisfying results, but morbidity and mortality related to the open procedure, prohibited a widespread application. Therefore, percutaneous hepatic perfusion (PHP) with simultaneous chemofiltration was developed. Besides decreasing morbidity and mortality, this procedure can be repeated, hopefully leading to a higher response rate and improved survival (by local control of disease). During PHP, catheters are placed in the proper hepatic artery, to infuse the chemotherapeutic agent, and in the inferior caval vein to aspirate the chemosaturated blood returning through the hepatic veins. The caval vein catheter is a double balloon catheter that prohibits leakage into the systemic circulation. The blood returning from the hepatic veins is aspirated through the catheter fenestrations and then perfused through an extra-corporeal filtration system. After filtration, the blood is returned to the patient by a third catheter in the right internal jugular vein. During PHP a high dose of melphalan is infused into the liver, which is toxic and would lead to life threatening complications when administered systemically. Because of the significant hemodynamic instability resulting from the combination of caval vein occlusion and chemofiltration, hemodynamic monitoring and hemodynamic support is of paramount importance during this complex procedure.

    Colorectal cancer (CRC) is a common malignant disease and the severe nature of cases in men and women who develop colorectal cancer makes this an important socio-economic health issue. Major challenges such as understanding and modeling colorectal cancer pathways rely on our understanding of simple models such as outlined in this paper. We discuss that the development of novel standardized approaches of multidimensional (correlative) biomolecular microscopy methods facilitates the collection of (sub) cellular tissue information in the early onset of colorectal liver metastasis and that this approach will be crucial in designing new effective strategies for CRC treatment. The application of X-ray micro-computed tomography and its potential in correlative imaging of the liver vasculature will be discussed.

  2. Can the National Health Service Cancer Plan timeline be applied to colorectal hepatic metastases?

    2012-02-01

    INTRODUCTION: The National Health Service (NHS) Cancer Plan guidelines recommend a maximum 2-week wait from referral to first appointment, and 2 months from referral to treatment for primary cancers. However, there are currently no guidelines available for metastatic disease. In the UK, nearly half of all colorectal cancer patients develop hepatic metastases. Timely, surgical resection offers the potential for cure. The aim of this study was to audit current practice for colorectal liver metastases in a regional hepatobiliary unit, and compare this to the NHS Cancer Plan standards for primary disease. PATIENTS AND METHODS: A retrospective review of the unit\\'s database was performed for all hepatic metastases referrals from January 2006 to December 2008. The dates of referral, first appointment, investigations and initiation of treatment, along with patient\\'s age and sex, were recorded on Microsoft Excel and analysed. Time was expressed as mean +\\/- SD in days. RESULTS: A total of 102 patients with hepatic metastases were identified. Five were excluded due to incomplete data. The average time from referral to first appointment was 10.6 +\\/- 9.4 days and the average time from referral to treatment was 38.5 +\\/- 28.6 days. Seventy-five (72.7%) had surgical intervention, of whom 37 also had chemotherapy. CONCLUSIONS: The data compare favourably to the NHS Cancer Plan guidelines for primary malignancy, demonstrating that a regional hepatobiliary unit is capable of delivering a service for colorectal liver metastases that adheres to the NHS Cancer Plan. Therefore, the NHS Cancer Plan can be applied to this cohort.

    Lymph node metastases are important determinants in the prognosis of primary colorectal cancer. Although it has been established that enlarged, palpable lymph nodes contain metastases in less than half of the cases, no definitive data concerning the incidence of metastases in lymph nodes measuring 5 mm or less are available. We treated the surgical specimens of 52 consecutive patients who had colon cancer with a lymph node clearance technique at the Roswell Park Memorial Institute, Buffalo. We found 2699 lymph nodes in the 52 specimens, with a mean of 52 lymph nodes per specimen (range, five to 151). Sixty-four lymph nodes were found with metastases in 21 (40%) of the 52 patients. Fifty-nine of 64 of the lymph nodes were reexamined and remeasured. Thirty-nine lymph node metastases measured less than 5 mm, 13 were between 5 and 10 mm, and eight were larger than 10 mm. We concluded that lymph node metastases in colon cancer occur most frequently in lymph nodes measuring less than 5 mm (small lymph nodes). The use of lymph node clearing techniques in surgical specimens improves detection of small lymph node metastases and thereby diminishes understaging.

    A 64-year-old man was admitted to the Sun Yat-Sen University Cancer Center with chief complaints of recurrent abdominal pain and diarrhea for about 3 years and with a history of surgical repair for intestinal perforation owing to stress ulcer. Positron emission tomography (PET)/computed tomography (CT) demonstrated a primary tumor on the pancreatic tail with multifocal liver metastases. Pathological and immunohistochemistry staining revealed the lesion to be a pancreatic neuroendocrine tumor (pNET). According to the latest World Health Organization (WHO, 2013) classification, the tumor was classified as stage IV functional G1 pNET. After referral to the multidisciplinary treatment board (MDT), the patient was started on periodic dose of omeprazole, somatostatin analogues and Interferon α (IFNα) and had scanning follow-ups. Based upon the imaging results, CT-guided radioactive iodine-125 ((125)I) seeds implantation therapy, radiofrequency ablation therapy (RFA) or microwave ablation technique were chosen for the treatment of the primary tumor. Transarterial chemoembolization (TACE), RFA and microwave ablation techniques were decided upon for liver metastases. The patient showed beneficial response to the treatment with clinically manageable low-grade side effects and attained partial remission (RECIST criteria) with a good quality of life.

    In order to discuss the role of preoperative chemotherapy for colorectal liver metastases, which is used frequently before hepatic resection, even in patients with resectable disease at presentation, we herein report the development of two complications, partial portal vein thrombosis and hepatic steatosis with lobular inflammation, during the course of preoperative chemotherapy with FOLFIRI plus bevacizumab for colorectal liver metastases, which recognition led to timely discontinuation of chemotherapy as well as a change in the surgical strategy to resect the tumors and the damaged liver through advanced techniques.We conclude that duration of treatment and drug doses and combinations may impact the development of chemotherapy-induced liver injury. Surgeons and medical oncologists must work together to devise safe, rational,and oncologically appropriate treatments for patients with multiple colorectal liver metastases, and to improve the understanding of the pathogenesis of chemotherapyinduced liver injury.

    Full Text Available Treatment results of low rectal cancer patient with internal sphincter involvement and synchronous liver metastases is presented. After combined treatment including preoperative targeted therapy, chemotherapy, chemoradiotherapy a synchronous resection of primary tumour and liver metastases was carried out (R0. Synchronous right hepihepatectomy and proctectomy was performed with resection of the deep part of external sphincter, neorectum creation by transverse coloplasty, neoanal sphincter creation using colonic smooth muscle layer without preventive colostomy. A possibility of synchronous plastic sphincter-sparing surgery in metastatic rectal cancer patient with locally advanced tumour is demonstrated. Such treatment allows to remove the risk of primary tumour complications, facilitates further chemotherapy treatment and improves quality of life and long-term treatment outcome.

    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.

    Full Text Available Primary tumor excision is one of the therapies of cancer most widely used. However, the risk of metastases development still exists following tumor resection. The liver is a common site of metastatic disease for numerous cancers. Breast cancer is one of the most frequent source of metastases to the liver. The aim of this work was to evaluate the efficacy of the orally-administered Salmonella Typhi vaccine strain CVD 915 on the development of liver metastases in a mouse model of breast cancer. To this end, one group of BALB/c mice was immunized with CVD 915 via o.g. while another received PBS as a control. After 24 h, mice were injected with LM3 mammary adenocarcinoma cells into the spleen and subjected to splenectomy. This oral Salmonella-based vaccine produced an antitumor effect, leading to a decrease in the number and volume of liver metastases. Immunization with Salmonella induced an early cellular immune response in mice. This innate stimulation rendered a large production of IFN-γ by intrahepatic immune cells (IHIC detected within 24 h. An antitumor adaptive immunity was found in the liver and celiac & portal lymph nodes (LDLN 21 days after oral bacterial inoculation. The antitumor immune response inside the liver was associated with increased CD4+ and DC cell populations as well as with an inflammatory infiltrate located around liver metastatic nodules. Enlarged levels of inflammatory cytokines (IFN-γ and TNF were also detected in IHIC. Furthermore, a tumor-specific production of IFN-γ and TNF as well as tumor-specific IFN-γ-producing CD8 T cells (CD8+IFN-γ+ were found in the celiac & portal lymph nodes of Salmonella-treated mice. This study provides first evidence for the involvement of LDLN in the development of an efficient cellular immune response against hepatic tumors, which resulted in the elimination of liver metastases after oral Salmonella-based vaccination.

    2013-09-01

    Full Text Available In breast cancer patients, bone is the most common site of metastases. Medical therapies are the basic therapy to prevent distant metastases and recurrence and to cure them. Radiotherapy has a primary role in pain relief, recalcification and stabilization of the bone, as well as the reduction of the risk of complications (e.g., bone fractures, spinal cord compression. Bisphosphonates, as potent inhibitors of osteoclastic-mediated bone resorption are a well-established, standard-of-care treatment option to reduce the frequency, severity and time of onset of the skeletal related events in breast cancer patients with bone metastases. Moreover bisphosphonates prevent cancer treatment-induced bone loss. Recent data shows the anti-tumor activity of bisphosphonates, in particular, in postmenopausal women and in older premenopausal women with hormone-sensitive disease treated with ovarian suppression. Pain is the most frequent symptom reported in patients with bone metastases, and its prevention and treatment must be considered at any stage of the disease. The prevention and treatment of bone metastases in breast cancer must consider an integrated multidisciplinary approach.

    Leptomeningeal disease (LMD) is a highly aggressive and usually rapidly fatal condition. The purpose of this study is to identify clinical factors that can serve to predict for LMD at the time of stereotactic radiosurgery (SRS) for brain metastases from breast carcinoma. We conducted a retrospective review of patients with brain metastases from breast cancer treated with SRS from 1995 to 2014 at our institution. Clinical, radiographic, and dosimetric data were collected. LMD was diagnosed by cerebrospinal fluid (CSF) cytology or MRI demonstrating CSF seeding. Comparative statistical analyses were conducted using Cox proportional hazards regression, binary logistic regression, and/or log-rank test. 126 patients met inclusion criteria. Eighteen patients (14 %) developed LMD following SRS. From the time of SRS, the actuarial rate of LMD at 12 months from diagnosis of brain metastasis was 9 % (11 patients). Active disease in the chest at the time of SRS was associated with development of LMD (p = 0.038). Factors including receptor status, tumor size, number of intra-axial tumors, cystic tumor morphology, prior WBRT, active bone metastases, and active liver metastases were not significantly associated with the development of LMD. In patients with brain metastasis from breast cancer that undergo SRS, there is a relatively low rate of LMD. We found that while tumor hormonal status, bone metastases, and hepatic metastases were not associated with the development of LMD, active lung metastases at SRS was associated with LMD. Further research may help to delineate a causative relationship between metastatic lung disease and LMD.

    AIM: To explore the oncological outcomes of unresectable lung metastases without extrapulmonary metastases in colorectal cancer. METHODS: Patients with unresectable isolated lung metastases from colorectal cancer were prospectively collected in a single institution during a 5-year period. All patients received either the fluorouracil/leucovorin plus oxaliplatin, fluorouracil/leucovorin plus irinotecan or capecitabine plus oxaliplatin regimen as first-line treatment. The resectability after preoperative chemotherapy was evaluated. Patients’ outcome and predictive factors for overall survival were also investigated by univariate and multivariate analysis. RESULTS: A total of 70 patients were included in the study. After standardized first-line chemotherapy, only 4 patients (5.7%) were converted to resectable disease. The median overall survival time in all patients was 19 mo (95% CI: 12.6-25.4), with a 2-year overall survival rate of 38.8%. No survival difference was found among different first-line chemotherapeutic regimens. Prognostic analysis demonstrated that only the first response assessment for first-line treatment was the independent factor for predicting overall survival. The median survival time in partial response, stable disease and progressive disease patients were 27 mo, 16 mo and 8 mo (P = 0.00001). CONCLUSION: Pulmonary metastasectomy can only be performed in a small part of unresectable lung metastases patients after chemotherapy. Patients’ first response assessment is an important prognostic factor. PMID:20614489

    Introduction. Colorectal cancer is one of the most frequent cancers in the world and liver metastases are seen in up to 19% of patients with colorectal cancers. Detection of liver metastases is not only vital for sufficient treatment and survival, but also for a better estimation of prognosis....... The aim of this study was to evaluate the feasibility of diffusion weighted MRI of the liver as part of a combined MR evaluation of patients with rectal cancers and compare it with the standard preoperative evaluation of the liver with CT. Methods. Consecutive patients diagnosed with rectal cancers were....... The current standard preoperative evaluation with CT-scan results in disadvantages like missed metastases and futile operations. We recommend that patients with rectal cancer, who are scheduled for MR of the rectum, should have a DWMR of the liver performed at the same time....

    Proteoglycans are a group of molecules that contain at least one glycosaminoglycan chain, such as a heparan, dermatan, chondroitin, or keratan sulfate, covalently attached to the protein core. These molecules are categorized based on their structure, localization, and function, and can be found in the extracellular matrix, on the cell surface, and in the cytoplasm. Cell-surface heparan sulfate proteoglycans, such as syndecans, are the primary type present in healthy liver tissue. However, deterioration of the liver results in overproduction of other proteoglycan types. The purpose of this article is to provide a current summary of the most relevant data implicating proteoglycans in the development and progression of human and experimental liver cancer. A review of our work and other studies in the literature indicate that deterioration of liver function is accompanied by an increase in the amount of chondroitin sulfate proteoglycans. The alteration of proteoglycan composition interferes with the physiologic function of the liver on several levels. This article details and discusses the roles of syndecan-1, glypicans, agrin, perlecan, collagen XVIII/endostatin, endocan, serglycin, decorin, biglycan, asporin, fibromodulin, lumican, and versican in liver function. Specifically, glypicans, agrin, and versican play significant roles in the development of liver cancer. Conversely, the presence of decorin could potentially provide protective effects.

    BACKGROUND: Uveal melanoma is the most common primary intraocular malignancy in adults. Despite successful control of the primary tumor, metastatic disease will ultimately develop in approximately 50% of patients, with the liver being the most common site for metastases. The median survival...... for patients with liver metastases is between 6 and 12 months, and no treatment has in randomized trials ever been shown to prolong survival. A previous phase II trial using isolated hepatic perfusion (IHP) has suggested a 14-month increase in overall survival compared with a historic control group consisting...... of the longest surviving patients in Sweden during the same time period (26 versus 12 months). METHODS/DESIGN: This is the protocol for a multicenter phase III trial randomizing patients with isolated liver metastases of uveal melanoma to IHP or best alternative care (BAC).

    Full Text Available OBJECTIVE: To investigate clinical and laboratory toxicity in patients with unresectable liver metastases, treated with yttrium-90 radioembolization ((90Y-RE. METHODS: Patients with liver metastases treated with (90Y-RE, between February 1(st 2009 and March 31(st 2012, were included in this study. Clinical toxicity assessment was based on the reporting in patient's charts. Laboratory investigations at baseline and during a four-month follow-up were used to assess laboratory toxicity according to the Common Terminology Criteria for Adverse Events version 4.02. The occurrence of grade 3-4 laboratory toxicity was stratified according to treatment strategy (whole liver treatment in one session versus sequential sessions. Response assessment was performed at the level of target lesions, whole liver and overall response in accordance with RECIST 1.1 at 3- and 6 months post-treatment. Median time to progression (TTP and overall survival were calculated by Kaplan-Meier analysis. RESULTS: A total of 59 patients, with liver metastases from colorectal cancer (n = 30, neuroendocrine tumors (NET (n = 6 and other primary tumors (n = 23 were included. Clinical toxicity after (90Y-RE treatment was confined to grade 1-2 events, predominantly post-embolization symptoms. No grade 3-4 clinical toxicity was observed, whereas laboratory toxicity grade 3-4 was observed in 38% of patients. Whole liver treatment in one session was not associated with increased laboratory toxicity. Three-months disease control rates for target lesions, whole liver and overall response were 35%, 21% and 19% respectively. Median TTP was 6.2 months for target lesions, 3.3 months for the whole liver and 3.0 months for overall response. Median overall survival was 8.9 months. CONCLUSION: The risk of severe complications or grade 3-4 clinical toxicity in patients with liver metastases of various primary tumors undergoing (90Y-RE is low. In contrast, laboratory toxicity grade 3

  11. Imatinib mesylate induces responses in patients with liver metastases from gastrointestinal stromal tumor failing intra-arterial hepatic chemotherapy

    2006-01-01

    Full Text Available Background: Imatinib mesylate represents a real major paradigm shift in cancer therapy, targeting the specific molecular abnormalities, crucial in the etiology of tumor. Intra-arterial hepatic chemotherapy (IAHC followed by embolization, has been considered an interesting palliative option for patients with liver metastases from gastrointestinal stromal tumor (GIST, due to the typically hypervascular pattern of the tumor. Aims: We report our experience with IAHC followed by Imatinib mesylate, in order to show the superiority of the specific molecular approach in liver metastases from GIST. Materials and Methods: Three patients (pts with pretreated massive liver metastases from GIST, received IAHC with Epirubicin 50 mg/mq, every 3 weeks for 6 cycles. At the evidence of progression, they received Imatinib mesylate. Results: We observed progressive diseases in all cases. In 1998, one patient underwent Thalidomide at 150 mg orally, every day for 4 months, with evidence of stable disease and clinical improvement. In 2001, two patients received Imatinib mesylate at 400 mg orally, every day, with evidence of partial response lasting 18+ months and 16 months. One of them had grade 3 neutropenia, with suspension of therapy for 3 weeks. Conclusion: No patient treated with IAHC, reported objective responses, but two of them obtained partial response after the assumption of Imatinib mesylate and one showed temporary stabilization with thalidomide. Imatinib mesylate represents a new opportunity in GIST therapy, targeting the specific molecular alteration. It seems to be superior to conventional intra arterial hepatic chemotherapy.

    The liver is the most common site of metastatic tumour deposits. Hepatic metastases are the major cause of morbidity and mortality in patients with gastrointestinal carcinomas and other malignant tumours. The rationale and results for interventional therapeutic techniques in the treatment of liver metastases are presented. For the treatment of patients with irresectable liver metastases, alternative local ablative therapeutic modalities have been developed. Technique and results of local interventional therapies are presented such as microwave-, radiofrequency (RF)- and ultrasound ablation, and laser-induced interstitial therapy (LITT), cryotherapy and local drug administration such as alcohol injection, endotumoral chemotherapy and regional chemoembolisation. In addition to cryotherapy, all ablative techniques can be performed percutaneously with low morbidity and mortality. Cryotherapy is an effective and precise technique for inducing tumour necrosis, but it is currently performed via laparotomy. Percutaneous local alcohol injection results in an inhomogeneous distribution in liver metastases with unreliable control rates. Local chemotherapeutic drug instillation and regional chemoembolisation produces relevant but non-reproducible lesions. Laser-induced interstitial thermotherapy (LITT) performed under MRI guidance results in precise and reproducible areas of induced necrosis with a local control of 94 %, and with an improved survival rate. Interventional therapeutic techniques of liver metastases do result in a remarkable local tumour control rate with improved survival results. (orig.) With 5 figs., 1 tab., 43 refs.

  13. Safety of Redo Hepatectomy for Colorectal Liver Metastases after Selective Interarterial Radiation Therapy: A Case Report

    2014-01-01

    Full Text Available Surgical resection is the only potentially curative strategy in the treatment of patients with colorectal liver metastases (CLM. Unfortunately, only about 10%–15% of patients are candidates for resection. Preoperative chemotherapy aims to increase the number of patients that may be eligible for liver resection by downsizing liver metastases. For patients with unresectable, chemotherapy refractory CLM the available treatment options are limited. Selective interarterial radiation therapy (SIRT is one of the most promising treatment options for this group of patients. Although only a small number of these patients have been reported as becoming candidates for potentially curative hepatic resection following sufficient reduction in the volume of liver metastases, the question arises regarding the safety of liver resection in these patients. We report a case of a patient who presented unresectable liver relapse of CLM after previous right hepatectomy. He underwent SIRT which resulted in downsizing of the liver metastases making the patient candidate for left lateral sectionectomy. He underwent the redo hepatectomy without any complications. To the best of our knowledge, this is the first reported case of redo hepatectomy after SIRT for CLM.

    Full Text Available Osteopoikilosis is a rare benign osteosclerotic bone disorder that may be misdiagnosed as skeletal metastases. Here we describe a case of coincidental breast cancer and osteopoikilosis mimicking skeletal metastases. A 41-year-old woman underwent right modified radical mastectomy in April 2007. Twenty-eight months after initial treatment,the patient complained of bilateral knee and foot pain. Plain X-rays of the feet and knees showed multiple well-defined osteosclerotic lesions. According to the radiographic appearance, the most likely differential diagnoses included skeletal metastases from breast cancer and osteopoikilosis. A whole-body bone scintigraphy showed no increase in uptake by the sclerotic lesions, and serum lactic dehydrogenase, carcinoembryonic antigen, alkaline phosphatase and cancer antigen 15-3 were not elevated. We therefore diagnosed the patient’s skeletal lesions as osteopoikilosis. This case and ourliterature review suggest that the radiographic appearance of osteopoikilosis may mimic or mask skeletal metastases, potentially leading to misdiagnosis in patients with cancer.

  17. DNA Copy Number Changes at 8q11–24 in Metastasized Colorectal Cancer

    Directory of Open Access Journals (Sweden)

    T. E. Buffart

    2005-01-01

    Full Text Available Background: C-Myc, a well-known oncogene located on 8q24.12–q24.23, is often amplified and over-expressed in both primary and metastasizing colorectal cancer. In addition, PRL-3 (also known as PTP4A3, a tyrosine phosphatase located on 8q24.3, is amplified in colorectal cancer metastasis. Beside PRL-3 and c-myc, other oncogenes located on the 8q23–24 region might be involved in this process. Therefore, the present study aims to correlate DNA copy number status of a series of genes at 8q23–24 in colorectal cancer at high resolution in correlation to metastatic disease. Materials and Methods: Thirty-two cases of colorectal cancer, 10 stage B1, 10 B2 and 12 D (Astler–Coller with their corresponding liver metastasis and one colorectal cell line (colo205, previously analyzed by array-CGH, were included in this study. A chromosome 8 specific MLPA probe mixture was used to analyze the presence of DNA copy number changes. The probe mixture contained 29 probes covering 25 genes on chromosome 8, as well as 6 control probes on other chromosomes. Results and Discussion: MLPA results obtained of the colo205 colorectal cell line were comparable with previous array-CGH results, thus validating the MLPA probe mixture. Astler–Coller B1 and B2 colorectal cancers differed significantly in DNA copy number of the genes, MOS (p = 0.04, MYC (p = 0.007, DDEF1 (p = 0.004, PTK2 (p = 0.02 and PTP4A3 (p = 0.04. When comparing these with Astler–Coller D primary tumors, significant differences were seen for several genes as well (MYC (p < 0.000, DDEF1 (p < 0.000, SLA (p < 0.000, PTK2 (p < 0.000, PTP4A3 (p = 0.002, and RECQL4 (p = 0.01. When comparing primary Astler–Coller D tumors and their corresponding liver metastases, a similar pattern of gains and losses was observed. Most of the liver metastases showed higher DNA copy number ratios than the corresponding primary tumors, but this difference was only significant for TPD52 (p = 0.02 and EIF3S6 (p = 0

    Background Over 50% of patients with colorectal cancer will develop liver metastases. Only a minority of patients present with technically resectable disease. Around 40% of those undergoing surgical resection are alive five years after their diagnosis compared with less than 1% for those with disseminated disease treated with systemic chemotherapy. Surgical resection remains the only possibility for long-term survival for these patients and great efforts have been made to increase the rates of resection whilst improving long-term outcomes. Summary This review considers current technical and oncological criteria for resection, as well as targeted approaches to stratify underlying tumor biology in order to better predict long-term benefit. The role of neoadjuvant and perioperative systemic chemotherapy is critically reviewed, with suggestions for patient stratification in order to identify those who are likely to derive the greatest benefit. The key role of multidisciplinary assessment and decision making for these complex patients is also discussed. Key Messages Surgery remains the optimal treatment for colorectal liver metastases (CRLM). Despite the curative intent of surgical resection, the majority of patients develop recurrence. Surgical strategies should therefore be adopted to maximize the potential for repeat resections in the event of recurrence. Although a number of preoperative prognostic markers have been identified, none are absolute contraindications to resection. In order to reduce postoperative recurrence, neo-adjuvant chemotherapy is now the standard of care in a number of countries. The evidence base for this approach is contentious, and the potential benefit of such a strategy is likely to be greatest in patients with high oncological risk disease. Multidisciplinary care is essential to ensure the optimal management of these complex patients. In addition, all patients with CRLM should be discussed with specialist hepatobiliary surgeons. PMID

    Few clinical studies have demonstrated an anti-proliferative activity of somatostatin (SST) analogs in carcinoids. We report the case of a woman with liver metastases of neuroendocrine tumor and no evidence of the primary tumor. The liver metastases were characterized by high proliferation indes, immunoreactiviy for somatostatin receptor (SSTR) -1,2,3 and 5and positive octreoscan. Urinary 5-hydrozyindolacetic acid, serum serotonin and chromogranin A were elevated. Slow release lanretoide (SR-LAN) therapy for 3 mo controlled clinical and biochemical signs of carcinoid tumor and caused a clear-cut reduction in the diameter of two liver metastases and disappearance of another lesion, with further reduction after 6 and 18 mo. We demonstrated a Clear-cut long-lasting antioccult carcinoid with high proliferation index and immunoreactivity for SSTR-1,2,3, and 5. Immunohistochemistry for SSTRs could be a suitable method for the selection of patients with metasatic carcinoid that may benefit from SST analog therapy.

