    Some techniques of the most recent interventional radiology are very useful for the treatment of metastatic liver cancer and changing the style of hepatic infusion chemotherapy. This report shows our latest results and methods of hepatic infusion chemotherapy for metastatic liver cancer. 1. For the catheter placement, a new catheterization route via the left subclavian artery into the hepatic artery was developed and performed in 132 cases. Superselective catheterization succeeded in 123 cases (93.2 %). This procedure is less invasive than laparotomy and less troublesome than other percutaneous routes. 2. For useful infusion system, an implantable injection port ''Reservoir'' was developed and it was used in 87 cases. This method makes arterial infusion chemotherapy easy, and imploves their quality of life. 3. To acquire adequate drug delivery, arterial redistribution by steel coils was done, and 109 arteries in 80 cases were occluded. This method is very useful to make multiple hepatic artery single and it is important to avoid gasroduodenal complications. 4. Now, using these techniques, the phase II study of 5FU, ADM, MMC combined hepatic infusion in patients with non-resectable metastatic liver cancer is done. Up to this time, such a phase study on arterial infusion chemotherapy was difficult because of technical problems, but these new techniques make it possible. In conclusion, these new methods change the style and conception of hepatic infusion, and these make much progress on the treatment of patients with metastatic liver cancer. (author)

    The incidence of hepatocellular carcinoma is increasing. Most patients present beyond potentially curative options and are usually affected by underlying cirrhosis. In this scenario, transarterial therapies, such as radioembolization, are rapidly gaining acceptance as a potential therapy for hepatocellular carcinoma and liver metastases. Radioembolization is a catheter-based liver-directed therapy that involves the injection of micron-sized embolic particles loaded with a radioisotope by use of percutaneous transarterial techniques. Cancer cells are preferentially supplied by arterial blood and normal hepatocytes by portal venous blood; therefore, radioembolization specifically targets tumor cells with a high dose of lethal radiation and spares healthy hepatocytes. The antitumor effect mostly comes from radiation rather than embolization. The most commonly used radioisotope is yttrium-90. The commercially available devices are TheraSphere (glass based; MDS Nordion, Ottawa, Canada) and SIR-Sphere (resin based; Sirtex, Lane Cove, Australia). The procedure is performed on an outpatient basis. The incidence of complications is comparatively less than other locoregional therapies and may include nausea, fatigue, abdominal pain, hepatic dysfunction, biliary injury, fibrosis, radiation pneumonitis, gastrointestinal ulcers, and vascular injury. However, these complications can be avoided by meticulous pretreatment assessment, careful patient selection, and adequate dosimetry. This article focuses on both the technical and clinical aspects of radioembolization with emphasis on patient selection, uses and complications. Copyright © 2011 Elsevier Inc. All rights reserved.

    In this paper, automated extraction of metastatic liver cancer regions from abdominal contrast X-ray CT images is investigated. Because even in Japan, cases of metastatic liver cancers are increased due to recent Europeanization and/or Americanization of Japanese eating habits, development of a system for computer aided diagnosis of them is strongly expected. Our automated extraction procedure consists of following four steps; liver region extraction, density transformation for enhancement of cancer regions, segmentation for obtaining candidate cancer regions, and reduction of false positives by shape feature. Parameter values used in each step of the procedure are decided based on density and shape features of typical metastatic liver cancers. In experiments using practical 20 cases of metastatic liver tumors, it is shown that 56% of true cancers can be detected successfully from CT images by the proposed procedure. (author)

  5. Fatal Acute Liver Failure as a Consequence of Regorafenib Treatment in a Metastatic Colon Cancer

    Directory of Open Access Journals (Sweden)

    2017-08-01

    Full Text Available Regorafenib is a multikinase inhibitor which showed benefits in pretreated metastatic colorectal cancer patients. Hepatotoxicity has been described as a frequent side effect. We report the case of a 65-year-old patient presenting with jaundice, fever, and hepatocellular insufficiency which led to death of the patient. She had previously been treated with several lines of chemotherapy for sub- and diaphragmatic ganglionic metastases of a colon adenocarcinoma. There were no liver metastases. The fatal liver failure occurred at the beginning of treatment with regorafenib at a dosage of 3 tablets per day. No concomitant treatment was given, and other causes of liver damage were eliminated. The liver biopsy showed hepatocyte necrosis with lymphocyte infiltration. This observation illustrates the risk of severe hepatic involvement typically occurring within the first 2 months of treatment. Monitoring liver biology every 2 weeks is essential during the first 2 months to detect any hepatotoxicity.

    Abstract Rationale: Regorafenib is effective for metastatic colorectal cancer but its toxicity such as hemorrhage should be considered. The safety of regorafenib for the patient with the liver disease is not known. Patient concerns: Seventy-one-year old man of colon cancer had myodesopsia and blood stool after 14 days from the initiation of regorafenib administration with 50% dose reduction due to liver dysfunction. Diagnoses: Fundus examination revealed hemorrhage of the retinal vein. Interventions: Regorafenib treatment was discontinued and observational therapy was pursued. Outcomes: Retinal and gastrointestinal hemorrhage resolved in 1 week. Lessons: Retinal hemorrhage should be considered as the differential diagnosis of myodesopsia in the patient treated by regorafenib. Safety and pharmacokinetic of continuous regorafenib administration for patients with liver dysfunction remains to be clarified. PMID:29049226

    Liver cancer has a very dismal prognosis due to lack of effective therapy. Here, we studied the therapeutic effects of hyper-interleukin15 (hyper-IL-15), which is composed of IL-15 and the sushi domain of the IL-15 receptor α chain, on metastatic and autochthonous liver cancers. Liver metastatic tumour models were established by intraportally injecting syngeneic mice with murine CT26 colon carcinoma cells or B16-OVA melanoma cells. Primary hepatocellular carcinoma (HCC) was induced by diethylnitrosamine (DEN). A hydrodynamics-based gene delivery method was used to achieve sustained hyper-IL-15 expression in the liver. Liver gene delivery of hyper-IL-15 robustly expanded CD8(+) T and NK cells, leading to a long-term (more than 40 days) accumulation of CD8(+) T cells in vivo, especially in the liver. Hyper-IL-15 treatment exerted remarkable therapeutic effects on well-established liver metastatic tumours and even on DEN-induced autochthonous HCC, and these effects were abolished by depletion of CD8(+) T cells but not NK cells. Hyper-IL-15 triggered IL-12 and interferon-γ production and reduced the expression of co-inhibitory molecules on dendritic cells in the liver. Adoptive transfer of T cell receptor (TCR) transgenic OT-1 cells showed that hyper-IL-15 preferentially expanded tumour-specific CD8(+) T cells and promoted their interferon-γ synthesis and cytotoxicity. Liver delivery of hyper-IL-15 provides an effective therapy against well-established metastatic and autochthonous liver cancers in mouse models by preferentially expanding tumour-specific CD8(+) T cells and promoting their anti-tumour effects.

    Colon cancer, though already metastatic, may still be curable through multi-modality approaches, which require combined planning between medical and surgical oncologists. Retrospective surgical series have historically shown 5-year survival or “cures” for 30% to 50% of patients with solitary or a few resectable liver metastases. The role of adjuvant chemotherapy in this setting has been poorly defined. A recent European Organization for Research and Treatment of Cancer (EORTC) study randomize...

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

    Colorectal cancer (CRC) is an aggressive disease in which patients usually die due to its metastatic progression to the liver. Up to date, irinotecan is one of the most used chemotherapeutic agents to treat CRC metastasis with demonstrated efficacy. However, the severity of the side effects constitute the main limitation to its use in the treatment. Consequently, new complementary therapies are being developed to avoid these adverse effects while maintaining the efficacy of the antitumoral dr...

    A 66-year-old female presented with the main complaint of defecation trouble and abdominal distention. With diagnosis of rectal cancer, cSS, cN0, cH0, cP0, cM0 cStage II, Hartmann's operation with D3 lymph node dissection was performed and a para-aortic lymph node and a disseminated node near the primary tumor were resected. Histological examination showed moderately differentiated adenocarcinoma, pSS, pN3, pH0, pP1, pM1 (para-aortic lymph node, dissemination) fStage IV. After the operation, the patient received chemotherapy with FOLFIRI regimen. After 12 cycles of FOLFIRI regimen, computed tomography (CT) detected an 11 mm of liver metastasis in the postero-inferior segment of right hepatic lobe. With diagnosis of liver metastatic recurrence, we performed partial hepatectomy. Histological examination revealed moderately differentiated adenocarcinoma as a metastatic rectal cancer with cut end microscopically positive. After the second operation, the patient received chemotherapy with TS1 alone for 2 years. Ten months after the break, CT detected a 20 mm of para-aortic lymph node metastasis and a 10 mm of lymph node metastasis at the hepato-duodenal ligament. With diagnosis of lymph node metastatic recurrences, we performed lymph node dissection. Histological examination revealed moderately differentiated adenocarcinoma as metastatic rectal cancer in para-aortic and hepato-duodenal ligament areas. After the third operation, we started chemotherapy with modified FOLFOX6 regimen. After 2 cycles of modified FOLFOX6 regimen, due to the onset of neutropenia and liver dysfunction, we switched to capecitabine alone and continued it for 6 mo and then stopped. Eleven months after the break, CT detected two swelling 12 mm of lymph nodes at the left supraclavicular region. With diagnosis of Virchow lymph node metastatic recurrence, we started chemotherapy with capecitabine plus bevacizumab regimen. Due to the onset of neutropenia and hand foot syndrome (Grade 3), we managed to

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

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

    1997-01-01

    Tetrofosmin (1,2-bis[bis(2-ethoxyethyl)phosphino]ethan) is currently under investigation for its tumor seeking properties, encouraged by the incidental finding of a malignant breast-lesion on myocardial scintigraphy in 1995 (Rambaldi et al, Clin Nucl Med 1995) using tetrofosmin. Recent reports have confirmed tetrofosmins role in detecting primary tumors in breast cancer. To investigate whether tetrofosmin significantly helps detect metastatic lesions in such patients we performed tetrofosmin scintigraphy in 21 patients with metastatic breast cancer. Patients and methods: Median age of patients was 61 years. In one patient the primary site was unknown. All patients had at least one distant metastasis. 550 MBq of 99m-Tc-tetrofosmin was administered ten minutes before imaging was begun. After obtaining a planar image, a single photon emission computed tomography (SPECT) was done of every suspected distant lesion. CT-scans or MRI were used to confirm positive correlation with tetrofosmin scintigraphy. Results: Tetrofosmin scintigraphy correctly diagnosed metastatic disease in 71 % of patients with no false negative and two false positive results. In each of the two patients a mediastinal hot spot suggestive of malignancy was found, but none of those lesions could be proven using CT scans. Excluding patients with liver metastasis from the present analysis, 91 % of all metastasis would have been correctly diagnosed. The first patient in our department had a large metastasis in the upper mediastinum which could not be seen on regular chest films. In the patient in whom the primary site of cancer was unknown, tetrofosmin scintigraphy showed three consecutive nodules in the left mammary, gland in a coronary fashion. Magnetic resonance imaging then confirmed two single nodules of 0.8 cm in diameter. Conclusions: Evaluating 21 patients, the present study was performed to investigate tetrofosmins properties of detecting metastatic lesions in patients with breast cancer. A 91

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

    A series of 59 consecutive cases of histologically proven breast cancer were admitted.for radiotherapy. The group was mostly composed of stage III/TNM. The patients were studied with a scintillation camera and a 1600-channel analyser after i. v. injection of 2mCi of colloidal {sup 99m}Tc. Up to 104 counts were accumulated in one of the elements of the analyser matrix and were then transferred to computer-compatible punched tape. The data could be presented immediately in a number of different ways: (a) as conventional scintigraphic pictures on the camera's oscilloscope; (b) as nine pictures from the analyser's oscilloscope with 10, 20, 30... 90% of the counts erased; and (c) as one picture with those four selected levels of erase which were considered best, for a given case. In addition, progressive increase of exposure and defocusing of each level was possible. Examination with colloidal {sup 99m}Tc was found to be a safe method for the detection of malignant secondaries in the liver because of the low irradiation dose to the patient. The high radioactivity accumulated in the liver means a short examination time and the elimination of statistical fluctuations. Furthermore, the stored information enables the time-consuming work to be done in the patient's absence. (author)

    Forty patients with asymptomatic metastatic cancer to the liver discovered at the time of laparotomy were treated by combined intrahepatic arterial chemotherapy and internal irradiation in the form of 90 Y microspheres. One group of 25 patients were treated by a catheter inserted at the time of operation and received 100 mCi; of 90 Y microspheres and 5-fluorouracil on a continuing basis. They survived an average of 26 mo (varying from 9 to 60 mo). The second series of 15 patients referred after surgery were treated by the percutaneous insertion of the catheter into the hepatic artery and received a bolus of combined chemotherapy consisting of PlatinolTM, Methotrexate, and 5-fluorouracil. They survived an average of 31 mo, which varied from 12 to 60 mo. The dose of 100 mCi of 90 Y was well tolerated by the liver. Prospective studies are in progress, limiting the treatment to the internal irradiation to determine its precise role in the overall treatment of metastatic cancer to the liver

    Background: Liver-limited disease (LLD) denotes a specific subgroup of metastatic colorectal cancer (mCRC) patients. Patients and Methods: A total of 479 patients with unresectable mCRC from an irinotecan-based randomised phase III trial were evaluated. Patients with LLD and non-LLD and hepatic resection were differentiated. Based on baseline patient characteristic, prognostic factors for hepatic resection were evaluated. Furthermore, prognostic factors for median overall survival (OS) were estimated via Cox regression in LLD patients. Results: Secondary liver resection was performed in 38 out of 479 patients (resection rate: 7.9%). Prognostic factors for hepatic resection were LLD, lactate dehydrogenase (LDH), node-negative primary, alkaline phosphatase (AP) and Karnofsky performance status (PS). Median OS was significantly increased after hepatic resection (48 months), whereas OS in LLD (17 months) and non-LLD (19 months) was comparable in non-resected patients. With the inapplicability of Koehne's risk classification in LLD patients, a new score based on only the independent prognostic factors LDH and white blood cell (WBC) provided markedly improved information on the outcome. Conclusion: Patients undergoing hepatic resection showed favourable long-term survival, whereas non-resected LLD patients and non-LLD patients did not differ with regard to progression-free survival and OS. The LDH levels and WBC count were confirmed as prognostic factors and provide a useful and simple score for OS-related risk stratification also in LLD. PMID:23963138

    Radioembolization with the yttrium-90 (Y-90) microspheres is being used increasingly more often in the treatment of patients with primary or metastatic liver cancer. Although technetium-99m macroaggregated albumin (Tc-99m MAA) scintigraphy performed following diagnostic angiography has an important role in predicting the effectiveness of treatment and in dose estimation, the number of studies using quantitative assessment of Tc-99m MAA scintigraphy is limited in this field. In the present study, the aim was to assess whether a tumor dose is required to obtain objective tumor response and to check whether this threshold value is predictive in terms of tumor response, survival, and liver toxicity by using Tc-99m MAA single-photon emission computed tomography (SPECT) images. Overall, 54 patients (20 women and 34 men; median age: 60 years) who underwent Y-90 Resin (SIR-Spheres) and Glass (TheraSphere) microsphere treatment with a diagnosis of unresectable liver cancer between August 2010 and April 2013 were included in the study. The mean doses to normal liver and tumor were estimated for each patient using Tc-99m MAA SPECT images and the medical internal radiation dosimetry method. The responses were assessed according to Response Evaluation Criteria In Solid Tumors (RECIST) and European Organisation for Research and Treatment of Cancer (EORTC) criteria. Kaplan-Meier survival curves and univariate Cox regression analysis were used in survival analysis. The relationship between treatment response and other parameters included was assessed using logistic regression analysis. The variables with a P value less than 0.01 in univariate analysis were assessed with multivariate analysis. Fifty-four Y-90 microsphere treatments (eight by using a Y-90 glass microsphere and 46 by using a Y-90 resin microsphere) were performed. In the multivariate analysis, the only parameter related to response was tumor dose (P<0.01). With a tumor dose of 280 Gy or higher, objective tumor

    Full Text Available Abstract Background Treatment records and follow-up data on 40 patients with primary and metastatic liver malignancies who underwent a single whole-liver treatment with Y-90 resin microspheres (SIR-Spheres® Sirtex Medical, Lake Forest, IL were retrospectively reviewed. The objective of the study was to evaluate the anatomic and physiologic determinants of radiation dose distribution, and the dose response of tumor and liver toxicity in patients with liver malignancies who underwent hepatic arterial Y-90 resin microsphere treatment. Methods Liver and tumor volume calculations were performed on pre-treatment CT scans. Fractional tumor and liver flow characteristics and lung shunt fractions were determined using hepatic arterial Tc-99m MAA imaging. Absorbed dose calculations were performed using the MIRD equations. Liver toxicity was assessed clinically and by liver function tests. Tumor response to therapy was assessed by CT and/or tumor markers. Results Of the 40 patients, 5 had hepatocellular cancer (HCC, and 35 had metastatic liver tumors (15 colorectal cancer, 10 neuroendocrine tumors, 4 breast cancer, 2 lung cancer, 1 ovarian cancer, 1 endometrial cancer, and 2 unknown primary adenocarcinoma. All patients were treated in a salvage setting with a 3 to 80 week follow-up (mean: 19 weeks. Tumor volumes ranged from 15.0 to 984.2 cc (mean: 294.9 cc and tumor to normal liver uptake ratios ranged from 2.8 to 15.4 (mean: 5.4. Average administered activity was 1.2 GBq (0.4 to 2.4 GBq. Liver absorbed doses ranged from 0.7 to 99.5 Gy (mean: 17.2 Gy. Tumor absorbed doses ranged from 40.1 to 494.8 Gy (mean: 121.5 Gy. None of the patients had clinical venoocclusive disease or therapy-induced liver failure. Seven patients (17.5 % had transient and 7 patients (17.5 % had persistent LFT abnormalities.

    For patients with metastatic colon cancer, management has evolved from resecting a single liver metastasis and having only one chemotherapy medicine, to resecting multiple metastases including those outside the liver as well as using combination chemotherapy (based on recent supportive trials) to improve outcomes. This success has also raised many questions, including the role of adjuvant chemotherapy to downstage borderline resectable tumors, whether patients who receive preoperative chemoth...

    Objective: To evaluate the point plaster therapy with ginger powder combined with ondansetron hydrochloride in preventing nausea and vomiting usually occurred after platinum-based interventional chemotherapy in patients with primary or metastatic liver cancer, and to compared its effectiveness with that by using ondansetron hydrochloride only. Method: Sixty-two patients with primary or metastatic liver cancer, who were scheduled to receive platinum-based interventional chemotherapy, were randomly and equally divided into two groups with 31 cases in each group. The patients in the study group (n = 31) were given point plaster therapy, i.e. externally applying ginger powder (20 g) to the point of Shenque, for four days together with arterial infusion of ondansetron hydrochloride (8 mg) during interventional procedure,while the patients in the control group (n = 31) were given point plaster therapy with placebo (potato powder) together with arterial infusion of ondansetron hydrochloride (8 mg) during interventional procedure. The questionnaire of INVR (index form for evaluating nausea and vomiting) was used to assess the effectiveness, and the results were compared between two groups. Results: The incidence of nausea and vomiting in study group was significantly lower than that in control group at all observed points of time during the period of 0 -72 hours after the treatment (P 0.05). After the treatment the scores of nausea, vomiting and retching in the study group were 0.45, 0.25 and 0.19 respectively, while these in the control group were 2.77, 0.87 and 0.97 respectively, the differences between two groups were statistically significant (P < 0.05). Conclusion: The external application of ginger powder to points of Shenque can markedly decrease the incidence and severity of nausea and vomiting after platinum-based interventional chemotherapy in patients with primary or metastatic liver cancer.

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

    Full text: Yttrium-90 labelled microspheres (SIR-Spheres) delivered via the hepatic artery are used in the treatment of non-resectable metastatic liver disease, with the spheres becoming trapped in hepatic tumours. Sixteen patients (9 males, 7 females, 43-80 years) were assessed for therapy. All had failed chemotherapy and had evidence of progressive disease. Extrahepatic disease, ascites and abnormal liver function were first taken into consideration, eliminating 3 patients. The remaining patients underwent a breakthrough scan where Tc99m-MAA was administered intra-hepatically. This scan was used to calculate the level of shunting to the lungs, stomach and bowel and was co-registered with a recent CT scan to confirm MAA uptake corresponded with tumour sites. These breakthrough scans excluded 6 patients, 1 demonstrating high lung activity and 5 not showing focal metastatic accumulation of Tc-99m MAA. Another patient declined. Post-treatment, 4 patients spent 1-2 nights hospitalised for observation with no complications. One patient experienced pain requiring narcotic analgesia and 3 nights in hospital, the other experienced pain, fever, rigours, nausea and vomiting requiring 5 nights hospitalisation. For all patients, liver and bone marrow function was relatively unchanged 1 week post-therapy indicating no acute toxicity. Since receiving therapy, 2 patients survived less than 2 months, dying of disease progression. Two had progressive extrahepatic disease, and the remaining 2 patients, who also received chemotherapy, currently report a good quality of life, although no objective data is currently available to evaluate tumour response. In this selected group of patients, SIR therapy appears to have limited toxicity with yet to be demonstrated efficacy. Copyright (2002) The Australian and New Zealand Society of Nuclear Medicine Inc

    In Canada and Europe, yttrium-90 microspheres (TheraSphere); MDS Nordion, Ottawa, Canada) are a primary treatment option for primary and secondary hepatic malignancies. We present data from 30 patients with hepatocellular carcinoma (HCC) and metastatic liver disease treated with TheraSphere from a single academic institution to evaluate the angiographically evident embolization that follows treatment. Seven interventional radiologists from one treatment center compared pretreatment and posttreatment angiograms. The reviewers were blinded to the timing of the studies. The incidence of postembolization syndrome (PES) was determined as well as objective tumor response rates by the World Health Organization (WHO), Response Evaluation Criteria in Solid Tumors (RECIST), and European Association for the Study of the Liver (EASL) criteria. There were 420 independent angiographic observations that were assessed using the chi-squared statistic. The pretreatment and posttreatment angiograms could not be correctly identified on average more than 43% of the time (p = 0.0004). The postprocedure arterial patency rate was 100%. The objective tumor response rates for all patients were 24%, 31%, and 72% for WHO, RECIST, and EASL criteria, respectively. All of the patients tolerated the procedure without complications and were treated on an outpatient basis, and four patients had evidence of PES. This treatment method does not result in macroscopic embolization of the hepatic arteries, thereby maintaining hepatic tissue perfusion. These data support the principle that the favorable response rates reported with TheraSphere are likely due to radiation and microscopic embolization rather than flow-related macroscopic embolization and ischemia.

    Full Text Available Abstract Purpose of the study. Improvement of results of treatment in patients with primary and metastatic liver cancer by decreasing the risk of post-resection liver failure on the basis of the evaluation of the functional reserves of the liver.Materials and Methods. The study included two independent samples of patients operated about primary or metastatic lesions of the liver at the Department of abdominal Oncology, P. A. Hertsen MORI. The first group included 53 patients who carried out 13C-breath test metallimovie and dynamic scintigraphy of the liver in the preoperative stage in addition to the standard algorithm of examination. Patients of the 2nd group (n=35 had a standard clinical and laboratory examination, the patients were not performed the preoperative evaluation of the functional reserve of the liver, the incidences of total bilirubin, albumin and prothrombin time did not reveal a reduction of liver function. Post-resection liver failure have been established on the basis of the 50/50 criterion in the evaluation on day 5 after surgery.Results. Analysis of operating characteristics of the functional tests showed the absolute methacin breath test sensitivity (SE≥100%, high specificity (SP≥67% of scintigraphy of the liver and the negative predictive value of outcome (VP≥100% at complex use of two diagnostic methods. The incidence of PROPS in the study group was significantly 2 times higher in the control group –15,1% and 26.8%, respectively (p<0.001.Conclusion. The combination of preoperative dynamic scintigraphy of the liver with carrying out 13C-breath methacin test allows you to conduct a comprehensive evaluation of the liver functional reserve and can significantly improve preoperative evaluation and postoperative results of anatomic resection in patients with primary and metastatic liver lesions.

    To investigate whether quantifications of apparent diffusion coefficient (ADC) on diffusion-weighted imaging (DWI) can predict overall survival (OS) in patients with liver-predominant metastatic colorectal cancer (CRC) following selective internal radiation therapy with {sup 90}Yttrium-microspheres (SIRT). Forty-four patients underwent DWI 19 ± 16 days before and 36 ± 10 days after SIRT. Tumour-size and intratumoral minimal ADC (minADC) values were measured for 132 liver metastases on baseline and follow-up DWI. Optimal functional imaging response to treatment was determined by receiver operating characteristics and defined as ≥22 % increase in post-therapeutic minADC. Survival analysis was performed with the Kaplan-Meier method and Cox-regression comparing various variables with potential impact on OS. Median OS was 8 months. The following parameters were significantly associated with median OS: optimal functional imaging response (18 vs. 5 months; p < 0.001), hepatic tumour burden <50 % (8 vs. 5 months; p = 0.018), Eastern Cooperative Oncology Group performance scale <1 (10 vs. 4 months; p = 0.012) and progressive disease according to Response and Evaluation Criteria in Solid Tumours (8 vs. 3 months; p = 0.001). On multivariate analysis, optimal functional imaging response and hepatic tumour burden remained independent predictors of OS. Functional imaging response assessment using minADC changes on DWI may predict survival in CRC shortly after SIRT. (orig.)

    The aim of this study was to evaluate the predictive value of early metabolic response 4 weeks post-treatment using {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT in patients with unresectable hepatic metastases of colorectal cancer (CRC) undergoing radioembolization (RE) with {sup 90}Y-labelled microspheres. A total of 51 consecutive patients with liver-dominant metastases of CRC were treated with RE and underwent {sup 18}F-FDG PET/CT at baseline and 4 weeks after RE. In each patient, three hepatic metastases with the highest maximum standardized uptake value (SUV{sub max}) were selected as target lesions. Metabolic response was defined as >50 % reduction of tumour to liver ratios. Survival analyses using Kaplan-Meier and multivariate analyses were performed to identify prognostic factors for overall survival (OS). Investigated baseline characteristics included age (>60 years), performance status (Eastern Cooperative Oncology Group >1), bilirubin (>1.0 mg/dl), hepatic tumour burden (>25 %) and presence of extrahepatic disease. The median OS after RE was 7 months [95 % confidence interval (CI) 5-8]; early metabolic responders (n = 33) survived longer than non-responders (p < 0.001) with a median OS of 10 months (95 % CI 3-16) versus 4 months (95 % CI 2-6). Hepatic tumour burden also had significant impact on treatment outcome (p < 0.001) with a median OS of 5 months (95 % CI, 3-7) for patients with >25 % metastatic liver replacement vs 14 months (95 % CI 6-22) for the less advanced patients. Both factors (early metabolic response and low hepatic tumour burden) remained as independent predictors of improved survival on multivariate analysis. These are the first findings to show that molecular response assessment in CRC using {sup 18}F-FDG PET/CT appears feasible as early as 4 weeks post-RE, allowing risk stratification and potentially facilitating early response-adapted treatment strategies.

    Our aim was to provide further evidence for the efficacy/safety of radioembolization using yttrium-90-resin microspheres for unresectable chemorefractory liver metastases from colorectal cancer (mCRC). We followed 104 consecutively treated patients until death. Overall survival (OS) was calculated from the day of the first radioembolization procedure. Response was defined by changes in tumour volume as defined by Response Evaluation Criteria in Solid Tumours (RECIST) v1.0 and/or a ≥30 % reduction in serum carcinoembryonic antigen (CEA) at 3 months. Survival varied between 23 months in patients who had a complete response to prior chemotherapy and 13 months in patients with a partial response or stable disease. Median OS also significantly improved (from 5.8 months to 17.1 months) if response durability to radioembolization extended beyond 6 months. Patients with a positive trend in CEA serum levels (≥30 % reduction) at 3 months post-radioembolization also had a survival advantage compared with those who did not: 15.0 vs 6.7 months. Radioembolization was well tolerated. Grade 3 increases in bilirubin were reported in 5.0 % of patients at 3 months postprocedure. After multiple chemotherapies, many patients still have a good performance status and are eligible for radioembolization. This single procedure can achieve meaningful survivals and is generally well tolerated. (orig.)

    Purpose: The introduction of radioembolization with microspheres represents a significant step forward in the treatment of patients with metastatic disease to the liver. This technique uses semiempirical formulae based on body surface area or liver and target volumes to calculate the required total activity for a given patient. However, this treatment modality lacks extremely important information, which is the three-dimensional (3D) dose delivered by microspheres to different organs after their administration. The absence of this information dramatically limits the clinical efficacy of this modality, specifically the predictive power of the treatment. Therefore, the aim of this study is to develop a 3D dose calculation technique that is based on the PET imaging of the infused microspheres.Methods: The Fluka Monte Carlo code was used to calculate the voxel dose kernel for {sup 90}Y source with voxel size equal to that of the PET scan. The measured PET activity distribution was converted to total activity distribution for the subsequent convolution with the voxel dose kernel to obtain the 3D dose distribution. In addition, dose-volume histograms were generated to analyze the dose to the tumor and critical structures.Results: The 3D inpatient dose distribution can be reconstructed from the PET data of a patient scanned after the infusion of microspheres. A total of seven patients have been analyzed so far using the proposed reconstruction method. Four patients underwent treatment with SIR-Spheres for liver metastases from colorectal cancer and three patients were treated with Therasphere for hepatocellular cancer. A total of 14 target tumors were contoured on post-treatment PET-CT scans for dosimetric evaluation. Mean prescription activity was 1.7 GBq (range: 0.58–3.8 GBq). The resulting mean maximum measured dose to targets was 167 Gy (range: 71–311 Gy). Mean minimum dose to 70% of target (D70) was 68 Gy (range: 25–155 Gy). Mean minimum dose to 90% of target

    Full Text Available Objective To investigate the value of contrast-enhanced ultrasound (CEUS in the differential diagnosis of single metastatic hepatic carcinoma (MHC and solitary necrotic nodule of the liver (SNNL. MethodsA retrospective analysis was performed for 12 patients with single MHC and 16 patients with SNNL who showed circular enhancement in arterial phase on CEUS. Age, size of lesion, and findings of two-dimensional gray-scale ultrasound and CEUS were compared between the two groups. The two-independent-samples t-test was used for comparison between groups, and the paired t-test was used for comparison within each group. ResultsThe MHC group had a significantly higher mean age than the SNNL group (60.2±11.3 years vs 41.0±9.1 years, t=4.970, P<0.001. The mean diameter of lesion was 2.86±1.22 cm in the MHC group and 2.97±0.96 cm in the SNNL group, and showed no significant difference between the two groups (t=-0.269, P=0.790. In the MHC group, the lesions had complex and uneven echoes and blurred boundaries, while in the SNNL group, most lesions were in the right lobe and were hypoechoic with clear boundaries. No blood flow signals were detected on CDFI in these two groups. Both groups had circular enhancement around the lesions in arterial phase on CEUS, and the mean thickness showed a significant difference between the MHC group and the SNNL group (5.00±1.69 mm vs 2.37±0.87 mm, t=5.374, P<0001. In the MHC group, the area in lesions without enhancement in delayed phase was significantly larger than that in arterial phase (t=-4.508, P=0001, while in the SNNL group, the area in lesions without enhancement showed no significant difference between delayed phase and arterial phase (t=-0.449, P=0.660. ConclusionThe thickness of circular enhancement in arterial phase on CEUS and the presence or absence of the enlargement in the area without enhancement contributes to the differential diagnosis of single MHC and SNNL.

    The common sites of breast cancer metastases include bones, lung, brain, and liver. Renal metastasis from the breast is rare. We report a case of breast cancer metastatic to the kidney with extension into the renal vein. A 40-year-old woman had undergone left mastectomy for breast cancer at the age of 38. A gastric tumor, which was later proved to be metastasis from breast cancer, was detected by endoscopy. Computed tomography performed for further examination of the gastric tumor revealed a large left renal tumor with extension into the left renal vein. It mimicked a primary renal tumor. Percutaneous biopsy of the renal tumor confirmed metastasis from breast cancer. Surgical intervention of the stomach and the kidney was avoided, and she was treated with systemic chemotherapy. Breast cancer metastatic to the kidney may present a solitary renal mass with extension into the renal vein, which mimics a primary renal tumor.

    While breast cancers with distant metastasis at presentation (de novo metastasis) harbor significantly inferior clinical outcomes, there have been limited studies analyzing the clinicopathologic characteristics in this subset of patients. In this study, we analyzed 6126 breast cancers diagnosed between 1998 and 2013 to identify factors associated with de novo metastatic breast cancer. When compared to patients without metastasis at presentation, race, histologic grade, estrogen/progesterone receptor (ER/PR) and HER2 statuses were significantly associated with de novo metastasis in the entire cohort, whereas age, histologic grade, PR and HER2 status were the significant parameters in the subset of patients with locally advanced breast cancer (Stage IIB/III). The patients with de novo metastatic breast cancer had a significant older mean age and a lower proportion of HER2-positive tumors when compared to those with metastatic recurrence. Further, the HER2-rich subtype demonstrated a drastically higher incidence of de novo metastasis when compared to the luminal and triple-negative breast cancers in the entire cohort [odds ratio (OR)=5.68 and 2.27, respectively] and in the patients with locally advanced disease (OR=4.02 and 2.12, respectively), whereas no significant difference was seen between de novo metastatic cancers and those with metastatic recurrence. Moreover, the luminal and HER2-rich subtypes showed bone-seeking (OR=1.92) and liver-homing (OR=2.99) characteristics, respectively, for the sites of de novo metastasis, while the latter was not observed in those with metastatic recurrence. Our data suggest that an algorithm incorporating clinicopathologic factors, especially histologic grade and receptor profile, remains of significant benefit during decision making in newly diagnosed breast cancer in the pursuit of precision medicine.

    Metastatic melanoma is a donor-derived malignancy that has rarely been reported in liver allograft recipients. We present a case of a transmitted donor-derived melanoma to a liver allograft recipient in whom the diagnosis was established by polymerase chain reaction-based DNA fingerprinting. A 52-year-old African-American man underwent a successful orthotropic liver transplant for alcohol-induced cirrhosis. One year after the orthotropic liver transplant, he presented at our institution with diffuse abdominal pain, and a computed tomography scan of the abdomen and chest showed innumerable masses diffusely involving the liver and multiple subcutaneous nodules in the abdominal and chest wall. A liver biopsy confirmed the diagnosis of metastatic melanoma. The origin of melanoma was traced to the donor by DNA fingerprinting of the native liver, the donor liver, and the donor gallbladder. Chemotherapy was initiated with temozolomide (75 mg/m² daily) and thalidomide (50 mg daily), to which he responded within 8 weeks with radiologic improvement in metastatic lesions. Tacrolimus was switched to sirolimus because of renal insufficiency as well as reported effectiveness against melanoma. Our patient survived for 9 months after the diagnosis of metastatic melanoma. He ultimately died of brain metastases. Donor-derived metastatic melanoma is a rare cancer with the highest transmission and mortality rates, which requires better recognition. Prompt diagnosis of donor-derived melanoma is critical and can be achieved reliably with polymerase chain reaction-based DNA analysis. Management options after diagnosis include de-escalation of immunosuppression, with or without urgent organ removal or retransplant. The roles of chemotherapy, immunotherapy, and radiotherapy require further study.

    In Canada and Europe, yttrium-90 microspheres (TheraSphere); MDS Nordion, Ottawa, Canada) are a primary treatment option for primary and secondary hepatic malignancies. We present data from 30 patients with hepatocellular carcinoma (HCC) and metastatic liver disease treated with TheraSphere from a single academic institution to evaluate the angiographically evident embolization that follows treatment. Seven interventional radiologists from one treatment center compared pretreatment and posttreatment angiograms. The reviewers were blinded to the timing of the studies. The incidence of postembolization syndrome (PES) was determined as well as objective tumor response rates by the World Health Organization (WHO), Response Evaluation Criteria in Solid Tumors (RECIST), and European Association for the Study of the Liver (EASL) criteria. There were 420 independent angiographic observations that were assessed using the chi-squared statistic. The pretreatment and posttreatment angiograms could not be correctly identified on average more than 43% of the time (p = 0.0004). The postprocedure arterial patency rate was 100%. The objective tumor response rates for all patients were 24%, 31%, and 72% for WHO, RECIST, and EASL criteria, respectively. All of the patients tolerated the procedure without complications and were treated on an outpatient basis, and four patients had evidence of PES. This treatment method does not result in macroscopic embolization of the hepatic arteries, thereby maintaining hepatic tissue perfusion. These data support the principle that the favorable response rates reported with TheraSphere are likely due to radiation and microscopic embolization rather than flow-related macroscopic embolization and ischemia

    MUC13 is a newly identified transmembrane mucin. Although MUC13 is known to be overexpressed in ovarian and gastric cancers, limited information is available regarding the expression of MUC13 in metastatic colon cancer. Herein, we investigated the expression profile of MUC13 in colon cancer using a novel anti-MUC13 monoclonal antibody (MAb, clone ppz0020) by immunohistochemical (IHC) analysis. A cohort of colon cancer samples and tissue microarrays containing adjacent normal, non-metastatic colon cancer, metastatic colon cancer, and liver metastasis tissues was used in this study to investigate the expression pattern of MUC13. IHC analysis revealed significantly higher (pcolon cancer samples compared with faint or very low expression in adjacent normal tissues. Interestingly, metastatic colon cancer and liver metastasis tissue samples demonstrated significantly (pcolon cancer and adjacent normal colon samples. Moreover, cytoplasmic and nuclear MUC13 expression correlated with larger and poorly differentiated tumors. Four of six tested colon cancer cell lines also expressed MUC13 at RNA and protein levels. These studies demonstrate a significant increase in MUC13 expression in metastatic colon cancer and suggest a correlation between aberrant MUC13 localization (cytoplasmic and nuclear expression) and metastatic colon cancer.