    Abstract We previously demonstrated the therapeutic efficacy of different boron neutron capture therapy (BNCT) protocols in an experimental model of oral cancer. BNCT is based on the selective accumulation of 10B carriers in a tumor followed by neutron irradiation. Within the context of exploring the potential therapeutic efficacy of BNCT for the treatment of liver metastases, the aim of the present study was to perform boron biodistribution studies in an experimental model of liver metastases in rats. Different boron compounds and administration conditions were assayed to determine which administration protocols would potentially be therapeutically useful in in vivo BNCT studies at the RA-3 nuclear reactor. A total of 70 BDIX rats were inoculated in the liver with syngeneic colon cancer cells DHD/K12/TRb to induce the development of subcapsular tumor nodules. Fourteen days post-inoculation, the animals were used for biodistribution studies. We evaluated a total of 11 administration protocols for the boron compounds boronophenylalanine (BPA) and GB-10 (Na210B10H10), alone or combined at different dose levels and employing different administration routes. Tumor, normal tissue, and blood samples were processed for boron measurement by atomic emission spectroscopy. Six protocols proved potentially useful for BNCT studies in terms of absolute boron concentration in tumor and preferential uptake of boron by tumor tissue. Boron concentration values in tumor and normal tissues in the liver metastases model show it would be feasible to reach therapeutic BNCT doses in tumor without exceeding radiotolerance in normal tissue at the thermal neutron facility at RA-3.

    Purpose: To present long-term outcomes on the safety and efficacy of Yttrium-90 radioembolization in the treatment of unresectable hepatic neuroendocrine metastases refractory to standard-of-care therapy. Methods and Materials: This study was approved by our institutional review board and was compliant with the Health Insurance Portability and Accountability Act. Forty patients with hepatic neuroendocrine metastases were treated with {sup 90}Y radioembolization at a single center. Toxicity was assessed using National Cancer Institute Common Terminology Criteria v3.0. Response to therapy was assessed by World Health Organization (WHO) guidelines for size and European Association for the Study of the Liver disease (EASL) guidelines for necrosis. Time to response and overall survival were calculated using the Kaplan-Meier method. Univariate and multivariate analyses were performed. Results: The median dose was 113 Gy (29-299 Gy). Clinical toxicities included fatigue (63%), nausea/vomiting (40%), abdominal pain (18%), fever (8%), diarrhea and weight loss (5%); Grade 3 and 4 bilirubin toxicities were experienced by 2 patients and 1 patient, respectively. Different responses were noted by WHO (complete response, 1.2%; partial response, 62.7%) and EASL (complete response, 20.5%; partial response, 43.4%). Median time to response was 4 and 4.9 months by lesion and patient, respectively. The 1-, 2-, and 3-year overall survival rates were 72.5%, 62.5%, and 45%, respectively. Eastern Cooperative Oncology Group (ECOG) performance score 0 (p < 0.0001), tumor burden {<=}25% (p = 0.0019), albumin {>=}3.5 g/dL (p = 0.017), and bilirubin {<=}1.2 mg/dL (p = 0.002) prognosticated survival on univariate analysis; only ECOG performance score 0 and bilirubin {<=}1.2 mg/dL prognosticated better survival outcome on multivariate analysis (p = 0.0001 and p = 0.02). Conclusion: Yttrium-90 therapy for hepatic neuroendocrine metastases leads to satisfactory tumor response and patient survival

    2006-06-01

    Full Text Available Abstract Background Neuroendocrine tumours frequently metastasize to the liver. Although generally slowly progressing, hepatic metastases are the major cause of carcinoid syndrome and ultimately lead to liver dysfunction, cardiac insufficiency and finally death. Methods A literature review was performed to define the optimal treatment strategy and work-up in patients with neuroendocrine hepatic metastases. Based on this, an algorithm for the management of these patients was established. Results Platelet serotonin and chromogranin A are useful biomarkers for detection and follow-up of neuroendocrine tumour. Helical computed tomography and somatostatin receptor scintigraphy are the most sensitive diagnostic modalities. Surgical debulking is an accepted approach for reducing hormonal symptoms and to establish better conditions for medical treatment, but is frequently impossible due to the extent of disease. A novel approach is the local ablation of tumour by thermal coagulation using therapies such as radiofrequency ablation (RFA or laser induced thermotherapy (LITT. These techniques preserve normal liver tissue. There is a tendency to destroy metastases early in the course of disease, thereby postponing or eliminating the surgically untreatable stage. This can be combined with postoperative radioactive octreotide to eliminate small multiple metastases. In patients with extensive metastases who are not suitable for local destruction, systemic therapy by octreotide, 131I-MIBG treatment or targeted chemo- and radiotherapy should be attempted. A final option for selective patients is orthotopic liver transplantation. Conclusion Treatment for patients with neuroendocrine hepatic metastases must be tailored for each individual patient. When local ablative therapies are used early in the course of the disease, the occurrence of carcinoid syndrome with end stage hepatic disease can be postponed or prevented.

    The objective of this study was to evaluate the value of {sup 18}F-FDG PET/CT and S-100B tumour marker for the detection of liver metastases from uveal melanoma in comparison to liver metastases from cutaneous melanoma. A retrospective evaluation was conducted of 27 liver metastases in 13 patients with uveal melanoma (UM) (mean age: 56.8, range: 30-77) and 43 liver metastases in 14 patients (mean age: 57.9, range: 40-82) with cutaneous melanoma (CM) regarding size and FDG uptake by measuring the maximum standardized uptake value (SUV{sub max}). S-100B serum tumour markers were available in 20 patients. Cytology, histology, additional morphological imaging and follow-up served as reference standard. In nine patients liver metastases were further evaluated histologically regarding GLUT-1 and S-100 receptor expression and regarding epithelial or spindle cell growth pattern. Of 27 liver metastases in 6 of 13 patients (46%) with UM, 16 (59%) were FDG negative, whereas all liver metastases from CM were positive. Liver metastases from UM showed significantly (p < 0.001) lower SUV{sub max} (mean: 3.5, range: 1.5-13.4) compared with liver metastases from CM (mean: 6.6, range: 2.3-15.3). In four of six (66.7%) patients with UM and liver metastases S-100B was normal and in two (33.3%) increased. All PET-negative liver metastases were detectable by morphological imaging (CT or MRI). S-100B was abnormal in 13 of 14 patients with liver metastases from CM. S-100B values were significantly higher (p = 0.007) in the CM patient group (mean S-100B: 10.9 {mu}g/l, range: 0.1-115 {mu}g/l) compared with the UM patients (mean: 0.2 {mu}g/l, range: 0.0-0.5 {mu}g/l). Histological work-up of the liver metastases showed no obvious difference in GLUT-1 or S-100 expression between UM and CM liver metastases. The minority (36%) of patients with UM had extrahepatic metastases and the majority (86%) of patients with CM had extrahepatic metastases, respectively. There was a close to significant

    Full Text Available The discovery of various driver pathways and targeted small molecule agents/antibodies have revolutionized the management of metastatic breast cancer. Currently, the major targets of clinical utility in breast cancer include the human epidermal growth factor receptor 2 (HER2 and epidermal growth factor receptor (EGFR, vascular endothelial growth factor (VEGF receptor, mechanistic target of rapamycin (mTOR pathway, and the cyclin-dependent kinase 4/6 (CDK-4/6 pathway. Brain metastasis, however, remains a thorn in the flesh, leading to morbidity, neuro-cognitive decline, and interruptions in the management of systemic disease. Approximately 20%–30% of patients with metastatic breast cancer develop brain metastases. Surgery, whole brain radiation therapy, and stereotactic radiosurgery are the traditional treatment options for patients with brain metastases. The therapeutic paradigm is changing due to better understanding of the blood brain barrier and the advent of tyrosine kinase inhibitors and monoclonal antibodies. Several of these agents are in clinical practice and several others are in early stage clinical trials. In this article, we will review the common targetable pathways in the management of breast cancer patients with brain metastases, and the current state of the clinical development of drugs against these pathways.

    Purpose: We previously developed a multigene expression model of tumor radiation sensitivity index (RSI) with clinical validation in multiple independent cohorts (breast, rectal, esophageal, and head and neck patients). The purpose of this study was to assess differences between RSI scores in primary colon cancer and metastases. Methods and Materials: Patients were identified from our institutional review board–approved prospective observational protocol. A total of 704 metastatic and 1362 primary lesions were obtained from a de-identified metadata pool. RSI was calculated using the previously published rank-based algorithm. An independent cohort of 29 lung or liver colon metastases treated with 60 Gy in 5 fractions stereotactic body radiation therapy (SBRT) was used for validation. Results: The most common sites of metastases included liver (n=374; 53%), lung (n=116; 17%), and lymph nodes (n=40; 6%). Sixty percent of metastatic tumors, compared with 54% of primaries, were in the RSI radiation-resistant peak, suggesting metastatic tumors may be slightly more radiation resistant than primaries (P=.01). In contrast, when we analyzed metastases based on anatomical site, we uncovered large differences in RSI. The median RSIs for metastases in descending order of radiation resistance were ovary (0.48), abdomen (0.47), liver (0.43), brain (0.42), lung (0.32), and lymph nodes (0.31) (P<.0001). These findings were confirmed when the analysis was restricted to lesions from the same patient (n=139). In our independent cohort of treated lung and liver metastases, lung metastases had an improved local control rate compared to that in patients with liver metastases (2-year local control rate of 100% vs 73.0%, respectively; P=.026). Conclusions: Assessment of radiation sensitivity between primary and metastatic tissues of colon cancer histology revealed significant differences based on anatomical location of metastases. These initial results warrant validation in a larger

    Full Text Available MH Wong, N PavlakisDepartment of Medical Oncology, Royal North Shore Hospital, Sydney, NSW, AustraliaAbstract: Bone metastasis in breast cancer is a significant clinical problem. It not only indicates incurable disease with a guarded prognosis, but is also associated with skeletal-related morbidities including bone pain, pathological fractures, spinal cord compression, and hypercalcemia. In recent years, the mechanism of bone metastasis has been further elucidated. Bone metastasis involves a vicious cycle of close interaction between the tumor and the bone microenvironment. In patients with bone metastases, the goal of management is to prevent further skeletal-related events, manage complications, reduce bone pain, and improve quality of life. Bisphosphonates are a proven therapy for the above indications. Recently, a drug of a different class, the RANK ligand antibody, denosumab, has been shown to reduce skeletal-related events more than the bisphosphonate, zoledronic acid. Other strategies of clinical value may include surgery, radiotherapy, radiopharmaceuticals, and, of course, effective systemic therapy. In early breast cancer, bisphosphonates may have an antitumor effect and prevent both bone and non-bone metastases. Whilst two important Phase III trials with conflicting results have led to controversy in this topic, final results from these and other key Phase III trials must still be awaited before a firm conclusion can be drawn about the use of bisphosphonates in this setting. Advances in bone markers, predictive biomarkers, multi-imaging modalities, and the introduction of novel agents have ushered in a new era of proactive management for bone metastases in breast cancer.Keywords: breast cancer, bone metastases, bisphosphonates, denosumab, biomarkers, optimal management

    Full Text Available BACKGROUND: We aimed to evaluate the clinical significance of microvessel density (MVD, lymphatic vessel density (LVD, and cancer-associated fibroblasts (CAFs in relation to tumor location in advanced colorectal cancer (CRC. METHODS: Using immunohistochemistry, we examined 181 advanced CRC patients for CD31 and D2-40 to measure MVD and LVD, respectively, α-smooth muscle actin (SMA and desmin to identify CAFs, and PTEN to examine genetic changes of CAFs. To evaluate the regional heterogeneity of these properties, we examined tissue from four sites (the center and periphery of the primary cancer, a distant metastasis, and a lymph node metastasis in each patient. RESULTS: MVD, LVD, and CAFs showed significant heterogeneity with respect to the tumor location. LVD was the greatest in the center of the primary cancers and the amount of CAFs was the lowest in distant metastases. In distant metastases, those from the lung had higher LVD and MVD, but fewer CAFs than those from the liver, peritoneum, or ovary. Patients with low MVD and LVD in the center of the primary cancer had worse outcomes and patients with few CAFs in distant metastases and in the primary tumor had a lower survival rate. PTEN expression in CAFs in distant metastases was lost in 11 of 181 CRC patients (6.1%, which was associated with a worse prognosis. CONCLUSIONS: The microenvironment, including cancer-associated microvasculature and fibroblasts, is heterogeneous with respect to the tumor location in CRC patients. Therefore, heterogeneity of microenvironments should be taken into account when managing CRC patients.

    We previously identified claudin-2 as a functional mediator of breast cancer liver metastasis. We now confirm that claudin-2 levels are elevated in liver metastases, but not in skin metastases, compared to levels in their matched primary tumors in patients with breast cancer. Moreover, claudin-2 is specifically expressed in liver-metastatic breast cancer cells compared to populations derived from bone or lung metastases. The increased liver tropism exhibited by claudin-2-expressing breast cancer cells requires claudin-2-mediated interactions between breast cancer cells and primary hepatocytes. Furthermore, the reduction of the claudin-2 expression level, either in cancer cells or in primary hepatocytes, diminishes these heterotypic cell-cell interactions. Finally, we demonstrate that the first claudin-2 extracellular loop is essential for mediating tumor cell-hepatocyte interactions and the ability of breast cancer cells to form liver metastases in vivo. Thus, during breast cancer liver metastasis, claudin-2 shifts from acting within tight-junctional complexes to functioning as an adhesion molecule between breast cancer cells and hepatocytes.

    Full Text Available Background. The worldwide increasing incidence of thyroid cancer (TC is mainly due to a rise in its major form of differentiated TC (DTC: papillary. Most patients with DTC have a good prognosis; 10-year survival overall rates are as high as 85 %, but not greater than 40 % in a group of patients with distant metastases. At the same time, the lung is the most frequent target for distant metastases, accounting for 70 % of all sites.Objective: to estimate and compare the capabilities of different diagnostic techniques to detect lung metastases of DTC. Materials and methods. The results of diagnosing lung metastases were retrospectively analyzed in 36 patients (33 women and 3 men; mean age 53 years with DTC (29 patients with papillary TC and 7 with follicular TC treated at the department of radiotherapy with systemic therapy, Chelyabinsk Regional Clinical Oncology Center from 2011 to 2014.Results. Chest X-ray could reveal pulmonary metastases in 13 (36 % patients; lung pathology foci were absent in 23 (64 % patients. 131I whole-body scintigraphy (WBS proved to be of informative value in 24 (66.7 % patients, it displayed no increased accumulation of the radiopharmaceutical in the lung of 12 (33.3 % cases. Multislice spiral computed tomography (MSCT of the chest was carried out in 22 (61 % patients; out of them 21 (95.5 % were found to have 1.4-to-20-mm lung cancer foci. 18Fluorodeoxyglucose (18FDG positron emission tomography / computed tomography (PET / CT was performed in 18 (50 % patients, which showed 3–26-mm lung pathology foci in all the patents; out of them 16 (88.9 % were detected to have metastases owing to the CT component of this method. Thus, the highest sensitivity was exhibited by MSCT (95.5 %, 18FDG PET / CT (100 % due to its CT component, and 131I WBS (66.7 %.Conclusion. When lung metastases of DTC are suspected, 1 chest X-ray should be used as a screening test; 2 131I WBS should be performed in all patients; 3 MSCT of the chest is

    @@ The majority of men with advanced prostate cancer develop bone metastases as opposed to metastases at other sites.1 It has been unclear why prostate cancer selectively metastasizes to and proliferates in bone.Recently, Shiozawa et al.Delineated a mechanism that may account for the establishment of prostate cancer in bone.2 Specifically, they identified that prostate cancer cells compete with hematopoietic stem cells (HSC) for the osteoblast in the HSC niche of the bone.Defining the mechanisms through which prostate cancer cells establish themselves in bone is critical towards developing effective therapeutic strategies to prevent or target bone metastases.

    Liver is one of the most important organs in energy metabolism.Most plasma apolipoproteins and endogenous lipids and lipoproteins are synthesized in the liver.It depends on the integrity of liver cellular function,which ensures homeostasis of lipid and lipoprotein metabolism.When liver cancer occurs,these processes are impaired and the plasma lipid and lipoprotein patterns may be changed.Liver cancer is the fifth common malignant tumor worldwide,and is closely related to the infections of hepatitis B virus (HBV) and hepatitis C virus (HCV).HBV and HCV infections are quite common in China and other Southeast Asian countries.In addition,liver cancer is often followed by a procession of chronic hepatitis or cirrhosis,so that hepatic function is damaged obviously on these bases,which may significantly influence lipid and lipoprotein metabolism in vivo.In this review we summarize the clinical significance of lipid and lipoprotein metabolism under liver cancer.

    Changyin Wang

    Full Text Available Bone scintigraphies are widely applied for detecting bone metastases. The aim of this study was to investigate distribution features of bone metastases in pulmonary and prostate cancers. Bone scintigraphies were performed in 460 patients with pulmonary cancer and 144 patients with prostate cancer. Patients were divided into three groups according to the total number of bone metastases: few bone metastases, moderate bone metastases, and extensive bone metastases. We compared the distribution of bone metastases in the two cancers, and analyzed the relationship between the distribution of metastatic lesions and their metastatic patterns. A total of 2279 and 2000 lesions of bone metastases were detected in 258 patients with pulmonary cancer and 102 patients with prostate cancer, respectively. In patients with few bone metastases, the distributions of metastatic lesions in the vertebrae (χ2 = 16.0, P = 0.000 and thoracic bones (χ2 = 20.7, P = 0.002 were significantly different between pulmonary and prostate cancers. In cases with moderate bone metastases, the distributions in the vertebrae (χ2 = 6.6, P = 0.010, pelvis (χ2 = 15.1 P = 0.000, and thoracic bones (χ2 = 38.8, P = 0.000 were also significantly different between the two cancers. However, in patients with extensive bone metastases, the distributions were very similar. As the total number of bone metastases increased, their distribution in pulmonary cancer did not noticeably change, but the distribution in the vertebrae and thoracic bones of prostate cancer patients significantly changed. Accordingly, the distribution characteristics of bone metastases differed in pulmonary and prostate cancers, mainly in the early stages of metastasis.

    Full Text Available Abstract Backround Sigmoid colon cancer metachronous metastases commonly occur in the liver and lungs with sporadic reports also to the spleen, stomach, thyroid gland, abdominal wall and upper urinary tract. This is a rare case of metachronous metastases invading the mesorectum and the abdominal wall. Case presentation A 72-year-old female underwent sigmoidectomy for stage I (T2N0 M0 sigmoid colon cancer in May 2008. In June 2009, an abdominal computed tomography scan revealed a tumor 2 cm in size at the lower anterior mesorectum and a second mass 2 cm in size at the anterior abdominal wall midline. Total colonoscopy showed no mucosal lesion. The serum carcinoembryonic antigen level was normal. A biopsy of the mesorectum tumor showed similar histologic characteristics with the primary tumor. Since no other site of recurrence was identified, an abdominoperineal resection was attempted. During the operation and after the removal of the incision recurrence, sinus bradycardia and signs of myocardial ischemia were noticed. A loop transverse colostomy was immediately perfomed and the operation was terminated. Postoperative cardiologic examination revealed an acute myocardium infract. Chemo-radiation of the mesorectum tumor and re-evaluation for surgical excision was decided. Conclusion Metachronous metastasis of the mesorectum from sigmoid colon cancer is extremely rare. Although patterns of lymphatic spread from rectal cancer to sigmoid colon have recently been demonstrated, there is no evidence of metachronous mesorectum invasion from sigmoid colon cancer. This could be the issue for future trials.

    The prognosis of patients with colorectal liver metastases (CRLM) remains low despite advances in chemotherapy and surgery. The expression of h-prune (human homolog of Drosophila prune protein; HGNC13420), an exopolyphosphatase, is correlated with progression and aggressiveness in several cancers and promotes migration and invasion. We investigated the role of h-prune in CRLM. To investigate the role of h-prune, immunohistochemical analysis for h-prune was performed in 87 surgically resected specimens of CRLM obtained between 2001 and 2009 at the Hiroshima University Hospital. Immunohistochemical analysis revealed positive staining for h-prune in 24 (28%) cases. The overall survival rate was significantly lower in h-prune-positive cases than in h-prune-negative cases (p = 0.003). Multivariate analysis showed that h-prune positivity was the only independent factor related to poor overall survival of patients after curative hepatectomy of CRLM. In vitro and in vivo, h-prune-knocked-down and h-prune-overexpressing cells were analyzed. In vitro, h-prune was associated with increased cell motility and upregulation of epithelial-mesenchymal transition (EMT) markers. In a mouse model, h-prune was associated with invasion of the tumor and distant metastases. In summary, h-prune expression is a useful marker to identify high-risk patients for resectable colorectal liver metastasis. h-Prune expression is necessary for cancer cell motility and EMT and is associated with liver and lung metastasis in colorectal cancer cells. h-Prune could be a new prognostic marker and molecular target for CRLM.

    growth factor receptor 2 subtypes had similar median survival duration and mortality risk. Patients with triple-negative breast cancer had a median survival duration of only 9.9 months. CONCLUSION: Patients with spinal metastases with ER/HR (-) status and triple-negative breast cancer could be downgraded...... from score "5" to "3" in Tokuhashi scoring system and from "slow growth" to "moderate growth" in Tomita scoring system. Spine surgeons should be critical before performing high-risk extensive surgery in patients with ER/HR (-) status, and especially, in those with triple-negative status. LEVEL...... hazards regression model unadjusted and adjusted by age were used. RESULTS: Patients with ER-negative (-) breast cancer had 11 months shorter median survival duration (10.6 vs. 21.5 mo) and 48% higher mortality risk (P=0.03) than those with ER-positive (+) breast cancer. Patients with PgR (-) status had...

    Pre-therapeutic prediction of outcome is important for clinicians and patients in determining whether selective internal radiation therapy (SIRT) is indicated for hepatic metastases of colorectal cancer (CRC). Pre-therapeutic characteristics of 100 patients with colorectal liver metastases (CRLM) treated by radioembolization were analyzed to develop a nomogram for predicting survival. Prognostic factors were selected by univariate Cox regression analysis and subsequent tested by multivariate analysis for predicting patient survival. The nomogram was validated with reference to an external patient cohort (n = 25) from the Bonn University Department of Nuclear Medicine. Of the 13 parameters tested, four were independently associated with reduced patient survival in multivariate analysis. These parameters included no liver surgery before SIRT (HR:1.81, p = 0.014), CEA serum level ≥ 150 ng/ml (HR:2.08, p = 0.001), transaminase toxicity level ≥2.5 x upper limit of normal (HR:2.82, p = 0.001), and summed computed tomography (CT) size of the largest two liver lesions ≥10 cm (HR:2.31, p < 0.001). The area under the receiver-operating characteristic curve for our prediction model was 0.83 for the external patient cohort, indicating superior performance of our multivariate model compared to a model ignoring covariates. The nomogram developed in our study entailing four pre-therapeutic parameters gives good prediction of patient survival post SIRT. (orig.)