    Prognostic factors for survival after liver resection for metastatic colorectal cancer identified up to date are quite inconsistent with a great inter-study variability. In this study we aimed to identify predictors of outcome in our patient population. A series of 70 consecutive patients from the oncological hepatobiliary database, who had undergone curative hepatic surgical resection for hepatic metastases of colorectal origin, operated between 2006 and 2011, were identified. At 44.6 months (range 13.7-73), 30 of 70 patients (42.85%) were alive. Patient demographics, primary tumor and liver tumor factors, operative factors, pathologic findings, recurrence patterns, disease-free survival (DFS), overall survival (OS) and cancer-specific survival (CSS) were analyzed. Clinicopathologic variables were tested using univariate and multivariate analyses. The 3-year CSS after first hepatic resection was 54%. Median CSS survival after first hepatic resection was 40.2 months. Median CSS after second hepatic resection was 24.2 months. The 3-year DFS after first hepatic resection was 14%. Median disease free survival after first hepatic resection was 18 months. The 3-year DFS after second hepatic resection was 27% and median DFS after second hepatic resection 12 months. The 30-day mortality and morbidity rate after first hepatic resection was 5.71% and 12.78%, respectively. In univariate analysis CSS was significantly reduced for the following factors: age >53 years, advanced T stage of primary tumor, moderately- poorly differentiated tumor, positive and narrow resection margin, preoperative CEA level >30 ng/ml, DFS <18 months. Perioperative chemotherapy related to metastasectomy showed a trend in improving CSS (p=0.07). Perioperative chemotherapy improved DFS in a statistically significant way (p=0.03). Perioperative chemotherapy and achievement of resection margins beyond 1 mm were the major determinants of both CSS and DFS after first liver resection in multivariate

    In the last decade, there have been multiple landmark therapeutic advances for the treatment of metastatic prostate cancer, both in the castration-resistant and hormone-sensitive setting. In this review, we highlight recent progress and ongoing trials for metastatic prostate cancer, including advances in chemotherapy, androgen receptor-directed therapy, targeted therapies, and immunotherapy. Several landmark studies for men with metastatic hormone-sensitive prostate cancer demonstrated improvement in overall survival with the addition of docetaxel chemotherapy or abiraterone acetate to standard androgen deprivation therapy. A single-arm phase 2 study of the PARP inhibitor olaparib demonstrated high response rates and more favorable progression-free and overall survival for men with metastatic castration-resistant prostate cancer and DNA repair defects treated with olaparib compared with men without DNA repair defects. Multiple ongoing clinical trials are investigating novel hormonal therapies and combinations of chemotherapy, targeted small molecules, immunotherapy, and radiopharmaceuticals. Progress continues to be made in the treatment of metastatic prostate cancer, and ongoing clinical trials continue to investigate novel agents and approaches to treatment.

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

  16. Metastatic Organotropism: An Intrinsic Property of Breast Cancer Molecular Subtypes.

    Science.gov (United States)

    Wei, Shi; Siegal, Gene P

    2017-03-01

    It has long been known that some cancers have the propensity to metastasize to certain organs thus creating a nonrandom distribution of sites for distant relapse, a phenomenon known as "metastatic organotropism." Some of these examples include ovary primary to abdominal cavity, prostate primary to bone, and pancreas primary to liver. In contrast, other tumor types, such as mammary and renal cell carcinoma, can relapse in multiple organs although approximately half of advanced breast cancers metastasize to bone. On the other hand gene expression profiling studies have identified various breast cancer classes with prognostic significance. Recent studies have revealed that breast cancer subtypes differ not only in primary tumor characteristics but also in their metastatic behavior. In particular, the luminal tumors are remarkable for their significant bone-seeking phenotype; the HER2 subtype demonstrates a significant liver-homing characteristic; whereas so-called triple-negative breast cancers predispose to lung metastases. These findings suggest that this knowledge could potentially be utilized in the development of effective disease surveillance strategies in the pursuit of precision medicine, thus necessitating further investigation.

    2003-01-01

    Purpose:To quantify liver metastases and future remnant liver (FRL) volumes in patients who underwent right portal vein embolization (RPVE) and to evaluate the effects of this procedure on metastase growth. Material and Methods:Nine patients with liver metastases from primary colon (n = 5), rectal lesions (n = 1) and carcinoid tumors (n = 3) underwent spiral CT to evaluate the ratio of the non-tumorous parenchymal volume of the resected liver to that of the whole liver volume (R2). Hand tracing was used to isolate the entire liver, the resected liver and metastase volumes. All patients with R2 > 60% underwent RPVE. Results:FRL exhibited a 101-336 cm3 (average 241 cm3) increase in volume 1 month after RPVE. One patient refused surgery for 2 months and before surgery the increase in volume of the FRL was similar to that of other patients (180.64 cm3). Percent metastases volume from colorectal carcinoma in embolized liver parenchyma increased from 62.4% to 138.4% at 1 month and to 562% at 2 months after RPVE. Metastase volume from carcinoid tumors was unchanged. Conclusion:One month after RPVE, hypertrophy of the FRL is evident. In the embolized liver, there was a progressive increase in metastase volume from colorectal carcinoma while metastase volume from carcinoid tumor was unchanged in embolized and non-embolized liver

    2013-01-01

    Metastatic castrate resistant prostate cancer (CRPC) is a leading cause of cancer mortality among men in western countries. Although nearly 85% of patients present with localised disease, up to 40% will eventually develop metastatic disease during the course of illness. Of men dying from prostate cancer, more than 90% have bone metastases many with no other significant metastatic sites. Symptoms related to bone metastases and skeletal related events (SREs) account for the major cause of morbidity in these patients. Bone-seeking radionuclides have been used in the treatment of prostate cancer bone metastases for many years. The first bone seeking radionuclide drug approved by the FDA was Strontium-89. Other agents have also been used including Samarium-153 EDTMP, Rhenium-186 (-188)-HEDP. These radionuclides are all emit shortrange therapeutic beta radiation with bone marrow as the dose limiting toxicity. There is strong clinical trial evidence of benefit for these radionuclides in reducing pain in advanced prostate cancer; however, none of the drugs has been shown to improve survival, albeit none of the clinical trials were powered to detect differences in survival

  6. Disseminated breast cancer cells acquire a highly malignant and aggressive metastatic phenotype during metastatic latency in the bone.

    Directory of Open Access Journals (Sweden)

    Carolyn G Marsden

    Full Text Available BACKGROUND: Disseminated tumor cells (DTCs in the bone marrow may exist in a dormant state for extended periods of time, maintaining the ability to proliferate upon activation, engraft at new sites, and form detectable metastases. However, understanding of the behavior and biology of dormant breast cancer cells in the bone marrow niche remains limited, as well as their potential involvement in tumor recurrence and metastasis. Therefore, the purpose of this study was to investigate the tumorigenicity and metastatic potential of dormant disseminated breast cancer cells (prior to activation in the bone marrow. METHODOLOGY/PRINCIPAL FINDINGS: Total bone marrow, isolated from mice previously injected with tumorspheres into the mammary fat pad, was injected into the mammary fat pad of NUDE mice. As a negative control, bone marrow isolated from non-injected mice was injected into the mammary fat pad of NUDE mice. The resultant tumors were analyzed by immunohistochemistry for expression of epithelial and mesenchymal markers. Mouse lungs, livers, and kidneys were analyzed by H+E staining to detect metastases. The injection of bone marrow isolated from mice previously injected with tumorspheres into the mammary fat pad, resulted in large tumor formation in the mammary fat pad 2 months post-injection. However, the injection of bone marrow isolated from non-injected mice did not result in tumor formation in the mammary fat pad. The DTC-derived tumors exhibited accelerated development of metastatic lesions within the lung, liver and kidney. The resultant tumors and the majority of metastatic lesions within the lung and liver exhibited a mesenchymal-like phenotype. CONCLUSIONS/SIGNIFICANCE: Dormant DTCs within the bone marrow are highly malignant upon injection into the mammary fat pad, with the accelerated development of metastatic lesions within the lung, liver and kidney. These results suggest the acquisition of a more aggressive phenotype of DTCs during

    2018-06-01

    Full Text Available In a patient with a medical history of cancer, the most probable diagnosis of an 18FDG-avid pulmonary mass combined with intracranial abnormalities on brain imaging is metastasized cancer. However, sometimes a differential diagnosis with an infectious cause such as aspergillosis can be very challenging as both cancer and infection are sometimes difficult to distinguish. Pulmonary aspergillosis can present as an infectious pseudotumour with clinical and imaging characteristics mimicking lung cancer. Even in the presence of cerebral lesions, radiological appearance of abscesses can look like brain metastasis. These similarities can cause significant diagnostic difficulties with a subsequent therapeutic delay and a potential adverse outcome. Awareness of this infectious disease that can mimic lung cancer, even in an immunocompetent patient, is important. We report a case of a 65-year-old woman with pulmonary aspergillosis disseminated to the brain mimicking metastatic lung cancer.

    2016-01-01

    Full Text Available Introduction: Prostate cancer remains a challenge as a target for immunological approaches. The approval of the first cell-based immune therapy, Sipuleucel-T for prostate cancer introduced prostate cancer as a solid tumor with the potential to be influenced by the immune system. Methods: We reviewed articles on immunological management of prostate cancer and challenges that lie ahead for such strategies. Results: Treatments have focused on the identification of novel cell surface antigens thought to be unique to prostate cancer. These include vaccines against carbohydrate and blood group antigens, xenogeneic and naked DNA vaccines, and pox viruses used as prime-boost or checkpoint inhibitors. No single vaccine construct to date has resulted in a dramatic antitumor effect. The checkpoint inhibitor, anti-CTLA-4 has resulted in several long-term remissions, but phase III trials have not demonstrated an antitumor effect or survival benefit. Conclusions: Multiple clinical trials suggest that prostate cancer may not be optimally treated by single agent immune therapies and that combination with biologic agents, chemotherapies, or radiation may offer some enhancement of benefit.

    2013-01-01

    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

    Full Text Available Tissue perfusion plays a critical role in oncology because growth and migration of cancerous cells require proliferation of new blood vessels through the process of tumor angiogenesis. Computed tomography (CT perfusion is an emerging functional imaging modality that measures tissue perfusion through dynamic CT scanning following intravenous administration of contrast medium. This noninvasive technique provides a quantitative basis for assessing tumor angiogenesis. CT perfusion has been utilized on a variety of organs including lung, prostate, liver, and brain, with promising results in cancer diagnosis, disease prognostication, prediction, and treatment monitoring. In this paper, we focus on assessing the extent to which CT perfusion characteristics can be used to discriminate liver metastases from neuroendocrine tumors from normal liver tissues. The neuroendocrine liver metastases were analyzed by distributed parameter modeling to yield tissue blood flow (BF, blood volume (BV, mean transit time (MTT, permeability (PS, and hepatic arterial fraction (HAF, for tumor and normal liver. The result reveals the potential of CT perfusion as a tool for constructing biomarkers from features of the hepatic vasculature for guiding cancer detection, prognostication, and treatment selection.

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

    We investigated whether the concept of oligometastasis may be introduced to the clinical management of metastatic bladder cancer patients. Our study population comprised 128 patients diagnosed with metastatic bladder cancer after total cystectomy at our 6 institutions between 2004 and 2014. We extracted independent predictors for identifying a favorable. Occurrence that fulfilled all 4 criteria which were independently associated with cancer-specific death was defined as oligometastasis: a solitary metastatic organ; number of metastatic lesions of 3 or less; the largest diameter of metastatic foci of 5cm or less; and no liver metastasis. We evaluated differences in clinical outcomes between patients with oligometastasis (oligometastasis group) and those without oligometastasis (non-oligometastasis group). Overall, there were 43 patients in the oligometastasis group. The 2-year cancer-specific survival rate in the oligometastasis group was 53.3%, which was significantly higher than that in the non-oligometastasis group (16.1%, poligometastasis (poligometastasis group. The 2-year cancer-specific survival rate in the oligometastasis group was 55.0%, which was significantly higher than that in the non-oligometastasis group (22.0%, p=0.005). Non-oligometastasis (p=0.009) was the only independent risk factor for cancer-specific death. We presented that urothelial carcinoma with oligometastasis had a favorable prognosis and responded to systemic chemotherapy. Oligometastasis may be treated as a separate entity in the field of metastatic urothelial carcinoma.

    PurposeTo evaluate the outcome of patients with melanoma liver metastasis treated with stereotactic radiofrequency ablation (SRFA).Material and MethodFollowing IRB approval, a retrospective evaluation of the treatment of 20 patients with 75 melanoma liver metastases was performed.ResultsA median number of 2 lesions (range 1–14) per patient with a median size of 1.7 cm (range 0.5–14.5 cm) were treated. 67 lesions were <3 cm (89.3 %) and 8 lesions were >3 cm (10.7 %). Per patient a median of 1 ablation session was performed (range: 1–4) totaling 34 sessions. There were no procedure-related deaths and all major complications (n = 3) could be easily treated by pleural drainages. The primary and secondary success rates were 89.3 and 93.3 %, respectively. The overall local recurrence rate was 13.3 %. Four of ten local recurrences were re-treated successfully by SRFA. During follow-up, 9/20 patients developed extrahepatic metastatic disease and 10/20 had liver recurrence at any location. The median OS from the date of SRFA was 19.3 months, with an OS of 64, 41, and 17 % at 1, 3, and 5 years, with no significant difference for patients with cutaneous and ocular melanoma. The median DFS after SRFA for all 20 patients was 9.5 months, with 37, 9, and 0 % at 1, 3, and 5 years.ConclusionsDue to the high local curative potential and the promising long-term survival rates associated with minimal morbidity and mortality, radiofrequency ablation seems to be an attractive alternative to resection in patients with melanoma liver metastases.

    2018-02-01

    Full Text Available SATB2 (Special AT-rich sequence-binding protein 2 has recently been shown to be a specific biomarker of colorectal cancer (CRC. The aim of this study was to investigate the diagnostic potential of SATB2 as a means of detecting a CRC origin for liver metastases. SATB2 expression was examined in a resection cohort of 101 CRC and 273 non-CRC adenocarcinoma samples using immunohistochemistry (IHC. The diagnostic accuracy of CRC origins of liver metastases based on SATB2 and a three marker panel of SATB2, CK20 and CDX2 was evaluated using an independent cohort of 192 liver biopsies. IHC showed 97 of the 101 (96.0% primary CRC samples were SATB2 positive, compared to only 6 of the 273 (2.1% samples of other cancer types. The sensitivity, specificity and AUC values of SATB2 expression in resection samples were 97%, 97.1% and 0.977, respectively. Meanwhile, for the liver biopsy samples, the sensitivity, specificity and AUC values of a CRC liver metastases was 92.2%, 97.8% and 0.948 for SATB2, 95.1%, 91.0% and 0.959 for CK20, and 100%, 85.4% and 0.976 for CDX2, respectively. Further analysis demonstrated that all three-marker positivity was detected in 92/103 (89.3% CRC and 2/89 (2.2% non-CRC liver metastases sampled by biopsy. Our findings suggest that SATB2, as measured by IHC, could serve as a promising diagnostic biomarker of CRC metastases. Combining evaluation of SATB2 with CK20 and CDX2 to form a three marker panel further improved the detection of metastatic CRCs in liver biopsy tissues.

    Transhepatic radionuclide infusion has been introduced as a new treatment approach for unresectable liver neuroendocrine metastatic lesions with the prerequisite of a positive In-111 Pentetreotide (Octreoscan). Patients with multiple liver neuroendocrine metastases can be locally treated after selective hepatic artery catheterization and infusion of radiolabeled somatostatin analogs, and in case of extra-hepatic secondary spread, after simple i.v. application. According to the world wide references, the average dose per session to each patient is 6.3 ± 0.3 GBq (∼160–180 mCi) of In-111-DTPA-Phe1-Pentetreotide, 10- to 12-fold in total, administered monthly or of 4.1 ± 0.2 GBq (∼105–116 mCi) of Y-90 DOTA TOC, threefold in total, or of 7.0 ± 0.4 GBq (∼178–200 mCi) of Lu-177 DOTA TATE, fourfold to sixfold in total (the choice of which being based on the tumor size, assessed by CT or MRI). Follow-up at monthly intervals has to be performed by means of ultrasonography (US). Treatment response has to be assessed according to the WHO criteria (RECIST or SWOG).

    Full Text Available The transmembrane receptor guanylate cyclase-C (GCC has been found to be expressed in colorectal cancers. However, limited data are available on GCC protein expression in non-colorectal gastrointestinal tumors and few studies have reported whether GCC protein expression was consistently preserved in synchronous primary and metastatic cancer tissues.GCC protein status was assessed by immunohistochemistry in tumor specimens from individuals (n = 627 with gastrointestinal tumors, including esophageal (n = 130, gastric (n = 276, pancreatic (n = 136, and colorectal (n = 85 primary and metastatic tumors. Tissue specimens consisted of tissue microarrays containing esophageal, gastric, pancreatic tumors, and whole-slide tissue sections from colorectal cancer patients with matching primary and metastatic tumors.Among the evaluated esophageal, gastric, and pancreatic tumors, the frequency of GCC positivity at the protein level ranged from 59% to 68%. GCC was consistently expressed in primary and matched/synchronous metastatic lesions of colorectal cancer tissues derived from the same patients.This observational study demonstrated the protein expression of GCC across various gastrointestinal malignancies. In all cancer histotypes, GCC protein localization was observed predominantly in the cytoplasm compared to the membrane region of tumor cells. Consistent immunohistochemistry detection of GCC protein expression in primary colorectal cancers and in their matched liver metastases suggests that the expression of GCC is maintained throughout the process of tumor progression and formation of metastatic disease.

    Full Text Available Ying-dong Cheng, Hua Yang, Guo-qing Chen, Zhi-cao Zhang Department of General Surgery, Xinqiao Hospital, Third Military Medical University, Chongqing, People's Republic of China Abstract: The survival rate of patients with metastatic colorectal cancer (mCRC has significantly improved with applications of molecularly targeted drugs, such as bevacizumab, and led to a substantial improvement in the overall survival rate. These drugs are capable of specifically targeting the inherent abnormal pathways in cancer cells, which are potentially less toxic than traditional nonselective chemotherapeutics. In this review, the recent clinical information about molecularly targeted therapy for mCRC is summarized, with specific focus on several of the US Food and Drug Administration-approved molecularly targeted drugs for the treatment of mCRC in the clinic. Progression-free and overall survival in patients with mCRC was improved greatly by the addition of bevacizumab and/or cetuximab to standard chemotherapy, in either first- or second-line treatment. Aflibercept has been used in combination with folinic acid (leucovorin–fluorouracil–irinotecan (FOLFIRI chemotherapy in mCRC patients and among patients with mCRC with wild-type KRAS, the outcomes were significantly improved by panitumumab in combination with folinic acid (leucovorin–fluorouracil–oxaliplatin (FOLFOX or FOLFIRI. Because of the new preliminary studies, it has been recommended that regorafenib be used with FOLFOX or FOLFIRI as first- or second-line treatment of mCRC chemotherapy. In summary, an era of new opportunities has been opened for treatment of mCRC and/or other malignancies, resulting from the discovery of new selective targeting drugs.

    Prognosis of Her2-positive breast cancer has changed since the introduction of trastuzumab for treatment in metastatic and early breast cancer. It was described to be even better compared to prognosis of Her2-negative metastatic breast cancer. The purpose of this study was to evaluate the effect of trastuzumab in our cohort. Besides the effect of adjuvant pretreatment with trastuzumab on survival of patients with metastatic Her2-positive breast cancer was analyzed. All patients with primary breast cancer of the Regional Breast Cancer Center Dresden diagnosed during the years 2001-2013 were analyzed for treatment with or without trastuzumab in the adjuvant and in the metastatic treatment setting using Kaplan-Meier survival estimation and Cox regression. Age and tumor stage at time of first diagnosis of breast cancer as well as hormone receptor status, grading, time, and site of metastasis at first diagnosis of distant metastatic disease were analyzed. Of 4.481 female patients with primary breast cancer, 643 presented with metastatic disease. Her2-positive status was documented in 465 patients, including 116 patients with primary or secondary metastases. Median survival of patients with Her2-positive primary metastatic disease was 3.0 years (95% CI 2.3-4.0). After adjustment for other factors, survival was better in patients with Her2-positive breast cancer with trastuzumab therapy compared to Her2-negative metastatic disease (HR 2.10; 95% CI 1.58-2.79). Analysis of influence of adjuvant therapy with and without trastuzumab by Kaplan-Meier showed a trend for better survival in not pretreated patients. Median survival was highest in hormone receptor-positive Her2-positive (triple-positive) primary metastatic breast cancer patients with 3.3 years (95% CI 2.3-4.6). Prognosis of patients with Her2-positive metastatic breast cancer after trastuzumab treatment is more favorable than for Her2-negative breast cancer.

    Approximately 4-25% of patients with early prostate cancer develop disease recurrence following radical prostatectomy. To identify a molecular subgroup of prostate cancers with metastatic potential at presentation resulting in a high risk of recurrence following radical prostatectomy. Unsupervised hierarchical clustering was performed using gene expression data from 70 primary resections, 31 metastatic lymph nodes, and 25 normal prostate samples. Independent assay validation was performed using 322 radical prostatectomy samples from four sites with a mean follow-up of 50.3 months. Molecular subgroups were identified using unsupervised hierarchical clustering. A partial least squares approach was used to generate a gene expression assay. Relationships with outcome (time to biochemical and metastatic recurrence) were analysed using multivariable Cox regression and log-rank analysis. A molecular subgroup of primary prostate cancer with biology similar to metastatic disease was identified. A 70-transcript signature (metastatic assay) was developed and independently validated in the radical prostatectomy samples. Metastatic assay positive patients had increased risk of biochemical recurrence (multivariable hazard ratio [HR] 1.62 [1.13-2.33]; p=0.0092) and metastatic recurrence (multivariable HR=3.20 [1.76-5.80]; p=0.0001). A combined model with Cancer of the Prostate Risk Assessment post surgical (CAPRA-S) identified patients at an increased risk of biochemical and metastatic recurrence superior to either model alone (HR=2.67 [1.90-3.75]; pmolecular subgroup of primary prostate cancers with metastatic potential. The metastatic assay may improve the ability to detect patients at risk of metastatic recurrence following radical prostatectomy.

    Colon cancer frequently results in metastasis to the liver, where it becomes the main cause of death. However, the cell cycle in primary tumors and metastases is poorly understood. We developed a mouse model of liver metastasis using the human colon cancer cell line HCT-116, which expresses green fluorescent protein (GFP) in the nucleus and red fluorescent protein (RFP) in the cytoplasm (HCT-116-GFP-RFP). HCT-116 GFP-RFP cells were injected into the spleen of nu/nu nude mice. HCT-116-GFP-RFP cells subsequently formed primary tumors in the spleen, as well as metastatic colonies in the liver and retroperitoneum by 28 days after cell transplantation. Using an Olympus FV1000 confocal microscope, it was possible to clearly image mitosis of the dual-colored colon cancer cells in the primary tumor as well as liver and other metastases. Multi-nucleate cancer cells, in addition to mono-nucleate cancer cells and their mitosis, were observed in the primary tumor and metastasis. Multi-nucleate HCT-116-GFP-RFP cells were also observed after culture of the primary and metastatic tumors. A similar ratio of mono-nucleate, multi-nucleate, and mitotic cells grew from the primary and metastatic tumors in culture, suggesting similarity of the nuclear-cytoplasmic dynamics of primary and metastatic cancer cells, further emphasizing the stochastic nature of metastasis. Our results demonstrate a similar heterogeneity of nuclear-cytoplasmic dynamics within primary tumors and metastases, which may be an important factor in the stochastic nature of metastasis.

    Recently, vascular endothelial growth factor receptor (VEGFR)-targeted tyrosine kinase inhibitors (TKIs) have become available for the treatment of recurrent or metastatic thyroid cancer. However, a number of clinical challenges that impact the use of VEGFR-targeted TKI in daily clinical practice have arisen. Toxicity is considerable, to the extent that most physicians hesitate to start VEGFR-targeted TKI and prefer to continue a watch-and-wait approach until the patient's disease markedly worsens. This delayed use of VEGFR-targeted TKI leads to a higher incidence of serious adverse events than was reported in clinical trials. Moreover, the watch-and-wait approach has several demerits, including a worsening of quality of life, worsening of outcomes in patients of older age or with follicular thyroid cancer and increased risk of brain metastasis or bleeding. Thus, optimal timing for the start of VEGFR-targeted TKI requires careful consideration. Moreover, management of VEGFR-targeted TKI toxicities requires appropriate supportive care, well-organised infrastructure in the outpatient clinic and patient education. Future treatment will progress to precision medicine based on molecular testing. Promotion of precision medicine requires the establishment of a system of easy access to molecular testing and the promotion of translational research for the development of new drugs.

    Patients with advanced colorectal cancer have a high incidence of postoperative complications. We sought to identify outcomes of patients who underwent resection for colon cancer by cancer stage. The National Surgical Quality Improvement Program database was used to evaluate all patients who underwent colon resection with a diagnosis of colon cancer from 2012 to 2014. Multivariate logistic regression analysis was performed to investigate patient outcomes by cancer stage. A total of 7,786 colon cancer patients who underwent colon resection were identified. Of these, 10.8% had metastasis at the time of operation. Patients with metastatic disease had significantly increased risks of perioperative morbidity (adjusted odds ratio [AOR]: 1.44, P = .01) and mortality (AOR: 3.72, P = .01). Patients with metastatic disease were significantly younger (AOR: .99, P colon cancer have metastatic disease. Postoperative morbidity and mortality are significantly higher than in patients with localized disease. Published by Elsevier Inc.

    Full Text Available Breast cancer metastases to the stomach are very rare. As characteristics of breast cancer metastases to the stomach, metastases of lobular carcinoma, mainly with signet ring cells, are frequently observed, and they are often difficult to distinguish from a primary gastric cancer with signet ring cells. Moreover, because no characteristic symptoms are shown and they involve a submucosal lesion, it is difficult to make a radiographic diagnosis. However, if a gastric lesion is observed after breast carcinoma surgery, differentiation between a gastric primary lesion and a metastatic lesion is very important in order to determine treatment. We encountered a case that was diagnosed as early gastric cancer discovered using an endoscope 2 years after surgery and which was found to be breast cancer metastasis to the stomach by gross cystic disease fluid protein (GCDFP and cytokeratin (CK 7/20 immunostaining of the biopsy tissue. Here, we report our findings of this unique case.

    Metastatic adrenocortical carcinoma (ACC) is rapidly fatal, with few options for treatment. Patients with metachronous recurrence may benefit from surgical resection. The survival benefit in patients with hematogenous metastasis at initial presentation is unknown. A review of all patients undergoing surgery (European Network for the Study of Adrenal Tumors) stage IV ACC between January 2000 and December 2012 from two referral centers was performed. Kaplan-Meier estimates were analyzed for disease-free and overall survival (OS). We identified 27 patients undergoing surgery for stage IV ACC. Metastases were present in the lung (19), liver (11), and brain (1). A complete resection (R0) was achieved in 11 patients. The median OS was improved in patients undergoing R0 versus R2 resection (860 vs. 390 days; p = 0.02). The 1- and 2-year OS was also improved in patients undergoing R0 versus R2 resection (69.9 %, 46.9 % vs. 53.0 %, 22.1 %; p = 0.02). Patients undergoing neoadjuvant therapy (eight patients) had a trend towards improved survival at 1, 2, and 5 years versus no neoadjuvant therapy (18 patients) [83.3 %, 62.5 %, 41.7 % vs. 56.8 %, 26.6 %, 8.9 %; p = 0.1]. Adjuvant therapy was associated with improved recurrence-free survival at 6 months and 1 year (67 %, 33 % vs. 40 %, 20 %; p = 0.04) but not improved OS (p = 0.63). Sex (p = 0.13), age (p = 0.95), and location of metastasis (lung, p = 0.51; liver, p = 0.67) did not correlate with OS after operative intervention. Symptoms of hormonal excess improved in 86 % of patients. Operative intervention, especially when an R0 resection can be achieved, following systemic therapy may improve outcomes, including OS, in select patients with stage IV ACC. Response to neoadjuvant chemotherapy may be of use in defining which patients may benefit from surgical intervention. Adjuvant therapy was associated with decreased recurrence but did not improve OS.

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

    Highlights: • Colorectal cancer is the third most prevalent cancer and the status of the regional lymph nodes in rectal cancer is considered to be one of the most powerful prognostic factor in the absence of distant metastatic disease. Detecting LNs metastasis is still a challenging problem due to the presence of microscopic metastasis or inflammatory swelling of LNs. • We investigated the value of dual energy spectral CT in differentiating metastatic from non-metastatic lymph nodes in rectal cancer. Our study demonstrated that the quantitative normalized iodine concentration (nIC) could be useful for differentiating metastatic and non-metastatic lymph nodes. The combination of nIC in portal venous phase and conventional size criterion could improve the diagnostic accuracy, sensitivity, specificity, positive predictive value and negative predictive value of rectal cancer. - Abstract: Objectives: To investigate the value of dual energy spectral CT (DEsCT) imaging in differentiating metastatic from non-metastatic lymph nodes in rectal cancer. Methods: Fifty-five patients with rectal cancer underwent the arterial phase (AP) and portal venous phase (PP) contrast-enhanced DEsCT imaging. The virtual monochromatic images and iodine-based material decomposition images derived from DEsCT imaging were interpreted for lymph nodes (LNs) measurement. The short axis diameter and the normalized iodine concentration (nIC) of metastatic and non-metastatic LNs were measured. The two-sample t test was used to compare the short axis diameters and nIC values of metastatic and non-metastatic LNs. ROC analysis was performed to assess the diagnostic performance. Results: One hundred and fifty two LNs including 92 non-metastatic LNs and 60 metastatic LNs were matched using the radiological-pathological correlation. The mean short axis diameter of metastatic LNs was significantly larger than that of the non-metastatic LNs (7.28 ± 2.28 mm vs. 4.90 ± 1.64 mm, P < 0.001). The mean n

  4. Liver cancer and selective internal radiation therapy

    Liver cancer is the biggest cancer-related killer of adults in the world. Liver cancer can be considered as two types: primary and secondary (metastatic). Selective Internal Radiation Therapy (SIRT) is a revolutionary treatment for advanced liver cancer that utilises new technologies designed to deliver radiation directly to the site of tumours. SIRT, on the other hand, involves the delivery of millions of microscopic radioactive spheres called SIR-Spheres directly to the site of the liver tumour/s, where they selectively irradiate the tumours. The anti-cancer effect is concentrated in the liver and there is little effect on cancer at other sites such as the lungs or bones. The SIR-Spheres are delivered through a catheter placed in the femoral artery of the upper thigh and threaded through the hepatic artery (the major blood vessel of the liver) to the site of the tumour. The microscopic spheres, each approximately 35 microns (the size of four red blood cells or one-third the diameter of a strand of hair), are bonded to yttrium-90 (Y-90), a pure beta emitter with a physical half-life of 64.1 hours (about 2.67 days). The microspheres are trapped in the tumour's vascular bed, where they destroy the tumour from inside. The average range of the radiation is only 2.5 mm, so it is wholly contained within the patient's body; after 14 days, only 2.5 percent of the radioactive activity remains. The microspheres are suspended in water for injection. The vials are shipped in lead shields for radiation protection. Treatment with SIR-Spheres is generally not regarded as a cure, but has been shown to shrink the cancer more than chemotherapy alone. This can increase life expectancy and improve quality of life. On occasion, patients treated with SIR-Spheres have had such marked shrinkage of the liver cancer that the cancer can be surgically removed at a later date. This has resulted in a long-term cure for some patients. SIRTeX Medical Limited has developed three separate cancer

    Full Text Available Shannon Puhalla, Adam BrufskyUPMC Magee-Womens Cancer Program, University of Pittsburgh, Pittsburgh, Pennsylvania, USAAbstract: Taxane therapy is commonly used in the treatment of metastatic breast cancer. However, most patients will eventually become refractory to these agents. Ixabepilone is a newly approved chemotherapeutic agent for the treatment of metastatic breast cancer. Although it targets microtubules similarly to docetaxel and paclitaxel, ixabepilone has activity in patients that are refractory to taxanes. This review summarizes the pharmacology of ixapebilone and clinical trials with the drug both as a single agent and in combination. Data were obtained using searches of PubMed and abstracts of the annual meetings of the American Society of Clinical Oncology and the San Antonio Breast Cancer Symposium from 1995 to 2008. Ixapebilone is a semi-synthetic analog of epothilone B that acts to induce apoptosis of cancer cells via the stabilization of microtubules. Phase I clinical trials have employed various dosing schedules ranging from daily to weekly to 3-weekly. Dose-limiting toxicites included neuropathy and neutropenia. Responses were seen in a variety of tumor types. Phase II studies verified activity in taxane-refractory metastatic breast cancer. The FDA has approved ixabepilone for use as monotherapy and in combination with capecitabine for the treatment of metastatic breast cancer. Ixabepilone is an efficacious option for patients with refractory metastatic breast cancer. The safety profile is similar to that of taxanes, with neuropathy and neutropenia being dose-limiting. Studies are ongoing with the use of both iv and oral formulations and in combination with other chemotherapeutic and biologic agents.Keywords: ixabepilone, epothilone, metastatic breast cancer, taxane-refractory

    Accurate methods for determining metastatic risk from the primary tumor are crucial for patient survival. Cell metabolism could potentially be used as a marker of metastatic risk. Optical imaging of the endogenous fluorescent molecules nicotinamide adenine dinucleotide (NADH) and flavin adenine dinucleotide (FAD) provides a non-destructive and label-free method for determining cell metabolism. The optical redox ratio (FAD/FAD+NADH) is sensitive to the balance between glycolysis and oxidative phosphorylation (OXPHOS). We have previously established that hypoxia-reoxygenation stress leads to metastatic potential-dependent changes in optical redox ratio. The objective of this study was to monitor the changes in optical redox ratio in breast cancer cells in response to different periods of hypoxic stress as well various levels of hypoxia to establish an optimal protocol. We measured the optical redox ratio of highly metastatic 4T1 murine breast cancer cells under normoxic conditions and after exposure to 30, 60, and 120 minutes of 0.5% O2. This was followed by an hour of reoxygenation. We found an increase in the optical redox ratio following reoxygenation from hypoxia for all durations. Statistically significant differences were observed at 60 and 120 minutes (p˂0.01) compared with normoxia, implying an ability to adapt to OXPHOS after reoxygenation. The switch to OXPHOS has been shown to be a key promoter of cell invasion. We will present our results from these investigations in human breast cancer cells as well as non-metastatic breast cancer cells exposed to various levels of hypoxia.

    Purpose: Stereotactic body radiation therapy (SBRT) provides a high local control rate for primary and metastatic liver tumors. The aim of this study is to assess the impact of this treatment on the patient's quality of life. This is the first report of quality of life associated with liver SBRT. Methods and Materials: From October 2002 to March 2007, a total of 28 patients not suitable for other local treatments and with Karnofsky performance status of at least 80% were entered in a Phase I-II study of SBRT for liver tumors. Quality of life was a secondary end point. Two generic quality of life instruments were investigated, EuroQol-5D (EQ-5D) and EuroQoL-Visual Analogue Scale (EQ-5D VAS), in addition to a disease-specific questionnaire, the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ C-30). Points of measurement were directly before and 1, 3, and 6 months after treatment. Mean scores and SDs were calculated. Statistical analysis was performed using paired-samples t-test and Student t-test. Results: The calculated EQ-5D index, EQ-5D VAS and QLQ C-30 global health status showed that mean quality of life of the patient group was not significantly influenced by treatment with SBRT; if anything, a tendency toward improvement was found. Conclusions: Stereotactic body radiation therapy combines a high local control rate, by delivering a high dose per fraction, with no significant change in quality of life. Multicenter studies including larger numbers of patients are recommended and under development

    Purpose: Evaluation of the sensitivity and specificity of glypican3 (GPC3) in differentiating hepatocellular carcinoma (HCC) from metastatic carcinomas of the liver in cell block material. Patients and methods: Sixty cell blocks were prepared from liver FNAs performed in the radiodiagnosis department, National Cancer Institute, in the period between August 2011 and May 2012. Cases diagnosed as hepatocellular carcinoma, or metastatic carcinoma were included in the study. Cell block sections were stained with anti GPC-3. Sensitivity, specificity, and positive and negative predictive values, of GPC3 were calculated. The final diagnosis was based on the triple approach of clinical data, radiological findings, as well as cytomorphologic features aided by GPC-3 results. Results: 70% of cases were diagnosed as HCC, and 30% as metastatic carcinomas. 95.2% of HCC cases expressed GPC3. Poorly differentiated cases showed the highest GPC3 sensitivity (100%), followed by moderately differentiated cases (96.5%), while well differentiated cases expressed GPC3 in 90% of cases. 83.3% of metastatic carcinomas were negative for GPC3. In this study, sensitivity of GPC-3 in HCC was 95.2%, specificity was 83.3%, positive and negative predictive values were 93% and 88.2% respectively, and total accuracy was 91.7%. Conclusion: Immunocytochemical staining for GPC3 in cell block material is a highly sensitive and specific method capable of distinguishing HCC from the vast majority of metastatic carcinomas of the liver

    Objective To review and evaluate current literature on the US Food and Drug Administration (FDA)-approved drug enzalutamide (XTANDI®) in metastatic castration-resistant prostate cancer. Data sources Literature search was done through PubMed using the terms enzalutamide, MDV3100, abiraterone, and castration-resistant prostate cancer. Data from FDA product labels were also used. Study selection and data extraction Recent and relevant studies were included in the review. Collected clinical trials were screened and evaluated. Data synthesis Enzalutamide is an androgen receptor (AR) inhibitor with high selectivity and affinity to the AR. It was approved by the FDA to treat metastatic castration-resistant prostate cancer in patients previously treated with docetaxel, after a Phase III trial (AFFIRM) that showed a 4.8-month survival benefit in this population. Recently, the FDA expanded the approval of enzalutamide as first-line therapy for metastatic castration-resistant prostate cancer (mCRPC) who did not receive chemotherapy. Moreover, enzalutamide is shown to be associated with an acceptable safety profile. Conclusion Enzalutamide has been shown to be both safe and effective in improving overall survival in metastatic castration-resistant prostate cancer postchemotherapy with docetaxel and as a first line treatment before initiation of chemotherapy. However, additional studies and head-to-head trials are needed. PMID:25945058

    A large majority of patients diagnosed with pancreatic cancer have advanced metastatic disease with unresectable malignancies. Despite treatment advances, the survival benefit from chemotherapeutic regimens and targeted drugs is limited. Moreover, their application is limited in China because of high toxicity and cost. Recently, inhibitors of epidermal growth factor receptor activity have shown promise for the treatment of solid cancers when used in combination with standard therapy. However, these drugs have not been evaluated extensively for the treatment of pancreatic cancer. Here, we report the treatment of a 64-year-old male with metastatic pancreatic cancer using a novel regimen of icotinib with gemcitabine. Marked shrinkage of the mass was observed after two treatment cycles, and partial remission was achieved. The abdominal pain was relieved. The adverse effects were tolerable and treatment cost was acceptable. This is the first reported case for the treatment of advanced pancreatic cancer with icotinib plus gemcitabine and demonstrates a promising therapeutic alternative.

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

    Regorafenib is a standard-care option for treatment-refractory metastatic colorectal cancer that increases median overall survival by 6 weeks compared with placebo. Given this small incremental clinical benefit, we evaluated the cost-effectiveness of regorafenib in the third-line setting for patients with metastatic colorectal cancer from the US payer perspective. We developed a Markov model to compare the cost and effectiveness of regorafenib with those of placebo in the third-line treatment of metastatic colorectal cancer. Health outcomes were measured in life-years and quality-adjusted life-years (QALYs). Drug costs were based on Medicare reimbursement rates in 2014. Model robustness was addressed in univariable and probabilistic sensitivity analyses. Regorafenib provided an additional 0.04 QALYs (0.13 life-years) at a cost of $40,000, resulting in an incremental cost-effectiveness ratio of $900,000 per QALY. The incremental cost-effectiveness ratio for regorafenib was > $550,000 per QALY in all of our univariable and probabilistic sensitivity analyses. Regorafenib provides minimal incremental benefit at high incremental cost per QALY in the third-line management of metastatic colorectal cancer. The cost-effectiveness of regorafenib could be improved by the use of value-based pricing. © 2015 by American Society of Clinical Oncology.

  1. Polychlorinated biphenyls (PCBs enhance metastatic properties of breast cancer cells by activating Rho-associated kinase (ROCK.

    Directory of Open Access Journals (Sweden)

    Sijin Liu

    Full Text Available BACKGROUND: Polychlorinated biphenyls (PCBs are a family of structurally related chlorinated aromatic hydrocarbons. Numerous studies have documented a wide spectrum of biological effects of PCBs on human health, such as immunotoxicity, neurotoxicity, estrogenic or antiestrogenic activity, and carcinogenesis. The role of PCBs as etiologic agents for breast cancer has been intensively explored in a variety of in vivo, animal and epidemiologic studies. A number of investigations indicated that higher levels of PCBs in mammary tissues or sera correlated to breast cancer risk, and PCBs might be implicated in advancing breast cancer progression. METHODOLOGY/PRINCIPAL FINDINGS: In the current study, we for the first time report that PCBs greatly promote the ROCK activity and therefore increase cell motility for both non-metastatic and metastatic human breast cancer cells in vitro. In the in vivo study, PCBs significantly advance disease progression, leading to enhanced capability of metastatic breast cancer cells to metastasize to bone, lung and liver. Additionally, PCBs robustly induce the production of intracellular reactive oxygen species (ROS in breast cancer cells; ROS mechanistically elevate ROCK activity. CONCLUSIONS/SIGNIFICANCE: PCBs enhance the metastatic propensity of breast cancer cells by activating the ROCK signaling, which is dependent on ROS induced by PCBs. Inhibition of ROCK may stand for a unique way to restrain metastases in breast cancer upon PCB exposure.

    Full Text Available James J Cody,1 Douglas R Hurst2 1ImQuest BioSciences, Frederick, MD, 2Department of Pathology, University of Alabama at Birmingham, Birmingham, AL, USA Abstract: New therapies for metastatic breast cancer patients are urgently needed. The long-term survival rates remain unacceptably low for patients with recurrent disease or disseminated metastases. In addition, existing therapies often cause a variety of debilitating side effects that severely impact quality of life. Oncolytic viruses constitute a developing therapeutic modality in which interest continues to build due to their ability to spare normal tissue while selectively destroying tumor cells. A number of different viruses have been used to develop oncolytic agents for breast cancer, including herpes simplex virus, adenovirus, vaccinia virus, measles virus, reovirus, and others. In general, clinical trials for several cancers have demonstrated excellent safety records and evidence of efficacy. However, the impressive tumor responses often observed in preclinical studies have yet to be realized in the clinic. In order for the promise of oncolytic virotherapy to be fully realized for breast cancer patients, effectiveness must be demonstrated in metastatic disease. This review provides a summary of oncolytic virotherapy strategies being developed to target metastatic breast cancer. Keywords: oncolytic virus, virotherapy, breast cancer, metastasis

    The aim of this retrospective study was to describe clinical features, treatment and outcome of 21 dogs with metastatic cancer of unknown primary (MCUP), a biopsy-proven malignancy being diagnosed at a metastatic stage, in which the anatomical origin of the primary tumour cannot be detected. All dogs underwent total-body computed tomography. Signalment, type and duration of clinical signs, metastasis site, pathology results, treatment and outcome were recorded. Carcinoma was the most common diagnosis (57.1%), followed by sarcoma, melanoma and mast cell tumour. The median number of disease sites per dog was 2, with bones, lymph nodes, lungs and spleen being the most frequent metastatic locations. The median survival for all dogs was 30 days. Overall, a primary site was not identified in 20 (95.2%) dogs. MCUP encompasses a variety of different pathologic entities and harbours a poor prognosis. © 2013 Blackwell Publishing Ltd.

    Full Text Available The literature review presents the methodology of transarterial chemoembolization (TACE — widely used method of treatment of primary and secondary liver tumors. The TACE role as a neoadjuvant therapy and the role in the management of unresectable primary and secondary liver tumors are shown. The morphofunctional basis of TACE, benefits of superselective intra-arterial administration of cytostatic agents especially in combination with ischemic impact on a tumor are described. The subject of the choice of the chemotherapeutic agent is also touched; modern drug-loaded microspheres which allow the use of higher doses of the chemotherapeutic drug without increasing systemic effect and prolong its effect on tumor are described. Lack of correlation of presence and severity of a post-embolization syndrome with success of the procedure is noted.

    Elevated expression of the inducible heat shock protein 70 (Hsp70) is known to correlate with poor prognosis in many cancers. Hsp70 confers survival advantage as well as resistance to chemotherapeutic agents, and promotes tumor cell invasion. At the same time, tumor-derived extracellular Hsp70 has been recognized as a “chaperokine”, activating antitumor immunity. In this review we discuss localization dependent functions of Hsp70 in the context of invasive cancer. Understanding the molecular principles of metastasis formation steps, as well as interactions of the tumor cells with the microenvironment and the immune system is essential for fighting metastatic cancer. Although Hsp70 has been implicated in different steps of the metastatic process, the exact mechanisms of its action remain to be explored. Known and potential functions of Hsp70 in controlling or modulating of invasion and metastasis are discussed.

It is a novel chemotherapeutic agent currently approved as part of combination chemotherapy for metastatic colorectal cancer, non-small cell lung cancer, and breast cancer (Hurwitz et al 2004; Sandler et al 2006; Traina et al 2007. Arterial thrombosis, including cerebral infarction, transient ischemic attacks, myocardial infarction, and angina are common, occurring in 4.4% of patients whose regimen includes bevacizumab (versus 1.9% on regimen without bevacizumab (Genetech, Inc. 2008. This series will review two cases of patients exposed to bevacizumab who subsequently developed ST elevations on electrocardiogram (ECG and elevated cardiac biomarkers. Both patients underwent cardiac catheterization, which demonstrated apical ballooning and akinesis in a distribution discordant with the observed (noncritical atherosclerotic lesions. Both patients had recovery of left ventricular function within 30 days. The clinical presentation, including ECGs and findings on catheterization as well as the rapid recovery of ventricular function, is consistent with the diagnosis of takotsubo cardiomyopathy. Takotsubo cardiomyopathy was first described in 1991, but the pathophysiology and exact mechanism of injury remain largely unknown. These two cases are notable for their occurrence in men and the association with treatment of metastatic cancer including bevacizumab.Keywords: vascular endothelial growth factor, bevacizumab, metastatic cancer, chemotherapy, takotsubo, cardiomyopathy

    Full Text Available Background Colorectal cancer (CRC is one of the most common malignancies worldwide. Approximately 10%–15% of the CRC cases have defective DNA mismatch repair (MMR genes. Although the high level of microsatellite instability status is a predictor of favorable outcome in primary CRC, little is known about its frequency and importance in secondary CRC. Immunohistochemical staining (IHC for MMR proteins (e.g., MLH1, MSH2, MSH6, and PMS2 has emerged as a useful technique to complement polymerase chain reaction (PCR analyses. Methods In this study, comparison between the MMR system of primary CRCs and paired liver and lung metastatic lesions was done using IHC and the correlation with clinical outcomes was also examined. Results Based on IHC, 7/61 primary tumors (11.4% showed deficient MMR systems, while 13/61 secondary tumors (21.3% showed deficiencies. In total, 44 cases showed proficient expression in both the primary and metastatic lesions. Three cases showed deficiencies in both the primary and paired metastatic lesions. In 10 cases, proficient expression was found only in the primary lesions, and not in the corresponding metastatic lesions. In four cases, proficient expression was detected in the secondary tumor, but not in the primary tumor. Conclusions Although each IHC result and the likely defective genes were not exactly matched between the primary and the metastatic tumors, identical results for primary and metastatic lesions were obtained in 77% of the cases (47/61. These data are in agreement with the previous microsatellite detection studies that used PCR and IHC.

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

    Full Text Available Aim: to analyze qualitative short-time results of a new program for multidisciplinary liver evaluation in complex cases of liver metastasis from colorectal cancer. Patients and methods: 40 clinical consecutive evaluations with liver metastasis assessed for major liver resection by a multidisplinary specialist committee. Complementary explorations performed included CT and ultrasounds, and MRI or PET for doubtful cases. Liver resection was made in a single operation or two-stage hepatectomy, or combined with other techniques. Results: postoperative mortality at 30 days was 4%. Complications occurred in 28%, with surgical wound infection being most frequent (20%; 16.6% of resections were transfused, with a mean volume of 1000 ml. Two patients needed reoperation -one for an intraperitoneal abscess and one for bile-duct stenosis. Percentage of global relapse was 36%, with 26% of relapses out of the liver. Actuarial survival at one year follow-up was 90%, and 82% at two years; 64% of patients remain free of disease two years after the operation. Conclusions: programs for liver resection for colorectal cancer metastasis may be implemented by multidisciplinary teams of recent setup. There is a need to evaluate own results and then compare them with a standard of quality previously reported.Objetivo: valorar los resultados cualitativos a corto y medio plazo de un programa de reciente implantación de evaluación hepática multidisciplinar de casos complejos de metástasis hepáticas de cáncer colorrectal.

    Full Text Available To report the first case of rare isolated breast metastasis from carcinoma gall bladder. Single patient case report. A 35-year-old pre-menopausal female presented with 2 FNx01 2 cm right upper outer quadrant breast lump. Post-mastectomy, histology confirmed it to be metastatic adenocarcinoma positive for both Cytokeratin (CK 7 and CK20. Past history as told by the patient revealed that 2 years back, cholecystectomy was performed for gall stones, of which no histology reports were present; she had a port site scar recurrence which showed it to be adenocarcinoma. Adjuvant chemotherapy and radiotherapy was advised which the patient did not complete. This is probably the first case reported of isolated breast metastasis from gall bladder carcinoma, diagnosed retrospectively. It also highlights the importance of adjuvant treatment in gall bladder malignancy.

    The aim of this study was to determine the prognostic value of quantitative fluorodeoxyglucose (FDG) measurements (maximum standardized uptake value [SUV max ], metabolic tumor volume [MTV], and total lesion glycolysis [TLG]) in patients with newly diagnosed metastatic breast cancer (MBC). An IRB-approved retrospective review was performed of patients who underwent FDG positron emission tomography (PET)/computed tomography (CT) from 1/02 to 12/08 within 60 days of diagnosis MBC. Patients with FDG-avid lesions without receiving chemotherapy in the prior 30 days were included. Target lesions in bone, lymph node (LN), liver, and lung were analyzed for SUV max , MTV, and TLG. Medical records were reviewed for patient characteristics and overall survival (OS). Cox regression was used to test associations between quantitative FDG measurements and OS. A total of 253 patients were identified with disease in bone (n = 150), LN (n = 162), liver (n = 48), and lung (n = 66) at the time of metastatic diagnosis. Higher SUV max tertile was associated with worse OS in bone metastases (highest vs. lowest tertile hazard ratio [HR] = 3.1, P < 0.01), but not in LN, liver or lung (all P > 0.1). Higher MTV tertile was associated with worse OS in LN (HR = 2.4, P < 0.01) and liver (HR = 3.0, P = 0.02) metastases, but not in bone (P = 0.22) or lung (P = 0.14). Higher TLG tertile was associated with worse OS in bone (HR = 2.2, P = 0.02), LN (HR = 2.3, P < 0.01), and liver (HR = 4.9, P < 0.01) metastases, but not in lung (P = 0.19). We conclude measures of FDG avidity are prognostic biomarkers in newly diagnosed MBC. SUV max and TLG were both predictors of survival in breast cancer patients with bone metastases. TLG may be a more informative biomarker of OS than SUV max for patients with LN and liver metastases. Measures of fluorodeoxyglucose (FDG) avidity are prognostic biomarkers in newly diagnosed metastatic breast cancer. Volumetric measurements, such as total lesion glycolysis (TLG

    Neuroendocrine tumors are divided into gastrointestinal carcinoids and pancreatic neuroendocrine tumors. The WHO has updated the classification of these lesions and has abandoned the term "carcinoid". Both types of tumors are divided into functional and non-functional tumors. They are characterized by slow growth and frequent metastasis to the liver and may be limited to the liver for long periods. The therapeutic approach to hepatic metastases should consider the number and distribution of the liver metastases as well as the severity of symptoms related to hormone production and tumor bulk. Surgery is generally considered as the first line therapy. In patients with unresectable liver metastases,alternative treatments are dependent on the type and the growth rate. Initial treatments consist of long acting somatostatin analogs and/or interferon. Streptozocinbased chemotherapy is usually reserved for symptomatic patients with rapidly advancing disease, but generally the therapy is poorly tolerated and its effects are short-lived.Locoregional therapy directed such as hepatic-artery embolization and chemoembolization, radiofrequency thermal ablation and cryosurgery, is often used instead of systemic therapy, if the disease is limited to the liver.However, liver transplantation should be considered in patients with neuroendocrine metastases to the liver that are not accessible to curative or cytoreductive surgery and if medical or locoregional treatment has failed and if there are life threatening hormonal symptoms. We report a case of liver transplantation for metastatic neuroendocrine tumor of unknown primary source and provide a detailed review of the world literature on this controversial topic.

    Full Text Available Brendan Corkery1,2, Norma O’Donovan2, John Crown1,21St. Vincent’s University Hospital, Dublin, Ireland; 2National Institute for Cellular Biotechnology, Dublin City University, Dublin, IrelandAbstract: Improved molecular understanding of breast cancer in recent years has led to the discovery of important drug targets such as HER-2 and EGFR. Lapatinib is a potent dual inhibitor of HER-2 and EGFR. Preclinical and phase I studies have shown activity with lapatinib in a number of cancers, including breast cancer, and the drug is well tolerated. The main known drug interactions are with paclitaxel and irinotecan. The most significant side-effects of lapatinib are diarrhea and adverse skin events. Rates of cardiotoxicity compare favorably with trastuzumab, a monoclonal antibody against HER-2. This paper focuses on lapatinib in advanced and metastatic breast cancer, which remains an important therapeutic challenge. Phase II and III studies show activity as monotherapy, and in combination with chemotherapy or hormonal agents. Results from these studies suggest that the main benefit from lapatinib is in the HER-2 positive breast cancer population. Combinations of lapatinib and trastuzumab are also being studied and show encouraging results, particularly in trastuzumab-refractory metastatic breast cancer. Lapatinib may have a specific role in treating HER-2 positive CNS metastases. The role of lapatinib as neoadjuvant therapy and in early breast cancer is also being evaluated.Keywords: HER-2, EGFR, erbB, lapatinib, Tykerb®, tyrosine kinase

  17. Combination Drug Delivery Approaches in Metastatic Breast Cancer

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Disseminated metastatic breast cancer needs aggressive treatment due to its reduced response to anticancer treatment and hence low survival and quality of life. Although in theory a combination drug therapy has advantages over single-agent therapy, no appreciable survival enhancement is generally reported whereas increased toxicity is frequently seen in combination treatment especially in chemotherapy. Currently used combination treatments in metastatic breast cancer will be discussed with their challenges leading to the introduction of novel combination anticancer drug delivery systems that aim to overcome these challenges. Widely studied drug delivery systems such as liposomes, dendrimers, polymeric nanoparticles, and water-soluble polymers can concurrently carry multiple anticancer drugs in one platform. These carriers can provide improved target specificity achieved by passive and/or active targeting mechanisms.

    2010-01-01

    Full Text Available We report a case of a female with stage I infiltrating ductal carcinoma who received adjuvant therapy including trastuzumab. One year later she developed lytic lesions and was retreated with trastuzumab that was held after she developed symptomatic heart failure. Lytic lesions were attributed to relapse of breast cancer, and cardiac failure attributed to prior trastuzumab therapy. After complications necessitated multiple hospitalizations, a further workup revealed that the lytic lesions were not metastatic breast cancer but multiple myeloma. Her advanced multiple myeloma was associated with systemic amyloidosis involving gut and heart, which ultimately led to her demise. This report addresses the pitfalls of overlapping symptoms and the question of which patients with suspected metastatic disease should undergo a biopsy.

    Waitemata District Health Board has New Zealand's largest catchment and busiest colorectal unit. The upper gastrointestinal unit was established in 2005, in part to provide a hepatic resection service for patients with colorectal carcinoma metastatic to the liver. The aim of this investigation was to report on quality indicators for the hepatic resection of colorectal carcinoma in the development of a regional resection service. Prospectively collected data on patients undergoing hepatic resection for colorectal carcinoma between 2005 and 2014 was reviewed and correlated with costing data and national hepatic resection rates. A total of 123 patients underwent 138 hepatic resections for metastatic colorectal cancer with a median hospital stay of 8 days (range 4-37 days), a zero 30-day mortality and a median cost of NZ$21 374 for minor hepatectomy and NZ$43 133 for major hepatectomy. Actuarial 5-year disease-free survival was 44%, with 28 patients alive and disease free at 5 years post-resection. Median overall survival was not reached. Review of national hepatic resection rates indicate that Waitemata District Health Board performs one sixth of all hepatic resections in New Zealand and that this treatment modality may be underutilized in the management of patients with metastatic colorectal cancer. A regional hepatic resection centre for colorectal metastases can be established in areas of population need and can provide a high-quality, cost-effective service. © 2016 Royal Australasian College of Surgeons.

    Historical anaplastic thyroid cancer (ATC) outcomes have been terrible, with a median survival of only five months and <20% one-year survival. Improved outcomes are now achieved with aggressive initial therapy in stages IVA and IVB disease, but patients with distant metastatic disease (stage IVC) still do poorly; improved therapies are sorely needed. Kinase inhibitors have emerged as promising agents in the therapy of advanced medullary and differentiated thyroid cancer, but there are limited data regarding the use of lenvatinib in ATC. The aim of this study was to delineate clinical outcomes in a series of patients with advanced ATC in response to lenvatinib therapy. A retrospective analysis was conducted involving all lenvatinib-treated Mayo Clinic ATC patients in 2015. Of 28 distinct ATC patients seen in 2015, three (11%) with metastatic disease of ECOG performance status 2-3 were treated with lenvatinib. Two patients were male; age range at ATC diagnosis was 57-84 years. All three patients attained successful local control of their disease with surgery and/or combined chemoradiotherapy. Lenvatinib was offered as the second, third, or fourth line of therapy at the time of metastatic disease progression. Two patients incurred minor responses to therapy, with structural regression of distant metastatic tumor disease soon after starting lenvatinib treatment (at one to two months), while one patient achieved stable disease, but no Response Evaluation Criteria In Solid Tumors partial responses resulted. Overall survival after starting lenvatinib was two, six, and seven months. Fatigue and hypertension were prominent, and one patient developed pulmonary emboli while on lenvatinib. This initial single-institution experience suggests that lenvatinib may have some disease-modifying activity in metastatic ATC that is otherwise refractory to cytotoxic chemotherapy. Unfortunately, observed benefits were transient, and toxicities were prominent. Clinical trials are required

    Chemotherapy has represented the standard therapy for unresectable or metastatic urothelial carcinoma for more than 20 years. The growing knowledge of the interaction between tumour and immune system has led to the advent of new classes of drugs, the immune-checkpoints inhibitors, which are intended to change the current scenario. To date, immunotherapy is able to improve the overall responses and survival. Moreover, thanks to its safety profile immune-checkpoint inhibitors could be proposed also to patients unfit for standard chemotherapy. No doubts that these agents have started a revolution expected for years, but despite this encouraging results it appears clear that not all subjects respond to these agents and requiring the development of reliable predictive response factors able to isolate patients who can more benefit from these treatments as well as new strategies aimed to improve immunotherapy clinical outcome. In this review we describe the active or ongoing clinical trials involving Programmed Death Ligand 1 (PD-L1), Programmed Death receptor 1 (PD-1) and Cytotoxic-T Lymphocyte Antigen 4 (CTLA 4) inhibitors in urothelial carcinoma focusing our attention on the developing new immune-agents and combination strategies with immune-checkpoint inhibitors.

    Full Text Available Background. Intra-abdominal metastases of invasive lobular breast cancer (ILBC may be insidious. We report a case of metastatic ILBC that presented with dysphagia within weeks of a negative mammogram and before the development of intra-abdominal symptoms. Case. A 70-year-old female developed esophageal dysphagia. She underwent EGD which showed a short segment of stricture of the distal esophagus without significant mucosal changes. Biopsy was unremarkable and patient underwent lower esophageal sphincter (LES dilation. Severe progressive dysphagia led to esophageal impaction and three LES dilatations. CT scan showed bilateral pleural effusions, more prominent on right side, and ascites. The pleural effusions were transudative. Repeat EGD with biopsy showed lymphocytic esophagitis, and she was started on swallowed fluticasone. Abdominal ultrasound with Doppler showed that the main portal vein had atypical turbulent flow that was felt to possibly be due to retroperitoneal process. The patient underwent diagnostic laparoscopy which revealed diffuse punctate lesions on the peritoneum. Pathology was consistent with metastatic ILBC. Conclusion. Dysphagia in the setting of peritoneal carcinomatosis from metastatic ILBC is a rare finding. The case highlights the importance of metastatic ILBC as a differential diagnosis for female patients with progressive dysphagia and associated ascites or pleural effusions.

    Serum carcinoembryonic antigen (CEA) is the most commonly used tumor marker in a variety of cancers including colorectal cancer (CRC) for tumor diagnosis and monitoring. Recent studies have shown that colonic crypt cells expressing little or no CEA may enrich for stem cells. Numerous studies have clearly shown that there exist CRC patients with normal serum CEA levels during tumor progression or even tumor relapse, although CEA itself is considered to promote metastasis and block cell differentiation. These seemingly contradictory observations prompted us to investigate, herein, the biological properties as well as tumorigenic and metastatic capacity of CRC cells that express high (CEA+) versus low CEA (CEA−/lo) levels of CEA. Our findings show that the abundance of CEA−/lo cells correlate with poor differentiation and poor prognosis, and moreover, CEA−/lo cells form more spheres in vitro, generate more tumors and exhibit a higher potential in developing liver and lung metastases than corresponding CEA+ cells. Applying RNAi-mediated approach, we found that IGF1R mediated tumorigenic and capacity of CEA−/lo cells but did not mediate those of CEA+ cells. Notably, our data demonstrated that CEA molecule was capable of protecting CEA−/lo cells from anoikis, implying that CEA+ cells, although themselves possessing less tumorigenic and metastatic capacity, may promote metastasis of CEA−/lo cells via secreting CEA molecule. Our observations suggest that, besides targeting CEA molecule, CEA−/lo cells may represent a critical source of tumor progression and metastasis, and should therefore be the target of future therapies.

    2016-01-01

    A 48 year-old female presented to her primary care physician with a two-month history of neck pain with negative cervical spine x-rays. During that office visit, the patient was noted to be tachycardic with EKG revealing ST depressions, which led to hospital admission. Acute coronary syndrome was ruled out, however, persistent neck pain warranted inpatient MRI of the cervical spine, which revealed a cervical spine lesion. Extensive investigation and biopsy ultimately confirmed stage IV pancreatic adenocarcinoma with metastases to the bone, liver, and likely lung. In the literature, the findings of a primary metastatic site being bone is rare with only a few case reports showing vertebral or sternal metastasis as the first clinical manifestation of pancreatic cancer. The uniqueness of this case lies in the only presenting complaint being cervical spine pain in the setting of extensive metastases to the liver, bone, and likely lung.

    Background: Anticancer chemotherapy is thought to be effective by means of direct cytotoxicity on tumor cells. Alternative mechanisms of efficacy have been ascribed to several common anticancer agents; including cyclophosphamide (CTX) and capecitabine (Cap) when given at lower doses for prolonged period (metronomic chemotherapy) postulating an antiangiogenic activity as well, Aim of work :To evaluate the action and tolerability of metronomic chemotherapy (MC) and its impact on serum vascular endothetial growth factor (VEGF) levels in metastatic breast cancer (MBC) patients. Patients and methods: In this study we evaluated the clinical efficacy and tolerability of low dose, capecitabine (500 mg twice daily) together with oral cyclophosphamide (CTX) (a dose of 50 mg once daily) in patients with metastatic breast cancer. Vascular endothelial growth factor (VEGF), an angiogenic marker, was measured in the serum samples; at base line, and after 2 and 6 months of therapy. Results: Sixty patients were evaluable. One achieved complete response (CR), 12 partial responses (PR), and 21 stable diseases (SD), while 26 were with progressive disease (PD). The overall response rate was 21.7% with overall disease control (CR, PR, and SD) 56.7%. The median time to progression was 7±2.59 months and overall survival 16 ±8.02 months. Toxicity was mild, Palmar-plantar erythrodythesia was the must common side effect and was observed in 22 patients (37%), leucopenia (Gl + 2) was the most common hematological toxicity, and it was reported in 27% of the cases. The median VEGF level was significantly declined after 2 and 6 months of therapy compared to the base line among the patients with disease control (CR, PR, and SD). In multivariate logisatic regression analysis, patients with post-menopausal, positive hormonal receptors, negative HER-2/Neu, and one, metastatic site, were statistically significant and have a better disease control rate. Coclcusions: MC induced drop in VEGF, and was

    Purpose: This study was designed to evaluate short ( 3 months) follow-up in patients with metastatic neuroendocrine tumor to the liver who underwent hepatic arterial chemoembolization with drug-eluting beads at a single institution. Methods: Institutional review board approval was obtained for this retrospective review. All patients who were treated with 100–300 or 300–500 μm drug-eluting LC Beads (Biocompatibles, UK) preloaded with doxorubicin (range, 50–100 mg) for GI neuroendocrine tumor metastatic to the liver from June 2004 to June 2009 were included. CT and MRI were evaluated for progression using Response Evaluation Criteria In Solid Tumors (RECIST) or European Association for the Study of the Liver (EASL) criteria. Short-term ( 3 months) imaging response was determined and Kaplan–Meier survival curves were plotted. Results: Thirty-eight drug-eluting bead chemoembolization procedures were performed on 32 hepatic lobes, comprising 21 treatment cycles in 18 patients. All procedures were technically successful with two major complications (biliary injuries). At short-term follow-up (<3 months), 22 of 38 (58%) procedures and 10 of 21 (48%) treatment cycles produced an objective response (OR) with the remainder having stable disease (SD). At intermediate-term follow-up (mean, 445 days; range, 163–1247), 17 of 26 (65%) procedures and 8 of 14 (57%) treatment cycles produced an OR. Probability of progressing was approximately 52% at 1 year with a median time to progression of 419 days. Conclusions: Drug-eluting bead chemoembolization is a reasonable alternative to hepatic arterial embolization and chemoembolization for the treatment of metastatic neuroendocrine tumor to the liver.

    The role of IL6 in liver cancer linked to metabolic liver disease. Liver cancer is highly fatal, it has very few treatment options, and it is one of the few cancers whose incidence is rising worldwide. One poorly understood risk factor for liver cancer is obesity/metabolic disease (such as diabetes and fatty liver disease).

    2007-01-01

    Purpose: Recently we have demonstrated that our in-house developed algorithm for automated plan generation for fully non-coplanar SBRT of liver patients (designated Cycle) yields plans that are superior to conventionally generated plans of experienced dosimetrists. Here we use Cycle in the comparison of plans with prescription isodoses of 65% or 80% of the isocentre dose. Methods: Plans were generated using CT-data of 15 previously treated patients. For each patient, both for the 65%- and the 80% strategy, Cycle was used to generate a plan with the maximum isocentre dose, D isoc , while strictly obeying a set of hard constraints for the organs at risk (OAR). Plans for the two strategies were compared using D isoc , D PTV,99% (the minimum dose delivered to 99% of the PTV), and the generalised equivalent uniform dose, gEUD PTV (a), for several values of the parameter a. Moreover, for the OARs, the distance to the constraint values was analysed. Results: The 65% strategy resulted in treatment plans with a higher D isoc (average 17.6%, range 7.6-31.1%) than the 80% strategy, at the cost of a somewhat lower D PTV,99% (average -2.0%, range -9.6% to 9.3%). On average, voxels with a dose in the 65% strategy, lower than the minimum PTV dose in the 80% strategy, were within 0.2 cm from the PTV surface. For a ≥ -10, the 65% strategy yielded on average a significantly (P PTV (a) than the 80% strategy, whereas for highly negative a-values the 80% approach was slightly better, although not significantly. Large variations between patients were observed. Generally, for the OAR the approach to the constraint levels was similar for the two strategies. Conclusion: On average, PTV dose delivery is superior with the 65% strategy. However, apart from the isocentre dose, for each applied PTV dose parameter at least one patient would have been better off with the 80% dose prescription strategy

While several novel cytotoxic and biologic therapies have been developed and proven efficacious in the past two decades, their optimal use in terms of patient selection, drug combinations, and regimen sequences has yet to be defined. Recent investigations regarding anti-epidermal growth factor receptor therapies include the comparison of single-agent panitumumab and cetuximab, the benefit of adding cetuximab to chemotherapy in the conversion therapy setting, the comparison of cetuximab and bevacizumab when added to first-line chemotherapy, and predictive biomarkers beyond KRAS exon 2 (codons 12 and 13 mutations. With respect to anti-vascular endothelial growth factor therapies, new data on continuing bevacizumab beyond disease progression on a bevacizumab-containing chemotherapy regimen, the addition of bevacizumab to triplet chemotherapy in the first-line setting, maintenance therapy with bevacizumab plus either capecitabine or erlotinib, the addition of aflibercept to chemotherapy, and regorafenib as monotherapy have emerged. Recent scientific and technologic advances in the field of metastatic colorectal cancer promise to elucidate the biological underpinnings of this disease and its therapies for the goal of improving personalized treatments for patients with metastatic colorectal cancer.Keywords: cetuximab, panitumumab, bevacizumab, aflibercept, regorafenib, biomarker

    We constructed a multifunction nano system SWNT-GC and investigated the synergize photothermal and immunological effects. Here, we improve the SWNT-GC nano system and design a new synergistic nano-particle, both have the photothermal effects and immunological effects. We investigate the therapeutic effects and detect the immune response with metastatic mouse tumor models. We also study the therapeutic mechanism after treatment in vitro and in vivo. With the enhancement of nano-materials on photothermal effects, laser treatment could destroy primary tumor and protect normal tissue with low dose laser irradiation. With the immunological effects of nano-materials, the treatment could trigger specific antitumor immune response, to eliminate the metastasis tumor. It is providing a promising treatment modality for the metastatic cancers.

    Full Text Available Tuberculosis (TB may present as pulmonary and extra-pulmonary. TB lymphadenitis is the most common presentation of extra-pulmonary TB. TB lymphadenitis should be taken into account in the differential diagnosis of different disorders such as metastatic lymphadenopathy. The reported patient was a 65-year-old lady with breast cancer and conglomerated and matted axillary lymphadenopathy who received chemotherapy. She presented with more extensive axillary LAP contrary to our expectation. Modified radical mastectomy was done and pathology analysis reported TB lymphadenitis associated with metastatic LAP. Under cover of anti-TB therapy adjuvant chemoradiation therapy was started. Accordingly, we recommend TB be ruled out in every patient who needs chemotherapy in the endemic region because chemotherapy may cause the extension of TB in the body.

    Early identification of mutations may guide patients with metastatic colorectal cancer toward targeted therapies that may be life prolonging. The authors assessed tumor genotype correlations with clinical characteristics to determine whether mutational profiling can account for clinical similarities, differences, and outcomes. Under Institutional Review Board approval, 222 patients with metastatic colon adenocarcinoma (n = 158) and rectal adenocarcinoma (n = 64) who underwent clinical tumor genotyping were reviewed. Multiplexed tumor genotyping screened for >150 mutations across 15 commonly mutated cancer genes. The chi-square test was used to assess genotype frequency by tumor site and additional clinical characteristics. Cox multivariate analysis was used to assess the impact of genotype on overall survival. Broad-based tumor genotyping revealed clinical and anatomic differences that could be linked to gene mutations. NRAS mutations were associated with rectal cancer versus colon cancer (12.5% vs 0.6%; P colon cancer (13% vs 3%; P = .024) and older age (15.8% vs 4.6%; P = .006). TP53 mutations were associated with rectal cancer (30% vs 18%; P = .048), younger age (14% vs 28.7%; P = .007), and men (26.4% vs 14%; P = .03). Lung metastases were associated with PIK3CA mutations (23% vs 8.7%; P = .004). Only mutations in BRAF were independently associated with decreased overall survival (hazard ratio, 2.4; 95% confidence interval, 1.09-5.27; P = .029). The current study suggests that underlying molecular profiles can differ between colon and rectal cancers. Further investigation is warranted to assess whether the differences identified are important in determining the optimal treatment course for these patients. © 2014 American Cancer Society.

    Full Text Available Only orchiectomy is still commonly used today either as a single therapy or in combination regimens. Hypophysectomy & adrenalectomy showed such devastating effects on the endocrine equilibrium as to be inconsistent with an acceptable quality of life or even with survival. Chemical adrenalectomy was also tried with drugs (eg. aminoglutethmide, spironolactone leading to consequences superimposable to those of surgical adrenalectomy. Along with orchiectomy, three groups of substances are commonly used today for the hormonal therapy of prostate cancer: estrogens, LHRH agonists & anti androgens. Bilateral orchiectomy removes 90-95% of circulating testosterone. Clinical studies document 60-80% of positive responders to castration, on continued evaluation, relapse occurs usually within 6-24 months in responders, with a death rate of 50% within 6 months. The androgenic activity still remaining after castration may explain the partial & progressively decreasing effectiveness of this & other testosterone reducing therapies. Antiandrogens define substances that act directly at the target site, where interacting with steroid hormone receptors, they impede the binding of androgens. A trend towards the combination of testosterone-reducing & androgen-blocking treatment is developing in modern therapy of prostate cancer. This is due to the complementary characteristics of the two different pharmacological mechanisms that are involved. In this study castration+antiandrogen is compared to castration alone. The results demonstrate a significantly greater percentage of positive objective & subjective responses with antiandrogen than with placebo. In addition survival time was increased in patients treated with castration+antiandrogen than castration+placebo.

    Metastatic breast cancer is a disease of early breast cancer that usually occurs several years after the early breast cancer. Breast cancer is the most common cancer among Iranian women. According to the new statistics in Iran 6 160 breast cancers are diagnosed in the country each year and 1 063 cases lead to death. In this paper, epidemiology, diagnosis and treatment have been investigated. In this study, case-control clinical trials and open studies with adequate data were collected. Due to the higher risk of age group 40-49 years and the advent of advanced breast cancer in Iranian women, the early diagnosis and determination of the exact size of the tumor before surgery is important in choosing a therapy plan. The decision on the therapy of invasive breast cancer depends on several factors such as cancer stage, tumor size and type, pathological and cytological status of the tumor, the patient’s opinion, the presence or absence of estrogen and progesterone receptors in the cytoplasm of tumor cells and so on.

    Regorafenib is an oral multikinase inhibitor that has been demonstrated as clinically effective in patients with metastatic colorectal cancer in phase III studies. Although disease control was achieved in 40% of the pretreated patients with metastatic colorectal cancer in the pivotal studies, radiological response has rarely been reported. Severe adverse events associated with regorafenib are known to occur during the first and second courses of treatment. We present a case of a 62-year-old Japanese patient whose metastatic colorectal cancer has been responding to treatment with regorafenib for 2 years. A 54-year-old Japanese man visited our institute exhibiting general malaise, and he was diagnosed with ascending colon cancer in April 2006. He underwent right hemicolectomy, and the final staging was T3N0M0, stage II. After 19 months, pulmonary metastasis and anastomotic recurrences were detected, and a series of operations were performed to resect both metastatic lesions. After that, liver metastasis, a duodenal metastasis with right renal invasion, right adrenal metastasis, and para-aortic lymph node metastases were observed during follow-up, and chemotherapy and resection were performed. The patient had metastatic para-aortic lymph nodes after the fifth tumor resection and underwent multiple lines of chemotherapy in April 2014. Regorafenib monotherapy was started at 80 mg/day. Then, regorafenib was increased to 120 mg/day in the second cycle. Regorafenib monotherapy led to 60% tumor shrinkage within the initial 2 months, and the tumor further decreased in size over 4 months until it became unrecognizable on imaging studies. The clinical effects of regorafenib monotherapy have shown a partial response according to Response Evaluation Criteria in Solid Tumors criteria. No severe adverse events were observed, except for mild fatigue and hand-foot syndrome. The patient has received 24 courses of regorafenib over 2 years without exhibiting tumor progression. To the

    Metastasis is the major cause of low survival rates among cancer patients. Once cancer cells metastasize, it is extremely difficult to contain the disease. We report on a nanotextured platform for enhanced detection of metastatic cells. We captured metastatic (MDA-MDB-231) and non-metastatic (MCF-7) breast cancer cells on anti-EGFR aptamer modified plane and nanotextured substrates. Metastatic cells were seen to change their morphology at higher rates when captured on nanotextured substrates than on plane substrates. Analysis showed statistically different morphological behaviors of metastatic cells that were very pronounced on the nanotextured substrates. Several distance matrices were calculated to quantify the dissimilarity of cell shape change. Nanotexturing increased the dissimilarity of the metastatic cells and as a result the contrast between metastatic and non-metastatic cells increased. Jaccard distance measurements found that the shape change ratio of the non-metastatic and metastatic cells was enhanced from 1:1.01 to 1:1.81, going from plane to nanotextured substrates. The shape change ratio of the non-metastatic to metastatic cells improved from 1:1.48 to 1:2.19 for the Hausdorff distance and from 1:1.87 to 1:4.69 for the Mahalanobis distance after introducing nanotexture. Distance matrix analysis showed that nanotexture increased the shape change ratios of non-metastatic and metastatic cells. Hence, the detectability of metastatic cells increased. These calculated matrices provided clear and explicit measures to discriminate single cells for their metastatic state on functional nanotextured substrates.