    2005-01-01

    To review the preventive approaches for recurrence after curative resection of hepatic metastases from coloreclal carcinoma, we have summarized all available publications reporting randomized control trials (RCTs) covered in PubMed. The treatment approaches presented above include adjuvant intrahepatic arterial infusion chemotherapy,systemic chemotherapy, neoadjuvant chemotherapy, and immunotherapy. Although no standard treatment has been established, several approaches present promising results, which are both effective and tolerable in posthepatectomy patients. Intrahepatic arterial infusion chemotherapy should be regarded as effective and tolerable and it increases overall survival (OS) and diseasefree survival (DFS) of patients, while 5-fluorouracil-based systemic chemotherapy has not shown any significant survival benefit. Fortunately chemotherapy combined with hepatic arterial infusion and intravenous infusion has shown OS and DFS benefit in many researches. Few neoadjuvant RCT studies have been conduced to evaluate its effect on prolonging survivals although many retrospective studies and case reports are published in which unresectable colorectal liver metastases are downstaged and made resectable with neoadjuvant chemotherapy.Liver resection supplemented with immunotherapy is associated with optimal results; however, it is also questioned by others. In conclusion, several adjuvant approaches have been studied for their efficacy on recurrence after hepatectomy for liver metastases from colorectal cancer (CRC), but multi-centric RCT is still needed for further evaluation on their efficacy and systemic or local toxicities. In addition, new adjuvant treatment should be investigated to provide more effective and tolerable methods for the patients with resectable hepatic metastases from CRC.

    A 48-year-old man was referred to our hospital with the diagnosis of colon cancer with multiple hepatic metastases. After right hemicolectomy, the rapid progression of liver disease was treated with metronomic capecitabine and bevacizumab according to a study protocol. A gradual regression of metastatic lesions was observed during a 9-month treatment period. After conversion of liver disease to resectability, the histological examination disclosed the complete necrosis of all lesions, with the exception of small neoplastic foci inside a single nodule. The comparison of this type of histological findings with the classic sclero-hyaline pathological response, as well as its importance as indicator of response to antiangiogenic treatment, is discussed.

    Full Text Available Patients with triple receptor-negative breast cancer often develop aggressive metastatic disease, which also might involve the brain. In many cases, systemic and local treatment is needed. It is important to consider the toxicity of chemo- and radiotherapy, especially when newly approved drugs become available. Randomised studies leading to drug approval often exclude patients with newly diagnosed brain metastases. Here we report our initial experience with eribulin mesylate and whole-brain radiotherapy (WBRT in a heavily pretreated patient with multiple brain, lung, and bone metastases from triple receptor-negative breast cancer. Eribulin mesylate was given after 4 previous lines for metastatic disease. Two weeks after the initial dose, that is, during the first cycle, the patient was diagnosed with 5 brain metastases with a maximum size of approximately 4.5 cm. She continued chemotherapy and received concomitant WBRT with 10 fractions of 3 Gy. After 3 cycles of eribulin mesylate, treatment was discontinued because of newly diagnosed liver metastases and progression in the lungs. No unexpected acute toxicity was observed. The only relevant adverse reactions were haematological events after the third cycle (haemoglobin 9.5 g/dL, leukocytes 3.1×109/L. The patient died from respiratory failure 18.5 months from diagnosis of metastatic disease, and 2.7 months from diagnosis of brain metastases. To the best of our knowledge, this is the first report on combined WBRT and eribulin mesylate.

    The paper discusses the capability for active movement in an extracellular matrix, wherein remodeling of the cytoskeleton by actin binding proteins plays a significant role in metastases formation. We studied the expression of actin binding proteins and β-catenin in tissues of primary tumors and metastases of ovarian and breast cancer. Contents of p45 Ser β-catenin and the actin severing protein gelsolin were decreased in metastases of ovarian cancer relative to primary tumors. The level of the cofilin, functionally similar to gelsolin, was significantly higher in metastases compared to primary ovarian and breast tumor tissue. In breast cancer, significant increase in the number of an actin monomer binder protein thymosin-β4 was observed in metastases as compared to primary tumors. The data obtained suggest the involvement of locomotor proteins in metastases formation in ovarian and breast cancer.

    Obesity has become a universal and major public health problem with increasing prevalence in both adults and children in the 21st century, even in developing countries. Extensive epidemiological studies reveal a strong link between obesity and development and progression of various types of cancers. The connection between obesity and liver cancer is particularly strong and obesity often results in liver diseases such as non-alcoholic fatty liver disease (NAFLD) and the more severe non-alcoholic steatohepatitis (NASH). NASH is characterized by fatty liver inflammation and is believed to cause fibrosis and cirrhosis. The latter is a known liver cancer risk factor. In fact due to its much higher prevalence obesity may be a more substantial contributor to overall hepatocellular carcinoma burden than infection with hepatitis viruses. Here we review and discuss recent advances in elucidation of cellular and molecular alterations and signaling pathways associated with obesity and liver inflammation and their contribution to hepatocarcinogenesis.

    Presentation of techniques and procedures for regional chemotherapy in the treatment of unresectable liver metastases from different primary tumors as a modality of interdisciplinary therapy management. Such transarterial therapy methods include hepatic arterial infusion (HAI), transarterial chemoembolization (TACE), chemoembolization with cytostatic-loaded microspheres (DEBs), transarterial embolization (TAE) and selective internal radiation therapy (SIRT). Regional chemotherapy procedures in the treatment of liver metastases represent a minimally invasive treatment option that can be successfully combined with surgical resection and/or radiofrequency (RFA), laser-induced thermotherapy (LITT), microwave ablation (MWA). These procedures allow optimization of the local control rate with strictly intrahepatic processes and lead to increased survival rates without any quality of life restriction. (orig.)

    2016-10-01

    Full Text Available Colorectal cancer (CRC is one of the most common cancers in the developed countries, and nearly 70% of patients with CRC develop colorectal liver metastases (CRLMs. During the last decades, several scores have been proposed to predict recurrence after CRLM resection. However, these risk scoring systems do not accurately reflect the prognosis of these patients. Therefore, this investigation was designed to identify a proteomic profile in human hepatic tumor samples to classify patients with CRLM as “mild” or “severe” based on the 5-year survival. The study was performed on 85 CRLM tumor samples. Firstly, to evaluate any distinct tumor proteomic signatures between mild and severe CRLM patients, a training group of 57 CRLM tumor samples was characterized by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry, and a classification and regression tree (CART analysis was subsequently performed. Finally, 28 CRLM tumor samples were used to confirm and validate the results obtained. Based on all the protein peaks detected in the training group, the CART analysis was generated, and four peaks were considered to be the most relevant to construct a diagnostic algorithm. Indeed, the multivariate model yielded a sensitivity of 85.7% and a specificity of 86.1%, respectively. In addition, the receiver operating characteristic (ROC curve showed an excellent diagnostic accuracy to discriminate mild from severe CRLM patients (area under the ROC: 0.903. Finally, the validation process yielded a sensitivity and specificity of 68.8% and 83.3%, respectively. We identified a proteomic profile potentially useful to determine the prognosis of CRLM patients based on the 5-year survival.

    Full Text Available One in four breast cancer patients is at risk of developing bone metastases in her life time. The early prevention of bone metastases is a crucial challenge. It has been suggested that the use of zoledronic acid (ZOL in the adjuvant setting may reduce the persistence of disseminated tumor cells and thereby might improve outcome, specifically in a population of patients with a low estrogen microenvironment. More recently, the results of a large meta-analysis from 41 randomized trials comparing a bisphosphonate (BP to placebo or to an open control have been presented at the 2013 San Antonio Breast Cancer Meeting. Data on 17,016 patients confirm that adjuvant BPs, irrespective of the type of treatment or the treatment schedule and formulation (oral or intra-venously (IV, significantly reduced bone recurrences and improved breast cancer survival in postmenopausal women. No advantage was seen in premenopausal women. BPs are soon likely to become integrated into standard practice. Published data on the mechanisms involved in tumor cell seeding from the primary site, in homing to bone tissues and in the reactivation of dormant tumor cells will be reviewed; these might offer new ideas for innovative combination strategies.

    Biochemically failing metastatic prostate cancer is typically treated with androgen ablation. However, due to the emergence of castration-resistant cells that can survive in low androgen concentrations, such therapy eventually fails. Here, we develop a partial differential equation model of the growth and response to treatment of prostate cancer that has metastasized to the bone. Existence and uniqueness results are derived for the resulting free boundary problem. In particular, existence and uniqueness of solutions for all time are proven for the radially symmetric case. Finally, numerical simulations of a tumor growing in 2-dimensions with radial symmetry are carried in order to evaluate the therapeutic potential of different treatment strategies. These simulations are able to reproduce a variety of clinically observed responses to treatment, and suggest treatment strategies that may result in tumor remission, underscoring our model's potential to make a significant contribution in the field of prostate cancer therapeutics.

    In the last module of this consensus, controversial topics were discussed. Management of the disease after progression during first line chemotherapy was the first discussion. Next, the benefits of liver resection in the presence of extra-hepatic disease were debated, as soon as, the best sequence of treatment. Conversion chemotherapy in the presence of unresectable liver disease was also discussed in this module. Lastly, the approach to the unresectable disease was also discussed, focusing in the best chemotherapy regimens and hole of chemo-embolization. RESUMO Neste último módulo do consenso, abordou-se alguns temas controversos. O primeiro tópico discutido foi o manejo da doença após progressão na primeira linha de quimioterapia, com foco em se ainda haveria indicação cirúrgica neste cenário. A seguir, o painel debruçou-se sobre as situações de ressecção da doença hepática na presença de doença extra-hepática, assim como, qual a melhor sequência de tratamento. O tratamento de conversão para doença inicialmente irressecável também foi abordado neste módulo, incluindo as importantes definições de quando se pode esperar que a doença se torne ressecável e quais esquemas terapêuticos seriam mais efetivos à luz dos conhecimentos atuais sobre a biologia tumoral e taxas de resposta objetiva. Por último, o tratamento da doença não passível de ressecção foi discutida, focando-se nos melhores esquemas a serem empregados e seu sequenciamento, bem como o papel da quimioembolização no manejo destes pacientes.

    Full Text Available We report a case of ovarian carcinoid tumor that recurred with multiple liver metastases and was successfully treated with chemoembolization. A 76-year-old woman was admitted to our hospital presented with abdominal distension and abnormal uterine bleeding for about 6 months. She presented with hyperestrogenic and androgenic manifestations such as vaginal bleeding with endometrial hyperplasia and hirsutism. Magnetic resonance (MR imaging revealed a large solid and cystic ovarian tumor of 17 cm at maximum diameter. On the basis of the clinical diagnosis of sex cord stromal tumor containing a mature cystic teratoma, she underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. The pathology report revealed that the mass in the left ovary was a carcinoid tumor, insular type, with mature cystic teratoma. Two years after surgical treatment, multiple liver metastases were revealed by abdominal CT. Hepatic arterial infusion of cisplatin was performed for 2 courses, and multiple metastatic nodules have remarkably reduced. No established chemotherapy or radiation therapy treatments are currently available for recurrent or advanced carcinoid tumors. Our paper suggests that chemoembolization with cisplatin may be effective in treatment of patients with multiple liver metastases of ovarian carcinoid tumor.

    Liver cancer (hepatocellular carcinoma or HCC) is a major cancer worldwide. Research in this field is needed to identify biomarkers that can be used for early detection of the disease as well as new approaches to its treatment. Epigenetic biomarkers provide an opportunity to understand liver cancer etiology and evaluate novel epigenetic inhibitors for treatment. Traditionally, liver cirrhosis, proteomic biomarkers, and the presence of hepatitis viruses have been used for the detection and diagnosis of liver cancer. Promising results from microRNA (miRNA) profiling and hypermethylation of selected genes have raised hopes of identifying new biomarkers. Some of these epigenetic biomarkers may be useful in risk assessment and for screening populations to identify who is likely to develop cancer. Challenges and opportunities in the field are discussed in this chapter.

  8. Phase II study of neoadjuvant 5-FU + leucovorin + CPT-11 in patients with resectable liver metastases from colorectal adenocarcinoma

    Full Text Available Abstract Background Following resection of liver metastases from colorectal cancer, 5-year survivals are reportedly 30 – 39%. It can be assumed that this clinical situation represents systemic disease. Therefore, it is postulated that systemic chemotherapy would improve outcomes, particularly in those whose disease is sensitive to the agents administered. One potential advantage of neoadjuvant chemotherapy is that it provides in vivo chemosensitivity data. Response to neoadjuvant chemotherapy could therefore guide adjuvant chemotherapy following resection of liver metastases from colorectal cancer. Methods and design This is a prospective Phase II evaluation of outcomes in patients with potentially resectable liver metastases. Patients will receive neoadjuvant chemotherapy and will undergo resection. Postoperative chemotherapy will be directed by the degree of response to preoperative chemotherapy. All patients with Stage IV colorectal adenocarcinoma isolated to the liver that have disease that is amenable to complete ablation by resection, radiofrequency ablation, and/or cryoablation will be candidates for the trial. Patients will receive CPT-11 180 mg/m2 IV (over 90 minutes on day 1 with 5-FU 400 mg/m2 bolus and 600 mg/m2 by 22 hour infusion and calcium folinate 200 mg/m2 on days 1 and 2, every 2 weeks. Altogether, six cycles of chemotherapy will be administered. Patients will then undergo resection and/or radiofrequency ablation. Patients who had stable disease or a clinical response with preoperative chemotherapy will receive an additional 12 cycles of CPT-11 180 mg/m2 IV (over 90 minutes on day 1 with 5-FU 400 mg/m2 bolus and 600 mg/m2 by 22 hour infusion and calcium folinate 200 mg/m2 on days 1 and 2 (given every 2 weeks. Patients with resectable disease who had progressive disease during neoadjuvant chemotherapy will receive best supportive care or an alternative agent, at the discretion of the treating physician. Those patients who are

    Purpose. To present thermal ablation of liver metastases via laser induced thermotherapy. Material and methods. Different technical procedures of thermal ablation and online monitoring are used, as there are the MR-guided laser induced thermotherapy (LITT) and the radiofrequency ablation thermotherapy (RF). Results. In a prospective non randomized study 606 patients with liver metastases were treated via MR-guided laserinduced thermotherapy. Inclusion criteria were the exclusion of extrahepatic tumor spread and a number of metastases lower than 5 and a size lower than 50 mm in diameter. The local tumor control rate in the 3 month and 6 month control study was 98,3%, the complication rate 3,5% (clinically relevant: 1,2%). The mean survival rate was 40,9 months for all patients with liver metastases without statistically relevant differences for various primaries, like colorectal carcinoma, breast cancer and various other tumors. Results for radiofrequency are so far limited with incidence of a higher local tumor recurrence rate versus LITT. Conclusion. MR-guided LITT results in a high local tumor control rate with improved survival. (orig.) [German] Zielsetzung.

    Purpose: We evaluated the diagnostic accuracy of magnetic resonance imaging (MRI) and positron emission tomography (PET) for detection of liver metastases in malignant melanoma. Material and methods: Thirty-five patients with 39 combined unenhanced MRI and fluorine-18 deoxyglucose (F-18 FDG) PET scans were prospectively studied. In discordant imaging findings final diagnosis was proven by clinical follow-up >6 months and demonstration of progressive liver metastases by at least one imaging method. Sensitivities and specificities were compared and the influence of lesion size and melanin content on diagnostic accuracy was determined. Results: MRI and PET were concordantly negative for presence and number of liver metastases in 28 patients and positive in four patients. PET and MRI were false positive in one patient each. In one patient MRI showed a single metastases not seen by PET and in one patient MRI demonstrated more metastases at the first examination. In follow-up investigations MRI revealed more metastases than PET in both patients. The sensitivities for lesion detection were 47% (16/34) for PET and 100% for MRI. Lesion detectability by PET was related to lesion size (P < 0.0001) but not to melanin content. Conclusion: MRI is more sensitive in the detection of liver metastases in patients with malignant melanoma. Small lesions are easily missed by PET, while melanin content does not influence detectability by PET.

  11. Characterization and propagation of tumor initiating cells derived from colorectal liver metastases: trials, tribulations and a cautionary note.

    Directory of Open Access Journals (Sweden)

    Mark I James

    Full Text Available Tumor initiating cells (TIC are increasingly being put forward as a potential target for intervention within colorectal cancer. Whilst characterisation and outgrowth of these cells has been extensively undertaken in primary colorectal cancers, few data are available describing characteristics within the metastatic setting. Tissue was obtained from patients undergoing surgical resection for colorectal liver metastases, and processed into single cell suspension for assessment. Tumor initiating cells from liver metastases were characterised using combinations of EPCAM, Aldehyde dehydrogenase activity, CD133 and CD26. CD133 expression was significantly lower in patients who had received chemotherapy, but this was accounted for by a decrease observed in the male patient cohort only. ALDHhigh populations were rare (0.4 and 0.3% for EPCAM+/ALDHhigh/CD133- and EPCAM+/ALDHhigh/CD133+ populations respectively and below the limits of detection in 28% of samples. Spheroid outgrowth of metastatic tumor cells across all samples could not be readily achieved using standard spheroid-formation techniques, thus requiring further method validation to reliably propagate cells from the majority of tissues. Spheroid formation was not enhanced using additional growth factors or fibroblast co-culture, but once cells were passaged through NOD-SCID mice, spheroid formation was observed in 82% samples, accompanied by a significant increase in CD26. Order of spheroid forming ability was ALDHhigh>CD133>CD26. Samples sorted by these markers each had the ability to reform ALDHhigh, CD133 and CD26 positive populations to a similar extent, suggestive of a high degree of plasticity for each population. Ex vivo TIC models are increasingly being utilised to assess efficacy of therapeutic interventions. It is therefore essential that such investigations use well-characterised models that are able to sustain TIC populations across a large patient cohort in order that the inherent

Computed tomography scan showed a hypervascular solid lesion arising in the pancreatic body and invading the celiac axis and portal vein with liver metastases. Ultrasound-guided liver biopsy diagnosed a serous cystic neoplasm, indistinguishable from serous cystadenoma. Based on clinical, radiological and pathological correlation, the diagnosis of cystadenocarcinoma was established. There are few reported cases of malignant serous cystic neoplasms in which malignancy was confirmed. Although rare in males, cystadenocarcinoma should be considered in the differential diagnosis of patients presenting with a pancreatic mass and liver metastasis.

    The causality between the metastatic potential, mismatch repair status (MMR) and survival in colorectal cancer (CRC) is complex. This study aimed to investigate the impact of MMR in CRC on the occurrence of synchronous metastases (SCCM) and survival in patients with SCCM on a national basis....... A nationwide cohort study of 6,692 patients diagnosed with CRC between 2010 and 2012 was conducted. Data were prospectively entered into the Danish Colorectal Cancer Group's database and merged with data from the Danish Pathology Registry and the National Patient Registry. Multivariable and multinomial...... metastases (aOR = 0.69, 95% CI:0.26-1.29, p = 0.436) were unaffected by MMR. MMR in patients with SCCM had no impact on survival (Cox: adjusted Hazard Ratio (aHR) = 0.76, 95% CI: 0.54-1.06, p = 0.101; Proportional excess hazards: aHR = 0.73, 95% CI: 0.50-1.07, p = 0.111) when adjusting for other prognostic...

    Full Text Available Abstract Background Besides being the effectors of native anti-tumor cytotoxicity, NK cells participate in T-lymphocyte responses by promoting the maturation of dendritic cells (DC. Adherent NK (A-NK cells constitute a subset of IL-2-stimulated NK cells which show increased expression of integrins and the ability to adhere to solid surface and to migrate, infiltrate, and destroy cancer. A critical issue in therapy of metastatic disease is the optimization of NK cell migration to tumor tissues and their persistence therein. This study compares localization to liver metastases of autologous A-NK cells administered via the systemic (intravenous, i.v. versus locoregional (intraarterial, i.a. routes. Patients and methods A-NK cells expanded ex-vivo with IL-2 and labeled with 111In-oxine were injected i.a. in the liver of three colon carcinoma patients. After 30 days, each patient had a new preparation of 111In-A-NK cells injected i.v. Migration of these cells to various organs was evaluated by SPET and their differential localization to normal and neoplastic liver was demonstrated after i.v. injection of 99mTc-phytate. Results A-NK cells expressed a donor-dependent CD56+CD16+CD3- (NK or CD56+CD16+CD3+ (NKT phenotype. When injected i.v., these cells localized to the lung before being visible in the spleen and liver. By contrast, localization of i.a. injected A-NK cells was virtually confined to the spleen and liver. Binding of A-NK cells to liver neoplastic tissues was observed only after i.a. injections. Conclusion This unique study design demonstrates that A-NK cells adoptively transferred to the liver via the intraarterial route have preferential access and substantial accumulation to the tumor site.

    The prognosis for patients with liver metastases depends on the therapeutic options regarding the treatment of the primary tumor, co-existing extrahepatic metastases and the extent and treatment possibilities of the hepatic metastases themselves. Numerous curative or palliative oncological therapeutic concepts have been introduced in case of non-resectable liver metastases to prolong survival while maintaining a highest possible quality of life. Cryotherapy, which can be performed percutaneously and under magnetic resonance guidance, is one of these manifold therapeutic modalities, combining the inherent advantages of MRI with minimal invasiveness. Excellent visualization of the frozen liver tissue, precise tumor ablation, as well as an almost painless intervention due to the analgetic effect of the ice are implicating percutaneous cryotherapy as an attractive alternative to other ablation techniques. First clinical results are promising. However, meticulous and extensive long-term evaluation on a broad clinical scale is required. (orig.) [German] Die Prognose eines Patienten mit hepatischen Filiae haengt von den Behandlungsmoeglichkeiten des Primaertumors, vom Vorhandensein weiterer Metastasen und von der Ausdehnung und den Behandlungsmoeglichkeiten der Lebermetastasen selbst ab. Bei chirurigsch nicht resektablen Lebermetastasen kommen zahlreiche kurative oder palliative onkologische Therapiekonzepte in Frage, saemtlich mit dem Ziel einer moeglichst hohen Ueberlebensrate und Lebensqualitaet. Eine dieser Therapiestrategien ist die Kryotherapie, die perkutan unter kernspintomographischer Kontrolle durchgefuehrt werden kann und somit die inhaerenten Vorteile der MRT mit einem wenig invasiven Verfahren verbindet. Eine exzellente Darstellbarkeit gefrorenen Lebergewebes, eine praezise Tumorablation sowie ein nahezu schmerzfreier Eingriff aufgrund des analgetischen Effektes tiefer Temperaturen machen die perkutane Kryotherapie zu einer attraktiven Alternative zu anderen

    OBJECTIVE To evaluate the safety and effectiveness of treatment of hepatic metastases from colorectal cancer using high-intensity focused ultrasound (HIFU). METHODS Thirty-one lesions in 18 patients with hepatic metastases from colorectal cancer after colectomy were treated with HIFU therapy. The vital signs, function of the vital organs, complications and pathological outcome were studied using imaging examinations such as CT or MRI. RESULTS The vital signs of all patients remained stable and their liver and kidney functions normal. Two of the 18 patients were not followed-up. After a mean follow-up of 16.1 months (6-38 months), 13 survived. The survival rates at the 12th and 18th months were 83.3% and 66.7%, respectively. The median survival rate was 16 months. Among the 25 lesions followed-up, 17 shrank over 50%, 5 grew new metastases and superficial degree II skin injury occurred in 8. CONCLUSION HIFU is a safe, effective and non-invasive option for the treatment of hepatic metastases from colorectal cancer.

  19. Downregulation of CXCR4 in Metastasized Breast Cancer Cells and Implication in Their Dormancy.

    Directory of Open Access Journals (Sweden)

    Kentaro Nobutani

    Full Text Available Our understanding of the mechanism of cancer dormancy is emerging, but the underlying mechanisms are not fully understood. Here we analyzed mouse xenograft tumors derived from human breast cancer tissue and the human breast cancer cell line MDA-MB-231 to identify the molecules associated with cancer dormancy. In immunohistological examination using the proliferation marker Ki-67, the tumors included both proliferating and dormant cancer cells, but the number of dormant cells was remarkably increased when they metastasized to the lung. In the gene expression analysis of the orthotopic cancer cells by a single-cell multiplex real-time quantitative reverse transcription PCR followed by flow cytometric analysis, restrained cellular proliferation was associated with downregulation of the chemokine receptor CXCR4. In the immunohistological and flow cytometric analyses, the expression level of CXCR4 in the metastasized cancer cells was decreased compared with that in the cancer cells in orthotopic tumors, although the expression level of the CXCR4 ligand CXCL12 was not reduced in the lung. In addition, the proliferation of the metastasized cancer cells was further decreased by the CXCR4 antagonist administration. In the ex vivo culture of the metastasized cancer cells, the expression level of CXCR4 was increased, and in the xenotransplantation of ex vivo cultured cancer cells, the expression level of CXCR4 was again decreased in the metastasized cancer cells in the lung. These findings indicate that CXCR4 is downregulated in metastasized breast cancer cells and implicated in their dormancy.