    Background The aim of this study was to evaluate the prognostic importance of the metastatic lymph node ratio for stage III colon cancer patients and to find a cut-off value at which the overall survival and disease-free survival change. Material/Methods Patients with pathological stage III colon cancer were retrospectively evaluated for: age; preoperative values of Crp, Cea, Ca 19-9, and Afp; pathologic situation of vascular, perineural, lymphatic, and serosal involvement; and metastatic lymph node ratio values were calculated. Results The study included 58 stage III colon cancer patients: 20 (34.5%) females and 38 (65.5%) males were involved in the study. Multivariate analysis was applied to the following variables to evaluate significance for overall survival and disease-free survival: age, Crp, Cea, perineural invasion, and metastatic lymph node ratio. The metastatic lymph node ratio (<0.25 or ≥0.25) is the only independent variable significant for overall and disease-free survival. Conclusions Metastatic lymph node ratio is an ideal prognostic marker for stage III colon cancer patients, and 0.25 is the cut-off value for prognosis. PMID:25087904

    Full Text Available The thyroid is an unusual site to find cancer metastasis. When it does occur, such cancer spread is often manifested in multiple metastases and generally suggests a poor prognosis. We presented here a 49-year-old woman recently diagnosed with thyroid cancer, who had been treated for stage IIA breast cancer 8 years ago. After radical right thyroidectomy and left subtotal thyroidectomy, her pathological report showed papillary thyroid carcinoma, right thyroid, with concomitant metastatic breast carcinoma. This is the first case of which we are aware involving coexisting thyroid cancer and metastatic breast cancer in the ipsilateral lobe. Moreover, the circumstances of this case show a very unique clinical course compared with previous studies. Given the unusual circumstances of our case, we further discuss the relationship between thyroid cancer and breast cancer.

Despite certain success, targeted antiangiogenetic therapy with tyrosine kinase inhibitors, mammalian target of rapamycin inhibitors (mTOR, and monoclonal antibodies against vascular endothelial growth factor (VEGF in most cases do not achieve long-term remission, are highly toxic, and never lead to full cure for the patients. Development of modern immunological approaches to application of inhibitors of the crucial immune response regulators opens up new possibilities in treatment of disseminated kidney cancer.

    2013-01-01

    Full Text Available This article is devoted to modern approaches in HER-2-positive metastatic breast cancer therapy. Recently treatment algorithm for this type of cancer included trastuzumab plus cytostatic in first line, continuation of trastuzumab with another chemotherapy regimen in second line, further switch to lapatinib and eventual return to trastuzumab after progression. Nowadays our options are broader owing to new anti-HER-2 agents which are pertruzumab and T-DM1. Now the most effective therapy regimen in first line is double HER-2 blockade (trastuzumab + pertuzumab in combination with docetaxel. Benefit of new agent T-DM1 versus combination of lapatinib and capecitabin is proved in patients progressed on trastuzumab and taxanes. T-DM1 also showed high efficacy as salvage therapy in intensively pretreated patients with meta- static HER-2-positive breast cancer who progressed on taxanes, trastuzumab and lapatinib.

    The purpose of this retrospective study is to evaluate the effectiveness of gamma knife radiosurgery (GKS) alone for metastatic brain tumors from lung cancer. Two hundred thirty-one consecutive patients with metastatic brain tumors from lung cancer filling the following 4 criteria were analyzed for this study; no prior brain tumor treatment, 25 or fewer lesions, a maximum 5 tumors with diameter of 2 cm or more, no surgically inaccessible tumor 3 cm or greater in diameter. According to the same treatment protocol, large tumors ({>=} 3 cm) were surgically removed and all the other small lesions (<3 cm) were treated with GKS. New lesions were treated with repeated GKS. The tumor-progression-free, overall, neurological, lowered-QOL (quality of life)-free and new-lesion-free survivals were calculated with the Kaplan-Meier method. The poor prognostic factors for each survival were also analyzed with the Cox's proportional hazard model. The tumor control rate at 1 year was 96.5%. The estimated median overall survival time was 7.7 months. The first-year survival rates were 83.0% in neurological survival and 76.0% in lowered-QOL-free survival. The new-lesion-free survival at 1 year was 27.9%. Multivariate analysis revealed significant poor prognostic factors for neurological and lowered-QOL-free survivals were carcinomatous meningitis and >10 brain lesions. This study suggests the results of GKS for metastatic brain tumors from lung cancer are quite satisfactory considering prevention of neurological death and maintenance of QOL. But cases with carcinomatous meningitis and/or >10 brain lesions are not good candidates for GKS alone. (author)

    Full Text Available ABSTRACT Introduction To characterize initial presentation and PSA screening status in a contemporary cohort of men treated for metastatic prostate cancer at our institution. Materials and methods We reviewed records of 160 men treated for metastatic prostate cancer between 2008-2014 and assessed initial presentation, categorizing patients into four groups. Groups 1 and 2 presented with localized disease and received treatment. These men suffered biochemical recurrence late (>1 year or earlier (<1 year, respectively, and developed metastases. Groups 3 and 4 had asymptomatic and symptomatic metastases at the outset of their diagnosis. Patients with a first PSA at age 55 or younger were considered to have guideline-directed screening. Results Complete records were available on 157 men for initial presentation and 155 men for PSA screening. Groups 1, 2, 3 and 4 included 27 (17%, 7 (5%, 69 (44% and 54 (34% patients, respectively. Twenty (13% patients received guideline-directed PSA screening, 5/155 (3% patients presented with metastases prior to age 55 with their first PSA, and 130/155 (84% had their first PSA after age 55, of which 122/130 (94% had metastasis at the time of diagnosis. Conclusion Despite widespread screening, most men treated for metastatic prostate cancer at our institution presented with metastases rather than progressed after definitive treatment. Furthermore, 25 (16% patients received guideline-directed PSA screening at or before age 55. These data highlight that, despite mass screening efforts, patients treated for incurable disease at our institution may not have been a result of a failed screening test, but a failure to be screened.

    ABSTRACT Introduction To characterize initial presentation and PSA screening status in a contemporary cohort of men treated for metastatic prostate cancer at our institution. Materials and methods We reviewed records of 160 men treated for metastatic prostate cancer between 2008-2014 and assessed initial presentation, categorizing patients into four groups. Groups 1 and 2 presented with localized disease and received treatment. These men suffered biochemical recurrence late (>1 year) or earlier (<1 year), respectively, and developed metastases. Groups 3 and 4 had asymptomatic and symptomatic metastases at the outset of their diagnosis. Patients with a first PSA at age 55 or younger were considered to have guideline-directed screening. Results Complete records were available on 157 men for initial presentation and 155 men for PSA screening. Groups 1, 2, 3 and 4 included 27 (17%), 7 (5%), 69 (44%) and 54 (34%) patients, respectively. Twenty (13%) patients received guideline-directed PSA screening, 5/155 (3%) patients presented with metastases prior to age 55 with their first PSA, and 130/155 (84%) had their first PSA after age 55, of which 122/130 (94%) had metastasis at the time of diagnosis. Conclusion Despite widespread screening, most men treated for metastatic prostate cancer at our institution presented with metastases rather than progressed after definitive treatment. Furthermore, 25 (16%) patients received guideline-directed PSA screening at or before age 55. These data highlight that, despite mass screening efforts, patients treated for incurable disease at our institution may not have been a result of a failed screening test, but a failure to be screened.

    Using an integrative genomics approach called Amplification Breakpoint Ranking and Assembly (ABRA) analysis, we nominated KRAS as a gene fusion with the ubiquitin-conjugating enzyme UBE2L3 in the DU145 cell line, originally derived from prostate cancer metastasis to the brain. Interestingly, analysis of tissues revealed that 2 of 62 metastatic prostate cancers harbored aberrations at the KRAS locus. In DU145 cells, UBE2L3-KRAS produces a fusion protein, specific knock-down of which, attenuates cell invasion and xenograft growth. Ectopic expression of the UBE2L3-KRAS fusion protein exhibits transforming activity in NIH 3T3 fibroblasts and RWPE prostate epithelial cells in vitro and in vivo. In NIH 3T3 cells, UBE2L3-KRAS attenuates MEK/ERK signaling, commonly engaged by oncogenic mutant KRAS, and instead signals via AKT and p38 MAPK pathways. This is the first report of a gene fusion involving Ras family suggesting that this aberration may drive metastatic progression in a rare subset of prostate cancers. PMID:22140652

    The most common sites of colorectal cancer (CRC) recurrence are the local tissues, liver or lungs. The objective was to identify risk factors associated with the primary CRC tumor and cancer recurrence in these anatomical sites. Retrospective, longitudinal analyses of data on CRC survivors. Multivariable Cox regression analysis was performed to examine the association between possible cofounders with recurrence to various anatomical sites. Data for 10,398CRC survivors (tumor location right colon=3870, left colon=2898, high rectum=2569, low rectum=1061) were analyzed; follow up time was up to five years. Mean age at curative surgery was 71.5 (SD 11.8) years, 20.2% received radio-chemotherapy, stage T3 (64.4%) and N0 (65.1%) were most common. Overall 1632 (15.7%) had cancer recurrence (Isolated liver n=412, 3,8%;  isolated lung n=252, 2,4%; isolated local n=223, 2.1%). Risk factors associated with recurrent CRC were identified, i.e. isolated liver metastases (male: Adjusted Hazard Ratio (AHR) 1,45; colon left: AHR 1,63; N2 disease: AHR 3,35; T2 disease: AHR 2,82), isolated lung metastases (colon left: AHR 1,53; rectum high: AHR 2,48; rectum low: AHR 2,65; N2 disease 3,76), and local recurrence (glands examined<12: AHR 1,51; CRM <3mm: AHR 1,60; rectum high: AHR 2,15; N2 disease: AHR 2,58) (all p values <0001). Our study finds that the site of the primary CRC tumor is associated with location of subsequent metastasis. Left sided colon cancers have increased risk of metastatic spread to the liver, whereas rectal cancers have increased risk of local recurrence and metastatic spread to the lungs. These results, in combination with other risk factors for CRC recurrence, should be taken into consideration when designing risk adapted post-treatment CRC surveillance programs.

    A 44-year-old woman underwent two PET-CT scans for the evaluation of metastatic breast cancer. A radical left mastectomy with axillary dissection (1 of 43 nodes positive) followed by chemotherapy, was performed in 1998. She represented in October 2003 with a left supraclavicular fossa mass. This was confirmed to be recurrent breast cancer on FNAB. She was considered for a radical neck dissection and the surgeon requested a PET scan. Other imaging at this time included a normal bone scan and CT brain. CT neck/chest/abdomen/pelvis showed soft tissue thickening in the left lower neck. The PET-CT scan showed multiple glucose avid lesions in the sternum, mediastinum and neck lymph nodes as well as a small lesion in the proximal left femur consistent with extensive metastatic disease. Surgery was cancelled and Femara chemotherapy commenced. Femara was stopped in March 2004 and the patient began alternative therapies. In October 2004 she presented to her surgeon with new back and chest pain. CT of the neck/chest/abdomen/pelvis showed a soft tissue mass in the upper sternum and a lymph node at the base of the neck highly suspicious for metastatic disease. There were also 2 suspicious lung nodules and a lesion in the proximal left femur reported as an osteoid osteoma. Wholebody PET-CT scans were performed on a Siemens LSO Biograph, 60mins after the injection of 350Mbq of Fl 8-Fag, with arms at the patient's side and head in the field-of-view. On both occasions the patient had to pay for the scan. On the 2004 PET-CT scan, the CT brain revealed multiple hyperdense lesions consistent with hemorrhagic metastases. In addition, there were innumerable glucose avid foci involving viscera, nodes and skeleton consistent with disseminated disease. Our case illustrates: (i) the value of PET in the management of metastatic breast cancer; (ii) the improved accuracy of PET-CT in delineating sites of disease; (iii) the issues of head movement in PET-CT and. (iv) the problem with lack of

    Chyle fistula (CF) is a rare but challenging condition for the surgeon and the patient's health. A retrospective review of single surgeon's case load in a 12-year period is presented, reviewing the case of those patients presenting with a CF. Three patients were found during this study period from more than 1,050 surgeries performed due to thyroid cancer. Patients underwent extensive lymph node dissection for advanced, metastatic and infiltrative disease. In all patients, a long hospital stay and surgical re-interventions were required. A description of the management of CF is presented along with a review of current Literature.

    The improved survival following the diagnosis of breast cancer has potentially altered the characteristics and course of patients presenting with CNS involvement. We therefore sought to define our current cohort of breast cancer patients with metastatic disease to the CNS in regard to modern biomarkers and clinical outcome. Review of clinical and radiographic records of women presenting to a tertiary medical center with the new diagnosis of CNS metastatic disease from breast cancer. This was a retrospective review from patients identities obtained from two prospective databases. There were 88 women analyzed who were treated over the period of January 2003 to February 2010, average age 56.9 years. At the time of initial presentation of CNS disease, 68 % of patients had multiple brain metastases, 17 % had a solitary metastasis, and 15 % had only leptomeningeal disease (LMD). The median survival for all patients from the time of diagnosis of breast disease was 50.0 months, and 9.7 months from diagnosis of CNS involvement. The only factor related to overall survival was estrogen receptor-positive pathology (57.6 v. 38.2 months, p = .02 log-rank); those related to survival post CNS diagnosis were presentation with LMD (p = .004, HR = 3.1, Cox regression) and triple-negative hormonal/HER2 status (p = .02, HR = 2.3, Cox regression). Patients with either had a median survival of 3.1 months (no patients in common). Of the 75 patients who initially presented with metastatic brain lesions, 20 (26 %) subsequently developed LMD in the course of their disease (median 10.4 months), following which survival was grim (1.8 months median). Symptoms of LMD were most commonly lower extremity weakness (14/33), followed by cranial nerve deficits (11/33). The recently described Graded Prognostic Assessment (GPA) tumor index stratified median survival at 2.5, 5.9, 13.1, and 21.7 months, respectively, for indices of 1-4 (p = .004, log-rank), which

    Targeted agents are an important therapeutic option in the treatment of metastatic colorectal cancer (mCRC). Panitumumab is a recombinant, fully humanized, immunoglobulin G2 monoclonal antibody that targets the epidermal growth factor receptor (EGFR) with efficacy in mCRC as monotherapy and in combination with chemotherapy. Kirsten rat sarcoma (KRAS) mutation status has emerged as an important biomarker to predict response to anti-EGFR therapy. Optimal timing for panitumumab use in the mCRC treatment algorithm has not been established. This review discusses the mechanism of action, predictive biomarkers, and role of panitumumab in the treatment of mCRC

    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; alpha-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 reevaluated 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.

    Patients (pts) with metastatic rectal cancer and symptomatic primary, require local and systemic control. Chemotherapy used during chemoradiotherapy (CRT) is adequate for radiosensitisation, but suboptimal for systemic control. The aim of this phase II study was to assess tolerability, local/systemic benefits, of a novel regimen delivering interdigitating intensive chemotherapy with radical CRT. Eligible pts had untreated synchronous symptomatic primary/metastatic rectal cancer. A total of 12 weeks of treatment with split-course pelvic CRT (total 50.4 Gy with concurrent oxaliplatin and 5-FU infusion) alternating with FOLFOX chemotherapy. All pts staged with CT, MRI and FDG-PET pre and post treatment. Twenty-six pts were treated. Rectal primary MRI stage: T3 81% and T4 15%. Liver metastases in 81%. Twenty-four pts (92%) completed the 12-week regimen. All patients received planned RT dose, and for both agents over 88% of patients achieved a relative dose intensity of >75%. Grade 3 toxicities: neutropenia 23%, diarrhoea 15%, and radiation skin reaction 12%. Grade 4 toxicity: neutropenia 15%. FDG-PET metabolic response rate for rectal primary 96%, and for metastatic disease 60%. Delivery of interdigitating chemotherapy with radical CRT was feasible to treat both primary and metastatic rectal cancer. High completion and response rates were encouraging.

    To analyze the prognostic influence of metastatic pattern (MP) compared with other biologic and clinical factors in stage IV breast cancer at initial diagnosis (BCID) and evaluate factors associated with specific sites of metastases (SSM). We evaluated women with stage IV BCID with known metastatic sites, reported to the Surveillance, Epidemiology and End Results program from 2010 to 2013. MP was categorized as bone-only, visceral, bone and visceral (BV), and other. Univariate and multivariate analyses determined the effects of each variable on overall survival (OS). Logistic regression examined factors associated with SSM. We included 9143 patients. Bone represented 37.5% of patients, visceral 21.9%, BV 28.8%, and other 11.9%. Median OS by MP was as follows: bone 38 months, visceral 21 months, BV 19 months, and other 33 months (P < 0.0001). Univariate analysis showed that higher number of metastatic sites had worse prognosis. In multivariate analysis, older age (hazard ratio 1.9), black race (hazard ratio 1.17), grade 3/4 tumors (hazard ratio 1.6), triple-negative (hazard ratio 2.24), BV MP (hazard ratio 2.07), and unmarried patients (hazard ratio 1.25) had significantly shorter OS. As compared with HR+/HER2- tumors, triple-negative and HR-/HER2+ had higher odds of brain, liver, lung, and other metastases. HR+/HER2+ had higher odds of liver metastases. All three subtypes had lower odds of bone metastases. There were substantial differences in OS according to MP. Tumor subtypes have a clear influence among other factors on SSM. We identified several prognostic factors that could guide therapy selection in treatment naïve patients.

    Metastatic gastric cancer is uncommon, and metastasis of colorectal cancer to the stomach is extremely rare. We report a case of metastatic gastric cancer that originated from transverse colon cancer. A 52-year-old woman underwent a left hemicolectomy and D3 lymph node dissection based on a diagnosis of transverse colon cancer. The pathology results were as follows: mucinous adenocarcinoma, type 2, 6 × 11 cm, ss, ly1 v1, pm (-), dm (-), n1 (+), P0, H0, M0, Stage IIIa. The patient received XELOX as postoperative adjuvant therapy for 6 months. One year and 3 months after the left hemicolectomy, gastroscopy revealed a submucosal tumor in the lower body of the stomach and an incipient cancer in the cardia of the stomach, and a colonoscopy revealed an incipient cancer in the transverse colon. An endoscopic ultrasonography fine needle aspiration biopsy of the submucosal tumor in the lower body of the stomach was performed. Histology showed that this tumor was a mucinous adenocarcinoma similar to the primary transverse colon cancer, which led to a diagnosis of metastatic gastric cancer originating from transverse colon cancer. Distant metastasis was not detected. Endoscopic submucosal dissection of the incipient gastric cancer was performed, as were distal gastrectomy and partial colectomy. Peritoneal dissemination and para-aortic lymph node recurrence were detected 7 months after the second surgery.

    Full Text Available Abstract The most common sites of breast cancer metastasis are the bone, lung, liver and brain. However, colonic metastases from breast cancer are very rare in the clinic. We describe an unusual case of sigmoid colonic metastasis from invasive ductal breast cancer. With this report, we should increase the clinical awareness that any patient with a colorectal lesion and a history of malignancy should be considered to have a metastasis until proven otherwise. Early diagnosis is very important, which enables prompt initiation of systemic treatment, such as chemotherapy, endocrine therapy or both, thus avoiding unnecessary radical surgical resection and improving the prognosis.

    Full Text Available The aims of this study were first to clearly define two different entities: locoregional recurrences and limited metastatic disease and secondly to evaluate the place of extensive surgery in these two types of recurrence. Material and Methods. Twenty-four patients were followed from June 2004 until May 2014. All patients underwent surgery but for 1 patient this surgery was stopped because the tumour was unresectable. Results. The median interval between surgery for the primary tumour and the locoregional recurrence or metastatic evolution was 129 months. Eight patients had pure nodal recurrences, 4 had nodal and muscular recurrences, 5 had muscular + skin recurrences, and 8 had metastatic evolution. Currently, all patients are still alive but 2 have liver metastases. Disease free survival was measured at 2 years and extrapolated at 5 years and was 92% at these two time points. No difference was observed for young or older women; limited metastatic evolution and locoregional recurrence exhibited the same disease free survival. Conclusion. Extensive surgery has a place in locoregional and limited metastatic breast cancer recurrences but this option must absolutely be integrated in the multidisciplinary strategy of therapeutic options and needs to be planned with a curative intent.

    Metastatic colorectal carcinoma to the liver remains a formidable challenge. Responses to chemotherapy are brief and the number of effective drugs is very limited. A phase II trial of hepatic hyperthermia and intraarterial chemotherapy was undertaken to attempt to improve response rates and duration. Patients were given a 10 day course of IA 5-FU at 15 mg/kg. During the infusion hyperthermia was given five times using the BSD Annular Phased Array (APA). Thermistors were placed percutaneously into normal liver and tumor using ultrasound or CT scan guidance. Six patients have been treated. Significant problems in positioning ill patients in the APA were encountered, and there was difficulty also in preventing heating throughout the abdominal cavity. Four patients, all with poor performance status, failed to benefit. One patient had improvement in liver function studies for two months and failed to respond on a repeat course. One patient had a complete response which is continuing over 18 months with a liver scan reverting to normal and CEA returning to normal. These preliminary results are promising and warrant further trials

    To clarify the characteristic features of MR imagings of metastatic adenocarcinomas to the brain and search for differential points between the lesions from colorectal cancer and those of lung cancer, we evaluated retrospectively intraparenchymal metastatic lesions of 13 colorectal origins and 13 pulmonary origins on MR imagings, compared with resected specimens. Metastatic lesions from colorectal cancer showed marked hypointense solid components on T2WI, which correspond to the dense tumor cells and coagulated necrosis pathologically. Metastatic lesions from lung cancers showed mixed intensity and various components on T2WI, which correspond to various histological components, such as solid tumor cell's nests, hemorrhage, necrosis and cystic fluid collection. Pathological specimens suggested that the low signal intensity on T2WI of MRI derived from concentration of tumor cells and coagulated necrosis including macrophages and lymphocytes. This study may contribute to make the differential diagnosis of metastatic adenocarcinomas to the brain from colorectal and pulmonary cancers. (author)

    Germline mutations in ATM (encoding the DNA-damage signaling kinase, ataxia-telangiectasia-mutated) increase Familial Pancreatic Cancer (FPC) susceptibility, and ATM somatic mutations have been identified in resected human pancreatic tumors. Here we investigated how Atm contributes to pancreatic cancer by deleting this gene in a murine model of the disease expressing oncogenic Kras (Kras G12D ). We show that partial or total ATM deficiency cooperates with Kras G12D to promote highly metastatic pancreatic cancer. We also reveal that ATM is activated in pancreatic precancerous lesions in the context of DNA damage and cell proliferation, and demonstrate that ATM deficiency leads to persistent DNA damage in both precancerous lesions and primary tumors. Using low passage cultures from primary tumors and liver metastases we show that ATM loss accelerates Kras-induced carcinogenesis without conferring a specific phenotype to pancreatic tumors or changing the status of the tumor suppressors p53, p16 Ink4a and p19 Arf . However, ATM deficiency markedly increases the proportion of chromosomal alterations in pancreatic primary tumors and liver metastases. More importantly, ATM deficiency also renders murine pancreatic tumors highly sensitive to radiation. These and other findings in our study conclusively establish that ATM activity poses a major barrier to oncogenic transformation in the pancreas via maintaining genomic stability.

    Metastatic breast cancer (MBC) is an incurable disease and treatment is directed towards symptom palliation and survival prolongation. Treatment selection in patients is based on tumor biology, age, comorbidities, performance status, tumor burden, and prior treatment history. Areas covered: This present review summarizes the recent treatment strategies in the management of MBC, highlighting regimens after first-line therapy. Topics discussed include new strategies for endocrine therapy, anti-HER2 therapy, and promising strategies for the management of triple negative breast cancer. Expert opinion: MBC is a heterogeneous entity and despite recent advances, there is significant room for improvement of treatment beyond first-line therapies. Combination regimens that can maximize clinical efficacy while minimizing toxicities are required. Current investigation approaches in advanced stages of clinical development include immunoconjugates, immune checkpoint blockade, novel cyclin-dependent-kinase inhibitors, and PARP inhibitors for MBC associated with germline BRCA mutations. We recommend that every patient with MBC should be evaluated for clinical trial options.

    In the present work, we report on the results of our pilot study of hyperthermic isolated hepatic perfusion (IHP) with melphalan alone for patients with unresectable metastatic liver tumors refractory to conventional treatments, with particular regard to the correlation between pharmacokinetic findings and hepatic toxicity. Inclusion criteria were unresectable liver metastases, hepatic parenchyma replacement liver function, and previous failure of at least one conventional treatment. IHP was performed under hyperthermic conditions with melphalan (1.5 mg/kg body weight). Completeness of vascular isolation of the liver and drug distribution volumes of the perfusion circuit were assessed by a radiolabeled albumin-based method. Drug concentrations in perfusate and plasma were measured by means of high-performance liquid chromatography (HPLC). Twenty patients with unresectable liver metastases underwent IHP. No intraoperative mortality occurred. Treatment-related systemic toxicity was minimal and reversible. Three patients (15%) experienced grade 4 hepatic toxicity and died due to liver failure and subsequent multiorgan failure. Other six patients had significant (grade 3-4) but transitory hepatic toxicity. Complete and partial responses were observed in three and nine out of 17 evaluable patients, respectively (overall response rate = 70%). The pharmacokinetics study showed a 3% mean perfusate-to-plasma drug leakage (range 1-6%). Logistic regression analysis showed that drug concentration in the perfusate circuit, but not preoperative tests, significantly and independently correlated with hepatic toxicity (P = 0.028). Following melphalan-based IHP, objective tumor regression could be observed in a remarkable percentage of patients refractory to standard treatments. However, hepatic toxicity and related mortality were significant. Our findings suggest that drug dosage personalization based on the measurement of drug distribution volumes might minimize

    Full Text Available Abstract Background Newer systemic therapies have the potential to decrease morbidity and mortality from metastatic colorectal cancer, yet such therapies are costly and have side effects. Little is known about their non-evidence-based use. Methods We conducted a retrospective cohort study using commercial insurance claims from UnitedHealthcare, and identified incident cases of metastatic colon cancer (mCC from July 2007 through April 2010. We evaluated the use of three regimens with recommendations against their use in the National Comprehensive Cancer Center Network Guidelines, a commonly used standard of care: 1 bevacizumab beyond progression; 2 single agent capecitabine as a salvage therapy after failure on a fluoropyridimidine-containing regimen; 3 panitumumab or cetuximab after progression on a prior epidermal growth factor receptor antibody. We performed sensitivity analyses of key assumptions regarding cohort selection. Costs from a payer perspective were estimated using the average sales price for the entire duration and based on the number of claims. Results A total of 7642 patients with incident colon cancer were identified, of which 1041 (14% had mCC. Of those, 139 (13% potentially received at least one of the three unsupported off-label (UOL therapies; capecitabine was administered to 121 patients and 49 (40% likely received it outside of clinical guidelines, at an estimated cost of $718,000 for 218 claims. Thirty-eight patients received panitumumab and six patients (16% received it after being on cetuximab at least two months, at an estimated cost of $69,500 for 19 claims. Bevacizumab was administered to 884 patients. Of those, 90 (10% patients received it outside of clinical guidelines, at an estimated costs of $1.34 million for 636 claims. Conclusions In a large privately insured mCC cohort, a substantial number of patients potentially received UOL treatment. The economic costs and treatment toxicities of these therapies warrant

    Predicting any future metastatic site of early-stage breast cancer is important as it significantly influences the prognosis of advanced disease. This study aimed at investigating the potential of claudin-2, over-expressed in breast cancer liver metastases, as a biomarker for predicting liver metastatic propensity in primary breast cancer. Claudin-2 expression was analyzed in two independent cohorts. Cohort 1 included 304 women with metastatic breast cancer diagnosed between 2002 and 2007, while cohort 2 included 237 premenopausal women with early-stage node-negative breast cancer diagnosed between 1991 and 1994. Global transcriptional profiling of fine-needle aspirates from metastases was performed, followed by immunohistochemical analyses in archival primary tumor tissue. Associations between claudin-2 expression and relapse site were assessed by univariable and multivariable Cox regression models including conventional prognostic factors. Two-sided statistical tests were used. CLDN2 was significantly up-regulated (P diagnosis and liver-specific recurrence was observed among patients with high levels of claudin-2 expression in the primary tumor (cohort 1, HR = 2.3, 95% CI = 1.3-3.9). These results suggest a novel role for claudin-2 as a prognostic biomarker with the ability to predict not only the likelihood of a breast cancer recurrence, but more interestingly, the liver metastatic potential of the primary tumor.

    2007-12-15

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

    Abiraterone acetate, a drug that blocks endogenous androgen synthesis, plus prednisone is indicated for metastatic castration-resistant prostate cancer. We evaluated the clinical benefit of abiraterone acetate plus prednisone with androgen-deprivation therapy in patients with newly diagnosed, metastatic, castration-sensitive prostate cancer. In this double-blind, placebo-controlled, phase 3 trial, we randomly assigned 1199 patients to receive either androgen-deprivation therapy plus abiraterone acetate (1000 mg daily, given once daily as four 250-mg tablets) plus prednisone (5 mg daily) (the abiraterone group) or androgen-deprivation therapy plus dual placebos (the placebo group). The two primary end points were overall survival and radiographic progression-free survival. After a median follow-up of 30.4 months at a planned interim analysis (after 406 patients had died), the median overall survival was significantly longer in the abiraterone group than in the placebo group (not reached vs. 34.7 months) (hazard ratio for death, 0.62; 95% confidence interval [CI], 0.51 to 0.76; P<0.001). The median length of radiographic progression-free survival was 33.0 months in the abiraterone group and 14.8 months in the placebo group (hazard ratio for disease progression or death, 0.47; 95% CI, 0.39 to 0.55; P<0.001). Significantly better outcomes in all secondary end points were observed in the abiraterone group, including the time until pain progression, next subsequent therapy for prostate cancer, initiation of chemotherapy, and prostate-specific antigen progression (P<0.001 for all comparisons), along with next symptomatic skeletal events (P=0.009). These findings led to the unanimous recommendation by the independent data and safety monitoring committee that the trial be unblinded and crossover be allowed for patients in the placebo group to receive abiraterone. Rates of grade 3 hypertension and hypokalemia were higher in the abiraterone group. The addition of abiraterone

    Full Text Available A 64-year-old man was initially diagnosed with rectal cancer and liver metastasis. He underwent rectal amputation and partial hepatectomy. mFOLFOX6 was begun as first-line chemotherapy, but multiple pulmonary and right femoral lymph node metastases were found 1 year postoperatively. FOLFIRI plus bevacizumab was then started, but the tumors recurred after 2 years and 11 months. The regimen was changed to cetuximab with CPT-11. The lesions partially responded after 3 months, and the patient was free from progression for 1.5 years. Four years and 7 months after the adjuvant chemotherapy was started, the metastatic lesions gradually increased again, and the regimen was changed to panitumumab. After 2 months, the lesions had markedly decreased again and showed a partial response for 6 months. Although the pulmonary lesions became progressive again, the patient has been alive for 5 years and 8 months since the first operation.

    This article outlines the current Australian multidisciplinary treatment of synchronous metastatic colorectal adenocarcinoma and assesses the factors that influence patient outcome. This is a retrospective analysis of the prospective 'Treatment of Recurrent and Advanced Colorectal Cancer' registry, describing the patient treatment pathway and documenting the extent of disease, resection of the colorectal primary and metastases, chemotherapy and biological therapy use. Cox regression models for progression-free and overall survival were constructed with a comprehensive set of clinical variables. Analysis was intentionn-ton-treat, quantifying the effect of treatment intent decided at the multidisciplinary team meeting (MDT). One thousand one hundred and nine patients presented with synchronous metastatic disease between July 2009 and November 2015. Median follow-up was 15.8 months; 4.4% (group 1) had already curative resections of primary and metastases prior to MDT, 22.2% (group 2) were considered curative but were referred to MDT for opinion and/or medical oncology treatment prior to resection and 70.2% were considered palliative at MDT (group 3). Overall, 83% received chemotherapy, 55% had their primary resected and 23% had their metastases resected; 13% of resections were synchronous, 20% were staged with primary resected first and 62% had only the colorectal primary managed surgically. Performance status, metastasis resection (R0 versus R1 versus R2 versus no resection), resection of the colorectal primary and treatment intent determined at MDT were the most significant factors for progression-free and overall survival. This is the largest Australian series of synchronous metastatic colorectal adenocarcinoma and offers insight into the nature and utility of contemporary practice. © 2016 Royal Australasian College of Surgeons.

    Full Text Available Context Capecitabine, an oral drug, is as effective as traditional chemotherapy drugs. Objectives To investigate the adhesion to treatment with oral capecitabine in breast and colorectal cancer, and to determine any correlation with changes in patient’s quality of life. Methods Patients with colorectal cancer or breast cancer using capecitabine were included. The patients were asked to bring any medication left at the time of scheduled visits. The QLQ-C30 questionnaire was applied at the first visit and 8-12 weeks after treatment. Results Thirty patients were evaluated. Adherence was 88.3% for metastatic colon cancer, 90.4% for non-metastatic colon cancer, 94.3% for rectal cancer and 96.2% for metastatic breast cancer. No strong correlation between adherence and European Organisation for Research and Treatment of Cancer QLQ-C30 functional or symptom scale rates had been found. There was no statistically significant correlation between compliance and the functional and symptom scales of the questionnaire before and after chemotherapy, with the exception of dyspnea. Conclusions Although no absolute adherence to oral capecitabine treatment had been observed, the level of adherence was good. Health professionals therefore need a greater focus in the monitoring the involvement of patients with oral treatment regimens. Patients with lesser degrees of dyspnea had greater compliance.

  1. Changes in cytoskeletal dynamics and nonlinear rheology with metastatic ability in cancer cell lines

    2013-01-01

    Metastatic outcome is impacted by the biophysical state of the primary tumor cell. To determine if changes in cancer cell biophysical properties facilitate metastasis, we quantified cytoskeletal biophysics in well-characterized human skin, bladder, prostate and kidney cell line pairs that differ in metastatic ability. Using magnetic twisting cytometry with optical detection, cytoskeletal dynamics was observed through spontaneous motion of surface bound marker beads and nonlinear rheology was characterized through large amplitude forced oscillations of probe beads. Measurements of cytoskeletal dynamics and nonlinear rheology differed between strongly and weakly metastatic cells. However, no set of biophysical parameters changed systematically with metastatic ability across all cell lines. Compared to their weakly metastatic counterparts, the strongly metastatic kidney cancer cells exhibited both increased cytoskeletal dynamics and stiffness at large deformation which are thought to facilitate the process of vascular invasion.

    Significant improvements in neurological function and pain relief are the benefits of aggressive surgical management of spinal metastatic disease. However, there is limited literature regarding the management of tumors with specific histological features. In this study, a series of patients undergoing spinal surgery for metastatic prostate cancer were reviewed to identify predictors of survival and functional outcome. The authors retrospectively reviewed the records of all patients who were treated with surgery for prostate cancer metastases to the spine between 1993 and 2005 at a single institution. Particular attention was given to initial presentation, operative management, clinical and neurological outcomes, and factors associated with complications and overall survival. Forty-four patients underwent a total of 47 procedures. The median age at spinal metastasis was 66 years (range 50-84 years). Twenty-four patients had received previous external-beam radiation to the site of spinal involvement, with a median dose of 70 Gy (range 30-74 Gy). Frankel scores on discharge were significantly improved when compared with preoperative scores (p = 0.001). Preoperatively, 32 patients (73%) were walking and 33 (75%) were continent. On discharge, 36 (86%) of 42 patients were walking, and 37 (88%) of 42 were continent. Preoperatively, 40 patients (91%) were taking narcotics, with a median morphine equivalent dose of 21.5 mg/day, and 28 patients (64%) were taking steroids, with a median dose of 16 mg/day. At discharge, the median postoperative morphine equivalent dose was 12 mg/day, and the median steroid dose was 0 mg/day (p or = 65 years at the time of surgery was an independent predictor of a postoperative complication (p = 0.005). In selected patients with prostate cancer metastases to the spine, aggressive surgical decompression and spinal reconstruction is a useful treatment option. The results show that on average, neurological outcome is improved and use of analgesics

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

    Full Text Available Cronkhite-Canada syndrome is characterized by gastrointestinal and ectodermal manifestations. In this paper, we describe a 64-year-old Iranian male, presenting with Cronkhite-Canada syndrome with metastatic colon cancer. The patient was suffering from hair loss, which occurred on the scalp at first and then, during 5 months, extended to the whole body. After that, his sense of taste was impaired, and 2 months later, gastrointestinal symptoms gradually started, with weight loss of 20 kg over 2 months with an initial weight of 100 kg. Finally, he was admitted to our center 10 months after the onset of symptoms. On skin examination, generalized hair loss and hyperpigmentation and dysmorphic nail changes were observed. Multiple polyps within the colon and sigmoid were observed on colonoscopy. According to biopsies, a serrated adenoma and an invasive adenocarcinoma were reported in the ascending colon and sigmoid, respectively. Other polyps were pseudopolyps, and their characteristics were not significant. Computed tomography of the lungs and abdomen showed multiple adenopathies. On biopsy, metastatic adenocarcinoma was reported. The patient underwent chemotherapy with FOLFIRI and ERBITUX. Finally, after 5 courses of chemotherapy, his regimen was changed to FOLFOX and Avastin because of evidence of progression on computed tomography. The etiology of Cronkhite-Canada syndrome is currently unknown, and the optimal therapy has not been reported so far. This syndrome has many complications; the major of them is malignancy, and the prognosis is poor with a mortality rate of 50%. Therefore, annual monitoring is necessary in these patients.