    The application of gene transfer technologies to the treatment of cancer has led to the development of new experimental approaches like gene directed enzyme/prodrug therapy (GDEPT), inhibition of oncogenes and restoration of tumor-suppressor genes. In addition,gene therapy has a big impact on other fields like cancer immunotherapy, anti-angiogenic therapy and virotherapy.These strategies are being evaluated for the treatment of primary and metastatic liver cancer and some of them have reached clinical phases. We present a review on the basis and the actual status of gene therapy approaches applied to liver cancer.

    Full Text Available Hepatic porphyries have been associated with an increased risk of primary liver cancer (PLC, which on the other hand may cause an increased porphyrin production. To evaluate the role of an underlying liver disorder we analyzed porphyrins in patients with hepatocellular carcinoma (HCC (n=65, cholangiocellular carcinoma (n=3, or suspected PLC, which turned out to be metastases (n=18 or a benign disorder (n=11. None of the patients had a family history of porphyry or clinical signs of porphyry. Increased aminolevulinic acid or porphyrin values were common not only in patients with PLC (43% but also in metastatic (50% and benign (64% liver disorders. The corresponding proportion for HCC patients with liver cirrhosis (55% was higher (P<.05 than in those without cirrhosis (17%. We conclude that symptomatic porphyries are unusual in PLC, whereas elevated urinary and/or faecal porphyrins are common, primarily reflecting a parallel liver disease and not the PLC.

    Therapeutic options for treating unresectable hepatic metastases of leiomyosarcomas were scarce until a few years ago. Recent advances in the study of the biology of intestinal tumours have radically changed our knowledge of their pathogenesis. Many of the tumours previously considered as leiomyosarcomas are now identified as gastrointestinal stromal tumours (GISTs). The introduction of imatinib (an antineoplasic drug that specifically acts on the pathogenesis of these tumours) has shown promising results in patients with advanced GISTs. We present three patients with the initial diagnosis of unresectable hepatic metastases of leiomyosarcomas. They received liver transplants. All three had tumour recurrences after transplantation. Histological re-evaluation identified a stromal origin of the tumours, and the patients were treated with imatinib therapy (400 mg/day). Recurrence occurred in all patients after a mean of 38.3 months, but imatinib treatment achieved control of the tumours. The current survival times with the combination of transplantation and imatinib are 92, 48 and 46 months for the three patients. This series is small and inconclusive, but imatinib treatment showed promising results. The treatment options for patients with unresectable metastases of GISTs must be defined, as in these three patients liver transplantation achieved a disease-free status but all had tumour recurrences before starting the imatinib treatment.

    Full Text Available Evidence about distribution patterns of brain metastases with regard to breast cancer subtypes and its influence on the prognosis of patients is insufficient. Clinical data, cranial computed tomography (CT and magnetic resonance imaging (MRI scans of 300 breast cancer patients with brain metastases (BMs were collected retrospectively in four centers participating in the Brain Metastases in Breast Cancer Registry (BMBC in Germany. Patients with positive estrogen (ER, progesterone (PR, or human epidermal growth factor receptor 2 (HER2 statuses, had a significantly lower number of BMs at diagnosis. Concerning the treatment mode, HER2-positive patients treated with trastuzumab before the diagnosis of BMs showed a lower number of intracranial metastases (p < 0.001. Patients with a HER2-positive tumor-subtype developed cerebellar metastases more often compared with HER2-negative patients (59.8% vs. 44.5%, p = 0.021, whereas patients with triple-negative primary tumors had leptomeningeal disease more often (31.4% vs. 18.3%, p = 0.038. The localization of Brain metastases (BMs was associated with prognosis: patients with leptomeningeal disease had shorter survival compared with patients without signs of leptomeningeal disease (median survival 3 vs. 5 months, p = 0.025. A shorter survival could also be observed in the patients with metastases in the occipital lobe (median survival 3 vs. 5 months, p = 0.012. Our findings suggest a different tumor cell homing to different brain regions depending on subtype and treatment.

    Full Text Available Hürthle cell thyroid cancer (HCTC is a less common form of differentiated thyroid cancer. It rarely metastasizes to the liver, and when it does, the metastasis is almost never isolated. Here we report a 62-year-old male with widely invasive Hürthle cell thyroid cancer, who underwent total thyroidectomy and received adjuvant treatment with I-131 with posttreatment scan showing no evidence of metastatic disease. His thyroglobulin however continued to rise after that and eventually an isolated liver metastasis was identified. He underwent laparoscopic microwave ablation of the liver metastasis, with dramatic decline in thyroglobulin and no structural disease identified to date. This case highlights the rare occurrence of isolated liver metastasis from HCTC and also illustrates the utility of thermoablation as an alternative to surgical resection in the treatment of small isolated liver metastases from HCTC.

    Full Text Available The aim of this study was to compare the diagnostic accuracy of [18F]FDG-PET/MRI with PET/CT for the detection of liver metastases.32 patients with solid malignancies underwent [18F]FDG-PET/CT and subsequent PET/MRI of the liver. Two readers assessed both datasets regarding lesion characterization (benign, indeterminate, malignant, conspicuity and diagnostic confidence. An imaging follow-up (mean interval: 185±92 days and/-or histopathological specimen served as standards of reference. Sensitivity, specificity, positive predictive value (PPV and negative predictive value (NPV were calculated for both modalities. Accuracy was determined by calculating the area under the receiver operating characteristic (ROC curve. Values of conspicuity and diagnostic confidence were compared using Wilcoxon-signed-rank test.The standard of reference revealed 113 liver lesions in 26 patients (malignant: n = 45; benign: n = 68. For PET/MRI a higher accuracy (PET/CT: 82.4%; PET/MRI: 96.1%; p<0.001 as well as sensitivity (67.8% vs. 92.2%, p<0.01 and NPV (82.0% vs. 95.1%, p<0.05 were observed.

    Full Text Available Following failure of systemic chemotherapy, transarterial chemoembolization (TACE is an available method to control unresectable liver metastases from colorectal carcinoma (CRC. The aim of present study was to evaluate the efficacy of chemoembolization for inoperable metastatic liver lesions from CRC. Forty-five CRC patients with liver metastases resistant to systemic chemotherapy were enrolled in our study. For each patient, three session of TACE were conducted with 45 days interval. A combination of mitomycin, doxorubicin, and lipiodol were used for TACE. A tri-phasic computed tomography scan and biochemical laboratory tests were performed for all patients at baseline and 30 days after each TACE. Image analysis included measurement of lesion diameters as well as contrast enhancement. Eleven patients deceased before completing three session and the final analyses were performed on the remaining 34 patients. Evaluation of a total 93 lesions in all patients after chemoembolization sessions revealed a 25.88% reduction in anteroposterior (AP diameter, 33.92% transverse (T diameter, and 42.22% in product of APxT diameter of lesions (P<0.001 for all instances. CT scan showed a total disappearance of 33% of lesions and evident reduction in contrast enhancement in 16% of them. There were no changes in contrast enhancement in 51% of lesions. Evaluation of single largest lesion in each patient revealed 57.32% reduction in AP diameter, 59.66% in T diameter, and 62.17% in product of APxT diameters (P<0.001 for all diameters. TACE offers a viable option for CRC patients with unresectable liver metastases by significantly reducing lesion size and contrast enhancement.

  8. Malnutrition, liver damage, and cancer.

    There is no clear indication that malnutrition, per se, is a principal cause of cancer in man, but the prevalence of liver cancer in areas where malnutrition exists supports this hypothesis. Liver damage and liver cancer have been induced in laboratory rats by diets consisting of peanut meal and proteins deficient in some essential amino acids. However, liver damage, but not cancer, was produced when the diets contained no peanut meal but consisted of a mixture of amino acids deficient in methionine and cysteine, so that it is possible that aflatoxin, a contaminant of peanut meal, may have been responsible for the malignancies seen in the earlier experiments. Liver cancer developes in a high proportion of mice allowed to feed ad libitum or given a diet containing a high proportion of fat (groundnut oil) or protein (casein). Dietary restriction reduced the incidences of this cancer. This findings lends some support to current thinking that diet may be a factor in the development of cancer in man.

    Full Text Available Context :Insulinomas may be regarded as potentially malignant. A long follow-up period is needed to detect any possible recurrence, even if the initial diagnosis was of a benign insulinoma. Case report :We present the case of a 76- year-old woman with liver metastases due to a malignant insulinoma, which had been diagnosed as benign after its complete removal 9 years earlier. Conclusions :This case shows the difficulty of distinguishing between benign and malignant insulinomas when there is no initial evidence of metastases. This fact poses the need to conduct a long follow-up period in order to detect any possible recurrence even if the initial diagnosis was one of a benign insulinoma.

    Between October 1983 and January 1986, sexteen patients with inoperable liver metastases from colorectal carcinomas were treated by single or cyclical intraarterial chemotherapy introduced either through an angiographic catheter or by means of a subcutaneously implanted access point (Port-A-Cath). Before each treatment cycle, the position of the catheter and the state of the vessels was examined by subtraction angiography in order to avoid complications and to confirm that the cytostatic agents were actually perfusing metastases, as shown by angio-CT. The complementary nature of the information obtained by these methods and their superiority over scintigraphy with /sup 99m/Tc macroaggregated albumin particles is documented and the most frequent complications of regional tumour therapy are described.

    Background APOBEC3B was recently identified as a gain-of-function enzymatic source of mutagenesis, which may offer novel therapeutic options with molecules that specifically target this enzyme. In primary breast cancer, APOBEC3B mRNA is deregulated in a substantial proportion of cases and its expression is associated with poor prognosis. However, its expression in breast cancer metastases, which are the main causes of breast cancer-related death, remained to be elucidated. Patients and methods RNA was isolated from 55 primary breast cancers and paired metastases, including regional lymph node (N = 20) and distant metastases (N = 35). APOBEC3B mRNA levels were measured by RT-qPCR. Expression levels of the primary tumors and corresponding metastases were compared, including subgroup analysis by estrogen receptor (ER/ESR1) status. Results Overall, APOBEC3B mRNA levels of distant metastases were significantly higher as compared to the corresponding primary breast tumor (P = 0.0015), an effect that was not seen for loco-regional lymph node metastases (P = 0.23). Subgroup analysis by ER-status showed that increased APOBEC3B levels in distant metastases were restricted to metastases arising from ER-positive primary breast cancers (P = 0.002). However, regarding ER-negative primary tumors, only loco-regional lymph node metastases showed increased APOBEC3B expression when compared to the corresponding primary tumor (P = 0.028). Conclusion APOBEC3B mRNA levels are significantly higher in breast cancer metastases as compared to the corresponding ER-positive primary tumors. This suggests a potential role for APOBEC3B in luminal breast cancer progression, and consequently, a promising role for anti-APOBEC3B therapies in advanced stages of this frequent form of breast cancer.

    We wanted to assess the safety and efficacy of performing radiofrequency ablation (RFA) in patients with non-colorectal liver metastases. In this retrospective study, 25 patients with 40 hepatic metastases (M:F = 17:8; mean age, 57 years; tumor size, 0.5-5.0 cm) from a non-colorectal origin (stomach, biliary, breast, pancreas, kidney and skin) were treated with RFA. The RFA procedures were performed using either an internally cooled electrode or a clustered electrode under ultrasound or CT guidance. Contrast-enhanced CT scans were obtained immediately after RFA and follow-up CT scans were performed within three months after ablation and subsequently at least every six months. The intrahepatic disease-free interval was estimated and the overall survival from the time of the initial RFA was analyzed using the Kaplan-Meier method. No intraprocedural deaths occurred, but four major complications developed, including abscesses (n = 3) and pneumothorax (n 1). Technical effectiveness was determined on the initial follow-up images. During the follow-up period (range, 5.9-68.6 months; median time, 18.8 months) for 37 tumors in 22 patients where technical effectiveness was achieved, 12 lesions (32%, 12 of 37) showed local tumor progression and new intrahepatic metastases occurred in 13 patients (59%, 13 of 22). The median intrahepatic disease-free interval was 10.1 months. The 1-year, 3-year and 5-year overall survival rates after RFA were 86%, 39% and 19%, respectively RFA showed intermediate therapeutic effectiveness for the treatment of non-colorectal origin liver metastases.

    Background The incidence of brain metastases in patients with breast cancer is approximately 10%-16%,and survival after diagnosis of brain metastases is usually short.This study was designed to evaluate the risk factors associated with brain metastases in advanced breast cancer patients,with a view to help predict patient groups with high risk of brain metastases.Methods In total,295 patients with advanced breast cancer were evaluated.All patients were pathologically confirmed and metastatic lesions were confirmed pathologically or by imaging.All patients were examined at least once every 6 months with head CT or MRI.Patients showing symptoms underwent immediate inspection,and brain metastatic lesions were confirmed by head CT and/or MRI.Results At a median follow-up of 12 months from the occurrence of metastases,brain metastases had occurred in 49 patients (16.6%).In our univariate analysis,variables significantly related to increased risk of brain metastases were hormone receptor-negative tumors,epidermal growth factor receptor 2 (HER2)-positive tumors,and multiple distant metastases.Patients with dominant tumor sites in soft tissue,or defined as Luminal A subtype,tended to have a lower risk of brain metastases than patients with visceral metastases,Luminal B subtype,triple-negative subtype or HER2-enriched subtype tumors.Conclusions Our results strongly suggest that factors such as Luminal B,triple-negative,and HER2-enriched subtypes are high risk factors for brain metastases.These data,therefore,provide pivotal clinical evidence towards a comprehensive understanding of the risk factors of brain metastases in advanced breast cancer patients.

    To compare diffusion-weighted (DW) and T2-weighted MR imaging in detecting colorectal liver metastases in a rat model, using histological examination as a reference method. Eighteen rats had four liver injections of colon cancer cells. MR examinations at 7 T included FSE-T2-weighted imaging and SE-DW MR imaging (b = 0, 20 and 150 s/mm{sup 2}) and were analysed by two independent readers. Histological examination was performed on 0.4-mm slices. McNemar's test was used to compare the sensitivities and the Wilcoxon matched pairs test to compare the average number of false-positives per rat. One hundred and sixty-six liver metastases were identified on histological examination. The sensitivity in detecting liver metastases was significantly higher on DW MR than on T2-weighted images (99/166 (60 %) (reader 1) and 92/166 (55 %) (reader 2) versus 77/166 (46 %), P {<=} 0.001), without an increase in false-positives per rat (P = 0.773/P = 0.850). After stratification according to metastasis diameter, DW MR imaging had a significantly higher sensitivity than T2-weighted imaging only for metastases with a diameter (0.6-1.2 mm) similar to that of the spatial resolution of MR imaging in the current study. This MR study with histological correlations shows the higher sensitivity of DW relative to T2-weighted imaging at 7 T for detecting liver metastases, especially small ones. (orig.)

    1. The pharmacokinetics of mitomycin C (MMC) was evaluated during hypoxic hepatic infusion (HHMI) with arterial embolization for the treatment of unresectable liver metastases. 2. Ten patients with hepatic metastases from colorectal cancer were considered. Antiblastic infusion with MMC (20 mg/m2 at 30 ml/min) was initiated after 10 min of hepatic arterial occlusion. Peripheral venous blood samples were collected at different time intervals. MMC was assayed by high-pressure liquid chromatography (HPLC), and pharmacokinetic parameters were determined using an open, two-compartment model and linear kinetics. 3. Cmax of MMC during HHMI was 708 +/- 336.6 ng/ml, and tmax was 9.3 +/- 1.1 min. The plasma concentration-time curve showed a t1/2 alpha ranging from 1.5 to 9 min, followed by a t1/2 beta ranging from 31 to 93 min. The Cltot was 35.5 l/h/m2 with an area under the plasma concentration-time curve (AUC) ranging from 251 to 850 micrograms h/l. The same AUC parameter standardized for the amount of MMC was 15.5 mg-1. The HHMI model that we used revealed a significant increase in Cltot and a reduction in AUC when compared to the locoregional intraarterial and peripheral intravenous models (p < .001). 4. The reduction in AUC following HHMI explains the limited systemic toxicity in treated patients, with a greater total tumor exposure to the drug and improved drug activation.

    Objective This review discusses the current status and progress in studies on gastric cancer with liver metastasis (GCLM), involving the routes, subtypes, and prognosis of GCLM; the genes and molecules associated with metastasis;the feasibility and value of each imaging modality; and current treatment options.Data sources The data used in this review were mainly from Medline and PubMed published in English from 2005 to August 2010. The search terms were "gastric cancer" and "liver metastasis".Study selection Articles regarding the characteristics, diagnostic modalities, and vadous therapeutic options of GCLM were selected.Results The prognosis of GCLM is influenced by the clinicopathological characteristics of primary tumors, as well as the presence of liver metastases. Improved understanding of related genes and molecules will lead to the development of methods of early detection and targeted therapies. For the diagnosis of GCLM, each imaging modality has its relative benefits. There remains no consensus regarding therapeutic options.Conclusions Early detection and characterization of liver metastases is crucial for the prognosis of gastric cancer patients. Multidisciplinary team discussions are required to design optimal treatment strategies, which should be based on the clinicopathological characteristics of each patient.

    Renal cell cancer rarely metastasizes to the thyroid gland, and it has been reported to present as a solitary mass. We present a case of diffuse thyroid cancer metastases from renal cell cancer. Bilateral internal jugular vein tumor thrombi were also present. To the best of our knowledge, this is the first description of diffuse thyroid metastases from renal cell cancer in the English literature. Renal cell cancer metastases should be considered in the differential of thyroid imaging abnormalities arising in the setting of known renal cell carcinoma, particularly late in the course of disease. This is frequently associated with internal jugular vein thrombi, which should be evaluated with an abnormal thyroid. Thyroglobulin levels are usually normal in such patients.

    Improvements in imaging technology allow exploitation of the dual blood supply of the liver to aid in the identi-fication and characterisation of both malignant and benign liver lesions. Imaging techniques available include contrast enhanced ultrasound, computed tomography and magnetic resonance imaging. This review discusses the application of several imaging techniques in the diagnosis and staging of both hepatocellular carcinoma and cholangiocarcinoma and outlines certain characteristics of benign liver lesions. The advantages of each imaging technique are highlighted, while underscoring the potential pitfalls and limitations of each imaging modality.

    AIM: To explore the feasibility of computed tomography (CT)-guided percutaneous ethanol injection (PEI) using a disposable curved needle for treatment of malignant liver neoplasms and their metastases in retroperitoneal lymph nodes.METHODS: CT-guided PEI was conducted using a disposable curved needle in 26 malignant liver tumors smaller than 5 cm in diameter and 5 lymph node metastases of liver cancer in the retroperitoneal space. The disposable curved needle was composed of a straight trocar (21G) and stylet, a disposable curved tip (25 G) and a fine stylet. For the tumors found in deep sites and difficult to reach, or for hepatic masses inaccessible to the injection using a straight needle because of portal vein and bile ducts, the straight trocar was used at first to reach the side of the tumor. Then, the disposable curved needle was used via the trocar. When the needle reached the tumor center, appropriate amount of ethanol was injected. For relatively large malignant liver tumors,multi-point injection was carried out for a better distribution of the ethanol injected throughout the masses. The curved needle was also used for treatment of the metastasis in retroperitoneal lymph nodes blocked by blood vessels and inaccessible by the straight needle.RESULTS: All of the 26 liver tumors received 2 or more times of successful PEI, through which ethanol was distributed throughout the whole tumor mass. Effect of the treatment was monitored by contrast-enhanced multi-phase CT and magnetic resonance imaging (MRI) examinations three months later. Of the 18 lesions whose diameters were smaller than 3 cm, the necrotic change across the whole mass and that in most areas were observed in 15 and 3 tumors,respectively. Among the 8 tumors sizing up to 3 cm, 5 were completely necrotic and 3 largely necrotic. Levels of tumor seromarkers were significantly reduced in some of the cases.In 5 patients with metastases of liver cancer in retroperitoneal lymph nodes who received 1 to 3

    The immune response influences the clinical course of colorectal cancer (CRC). Analyzing the invasive margin of human CRC liver metastases, we identified a mechanism of immune cell exploitation by tumor cells. While two distinct subsets of myeloid cells induce an influx of T cells into the invasive margin via CXCL9/CXCL10, CCL5 is produced by these T cells and stimulates pro-tumoral effects via CCR5. CCR5 blockade in patient-derived functional in vitro organotypic culture models showed a macrophage repolarization with anti-tumoral effects. These anti-tumoral effects were then confirmed in a phase I trial with a CCR5 antagonist in patients with liver metastases of advanced refractory CRC. Mitigation of tumor-promoting inflammation within the tumor tissue and objective tumor responses in CRC were observed.

    2012-02-03

    In clinical radiology, there are numerous examples of new techniques that were initially enthusiastically promoted and then subsequently abandoned when early promise was not realized in routine patient care. Appropriateness of new or established interventional radiology techniques to specific clinical conditions must be determined from clinical experience, from communication with experts in the field and\\/or careful review of available medical literature, and on an individual patient basis by means of review of clinical notes and diagnostic imaging studies. For patients with liver neoplasms, regional techniques such as radiofrequency ablation (RFA) have been developed and are now the subject of ongoing research. This article describes the utilization of Evidence-Based Practice (EBP) techniques as a means of deciding the appropriateness of percutaneous RFA in treating colorectal liver metastases (CLM).

    Full Text Available Radioembolisation is a way of providing targeted radiotherapy to colorectal liver metastases. Results are encouraging but there is still no standard method of assessing the response to treatment. This paper aims to review the current experience assessing response following radioembolisation. A literature review was undertaken detailing radioembolisation in the treatment of colorectal liver metastases comparing staging methods, criteria, and response. A search was performed of electronic databases from 1980 to November 2011. Information acquired included year published, patient numbers, resection status, chemotherapy regimen, criteria used to stage disease and assess response to radioembolisation, tumour markers, and overall/progression free survival. Nineteen studies were analysed including randomised controlled trials, clinical trials, meta-analyses, and case series. There is no validated modality as the method of choice when assessing response to radioembolisation. CT at 3 months following radioembolisation is the most frequently modality used to assess response to treatment. PET-CT is increasingly being used as it measures functional and radiological aspects. RECIST is the most frequently used criteria. Conclusion. A validated modality to assess response to radioembolisation is needed. We suggest PET-CT and CEA pre- and postradioembolisation at 3 months using RECIST 1.1 criteria released in 2009, which includes criteria for PET-CT, cystic changes, and necrosis.

    The biology of colorectal cancer differs according to itsitss location within the large intestine. A report publishedinpublished inin a previous issue of World Journal of Gastroenterology (November 2010) evaluated the importance of tumor location as a risk factor for lymph node metastasis in colorectal cancer, and showed that rectal cancer is prone to metastasize to lymph nodes as compared with colon cancer. However, in order to conclude that the tumor location is independently associated with the occurrence of lymph node metastasis, it is necessary to consider a selection bias or other patient- and tumor-related factors carefully.

    1983-05-01

    In 15 out of 20 cases of hepatic metastases with calcication, the primary focal lesion was found to be colonic cancer (10 of which were rectal cancer). The rate of calcification of metastatic liver lesions from colorectal cancer was as high as 17.9%. According to pathological classification, the primary lesion was a differentiated adenocarcinoma in 16 cases. Calcification was found to be large and to have a tendency to occur more easily in a person with multiple metastatic liver lesions. The forms of calcification from ''disperse punctate''- ''collective punctate''-''central mass''-to'' vermicular'' were inferred to represent the changes in development of the calcification.

    . In this study, we explored how TNF signaling influences the efficiency of liver metastasis by colon and lung carcinoma in mice that are genetically deficient for the TNF receptor TNFR2. We found a marked reduction in liver metastases that correlated with a greatly reduced accumulation at metastatic sites of CD......11b(+)GR-1(+) myeloid cells with enhanced arginase activity, identified as myeloid-derived suppressor cells (MDSC). Reduced infiltration of MDSC coincided with a reduction in the number of CD4(+)FoxP3(+) T regulatory cells in the tumors. Reconstitution of TNFR2-deficient mice with normal bone marrow......, or adoptive transfer of TNFR2-expressing MDSC into these mice, was sufficient to restore liver metastasis to levels in wild-type mice. Conversely, treatment with TNFR2 antisense oligodeoxynucleotides reduced liver metastasis in wild-type mice. Clinically, immunohistochemical analysis of liver metastases from...

  11. The features of peritoneal metastases from gastric cancer

    2016-01-01

    Peritoneal Carcinomatosis (PC) from metastasization of Gastric Cancer (GC), either present at ifrst diagnosis of GC or as recurrence, is considered a fatal disease with no hope of deifnitive cure. Although newer agents like S1 and docetaxel have shown some promise, the median overall survival with the current ifrst line chemotherapy is only 8 to 14 months, and is not greatly improved by adding targeted therapy. A multi-modal approach with cytoreductive surgery (CRS) associated with hyperthermic intraperitoneal chemotherapy (HIPEC) has been developed along the last two decades in order to tackle this problem. It’s an aggressive, combined treatment still under investigation. Studies coming from Europe and Far East reported long-term survival with 5-year survival rates up to nearly 25% in case of complete cytoreduction. Prophylactic/adjuvant setting is the most evidence-based indication for HIPEC in advanced-stage GC patients without PC, in order to prevent peritoneal recurrence and to improve overall survival. The rationale for immuno treatment in patients with gastric PC is strong. A randomized phase II study, combining complete CRS with intraperitoneal catumaxomab is on-going. The detection of free peritoneal cancer cells is the more realistic and practical way for the identiifcation of patients at risk of carcinomatosis after surgery. The routine use of techniques of molecular detection in peritoneal washing appears to be the more sensitive method. Such patients are potential candidate for multimodal and locoregional treatments in order to prevent the peritoneal recurrence.

    Full Text Available BACKGROUND: Brain metastases occur commonly in patients with lung cancer. Small vessel ischemic disease is frequently found when imaging the brain to detect metastases. We aimed to determine if the presence of small vessel ischemic disease (SVID of the brain is protective against the development of brain metastases in lung cancer patients. METHODOLOGY/PRINCIPAL FINDINGS: A retrospective cohort of 523 patients with biopsy confirmed lung cancer who had received magnetic resonance imaging of the brain as part of their standard initial staging evaluation was reviewed. Information collected included demographics, comorbidities, details of the lung cancer, and the presence of SVID of the brain. A portion of the cohort had the degree of SVID graded. The primary outcome measure was the portion of study subjects with and without SVID of the brain who had evidence of brain metastases at the time of initial staging of their lung cancer.109 patients (20.8% had evidence of brain metastases at presentation and 345 (66.0% had evidence of SVID. 13.9% of those with SVID and 34.3% of those without SVID presented with brain metastases (p<0.0001. In a model including age, diabetes mellitus, hypertension, hyperlipidemia, and tobacco use, SVID of the brain was found to be the only protective factor against the development of brain metastases, with an OR of 0.31 (0.20, 0.48; p<0.001. The grade of SVID was higher in those without brain metastases. CONCLUSIONS/SIGNIFICANCE: These findings suggest that vascular changes in the brain are protective against the development of brain metastases in lung cancer patients.

    A highly individualized stereotactic body radiotherapy (SBRT) strategy was developed to allow a wide spectrum of patients with liver cancer to be treated. This phase I/II study encompasses individualization of immobilization, radiation planning, PTV margin determination, image guidance strategy and prescription dose. Active breathing control breath hold is used to immobilize the liver when feasible. Image guidance strategies include orthogonal MV images and orthogonal kV fluoroscopy using the diaphragm for a surrogate for the liver, and kV cone beam CT using the liver or tumour for guidance. The prescription dose is individualized to maintain the same estimated risk of radiation-induced liver disease (RILD), based on a normal tissue complication probability (NTCP) model, with a maximum permitted dose of 60 Gy in 6 fractions. Since August 2003, 79 patients with hepatocellular carcinoma (33), intrahepatic cholangiocarcinoma (12) and liver metastases (34) were treated. The median tumour volume was 293 cm{sup 3} (2.9-3088 cm{sup 3}). The median prescribed dose was 36.6 Gy (24.0 Gy-57.0 Gy) in 6 fractions. The median effective liver volume irradiated was 45% (9-80%). Sixty percent of patients were treated with breath hold to immobilize their liver. Intra-fraction reproducibility (s) of the liver with repeat breath holds was excellent (1.5?mm); however inter-fraction reproducibility (s) was worse (3.4 mm). Image guidance reduced the residual systematic and random setup errors significantly.

    We report the case of a 69-year-old male patient with diagnoses of sigmoid colon cancer, ascending colon cancer, and metastatic liver cancer. We performed sigmoidectomy, right hemicolectomy, and central venous port placement. Because the liver metastasis was multifocal, chemotherapy was first initiated and then hepatic resection was performed. However, during chemotherapy, ileus, with a peritoneal dissemination to the small intestine, developed. Small intestine resection and radiation therapy to the pelvic region of the transition were further performed. Thereafter, obstructive jaundice due to obstruction of the bile duct in the hilar area developed, and therefore, we inserted a biliary stent. However, 2 years 9 months after the first medical examination, this patient died of colon cancer. The guidelines above, still chemotherapy developed, treatment policy of recurrent colorectal cancer, have recommended surgical resection with respect to what resectable as local therapy. This case shows that combination therapy with chemotherapy, surgical therapy, radiation therapy, and local therapy such as biliary stenting, is useful.

    Full Text Available Knowledge on lymph node metastases is crucial for the prognosis and treatment of prostate cancer patients. Conventional anatomic imaging often fails to differentiate benign from metastatic lymph nodes. Pelvic lymph node dissection is an invasive technique and underestimates the extent of lymph node metastases. Therefore, there is a need for more accurate non-invasive diagnostic techniques. Molecular and functional imaging has been subject of research for the last decades, in this respect. Therefore, in this article the value of imaging techniques to detect lymph node metastases is reviewed. These techniques include scintigraphy, sentinel node imaging, positron emission tomography/computed tomography (PET/CT, diffusion weighted magnetic resonance imaging (DWI MRI and magnetic resonance lymphography (MRL. Knowledge on pathway and size of lymph node metastases has increased with molecular and functional imaging. Furthermore, improved detection and localization of lymph node metastases will enable (focal treatment of the positive nodes only.

These techniques include scintigraphy, sentinel node imaging, positron emission tomography/computed tomography (PET/CT), diffusion weighted magnetic resonance imaging (DWI MRI) and magnetic resonance lymphography (MRL). Knowledge on pathway and size of lymph node metastases has increased with molecular and functional imaging. Furthermore, improved detection and localization of lymph node metastases will enable (focal) treatment of the positive nodes only.

    Serotype K1 Klebsiella pneumoniae is a major cause of liver abscesses and endophthalmitis. This study was designed to identify the role of neutrophils in the development of distant metastatic complications that were caused by serotype K1 K. pneumoniae. An in vitro cellular model was used to assess serum resistance and neutrophil-mediated killing. BALB/c mice were injected with neutrophils containing phagocytosed K. pneumoniae. Serotype K1 K. pneumoniae was significantly more resistant to serum killing, neutrophil-mediated phagocytosis and intra-cellular killing than non-K1 isolates (pneutrophils containing phagocytosed serotype K1 K. pneumoniae led to abscess formation in multiple sites including the subcutaneous tissue, lung, and liver, whereas no abscess formation was observed in mice injected with non-K1 isolates. The resistance of serotype K1 K. pneumoniae to complement- and neutrophil-mediated intracellular killing results in the dissemination of K. pneumoniae via the bloodstream. Escape from neutrophil intracellular killing may contribute to the dissemination and establishment of distant metastases. Thus, neutrophils play a role as a vehicle for helping K. pneumoniae and contributing to the establishment of liver abscess and distant metastatic complications.

    Full Text Available BACKGROUND: It remains unclear which patients can benefit from simultaneous resection of synchronous colorectal liver metastases (SCRLMs. This study aimed to examine the prognostic value of patient- and tumor-related factors in predicting long-term outcomes of patients undergoing simultaneous resection of SCRLMs and to help patients select a suitable therapeutic regimen and proper surveillance. METHODS: Clinicopathological and outcome data of 154 consecutive SCRLM patients who underwent simultaneous resection between July 2003 and July 2013 were collected from our prospectively established SCRLM data and analyzed with univariate and multivariate methods, and the prognostic index (PI was formulated based on the regression coefficients (β of the Cox model. The patients were classified into high- and low-risk groups according to the PI value; the cut-off point was the third quartile. RESULTS: The 5-year overall survival rate was 46%, and the 5-year disease-free survival rate was 35%. Five factors were found to be independent predictors of poor overall survival (OS by multivariate analysis: positive lymph node status, vascular invasion, BRAF mutation, the distribution of bilobar liver metastases (LMs and non-R0 resection of LMs. Compared to low PI (≤5.978, high PI (>5.978 was highly predictive of shorter OS. Three factors were found to be independent predictors of poor disease-free survival (DFS by multivariate analysis: tumor deposits, BRAF mutation and bilobar LM distribution. We also determined the PI for DFS. Compared to low PI (≤2.945, high PI (>2.945 was highly predictive of shorter DFS. CONCLUSIONS: Simultaneous resection of SCRLM may lead to various long-term outcomes. Patients with low PI have longer OS and DFS, while those with high PI have shorter OS and DFS. Thus, patients with high PI may receive more aggressive treatment and intensive surveillance, This model needs further validation.

    Distant metastases of differentiated thyroid cancer are unusual; lung and bones are the most frequently affected sites. Soft tissue metastases (STM) are extremely rare. We describe two cases of patients with differentiated thyroid cancer metastasizing to soft tissues. Both patients had widespread metastatic disease; clinically asymptomatic soft tissue metastases were found by 18-Fluorodeoxyglucose positron emission tomography/computed tomography ({sup 18}F FDG PET-CT), and confirmed by cytological and/or histopathological studies. These findings underscore the ability of {sup 18}F FDG PET-CT in accurately assessing the extent of the disease, as well as the utility of the method to evaluate regions of the body that are not routinely explored.

    We managed 6 cases of severe liver atrophy and failure associated with paclitaxel and bevacizumab combination therapy (PB therapy)for HER2-negative metastatic breast cancer. In this case-controlstudy, we examined the records of these 6 patients to investigate past treatment, medication history, and degree of atrophy, and compared their data with that of 67 patients without liver atrophy. The degree of the liver atrophy used SYNAPSE VINCENT®of the image analysis software. The results showed that patients with liver atrophy had a longer pretreatment period than those without liver atrophy(33.5 months vs 15.5 months), and they also experienced a longer median time to treatment failure with PB therapy than other patients(11 months vs 6 months). The ratio of individuals presenting with diffuse liver metastasis among patients with liver metastasis was 80% with liver atrophy, compared to 8% without liver atrophy. The degree of liver atrophy was an average of 67%in terms of volume ratio before/after PB therapy(57-82%). The individualwith the greatest extent of liver atrophy died of liver failure, not as a result of breast cancer progression. The direct causal link between bevacizumab and liver atrophy and failure is unclear, but the individuals in this study had a long previous history of treatment, and diffuse liver metastases may develop in patients undergoing long periods of PB therapy, which may also cause liver atrophy; therefore, the possibility of liver failure should be considered in such cases.

    Prostate cancer is the most common primary tumor in men, with a high propensity to metastasize to bone. Bone metastases in prostate cancer are associated with active pathologic bone remodeling, leading to increased mortality and morbidity. Detailed characterization of bone metastases is important in the management of prostate cancer. Raman spectroscopy was applied in this study to investigate the structure and composition of metastatic bone in prostate cancer with the ultimate goal of identifying spectral features that are related to the alterations in bone quality as the bone metastases develop. Osteoblastic-, osteolytic- and tumor-absent bone specimens from prostate cancer patients were investigated using bench-top Raman microspectroscopy. Raman derived measurements of collagen mineralization, mineral crystallinity, and carbonate substitution were calculated. The osteolytic lesions demonstrated significantly lower collagen mineralization, determined by phosphate ν1/proline, and higher carbonate substitution than normal and osteoblastic bones. Mineral crystallinity was significantly lower in both blastic and lytic specimens. In addition, a significant increase in the ratio of hydroxyproine: proline was observed in the osteoblastic specimen, indicating an increase in the content of hydroxyproline at the blastic lesions. This study demonstrate that Raman spectroscopy shows promise in determining alterations in osteoblastic and osteolytic bone metastases as well as assessing the response of metastatic bone to therapies.

    In a prospective multicenter phase II trial of radioembolization with yttrium-90 ((90)Y-RE) in chemorefractory liver-dominant metastatic colorectal cancer (mCRC), we showed that median survival was 12.6 months (95% CI 7.0-18.3) with 48% of 50 patients achieving disease control. In this extension retrospective study, we analyzed whether a panel of biomarkers, known to be associated to an adverse clinical outcome, underwent variations in CRC liver metastases pre and post (90)Y-RE.Of the 50 patients included in the study, 29 pre-(90)Y-RE therapy and 15 post-(90)Y-RE had liver biopsy specimens available. In these series we investigated survivin, p53, Bcl-2 and Ki-67 expression pre- and post-(90)Y-RE by immuhistochemistry (IHC). Our findings evidenced a decrease of survivin (77% vs 33%), p53 (93% vs 73%), Bcl-2 (37% vs 26%) expression as well as of Ki-67 proliferation index (62.5% vs 40%) on liver biopsies collected post-(90)Y-RE as compared to pre-(90)Y-RE. In the subset of 13 matched liver metastases we further confirmed the reduction of survivin (92.3% vs 53.8%; p = 0.06), p53 (100% vs 69.2%; p = 0.05) and Bcl-2 (69.2% vs 53.8%; p = 0.05) expression post-(90)Y-RE. This biomarker modulation was accompanied by morphological changes as steatohepatitis, hepatocyte necrosis, collagen deposition, proliferating and/or bile duct ectasia, focal sinusoidal dilatation and fibrosis.Although our analysis was conducted in a very limited number cases, these changes appear strictly related to the response to (90)Y-RE therapy and may deserve further investigation on a larger series of patients.

    Selection criteria and benefit of liver transplantation for hepatic metastases from neuroendocrine tumors (NETs) remains uncertain. Eighty-eight consecutive patients with metastatic NETs eligible for liver transplantation according to Milan-NET criteria were offered transplant (n.42) vs. non-transplant options (n.46) depending on list dynamics, patient disposition and age. Tumor burden between groups did not differ. Transplant patients were younger (40.5 vs. 55.5 years; p<0.001). Long-term outcomes were compared after matching between groups made on multiple Cox models adjusted for propensity score built on logistic models. Survival-benefit was the difference in mean survival between transplant vs. non-transplant options. No patients were lost or died without recurrence. Median follow-up was 122 months. Transplant group showed significant advantage over non-transplant strategies at 5 and 10-yrs in survival (97.2% and 88.8% vs. 50.9% and 22.4% respectively; p<0.001) and time-to-progression (13.1% and 13.1% vs. 83.5% and 89%; p<0.001). After adjustment for propensity score, survival advantage of transplant group was significant (HR=7.4; 95%CI: 2.4-23.0; p=0.001). Adjusted transplant-related survival-benefit was 6.82 months (95%CI: 1.10-12.54; p=0.019) and 38.43 months (95%CI: 21.41-55.45; p<0.001) at 5 and 10-yrs respectively. Liver transplantation for metastatic NETs under restrictive criteria provides excellent long-term outcome. Transplant-related survival-benefit increases over time and maximizes after 10 yrs.

    To determine the best predictor for the response to and survival with transarterial radioembolisation (RE) with {sup 90}yttrium microspheres in patients with liver metastases. Forty consecutive patients with liver metastases undergoing RE were evaluated with multiphase CT, perfusion CT and {sup 99m}Tc-MAA SPECT. Arterial perfusion (AP) from perfusion CT, HU values from the arterial (aHU) and portal venous phase (pvHU) CT, and {sup 99m}Tc-MAA uptake ratio of metastases were determined. Morphologic response was evaluated after 4 months and available in 30 patients. One-year survival was calculated with Kaplan-Meier curves. We found significant differences between responders and non-responders for AP (P < 0.001) and aHU (P = 0.001) of metastases, while no differences were found for pvHU (P = 0.07) and the {sup 99m}Tc-MAA uptake ratio (P = 0.40). AP had a significantly higher specificity than aHU (P = 0.003) for determining responders to RE. Patients with an AP >20 ml/100 ml/min had a significantly (P = 0.01) higher 1-year survival, whereas an aHU value >55 HU did not discriminate survival (P = 0.12). The Cox proportional hazard model revealed AP as the only significant (P = 0.02) independent predictor of survival. Compared to arterial and portal venous enhancement and the {sup 99m}Tc-MAA uptake ratio of liver metastases, the AP from perfusion CT is the best predictor of morphologic response to and 1-year survival with RE.

    Primary liver cancer (hepatocellular carcinoma, or HCC) is associated with liver cirrhosis 60-80% of the time. Liver cancer is one of the most common malignancies in the world, with approximately 1,000,000 cases reported every year. About 80% of people with primary liver cancer are male. Although two-thirds of people have advanced liver disease when they seek medical help, one third of the patients have cancer that has not progressed beyond the liver. HCC may metastasize to the lung, bones, kidney, and many other organs. Surgical resection, liver transplantation, chemotherapy and radiation therapy are the foundation of current HCC therapies. However the outcomes are poor: the survival rate is almost zero for metastatic HCC patients. Molecular mechanisms of HCC metastasis need to be understood better and new therapies must be developed to selectively target to unique characteristics of HCC cell growth and metastasis. We have developed the "in vivo microscopy" to study the mechanisms that govern liver tumor cell spread through the microenvironment in vivo with real-time confocal near-infrared fluorescence imaging. A recently developed "in vivo flow cytometer" and optical imaging are used to assess liver tumor cell spreading and the circulation kinetics of liver tumor cells. A real- time quantitative monitoring of circulating liver tumor cells by the in vivo flow cytometer will be useful to assess the effectiveness of the potential therapeutic interventions.

    Full Text Available Medications increasing the survival of patients with metastatic castration-refractory prostate cancer (CRPC are lacking today. In the past 3 years, in the pharmaceutical market there have been a few novel drugs to treat progressive prostate cancer. Abiraterone acetate is an androgen synthesis inhibitor, which is also used to increase the survival of patients with metastatic CRPC that progresses after chemotherapy. The results of treatment for metastatic CRPC depend on a number of factors. Visceral metastases are poor predictors of the course of the disease. The results of abiraterone acetate treatment were analyzed in CRPC patients with visceral metastases.

With the advent of improved imaging techniques and screening programmes, only a small proportion of women present with metastatic disease. Metastases involving the gastrointestinal (GI tract and orbit are rare occurrences. We describe the case of a woman with simultaneous GI and orbital metastases from breast cancer who initially presented with abdominal pain and blurred vision and also summarise a review of the literature.

    Full Text Available Background and Aims: Insulin-like growth factor-I (IGF-1 is a liver-derived humoral factor, which has important anabolic and metabolic actions. Low serum concentrations of IGF-1 have been reported in patients with chronic liver disease, especially cirrhosis and hepatocellular carcinoma and metastatic liver cancer. The aim of our study was to evaluate any possible relationship between intensity of liver metastases on serum IGF-1 concentrations. Methods: Serum IGF-1 were measured by ELIZA (III in10 patients with uninodular or multinodular liver metastases and extension |£50% (group A and 10 patients with multinodular or massive liver metastases and extension > 50% (group B of liver size without liver failure.Results: Serum IGF-1 concentration was significantly lower in the more sever metastatic group (group B than the less sever metastatic group (group A (121.40 ± 52.08 vs. 210.30 ± 42.59 ng/ml, respectively; P < 0.001.Conclusions: Our findings suggest that the states of serum IGF-1 levels in patients with metastatic liver cancer may be a helpful finding for determining the severity of metastasis to the liver.

    The purpose of this study was to investigate differences in change of size and CT value between local recurrences and tumor-free areas after CT-guided radiofrequency ablation (RFA) of hepatic metastases during follow-up by means of dedicated software for automatic evaluation of hepatic lesions. Thirty-two patients with 54 liver metastases from breast or colorectal cancer underwent triphasic contrast-enhanced multidetector-row computed tomography (MDCT) to evaluate hepatic metastatic spread and localization before CT-guided RFA and for follow-up after intervention. Sixteen of these patients (65.1 + or - 10.3 years) with 30 metastases stayed tumor-free (group 1), while the other group (n = 16 with 24 metastases; 62.0 + or - 13.8 years) suffered from local recurrent disease (group 2). Applying an automated software tool (SyngoCT Oncology; Siemens Healthcare, Forchheim, Germany), size parameters (volume, RECIST, WHO) and attenuation were measured within the lesions before, 1 day after, and 28 days after RFA treatment. The natural logarithm (ln) of the quotient of the volume 1 day versus 28 days after RFA treament was computed: lnQ1//28/0(volume). Analogously, ln ratios of RECIST, WHO, and attenuation were computed and statistically evaluated by repeated-measures ANOVA. One lesion in group 2 was excluded from further evaluation due to automated missegmentation. Statistically significant differences between the two groups were observed with respect to initial volume, RECIST, and WHO (p free and local-recurrent ablation zones with respect to the corresponding size parameters. A new parameter (lnQ1//28/0(volume/RECIST/WHO/attenuation)) was introduced, which appears to be of prognostic value at early follow-up CT.

    Purpose: To assess the value of multiphase-subtraction-CT for early detection of colorectal-liver-metastases (CRLM). Methods and materials: In 50 patients suspected of CRLM a routine pre-operative 4-phase-CT-scan of the upper abdomen was obtained. All 12 possible image subtractions between two different phases were constructed applying 3D-image-registration to decrease distortion artefacts induced by differences in inspiration volume. Two experienced radiologists initially reviewed the conventional 4-phase-CT for malignant and/or benign appearing lesions and at least 1-month hereafter the same 4-phase-CT now including the subtracted images. The results were compared to histology reports or to a combination of surgical exploration and intraoperative ultrasound together with results from pre-operative PET and follow-up examinations. Results: Although an additional number of 31 malignant appearing lesions were detected on the subtraction images, none proved to represent a true CRLM. Interobserver agreement ({kappa}) decreased from 0.627 (good) to 0.418 (fair). Conclusion: Adding linearly co-registered subtraction-CT images to a conventional 4-phase-CT protocol does not improve detection of CRLM.

    Full Text Available Aim of study: To investigate the features, adverse effects, bone marker changes in patients with breast cancer, prostate cancer, and multiple myeloma with bone metastases under Zometa® therapy. Materials and Methods: This post-marketing study included 414 Taiwanese patients with bone metastases secondary to breast cancer, prostate cancer, or multiple myeloma who received Zometa® for 48 weeks. The patients′ characteristics, medication and adverse events were recorded, meanwhile changes in four serum bone metabolic markers and pain reduction were assessed every three months for one year. Results: A total of 3,711 doses of Zometa® were infused, accounting for 294.5 patient-years. Adverse events occurred in 9.4% of patients, with bone pain, insomnia, constipation, and pyrexia as the most frequently reported. There was no osteonecrosis of the jaw. The incidence of skeletal-related events decreased significantly from 44.9% to 18.8%. Serum NTx, BAP, and TRACP5b steadily decreased to nadir at six months, but serum OPG was persistently elevated until the end of one year. The average decrease in pain score was 14.1, 14.3, and 16.7 for prostate cancer, breast cancer, and multiple myeloma patients, respectively. Conclusion: Zometa® can be safely administered in Taiwanese patients with bone metastases secondary to breast cancer, prostate cancer, and multiple myeloma. There are concomitant decreases in skeletal-related events and bone pain.

    To obtain the diagnostic performance of diffusion-weighted (DW) and gadoxetic-enhanced magnetic resonance (MR) imaging in the detection of liver metastases. A comprehensive search (EMBASE, PubMed, Cochrane) was performed to identify relevant articles up to June 2015. Inclusion criteria were: liver metastases, DW-MR imaging and/or gadoxetic acid-enhanced MR imaging, and per-lesion statistics. The reference standard was histopathology, intraoperative observation and/or follow-up. Sources of bias were assessed using the QUADAS-2 tool. A linear mixed-effect regression model was used to obtain sensitivity estimates. Thirty-nine articles were included (1,989 patients, 3,854 metastases). Sensitivity estimates for DW-MR imaging, gadoxetic acid-enhanced MR imaging and the combined sequence for detecting liver metastases on a per-lesion basis was 87.1 %, 90.6 % and 95.5 %, respectively. Sensitivity estimates by gadoxetic acid-enhanced MR imaging and the combined sequence were significantly better than DW-MR imaging (p = 0.0001 and p < 0.0001, respectively), and the combined MR sequence was significantly more sensitive than gadoxetic acid-enhanced MR imaging (p < 0.0001). Similar results were observed in articles that compared the three techniques simultaneously, with only colorectal liver metastases and in liver metastases smaller than 1 cm. In patients with liver metastases, combined DW-MR and gadoxetic acid-enhanced MR imaging has the highest sensitivity for detecting liver metastases on a per-lesion basis. (orig.)