    Most metastatic cancers after initial response to current drug therapies develop resistance to the treatment. We present cancer data and a theory that explains the observed kinetics of tumor growth in cancer patients and using a stochastic model based on this theory we relate the kinetics of tumor growth to Kaplan-Meyer survival curves. The theory points to the tumor growth rate as the most important parameter determining the outcome of a drug treatment. The overall tumor growth or decay rate is a reflection of the balance between cell division, senescence and apoptosis and we propose that the deviation of the decay rate from exponential is a measure of the emergence of drug resistance. In clinical trials the progression free survival, the overall survival, and the shape of the Kaplan-Meyer plots are determined by the tumor growth rate probability distribution among the patients in the trial. How drug treatments modify this distribution will also be described. At the end of the talk we will discuss the connection between the theory described here and the age related cancer mortality rates in the United States.

    Breast cancer is the most common cancer affecting women worldwide. It is a distressing diagnosis and, as a result, considerable research has examined the psychological sequelae of being diagnosed and treated for breast cancer. Breast cancer is associated with increased rates of depression and anxiety and reduced quality of life. As a consequence, multiple studies have explored the impact of psychological interventions on the psychological distress experienced after a diagnosis of breast cancer. To assess the effects of psychological interventions on psychological morbidities, quality of life and survival among women with non-metastatic breast cancer. We searched the following databases up to 16 May 2013: the Cochrane Breast Cancer Group Specialised Register, CENTRAL, MEDLINE, EMBASE, CINAHL and PsycINFO; and reference lists of articles. We also searched the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) search portal and ClinicalTrials.gov for ongoing trials in addition to handsearching. Randomised controlled trials that assessed the effectiveness of psychological interventions for non-metastatic breast cancer in women. Two review authors independently appraised and extracted data from eligible trials. Any disagreement was resolved by discussion. Extracted data included information about participants, methods, the intervention and outcome. Twenty-eight randomised controlled trials comprising 3940 participants were included. The most frequent reasons for exclusion were non-randomised trials and the inclusion of women with metastatic disease. A wide range of interventions were evaluated, with 24 trials investigating a cognitive behavioural therapy and four trials investigating psychotherapy compared to control. Pooled standardised mean differences (SMD) from baseline indicated less depression (SMD -1.01, 95% confidence interval (CI) -1.83 to -0.18; P = 0.02; 7 studies, 637 participants, I(2) = 95%, low quality evidence), anxiety

    Full Text Available Background. We examined overall and disease-free survivals in a cohort of patients subjected to resection of liver metastasis from colorectal cancer (CRLM in a 10-year period when new treatment strategies were implemented. Methods. Data from 239 consecutive patients selected for liver resection of CRLM during the period from 2002 to 2011 at a single center were used to estimate overall and disease-free survival. The results were assessed against new treatment strategies and established risk factors. Results. The 5-year cumulative overall and disease-free survivals were 46 and 24%. The overall survival was the same after reresection, independently of the number of prior resections and irrespectively of the location of the recurrent disease. The time intervals between each recurrence were similar (11 ± 1 months. Patients with high tumor load given neoadjuvant chemotherapy had comparable survival to those with less extensive disease without neoadjuvant chemotherapy. Positive resection margin or resectable extrahepatic disease did not affect overall survival. Conclusion. Our data support that one still, and perhaps to an even greater extent, should seek an aggressive therapeutic strategy to achieve resectable status for recurrent hepatic and extrahepatic metastases. The data should be viewed in the context of recent advances in the understanding of cancer biology and the metastatic process.

    Full Text Available Prostate-specific antigen (PSA is well known as a specific tumor marker for prostate cancer, but carcinoembryonic antigen (CEA- and carbohydrate antigen 19-9 (CA19-9-elevating adenocarcinomas originating in the prostate gland are rare. We report a case of metastatic adenocarcinoma of the prostate gland with a high serum level of CEA and CA19-9 in a 78-year-old man in whom prostate cancer (T3N1M1 had been diagnosed 2 years ago and who was treated with androgen deprivation therapy. He visited the emergency department because of a loss of appetite and abdominal pain. The serum CEA and CA19-9 levels were increased to 218.9 ng/mL (normal, <5 ng/mL and 212 ng/mL (normal, <27 ng/mL, respectively. The serum PSA level was slightly elevated (4.41 ng/mL. Computed tomography demonstrated multiple liver metastases, para-aortic lymph node enlargement, and lung metastases. A liver biopsy was performed and the specimen showed high-grade adenocarcinoma with focal positive staining for PSA. Despite chemotherapy with docetaxel, the patient died 3 months after treatment. Based on this case and a review of the literature, an aggressive variant of prostatic carcinoma with a high serum level of CEA and CA19-9 and a low PSA level was shown to progress rapidly with a poor prognosis.

We sought to (i) quantify tablet burden in women with metastatic breast cancer (MBC), (ii) establish which groups of drug contribute most to this burden and (iii) gain insight into patients' attitudes towards oral anti-cancer treatment. One hundred patients with MBC anonymously completed a questionnaire describing their medication histories and attitudes towards their tablets. The patients (mean age 60, range 31-95) were all female and taking a median of six tablets (range 0-31) daily; 37 patients were taking >10 tablets. Oral anticancer treatment constituted the category of treatment taken by the highest proportion of patients, followed by symptomatic cancer treatments, proton pump inhibitors and cardiovascular medication. Numerically, however, symptomatic drugs accounted for 44% of all tablets and specific anti-cancer treatment for 15%; medication not directly related to the cancer accounted for the remaining 40% of tablets. A quarter of patients reported inconvenience in taking their tablets, the main reason being tablet size and one third reported forgetting their tablets at least once a week. Nearly two thirds of patients expressing a preference favoured oral anticancer treatment, the commonest reason being greater convenience. Tablet burden is considerable for many patients with MBC and can be problematic. A significant proportion of tablets represent treatment for co-morbidities, the significance of which may be questionable in women with MBC. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Metastases to the spine can involve the bone, epidural space, leptomeninges, and spinal cord. The spine is the third most common site for metastatic disease, following the lung and the liver. Approximately 60–70% of patients with systemic cancer will have spinal metastasis. Materials/Methods. This is a review of the imaging techniques and typical imaging appearances of spinal metastatic disease. Conclusions. Awareness of the different manifestations of spinal metastatic disease is essential as the spine is the most common site of osseous metastatic disease. Imaging modalities have complimentary roles in the evaluation of spinal metastatic disease. CT best delineates osseous integrity, while MRI is better at assessing soft tissue involvement. Physiologic properties, particularly in treated disease, can be evaluated with other imaging modalities such as FDG PET and advanced MRI sequences. Imaging plays a fundamental role in not only diagnosis but also treatment planning of spinal metastatic disease.

    Liver resection is the preferred method of treatment of hepatic metastases. Unfortunately, only 10-20% of patients can be qualified for surgery. One of the alternative palliative methods of treatment is percutaneous alcoholisation of metastatic foci (PEIT). The treatment procedure is determined primarily by the progression of the process in the liver, assessed with non-invasive imaging techniques. Assessment of diagnostic value of MR for patients with focal changes in the liver, an attempt to establish the algorithm of diagnostic and therapeutic procedure, and determination of the criteria qualifying for PEIT. The patients (after USG and BAC) due for liver resection because of liver metastases were subjected to MRI performed with a GYROSCAN NT apparatus with 1T field using a 'body' type solenoid in T2-weighted sequences and STIR/LONG and T1-weighted ones, before and after intravenous administration of a contrast medium in arterial and venous phase, in transversal and frontal planes. MR examination changed the procedure of treatment as a result of larger number and size of metastatic foci found by MRI than by USG. The results of MR examination caused a decrease in the number of patients qualified for liver resection, with a rise in the number of patients referred for PEIT. The application of another diagnostic method (e.g. MR) after USG examination is necessary for patients due for liver resection. MR examination of the liver allows a precise assessment of the operability criteria of hepatic metastases and significantly influences the treatment procedure in patients with metastatic changes in the liver.

    Full Text Available Abstract Although about 30% of gastric cancers have distant metastasis at the time of initial diagnosis, metastatic tumor embolus in the main blood vessels is not common, especially in the main artery. The report presents, for the first time, an extremely rare clinical case of a metastatic embolus in the common carotid artery (CCA from primary gastric cancer. Metastatic embolus from the primary tumor should be considered when patients present with gastric cancer accompanied by intravascular emboli. The patient should be actively examined further so as to allow early detection and treatment.

  19. Virilisation during Pregnancy in a Patient with Metastatic Colorectal Cancer

    F. Conway

    2012-01-01

    Full Text Available This paper describes the case of a 25-year-old woman with virilisation occurring during pregnancy in the presence of metastatic colorectal cancer. Virilisation during pregnancy is rare. The potential causes include adrenal, foetal, or ovarian pathologies. The most common causes during pregnancy are pregnancy luteoma and hyperreactio luteinalis. The incidence of cancer during pregnancy is rare and the incidence of colorectal cancer (CRC in pregnancy is even rarer. The presenting signs and symptoms of CRC can be confused with symptoms commonly encountered during pregnancy, thereby delaying diagnosis and commencement of treatment. Diagnosis and staging also proves more problematic in the pregnant patient as the usual modalities of colonoscopy with biopsy and imaging with CT are relatively contraindicated. Treatment is dependent on gestational age of the foetus. There is currently no agreed best practice as to the role of prophylactic oophorectomy in the prevention of metachronous ovarian metastases. Surgical and adjuvant treatments have implications for females of child-bearing age.

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

    Forty patients with metastatic brain tumors from primary lung cancer underwent radiosurgery (γ-knife). We retrospectively compared their prior treatment history, number of metastatic foci, and performance status, to evaluate the effects of, and indications for, γ-knife therapy. After both the primary and the metastatic tumors were controlled, performance status could be used as an index in the choice of γ-knife therapy. Our results demonstrate that repeated γ-knife radiosurgeries prolonged survival time. Gamma-knife radiosurgery improves quality of life and prognosis of patients with metastatic brain tumors.

    Full Text Available Aims: The study was carried out to evaluate the early outcomes using Radiofrequency Ablation (RFA for unresectable liver metastases in the management of metastatic colorectal cancer (mCRC from an area of low endemicity. Material and Methods: 60 Patients with unresectable colorectal liver metastases had undergone 88 sessions of RFA from January 2007 till December 2013. The results were retrospectively analysed to evaluate the outcomes in terms of efficacy and survival rates. Results: The median follow up of patients in our series was 24.8months. 35/52 (67.3% patients had complete response at 3 months while 8 patients were lost to follow up. Of the 17 patients who had recurrence, 4 (23.5% were at the ablated site while 13 patients (76.4% progressed elsewhere. Abdominal pain was commonest post procedural symptom (20%. There was no procedure related mortality or any major complications. Mean disease free interval and Progression free survival was 6.7 and 13.1 months. Estimated median survival in patients with liver limited disease and those with small lesion (3 cm was associated with decreased survival.

    We measured the ex vivo electrical conductivity of eight human metastatic liver tumours and six normal liver tissue samples from six patients using the four electrode method over the frequency range 10 Hz to 1 MHz. In addition, in a single patient we measured the electrical conductivity before and after the thermal ablation of normal and tumour tissue. The average conductivity of tumour tissue was significantly higher than normal tissue over the entire frequency range (from 4.11 versus 0.75 mS cm(-1) at 10 Hz, to 5.33 versus 2.88 mS cm(-1) at 1 MHz). We found no significant correlation between tumour size and measured electrical conductivity. While before ablation tumour tissue had considerably higher conductivity than normal tissue, the two had similar conductivity throughout the frequency range after ablation. Tumour tissue conductivity changed by +25% and -7% at 10 Hz and 1 MHz after ablation (0.23-0.29 at 10 Hz, and 0.43-0.40 at 1 MHz), while normal tissue conductivity increased by +270% and +10% at 10 Hz and 1 MHz (0.09-0.32 at 10 Hz and 0.37-0.41 at 1 MHz). These data can potentially be used to differentiate tumour from normal tissue diagnostically.

    In Asia, up to 25% of breast cancer patients present with distant metastases at diagnosis. Given the heterogeneous survival probabilities of de novo metastatic breast cancer, individual outcome prediction is challenging. The aim of the study is to identify existing prognostic models for patients with de novo metastatic breast cancer and validate them in Asia. We performed a systematic review to identify prediction models for metastatic breast cancer. Models were validated in 642 women with de novo metastatic breast cancer registered between 2000 and 2010 in the Singapore Malaysia Hospital Based Breast Cancer Registry. Survival curves for low, intermediate and high-risk groups according to each prognostic score were compared by log-rank test and discrimination of the models was assessed by concordance statistic (C-statistic). We identified 16 prediction models, seven of which were for patients with brain metastases only. Performance status, estrogen receptor status, metastatic site(s) and disease-free interval were the most common predictors. We were able to validate nine prediction models. The capacity of the models to discriminate between poor and good survivors varied from poor to fair with C-statistics ranging from 0.50 (95% CI, 0.48-0.53) to 0.63 (95% CI, 0.60-0.66). The discriminatory performance of existing prediction models for de novo metastatic breast cancer in Asia is modest. Development of an Asian-specific prediction model is needed to improve prognostication and guide decision making.

    Metastatic breast cancer is a disease of changing status-once an imminent death sentence, now a chronic (albeit incurable) disease. Medical intervention advances mean women with metastatic breast cancer now have symptoms alleviated and, potentially, life extended. Living with this disease, however, requires more than a medical approach to symptoms. We were interested to know whether women manage, and if so, how, to "live well" with metastatic cancer. We conducted interviews with 18 women. Women differed in the approaches they used. Most common was the attempt to reestablish a sense of normality in their lives. However, a second group reevaluated and reprioritized their lives; and a third group was restricted in their capacity to live well because of symptoms. The findings provide the foundation for future research exploring normalization of experiences of metastatic cancer, and other chronic illnesses, where people are living with knowledge that they have contracted time. © The Author(s) 2015.

    2016-01-01

    Full Text Available Introduction. Combined use of bevacizumab and conventional anticancer drugs leads to a significant improvement of treatment response in patients with metastatic colorectal carcinoma (CRC. Conventional treatment protocols exert undesired effects on the liver tissue. Hepatotoxic effects are manifested as a disturbance of liver function test parameters. The relation between clinical outcome and disorder of biochemical parameters has not been completely evaluated. Objective. The objective of our study was to examine whether clinical outcome in patients with liver metastatic CRC correlates with the level of liver function test parameters. Methods. The study included 96 patients with untreated liver metastatic CRC who received FOLFOX4 protocol with or without bevacizumab. Biochemical liver parameters were performed before and after the treatment completion. Treatment response was evaluated as disease regression, stable disease, and disease progression. The patients were divided into three groups according to the accomplished treatment response. Results. In the group of patients with disease regression the post-treatment levels of aspartate aminotransferase, alanine aminotransferase, and bilirubin were statistically significantly increased. In contrast to this, gamma-glutamyltransferase and protein post-treatment values were significantly lower in relation to initial values. In patients with stable disease, difference was found only in the level of proteins being lower after the treatment. In patients with disease progression, values of aspartate aminotransferase and bilirubin were significantly increased after completed treatment. Conclusion. Treatment responses are not completely associated with the level of liver function test parameters. The only parameter which correlated with treatment response is gamma-glutamyltransferase. Its decrease is accompanied with disease regression.

    Breast cancer is diagnosed when it is already metastatic in about 6 per cent of cases. The author discusses comparative studies which showed that a surgical treatment of the primitive tumour resulted in a global survival benefit for the patients. As the role of radiotherapy in such a situation, either alone or with surgery, is not well documented, he intends to discuss the interest of radiotherapy within the frame of the local treatment of a straightaway metastatic breast cancer.

    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.

    Evaluation of the liver for focal lesions is extremely important because the liver is one of the most common sites for metastatic disease. Most patients with metastatic deposits to the liver have a survival rate of about 6 months. Thus, metastatic disease to the liver has an extremely grave prognosis. In the past patients with hepatic lesions had no therapeutic recourse. However, with recent aggressive surgical advances (such as partial hepatectomies) and hepatic artery embolization, survival of patients with hepatic metastases has increased. Thus it is important for noninvasive imaging not only to detect lesions early in their course, but also to give their true hepatic involvement and the extent of the neoplastic process elsewhere in the body. Recent advances in imaging have been rapidly changing over the past 5 years. These changes have been more rapid in computed tomography (CT) and ultrasound than in radionuclide imaging. Thus, the question addressed in this chapter is: What is the relationship of hepatic ultrasound to the other current diagnostic modalities in detecting metastatic liver disease and other focal liver lesions? Also, what is its possible future relationship to nuclear magnetic resonance?

    Full Text Available Abstract Background Bevacizumab (BEV plus triplet chemotherapy can increase efficacy of first-line treatment of metastatic colorectal cancer (MCRC, particularly integrated with secondary liver surgery in liver-limited (L-L patients. The prognostic value of the KRAS genotype in L-L and other or multiple metastatic (O/MM MCRC patients treated with the FIr-B/FOx regimen was retrospectively evaluated. Methods Tumoral and metastatic samples were screened for KRAS codon 12 and 13 and BRAF mutations by SNaPshot and/or direct sequencing. Fit MCRC patients 2, days 1, 2, 8, 9, 15, 16, 22 and 23; irinotecan (CPT-11 160 mg/m2 plus BEV 5 mg/kg, days 1, 15; oxaliplatin (OXP 80 mg/m2, days 8, 22; every 4 weeks. MCRC patients were classified as L-L and O/MM. Activity and efficacy were evaluated and compared using log-rank test. Results In all, 59 patients were evaluated: 31 KRAS wild-type (53%, 28 KRAS mutant (47%. At 21.5 months median follow-up, objective response rate (ORR, progression-free survival (PFS and overall survival (OS were, respectively: KRAS wild-type 90%, 14 months, 38 months; KRAS mutant 67%, 11 months, 20 months. PFS and OS were not significantly different. PFS and OS were significantly different in L-L compared to O/MM evaluable patients. In KRAS wild-type patients, clinical outcome of 12 L-L compared to 18 O/MM was significantly different: PFS 21 versus 12 months and OS 47 versus 28 months, respectively. In KRAS mutant patients, the clinical outcome of 13 L-L compared to 14 O/MM was not significantly different: PFS 11 months equivalently and OS 39 versus 19 months, respectively. Conclusions The KRAS genotype wild-type and mutant does not significantly affect different clinical outcomes for MCRC patients treated with the first-line FIr-B/FOx intensive regimen. KRAS wild-type patients with L-L disease may achieve a significantly prolonged clinical outcome due to integration with secondary liver surgery, with respect to KRAS mutant patients.

    Improved survival for individuals with metastatic cancer accentuates the importance of employment for cancer survivors. A better understanding of how metastatic cancer affects employment is a necessary step toward the development of tools for assisting survivors in this important realm. The ECOG-ACRIN Symptom Outcomes and Practice Patterns study was analyzed to investigate what factors were associated with the employment of 680 metastatic cancer patients. Univariate and multivariate logistic regression analyses were conducted to compare patients stably working with patients no longer working. There were 668 metastatic working-age participants in the analysis: 236 (35%) worked full- or part-time, whereas 302 (45%) had stopped working because of illness. Overall, 58% reported some change in employment due to illness. A better performance status and non-Hispanic white ethnicity/race were significantly associated with continuing to work despite a metastatic cancer diagnosis in the multivariate analysis. The disease type, time since metastatic diagnosis, number of metastatic sites, location of metastatic disease, and treatment status had no significant impact. Among the potentially modifiable factors, receiving hormonal treatment (if a viable option) and decreasing symptom interference were associated with continuing to work. A significant percentage of the metastatic patients remained employed; increased symptom burden was associated with a change to no longer working. Modifiable factors resulting in work interference should be minimized so that patients with metastatic disease may continue working if this is desired. Improvements in symptom control and strategies developed to help address workplace difficulties have promise for improving this aspect of survivorship. © 2015 American Cancer Society.

    Liver cancer is one of the most common malignancies of the digestive system. Minimally invasive ablation procedures have become one of the major means for treating unresectable multifocal liver cancer and have been extensively applied in primary and metastatic liver cancer treatment. Laparoscopic B-ultrasound-guided microwave ablation is an example of the progress made in this field. To analyze and summarize the results of and experience with laparoscopic B-ultrasound-guided microwave ablation for multifocal primary liver cancer; moreover, the ablation effects were compared between tumors of different sizes. Laparoscope-guided needle ablation was conducted on 84 lesions from 32 patients with primary liver cancer based on tumor size, quantity, and location. Moreover, the perioperative data, ablation effects according to tumor size, and long-term follow-up results were analyzed. Among the 84 nodules treated via microwave ablation, tumors measuring ≤ 3 cm demonstrated complete ablation upon imaging analysis conducted 1 month after surgery. Moreover, 5 of the tumors measuring > 3 cm demonstrated incomplete ablation. In these cases, a second procedure was performed, until imaging studies confirmed that complete ablation was achieved. Laparoscopic microwave ablation allows for precise puncture positioning, an effective ablation range, and safe and feasible surgery, which is especially suitable for liver tumors located in sites difficult to access.

    Lung cancer (LC) is the most common cause of death associated with neoplasms. The incidence of LC in 2007 was 71.3/100,000 men and 18.6/100,000 women in Slovakia. Small-cell lung cancer (SCLC) includes 15 - 18% of all cases. The diagnosis of LC is based on patient's history, physical examination, basic laboratory tests, x-ray imaging and computed tomography (CT) imaging and histology. The material required for histology can be obtained by means of endoscopy or surgery. Ultrasonography (USG) and/or CT of abdomen is commonly performed as a part of staging process, along with CT or MRI of brain. Bone scan is performed in case of suspicion of bone involvement. According to TNM classification, seventh edition, the same classification can be used for SCLC and non-small cell lung cancer (NSCLC). Chemotherapy and radiotherapy are available for treatment of initially metastatic SCLC. First-line chemotherapy regimen should be based on combination of cisplatin or carboplatin with etoposide (PE). Alternatively, CAV regimen (cyclophosphamide, doxorubicin, vincristine) can be used. Newer regimens did not provide benefit when compared to standard regimens. If progression occurs later than 3 months after finishing first-line chemotherapy, the same regimen may be used in second-line chemotherapy. If progression occurs earlier than 3 months after finishing first-line chemotherapy, topotecan-based regimen is an option for second-line line chemotherapy. Despite promising outcomes of amrubicin-based second-line chemotherapy in Japan, amrubicin is not available in countries of E U. Standard therapy schedules do not include radiotherapy targeted on primary tumor and affected lymph-nodes. According to American and European guidelines, prophylactic cranial irradiation is recommended for patients with extensive disease-SCLC with good performance status after achieving complete or partial response to first-line chemotherapy.

    The purpose of this study was to investigate the effect of proton beam on enzymes for promotion/progression of carcinogenesis and metastasis of malignant tumor cells to clarify proton beam-specific biological effects. The changes of cancer chemopreventive enzymes in human colorectal adenocarcinoma HT-29 cells irradiated with proton beams were tested by measuring the activities of quinine reductase (QR), glutathione S-transferase (GST), and ornithine decarboxylase (ODC), glutathione (GSH) levels, and expression of cyclooxygenase-2 (COX-2). We also examined the effect of proton beam on the ODC activity and expression of COX-2 in human breast cancer cell. We then assessed the metastatic capabilities of HT-29 and MDA-MB-231 cells irradiated with proton beam by measuring the invasiveness of cells through Matrigel-coated membrane and 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced MMP activity in MDA-MB-231 and HT-29 cells. QR activity of irradiated HT-29 cells was slightly increased. Proton irradiation at dose of 32 Gy in HT-29 cells increased GST activity by 1.23-fold. In addition GSH levels in HT-29 cells was significantly increased 1.23- (p<0.05), 1.32- (p<0.01) and 1.34-fold (p<0.01) with the proton irradiation at doses of 8, 16 and 32 Gy, respectively. These results suggest that colon cancer chemopreventive activity was increased with the proton irradiation by increasing QR and GST activities and GSH levels and inhibiting ODC activity. Proton ion irradiation decreased the invasiveness of TPA-treated HT-29 cells and MDA-MB-231 cells through Matrigel-coated membrane. Proton ion irradiation pretreatment decreased TPA-induced MMP activity in MDA-MB-231 and HT-29 cells. Further studies are necessary to investigate if these findings could be translated to in vivo situations

    Patient characteristics and stratification factors are key features influencing trial outcomes. However, there is substantial heterogeneity in reporting of patient characteristics and use of stratification factors in phase 3 trials investigating systemic treatment of metastatic colorectal cancer (mCRC). We aimed to develop a minimum set of essential baseline characteristics and stratification factors to include in such trials. We performed a modified, two-round Delphi survey among international experts with wide experience in the conduct and methodology of phase 3 trials of systemic treatment of mCRC. Thirty mCRC experts from 15 different countries completed both consensus rounds. A total of 14 patient characteristics were included in the recommended set: age, performance status, primary tumour location, primary tumour resection, prior chemotherapy, number of metastatic sites, liver-only disease, liver involvement, surgical resection of metastases, synchronous versus metachronous metastases, (K)RAS and BRAF mutation status, microsatellite instability/mismatch repair status and number of prior treatment lines. A total of five patient characteristics were considered the most relevant stratification factors: RAS/BRAF mutation status, performance status, primary tumour sidedness and liver-only disease. This survey provides a minimum set of essential baseline patient characteristics and stratification factors to include in phase 3 trials of systemic treatment of mCRC. Inclusion of these patient characteristics and strata in study protocols and final study reports will improve interpretation of trial results and facilitate cross-study comparisons.

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

    Full Text Available Patients with breast cancer along with metastatic estrogen and progesterone receptor (ER/PR- and human epidermal growth factor receptor 2 (HER2-negative tumors are referred to as having metastatic triple-negative breast cancer (mTNBC disease. Resistance to current standard therapies such as anthracyclines or taxanes limits the available options for previously treated patients with metastatic TNBC to a small number of non-cross-resistant regimens, and there is currently no preferred standard chemotherapy. Clinical experience suggests that many women with triple-negative metastatic breast cancer (MBC relapse quickly. Expert oncologist discussed about new chemotherapeutic strategies and agents used in treatment of mTNBC and the expert group used data from published literature, practical experience and opinion of a large group of academic oncologists to arrive at this practical consensus recommendations for the benefit of community oncologists.

    Background Improved survival for individuals with metastatic cancer accentuates the importance of employment for cancer survivors. Better understanding of how metastatic cancer affects employment is a necessary step towards the development of tools to assist survivors in this important realm. Methods We analyzed the Eastern Cooperative Oncology Group’s “Symptom Outcomes and Practice Patterns (SOAPP)” study to investigate what factors were associated with employment of 680 metastatic cancer patients. Univariable and multivariable logistic regression analyses were conducted to compare patients stably working (Group A) to patients no longer working (Group B). Results There were 668 metastatic working-age participants in our analysis; 236 (35%) worked full or part-time while 302 (45%) stopped working due to illness. Overall, 58% reported some change in employment due to illness. Better performance status and non-Hispanic White ethnicity/race were significantly associated with continuing to work despite a metastatic cancer diagnosis on multivariable analysis. Disease type, time since metastatic diagnosis, number of metastatic sites, location of metastatic disease, and treatment status had no significant impact. Among the potentially modifiable factors, receiving hormonal treatment (if a viable option) and decreasing symptom interference were associated with continuing to work. Conclusions A significant percentage of metastatic patients remain employed; symptom burden was associated with change to no longer working. Modifiable factors resulting in work interference should be minimized so that patients with metastatic disease may continue working, if desired. Improvements in symptom control and strategies developed to help address work place difficulties have promise to improve this aspect of survivorship. PMID:26687819

    Breast cancer is the most common causes of women’s death in the world. Metastatic spread presents a major clinical problem in about 30% of the patients. The study aims to investigate the clinical reliability of mammaglobin mRNA as a marker of circulating cancer cells in breast cancer patients. The positivity of blood was analyzed in relation to clinical and pathological characteristics. This study was on 29 breast cancer patients (13 metastatic, 16 non- metastatic patients), where28 were invasive intraductal carcinoma type and 1 was invasive lobular carcinoma type. Breast cancer patients were according to the histologic grade into grade I (7 patients),grade II (6 patients) and grade III (15 patients). All individuals included in this study were subjected to detection of mammaglobin m-RNA of circulating tumor cells in peripheral blood using RT-PCR technique. Positivity for mammaglobin in blood samples was in 38% of patients with metastatic but not in the non-metastatic patients. The presence of mammaglobin correlated with metastatic tumor (P = 0.011). Mammaglobin overexpression in breast tissue was significantly positive in low-grade tumors (I and II).

    Prostate cancer is characterized by heterogeneity in the clinical course that often does not correlate with morphologic features of the tumor. Metastasis reflects the most adverse outcome of prostate cancer, and to date there are no reliable morphologic features or serum biomarkers that can reliably predict which patients are at higher risk of developing metastatic disease. Understanding the differences in the biology of metastatic and organ confined primary tumors is essential for developing new prognostic markers and therapeutic targets. Using Affymetrix oligonucleotide arrays, we analyzed gene expression profiles of 24 androgen-ablation resistant metastatic samples obtained from 4 patients and a previously published dataset of 64 primary prostate tumor samples. Differential gene expression was analyzed after removing potentially uninformative stromal genes, addressing the differences in cellular content between primary and metastatic tumors. The metastatic samples are highly heterogenous in expression; however, differential expression analysis shows that 415 genes are upregulated and 364 genes are downregulated at least 2 fold in every patient with metastasis. The expression profile of metastatic samples reveals changes in expression of a unique set of genes representing both the androgen ablation related pathways and other metastasis related gene networks such as cell adhesion, bone remodelling and cell cycle. The differentially expressed genes include metabolic enzymes, transcription factors such as Forkhead Box M1 (FoxM1) and cell adhesion molecules such as Osteopontin (SPP1). We hypothesize that these genes have a role in the biology of metastatic disease and that they represent potential therapeutic targets for prostate cancer

    Ixabepilone is currently FDA-approved in metastatic breast cancer, and most patients in the registrational trials were Caucasian. Studies in Asian populations receiving other cytotoxic agents have revealed differential pharmacokinetics and clinical outcomes. As such, clinicians should understand the possible contributions of Asian ethnicity and culture to the clinical profile of ixabepilone. Studies in Asian patients receiving other chemotherapeutics reported altered toxicity profiles for myelosuppression, neurotoxicity and gastrointestinal symptoms. Encouragingly, the limited clinical data in Asian patients receiving ixabepilone suggest that efficacy and toxicity in these women resemble those reported in the ixabepilone registrational trials. The reader will better understand how Asian genetics and culture may influence treatment outcomes and patient attitudes toward therapy and interaction with caregivers. Management of ixabepilone-related adverse events is also discussed with an emphasis on special considerations for Asian patients. Awareness of possible altered drug response in Asian patients will aid clinicians in monitoring for toxicity, recognizing the need for dose modification and educating patients. Sensitivity to cultural aspects that are unique to Asians may improve adherence, reporting of adverse events and trust among Asian patients receiving ixabepilone.

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

    2008-07-01

    Full Text Available Abstract Introduction We present the case of a patient with colon cancer who, while receiving bevacizumab, developed sinusoidal obstruction syndrome (veno-occlusive disease (SOSVOD. Certain antitumour agents such as 6-mercaptopurine and 6-thioguanine have also been reported to initiate hepatic SOSVOD in isolated cases. There have been no reports so far correlating bevacizumab with SOSVOD. Case presentation A 77-year-old man was being treated with oxaliplatin and a modified de Gramont regimen of 5-fluorouracil for metastatic colon cancer. Bevacizumab (7.5 mg/kg was added from the seventh cycle onwards. Protracted neutropenia and thrombocytopenia led to discontinuation of oxaliplatin after the ninth cycle. A computed tomography scan showed complete response and bevacizumab was continued for another 3 months, after which time the patient developed right hypochondrial pain, transudative ascites, splenomegaly and abnormal liver function tests. Upper gastrointestinal endoscopy showed oesophageal varices. Liver biopsy showed features considered to be consistent with SOSVOD. Bevacizumab was stopped and a policy of watchful waiting was adopted. He tolerated the acute damage to his liver and subsequently the ascites resolved and liver function tests normalised. Conclusion We need to be aware that bevacizumab can cause sinusoidal obstruction syndrome (veno-occlusive disease and that the occurrence of ascites should not be attributed to progressive disease without appropriate evaluation.

    Given the bone tropism of prostate cancer, conventional imaging modalities poorly identify or quantify metastatic disease. 89 Zr-huJ591 positron emission tomography (PET) imaging was performed in patients with metastatic prostate cancer to analyze and validate this as an imaging biomarker for metastatic disease. The purpose of this initial study was to assess safety, biodistribution, normal organ dosimetry, and optimal imaging time post-injection for lesion detection. Ten patients with metastatic prostate cancer received 5 mCi of 89 Zr-huJ591. Four whole-body scans with multiple whole-body count rate measurements and serum activity concentration measurements were obtained in all patients. Biodistribution, clearance, and lesion uptake by 89 Zr-huJ591 immuno-PET imaging was analyzed and dosimetry was estimated using MIRD techniques. Initial assessment of lesion targeting of 89 Zr-huJ591 was done. Optimal time for imaging post-injection was determined. The dose was well tolerated with mild chills and rigors seen in two patients. The clearance of 89 Zr-huJ591 from serum was bi-exponential with biological half-lives of 7 ± 4.5 h (range 1.1-14 h) and 62 ± 13 h (range 51-89 h) for initial rapid and later slow phase. Whole-body biological clearance was 219 ± 48 h (range 153-317 h). The mean whole-body and liver residence time was 78.7 and 25.6 h, respectively. Dosimetric estimates to critical organs included liver 7.7 ± 1.5 cGy/mCi, renal cortex 3.5 ± 0.4 cGy/mCi, and bone marrow 1.2 ± 0.2 cGy/mCi. Optimal time for patient imaging after injection was 7 ± 1 days. Lesion targeting of bone or soft tissue was seen in all patients. Biopsies were performed in 8 patients for a total 12 lesions, all of which were histologically confirmed as metastatic prostate cancer. One biopsy-proven lesion was not positive on 89 Zr-huJ591, while the remaining 11 lesions were 89 Zr-huJ591 positive. Two biopsy-positive nodal lesions were noted only on 89 Zr-huJ591 study, while the

    This study investigated interactive effects of CYP2B6 genotypes and liver metastasis on the prognosis of metastatic breast cancer patients who received combined chemotherapy of docetaxel and thiotepa. Totally 153 patients were retrospectively genotyped rs8192719 (c.1294 + 53C > T) and rs2279343 (c.785A > G). Kaplan-Meier method and Cox Proportional Hazard Regression model were used to estimate the survival. Patients with liver metastasis had worsen prognosis, conferring a 2.26-fold high risk of progression and 1.93-fold high risk of death (p T) and AG genotype of rs2279343 (c.785A > G) prolonged survival (p G) was associated with a 47% reduced risk of death and a 6-month-longer overall survival (p T) were 0.45 for progression and 0.40 for death; and the corresponding survival was improved by 6 months and 16 months, respectively (p < 0.05). Genotypes of CYP2B6 had an interaction with clinical efficacy of docetaxel and thiotepa on metastatic breast cancer patients; and metastatic sites also affected clinical responses. Further therapies should take into account of chemotherapy regimen, genotypes of metabolizing enzymes and metastatic sites for the particular subpopulation.

    We previously developed and characterized a highly invasive and metastatic triple-negative breast cancer (TNBC) variant by serial orthotopic implantation of MDA-MB-231 human breast cancer cells in nude mice. Eventually, a highly invasive and metastatic variant of human TNBC was isolated after lymph node metastases was harvested and orthotopically re-implanted into the mammary gland of nude mice for two cycles. The variant thereby isolated is highly invasive in the mammary gland and metastasized to lymph nodes in 10 of 12 mice compared to 2 of 12 of the parental cell line. In the present report, we observed that high-metastatic MDA-MB-231H-RFP cells produced significantly larger subcutaneous tumors compared with parental MDA-MB-231 cells in nude mice. Extensive lymphatic trafficking by high-metastatic MDA-MB-231 cells was also observed. High-metastatic MDA-MB-231 developed larger recurrent tumors 2 weeks after tumor resection compared with tumors that were not resected in orthotopic models. Surgical resection of the MDA-MB-231 high-metastatic variant primary tumor in orthotopic models also resulted in rapid and enhanced lymphatic trafficking of residual cancer cells and extensive lymph node and lung metastasis that did not occur in the non-surgical mice. These results suggest that surgical resection of high metastatic TNBC can greatly increase the malignancy of residual cancer. J. Cell.

    The therapeutic management of people with metastatic colorectal cancer (CRC) who did not respond to first-line treatment represents a formidable challenge. To determine the efficacy and toxicity of second-line systemic therapy in people with metastatic CRC. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library 2016, Issue 4), Ovid MEDLINE (1950 to May 2016), Ovid MEDLINE In-process & Other Non-Indexed Citations (1946 to May 2016) and Ovid Embase (1974 to May 2016). There were no language or date of publication restrictions. Randomized controlled trials (RCTs) assessing the efficacy (survival, tumour response) and toxicity (incidence of severe adverse effects (SAEs)) of second-line systemic therapy (single or combined treatment with any anticancer drug, at any dose and number of cycles) in people with metastatic CRC that progressed, recurred or did not respond to first-line systemic therapy. Authors performed a descriptive analysis of each included RCT in terms of primary (survival) and secondary (tumour response, toxicity) endpoints. In the light of the variety of drug regimens tested in the included trials, we could carry out meta-analysis considering classes of (rather than single) anticancer regimens; to this aim, we applied the random-effects model to pool the data. We used hazard ratios (HRs) and risk ratios (RRs) to describe the strength of the association for survival (overall (OS) and progression-free survival (PFS)) and dichotomous (overall response rate (ORR) and SAE rate) data, respectively, with 95% confidence intervals (CI). Thirty-four RCTs (enrolling 13,787 participants) fulfilled the eligibility criteria. Available evidence enabled us to address multiple clinical issues regarding the survival effects of second-line systemic therapy of people with metastatic CRC.1. Chemotherapy (irinotecan) was more effective than best supportive care (HR for OS: 0.58, 95% CI 0.43 to 0.80; 1 RCT; moderate-quality evidence); 2

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

    Prostate cancer is one of the most common malignant neoplastic diseases in men. Early control of the disease progression contributes significantly to survival rates and patients' quality of life. Osteoprotegerin is a dimeric glycoprotein, which affects bone metabolism and inhibits osteoclastogenesis. In the present study, we evaluated the expression of osteoprotegerin in the serum of prostate cancer patients with or without skeletal metastases. The expression of serum osteoprotegerin, as measured by enzyme-linked immunosorbent assay, has been studied in 82 patients with locally controlled prostate cancer, in 49 patients with metastatic bone disease and in a control group of 41 healthy males. At sampling time 65/131 of included patients were newly diagnosed, while 66/131 patients were already under hormonal therapy. All eligible prostate cancer patients had histologically confirmed malignancy. Serum total prostate-specific antigen (PSA) was determined by an immunoradiometric assay. We investigated the expression of osteoprotegerin in hormone-dependent and hormone-refractory prostate cancer and its relation to disease progression. Among the 131 patients with prostate cancer, higher osteoprotegerin and PSA concentrations have been observed in metastatic bone patients' sera (p cancer patients has shown a statistically significant area curve (p cancer patients (p cancer reflect the bone metastatic extent and may potentially be used in metastatic patients' follow-ups.

    Sixty-eight cases of liver cancer, 48 cases of hepatocellular carcinoma and 20 cases of metastatic liver cancer, were treated by injection of SMANCS-Lipiodol (S-L) via tumor feeding arteries. Abdominal CT was carried out on the 3 rd day, 1 week, 2 and 4 weeks after the administration. These CT images were compared with those before the administration. Both primary and metastatic liver cancers were visualized as high density area due to the selective stay of S-L. Thus, the method became useful as a diagnostic tool; several tumors were newly visualized after the administration. S-L stayed in primary tumors and metastatic tumors. There were three types of the remaining of S-L in metastatic tumors for a long period: Type A, in which S-L remained in entire tumors; Types B, in which it remained primarily in circumference of tumor and Mixed type of A and B. The anticancer effect of S-L paralleled with the extent of the remaining of S-L in tumors, which was classified from Grade 0 to Grade IV. Grade IV means that S-L was recognized in the entire areas of tumors in the every slice of CT, and in the Grade IV tumors size reduced effectively after several months period. The dosage which was necessary to attain Grade IV was 0.08 ml per square centimeters calculated by the largest slice of every tumor. From Grade 0 to III, they need additional administration of S-L until to attain Grade IV in the tumor for the effective tumor regression.

    Full Text Available Knee pain is a common reason for a patient to seek medical evaluation. Of the many causes of knee pain, malignancy is one of the least common. When malignancy is the etiology of the pain, it is usually due to a primary tumor of the osseous structures or soft tissues of the knee joint. Metastatic disease involving the knee joint is uncommon, with few cases reported in the literature. Of these reported cases, metastatic colon cancer is exceedingly rare. However, in a patient with new onset knee pain and the proper clinical history, metastatic disease should be considered as a potential explanation of symptoms. We report a case of knee pain and swelling due to metastatic colon cancer to the patella.

    Full Text Available INTRODUCTION: Abnormal cancer metabolism creates a glycolytic-dependency which can be exploited by lowering glucose availability to the tumor. The ketogenic diet (KD is a low carbohydrate, high fat diet which decreases blood glucose and elevates blood ketones and has been shown to slow cancer progression in animals and humans. Abnormal tumor vasculature creates hypoxic pockets which promote cancer progression and further increase the glycolytic-dependency of cancers. Hyperbaric oxygen therapy (HBO₂T saturates tumors with oxygen, reversing the cancer promoting effects of tumor hypoxia. Since these non-toxic therapies exploit overlapping metabolic deficiencies of cancer, we tested their combined effects on cancer progression in a natural model of metastatic disease. METHODS: We used the firefly luciferase-tagged VM-M3 mouse model of metastatic cancer to compare tumor progression and survival in mice fed standard or KD ad libitum with or without HBO₂T (2.5 ATM absolute, 90 min, 3x/week. Tumor growth was monitored by in vivo bioluminescent imaging. RESULTS: KD alone significantly decreased blood glucose, slowed tumor growth, and increased mean survival time by 56.7% in mice with systemic metastatic cancer. While HBO₂T alone did not influence cancer progression, combining the KD with HBO₂T elicited a significant decrease in blood glucose, tumor growth rate, and 77.9% increase in mean survival time compared to controls. CONCLUSIONS: KD and HBO₂T produce significant anti-cancer effects when combined in a natural model of systemic metastatic cancer. Our evidence suggests that these therapies should be further investigated as potential non-toxic treatments or adjuvant therapies to standard care for patients with systemic metastatic disease.

    Albumin nanoparticles are well-known as effective drug carriers used to deliver hydrophobic chemotherapeutic agents. Albumin nanoparticles encapsulating curcumin and doxorubicin were fabricated using slightly modified nanoparticle albumin-bound (nab™) technology, and the synergistic effects of these two drugs were examined. Albumin nanoparticles encapsulating curcumin, doxorubicin, and both curcumin and doxorubicin were prepared using a high pressure homogenizer. The sizes of albumin nanoparticles were ∼130nm, which was considered to be suitable for the EPR (enhanced permeability and retention) effect. Albumin nanoparticles gradually released drugs over a period of 24h without burst effect. To confirm the synergistic effect of two drugs, in vitro cytotoxicity assay was performed using B16F10 melanoma cells. The cytotoxic effect on B16F10 melanoma cells was highest when co-treated with both curcumin and doxorubicin compared to single treatment of either curcumin and doxorubicin. The combined index calculated by medium-effect equation was 0.6069, indicating a synergistic effect. Results of confocal laser scanning microscopy and fluorescence-activated cell sorting corresponded to results from an in vitro cytotoxicity assay, indicating synergistic cytotoxicity induced by both drugs. A C57BL/6 mouse model induced by B16F10 lung metastasis was used to study in vivo therapeutic effects. When curcumin and doxorubicin were simultaneously treated, the metastatic melanoma mass in the lungs macroscopically decreased compared to curcumin or doxorubicin alone. Albumin nanoparticles encapsulating two anticancer drugs were shown to have an effective therapeutic result and would be an excellent way to treat resistant lung cancers.

    Full Text Available Metastatic breast cancer is a very heterogeneous disease, both from a clinical and a biological point of view. Despite being still incurable, the expanding therapeutic repertoire has determined a progressive increase in median survival. We describe the clinical course of a 67-year-old woman with a locally advanced, hormone-receptor positive breast cancer with synchronous liver metastases. Single-agent docetaxel at the dose of 100 mg/m2 for 8 cycles determined a pathological complete remission in the breast and a near complete remission of liver metastases. After more than 4 years from diagnosis, the patient is alive and without signs of tumour progression. Based on this clinical case, we discuss management issues like the choice of the initial treatment, the use of monochemotherapy vs polychemotherapy, the worth of surgery of the primary tumour in patients with stage IV disease, and the issue of maintenance endocrine therapy. Furthermore, we reviewed the pivotal role of docetaxel in the management of advanced breast cancer. Whether monochemotherapy or polychemotherapy is felt to be an adequate choice in the clinical practice, docetaxel qualifies as one of the most active and manageable agents. Single agent activity ranging from 20-48% in terms of response rate has been reported in several clinical trials in patients treated in various clinical settings. Docetaxel-based combinations with other cytotoxic agents have become established in the first line treatment both in patients with anthracycline-resistant and anthracycline-sensitive metastatic breast cancer. Finally, docetaxel has been shown to be an optimal companion drug for biologically targeted agents like trastuzumab or bevacizumab, resulting in further treatment options.

    Full Text Available Loco-regional therapy, which uses imaging technologies to facilitate targeted delivery of therapeutic agents to cancers, has emerged as the most commonly used non-surgical treatment for primary liver cancer. Since the theory of loco-regional therapy was introduced, various strategies have been developed and successfully applied in clinic, including interventional radiology methods (mainly transarterial chemoembolization and local ablative methods (such as intratumoral ethanol injection, radiofrequency ablation, microwave coagulation, laser-induced thermal therapy, high-intensity focused ultrasound, and cryotherapy. TACE has been widely applied to treat inoperable liver cancers at intermediate and advanced stages, while the local ablative therapies have proven more suitable for small (<5 cm liver cancers. However, choosing the appropriate loco-regional therapy strategy should be carried out on an individual basis, considering the patient's particular disease condition and characteristics. To help guide such treatment decisions, this review highlights the principal indications, theory, techniques, and reported efficacies of the various loco-regional therapy strategies.

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

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

    B16 melanoma (B16M) cells with high glutathione (GSH) content show rapid proliferation in vitro and high metastatic activity in the liver in vivo. gamma-Glutamyl transpeptidase (GGT)-mediated extracellular GSH cleavage and intracellular GSH synthesis were studied in vitro in B16M cells with high (F10) and low (F1) metastatic potential. GGT activity was modified by transfection with the human GGT gene (B16MF1/Tet-GGT cells) or by acivicin-induced inhibition. B16MF1/Tet-GGT and B16MF10 cells exhibited higher GSH content (35 +/- 6 and 40 +/- 5 nmol/10(6) cells, respectively) and GGT activity (89 +/- 9 and 37 +/- 7 mU/10(6) cells, respectively) as compared (P <.05) with B16MF1 cells (10 +/- 3 nmol GSH and 4 mU GGT/10(6) cells). Metastasis (number of foci/100 mm(3) of liver) increased in B16MF1 cells pretreated with GSH ester ( approximately 3-fold, P <.01), and decreased in B16MF1/Tet-GGT and B16MF10 cells pretreated with the GSH synthesis inhibitor L-buthionine (S,R)-sulphoximine ( approximately 5-fold and 2-fold, respectively, P <.01). Liver, kidney, brain, lung, and erythrocyte GSH content in B16MF1/Tet-GGT- or B16MF10-bearing mice decreased as compared with B16MF1- and non-tumor-bearing mice. Organic anion transporting polypeptide 1-independent sinusoidal GSH efflux from hepatocytes increased in B16MF1/Tet-GGT- or B16MF10-bearing mice ( approximately 2-fold, P <.01) as compared with non-tumor-bearing mice. Our results indicate that tumor GGT activity and an intertissue flow of GSH can regulate GSH content of melanoma cells and their metastatic growth in the liver.

    The aim of the present study was to review a single hepatobiliary center experience, the benefit of hepatic metastasectomy in breast cancer liver metastases (BCLM) patients and to identify predictors of survival. Fifty-two female patients underwent surgery for BCLM between 2002 and 2013. Only patients with liver resections (n=43) were included in the analysis. The median survival of the 43 patients with liver resection was 32.2 months. The factors significantly associated with overall post-hepatectomy survival were estrogen/progesteron receptor (ER/PR) status (p=0.002), node involvement of the primary tumor (p=0.049), size (p=0.005) and number (p=0.006) of the metastatic lesions. The 1-, 3- and 5-year survival rates after curative liver resection were 93.02%, 74.42%, 58.14%, respectively. BCLM resection is a safe procedure and offers survival benefit, especially in patients with reduced liver metastatic burden (solitary metastases, diameter of the metastases <5 cm) and positive ER/PR status.

  14. Predicting survival of de novo metastatic breast cancer in Asian women: systematic review and validation study.

    Directory of Open Access Journals (Sweden)

    Hui Miao

    Full Text Available BACKGROUND: In Asia, up to 25% of breast cancer patients present with distant metastases at diagnosis. Given the heterogeneous survival probabilities of de novo metastatic breast cancer, individual outcome prediction is challenging. The aim of the study is to identify existing prognostic models for patients with de novo metastatic breast cancer and validate them in Asia. MATERIALS AND METHODS: We performed a systematic review to identify prediction models for metastatic breast cancer. Models were validated in 642 women with de novo metastatic breast cancer registered between 2000 and 2010 in the Singapore Malaysia Hospital Based Breast Cancer Registry. Survival curves for low, intermediate and high-risk groups according to each prognostic score were compared by log-rank test and discrimination of the models was assessed by concordance statistic (C-statistic. RESULTS: We identified 16 prediction models, seven of which were for patients with brain metastases only. Performance status, estrogen receptor status, metastatic site(s and disease-free interval were the most common predictors. We were able to validate nine prediction models. The capacity of the models to discriminate between poor and good survivors varied from poor to fair with C-statistics ranging from 0.50 (95% CI, 0.48-0.53 to 0.63 (95% CI, 0.60-0.66. CONCLUSION: The discriminatory performance of existing prediction models for de novo metastatic breast cancer in Asia is modest. Development of an Asian-specific prediction model is needed to improve prognostication and guide decision making.

  15. Vascular Targeting in Pancreatic Cancer: The Novel Tubulin-Binding Agent ZD6126 Reveals Antitumor Activity in Primary and Metastatic Tumor Models

    Full Text Available ZD6126 is a novel vascular-targeting agent that acts by disrupting the tubulin cytoskeleton of an immature tumor endothelium, leading to an occlusion of tumor blood vessels and a subsequent tumor necrosis. We wanted to evaluate ZD6126 in primary and metastatic tumor models of human pancreatic cancer. Nude mice were injected orthotopically with L3.6pl pancreatic cancer cells. In single and multiple dosing experiments, mice received ZD6126, gemcitabine, a combination of both agents, or no treatment. For the induction of metastatic disease, additional groups of mice were injected with L3.6pl cells into the spleen. Twenty-four hours after a single-dose treatment, ZD6126 therapy led to an extensive central tumor necrosis, which was not seen after gemcitabine treatment. Multiple dosing of ZD6126 resulted in a significant growth inhibition of primary tumors and a marked reduction of spontaneous liver and lymph node metastases. Experimental metastatic disease could be significantly controlled by a combination of ZD6126 and gemcitabine, as shown by a reduction of the number and size of established liver metastases. As shown by additional in vitro and in vivo experiments, possible mechanisms involve antivascular activities and subsequent antiproliferative and proapoptotic effects of ZD6126 on tumor cells, whereas direct activities against tumor cells seem unlikely. These data highlight the antitumor and antimetastatic effects of ZD6126 in human pancreatic cancer and reveal benefits of adding ZD6126 to standard gemcitabine therapy.

    Salvage-line regorafenib monotherapy exhibited a marked survival benefit for metastatic colorectal cancer (mCRC). However, the toxicity of this regimen has resulted in the clinical use of a reduced dose of regorafenib. Thirty-two Japanese mCRC patients (median age=61 years) who had been treated with regorafenib were retrospectively examined. Best objective response rate was 0% and stable disease (SD) was 31%. Median progression-free survival was 81 days and median overall survival was 233 days. Adverse events of any grade were observed in all patients: 17 (53%) patients suffered grade 3 or 4 adverse events including fatigue (13%), anorexia (13%), hand-foot skin reaction (22%) and elevations of alanine aminotransferase/aspartate aminotransferase (19%/16%). One patient with grade 5 liver dysfunction was identified (3%). Twenty-nine (91%) patients required treatment dose reduction or a delay in treatment. The relative dose intensity was 59%. Regorafenib treatments were terminated because of disease progression (59%) or adverse events (34%). Despite a decrease in the intensity of regorafenib treatment, because of severe adverse events, a fairly favorable efficacy was achieved in Japanese patients.

    The purpose of this pilot study was to assess whether outcome in metastatic or recurrent breast cancer patients is related to metabolic response to endocrine therapy determined by 18 F-FDG PET/CT. The study group comprised 22 patients with breast cancer (age 58 ± 11 years, mean ± SD) who were scheduled to receive endocrine therapy. They were systematically assessed by PET/CT at baseline and after a mean of 10 ± 4 weeks for evaluation of response after induction. All patients demonstrated FDG-avid lesions on the baseline PET/CT scan. The metabolic response was assessed according to EORTC criteria and based on the mean difference in SUV max between the two PET/CT scans, and the patients were classified into four groups: complete or partial metabolic response, or stable or progressive metabolic disease (CMR, PMR, SMD and PMD, respectively). All patients were followed in our institution. Metastatic sites were localized in bone (n = 15), lymph nodes (n = 11), chest wall (n = 3), breast (n = 5), lung (n = 3), soft tissue (n = 1) and liver (n = 1). PMR was observed in 11 patients (50%), SMD in 5 (23%) and PMD in 6 (27%). The median progression-free survival (PFS) times were 20, 27 and 6 months in the PMR, SMD and PMD groups, respectively. PFS in the SMD group differed from that in the PMR and SMD groups (p < 0.0001). Metabolic response assessed by FDG PET/CT imaging in patients with metastatic breast cancer treated with endocrine therapy is predictive of the patients' PFS. (orig.)

    Introduction Patients with metastatic colorectal cancer can develop jaundice from intrahepatic or extrahepatic causes. Currently, there is little data on the underlying causes and overall survival after onset of jaundice. The purpose of this study was to characterize the causes of jaundice and determine outcomes. Methods Six hundred twenty-nine patients treated for metastatic colorectal cancer between 2004 and 2010 were retrospectively reviewed. Those developing jaundice were grouped as having intrahepatic or extrahepatic obstruction. Demographics, clinicopathologic, and outcome data were analyzed. Results Sixty-two patients with metastatic colorectal cancer developed jaundice. Intrahepatic biliary obstruction was most common, occurring in younger patients. Time from metastatic diagnosis to presentation of jaundice was similar between groups, as was the mean number of prior lines of chemotherapy. Biliary decompression was successful 41.7 % of the time and was attempted more commonly for extrahepatic causes. Median overall survival after onset of jaundice was 1.5 months and it was similar between groups, but improved to 9.6 months in patients who were able to receive further chemotherapy. Conclusions Jaundice due to metastatic colorectal cancer is an ominous finding, representing aggressive tumor biology or exhaustion of therapies. Biliary decompression is often difficult and should only be pursued when additional treatment options are available. PMID:25300799

    Metastatic growth in breast cancer (BC) has been proposed as an exclusive property of cancer stem cells (CSCs). However, formal proof of their identity as cells of origin of recurrences at distant sites and the molecular events that may contribute to tumor cell dissemination and metastasis development are yet to be elucidated. In this study, we analyzed a set of patient-derived breast cancer stem cell (BCSC) lines. We found that in vitro BCSCs exhibit a higher chemoresistance and migratory potential when compared with differentiated, nontumorigenic, breast cancer cells (dBCCs). By developing an in vivo metastatic model simulating the disease of patients with early BC, we observed that BCSCs is the only cell population endowed with metastatic potential. Gene-expression profile studies comparing metastagenic and non-metastagenic cells identified TAZ, a transducer of the Hippo pathway and biomechanical cues, as a central mediator of BCSCs metastatic ability involved in their chemoresistance and tumorigenic potential. Overexpression of TAZ in low-expressing dBCCs induced cell transformation and conferred tumorigenicity and migratory activity. Conversely, loss of TAZ in BCSCs severely impaired metastatic colonization and chemoresistance. In clinical data from 99 BC patients, high expression levels of TAZ were associated with shorter disease-free survival in multivariate analysis, thus indicating that TAZ may represent a novel independent negative prognostic factor. Overall, this study designates TAZ as a novel biomarker and a possible therapeutic target for BC.

    Breast cancer (BrCa) is the most frequent cancer type in women and a leading cause of cancer related deaths in the world. Despite the decrease in mortality due to better diagnostics and palliative care, there is a lack of prognostic markers of metastasis. Recently, the exploitation of liquid biopsies and in particular of the extracellular vesicles has shown promise in the identification of such prognostic markers. In this study we compared the proteomic content of exosomes derived from metastatic and non-metastatic human (MCF7 and MDA-MB-231) and mouse (67NR and 4T1) cell lines. We found significant differences not only in the amount of secreted exosomes but most importantly in the protein content of exosomes secreted from metastatic versus non-metastatic ones. We identified periostin as a protein that is enriched in exosomes secreted by metastatic cells and validated its presence in a pilot cohort of breast cancer patient samples with localized disease or lymph node (LN) metastasis.

    Two decades ago, Galectin-8 was described as a prostate carcinoma biomarker since it is only expressed in the neoplastic prostate, but not in the healthy tissue. To date, no biological function has been attributed to Galectin-8 that could explain this differential expression. In this study we silenced Galectin-8 in two human prostate cancer cell lines, PC3 and IGR-CaP1, and designed a pre-clinical experimental model that allows monitoring the pathology from its early steps to the long-term metastatic stages. We show for the first time that the natural and conserved expression of Gal-8 in tumour cells is responsible for the metastatic evolution of prostate cancer. In fact, Gal-8 controls the rearrangement of the cytoskeleton and E-Cadherin expression, with a major impact on anoikis and homotypic aggregation of tumour cells, both being essential processes for the survival of circulating tumour cells during metastasis. While localized prostate cancer can be cured, metastatic and advanced disease remains a significant therapeutic challenge, urging for the identification of prognostic markers of the metastatic process. Collectively, our results highlight Galectin-8 as a potential target for anti-metastatic therapy against prostate cancer. PMID:28591719

    The Multinational Phase 3, Randomized, Double-Blind, Placebo-Controlled Efficacy and Safety Study of Oral MDV3100 in Chemotherapy-Naive Patients With Progressive Metastatic Prostate Cancer Who Have Failed Androgen Deprivation Therapy (PREVAIL) trial was unique as it included patients with visceral disease. This analysis was designed to describe outcomes for the subgroup of men from PREVAIL with specific sites of visceral disease to help clinicians understand how these patients responded to enzalutamide prior to chemotherapy. Prespecified analyses examined the coprimary endpoints of radiographic progression-free survival (rPFS) and overall survival (OS) only. All other efficacy analyses were post hoc. The visceral subgroup was divided into liver or lung subsets. Patients with both liver and lung metastases were included in the liver subset. Of the 1717 patients in PREVAIL, 204 (12%) had visceral metastases at screening (liver only or liver/lung metastases, n = 74; lung only metastases, n = 130). In patients with liver metastases, enzalutamide was associated with an improvement in rPFS (hazard ratio [HR], 0.44; 95% confidence interval [CI], 0.22-0.90) but not OS (HR, 1.04; 95% CI, 0.57-1.87). In patients with lung metastases only, the HR for rPFS (0.14; 95% CI, 0.06-0.36) and the HR for OS (0.59; 95% CI, 0.33-1.06) favored enzalutamide over placebo. Patients with liver metastases had worse outcomes than those with lung metastases, regardless of treatment. Enzalutamide was well tolerated in patients with visceral disease. Enzalutamide is an active first-line treatment option for men with asymptomatic or mildly symptomatic chemotherapy-naive metastatic castration-resistant prostate cancer and visceral disease. Patients with lung-only disease fared better than patients with liver disease, regardless of treatment. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Cancer cells adapt their metabolism during tumorigenesis. We studied two isogenic breast cancer cells lines (highly metastatic 4T1; nonmetastatic 67NR to identify differences in their glucose and glutamine metabolism in response to metabolic and environmental stress. Dynamic magnetic resonance spectroscopy of 13C-isotopomers showed that 4T1 cells have higher glycolytic and tricarboxylic acid (TCA cycle flux than 67NR cells and readily switch between glycolysis and oxidative phosphorylation (OXPHOS in response to different extracellular environments. OXPHOS activity increased with metastatic potential in isogenic cell lines derived from the same primary breast cancer: 4T1 > 4T07 and 168FARN (local micrometastasis only > 67NR. We observed a restricted TCA cycle flux at the succinate dehydrogenase step in 67NR cells (but not in 4T1 cells, leading to succinate accumulation and hindering OXPHOS. In the four isogenic cell lines, environmental stresses modulated succinate dehydrogenase subunit A expression according to metastatic potential. Moreover, glucose-derived lactate production was more glutamine dependent in cell lines with higher metastatic potential. These studies show clear differences in TCA cycle metabolism between 4T1 and 67NR breast cancer cells. They indicate that metastases-forming 4T1 cells are more adept at adjusting their metabolism in response to environmental stress than isogenic, nonmetastatic 67NR cells. We suggest that the metabolic plasticity and adaptability are more important to the metastatic breast cancer phenotype than rapid cell proliferation alone, which could 1 provide a new biomarker for early detection of this phenotype, possibly at the time of diagnosis, and 2 lead to new treatment strategies of metastatic breast cancer by targeting mitochondrial metabolism.

    Among women with breast cancer, 30-40% will develop metastatic disease and only achieve an overall survival of less than 5 years. Despite new-targeted therapy, breast tumors that harbour similar histology or molecular phenotype differ in their response to treatment. To uncover potential new therapeutic targets and improve outcome, we performed data mining of cancer micro array databases. We found that high expression of the homologous recombination protein, RAD51, was significantly associated with high-grade breast cancer, aggressive subtypes and increased risk of metastasis. We confirmed using immunohistochemistry that RAD5 1 was highly expressed in metastatic tumours and high-grade triple negative, HER2+ and luminal-B tumours. This provided a rationale for targeting RAD5 1 in high-grade, therapy-resistant breast cancers. Here, we report for the first time preclinical evaluation of RAD5 1 as a therapeutic target. We found that, in-vitro high RAD5 expressing cell lines were resistant to PARP inhibitor while knockdown reversed this resistance. In-vivo, knockdown of RAD5 1 inhibited metastatic progression using a syngeneic breast cancer model and the seeding of human xenografts to distant sites, including brain and lung. Concurrent PARP inhibition reduced primary tumor growth and delayed metastasis supporting synthetic lethality in-vivo. Together these insights provide pre-clinical data demonstrating RAD5 1 as a new biomarker and potential therapeutic target against aggressive metastatic breast cancer. (author)

    Salvage palliative chemotherapy in metastatic colorectal cancer has been associated with significant improvement in survival. However, not all patients receive all available therapies. Travel burden can affect patient access and use of future therapy. The present study aims to determine relationship between travel distance (TD) and salvage palliative chemotherapy in patients with metastatic colorectal cancer. A patient cohort diagnosed with metastatic colorectal cancer during 2006-2010 in the province of Saskatchewan, Canada was studied. Logistic regression analyses were performed to assess relationship between travel distance and subsequent line therapies. The median age of 264 eligible patients was 62 years [interquartile range (IQR): 53-72]. The patients who received salvage systemic therapy had a median distance to travel of 60.0 km (IQR: 4.7-144) compared with 88.1 km (IQR: 4.8-189) if they did not receive second- or third-line therapy (P=0.06). In multivariate analysis distance to the cancer center therapies. Our result revealed that travel distance to the cancer center greater than 100 km was associated less frequent use of second or subsequent line therapies in patients with metastatic colorectal cancer.

    Full Text Available The present health technology assessment report evaluates the clinical and economic profile of cetuximab in first-line metastatic colorectal cancer (mCRC in Italy. The first part of the report addresses the epidemiological, clinical, social and economic impact of mCRC. In the second part, evidence of efficacy, safety and cost-effectiveness of cetuximab and its available alternatives is shown. Finally, a model-based economic evaluation aimed at comparing cetuximab-based re­gimens vs. alternative therapeutic strategies indicated in mCRC in Italy is presented. The model estimates the incremental cost-effectiveness of adding cetuximab to FOLFOX-4 or FOLFIRI based on KRAS status, vs. adding bevacizumab to FOLFOX-4 or vs. FOLFOX-4 or FOLFIRI alone. A theoretical analysis vs. panitumumab has also been performed, despite panitumumab is not yet reimbursed in Italy in first-line mCRC. Survival outcomes, quality of life and costs of patient ma­nagement are estimated through a Markov model, using the Italian National Healthcare Service (NHS perspective, over a 10 year period, taking into account KRAS status of patients. The results of the pharmaco-economic analysis show that cetuximab + FOLFOX-4 and cetuximab + FOLFIRI are associated with increased survival, increased cost and increased quality adjusted survival, compared to all other treatments currently indicated and reimbursed in Italy. Adding cetuximab to FOLFOX-4 or FOLFIRI, based on KRAS status shows favorable incremental cost-effectiveness ratio (ICER vs. adding bevacizumab to FOLFIRI or vs. FOLFOX-4 or FOLFIRI alone. ICER of cetuximab (in combination with FOLFOX-4 or FOLFIRI, compared to currently reimbursed alternatives, is estimated between 6 and 13 thousand Euros per QALY gai­ned, depending on alternative treatment. These estimates are robust in extensive sensitivity analyses. As a final result, both clinical and economic evidence analyzed in this health technology assessment leads to

  17. Olanzapine and Betamethasone Are Effective for the Treatment of Nausea and Vomiting due to Metastatic Brain Tumors of Rectal Cancer

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Brain lesions originating from metastasis of colorectal cancer represent 3-5% of all brain metastases and are relatively rare. Of all distant metastases of colorectal cancer, those to the liver are detected in 22-29% of cases, while those to the lungs are detected in 8-18% of cases. In contrast, brain metastasis is quite rare, with a reported incidence ranging from 0.4 to 1.8%. Treatments for metastatic brain tumors include surgery, radiotherapy, chemotherapy and supportive care with steroids, etc. Untreated patients exhibit a median survival of only approximately 1 month. The choice of treatment for brain metastasis depends on the number of lesions, the patient's general condition, nerve findings and presence of other metastatic lesions. We herein report the case of a 78-year-old male who presented with brain metastases originating from rectal carcinoma. He suffered from nausea, vomiting, anorexia and vertigo during body movement. He received antiemetics, glycerol and whole brain radiation therapy; however, these treatments proved ineffective. Olanzapine therapy was started at a dose of 1.25 mg every night. The persistent nausea disappeared the next day, and the frequency of vomiting subsequently decreased. The patient was able to consume solid food. Olanzapine is an antipsychotic that has recently been used as palliative therapy for refractory nausea and vomiting in patients receiving chemotherapy. We consider that olanzapine was helpful as a means of supportive care for the treatment of nausea and vomiting due to brain metastasis.

    Full Text Available The purpose of this case report is to show the potential benefit of Korean medicine therapy for treating multiple metastatic breast cancer. A 45-year-old Korean woman was diagnosed with right breast invasive ductal carcinoma in August 2012 but did not receive any treatment until October 2015 when she was diagnosed with stage 4 right breast cancer with multiple liver, bone, mesentery, retroperitoneum, and axillary lymph node metastases. After chemo-port insertion, she was treated with palliative chemotherapy and the first line of trastuzumab and paclitaxel, and the port was removed due to port infection. To treat sepsis, vancomycin and tazoperan were administered, before the third line of trastuzumab and paclitaxel was carried out. However, the patient gave up chemotherapy due to vancomycin-resistant enterococci and general weakness. Later, she received Korean medicine therapy with wild ginseng pharmacopuncture, distilled Soramdan S, Hae, and Jeobgoldan for 8 months, which led to a significant decrease of the multiple metastases. The patient was able to start walking again with the help of a walking stick. However, a new metastatic lesion was found on the right adrenal gland. This case suggests that the combination of chemotherapy and Korean medicine therapy may be valuable. Further research is indicated.

    Numerous studies have implicated the short arm of chromosome 8 as the site of one or more tumor suppressor genes inactivated in carcinogenesis of the prostate, colon, lung, and liver. Previously, we identified a homozygous deletion on chromosome 8p22 in a metastatic prostate cancer. To map this homozygous deletion physically, long-range restriction mapping was performed using yeast artificial chromosomes (YACs) spanning approximately 2 Mb of chromosome band 8p22. Subcloned genomic DNA and cDNA probes isolated by hybrid capture from these YACs were mapped in relation to one another, reinforcing map integrity. Mapped single-copy probes from the region were then applied to DNA isolated from a metastatic prostate cancer containing a chromosome 8p22 homozygous deletion and indicated that its deletion spans 730-970 kb. Candidate genes PRLTS (PDGF-receptor {beta}-like tumor suppressor) and CTSB (cathepsin B) are located outside the region of homozygous deletion. Genethon marker D8S549 is located approximately at the center of this region of homozygous deletion. Two new microsatellite polymorphisms, D8S1991 and D8S1992, also located within the region of homozygous deletion on chromosome 8p22, are described. Physical mapping places cosmid CI8-2644 telomeric to MSR (macrophage scavenger receptor), the reverse of a previously published map, altering the interpretation of published deletion studies. This work should prove helpful in the identification of candidate tumor suppressor genes in this region. 47 refs., 5 figs., 1 tab.

    Purpose: To evaluate ability of ferucarbotran-enhanced MR imaging (MRI) in differentiating metastases from nonsolid benign lesions of the liver according to signal-intensity characteristics. Materials and methods: Sixty-six consecutive patients, who had 138 focal hepatic lesions (26 cysts, 11 hemangiomas, and 101 metastases), underwent ferucarbotran-enhanced MRI. The signal-intensity pattern of each kind of lesion relative to the liver parenchyma on ferucarbotran-enhanced T2* and heavily T1-weighted gradient-echo images were assessed and categorized into the following three categories: high-intensity and iso-intensity, respectively (category A), high and low (category B), and iso- and low-intensity (category C). For category B, lesions were subdivided into two groups based on single-shot half-Fourier RARE images: category B1 (not significantly high-intensity) and category B2 (significantly high-intensity). Results: Category A had 11 hemangiomas and 2 metastatic tumors, category B1 had 97 metastatic tumors, category B2 had 2 metastatic tumors and 9 cysts, and category C had 17 cysts. When a tumor with a signal intensity of category A was considered to be hemangioma, category B1 metastasis, and category B2 and C cyst, the diagnostic accuracy for differentiating these lesions was 97% (134/138). Conclusion: The combination of signal-intensity pattern on ferucarbotran-enhanced T2*- and heavily T1-weighted gradient-echo MRI has ability to differentiate liver metastases from nonsolid benign lesions. However, T2-weighted single-shot half-Fourier RARE imaging should also be employed to achieve better performance.

    The aim of the present study was to investigate the feature genes in metastatic breast cancer samples. A total of 5 expression profiles of metastatic breast cancer samples were downloaded from the Gene Expression Omnibus database, which were then analyzed using the MetaQC and MetaDE packages in R language. The feature genes between metastasis and non‑metastasis samples were screened under the threshold of PSVM) classifier training and verification. The accuracy of the SVM classifier was then evaluated using another independent dataset from The Cancer Genome Atlas database. Finally, function and pathway enrichment analyses for genes in the SVM classifier were performed. A total of 541 feature genes were identified between metastatic and non‑metastatic samples. The top 10 genes with the highest betweenness centrality values in the PPI network of feature genes were Nuclear RNA Export Factor 1, cyclin‑dependent kinase 2 (CDK2), myelocytomatosis proto‑oncogene protein (MYC), Cullin 5, SHC Adaptor Protein 1, Clathrin heavy chain, Nucleolin, WD repeat domain 1, proteasome 26S subunit non‑ATPase 2 and telomeric repeat binding factor 2. The cyclin‑dependent kinase inhibitor 1A (CDKN1A), E2F transcription factor 1 (E2F1), and MYC interacted with CDK2. The SVM classifier constructed by the top 30 feature genes was able to distinguish metastatic samples from non‑metastatic samples [correct rate, specificity, positive predictive value and negative predictive value >0.89; sensitivity >0.84; area under the receiver operating characteristic curve (AUROC) >0.96]. The verification of the SVM classifier in an independent dataset (35 metastatic samples and 143 non‑metastatic samples) revealed an accuracy of 94.38% and AUROC of 0.958. Cell cycle associated functions and pathways were the most significant terms of the 30 feature genes. A SVM classifier was constructed to assess the possibility of breast cancer metastasis, which presented high accuracy in several

    Full Text Available Pazopanib is an oral angiogenesis inhibitor, currently approved for treatment of metastatic renal cell carcinoma (mRCC and soft tissue sarcoma. The present study analyzed the outcomes of pazopanib in first-line treatment of mRCC, in a single Italian cancer center. In the light of the retrospective, observational nature and the unselected population, our experience can be defined a real-world study. The medical records of 38 mRCC patients treated with front-line pazopanib were retrospectively reviewed and analyzed. The progression free survival (PFS and the overall survival (OS were the primary endpoints, while secondary objectives included Objective Response Rate (ORR, Disease Control Rate (DCR, and treatment tolerability. Pazopanib achieved a median PFS (mPFS of 12.7 months (95% CI, 6.9-18.5 months. The median OS (mOS was 26.2 months (95% CI, 12.6-39.9 months; the observed ORR and DCR were 30.3% and 72.7%, respectively, with a median duration of response of 11 weeks. mPFS appeared not to be influenced by number of co-morbidities (3, gender, Fuhrman grade and age. Conversely, the ORR and the DCR positively affect the mPFS (HR=0.05 [95% CI, 0.05-055], p=0.01; HR=0.10 [95% CI, 0.02-0.43], p=0.002 respectively. A worse outcome was associated with a lower mPFS in patients with liver metastases (p= 0.2 and with a high tumor burden (number of metastatic sites 6 (p= 0.08. Worst OS was observed in patients age >70 years old (HR=6.91 [95% CI, 1.49-31.91], p=0.01. The treatment was well tolerated: no grade 4 adverse events, nor discontinuation due to toxicities was reported. Grade 3 hypertension affected positively the OS reaching the statistical significance (HR=0.22 [95% CI, 0.05-0.8], p=0.03 and thyroid dysfunction (hypo and hyperthyroidism seems to correlate with better outcome in terms of a longer mPFS (HR=0.12 [95% CI, 0.02-0.78], p=0.02.

We have evaluated in vitro the effects of regorafenib in combination with silybin, a biologically active component extracted from the seeds of Silybum marianum, in a panel of human colon cancer cells. Furthermore, we have prospectively treated a cohort of 22 refractory mCRC patients with regorafenib plus silybin. Treatment with regorafenib determined a dose-dependent growth inhibition whereas treatment with silybin had no anti-proliferative effects among all cancer cells tested. The combined treatment with regorafenib and silybin induced synergistic anti-proliferative and apoptotic effects by blocking PI3K/AKT/mTOR intracellular pathway. Moreover, combined treatment with regorafenib and silybin increased the production of reactive oxygen species levels within cells. In an exploratory proof of concept clinical study in a cohort of 22 mCRC patients after failure of all standard therapies, the clinical activity of regorafenib in combination with silybin was assessed. A median progression-free survival of 10.0 months and a median overall survival of 17.6 months were observed in these patients. These results suggest that the combined treatment potentially increases the clinical efficacy of regorafenib. Moreover, due to its anti-oxidative properties, silybin could protect patients from drug-induced liver damages, allowing to continue an effective anti-cancer therapy. The present study suggests that silybin in combination with regorafenib is a promising strategy for treatment of metastatic colorectal patients.