    The role of the immune system in the course of colorectal cancer has been elucidated in the last decade. While quantification of immune cell infiltrates within the resected specimen at diagnosis has a clear power to estimate the prognosis of the patient, the role of infiltrating immune cells within the metastatic situation and especially within the metastatic lesion itself requires further detailed analyses. Recent analyses of infiltrates in colorectal cancer liver metastases revealed a role for the infiltrate density not only for prognosis but also in the prediction of treatment response. This not only broadens the view on these infiltrates and indicates a systematic role of the local immunological microenvironment, but also raises the question how these infiltrates change during repeated courses of treatment (i.e., resection, chemotherapy, etc.). To address this question, sequential lung or sequential liver metastases of colorectal cancer patients were analyzed using whole slide image quantification after immunohistochemical staining against CD3, CD8, FOXP3, CD68 and Granzyme B. The clinical data and interventions were associated with each individual patient and the metastatic lesions. The resulting cell densities reveal a heterogeneous profile: after successful treatment of a metastatic lesion, the recurrent lesion can still have the same immunophenotype with similar cell distributions. In a situation of a favorable immune cell profile, this profile can return and apparently convey a similar favorable course throughout the disease. But also the opposite was found: the recurrent metastatic lesion could have a different profile with alterations in specific immune cell subsets over time. Further analyses are required to elucidate the different patterns and their associations to the treatment, the tumor cell phenotype and other dynamic factors. However, it is clear from this data however, that there is an immune cell plasticity that needs to be analyzed for

    Lung metastasis is the major cause of death in patients with triple negative breast cancer (TNBC), an aggressive subtype of breast cancer with no effective therapy at present. It has been proposed that dual-targeted therapy, ie, targeting chemotherapeutic agents to both tumor vasculature and cancer cells, may offer some advantages. The present work was aimed to develop a dual-targeted synergistic drug combination nanomedicine for the treatment of lung metastases of TNBC. Thus, Arg-Gly-Asp peptide (RGD)-conjugated, doxorubicin (DOX) and mitomycin C (MMC) co-loaded polymer-lipid hybrid nanoparticles (RGD-DMPLN) were prepared and characterized. The synergism between DOX and MMC and the effect of RGD-DMPLN on cell morphology and cell viability were evaluated in human MDA-MB-231 cells in vitro. The optimal RGD density on nanoparticles (NPs) was identified based on the biodistribution and tumor accumulation of the NPs in a murine lung metastatic model of MDA-MB-231 cells. The microscopic distribution of RGD-conjugated NPs in lung metastases was examined using confocal microscopy. The anticancer efficacy of RGD-DMPLN was investigated in the lung metastatic model. A synergistic ratio of DOX and MMC was found in the MDA-MB-231 human TNBC cells. RGD-DMPLN induced morphological changes and enhanced cytotoxicity in vitro. NPs with a median RGD density showed the highest accumulation in lung metastases by targeting both tumor vasculature and cancer cells. Compared to free drugs, RGD-DMPLN exhibited significantly low toxicity to the host, liver and heart. Compared to non-targeted DMPLN or free drugs, administration of RGD-DMPLN (10 mg/kg, iv) resulted in a 4.7-fold and 31-fold reduction in the burden of lung metastases measured by bioluminescence imaging, a 2.4-fold and 4.0-fold reduction in the lung metastasis area index, and a 35% and 57% longer median survival time, respectively. Dual-targeted RGD-DMPLN, with optimal RGD density, significantly inhibited the progression of

    Fluor-18-deoxyglucose-positron emission tomography (FDG-PET) has emerged as a promising diagnostic modality in recurrent colorectal carcinoma. Whole-body FDG-PET may be an accurate diagnostic modality to determine whether patients with recurrent hepatic disease are suitable candidates for curative resection. Reports on the use of FDG-PET in patients with recurrent colorectal carcinoma are scarce, especially those on colorectal liver metastases. To assess the usefulness of this emerging modality for the selection of patients to undergo resection for colorectal liver metastases, a systematic (meta)-analysis of the current literature was conducted. In the absence of randomized controlled clinical trials, a traditional meta-analysis could not be performed. An alternative strategy was designed to evaluate the current literature. After a literature search, an index score was devised to evaluate the articles with regard to the impact of FDG-PET in patients with colorectal liver metastases. The index scored articles on several items and, as such, could be considered an objective approach for the assessment of diagnostic, nonrandomized clinical trials. The proposed index proved to be an independent instrument for judging several research questions and was used systematically to address the sensitivity, specificity, and clinical impact of FDG-PET in patients with colorectal liver metastases. For FDG-PET, the pooled sensitivity and specificity results were 88.0% and 96.1%, respectively, for hepatic disease and 91.5% and 95.4%, respectively, for extrahepatic disease. For the 6 articles that reported the highest scores on the index, the sensitivity and specificity of FDG-PET for hepatic metastatic disease were 79.9% and 92.3%, respectively, and 91.2% and 98.4%, respectively, for extrahepatic disease, respectively. For computed tomography, the pooled sensitivity and specificity results were 82.7% and 84.1%, respectively, for hepatic lesions and 60.9% and 91.1%, respectively, for

    AIM: To assess if a specific cytotoxic T cell response can be induced in patients with malignant liver tumors treated with radio-frequency ablation (RFA).METHODS: Six Patients with liver metastases of colorectal cancer and 6 with hepatocellular carcinoma (HCC)underwent RFA. Blood was sampled before, 4 and 8 wk after RFA. Test antigens were autologous liver and tumor lysate obtained from each patient by biopsy. Peripheral T cell activation was assessed by an interferon gamma (IFNγ) secretion assay and flow cytometry. T cells were double-stained for CD4/CD8 and IFNγ to detect cytotoxic T cells. The ratio of IFNγ positive and IFNγ negative T cells was determined as the stimulation index (SI). To assess cytolytic activity, T cells were co-incubated with human CaCo colorectal cancer and HepG2 HCC cells and release of cytosolic adenylate kinase was measured by a luciferase assay.RESULTS: Before RFA SI was 0.021 (±0.006) for CD4+and 0.022 (±0.004) for CD8+T cells against nonmalignant liver tissue and 0.018 (±0.005) for CD4+ and 0.021(±0.004) for CD8+ cells against autologous tumor tissue.Four weeks after RFA SI against tumor tissue increased to 0.109 (±0.005) for CD4+ and 0.11 (±0.012) for CD8+T cells against HCC, and to 0.115 (±0.031) for CD4+ and 0.15 (±0.02) for CD8+ cells for colorectal metastases (P <0.0001). No increased SI was observed with nonmalignant tumor tissue at all time points. Before RFA cytolytic activity against the respective cancer cells was low with 2.62 (±0.37) relative luminescence units (RLU), but rose more than 100 fold 4 and 8 wk after RFA. Spontaneous release was <2% of maximum release in all experiments.CONCLUSION: Patients with primary and secondary tumors of the liver show a significant tumor-specific cytotoxic T-cell stimulation with a dramatically increased tumor specific cytolytic activity of CD8+ T cells after RFA.

    Brain metastases occur in about 10% to 30% of breast cancer patients, which culminates in a poor prognosis. It is, therefore, critical to understand the molecular mechanisms underlying brain metastatic processes to identify relevant targets. We hypothesized that breast cancer cells must express brain-associated markers that would enable their invasion and survival in the brain microenvironment. We assessed a panel of brain-predominant markers and found an elevation of several neuronal markers (βIII-tubulin, Nestin, and AchE) in brain metastatic breast cancer cells. Among these neuronal predominant markers, in silico analysis revealed overexpression of βIII-tubulin (TUBB3) in breast cancer brain metastases (BCBM) and its expression was significantly associated with distant metastases. TUBB3 knockdown studies were conducted in breast cancer models (MDA-Br, GLIM2, and MDA-MB-468), which revealed significant reduction in their invasive capabilities. MDA-Br cells with suppressed TUBB3 also demonstrated loss of key signaling molecules such as β3 integrin, pFAK, and pSrc in vitro. Furthermore, TUBB3 knockdown in a brain metastatic breast cancer cell line compromised its metastatic ability in vivo, and significantly improved survival in a brain metastasis model. These results implicate a critical role of TUBB3 in conferring brain metastatic potential to breast cancer cells.

    Since liver cancer seriously threatens human health, it is very urgent to explore an effective method for diagnosing liver cancer early. In this study, we investigated the structure differences of IR spectra between neoplastic liver cells and normal liver cells. The major differences of absorption bands were observed between liver cancer cells and normal liver cells, the values of A2955/A2921, A1744/A1082, A1640/A1535, H1121/H1020 might be potentially useful factors for distinguishing liver cancer cells from normal liver cells. Curve fitting also provided some important information on structural differences between malignant and normal liver cancer cells. Furthermore, IR spectra combined with hierarchical cluster analysis could make a distinction between liver cancer cells and normal liver cells. The present results provided enough cell basis for diagnosis of liver cancer by FTIR spectroscopy, suggesting FTIR spectroscopy may be a potentially useful tool for liver cancer diagnosis.

    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.

    It is still not clear whether pulmonary resection may have a role in the multidisciplinary management of gastric cancer lung metastases. A systematic literature search was performed to identify all studies published between January 1998 and December 2014 about pulmonary resection of gastric cancer metastases. Ten studies published between 1998 and 2013 were retrieved, including a total of 44 patients. After gastrectomy, median disease-free interval was 35 months. Thirty-eight patients had single lung metastases, whereas six presented with more than one lesion. Median overall survival after lung resection was 45 months, and median disease-free survival was 9 months. Our analysis of the recent literature shows that lung metastasectomy for gastric cancer pulmonary metastases has been reported only in the setting of anecdotic cases or small series of highly selected patients. Lung metastasectomy has no role in the standard management of metastatic gastric patients and may actually be proposed only in individual highly selected cases.

    To determine if the histology of a breast malignancy influences the appearance of untreated osseous metastases on FDG PET/CT. This retrospective study was performed under IRB waiver. Our Hospital Information System was screened for breast cancer patients who presented with osseous metastases, who underwent FDG PET/CT prior to systemic therapy or radiotherapy from 2009 to 2012. Patients with invasive ductal carcinoma (IDC), invasive lobular carcinoma (ILC), or mixed ductal/lobular (MDL) histology were included. Patients with a history of other malignancies were excluded. PET/CT was evaluated, blinded to histology, to classify osseous metastases on a per-patient basis as sclerotic, lytic, mixed lytic/sclerotic, or occult on CT, and to record SUVmax for osseous metastases on PET. Following screening, 95 patients who met the inclusion criteria (74 IDC, 13 ILC, and 8 MDL) were included. ILC osseous metastases were more commonly sclerotic and demonstrated lower SUVmax than IDC metastases. In all IDC and MDL patients with osseous metastases, at least one was FDG-avid. For ILC, all patients with lytic or mixed osseous metastases demonstrated at least one FDG-avid metastasis; however, in only three of seven patients were sclerotic osseous metastases apparent on FDG PET. The histologic subtype of breast cancer affects the appearance of untreated osseous metastases on FDG PET/CT. In particular, non-FDG-avid sclerotic osseous metastases were more common in patients with ILC than in patients with IDC. Breast cancer histology should be considered when interpreting non-FDG-avid sclerotic osseous lesions on PET/CT, which may be more suspicious for metastases (rather than benign lesions) in patients with ILC.

    We describe the clinical and therapeutic course of a 51-year-old woman with HER-2+ breast cancer who developed leptomeningeal (LM) and spinal cord metastases after 8 years of stable disease on combination therapy with intravenous (IV) trastuzumab. Due to progressive CNS disease, intrathecal (IT) trastuzumab was introduced to enhance HER-2+ therapy into the CSF space. A combination HER-2+ targeted approach achieved clinical remission with stable disease in our patient 46 months after she was diagnosed with LM metastases. However, spinal cord C-1 metastasis was not fully controlled with IT trastuzumab, ultimately leading to the patient's respiratory compromise. In our patient, IT trastuzumab immunotherapy improved prognosis and was an effective strategy to manage HER-2+ LM disease. Given alone or alongside other anti-HER-2+ therapeutics with sufficient CNS penetration, IT trastuzumab could extend the lifespan of patients with leptomeningeal and CNS metastases.

    Distant metastases at primary diagnosis are a prognostic key factor in breast cancer patients and play a central role in therapeutic decisions. To detect them, chest X-ray, abdominal ultrasound, and bone scintigraphy are performed as standard of care in Germany and many centers worldwide. Although FDG PET detects metastatic disease with high accuracy, its diagnostic value in breast cancer still needs to be defined. The aim of this study was to compare the diagnostic performance of FDG PET with conventional imaging. Patients, methods: a retrospective analysis of 119 breast cancer patients who presented for staging was performed. Whole-body FDG-PET (n = 119) was compared with chest X-ray (n = 106) and bone scintigraphy (n = 95). Each imaging modality was independently assessed and classified for metastasis (negative, equivocal and positive). The results of abdominal ultrasound (n = 100) were classified as negative and positive according to written reports. Imaging results were compared with clinical follow-up including follow-up imaging procedures and histopathology. Results: FDG-PET detected distant metastases with a sensitivity of 87.3% and a specificity of 83.3%. In contrast, the sensitivity and specificity of combined conventional imaging procedures was 43.1% and 98.5%, respectively. Regarding so-called equivocal and positive results as positive, the sensitivity and specificity of FDG-PET was 93.1% and 76.6%, respectively, compared to 61.2% and 86.6% for conventional imaging. Regarding different locations of metastases the sensitivity of FDG PET was superior in the detection of pulmonary metastases and lymph node metastases of the mediastinum in comparison to chest X-ray, whereas the sensitivity of FDG PET in the detection of bone and liver metastases was comparable with bone scintigraphy and ultrasound of the abdomen. Conclusions: FDG-PET is more sensitive than conventional imaging procedures for detection of distant breast cancer metastases and should be

    Detection of bone metastases indicates poor prognosis for patients with prostate cancer. The immunotherapy with monoclonal antibody has been an important advance in the treatment of the cancer in the last years. Nimotuzumab is a humanized IgG1 monoclonal antibody directed against epidermal growth factor receptor that has been evaluated in solid tumors. The authors show images of 2 patients with bone metastases secondary to prostate cancer, "pre-cold therapy" with nimotuzumab. Immunoscintigraphic images were acquired 4 and 24 hours after the intravenous administration of 1110 MBq (30 mCi) of Tc-labeled nimotuzumab. Bone metastases expressing the receptor are visualized.

    Purpose: To evaluate technical feasibility and clinical outcome of computed tomography-guided high-dose-rate-brachytherapy (CT-HDRBT) ablation of metastases adjacent to the liver hilum. Materials and methods: Between November 2007 and May 2012, 32 consecutive patients with 34 metastases adjacent to the liver hilum (common bile duct or hepatic bifurcation ≤5 mm distance) were treated with CT-HDRBT. Treatment was performed by CT-guided applicator placement and high-dose-rate brachytherapy with an iridium-192 source. MRI follow-up was performed 6 weeks and every 3 months post intervention. The primary endpoint was local tumor control (LTC); secondary endpoints included time to progression (TTP) and overall survival (OS). Results: Patients were available for MRI evaluation for a mean follow-up time of 18.75 months (range: 3–56 months). Mean tumor diameter was 4.3 cm (range: 1.3–10.7 cm). One major complication was observed. Four (11.8%) local recurrences were observed after a local tumor control of 5, 8, 9 and 10 months, respectively. Twenty-two patients (68.75%) experienced a systemic tumor progression during the follow up period. Mean TTP was 12.9 months (range: 2–56 months). Nine patients died during the follow-up period. Median OS was 20.24 months. Conclusion: Minimally invasive CT-HDRBT is a safe and effective option also for unresectable liver metastases adjacent to the liver hilum that would have been untreatable by thermal ablation.

    Purpose: To evaluate the feasibility of high-dose stereotactic body radiation therapy (SBRT) in the treatment of unresectable liver metastases. Methods and Materials: Patients with 1 to 3 liver metastases, with maximum individual tumor diameters less than 6 cm and a Karnofsky Performance Status of at least 70, were enrolled and treated by SBRT on a phase 2 clinical trial. Dose prescription was 75 Gy on 3 consecutive days. SBRT was delivered using the volumetric modulated arc therapy by RapidArc (Varian, Palo Alto, CA) technique. The primary end-point was in-field local control. Secondary end-points were toxicity and survival. Results: Between February 2010 and September 2011, a total of 61 patients with 76 lesions were treated. Among the patients, 21 (34.3%) had stable extrahepatic disease at study entry. The most frequent primary sites were colorectal (45.9%) and breast (18%). Of the patients, 78.7% had 1 lesion, 18.0% had 2 lesions, and 3.3% had 3 lesions. After a median of 12 months (range, 2-26 months), the in-field local response rate was 94%. The median overall survival rate was 19 months, and actuarial survival at 12 months was 83.5%. None of the patients experienced grade 3 or higher acute toxicity. No radiation-induced liver disease was detected. One patient experienced G3 late toxicity at 6 months, resulting from chest wall pain. Conclusions: SBRT for unresectable liver metastases can be considered an effective, safe, and noninvasive therapeutic option, with excellent rates of local control and a low treatment-related toxicity.

    Full Text Available Background/Aim. Detection of metastatic bone disease by skeletal scintigraphy is a classical application of nuclear medicine in cancer patients. Detection of bone metastases in patients with lung cancer is necessary for an appropriate treatment modality. The aim of this study was to report the frequency and imaging characteristics of bone metastases detected by bone scintigraphy (BS using technetium-99m phosphonates in patients with lung cancer. Methods. We retrospectively analyzed a total of one hundred patients (78 males and 22 females, mean age of 63.3 years, with the diagnosis of lung cancer, who underwent BS during a three-year period (2003−2005. Scintiscans were classified as positive, negative and suspicious with regard to the presence of bone metastases. Results. The incidence of positive, negative and suspicious findings were 57%. 32% and 11%, respectively. Out of 57 patients with bone metastases, 51 had multiple asymmetric foci of increased tracer activity localized in the ribs, spine, extremities, pelvis, sternum, scapula and skull in 72%, 54%, 49%, 37%, 12%, 9% and 5% of scans, respectively. BS revealed solitary metastases in 6 of the patients. The lesions were located in the lower limbs in three patients and in the upper limbs, pelvis and sternum in the remaining three patients. Conclusion. Bone scintigraphy plays a significant role in staging and selecting of patients for curative lung surgery. Due to the fact that metastatic involvment of the extremities was frequently shown, our study suggests that systematic inclusion of the limbs in BS acquisition should be obligatory.

    Full Text Available Abstract Background Several studies have identified rare genetic variations responsible for many cases of familial breast cancer but their contribution to total breast cancer incidence is relatively small. More common genetic variations with low penetrance have been postulated to account for a higher proportion of the population risk of breast cancer. Methods and Results In an effort to identify genes that influence non-familial breast cancer risk, we tested over 25,000 single nucleotide polymorphisms (SNPs located within approximately 14,000 genes in a large-scale case-control study in 254 German women with breast cancer and 268 age-matched women without malignant disease. We identified a marker on chromosome 14q24.3-q31.1 that was marginally associated with breast cancer status (OR = 1.5, P = 0.07. Genotypes for this SNP were also significantly associated with indicators of breast cancer severity, including presence of lymph node metastases (P = 0.006 and earlier age of onset (P = 0.01. The association with breast cancer status was replicated in two independent samples (OR = 1.35, P = 0.05. High-density association fine mapping showed that the association spanned about 80 kb of the zinc-finger gene DPF3 (also known as CERD4. One SNP in intron 1 was found to be more strongly associated with breast cancer status in all three sample collections (OR = 1.6, P = 0.003 as well as with increased lymph node metastases (P = 0.01 and tumor size (P = 0.01. Conclusion Polymorphisms in the 5' region of DPF3 were associated with increased risk of breast cancer development, lymph node metastases, age of onset, and tumor size in women of European ancestry. This large-scale association study suggests that genetic variation in DPF3 contributes to breast cancer susceptibility and severity.

    ABSTRACT Therapies for liver cancer particularly those including radiation are still inadequate. Inhibiting the stress response machinery is an appealing anti-cancer and radiosensitizing therapeutic strategy. Heat-shock-protein-90 (HSP90) is a molecular chaperone that is a prominent effector of the stress response machinery and is overexpressed in liver cancer cells. HSP90 client proteins include critical components of pathways implicated in liver cancer cell survival and radioresistance. The effects of a novel non-geldanamycin HSP90 inhibitor, ganetespib, combined with radiation were examined on 3 liver cancer cell lines, Hep3b, HepG2 and HUH7, using in vitro assays for clonogenic survival, apoptosis, cell cycle distribution, γH2AX foci kinetics and client protein expression in pathways important for liver cancer survival and radioresistance. We then evaluated tumor growth delay and effects of the combined ganetespib-radiation treatment on tumor cell proliferation in a HepG2 hind-flank tumor graft model. Nanomolar levels of ganetespib alone exhibited liver cancer cell anti-cancer activity in vitro as shown by decreased clonogenic survival that was associated with increased apoptotic cell death, prominent G2-M arrest and marked changes in PI3K/AKT/mTOR and RAS/MAPK client protein activity. Ganetespib caused a supra-additive radiosensitization in all liver cancer cell lines at low nanomolar doses with enhancement ratios between 1.33–1.78. These results were confirmed in vivo, where the ganetespib-radiation combination therapy produced supra-additive tumor growth delay compared with either therapy by itself in HepG2 tumor grafts. Our data suggest that combined ganetespib-radiation therapy exhibits promising activity against liver cancer cells, which should be investigated in clinical studies. PMID:26980196

    Primary hepatic leiomyosarcoma is a particularly rare tumor with a poor prognosis.Curative resection is currently the only effective treatment,and the efficacy of chemotherapy is unclear.This represents the first case report of a patient with primary hepatic leiomyosarcoma co-existing with metastatic liver carcinoma.We present a 59-year-old man who was diagnosed preoperatively with rectal cancer with multiple liver metastases.He underwent a curative hepatectomy after a series of chemotherapy regimens with modified FOLFOX6 consisting of 5-fluorouracil,leucovorin and oxaliplatin plus bevacizumab,FOLFIRI consisting of 5-fluorouracil,leucovorin and irinotecan plus bevacizumab,and irinotecan plus cetuximab.One of the liver tumors showed a different response to chemotherapy and was diagnosed as a leiomyosarcoma following histopathological examination.This case suggests that irinotecan has the potential to inhibit the growth of hepatic leiomyosarcomas.The possibility of comorbid different histological types of tumors should be suspected when considering the treatment of multiple liver tumors.

    Full Text Available Abstract Background Foetal antigen 2 (FA-2, first isolated in the amniotic fluid, was shown to be the circulating form of the aminopropeptide of the alpha 1 chain of procollagen type I. Serum concentrations of FA-2 appeared to be elevated in a number of disorders of bone metabolism. This paper is the first report of its role as a marker of bone metabolism in metastatic breast cancer. Methods Serum FA-2 concentrations were measured by radioimmunoassay in 153 women with different stages of breast cancer and in 34 normal controls. Results Serum FA-2 was significantly elevated in women with bony metastases (p Conclusions FA-2 is a promising blood marker of bone metabolism. Further studies to delineate its role in the diagnosis and management of bony metastases from breast cancer are required.

    Metastasized lung and liver cancers cause over 2 million deaths annually, and are amongst the top killer cancers worldwide. Morinda citrifolia (Noni) leaves are traditionally consumed as vegetables in the tropics. The macro and micro effects of M. citrifolia (Noni) leaves on metastasized lung cancer development in vitro and in vivo were compared with the FDA-approved anti-cancer drug Erlotinib. The extract inhibited the proliferation and induced apoptosis in A549 cells (IC50 = 23.47 μg/mL) and mouse Lewis (LL2) lung carcinoma cells (IC50 = 5.50 μg/mL) in vitro, arrested cancer cell cycle at G0/G1 phases and significantly increased caspase-3/-8 without changing caspase-9 levels. The extract showed no toxicity on normal MRC5 lung cells. Non-small-cell lung cancer (NSCLC) A549-induced BALB/c mice were fed with 150 and 300 mg/kg M. citrifolia leaf extract and compared with Erlotinib (50 mg/kg body weight) for 21 days. It significantly increased the pro-apoptotic TRP53 genes, downregulated the pro-tumourigenesis genes (BIRC5, JAK2/STAT3/STAT5A) in the mice tumours, significantly increased the anti-inflammatory IL4, IL10 and NR3C1 expression in the metastasized lung and hepatic cancer tissues and enhanced the NFE2L2-dependent antioxidant responses against oxidative injuries. The extract elevated serum neutrophils and reduced the red blood cells, haemoglobin, corpuscular volume and cell haemoglobin concentration in the lung cancer-induced mammal. It suppressed inflammation and oedema, and upregulated the endogenous antioxidant responses and apoptotic genes to suppress the cancer. The 300 mg/kg extract was more effective than the 50 mg/kg Erlotinib for most of the parameters measured.