    The aim of this study is to compare the perioperative and oncologic outcomes of open and laparoscopic approaches for concomitant resection of synchronous colorectal cancer and liver metastases. Between 2006 and 2015, all patients undergoing combined resection of primary colorectal cancer and liver metastases were included in the study (n=43). Laparoscopic and open groups were compared regarding clinical, perioperative and oncologic outcomes. There were 29 patients in the open group and 14 patients in the laparoscopic group. The groups were similar regarding demographics, comorbidities, histopathological characteristics of the primary tumor and liver metastases. Postoperative complication rate (44.8% vs . 7.1%, P=0.016) was higher, and hospital stay (10 vs . 6.4 days, P=0.001) longer in the open compared to the laparoscopic group. Overall survival (OS) was comparable between the groups (P=0.10); whereas, disease-free survival (DFS) was longer in laparoscopic group (P=0.02). According to the results, in patients, whose primary colorectal cancer and metastatic liver disease was amenable to a minimally invasive resection, a concomitant laparoscopic approach resulted in less morbidity without compromising oncologic outcomes. This suggests that a laparoscopic approach may be considered in appropriate patients by surgeons with experience in both advanced laparoscopic liver and colorectal techniques.

    Full Text Available Abstract Background The treatment of metastatic breast cancer (MBC remains a great clinical challenge as drug resistance frequently develops. Alternative agents that can overcome drug resistance would offer new therapeutic options. The primary aim of this phase II study was to evaluate the efficacy and safety of utidelone as a monotherapy or in combination with capecitabine in metastatic breast cancer patients previously treated with and resistant to anthracyclines and taxanes. Methods In two open-label, noncomparative clinical studies, patients with metastatic breast cancer who previously received anthracycline- and/or taxane-containing regimens were given (1 25 to 35 mg/m2/day intravenously infused utidelone, once daily for 5 days, in combination with 14 days of 2000 mg/m2 capecitabine, divided in two equal daily oral doses or (2 40 mg/m2/day intravenously infused utidelone, once daily for 5 days. These regimens were administered per each 21-day treatment cycle, and the maximum of treatment cycles allowed per protocol is 6. Objective response rate (ORR, progression-free survival (PFS, and tolerability were evaluated. Results In the combination study, 33 patients completed a median of 6 cycles of therapy, which was the highest cycles a trial patient could receive under the criteria of the study protocol. Efficacy was evaluated (n = 32 with an ORR of 42.4 % (FAS, 95 % CI, 26.6, 60.9 and a median PFS of 7.9 (FAS, 95 % CI, 6.1, 9.8 months. The monotherapy study (n = 63 resulted in an ORR of 28.57 % (FAS, 95 % CI, 18.4, 40.6 and a median PFS of 5.4 (FAS, 95 % CI, 2.9, 9.8 months. In both studies, common toxicities associated with utidelone administration included peripheral neuropathy, fatigue, myalgia, and arthralgia, but the toxicities were limited and manageable. Notably, very mild myelosuppression, low liver and renal toxicities, and very limited gastrointestinal toxic effect were observed, in contrast to other agents in

    Full Text Available CONTEXT AND OBJECTIVE: In metastatic breast cancer cases, the currently available therapeutic approaches provide minimal improvement in survival. As such, quality of life (QOL becomes one of the main objectives of treatment. It is not known whether current treatments derived from trials improve QOL. The aim was to evaluate changes in QOL among metastatic breast cancer patients receiving treatment derived from trials. DESIGN AND SETTING: Prospective observational QOL survey in a tertiary cancer center. METHODS: To evaluate the influence of current treatments on patients' QOL, the Medical Outcomes Study Short Form-36 (SF-36 and the Beck Depression Inventory (BDI were applied on three occasions: before starting treatment and at the 6th and 12th weeks, to consecutive metastatic breast cancer patients over a one-year period. RESULTS: We found an improvement in QOL in the sample evaluated (n = 40, expressed by changes in the overall SF-36 score (p = 0.002 and the BDI (p = 0.004. Taken individually, the SF-36 components Pain, Social Functioning and Mental Health also improved significantly. Patients with worse initial performance status and secondary symptoms displayed greater improvement than those with better initial performance status and asymptomatic disease (p < 0.001. Patients who received more than one type of therapy showed larger gains than those given only one type (p = 0.038. CONCLUSIONS: In our environment, current metastatic breast cancer treatments can improve QOL, especially among symptomatic patients and those with low performance status.

    Therapeutic targeting of late-stage breast cancer is limited by an inadequate understanding of how tumor cell signaling evolves during metastatic progression and by the currently available small molecule inhibitors capable of targeting these processes. Herein, we demonstrate that both β3 integrin and fibroblast growth factor receptor-1 (FGFR1) are part of an epithelial-mesenchymal transition (EMT) program that is required to facilitate metastatic outgrowth in response to fibroblast growth factor-2 (FGF2). Mechanistically, β3 integrin physically disrupts an interaction between FGFR1 and E-cadherin, leading to a dramatic redistribution of FGFR1 subcellular localization, enhanced FGF2 signaling and increased three-dimensional (3D) outgrowth of metastatic breast cancer cells. This ability of β3 integrin to drive FGFR signaling requires the enzymatic activity of focal adhesion kinase (FAK). Consistent with these mechanistic data, we demonstrate that FGFR, β3 integrin, and FAK constitute a molecular signature capable of predicting decreased survival of patients with the basal-like subtype of breast cancer. Importantly, covalent targeting of a conserved cysteine in the P-loop of FGFR1-4 with our newly developed small molecule, FIIN-4, more effectively blocks 3D metastatic outgrowth as compared with currently available FGFR inhibitors. In vivo application of FIIN-4 potently inhibited the growth of metastatic, patient-derived breast cancer xenografts and murine-derived metastases growing within the pulmonary microenvironment. Overall, the current studies demonstrate that FGFR1 works in concert with other EMT effector molecules to drive aberrant downstream signaling, and that these events can be effectively targeted using our novel therapeutics for the treatment of the most aggressive forms of breast cancer.

    Colorectal cancer (CRC) is a common malignancy. There is growing evidence that CRC incidence is increasing in the younger population. There is controversy surrounding the prognosis of young patients with CRC. In this study we reviewed Australian patients with metastatic CRC (mCRC) who were younger than 40 years of age at the time of diagnosis of metastatic disease. To our knowledge this is the first study to focus on this age group with mCRC. This was a retrospective study using data from the South Australian Metastatic Colorectal Cancer database. We compared patient and disease characteristics, management approaches, and outcomes for age groups Young-onset mCRC patients, when defined as aged younger than 40 years, have equivalent survival compared with their older counterparts. This is despite differences in disease characteristics and management approach between the 2 groups. Copyright © 2016 Elsevier Inc. All rights reserved.

    Arctigenin (ARC) has been shown to have an anti-cancer effect in various cell types and tissues. However, there have been no studies concerning metastatic colorectal cancer (CRC). In this study, we investigated the anti-metastatic properties of ARC on colorectal metastasis and present a potential candidate drug. ARC induced cell cycle arrest and apoptosis in CT26 cells through the intrinsic apoptotic pathway via MAPKs signaling. In several metastatic phenotypes, ARC controlled epithelial-mesenchymal transition (EMT) through increasing the expression of epithelial marker E-cadherin and decreasing the expressions of mesenchymal markers; N-cadherin, vimentin, β-catenin, and Snail. Moreover, ARC inhibited migration and invasion through reducing of matrix metalloproteinase-2 (MMP-2) and MMP-9 expressions. In an experimental metastasis model, ARC significantly inhibited lung metastasis of CT26 cells. Taken together, our study demonstrates the inhibitory effects of ARC on colorectal metastasis.

    To compare the perioperative outcomes associated with open and laparoscopic (LAP) surgical approaches for liver metastases. The American College of Surgeons National Surgical Quality Improvement Program database was used to identify all adult patients who underwent surgical therapy for metastatic liver tumors between 2006 and 2012 (N=7684). Patients who underwent >1 procedure were excluded. Logistic regression after matching on propensity scores was used to assess the association between surgical approaches and perioperative outcomes. A total of 4555 patients underwent open resection, 387 LAP resection, 297 open radiofrequency ablation (RFA), and 265 LAP RFA. In propensity-matched samples (over 95% of patients successfully matched), there was no significant difference between LAP resection and LAP RFA in perioperative complications and length of stay and both compared favorably with their open counterparts. Minimally invasive approaches for secondary hepatic malignancies were associated with improved postoperative morbidity and length of stay and should be preferred in appropriate patients.

  14. Na,K-ATPase isozymes in colorectal cancer and liver metastases

    2016-01-01

    Full Text Available The goal of this study was to define Na,K-ATPase α and β subunit isoform expression and isozyme composition in colorectal cancer cells and liver metastases. The α1, α3 and β1 isoforms were the most highly expressed in tumor cells and metastases; in the plasma membrane of non-neoplastic cells and mainly in a cytoplasmic location in tumor cells. α1β1 and α3β1 isozymes found in tumor and metastatic cells exhibit the highest and lowest Na+ affinity respectively and the highest K+ affinity. Mesenchymal cell isozymes possess an intermediate Na+ affinity and a low K+ affinity. In cancer, these ions are likely to favor optimal conditions for the function of nuclear enzymes involved in mitosis, especially a high intra-nuclear K+ concentration. A major and striking finding of this study was that in liver, metastasized CRC cells express the α3β1 isozyme. Thus, the α3β1 isozyme could potentially serve as a novel exploratory biomarker of CRC metastatic cells in liver.

    Full Text Available Abstract Background Metastatic brain cancers are the most common intracranial tumor and occur in about 15% of all cancer patients. In up to 10% of these patients, the primary tumor tissue remains unknown, even after a time consuming and costly workup. The Pathwork® Tissue of Origin Test (Pathwork Diagnostics, Redwood City, CA, USA is a gene expression test to aid in the diagnosis of metastatic, poorly differentiated and undifferentiated tumors. It measures the expression pattern of 1,550 genes in these tumors and compares it to the expression pattern of a panel of 15 known tumor types. The purpose of this study was to evaluate the performance of the Tissue of Origin Test in the diagnosis of primary sites for metastatic brain cancer patients. Methods Fifteen fresh-frozen metastatic brain tumor specimens of known origins met specimen requirements. These specimens were entered into the study and processed using the Tissue of Origin Test. Results were compared to the known primary site and the agreement between the two results was assessed. Results Fourteen of the fifteen specimens produced microarray data files that passed all quality metrics. One originated from a tissue type that was off-panel. Among the remaining 13 cases, the Tissue of Origin Test accurately predicted the available diagnosis in 12/13 (92.3% cases. Discussion This study demonstrates the accuracy of the Tissue of Origin Test when applied to predict the tissue of origin of metastatic brain tumors. This test could be a very useful tool for pathologists as they classify metastatic brain cancers.

    To prevent probable occult metastatic liver cancer from progressing to clinical disease, the author used internal radiation therapy as an effective adjuvant to surgical excision of primary Dukes' C colonic cancer. A calculated radiation dose of 5000 rads was delivered to the liver by injecting radioactive 32-P chromic phosphate colloid through the superior mesenteric and celiac arteries. When this was done, the colloid passed through the intestines and was mixed thoroughly with the blood and delivered to the liver by the portal vein. The Kupffer cells in the liver trapped the colloid, and a minimum amount passed through the liver and got into the general circulation. This kept the amount of colloid deposited in the bone marrow to a minimum. In a phase-I pilot study in which nine patients were treated, no serious side effects were noted. In eight patients, the liver has remained free of cancer for more than 1 year.

    According to the guidelines for metastatic breast cancer, hormone therapy for hormone receptor-positive metastatic breast cancer without life-threatening metastasis should be received prior to chemotherapy. Previous trials have investigated the sensitivity of chemotherapy for preoperative breast cancer based on the efficacy of neoadjuvant hormone therapy. In this retrospective study, we investigated the efficacy of chemotherapy for metastatic breast cancer in hormone therapy-effective and hormone therapy-ineffective cases. Patients who received chemotherapy after hormone therapy for metastatic breast cancer between 2006 and 2013 at our institution were investigated. A total of 32 patients received chemotherapy after hormone therapy for metastatic breast cancer. The median patient age was 59 years, and most of the primary tumors exhibited a T2 status. A total of 26 patients had an N(+) status, while 7 patients had human epidermal growth factor receptor 2-positive tumors. A total of 13 patients received clinical benefits from hormone therapy, with a rate of clinical benefit of subsequent chemotherapy of 30.8%, which was not significantly different from that observed in the hormone therapy-ineffective patients (52.6%). A total of 13 patients were able to continue the hormone therapy for more than 1 year, with a rate of clinical benefit of chemotherapy of 38.5%, which was not significantly different from that observed in the short-term hormone therapy patients (47.4%). The luminal A patients were able to continue hormone therapy for a significantly longer period than the non-luminal A patients (median survival time: 17.8 months vs 6.35 months, p = 0.0085). However, there were no significant differences in the response to or duration of chemotherapy. The efficacy of chemotherapy for metastatic breast cancer cannot be predicted based on the efficacy of prior hormone therapy or tumor subtype, and clinicians should administer chemotherapy in all cases of

    Recently, a high rate of brain metastases has been reported among patients with human epidermal growth factor receptor (HER2)-overexpressing metastatic breast cancer who were treated with trastuzumab. The present study examined risk factors for the development of brain metastasis in patients with HER2-overexpressing breast cancer who were treated with trastuzumab. We retrospectively reviewed 204 patients with HER-2-overexpressing breast cancer who were treated with a trastuzumab-containing regimen between 1999 and 2006. Patients with clinical symptoms were diagnosed as having brain metastases when brain magnetic resonance imaging (MRI) or a computed tomography (CT) scan revealed positive findings for brain metastases. The median follow-up time of this cohort was 53.6 months. Among the patients who received a trastuzumab-containing regimen, 74 patients (36.3%) developed brain metastases. The median survival from the diagnosis of brain metastases was 13.5 months (95% confidence interval [CI], 12.2-14.7 months). The median time interval between the beginning of trastuzumab treatment and the diagnosis of brain metastases was 13.6 months (range, 0.0-45.8 months). Among patients with brain metastases, the median overall survival period was 39 months. A multivariate logistic regression analysis showed that age (≤50 years), recurrent breast cancer, and liver metastases were significant risk factors for the development of brain metastases. Patients with HER2-overexpressing breast cancer treated with trastuzumab had a high incidence of brain metastases (36.3%). Routine screening for brain metastases 1 year after the start of trastuzumab treatment, may be warranted in younger patients (≤50 years) who had recurrent breast cancer with liver metastases.

    Colorectal cancer (CRC) is one of the main causes of cancer deaths in the world. This cancer can be divided into non-metastatic and metastatic CRC stages. CD3+CD56+ NKT cell subsets are a minor T cell subset in peripheral blood and conduct the killing of tumor cells in direct manner. Little is obvious about levels and surface markers of these cells such as NKG2D in different cancers, especially in CRC. We included 15 non-metastatic (low-grade), 11 non-metastatic (high-grade), 10 metastatic colorectal cancer patients and 18 healthy controls. The percentages of CD3+CD56+ NKT cells and NKG2D+CD56+ NKT cells from samples were analyzed by flow cytometry in peripheral blood mononuclear cells (PBMCs) of samples. We found that there was a significantly lower number of NKG2D+CD3+CD56+ cells in peripheral blood of patients with metastatic colorectal cancer compared with normal controls (77.53 ± 5.79 % vs 90.74 ± 9.84 %; pNKT cells was significantly lower in patients with metastatic colorectal cancer compared to healthy controls strengthens the hypothesis that NKT cells can play a substantial role in the protection against human colorectal cancer, and this opens up avenues for novel studies about elucidating the other aspects of tumor surveillance in CRC progression and immunotherapy (Tab. 2, Fig. 2, Ref. 46).

    Full Text Available Abstract Background This retrospective study evaluated the impact of disease progression and of specific sites of metastasis on patient reported outcomes (PROs that assess symptom burden and health related quality of life (HRQoL in women with metastatic breast cancer (mBC. Methods HER-2 negative mBC patients (n = 102 were enrolled from 7 U.S. community oncology practices. Demographic, disease and treatment characteristics were abstracted from electronic medical records and linked to archived Patient Care Monitor (PCM assessments. The PCM is a self-report measure of symptom burden and HRQoL administered as part of routine care in participating practices. Linear mixed models were used to examine change in PCM scores over time. Results Mean age was 57 years, with 72% of patients Caucasian, and 25% African American. Median time from mBC diagnosis to first disease progression was 8.8 months. Metastasis to bone (60%, lung (28% and liver (26% predominated at initial metastatic diagnosis. Results showed that PCM items assessing fatigue, physical pain and trouble sleeping were sensitive to either general effects of disease progression or to effects associated with specific sites of metastasis. Progression of disease was also associated with modest but significant worsening of General Physical Symptoms, Treatment Side Effects, Acute Distress and Impaired Performance index scores. In addition, there were marked detrimental effects of liver metastasis on Treatment Side Effects, and of brain metastasis on Acute Distress. Conclusions Disease progression has a detrimental impact on cancer-related symptoms. Delaying disease progression may have a positive impact on patients' HRQoL.

    Endometrial cancer is a prevalent cancer, and its metastasis causes low survival rate. This study aims to utilize DNA methylation data to investigate the mechanism of the development and metastasis of endometrial cancer. Methylation profiling data were down-loaded from Gene Expression Omnibus, including 8 hyperplasias, 33 primary and 53 metastatic endometrial cancers. COHCAP package and annotation files were utilized to identify differentially methylated genes (DMGs) and CpG islands between the three different endometrial diseases. STRING database and Cytoscape were used to analyze and visualize protein-protein interactions (PPIs) between DMGs. CytoNCA plugin was utilized to identify key nodes in PPI network. A total of 610, 1076, and 501 DMGs were identified between primary endometrial cancer and hyperplasia, metastatic endometrial cancer and hyperplasia, as well as metastatic and primary endometrial cancers, respectively. For the three DMG sets, 53 common hypermethylated DMGs (e.g. PAX6 and INSR) and 6 common hypomethylated DMGs (e.g. PRDM8, KLHL14, and DUSP6) were found. For primary-hyperplasia DMG set and metastasis-hyperplasia DMG set, 527 common DMGs were found. For these common DMGs, a PPI network involving 692 PPIs was constructed. For DMGs between metastatic and primary endometrial cancers, a PPI network involving 673 PPIs was established, with PAX6 and INSR in the top 20 DMGs in both networks. PRDM8, KLHL14, and DUSP6 had hypomethylated CpG islands. DMGs comparison, PPI network analysis, and analysis of differentially methylated CpG islands indicated that PAX6, INSR, PRDM8, KLHL14, and DUSP6 might participate in the development and metastasis of endometrial cancer.

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

    Massimo Cristofanilli

    2012-01-01

    Full Text Available Successful management of breast cancer in the metastatic setting is often confounded by resistance to chemotherapeutics, in particular anthracyclines and taxanes. The limited number of effective treatment options for patients with more aggressive biological subtypes, such as triple-negative metastatic breast cancer, is especially concerning. As such, a therapy clinically proven to be effective in this subtype would be of great value. Ixabepilone, a novel synthetic lactam analog of epothilone B, demonstrated better clinical outcomes in metastatic disease, particularly in triple-negative breast cancer. Most recently, studies have shown the activity of ixabepilone in the neoadjuvant setting, suggesting a role for this drug in primary disease. Notably, treating in the neoadjuvant setting might allow clinicians to explore the predictive value of biomarkers and response to treatment, as pharmacogenomic approaches to therapy continue to evolve. In this article, we review the efficacy and safety data of ixabepilone as a monotherapy and as a component of combination therapy for metastatic and primary breast cancer.

    Prostate cancer (PCa) outcomes are impacted by socioeconomic and biologic factors. Ethnicity plays a role in the former, but little is known about the responsiveness of metastatic PCa to androgen-deprivation therapy (ADT) among races. The Surveillance, Epidemiology, and End Results (SEER) registry was used to identify men who were diagnosed with distant, de novo, metastatic PCa from 2004 to 2012. Patterns of presentation, overall survival (OS), and PCa-specific mortality (PCSM) were determined for each race. E3805 clinical trial data also were retrospectively reviewed to assess outcomes of ADT and ADT plus docetaxel by race. Of all PCa diagnoses in SEER, distant, de novo, metastatic disease was diagnosed in 4.2% of non-Hispanic whites, 5.8% of Hispanic whites, 5.7% of blacks, 5.5% of Asians/Pacific Islanders, and 8.8% of American Indians/Alaska Natives (P blacks, respectively. Few Asians participated in the E3805 trial. Asian men have superior median OS and PCSM for distant, de novo, metastatic PCa than men of other race. Non-Hispanic whites and blacks who receive treatment with ADT or chemohormonal therapy have comparable outcomes.

    The metastatic potential of tumors can be evaluated by the quantitative detection of urokinase and DNA. The cell sample selected for examination is analyzed for the presence of high levels of urokinase and abnormal DNA using analytical flow cytometry and digital image analysis. Other factors such as membrane associated urokinase, increased DNA synthesis rates and certain receptors can be used in the method for detection of potentially invasive tumors.

A 66-year-old male was initially diagnosed with Union Internationale Contre le Cancer stage III descending colon cancer and underwent curative surgery. He received postoperative adjuvant chemotherapy; however, liver metastasis developed and a partial hepatectomy was performed thereafter. Unfortunately, pulmonary metastases and recurrent liver tumors were found despite a series of systemic treatments with multiple combinations of cytotoxic and biologic agents. Recently, a novel multikinase inhibitor, regorafenib, was approved for the treatment of metastatic colorectal cancer refractory to other therapeutic modalities. As further treatment, we combined regorafenib with FOLFIRI, which included dose escalations of irinotecan, after UGT1A1 genotyping analysis. The therapeutic results were promising, with the improvement in liver and pulmonary metastases being

    Many cancers demonstrate a non-random distribution of sites for distant relapse while others have the propensity to metastasize to multiple organ systems. One of the notable recent findings is that the breast cancer subtypes differ not only in their biological characteristics as primary tumors but also in their capacity for metastatic progression. This information could potentially be utilized in treatment decision making and surveillance strategies. Copyright © 2017 Elsevier Inc. All rights reserved.

    Administrative health care claims data are used for epidemiologic, health services, and outcomes cancer research and thus play a significant role in policy. Cancer stage, which is often a major driver of cost and clinical outcomes, is not typically included in claims data. Evaluate algorithms used in a dataset of cancer patients to identify patients with metastatic breast (BC), lung (LC), or colorectal (CRC) cancer using claims data. Clinical data on BC, LC, or CRC patients (between January 1, 2007 and March 31, 2010) were linked to a health care claims database. Inclusion required health plan enrollment ≥3 months before initial cancer diagnosis date. Algorithms were used in the claims database to identify patients' disease status, which was compared with physician-reported metastases. Generic and tumor-specific algorithms were evaluated using ICD-9 codes, varying diagnosis time frames, and including/excluding other tumors. Positive and negative predictive values, sensitivity, and specificity were assessed. The linked databases included 14,480 patients; of whom, 32%, 17%, and 14.2% had metastatic BC, LC, and CRC, respectively, at diagnosis and met inclusion criteria. Nontumor-specific algorithms had lower specificity than tumor-specific algorithms. Tumor-specific algorithms' sensitivity and specificity were 53% and 99% for BC, 55% and 85% for LC, and 59% and 98% for CRC, respectively. Algorithms to distinguish metastatic BC, LC, and CRC from locally advanced disease should use tumor-specific primary cancer codes with 2 claims for the specific primary cancer >30-42 days apart to reduce misclassification. These performed best overall in specificity, positive predictive values, and overall accuracy to identify metastatic cancer in a health care claims database.

    Full Text Available Abstract Background The prognosis of gastric cancer patients is difficult to predict because of defects in establishing the surgical-pathological features. Cancer-associated fibroblasts (CAFs have been found to play prominent role in promoting tumor growth, invasion and metastasis. Thus raises the hypothesis that the extent of CAFs prevalence may help to establish the prognosis of gastric cancer patients. Methods Immunochemistry and realtime-PCR experiments were carried out to compare the expression of proteins which are specific markers of CAFs or secreted by CAFs in the tumor and normal tissue specimens. The extent of CAFs' prevalence was graded according to immunochemical staining, and correlation was further analyzed between CAFs' prevalence and other tumor characteristics which may influence the prognosis of gastric cancer patients. Results Nearly 80 percent of normal gastric tissues were negative or weak positive for CAFs staining, while more than 60 percent of gastric cancer tissues were moderate or strong positive for CAFs staining. Realtime-PCR results also showed significant elevated expression of FAP, SDF-1 and TGF-β1 in gastric cancer tissues compared to normal gastric tissues. Further analysis showed that CAFs' prevalence was correlated with tumor size, depth of the tumor, lymph node metastasis, liver metastasis or peritoneum metastasis. Conclusions Reactive cancer associated fibroblasts (CAFs were frequently accumulated in gastric cancer tissues, and the prevalence of CAFs was correlated with tumor size, depth of the tumor and tumor metastasis, thus give some supports for establishing the prognosis of the gastric cancer patients.

  3. Management of locally advanced and metastatic colon cancer in elderly patients.

    2014-02-28

    Colon cancer is the second leading cause of cancer mortality in the United States with a median age at diagnosis of 69 years. Sixty percent are diagnosed over the age of 65 years and 36% are 75 years or older. At diagnosis, approximately 58% of patients will have locally advanced and metastatic disease, for which systemic chemotherapy has been shown to improve survival. Treatment of cancer in elderly patients is more challenging due to multiple factors, including disabling co-morbidities as well as a decline in organ function. Cancer treatment of elderly patients is often associated with more toxicities that may lead to frequent hospitalizations. In locally advanced disease, fewer older patients receive adjuvant chemotherapy despite survival benefit and similar toxicity when compared to their younger counterparts. A survival benefit is also observed in the palliative chemotherapy setting for elderly patients with metastatic disease. When treating elderly patients with colon cancer, one has to consider drug pharmacokinetics and pharmacodynamics. Since chronological age is a poor marker of a patient's functional status, several methods of functional assessment including performance status and activities of daily living (ADL) or instrumental ADL, or even a comprehensive geriatric assessment, may be used. There is no ideal chemotherapy regimen that fits all elderly patients and so a regimen needs to be tailored for each individual. Important considerations when treating elderly patients include convenience and tolerability. This review will discuss approaches to the management of elderly patients with locally advanced and metastatic colon cancer.

    Many authors have considered dental implants to be unrelated to increased risk of medication-related osteonecrosis of the jaw (MRONJ). Nevertheless, more recently, more cases of peri-implant MRONJ (PI-MRONJ) have been described, thus becoming a challenging health problem. Also, metastatic cancer deposits are not infrequently found at peri-implant sites and this may represent an additional complication for such treatments. We present the case of a breast cancer patient with PI-MRONJ, presenting a clinically and radiologically undetected metastasis within the necrotic bone, and highlight the necessity of an accurate histopathological analysis. A 66-year-old female patient, who had received intravenous bisphosphonates for bone breast cancer metastases, came to our attention for a non-implant surgery-triggered PI-MRONJ. After surgical resection of the necrotic bone, conventional and immunohistochemical examinations were performed, which showed breast cancer deposits within the necrotic bone. Cancer patients with metastatic disease, who are undergoing bisphosphonate treatment, may develop unusual complications, including MRONJ, which is a site at risk for hosting additional metastatic deposits that may be clinically and radiologically overlooked. Such risk is increased by previous or concomitant implant procedures. Consequently, clinicians should be prudent when performing implant surgery in cancer patients with advanced-stage disease and consider the possible occurrence of peri-implant metastases while planning adequate treatments in such patients.

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

    Throughout the world, breast cancer is among the major causes of cancer-related death and is the most common cancer found in women. The development of cancer molecular knowledge has surpassed the novel concept of cancer biology and unraveled principle targets for anticancer drug developments and treatment strategies. Metastatic breast cancer cells acquire their aggressive features through several mechanisms, including augmentation of survival, proliferation, tumorigenicity, and motility-related cellular pathways. Clearly, natural product-derived compounds have since long been recognized as an important source for anticancer drugs, several of which have been shown to have promising anti-metastasis activities by suppressing key molecular features supporting such cell aggressiveness. This review provides the essential details of breast cancer, the molecular-based insights into metastasis, as well as the effects and mechanisms of potential compounds for breast cancer therapeutic approaches. As the abilities of cancer cells to invade and metastasize are addressed as the hallmarks of cancer, compounds possessing anti-metastatic effects, together with their defined molecular drug action could benefit the development of new drugs as well as treatment strategies.

    2012-06-01

    Full Text Available Abstract Background Adoptive cell therapy (ACT with tumor-infiltrating lymphocytes (TIL in patients with metastatic melanoma has been reported to have a 56% overall response rate with 20% complete responders. To increase the availability of this promising therapy in patients with advanced melanoma, a minimally invasive approach to procure tumor for TIL generation is warranted. Methods A feasibility study was performed to determine the safety and efficacy of laparoscopic liver resection to generate TIL for ACT. Retrospective review of a prospectively maintained database identified 22 patients with advanced melanoma and visceral metastasis (AJCC Stage M1c who underwent laparoscopic liver resection between 1 October 2005 and 31 July 2011. The indication for resection in all patients was to receive postoperative ACT with TIL. Results Twenty patients (91% underwent resection utilizing a closed laparoscopic technique, one required hand-assistance and another required conversion to open resection. Median intraoperative blood loss was 100 mL with most cases performed without a Pringle maneuver. Median hospital stay was 3 days. Three (14% patients experienced a complication from resection with no mortality. TIL were generated from 18 of 22 (82% patients. Twelve of 15 (80% TIL tested were found to have in vitro tumor reactivity. Eleven patients (50% received the intended ACT. Two patients were rendered no evidence of disease after surgical resection, with one undergoing delayed ACT with generated TIL after relapse. Objective tumor response was seen in 5 of 11 patients (45% who received TIL, with one patient experiencing an ongoing complete response (32+ months. Conclusions Laparoscopic liver resection can be performed with minimal morbidity and serve as an effective means to procure tumor to generate therapeutic TIL for ACT to patients with metastatic melanoma.

    To investigate the treatment outcome and the toxicity of helical tomotherapy (HT) in patients with metastatic colorectal cancer (mCRC). We retrospectively reviewed 18 patients with 31 lesions from mCRC treated with HT between 2009 and 2013. The liver (9 lesions) and lymph nodes (9 lesions) were the most frequent sites. The planning target volume (PTV) ranged from 12 to 1,110 mL (median, 114 mL). The total doses ranged from 30 to 70 Gy in 10-30 fractions. When the alpha/beta value for the tumor was assumed to be 10 Gy for the biologically equivalent dose (BED), the total doses ranged from 39 to 119 Gy{sub 10} (median, 55 Gy{sub 10}). Nineteen lesions were treated with concurrent chemotherapy (CCRT). With a median follow-up time of 16 months, the median overall survival for 18 patients was 33 months. Eight lesions (26%) achieved complete response. The 1- and 3-year local progression free survival (LPFS) rates for 31 lesions were 45% and 34%, respectively. On univariate analysis, significant parameters influencing LPFS rates were chemotherapy response before HT, aim of HT, CCRT, PTV, BED, and adjuvant chemotherapy. On multivariate analysis, PTV < or =113 mL and BED >48 Gy{sub 10} were associated with a statistically significant improvement in LFPS. During HT, four patients experienced grade 3 hematologic toxicities, each of whom had also received CCRT. The current study demonstrates the efficacy and tolerability of HT for mCRC. To define optimal RT dose according to tumor size of mCRC, further study should be needed.

    Radionuclide liver scans were obtained in 89 preoperative patients with gastric cancer. Eight showed definite defects on liver scans. At laparotomy, 14 patients were found to have liver involvement secondary to gastric cancer. The sensitivity of liver scans to predict liver involvement is 57% (8/14), and the specificity is 100% (75/75). The patients with definite defects on liver scans had a lower rate of palliative resection of the primary tumors (2/8) than the patients with liver involvement and no scan abnormality (4/6). The patients with advanced lesions but without liver involvement had the highest probability of resecting the primary tumors (57/63 : 47 radical, and 10 palliative). Normal serum levels of liver chemistries did not preclude the presence of defects on liver scans. Additional three patients were found to have cirrhosis of the liver solely based on liver scans, which was confirmed at laparotomy. Radionuclide liver scans can predict liver involvement with very few false positives, and may discriminate patients unsuitable for laparotomy even with palliative intent.

    BACKGROUND: Circulating hypermethylated RASSF1A could be a novel and potential useful marker for monitoring patients with metastatic breast cancer. Technical obstacles include fragmentation of the circulating DNA, fluctuations in the concentration, low concentrations of circulating tumor DNA...... in circulating non-tumor DNA. As a proof of principle, there was concordance in the kinetics of the RASSF1A and the serological cancer biomarkers CA 15-3, CEA, and TPA. CONCLUSIONS: Methylation-sensitive restriction enzymes may be a useful methodological approach for monitoring circulating hypermethylated RASSF1...... of the rare circulating tumor DNA was initially optimized. By analysis of production of PCR amplicons from HpaII- or BstUI-treated DNA isolated from 24 patients with metastatic breast cancer, we located four regions resulting in sensitivities from 63 to 83 %. When examining samples from 24 control subjects...

Since this time, however, few case reports outlining real-world usage have been published in the literature. Here, we detail the clinical history of an elderly woman with KRAS wild-type colon cancer who received regorafenib after prior treatment with other agents. We show that by employing dose modification strategies to address adverse events, this patient was able to remain on therapy for 11 months and achieve stable disease.

    The aim of this study was to develop a novel cabazitaxel bone targeted nanoparticle (NP) system for improved drug delivery to the bone microenvironment. Nanoparticles were developed using poly(D,L-lactic-co-glycolic acid) and cabazitaxel as the core with amino-bisphosphonate surface conjugation. Optimization of nanoparticle physiochemical properties, in vitro evaluation in prostate cancer cell lines and in vivo testing in an intraosseous model of metastatic prostate cancer was performed. This bone targeted cabazitaxel nanocarrier system showed significant reduction in tumor burden, while at the same time maintaining bone structure integrity and reducing pain in the mouse tumor limb. This bone microenvironment targeted nanoparticle system and clinically relevant approach of evaluation represents a promising advancement for treating bone metastatic cancer.

  18. FIRST-LINE TREATMENT IN PATIENTS WITH INOPERABLE METASTATIC COLON CANCER

    Full Text Available First-line therapy for metastatic colon cancer is most important for a patient. Its median time to progression constitutes the bulk of the patient’s survival. Clearly, it is necessary to choose the most effective combinations of targeted drugs and chemotherapy regimens. The choice of therapy for patients with colon cancer is governed by both the clinical characteristics of the disease and the molecular changes of a tumor. In recent literature, there has been a great deal of evidence for the use of targeted drugs in different clinical situations; the results of comparative trials of different treatment combinations have been published. This all determines the reconsideration of the choice of a treatment regimen in patients with metastatic colon cancer; it is the topic of the present review.

    Metastatic breast cancer is a very serious life threatening condition that poses many challenges for the pharmaceutical development of effective chemotherapeutics. As the therapeutics targeted to the localized masses in breast improve, metastatic lesions in the brain slowly increase in their incidence compromising successful treatment outcomes overall. The blood-brain-barrier (BBB) is one important obstacle for the management of breast cancer brain metastases. New therapeutic approaches are in demand for overcoming the BBB's breaching by breast tumor cells. In this work we demonstrate the potential dual role of a natural antimicrobial plant defensin, PvD 1 : it interferes with the formation of solid tumors in the breast and concomitantly controls adhesion of breast cancer cells to human brain endothelial cells. We have used a combination of techniques that probe PvD 1 's effect at the single cell level and reveal that this peptide can effectively damage breast tumor cells, leaving healthy breast and brain cells unaffected. Results suggest that PvD1 quickly internalizes in cancer cells but remains located in the membrane of normal cells with no significant damage to its structure and biomechanical properties. These interactions in turn modulate cell adhesiveness between tumor and BBB cells. PvD 1 is a potential template for the design of innovative pharmacological approaches for metastatic breast cancer treatment: the manipulation of the biomechanical properties of tumor cells that ultimately prevent their attachment to the BBB.

    There is increasing interest in the use of non-toxic natural products for the treatment of various pathologies, including cancer. In particular, biologically active constituents of the ginger oleoresin ( Zingiber officinale Roscoe) have been shown to mediate anti-tumour activity and to contribute to the anti-inflammatory, antioxidant, antimicrobial, and antiemetic properties of ginger. Here we report on the inhibitory properties of [10]-gingerol against metastatic triple negative breast cancer (TNBC) in vitro and in vivo . We show that [10]-gingerol concentration-dependently induces apoptotic death in mouse and human TNBC cell lines in vitro . In addition, [10]-gingerol is well tolerated in vivo , induces a marked increase in caspase-3 activation and inhibits orthotopic tumour growth in a syngeneic mouse model of spontaneous breast cancer metastasis. Importantly, using both spontaneous and experimental metastasis assays, we show for the first time that [10]-gingerol significantly inhibits metastasis to multiple organs including lung, bone and brain. Remarkably, inhibition of brain metastasis was observed even when treatment was initiated after surgical removal of the primary tumour. Taken together, these results indicate that [10]-gingerol may be a safe and useful complementary therapy for the treatment of metastatic breast cancer and warrant further investigation of its efficacy, either alone or in combination with standard systemic therapies, in pre-clinical models of metastatic breast cancer and in patients.

    Gastric cancer (GC) currently prevails as the second cause of death by malignancy worldwide. Estimations suggest that 35 % of affected patients appear with synchronous distant metastases. The vast majority of patients present with hepatic metastatic disease, sometimes accompanied by synchronous peritoneal and lung dissemination. The disease mostly remains asymptomatic at an early stage, with few reported cases of incidental abdominal discomfort. As the cancer advances, symptoms such as nausea or vomiting arise, along with indigestion and dysphagia, blood loss in the form of melena or hematemesis, as well as anorexia and weight loss. Having spread to the liver, it also causes jaundice due to hepatomegaly and general inanition. Despite recent research on the therapeutic strategies against GC metastatic disease, surgical resection appears the only potentially curative approach. Unfortunately, the majority of patients are not eligible to undergo surgical intervention. With regard to treatment modalities of the advanced stage disease, the role of metastasectomy is still debatable and quite unclear, while prolonged survival was succeeded only under certain specific circumstances. Systemic chemotherapy remains however another option, as well as local management in the form of cryotherapy, radiofrequency ablation, or transcatheter arterial chemoembolization. The aims of this review were to evaluate the results of surgical treatment for metastatic GC with special reference to the extent of its histological spread and to present the recent literature in order to provide an update on the current concepts of advanced surgical management of this entity. Relevant publications in the last two decades are briefly reviewed.