    Metastasis is a process consisting of cells spreading from the primary site of the cancer to distant parts of the body. Our understanding of this spread is limited and molecular mechanisms causing particular characteristics of metastasis are still unknown. There is some evidence that primary renal cell carcinoma (RCC) and metastases of RCC exhibit molecular differences that may effect on the biological characteristics of the tumor. Some authors have detected differences in clear cell and nonclear cell component between these 2 groups of tumors. Investigators have also determined that primary RCC and metastases of RCC diverge in their range of renal-specific markers and other protein expression, gene expression pattern, and microRNA expression. There are also certain proteins that are variously expressed in primary RCCs and their metastases and have effect on clinical outcome, e.g., endothelin receptor type B, phos-S6, and CD44. However, further studies are needed on large cohorts of patients to identify differences representing promising targets for prognostic purposes predicting disease-free survival and the metastatic burden of a patient as well as their suitability as potential therapeutic targets. To sum up, in this review we have attempted to summarize studies connected with differences between primary RCC and its metastases and their influence on the biological characteristics of renal cancer.

    Differentiation between liver metastases and local fat desposition may be difficult when using CT; the value of MRI was therefore investigated in 18 patients with metastases and ten patients with fat deposits. CT shows both lesions as similar hypodense areas. MRI, however, produces different appearances: T1- and 2-weighted images show marked differences in the signal arising from metastases, whereas local fat collections in both sequences differ little in their signal from normal liver. Quantitative MRI signal intensity of the two types of lesion were also different. Where the differentiation by CT may be difficult, it may be made with certainty by means of MRI. (orig.).

    Claudin-2 enhances breast cancer liver metastasis and promotes the development of colorectal cancers. The objective of our current study is to define the regulatory mechanisms controlling Claudin-2 expression in breast cancer cells. We evaluated the effect of several Src Family Kinase (SFK) inhibitors or knockdown of individual SFK members on Claudin-2 expression in breast cancer cells. We also assessed the potential effects of pan-SFK and SFK-selective inhibitors on the formation of breast cancer liver metastases. This study reveals that pan inhibition of SFK signaling pathways significantly elevated Claudin-2 expression levels in breast cancer cells. In addition, our data demonstrate that pan-SFK inhibitors can enhance breast cancer metastasis to the liver. Knockdown of individual SFK members reveals that loss of Yes or Fyn induces Claudin-2 expression; whereas, diminished Lyn levels impairs Claudin-2 expression in breast cancer cells. The Lyn-selective kinase inhibitor, Bafetinib (INNO-406), acts to reduce Claudin-2 expression and suppress breast cancer liver metastasis. Our findings may have major clinical implications and advise against the treatment of breast cancer patients with broad-acting SFK inhibitors and support the use of Lyn-specific inhibitors.

    The intra-arterial administration of {sup 90}Y microspheres is a new palliative treatment option for unresectable liver metastases. The aim of this study was to quantitatively assess changes in FDG uptake and tumour size following {sup 90}Y microsphere treatment (SIR-Spheres) using {sup 18}F-fluorodeoxyglucose (FDG) PET/CT imaging. Five patients with unresectable liver metastases who had failed multiple prior chemotherapy regimens received seven {sup 90}Y microsphere treatments to a single liver lobe. All patients underwent a baseline PET/CT scan prior to treatment, as well as up to four follow-up PET/CT scans. The tumour area of 30 liver metastases was measured on CT and the FDG uptake was semiquantitatively assessed by calculation of standardised uptake values (SUVs). A total of 18 FDG-PET/CT scans were performed. The SUVs in the 30 treated liver metastases decreased from 6.5{+-}2.3 at baseline to 4.2{+-}1.8 after the first follow-up PET/CT scan (p=0.001). In contrast, the SUVs of untreated metastases increased slightly from 7.2{+-}2.3 to 8.0{+-}0.8. There was no difference in FDG uptake in treated versus untreated normal liver tissue. Using a previously defined threshold of 20% decrease in SUV from baseline to determine response, 20 out of 30 liver metastases were considered to have responded at the first follow-up PET/CT scan approximately 1 month after treatment. In these metastases, the SUV decreased by 47{+-}12%, compared with a slight increase by 5.9{+-}19% in ten non-responding metastases (p=0.0001). The changes in tumour size did not correlate with changes in FDG uptake. On the first follow-up PET/CT scan, the tumour area on CT increased by 3.1{+-}57% in treated metastases compared with 23.3{+-}32% in untreated metastases. A wide range of post-treatment changes of target lesions was observed on CT, including an increase in the size of hypodense lesions, necrotic features and complete resolution of CT abnormalities.

    Purpose: To elucidate survival times and identify potential prognostic factors in patients with triple-negative (TN) phenotype who harbored brain metastases arising from breast cancer and who underwent stereotactic radiosurgery (SRS). Methods and Materials: A total of 103 breast cancer patients with brain metastases were treated with SRS and then studied retrospectively. Twenty-four patients (23.3%) were TN. Survival times were estimated using the Kaplan-Meier method, with a log-rank test computing the survival time difference between groups. Univariate and multivariate analyses to predict potential prognostic factors were performed using a Cox proportional hazard regression model. Results: The presence of TN phenotype was associated with worse survival times, including overall survival after the diagnosis of primary breast cancer (43 months vs. 82 months), neurologic survival after the diagnosis of intracranial metastases, and radiosurgical survival after SRS, with median survival times being 13 months vs. 25 months and 6 months vs. 16 months, respectively (p < 0.002 in all three comparisons). On multivariate analysis, radiosurgical survival benefit was associated with non-TN status and lower recursive partitioning analysis class at the initial SRS. Conclusion: The TN phenotype represents a significant adverse prognostic factor with respect to overall survival, neurologic survival, and radiosurgical survival in breast cancer patients with intracranial metastasis. Recursive partitioning analysis class also served as an important and independent prognostic factor.

    Peptide receptor radionuclide therapy with Lu or Y is promising with successful results in somatostatin receptor-positive tumors. In all radiation therapies, knowledge of the radiation dose received by the target, and other organs in the body is essential to evaluate the risks and benefits of any procedure. We report a case of liver metastases from a rectal neuroendocrine tumor, which was treated with Y DOTANOC. Posttreatment whole-body planar images were acquired through Bremsstrahlung radiations of Y on a γ-camera, and thoracolumbar PET/CT images were acquired on PET.

    Laparoscopic liver surgery has gained widespread acceptance and nowadays it is suggested even for malignant disease. Although the benefits on short-term outcomes have been proven, data on oncological safety are still lacking. The aim of this study is to assess oncologic results after ultrasound-guided laparoscopic liver resection (LLR) or open liver resection (OLR) for colorectal metastases. 37 consecutive patients undergoing LLR between 01/2004 and 03/2014 were matched at a ratio of 1:1 with 37 OLR. Matching criteria were male sex, number and diameter of liver metastases, segment location, synchronous presentation, site and stage of primary tumor, positive lymph nodes of the primary, and concomitant extrahepatic disease. Demographic characteristics were similar among groups. Parenchymal transection time was longer in the LLR group (68 ± 38.2 SD vs 40 ± 33.7 SD, p = 0.01). Mortality was nil in LLR and OLR. Overall morbidity was significantly lower in LLR (13.5 vs 37.8%, p = 0.02), although severe complications were similar among the two groups. Patients undergoing LLR were discharged earlier (5 ± 2.3 SD vs 8 ± 6.6 SD days, p resection was recorded in four LLR and three OLR (p = 1). Overall recurrences were similar among groups. Eight patients with hepatic or extrahepatic recurrence among LLR underwent surgery vs four of OLR (p = 0.03). After a median follow-up of 35.7 months in LLR and 47.9 months in OLR, 3-year overall survival was 91.8% LLR and 74.8% OLR (p = 0.14). 3-year disease-free survival was 69.1% LLR and 65.9% OLR (p = 0.53). Multivariate analysis showed that postoperative complications [HR 3.42 (95% CI 1.32-8.89)] and multiple metastases [HR 3.84 (95% CI 1.34-10.83)] were independent predictors of worse survival (p = 0.01). Ultrasound-LLR for colorectal hepatic metastases is safe, ensuring oncologic outcomes comparable to OLR.

    Bone metastases are a major problem in the clinical management of patients with prostate cancer. Despite the use of analgesic for the relief of such pain, the outcomes are not often satisfactory. Strontium-89 (89Sr) is a pure beta-emitting radioisotope to be avidly concentrated in the areas of high osteoblastic activity. The aim of this study was to evaluate the efficacy of 89Sr in the therapy for bone metastases of prostate carcinoma. 116 patients received intravenous injection of 89Sr at the dose of 3mCi (111MBq). All patients underwent physical examination and Karnofsky's Performance Score (KPS) evaluation before and after administration; the analgesic effects were evaluated by scores of pain. The complete response (CR) was defined as scores of pain > 75%; no response (NR) was defined as scores of pain bone metastases were screened by CT, MRI and 99mTc-MDP bone scintigraphy according to the standards of WHO. After the treatment with 89Sr, the total response rate was 80.2%. In the 116 cases, 21 cases (18.1%) displayed complete response and 72 cases (62.1%) displayed partial response, but 23 cases (19.2%) showed no response. The mean score on Karnfsky's performance status (KPS) was 20.0% higher. About 1/3 cases exhibited an obvious decrease in the number of metastases, and some foci disappeared. Thirteen cases (12%) showed a greater decrease in prostate-specific antigen (PSA) value. 89Sr chloride is an effective and safe therapy of the bone metastases from prostate cancer.

    Full Text Available Context: Bone marrow (BM metastases are an integral part of tumor dissemination in many malignancies. Prostate carcinoma, which has high tendency to metastasize to bone, shown to have affinity for endosteal niche as well as tendency to compete with hematopoietic cells to home in BM. This marrow dissemination can be confidently proved by histopathological examination of BM. Aims: In this study, we are trying to detect the presence of metastases and micrometastases in BM of prostate carcinoma patients with the help of immunohistochemical markers prostate-specific antigen (PSA and prostate-specific acid phosphatase and correlate the findings with American Joint Committee on Cancer Tumor, Node and Metastasis 7 th (2010 classification, serum PSA, and biopsy Gleason′s score. Materials and Methods: We performed BM examination and hematological workup of 11 known prostate carcinoma patients including metastatic cases also, during our study period of 1 year. The BM biopsy sections and clot sections were used to carry out immunohistochemistry. The data were analyzed by using SPSS (Statistical Package for Social Sciences version 15.0 statistical analysis software. Results: We found that two patients were positive for metastases in BM out of the 11. Both of these patients already had metastases to other site with very high serum PSA levels. Anemia was common hematological alteration in both of them and one of them showed increased osteoblasts in the aspirate film. Conclusion: Taking into account our small sample size and short study duration, we conclude that further large sized future studies with long-term follow-up in to this BM dissemination by prostate cancer cells could open new horizons to understand the biology of metastasis of this common malignancy and also provide more effective therapeutic options as well as prognostic implications in these patients.

    Cellular proliferation depends on refilling the tricarboxylic acid (TCA) cycle to support biomass production (anaplerosis). The two major anaplerotic pathways in cells are pyruvate conversion to oxaloacetate via pyruvate carboxylase (PC) and glutamine conversion to α-ketoglutarate. Cancers often show an organ-specific reliance on either pathway. However, it remains unknown whether they adapt their mode of anaplerosis when metastasizing to a distant organ. We measured PC-dependent anaplerosis ...

    Full Text Available Aim.The purpose of this study was to examine the outcome of patients with skeletal metastases from well-differentiated thyroid carcinoma and analyse the effect of variables that influence the prognosis of this disease. Method. We retrospectively reviewed 352 patients treated and followed-up at the Charlotte Maxeke Johannesburg Academic Hospital’s thyroid cancer clinic from 1982 - 1999. Findings. Skeletal metastases were diagnosed in 24 (6.8%, 17 at presentation to the thyroid clinic, and 7 at follow-up. Patients’ ages ranged from 30 - 77 years (mean 53.9 years and the female:male ratio was 3.8:1. Based on the original pathology reports from resected tumours, 9 were papillary and 15 were follicular cancers. Twenty-three of the 24 patients underwent thyroid surgery as the initial management – total thyroidectomy in 18, subtotal thyroidectomy in 3, and lobectomy plus neck dissection in one. The diagnosis of thyroid cancer was based on lobectomy in a single subject. Radioactive iodine (RAI was used as part of the original treatment; external radiation therapy (XRT was mainly used to alleviate severe symptoms. Twenty-one patients (87.5% were treated with RAI; 11 (45.8% received radiotherapy. Seven patients died – 4 from neurological disease directly associated with bone metastases. Of the 17 surviving patients, 2 appeared to be disease-free, 8 were asymptomatic despite overt bony disease, and 7 had persistent symptoms which much improved in 5. Bone metastases were uncommon, and follicular cancer predominated in this survey. Conclusion. RAI therapy improves quality of life in most patients. There is a place for XRT.

    Liver cancer is an extraordinarily heterogeneous malignant disease among the tumors that have so far been identified. Hepatocellular carcinoma (HCC) arises most frequently in the setting of chronic liver inflammation and fibrosis, and takes a variety of course in individual patients to process to tumor. The risk factors such as HBV and/or HCV infections, aflatoxin infection, abuse alcohol intake, metabolic syndrome, obesity and diabetes are closely related to the environmental and genetic susceptibilities to HCC. The consequent resulting genomic instability, molecular and signal transduction network disorders and microenvironmental discrepancies are characterized by the extraordinary heterogeneity of liver cancer. The histology-based definition of the morphological heterogeneity of liver cancer has been modified and refined to treat patients with targeted therapies, but this still cannot solve all the problems. Lack of consistent outcome for anticancer agents and conventional therapies in liver cancer treatment calls for assessing the benefits of new molecularly targeted drugs and combined therapy, under the heterogeneity condition of tumor. The present review article will provide the complex mechanism and phenotype of liver cancer heterogeneity, and help us to execute precision medicine in a really personalized manner.

    Full Text Available Abstract Background The adrenal gland is one of the common sites of metastasis from primary lung cancer. Adrenal metastases are usually unilateral however bilateral adrenal metastases are seen in 10% of all lung cancer patients; of these 2–3% occurs at the initial presentation of non-small cell lung cancer. Secondary tumors can disrupt the structure and function of the adrenal. This can lead to adrenal hemorrhage, which constitutes a life threatening hazard for the patient. Case presentation A 59-year-old male presented with persisting abdominal pain. His initial work-up revealed significant anemia, an invasive process in the right upper lobe of the lung and large masses of heterogeneous texture, with hemorrhagic and necrotic elements in both adrenal glands. A biopsy confirmed it to be a large-cell carcinoma of the lungs. The patient developed severe leukocytosis akin to the paraneoplastic syndrome and died suddenly five days after the administration of chemotherapy. Conclusion Intratumoral hemorrhage is a rare but life threatening complication of adrenal metastases and should be treated as soon as it has been diagnosed. If adrenalectomy is not feasible, combination chemotherapy should be applied as in metastatic disease. For choosing the appropriate chemotherapeutic regimen it is important to accurately achieve the diagnosis.

    Detection and segmentation of ovarian cancer metastases have great clinical impacts on women's health. However, the random distribution and weak boundaries of metastases significantly complicate this task. This paper presents a variational framework that combines region competition based level set propagation and image matching flow computation to jointly detect and segment metastases. Image matching flow not only detects metastases, but also creates shape priors to reduce over-segmentation. Accordingly, accurate segmentation helps to improve the detection accuracy by separating flow computation in metastasis and non-metastasis regions. Since all components in the image processing pipeline benefit from each other, our joint framework can achieve accurate metastasis detection and segmentation. Validation on 50 patient datasets demonstrated that our joint approach was superior to a sequential method with sensitivity 89.2% vs. 81.4% (Fisher exact test p = 0.046) and false positive per patient 1.04 vs. 2.04. The Dice coefficient of metastasis segmentation was 92 +/- 5.2% vs. 72 +/- 8% (paired t-test p = 0.022), and the average surface distance was 1.9 +/- 1.5mm vs. 4.5 +/- 2.2mm (paired t-test p = 0.004).

    Results. Some response was seen in all 14 patients. Carcinoid syndrome improved or resolved in 10/10 instances. 24-hour urinary 5-HIAA or serum chromogranin A levels fell dramatically in 5/7 patients following SIRT. Serial CT scans revealed partial response or stable disease in all 14 patients. Repeat treatment in three patients experiencing progression was associated with a further response. Median survival after SIRT is 25 months with 6 patients being alive (and 3 patients still asymptomatic, at 19, 22, 23, 23, 58, and 60 months. Conclusions. SIRT is an effective and well-tolerated treatment for non-resectable NET liver metastases capable of both alleviating the carcinoid syndrome and achieving significant tumour regression. Repeat treatment is an option and liver resection after downstaging may also become possible.

  3. Is there a genetic signature for liver metastasis in colorectal cancer?

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Even though liver metastasis accounts for the vast majority of cancer deaths in patients with colorectal cancer (CRC), fundamental questions about the molecular and cellular mechanisms of liver metastasis still remain unanswered. Determination of gene expression profiles by microarray technology has improved our knowledge of CRC molecular pathways. However, defined gene signatures are highly variable among studies. Expression profiles and molecular markers have been specifically linked to liver metastases mechanistic paths in CRC. However, to date, none of the identified signatures or molecular markers has been successfully validated as a diagnostic or prognostic tool applicable to routine clinical practice. To obtain a genetic signature for liver metastasis in CRC, measures to improve reproducibility, to increase consistency, and to validate results need to be implemented. Alternatives to expression profiling with microarray technology are continuing to be used. In the recent past, many genes codifying for proteins that are directly or indirectly involved in adhesion, invasion, angiogenesis, survival and cell growth have been linked to mechanisms of liver metastases in CRC.

    Purpose: To investigate measurement accuracy in terms of precision and inter-rater variability in the simultaneous volumetric assessment of lung, liver and lymph node metastasis size change over time in comparison to RECIST 1.1. Materials and Methods: Three independent readers evaluated multislice CT data from clinical follow-up studies (chest/abdomen) in 50 patients with metastases. A total of 117 lung, 77 liver and 97 lymph node metastases were assessed manually (RECIST 1.1) and by volumetry with semi-automated software. The quality of segmentation and need for manual adjustments were recorded. Volumes were converted to effective diameters to allow comparison to RECIST. For statistical assessment of precision and interobserver agreement, the Wilcoxon-signed rank test and Bland-Altman plots were utilized. Results: The quality of segmentation after manual correction was acceptable to excellent in 95 % of lesions and manual corrections were applied in 21 - 36 % of all lesions, most predominantly in lymph nodes. Mean precision was 2.6 - 6.3 % (manual) with 0.2 - 1.5 % (effective) relative measurement deviation (p <.001). Inter-reader median variation coefficients ranged from 9.4 - 12.8 % (manual) and 2.9 - 8.2 % (volumetric) for different lesion types (p <.001). The limits of agreement were {+-} 9.8 to {+-} 11.2 % for volumetric assessment. Conclusion: Superior precision and inter-rater variability of volumetric over manual measurement of lesion change over time was demonstrated in a whole body setting. (orig.)

    Full Text Available CONTEXT AND OBJECTIVE: Around 16% to 20% of women with breast cancer have advanced, metastasized breast cancer. At this stage, the disease is treatable, but not curable. The objective here was to assess the effectiveness of lapatinib for treating patients with advanced or metastasized breast cancer. DESIGN AND SETTING: Systematic review of the literature, developed at Centro Paulista de Economia da Saúde (CPES, Universidade Federal de São Paulo (Unifesp. METHOD: Systematic review with searches in virtual databases (PubMed, Lilacs [Literatura Latino-Americana e do Caribe em Ciências da Saúde], Cochrane Library, Scirus and Web of Science and manual search. RESULTS: Only one clinical trial that met the selection criteria was found. This study showed that lapatinib in association with capecitabine reduced the risk of cancer progression by 51% (95% confidence interval, CI: 0.34-0.71; P < 0.001, compared with capecitabine alone, without any increase in severe adverse effects. CONCLUSION: The combination of lapatinib plus capecitabine was more effective than capecitabine alone for reducing the risk of cancer progression. Further randomized clinical trials need to be carried out with the aim of assessing the effectiveness of lapatinib as monotherapy or in association for first-line or second-line treatment of advanced breast cancer.

    In recent years, immunotherapy has gained renewed interest as an alternative therapeutic approach for solid tumors. Its premise is based on harnessing the power of the host immune system to destroy tumor cells. Development of immune-mediated therapies, such as vaccines, adoptive transfer of autologous immune cells, and stimulation of host immunity by targeting tumor-evasive mechanisms have advanced cancer immunotherapy. In addition, studies on innate immunity and mechanisms of immune evasion have enhanced our understanding on the immunology of liver cancer. Preclinical and clinical studies with immune-mediated therapies have shown potential benefits in patients with liver cancer. In this review, we summarize current knowledge and recent developments in tumor immunology by focusing on two main primary liver cancers: hepatocellular carcinoma and cholangiocarcinoma.

    2014-06-01

    The management of synchronous presentation of colorectal cancer and liver metastases has long been a topic of debate and discussion for surgeons due to the unique dilemma of balancing operative timing along with treatment strategy. Operative strategies for resection include staged resection with colon first approach, "reverse" staged resection with liver metastases resected first, and one-stage, or simultaneous, resection of both the primary tumor and liver metastases approach. These operative strategies can be further augmented with perioperative chemotherapy and other novel approaches that may improve resectability and patient survival. The decision on operative timing and approach, however, remains largely dependent on the surgeon's determination of disease resectability, patient fitness, and the need for neoadjuvant chemotherapy.

    The development of novel therapies for breast cancer bone metastasis is a major unmet medical need. Toward that end, we have constructed an oncolytic adenovirus, Ad.dcn, and a nonreplicating adenovirus, Ad(E1-).dcn, both containing the human decorin gene. Our in vitro studies showed that Ad.dcn produced high levels of viral replication and the decorin protein in the breast tumor cells. Ad(E1-).dcn-mediated decorin expression in MDA-MB-231 cells downregulated the expression of Met, β-catenin, and vascular endothelial growth factor A, all of which are recognized decorin targets and play pivotal roles in the progression of breast tumor growth and metastasis. Adenoviral-mediated decorin expression inhibited cell migration and induced mitochondrial autophagy in MDA-MB-231 cells. Mice bearing MDA-MB-231-luc skeletal metastases were systemically administered with the viral vectors, and skeletal tumor growth was monitored over time. The results of bioluminescence imaging and X-ray radiography indicated that Ad.dcn and Ad(E1-).dcn significantly inhibited the progression of bone metastases. At the terminal time point, histomorphometric analysis, micro-computed tomography, and bone destruction biomarkers showed that Ad.dcn and Ad(E1-).dcn reduced tumor burden and inhibited bone destruction. A nonreplicating adenovirus Ad(E1-).luc expressing the luciferase 2 gene had no significant effect on inhibiting bone metastases, and in several assays, Ad.dcn and Ad(E1-).dcn were better than Ad.luc, a replicating virus expressing the luciferase 2 gene. Our data suggest that adenoviral replication coupled with decorin expression could produce effective antitumor responses in a MDA-MB-231 bone metastasis model of breast cancer. Thus, Ad.dcn could potentially be developed as a candidate gene therapy vector for treating breast cancer bone metastases.

    The objective of this project was to systematically determine the prevalence and consequences of pulmonary fibrosis in youth with thyroid carcinoma and lung metastases from Belarus who were treated with radioiodine ({sup 131}I). A total of 69 patients treated for juvenile thyroid carcinoma and lung metastasis with {sup 131}I were assessed. A group of 29 patients without lung metastases and prior {sup 131}I treatment served as controls. The assessments included a CT scan of the lungs, extensive pulmonary function testing and an incremental cycle test to volitional fatigue with measurements of oxygen uptake (V. O{sub 2}), oxygen saturation and alveolar-arterial difference in oxygen partial pressure ({delta}aaO{sub 2}). Five patients with lung metastases showed advanced pulmonary fibrosis on CT scans and also had poorer lung functions compared with the 62 patients with none or minor signs of fibrosis and the 29 controls. Furthermore, these five patients showed lower peak V.O{sub 2}, lower oxygen saturation at peak exercise and higher exercise {delta}aaO{sub 2}. They were younger at the time of cancer diagnosis and had received chemotherapy more frequently than youth with pulmonary metastases who did not develop fibrosis. One of the five patients subsequently died from pulmonary fibrosis. Following the Chernobyl catastrophe, about 7% of children treated with radioiodine for thyroid carcinoma and lung metastases displayed pulmonary fibrosis which was associated with functional impairments. Based on the characteristics of affected individuals, the number of radioiodine courses may have to be limited, especially in young children, and chemotherapy should be avoided. (orig.)

    A patient presented with local pain and voiding difficulties due to a bulky prostatic cancer and diffuse metastatic lesions throughout the pars spongiosa of the urethra. This rare event prompted us to review the literature. Lacking a specific palliative therapy, we developed a technique of intraurethral brachytherapy. With this treatment, we were able to reach a life-lasting palliation. (orig.)

    The aim of this prospective study was to compare the diagnostic performance of 64-row MDCT and gadoxetic-acid-enhanced MRI at 3.0 T in patients with colorectal liver metastases in correlation with histopathological findings. Lesions detected at MDCT and MRI were interpreted by three blinded readers and compared with histopathological workup as the term of reference. Two subgroups of lesions were additionally evaluated: (1) metastases smaller than 10 mm and (2) lesions in patients with and without steatosis of the liver, assessed histopathologically. Surgery and histopathological workup revealed 81 colorectal liver metastases in 35 patients and diffuse metastatic involvement in 3 patients. In a lesion-by-lesion analysis, significant sensitivity differences could only be found for reader 1 (P = 0.035) and reader 3 (P = 0.003). For segment-based evaluation, MRI was more sensitive only for reader 3 (P = 0.012). The number of false-positive results ranged from 3 to 12 for MDCT and 8 to 11 for MRI evaluation. In the group of small lesions, the sensitivity differed significantly between both methods (P = 0.003). In patients with hepatic steatosis, MRI showed a trend toward better performance than MDCT, but without statistical performance. The 3.0-T MRI with liver-specific contrast agents is the preferred investigation in the preoperative setting, especially for the assessment of small colorectal liver metastases. (orig.)

    Personalized medicine uses genomic information for selecting therapy in patients with metastatic cancer. An issue is the optimal tissue source (primary tumor or metastasis) for testing. We compared the DNA copy number and mutational profiles of primary breast cancers and paired metastases from 23 patients using whole-genome array-comparative genomic hybridization and next-generation sequencing of 365 "cancer-associated" genes. Primary tumors and metastases harbored copy number alterations (CNAs) and mutations common in breast cancer and showed concordant profiles. The global concordance regarding CNAs was shown by clustering and correlation matrix, which showed that each metastasis correlated more strongly with its paired tumor than with other samples. Genes with recurrent amplifications in breast cancer showed 100% (ERBB2, FGFR1), 96% (CCND1), and 88% (MYC) concordance for the amplified/non-amplified status. Among all samples, 499 mutations were identified, including 39 recurrent (AKT1, ERBB2, PIK3CA, TP53) and 460 non-recurrent variants. The tumors/metastases concordance of variants was 75%, higher for recurrent (92%) than for non-recurrent (73%) variants. Further mutational discordance came from very different variant allele frequencies for some variants. We showed that the chosen targeted therapy in two clinical trials of personalized medicine would be concordant in all but one patient (96%) when based on the molecular profiling of tumor and paired metastasis. Our results suggest that the genotyping of primary tumor may be acceptable to guide systemic treatment if the metastatic sample is not obtainable. However, given the rare but potentially relevant divergences for some actionable driver genes, the profiling of metastatic sample is recommended.

    Full Text Available Disodium pamidronate (Aredia®, a drug of the bisphosphonate group, was administered to 20 patients with pains in the bones due to secondary deposits of lung cancer. The aim of the study was to investigate the analgesic effect of pamidronate to osteolytic metastases of lung cancer in the bone. In 16 (80% patients non-small-cell lung cancer was diagnosed, and in 4 (20% patients small-cell-lung cancer was confirmed. Intensive disseminated pains in the bones were present in all the patients. Metastases in the skeleton were confirmed by radiography and scintigraphy of the bones. Initial values of calcium in the plasma were determined in those patients. In 11 (55% patients, initial values of calcium in the serum were normal, and in 9 (45% patients, they were elevated. Patients with normal calcium values received 30 mg of pamidronate in 250 ml of normal saline, and patients with hypercalcaemia received 45-60 mg in 500 ml of normal saline. Analgesic effect of pamidronate was present in 12 (60% patients, and the completely painless state was achieved in 4 out of 12 patients. Evaluation of the pain was done by questionnaire, using a simple, descriptive scale. In all 9 (100% patients with hypercalcaemia, values of calcium in plasma were normalized. Pamidronate exerted favorable analgesic effect in the case of metastases of lung cancer in the bones in more than 50% patients. Satisfactory results were also achieved in the patients non-responsive to palliative therapy by irradiation This enables the use of opiates in lower doses.

    Highlights: • Qualitative analysis revealed significantly higher results for spatial lesion detectability of liver metastasis in CE-MRI as compared to DW-imaging (p < 0.05). • Primary visibility of liver metastases was scored equally in CE-MRI and DW-imaging. • Contrast-enhancement ratios in liver metastases reached highest values for DW-imaging (p < 0.05). • Staging of liver metastases in patients with GEP-NETs should rather be performed using a combination of PET and MRI than of PET and CT. • The combination of functional and morphologic native MR-sequences seems to be sufficient for follow-up imaging in clinical routine, especially in post-interventional follow-up. - Abstract: Purpose: To compare lesion conspicuity in patients with liver metastases arising from gastroenteropancreatic neuroendocrine tumors (GEP-NETs) using MRI, PET and CT. Materials and methods: 16 patients with GEP-NETs were evaluated using non-contrast MRI, contrast-enhanced (CE) MRI using Gd-EOB-DTPA and CE-{sup 68}Ga-DOTATOC PET. Quantitative analyses were performed by two blinded readers using ROI-analyses quantifying contrast ratios (CR) between normal liver-tissue and GEP-NET-metastases. Qualitative analyses were performed evaluating primary visibility and spatial detectability of all lesions. Results: 103 of the same liver metastases were detected on all modalities. Qualitatively, lesion conspicuity was superior on CE-MRI imaging compared to non-contrast MR-sequences (T2, DWI, fl2D, fl3D), as well as arterial- and portal-venous phase CT. Concerning detectability of lesions, CE-MRI was superior to all other modalities. The quantitative ROI-analysis demonstrated improved CR for DWI compared to all other non-contrast MR-sequences (p < 0.001). CE-MRI presented with higher CR-values compared to CE-{sup 68}Ga-DOTATOC PET/CT (p < 0.001).

    Bone metastases are common in patients with advanced breast, prostate and lung cancer. Tumor cells co-opt bone cells to drive a feed-forward cycle which disrupts normal bone remodeling to result in abnormal bone destruction or formation and tumor growth in bone. Transforming growth factor-beta (TGF-β) is a major bone-derived factor, which contributes to this vicious cycle of bone metastasis. TGF-β released from bone matrix during osteoclastic resorption stimulates tumor cells to produce osteolytic factors further increasing bone resorption adjacent to the tumor cells. TGF-β also regulates 1) key components of the metastatic cascade such as epithelial-mesenchymal transition, tumor cell invasion, angiogenesis and immunosuppression as well as 2) normal bone remodeling and coupling of bone resorption and formation. Preclinical models demonstrate that blockade of TGF-β signaling is effective to treat and prevent bone metastases as well as to increase bone mass.

    This study examines the Helix pomatia lectin (HPA) binding characteristics of metastases arising from primary breast cancer, and compares HPA binding patterns with binding of Dolichos biflorus lectin (DBA), Limax flavus lectin (LFA), and a monoclonal antibody against the Tn epitope. Of 81 blocks of metastases in a range of tissues, taken at autopsy from 46 individuals, 79% were HPA positive. No site specificity with regard to HPA binding was observed. Both HPA-positive and -negative tumour deposits were seen within a single individual. HPA-positive tumours were commonly negative for binding of sialic acid specific lectin LFA (86% were negative). Binding patterns of alpha-GalNAc specific HPA and DBA, and a monoclonal antibody against Tn epitope (GalNAc-O-Ser/Thr) were markedly different.

    1999-05-01

    A 76-year-old man insidiously developed diffuse neurological symptoms: cognitive decline, dysphagia, dysphasia and mental disturbance. Computed tomography of the cranium revealed widespread bilateral brain edema and symmetrical bilateral sphenoid wing hyperostosis. Adjacent to the hyperostosis that resembled skull base meningiomas, two separate parenchymatous temporal lobe lesions enhancing with contrast medium were observed. The patient had earlier been diagnosed to have prostatic carcinoma. Dexamethasone therapy resulted in discontinuation of the neurological symptoms. The diagnosis of metastasized adenocarcinoma of the prostate was confirmed histologically on autopsy after a sudden death from pneumonia. Intracranial metastases of prostate cancer may have a predilection site at the sphenoid wing, and can mimic a skull base meningioma. Intracranial spread of prostatic adenocarcinoma should be considered in elderly men as a treatable cause of gradual neurological deterioration, especially if cranial malignancy or hyperostosis is found.

    Full Text Available Abstract Background Chemotherapy may improve survival in patients undergoing resection of colorectal liver metastases (CLM. Neoadjuvant chemotherapy may help identify patients with occult extrahepatic disease (averting unnecessary metastasectomy, and it provides in vivo chemosensitivity data. Methods A phase II trial was initiated in which patients with resectable CLM received CPT-11, 5-FU and LV for 12 weeks. Metastasectomy was performed unless extrahepatic disease appeared. Postoperatively, patients with stable or responsive disease received the same regimen for 12 weeks. Patients with progressive disease received either second-line chemotherapy or best supportive care. The primary endpoint was disease-free survival (DFS; secondary endpoints included overall survival (OS and safety. Results 35 patients were accrued. During preoperative chemotherapy, 16 patients (46% had grade 3/4 toxicities. Resection was not possible in 5 patients. One patient died of arrhythmia following surgery, and 1 patient had transient liver failure. During the postoperative treatment phase, 12 patients (55% had grade 3/4 toxicities. Deep venous thrombosis (DVT occurred in 11 patients (34% at various times during treatment. Of those who underwent resection, median DFS was 23.0 mo. and median OS has not been reached. The overall survival from time of diagnosis of liver metastases was 51.6 mo for the entire cohort. Conclusion A short course of chemotherapy prior to hepatic metastasectomy may serve to select candidates best suited for resection and it may also direct postoperative systemic treatment. Given the significant incidence of DVT, alternative systemic neoadjuvant regimens should be investigated, particularly those that avoid the use of a central venous line.

    A 66-year-old woman was referred to our hospital with a right renal tumor in October 2010. In 1984, she underwent a mastectomy because of left breast cancer. In 2006, she underwent a lobectomy because of right lung cancer. A follow-up computed tomography of the lung cancer revealed a right renal tumor which extended to the right quadratus lumborum muscle. An exploratory laparotomy was performed and the tumor was found to be malignant by an intra-operative examination. Then, we performed a right radical nephrectomy together with the excision of quadratus lumborum muscle. Pathological examination revealed breast cancer metastasized to the pararenal fat. We could not find any invasion of the tumor into the renal parenchyma. We followed her for 2 months after the operation without any evidence of recurrence, but she suddenly expired due to an unrelated accident.

    Full Text Available Hepatocellular cancer (HCC is increasing dramatically in incidence in Europe and the United States due mainly to the hepatitis C epidemic and, to a lesser extent, increased body mass index of the population. In the fairly recent past, HCC was largely considered as untreatable due to detection mainly at late stages and lack of effective drugs for treatment. Several advances have led to changes in the prognosis of HCC. Screening of high-risk populations has allowed for earlier detection in some studies. If found at an early stage, liver transplantation not only cures the usual underlying cirrhosis but has cure rates for HCC in the range of 60% in recent series. Larger lesions can sometimes be cured by partial hepatic resection assuming the remaining liver is not too damaged to sustain liver functions after surgery. Vaccination for hepatitis B has led to reduction in the incidence of HCC. Significant improvements in antiviral treatments for both hepatitis B and hepatitis C may be having an impact on the incidence of HCC as well. It is still generally held that a finding of metastases precludes cure of HCC. We here report the case of a patient who presented with a large HCC in the context of occult hepatitis C infection. The primary tumor was resected. Over a year later, he developed a lung metastasis that was resected as well. He has not shown recurrence for 6 years since the metastasectomy. We review the recent literature on resection of lung metastases from HCC.

    Liver cancer is an aggressive malignant disease with a poor prognosis. Patients with liver cancer are usually diagnosed at an advanced stage and thus miss the opportunity for surgical resection. Chemotherapy and radiofrequency ablation, which target tumor bulk, have exhibited limited therapeutic efficacy to date. Liver cancer stem cells (CSCs) are a small subset of undifferentiated cells existed in liver cancer, which are considered to be responsible for liver cancer initiation, metastasis, relapse and chemoresistance. Elucidating liver CSC characteristics and disclosing their regulatory mechanism might not only deepen our understanding of the pathogenesis of liver cancer but also facilitate the development of diagnostic, prognostic and therapeutic approaches to improve the clinical management of liver cancer. In this review, we will summarize the recent advances in liver CSC research in terms of the origin, identification, regulation and clinical correlation.

    Three 6-month-old male beagle dogs were given a solution of 150 microng N-ethyl-N'-nitrosoguanidine (ENNG)/ml to drink ad libitum for 9 months. They all developed esophageal squamous cell carcinomas and gastric adenocarcinomas. The stomach adenocarcinomas were mostly in the antrum along the lesser curvature and were either well differentiated or poorly differentiated, with or without signet ring cells. The well-differentiated adenocarcinomas metastasized to the liver, and the poorly differentiated ones metastasized to the lymph nodes. The gastric mucosa in the antrum was atrophic, and the muscularis mucosae was fibrotic. Esophageal lesions were multicentric moderately differentiated squamous cell carcinomas, and they developed without diffuse hyperplastic changes of the epithelium. One dog with a large ulcerated carcinoma of the esophagus had metastases in the lung, liver, peritoneum, and abdominal lymph nodes. One dog also had a hemangiosarcoma with hepatic metastasis and spindle cell sarcoma in the stomach and duodenum, respectively.

    Purpose: To evaluate the accuracy and confidence in diagnosing liver metastases using combined gadolinium-EOB-DTPA (Gd-EOB-DTPA) enhanced magnetic resonance imaging (MRI)/diffusion-weighted imaging (DWI) in comparison to Gd-EOB-DTPA enhanced MRI and DWI alone. Materials and methods: Forty-three patients (age, 58 ± 13 years) with 89 liver lesions (28 benign, 61 malignant) underwent liver MRI for suspected liver metastases. Three image sets (DWI, Gd-EOB-DTPA and combined Gd-EOB-DTPA/DWI) in combination with unenhanced T1- and T2-weighted images were reviewed by three readers. Detection rates of focal liver lesions were assessed and diagnostic accuracy was evaluated by calculating the areas under the receiver-operating-characteristics curve (AUC). Confidence in diagnosis was evaluated on a 3-point scale. Histopathology and imaging follow-up served as the standard of reference. Results: Detection of liver lesions and confidence in final diagnosis for all readers were significantly higher for the combined Gd-EOB-DTPA/DWI dataset than for DWI. The combination of DWI and Gd-EOB-DTPA rendered a significantly higher confidence in final diagnosis (2.44 vs. 2.50) than Gd-EOB-DTPA alone for one reader. For two readers, accuracy in diagnosis of liver metastases was significantly higher for Gd-EOB-DTPA/DWI (AUCs of 0.84 and 0.83) than for DWI datasets (AUCs of 0.73 and 0.72). Adding DWI to Gd-EOB-DTPA did not significantly increase diagnostic accuracy as compared to Gd-EOB-DTPA imaging alone. Conclusion: Addition of DWI sequences to Gd-EOB-DTPA enhanced MRI did not significantly increase diagnostic accuracy as compared to Gd-EOB-DTPA enhanced MRI alone in the diagnosis of liver metastases. However, the increase in diagnostic confidence might justify acquisition of DWI sequences in a dedicated MRI protocol.

    The purpose was to evaluate the effectiveness of transarterial chemoembolization (TACE) in local tumor control and survival in patients with hepatic metastases from renal cell carcinoma (RCC). Prospective evaluation of TACE treatment outcome in 22 patients recruited from 1999 and 2005 was performed. The chemotherapeutic agent used was mitomycin only in 45% of the patients and mitomycin together with gemcitabine in the other 55%. The embolizing materials used in all of the patients were iodized oil (lipiodol) and degradable starch microspheres. Local response was evaluated by MRI and judged according to Response Evaluation Criteria in Solid Tumors (RECIST). Mean and median survival and survival probability after diagnosis and treatment were both calculated by Kaplan-Meier method. Partial response was achieved in 13.7%, stable disease in 59% and progressive disease in 27.3% of patients. Survival time from the diagnosis of metastases ranged from 18 to 307 months and from 2.2 to 35 months from the start of TACE treatment. The median and mean survival times from the date of diagnosis were 68.6 and 102.9 months, respectively. The median and mean survival times from the start of TACE were 8.2 and 11.7 months, respectively. Survival probability from the start of treatment was 31% after 1 year and 6% after 2 years. TACE can result in a favorable local tumor response in patients with hepatic metastases from RCC, but survival results are still limited. (orig.)

    Full Text Available Pulmonary metastases are common in patients with primary colorectal cancer (CRC. Heat-shock protein 27 (Hsp27 is upregulated in activated fibroblasts during wound healing and systemically elevated in various diseases. Cancer-associated fibroblasts (CAFs are also thought to play a role as prognostic and predictive markers in various malignancies including CRC. Surprisingly, the expression of Hsp27 has never been assessed in CAFs. Therefore we aimed to investigate the expression level of Hsp27 in CAFs and its clinical implications in patients with CRC lung metastases.FFPE tissue samples from 51 pulmonary metastases (PMs and 33 paired primary tumors were evaluated for alpha-SMA, CD31, Hsp27 and vimentin expression by immunohistochemistry and correlated with clinicopathological variables. 25 liver metastases served as control group. Moreover, serum samples (n=10 before and after pulmonary metastasectomy were assessed for circulating phospho-Hsp27 and total Hsp27 by ELISA.Stromal expression of Hsp27 was observed in all PM and showed strong correlation with alpha-SMA (P<0.001 and vimentin (P<0.001. Strong stromal Hsp27 was associated with higher microvessel density in primary CRC and PM. Moreover, high stromal Hsp27 and αSMA expression were associated with decreased recurrence-free survival after pulmonary metastasectomy (P=0.018 and P=0.008, respectively and overall survival (P=0.031 and P=0.017, respectively. Serum levels of phospho- and total Hsp27 dropped after metastasectomy to levels comparable to healthy controls.Herein we describe for the first time that Hsp27 is highly expressed in tumor stroma of CRC. Stromal α-SMA and Hsp27 expressions correlate with the clinical outcome after pulmonary metastasectomy. Moreover, serum Hsp27 might pose a future marker for metastatic disease in CRC.

    Full Text Available Background and objective Brain metastases are common in non-small-cell lung cancer (NSCLC and the prognosis is poor. Erlotinib is a specific inhibitor of the epidermal growth factor receptor-associated tyrosine kinase (EGFRTKI, which has been gradually used in the treatment for advanced NSCLC. The aim of this study is to evaluate the antitumor efficacy and its relevant factors of erlotinib in NSCLC patients with brain metastases. Methods The clinical data of 30 NSCLC patients with brain metastases were reviewed retrospectively. All of them were treated with erlotinib, given orally 150mg daily. These patients discontinued administration of erlotinib until disease progression, death or intolerable side effects. Results In terms of intracranial lesions, partial response (PR was observed in 2 patients (6.7%, with stable disease (SD in 17 patients (56.7%, for overall disease control rate (DCR of 63.4%. As for systemic disease, PR was observed in 2 patients (6.7%, with SD in 5 patients (16.7%, for overall DCR of 23.4%. There was no statistical difference in DCR among different subtypes of age, gender, smoking history, histology, PS score, the number of brain metastases, the onset of brain metastases, chemotherapy, brain radiotherapy and side effects. The median time to disease progression (MTTP and median survival time (MST was 2.4 months and 7.7 months respectively. The 1 and 2 year survival rate was 38.4% and 15.2%. The univariate analysis showed that the survival time was related to the patients’ PS score, smoking history, brain radiotherapy and chemotherapy. The multivariate analysis indicated that brain radiotherapy was the independent prognostic factor and the relationship between the survival time and smoking history was near to statistical significance. Conclusion The patients receiving brain radiotherapy may have better survival benefit. Non-smokers have a trend to survive longer than smokers. Erlotinib may be effective on brain metastases

    Full Text Available Abstract Background To estimate the costs (paid amounts of palliative radiation episodes of care (REOCs to the bone for patients with bone metastases secondary to breast or prostate cancer. Methods Claims-linked medical records from patients at 98 cancer treatment centers in 16 US states were analyzed. Inclusion criteria included a primary neoplasm of breast or prostate cancer with a secondary neoplasm of bone metastases; ≥2 visits to ≥1 radiation center during the study period (1 July 2008 through 31 December 2009 on or after the metastatic cancer diagnosis date; radiation therapy to ≥1 bone site; and ≥1 complete REOC as evidenced by a >30-day gap pre- and post-radiation therapy. Results The total number of REOCs was 220 for 207 breast cancer patients and 233 for 213 prostate cancer patients. In the main analysis (which excluded records with unpopulated costs the median number of fractions per a REOC for treatment of metastases was 10. Mean total radiation costs (i.e., radiation direct cost + cost of radiation-related procedures and visits per REOC were $7457 for patients with breast cancer and $7553 for patients with prostate cancer. Results were consistent in sensitivity analyses excluding patients with unpopulated costs. Conclusions In the US, current use of radiation therapy for bone metastases is relatively costly and the use of multi-fraction schedules remains prevalent.

    Patient records from the Guam Cancer Registry were compared with patients listed in a health department viral hepatitis case registry and the numbers of liver cancer and viral hepatitis cases were compared by ethnicity. Hepatitis C was the form of viral hepatitis most common among liver cancer cases on Guam (63.3% of viral hepatitis-associated liver cancer cases). Since viral hepatitis is an important cause of liver cancer, studies such as the present one may provide the information necessary to establish programs (screening of populations at risk and infant vaccination in the case of hepatitis B, for example) that may lessen the impact of liver cancer in the future.

    Objective. To identify a subset of breast cancer patients in whom metastatic disease is confined on- ly to the sentinel lymph node(SLn). Methods. Sentinel lymph node biopsy is performed with the injecetion of Tc99m-SC, and a gamma probe. Sentinel node biopsy was compared with standard axillary dissection for its ability to reflect the final pathological status of the axillary nodes. The factors associated with non-SLN metastases were assessed in the univariate and multivariate analysis. Result. We successfully identified 91 out of 95 patients for SLN(95.8%). The accuracy of sentinel lymph node to predict the axillary lymph node status was 93.4%. Clinical tumor size and tumor grade were proved to be the independent predictive factors for non-SLN metastases by logistic regression model. Conclusio.In most cases, the gamma probe guided method is technically feasible for detecting sentinel nodes, accurately predicting the axillary lymph node status. A subset of the patients identified who have a low risk of non-SLN metastases may not require axillary lymph node dissection.

    Full Text Available Laparoscopic approaches have been increasingly used in selected patients with either colorectal or liver cancer. However, simultaneous resection of colorectal carcinoma with synchronous liver metastases is still a subject of debate. The present case describes combined laparoscopic rectal and liver resections for a patient with primary rectal cancer and a synchronous liver metastasis utilizing a Pfannenstiel incision for specimen extraction. The operative time was 370 min and estimated blood loss was 400 mL. Postoperatively, the patient required parenteral analgesia for 48 h, resumed normal diet on day 3 and was discharged on day 7 after the operation. A laparoscopic approach utilizing a Pfannenstiel extraction incision may present an advantageous and attractive option for simultaneous laparoscopic rectal and liver resection in selected patients with the aim of improving short-term outcomes.