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

    The substantial heterogeneity and hierarchical organization in liver cancer support the theory of liver cancer stem cells (LCSCs). However, the relationship between chronic hepatic inflammation and LCSC generation remains obscure. Here, we observed a close correlation between aggravated inflammation and liver progenitor cell (LPC) propagation in the cirrhotic liver of rats exposed to diethylnitrosamine. LPCs isolated from the rat cirrhotic liver initiated subcutaneous liver cancers in nonobese diabetic/severe combined immunodeficient mice, suggesting the malignant transformation of LPCs toward LCSCs. Interestingly, depletion of Kupffer cells in vivo attenuated the LCSC properties of transformed LPCs and suppressed cytokeratin 19/Oval cell 6-positive tumor occurrence. Conversely, LPCs cocultured with macrophages exhibited enhanced LCSC properties. We further demonstrated that macrophage-secreted tumor necrosis factor-α triggered chromosomal instability in LPCs through the deregulation of ubiquitin D and checkpoint kinase 2 and enhanced the self-renewal of LPCs through the tumor necrosis factor receptor 1/Src/signal transducer and activator of transcription 3 pathway, which synergistically contributed to the conversion of LPCs to LCSCs. Clinical investigation revealed that cytokeratin 19/Oval cell 6-positive liver cancer patients displayed a worse prognosis and exhibited superior response to sorafenib treatment. Our results not only clarify the cellular and molecular mechanisms underlying the inflammation-mediated LCSC generation but also provide a molecular classification for the individualized treatment of liver cancer.

    2015-01-01

    Objectives: This article reviews pharmacology, pharmacokinetic properties, clinical efficacy, and safety in metastatic breast cancer patients, as well as the predictive biomarkers for outcome of treatment with pemetrexed-based regimens. Methods: PubMed, Embase, OVID, and the Cochrane Library databases were searched from the beginning of each database without any limitations to the date of publication. Search terms were‘‘pemetrexed’’ or‘‘LY231514’’ or“Alimta”,“metastatic breast cancer”, and“advanced breast cancer”. Results: There were 15 studies (n ¼ 1002) meeting our criteria for evaluation. Eight single-agent trials (n ¼ 551) and seven using combinations with other agents (n ¼ 451) were identified that evaluated pemetrexed for use in patients with metastatic breast cancer. Response rates to pemetrexed as a single agent varied from 8%to 31%, and with combination therapy have been reported to be between 15.8% and 55.7%. With routine supplementation of patients with folic acid, dexamethasone, and vitamin B12, the toxicity profile of these patients was mild, including dose-limiting neutropenia and thrombocytopenia, as well as lower grades of reversible hepatotoxicity and gastrointestinal toxicity. Expression of thymidylate synthase (TS) and other biomarkers are associated with the prognosis and sensitivity for pemetrexed in breast cancer. Conclusion: Pemetrexed has shown remarkable activity with acceptable toxicities for treatment of metastatic breast cancer patients. Translational research on pemetrexed in breast cancer identified biomarkers as well as additional genes important to its clinical activity and toxicity. Further research is needed to clarify the role of pemetrexed in breast cancer treatment in order to guide oncologists. Copyright © 2015, Chinese Medical Association Production.

    Understanding the complex, multistep process of metastasis remains a major challenge in cancer research. Metastasis models can reveal insights in tumor development and progression and provide tools to test new intervention strategies. To develop a new cancer metastasis model, we used DU145 human prostate cancer cells and performed repeated rounds of orthotopic prostate injection and selection of subsequent lymph node metastases. Tumor growth, metastasis, cell migration and invasion were analyzed. Microarray analysis was used to identify cell migration- and cancer-related genes correlating with metastasis. Selected genes were silenced using siRNA, and their roles in cell migration and invasion were determined in transwell migration and Matrigel invasion assays. Our in vivo cycling strategy created cell lines with dramatically increased tumorigenesis and increased ability to colonize lymph nodes (DU145LN1-LN4). Prostate tumor xenografts displayed increased vascularization, enlarged podoplanin-positive lymphatic vessels and invasive margins. Microarray analysis revealed gene expression profiles that correlated with metastatic potential. Using gene network analysis we selected 3 significantly upregulated cell movement and cancer related genes for further analysis: EPCAM (epithelial cell adhesion molecule), ITGB4 (integrin β4) and PLAU (urokinase-type plasminogen activator (uPA)). These genes all showed increased protein expression in the more metastatic DU145-LN4 cells compared to the parental DU145. SiRNA knockdown of EpCAM, integrin-β4 or uPA all significantly reduced cell migration in DU145-LN4 cells. In contrast, only uPA siRNA inhibited cell invasion into Matrigel. This role of uPA in cell invasion was confirmed using the uPA inhibitors, amiloride and UK122. Our approach has identified genes required for the migration and invasion of metastatic tumor cells, and we propose that our new in vivo model system will be a powerful tool to interrogate the metastatic

    Current preclinical models of metastatic disease (particularly oligometastases) suggest that metastases appear in a hierarchical order. We attempted to identify systematic patterns of metastasis in non-small cell lung cancer (NSCLC) after radiation therapy (XRT). We analyzed 1074 patients treated from 12/21/1998 through 8/20/2012 with ≥60 Gy definitive radiation for initially non-metastatic NSCLC. Location and time of metastases were recorded. Regional nodal failure was noted, as was subsequent distal failure. For further analysis, we considered only the five most common sites of metastasis (bone, brain, liver, adrenal, and lung). Metastatic progression over time was defined and patterns elucidated with Chi square tests. Histologic findings were analyzed with Wilcoxon rank sum tests. A significant multistep linear progression was not apparent. Having a first metastasis in lung or bone was associated with respective 16% (median 2.4 months) and 15% likelihoods (median 7.9 months) of secondary brain metastasis. Initial metastasis in the brain led to metastasis in another organ 29.3% of the time, most often in the lung, bone, and liver (medians 3.6, 7.9, and 3.1 months). Adenocarcinoma was more likely than squamous to metastasize to the brain (18 vs. 9%) and any of the five major sites (41 vs. 27%). We did not appreciate dominant patterns suggesting a multi-step hierarchical order of metastasis. Rather, our findings suggest that certain subgroups may develop different patterns of spread depending on a variety of factors.

    .2 months (95% CI, 26.5-33.7 months) in 6 trials with data available, and progression-free survival was 12.4 months (95% CI, 10.0-14.3 months) in 9 trials with data available. In meta-regression analysis, variables significantly associated with conversion surgery were disease limited to the liver and a higher median number of cycles (close to 12). For patients with surgically unresectable metastatic colorectal cancer, FOLFOXIRI-Bev is associated with a significant overall response rate. Such an effective regimen leads to a probability of surgical conversion of distant metastases approaching 40%, with more than one-fourth of patients having an R0 resection.

    From the clinical point of view, rectal cancer and colon cancer are clearly different nosological units in their progress and treatment. The aim of this study was to analyse and clarify the differences between the behaviour of liver metastases from colon and rectal cancer. The study of these factors is important for determining an accurate prognosis and indication of the most effective surgical therapy and oncologic treatment of colon and rectal cancer as a systemic disease. 223 patients with metastatic disease of colorectal carcinoma operated at the Department of Surgery, University Hospital in Pilsen between January 1, 2006 and January 31, 2012 were included in our study. The group of patients comprised 145 men (65%) and 117 women (35%). 275 operations were performed. Resection was done in 177 patients and radiofrequency ablation (RFA) in the total of 98 cases. Our sample was divided into 3 categories according to the location of the primary tumor to C (colon), comprising 58 patients, S (c. sigmoideum) in 61 patients, and R (rectum), comprising 101 patients. Significance analysis of the studied factors (age, gender, staging [TNM classification], grading, presence of mucinous carcinoma, type of operation) was performed using ANOVA test. Overall survival (OS), disease-free interval (DFI) or no evidence of disease (NED) were estimated using Kaplan-Meier curves, which were compared with the log-rank and Wilcoxon tests. As regards the comparison of primary origin of colorectal metastases in liver regardless of their treatment (resection and RFA), our study indicated that rectal liver metastases showed a significantly earlier recurrence than colon liver metastases (shorter NED/DFI). Among other factors, a locally advanced finding, further R2 resection of liver metastases and positivity of lymph node metastases were statistically significant for the prognosis of an early recurrence of the primary colon and sigmoid tumor. Furthermore, we proved that in patients with

    Combination therapies with cetuximab (Erbitux ® ; Merck Serono UK Ltd) and panitumumab (Vectibix ® ; Amgen UK Ltd) are shown to be less effective in adults with metastatic colorectal cancer who have mutations in exons 2, 3 and 4 of KRAS and NRAS oncogenes from the rat sarcoma (RAS) family. The objective of the study was to estimate the cost effectiveness of these drugs in patients with previously untreated RAS wild-type (i.e. non-mutated) metastatic colorectal cancer, not eligible for liver resection at baseline, from the UK National Health Service and Personal Social Services perspective. We constructed a partitioned survival model to evaluate the long-term costs and benefits of cetuximab and panitumumab combined with either FOLFOX (folinic acid, fluorouracil and oxaliplatin) or FOLFIRI (folinic acid, fluorouracil and irinotecan) vs. FOLFOX or FOLFIRI alone. The economic analysis was based on three randomised controlled trials. Costs and quality-adjusted life-years were discounted at 3.5% per annum. Based on the evidence available, both drugs fulfil the National Institute for Health and Care Excellence's end-of-life criteria. In the analysis, assuming discount prices for the drugs from patient access schemes agreed by the drug manufacturers with the Department of Health, predicted mean incremental cost-effectiveness ratios for cetuximab + FOLFOX, panitumumab + FOLFOX and cetuximab + FOLFIRI compared with chemotherapy alone appeared cost-effective at the National Institute for Health and Care Excellence's threshold of £50,000 per quality-adjusted life-year gained, applicable to end-of-life treatments. Cetuximab and panitumumab were recommended by the National Institute for Health and Care Excellence for patients with previously untreated RAS wild-type metastatic colorectal cancer, not eligible for liver resection at baseline, for use within the National Health Service in England. Both treatments are available via the UK Cancer Drugs Fund.

    CT and US were carried out on 81 patients with hepatocellular carcinoma, 20 patients with cholangiocellular carcinoma and 94 patients with metastatic liver cancer. 1) Cystic degeneration was observed in one with hepatocellular carcinoma (1.2%), one with cholangiocellular carcinoma (5.0%) and 12 with metastatic liver cancer (12.8%) by US, but this change was observed in only 5 by CT (1,0,4, respectively). Metastatic liver cancer showed the highest incidence among these tumors. 2) The characteristics of cystic degeneration of the liver tumors were thickened wall and irregularity of the inner surface of the wall. 3) Judging from macroscopic and histopathological findings, liquefactive necrosis in the tumors was shown as ''echoluent'' area. We concluded that cystic degeneration was one of the important findings in metastatic liver cancer and that careful observation by US and CT avoided the confusion with other hepatic cystic diseases.

    The purpose of this study was to retrospectively investigate the contribution of (18)F-fluorodeoxyglucose-positron emission tomography/computed tomography ((18)F-FDG-PET/CT) to detection of metastatic bladder cancer. The present study included 79 patients (69 men and 10 women) undergoing (18)F-FDG-PET/CT upon suspicion of metastatic bladder cancer between July 2007 and April 2013. The mean age was 66.1 years with a standard deviation of 10.7 years (range, 21 to 85 years). Patients were required to fast for 6 hours prior to scanning, and whole-body PET scanning from the skull base to the upper thighs was performed approximately 1 hour after intravenous injection of 555 MBq of (18)F-FDG. Whole body CT scanning was performed in the cranio-caudal direction. FDG-PET images were reconstructed using CT data for attenuation correction. Suspicious recurrent or metastatic lesions were confirmed by histopathology or clinical follow-up. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of (18)F-FDG-PET/CT were 89%, 78%, 90%, 75%, and 86%, respectively. (18)F-FDG-PET/CT can detect metastases with high sensitivity and positive predictive values in patients with metastatic bladder carcinoma.

  16. Heterogeneity of estrogen receptor expression in circulating tumor cells from metastatic breast cancer patients.

    Full Text Available BACKGROUND: Endocrine treatment is the most preferable systemic treatment in metastatic breast cancer patients that have had an estrogen receptor (ER positive primary tumor or metastatic lesions, however, approximately 20% of these patients do not benefit from the therapy and demonstrate further metastatic progress. One reason for failure of endocrine therapy might be the heterogeneity of ER expression in tumor cells spreading from the primary tumor to distant sites which is reflected in detectable circulating tumor cells (CTCs. METHODS: A sensitive and specific staining protocol for ER, keratin 8/18/19, CD45 was established. Peripheral blood from 35 metastatic breast cancer patients with ER-positive primary tumors was tested for the presence of CTCs. Keratin 8/18/19 and DAPI positive but CD45 negative cells were classified as CTCs and evaluated for ER staining. Subsequently, eight individual CTCs from four index patients (2 CTCs per patient were isolated and underwent whole genome amplification and ESR1 gene mutation analysis. RESULTS: CTCs were detected in blood of 16 from 35 analyzed patients (46%, with a median of 3 CTCs/7.5 ml. In total, ER-negative CTCs were detected in 11/16 (69% of the CTC positive cases, including blood samples with only ER-negative CTCs (19% and samples with both ER-positive and ER-negative CTCs (50%. No correlation was found between the intensity and/or percentage of ER staining in the primary tumor with the number and ER status of CTCs of the same patient. ESR1 gene mutations were not found. CONCLUSION: CTCs frequently lack ER expression in metastatic breast cancer patients with ER-positive primary tumors and show a considerable intra-patient heterogeneity, which may reflect a mechanism to escape endocrine therapy. Provided single cell analysis did not support a role of ESR1 mutations in this process.

    Background Endocrine treatment is the most preferable systemic treatment in metastatic breast cancer patients that have had an estrogen receptor (ER) positive primary tumor or metastatic lesions, however, approximately 20% of these patients do not benefit from the therapy and demonstrate further metastatic progress. One reason for failure of endocrine therapy might be the heterogeneity of ER expression in tumor cells spreading from the primary tumor to distant sites which is reflected in detectable circulating tumor cells (CTCs). Methods A sensitive and specific staining protocol for ER, keratin 8/18/19, CD45 was established. Peripheral blood from 35 metastatic breast cancer patients with ER-positive primary tumors was tested for the presence of CTCs. Keratin 8/18/19 and DAPI positive but CD45 negative cells were classified as CTCs and evaluated for ER staining. Subsequently, eight individual CTCs from four index patients (2 CTCs per patient) were isolated and underwent whole genome amplification and ESR1 gene mutation analysis. Results CTCs were detected in blood of 16 from 35 analyzed patients (46%), with a median of 3 CTCs/7.5 ml. In total, ER-negative CTCs were detected in 11/16 (69%) of the CTC positive cases, including blood samples with only ER-negative CTCs (19%) and samples with both ER-positive and ER-negative CTCs (50%). No correlation was found between the intensity and/or percentage of ER staining in the primary tumor with the number and ER status of CTCs of the same patient. ESR1 gene mutations were not found. Conclusion CTCs frequently lack ER expression in metastatic breast cancer patients with ER-positive primary tumors and show a considerable intra-patient heterogeneity, which may reflect a mechanism to escape endocrine therapy. Provided single cell analysis did not support a role of ESR1 mutations in this process. PMID:24058649

    The urokinase-type plasminogen activator receptor (uPAR) is implicated in cancer invasion and metastatic development in prostate cancer and provides therefore an attractive molecular target for both imaging and therapy. In this study, we provide the first in vivo data on an antimetastatic effect...... of uPAR radionuclide targeted therapy in such lesions and show the potential of uPAR positron emission tomography (PET) imaging for identifying small foci of metastatic cells in a mouse model of disseminating human prostate cancer. Two radiolabeled ligands were generated in high purity and specific...... value of 100 nM in a competitive binding experiment. In vivo, uPAR targeted radionuclide therapy significantly reduced the number of metastatic lesions in the disseminated metastatic prostate cancer model, when compared to vehicle and nontargeted 177Lu groups (p

    Full Text Available Patients with newly diagnosed, early stage estrogen receptor positive (ER+ breast cancer often show disease free survival in excess of five years following surgery and systemic adjuvant therapy. An important question is whether diagnostic tumor tissue from the primary lesion offers an accurate molecular portrait of the cancer post recurrence and thus may be used for predictive diagnostic purposes for patients with relapsed, metastatic disease. As the class I phosphatidylinositol 3' kinase (PI3K pathway is frequently activated in ER+ breast cancer and has been linked to acquired resistance to hormonal therapy, we hypothesized pathway status could evolve over time and treatment. Biomarker analyses were conducted on matched, asynchronous primary and metastatic tumors from 77 patients with ER+ breast cancer. We examined whether PIK3CA and AKT1 alterations or PTEN and Ki67 levels showed differences between primary and metastatic samples. We also sought to look more broadly at gene expression markers reflective of proliferation, molecular subtype, and key receptors and signaling pathways using an mRNA analysis platform developed on the Fluidigm BioMark™ microfluidics system to measure the relative expression of 90 breast cancer related genes in formalin-fixed paraffin-embedded (FFPE tissue. Application of this panel of biomarker assays to matched tumor pairs showed a high concordance between primary and metastatic tissue, with generally few changes in mutation status, proliferative markers, or gene expression between matched samples. The collection of assays described here has been optimized for FFPE tissue and may have utility in exploratory analyses to identify patient subsets responsive to targeted therapies.

    As the incidence of invasive breast cancer will increase with age, the number of elderly patients with a diagnosis metastatic breast cancer will also rise. But the use of cytotoxic drugs in elderly metastatic breast cancer patients is not systematic and is dreaded by medical oncologists. The need for prospective oncologic data from this population seems increasingly obvious. The main objective of this review is to investigate design and characteristics of phase II trials that assess activity and feasibility of chemotherapies in elderly advanced/metastatic breast cancer patients. An electronic search in PUBMED allowed us to retrieve articles published in English language on phase II trials in elderly metastatic breast cancer between January 2002 and May 2016. Sixteen publications were finally included in this review. The primary endpoint was a simple, a composite, and a co-primary endpoints in 11, three, and two studies, respectively. Efficacy was the primary objective in 15 studies: simple (n = 10), composite (n = 3), co-primary endpoints (n = 2). Composite or co-primary endpoints combined efficacy and toxicity. Thirteen studies used multistage designs. Only five studies evaluated the feasibility, i.e., to jointly assess efficacy and tolerance to treatment (toxicity, quality of life, etc) as primary endpoint. Development of elderly specific phase III clinical trials might be challenging, it therefore seems essential to conduct phase II clinical trials evaluating jointly efficacy and toxicity in a well-defined geriatric population. Use of multistage designs that take into account heterogeneity would allow to identify a subpopulation at interim analysis and to reduce the number of patients exposed to an inefficient or a toxic treatment regimen. It is crucial to evaluate new therapies (targeted therapies, immunotherapies) using adequate methodologies (Study design, endpoint).

    Esophageal cancer (EC) is the fourth and sixth leading cause of cancer-related deaths in China and United States, respectively. The dismal prognosis of EC is mainly attributed to distant metastases, which may not be overcome by chemotherapy alone. Hence, the use of alternative adjuvant treatments, such as herbal medicines, for metastatic EC remains a great desire of patients. Our previous study demonstrated the in vivo anti-tumor and in vitro anti-invasion activities of Andrographis paniculata (AP) in esophageal cancer. In the present study, the chemical constituents of absorbed AP components through human intestinal Caco-2 cell monolayer were verified for the first time. The anti-migratory activities and suppressive effects on metastasis-related factors such as HER2, MMP2, MMP9, TM4SF3, CXCR4 of the absorbed AP components were revealed in esophageal cancer cells EC-109. The anti-tumor and anti-metastatic effects of AP water extract (1600 mg/kg) were further confirmed in metastatic esophageal xenograft-bearing mice. Besides, AP water extract acted synergistically with cisplatin plus 5-fluorouracil on inhibiting tumor nodule growth (with combination index present findings provide evidence on safety and advantages of the combined use of AP with chemotherapeutics in pre-clinical setting.

    Cancer cells efficiently transfer exosome contents (essentially mRNAs and microRNAs) to other cell types, modifying immune responses, cell growth, angiogenesis and metastasis. Here we analyzed the exosomes release by breast tumor cells with different capacities of stemness/metastasis based on CXCR4 expression, and evaluated their capacity to generate oncogenic features in recipient cells. Breast cancer cells overexpressing CXCR4 showed an increase in stemness-related markers, and in proliferation, migration and invasion capacities. Furthermore, recipient cells treated with exosomes from CXCR4-cells showed increased in the same abilities. Moreover, inoculation of CXCR4-cell-derived exosomes in immunocompromised mice stimulated primary tumor growth and metastatic potential. Comparison of nucleic acids contained into exosomes isolated from patients revealed a "stemness and metastatic" signature in exosomes of patients with worse prognosis. Finally, our data supported the view that cancer cells with stem-like properties show concomitant metastatic behavior, and their exosomes stimulate tumor progression and metastasis. Exosomes-derived nucleic acids from plasma of breast cancer patients are suitable markers in the prognosis of such patients.

    The chick-embryo model has been an important tool to study tumor growth, metastasis, and angiogenesis. However, an imageable model with a genetic fluorescent tag in the growing and spreading cancer cells that is stable over time has not been developed. We report here the development of such an imageable fluorescent chick-embryo metastatic cancer model with the use of green fluorescent protein (GFP). Lewis lung carcinoma cells, stably expressing GFP, were injected on the 12th day of incubation in the chick embryo. GFP-Lewis lung carcinoma metastases were visualized by fluorescence, after seven days additional incubation, in the brain, heart, and sternum of the developing chick embryo, with the most frequent site being the brain. The combination of streptokinase and gemcitabine was evaluated in this GFP metastatic model. Twelve-day-old chick embryos were injected intravenously with GFP-Lewis lung cancer cells, along with these two agents either alone or in combination. The streptokinase-gemcitabine combination inhibited metastases at all sites. The effective dose of gemcitabine was found to be 10 mg/kg and streptokinase 2000 IU per embryo. The data in this report suggest that this new stably fluorescent imageable metastatic-cancer chick-embryo model will enable rapid screening of new antimetastatic agents.

    Liver diseases are common worldwide and hepatocellular carcinoma (HCC) is the commonest primary liver cancer. It has varied incidences globally but it is particularly common in Africans with a high prevalence in Nigerians where it accounted for the 4th commonest cause of death in both sexes between 1976 and 1995 (table 1). Similarly its incidence has remained persistently high between 3.1 and 8.6% per annum. Hepatocellular carcinoma occurs among all socio-economic classes of the population and is commonest among the 30-50 year group, two decades earlier than in the Caucasians and Americans. However, patients with HCC present in several patterns with majority having sudden onset of abdominal pain and swelling which is usually progressive, running an aggressive course. These patients who are in their prime of life arrive late in hospitals when the disease is advanced and is unlikely to respond to the usual modalities of therapy hence the disease has a gloomy picture. The solution is EARLY DIAGNOSIS with PROMPT THERAPY for achieving possible CURE of the disease

    Primary liver cancer is the fifth most common cancer worldwide. Hepatocellular carcinoma accounts for 85-90% of primary liver cancers. Distribution of hepatocellular carcinoma shows variations among geographic regions and ethnic groups. Males have higher liver cancer rates than females. Hepatocellular carcinoma occurs within an established background of chronic liver disease and cirrhosis (70-90%). Major causes (80%) of hepatocellular carcinoma are hepatitis B, C virus infection, and aflatoxin exposition. Its development is a multistep process. We have a growing understanding on the molecular pathogenesis. Genetic and epigenetic changes activate oncogenes, inhibit tumorsuppressor genes, which result in autonomous cell proliferation. The chromosomal instability caused by telomere dysfunction, the growth-retrained environment and the alterations of the micro- and macroenvironment help the expansion of the malignant cells. Understanding the molecular mechanisms could improve the screening of patients with chronic liver disease, or cirrhosis, and the prevention as well as treatment of hepatocellular carcinoma.

    The goal of this study was to understand if exosomes derived from high-metastatic cells may influence the behavior of less aggressive cancer cells and the properties of the endothelium. We found that metastatic colon cancer cells are able to transfer their amoeboid phenotype to isogenic primary cancer cells through exosomes, and that this morphological transition is associated with the acquisition of a more aggressive behavior. Moreover, exosomes from the metastatic line (SW620Exos) exhibited higher ability to cause endothelial hyperpermeability than exosomes from the non metastatic line (SW480Exos). SWATH-based quantitative proteomic analysis highlighted that SW620Exos are significantly enriched in cytoskeletal-associated proteins including proteins activating the RhoA/ROCK pathway, known to induce amoeboid properties and destabilization of endothelial junctions. In particular, thrombin was identified as a key mediator of the effects induced by SW620Exos in target cells, in which we also found a significant increase of RhoA activity. Overall, our results demonstrate that in a heterogeneous context exosomes released by aggressive sub-clones can contribute to accelerate tumor progression by spreading malignant properties that affect both the tumor cell plasticity and the endothelial cell behavior.

    Full Text Available Colorectal cancer affects over one million people worldwide annually, with the liver being the most common site of metastatic spread. Adequate resection of hepatic metastases is the only chance for a cure in a subset of patients, and five-year survival increases to 35% with complete resection. Traditionally, computed tomographic imaging (CT was utilized for staging and to evaluate metastases in the liver. Recently, the introduction of hepatobiliary contrast-enhanced magnetic resonance imaging (MRI agents including gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Eovist in the United States, Primovist in Europe, or Gd-EOB-DTPA has proved to be a sensitive method for detection of hepatic metastases. Accurate detection of liver metastases is critical for staging of colorectal cancer as well as preoperative planning.

    Full Text Available After Taxotere fails, treatment options for metastatic prostate cancer are limited. The three drugs with FDA approval in this setting, Jevtana, Provenge and Zytiga, are associated with median survivals of less than 2 years. In part, the impact on survival is the result of low response rates, indicating a significant proportion of patients exhibiting de novo resistance to these agents. An alternate approach is to let treatment selection be governed by gene expression profiling so that the treatment is tailored to the specific patient. Here, we report a case of metastatic prostate cancer with a dramatic response to treatment selected based on molecular profiling. This patient had failed LHRH agonist, bicalutamide, Taxotere, and doxorubicin. Molecular profiling showed overexpression of the androgen receptor and he had a dramatic response of measurable disease to second-line hormonal therapy with ketoconazole, estrogen and Leukine.

    Abstract Fournier gangrene is a necrotizing soft tissue infection involving the perineum. We present a case of Fournier gangrene as the clinical presentation of perforated metastatic rectal cancer. The patient is a 78-year-old man in a nursing home who presented to our institution with necrosis and ischemia of the scrotum. After wide debridement of necrotic tissue and bilateral orchiectomy, computed tomography was carried out to investigate abnormal findings seen on his chest X-ray, which revealed multiple pulmonary metastases as well as a mass highly suspicious for a perforated rectal mass. Once stable, a diverting colostomy and biopsies of the rectal mass were performed, confirming the presence of a metastatic, poorly differentiated rectal adenocarcinoma. Albeit an unusual etiology of Fournier gangrene, this case highlights the rare but important causes of this deadly condition and teaches us to be cognizant of the variations in the presentation of colorectal cancer.

    Objective: To investigate the clinical effect of permanent 125 I seeds interstitial implants for metastatic cervical cancer. Methods: Under the guidance of the B-sonography, 125 I seeds were implanted into the eleven cervical lymph nodes of ten patients who had been given tumor resection. The pain relief and tumor size were observed in regular follow-up after one-month treatment. Results: All the patients were followed up for 6-14 months,and the postoperative recovery was good with no complication. One month after the implantation, the pain symptom was alleviated entirely in two nodes and partly in nine nodes. The tumor size shrank in ten nodes while there was no change in one node after one month. Conclusion: Permanent 125 I seeds interstitial implants for metastatic cervical cancer is a safe, minimally invasive and effective treatment. (authors)

    Importance Surgical resection has a potential benefit for patients with metastatic adenocarcinoma of the stomach and gastroesophageal junction. Objective To evaluate outcome in patients with limited metastatic disease who receive chemotherapy first and proceed to surgical resection. Design, Setting, and Participants The AIO-FLOT3 (Arbeitsgemeinschaft Internistische Onkologie–fluorouracil, leucovorin, oxaliplatin, and docetaxel) trial is a prospective, phase 2 trial of 252 patients with resectable or metastatic gastric or gastroesophageal junction adenocarcinoma. Patients were enrolled from 52 cancer care centers in Germany between February 1, 2009, and January 31, 2010, and stratified to 1 of 3 groups: resectable (arm A), limited metastatic (arm B), or extensive metastatic (arm C). Data cutoff was January 2012, and the analysis was performed in March 2013. Interventions Patients in arm A received 4 preoperative cycles of fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) followed by surgery and 4 postoperative cycles. Patients in arm B received at least 4 cycles of neoadjuvant FLOT and proceeded to surgical resection if restaging (using computed tomography and magnetic resonance imaging) showed a chance of margin-free (R0) resection of the primary tumor and at least a macroscopic complete resection of the metastatic lesions. Patients in arm C were offered FLOT chemotherapy and surgery only if required for palliation. Patients received a median (range) of 8 (1-15) cycles of FLOT. Main Outcomes and Measures The primary end point was overall survival. Results In total, 238 of 252 patients (94.4%) were eligible to participate. The median (range) age of participants was 66 (36-79) years in arm A (n = 51), 63 (28-79) years in arm B (n = 60), and 65 (23-83) years in arm C (n = 127). Patients in arm B (n = 60) had only retroperitoneal lymph node involvement (27 patients [45%]), liver involvement (11 [18.3%]), lung involvement (10 [16.7%]), localized

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

    Primary tumor resection (PTR) in metastatic breast cancer is not a standard treatment modality, and its impact on survival is conflicting. The primary objective of this study was to analyze impact of PTR on survival in metastatic patients with breast cancer. A retrospective study of metastatic patients with breast cancer was conducted using the 1988-2011 Surveillance, Epidemiology, and End Results (SEER) data base. Cox proportional hazards regression models were used to evaluate the relationship between PTR and survival and to adjust for the heterogeneity between the groups, and a propensity score-matched analysis was also performed. A total of 29 916 patients with metastatic breast cancer were included in the study, and 15 129 (51%) of patients underwent primary tumor resection, and 14 787 (49%) patients did not undergo surgery. Overall, decreasing trend in PTR for metastatic breast cancer in last decades was noted. Primary tumor resection was associated with a longer median OS (34 vs 18 months). In a propensity score-matched analysis, prognosis was also more favorable in the resected group (P = .0017). Primary tumor resection in metastatic breast cancer was associated with survival improvement, and the improvement persisted in propensity-matched analysis. © 2018 Wiley Periodicals, Inc.

    Full Text Available Androgen receptor (AR is frequently detected in breast cancers, and AR-targeted therapies are showing activity in AR-positive (AR+ breast cancer. However, the role of AR in breast cancers is still not fully elucidated and the biology of AR in breast cancer remains incompletely understood. Circulating tumor cells (CTCs can serve as prognostic and diagnostic tools, prompting us to measure AR protein expression and conduct genomic analyses on CTCs in patients with metastatic breast cancer.Blood samples from patients with metastatic breast cancer were deposited on glass slides, subjected to nuclear staining with DAPI, and reacted with fluorescent-labeled antibodies to detect CD45, cytokeratin (CK, and biomarkers of interest (AR, estrogen receptor [ER], and HER2 on all nucleated cells. The stained slides were scanned and enumerated by non-enrichment-based non-biased approach independent of cell surface epithelial cell adhesion molecule (EpCAM using the Epic Sciences CTC platform. Data were analyzed using established digital pathology algorithms.Of 68 patients, 51 (75% had at least 1 CTC, and 49 of these 51 (96% had hormone-receptor-positive (HR+/HER2-negative primary tumors. AR was expressed in CK+ CTCs in 10 patients. Of these 10 patients, 3 also had ER expression in CK+ CTCs. Single cell genomic analysis of 78 CTCs from 1 of these 3 patients identified three distinct copy number patterns. AR+ cells had a lower frequency of chromosomal changes than ER+ and HER2+ cells.CTC enumeration and analysis using no enrichment or selection provides a non-biased approach to detect AR expression and chromosomal aberrations in CTCs in patients with metastatic breast cancer. The heterogeneity of intrapatient AR expression in CTCs leads to the new hypothesis that patients with AR+ CTCs have heterogeneous disease with multiple drivers. Further studies are warranted to investigate the clinical applicability of AR+ CTCs and their heterogeneity.

    To evaluate the palliative role of radiotherapy (RT) and define the effectiveness of chemotherapy combined with palliative RT (CCRT) in patients with a symptomatic pelvic mass of metastatic colorectal cancer. From August 1995 to December 2007, 80 patients with a symptomatic pelvic mass of metastatic colorectal cancer were treated with palliative RT at Samsung Medical Center. Initial presenting symptoms were pain (68 cases), bleeding (18 cases), and obstruction (nine cases). The pelvic mass originated from rectal cancer in 58 patients (73%) and from colon cancer in 22 patients (27%). Initially 72 patients (90%) were treated with surgery, including 64 complete local excisions; 77% in colon cancer and 81% in rectal cancer. The total RT dose ranged 8-60 Gy (median: 36 Gy) with 1.8-8 Gy per fraction. When the α/β for the tumor was assumed to be 10 Gy for the biologically equivalent dose (BED), the median RT dose was 46.8 Gy 10 (14.4-78). Twenty one patients (26%) were treated with CCRT. Symptom palliation was assessed one month after the completion of RT. Symptom palliation was achieved in 80% of the cases. During the median follow-up period of five months (1-44 months), 45% of the cases experienced reappearance of symptoms; the median symptom control duration was five months. Median survival after RT was six months. On univariate analysis, the only significant prognostic factor for symptom control duration was BED ≥40 Gy 10 (p < 0.05), and CCRT was a marginally significant factor (p = 0.0644). On multivariate analysis, BED and CCRT were significant prognostic factors for symptom control duration (p < 0.05). RT was an effective palliation method in patients with a symptomatic pelvic mass of metastatic colorectal cancer. For improvement of symptom control rate and duration, a BED ≥ 40 Gy 10 is recommended when possible. Considering the low morbidity and improved symptom palliation, CCRT might be considered in patients with good performance status

    Full Text Available Andrew H KoDivision of Hematology/Oncology, Helen Diller Family Comprehensive Cancer Center, University of California, San Francisco, San Francisco, CA, USA Abstract: Nanoliposomal irinotecan (nal-IRI was originally developed using an efficient and high-loading capacity system to encapsulate irinotecan within a liposomal carrier, producing a therapeutic agent with improved biodistribution and pharmacokinetic characteristics compared to free drug. Specifically, administration of nal-IRI results in prolonged exposure of SN-38, the active metabolite of irinotecan, within tumors, while at the same time offering the advantage of less systemic toxicity than traditional irinotecan. These favorable properties of nal-IRI, confirmed in a variety of tumor xenograft models, led to its clinical evaluation in a number of disease indications for which camptothecins have proven activity, including in colorectal, gastric, and pancreatic cancers. The culmination of these clinical trials was the NAPOLI-1 (Nanoliposomal irinotecan with fluorouracil and folinic acid in metastatic pancreatic cancer after previous gemcitabine-based therapy trial, an international Phase III study evaluating nal-IRI both alone and in combination with 5-fluorouracil and leucovorin in patients with metastatic pancreatic adenocarcinoma following progression on gemcitabine-based chemotherapy. Positive results from NAPOLI-1 led to approval of nal-IRI (with 5-fluorouracil/leucovorin in October 2015 by the US Food and Drug Administration specifically for the treatment of metastatic pancreatic cancer in the second-line setting and beyond, a clinical context in which there had previously been no accepted standard of care. As such, nal-IRI represents an important landmark in cancer drug development, and potentially ushers in a new era where a greater number of patients with advanced pancreatic cancer can be sequenced through multiple lines of therapy translating into meaningful improvements in

  3. Novel near-diploid ovarian cancer cell line derived from a highly aneuploid metastatic ovarian tumor.

    Full Text Available A new ovarian near-diploid cell line, OVDM1, was derived from a highly aneuploid serous ovarian metastatic adenocarcinoma. A metastatic tumor was obtained from a 47-year-old Ashkenazi Jewish patient three years after the first surgery removed the primary tumor, both ovaries, and the remaining reproductive organs. OVDM1 was characterized by cell morphology, genotyping, tumorigenic assay, mycoplasma testing, spectral karyotyping (SKY, and molecular profiling of the whole genome by aCGH and gene expression microarray. Targeted sequencing of a panel of cancer-related genes was also performed. Hierarchical clustering of gene expression data clearly confirmed the ovarian origin of the cell line. OVDM1 has a near-diploid karyotype with a low-level aneuploidy, but samples of the original metastatic tumor were grossly aneuploid. A number of single nucleotide variations (SNVs/mutations were detected in OVDM1 and the metastatic tumor samples. Some of them were cancer-related according to COSMIC and HGMD databases (no founder mutations in BRCA1 and BRCA2 have been found. A large number of focal copy number alterations (FCNAs were detected, including homozygous deletions (HDs targeting WWOX and GATA4. Progression of OVDM1 from early to late passages was accompanied by preservation of the near-diploid status, acquisition of only few additional large chromosomal rearrangements and more than 100 new small FCNAs. Most of newly acquired FCNAs seem to be related to localized but massive DNA fragmentation (chromothripsis-like rearrangements. Newly developed near-diploid OVDM1 cell line offers an opportunity to evaluate tumorigenesis pathways/events in a minor clone of metastatic ovarian adenocarcinoma as well as mechanisms of chromothripsis.

    The use of circulating tumor cells (CTCs) and circulating extracellular vesicles (EVs), such as exosomes, as liquid biopsy-derived biomarkers for cancers have been investigated. CTC enumeration using the CellSearch based platform provides an accurate insight on overall survival where higher CTC counts indicate poor prognosis for patients with advanced metastatic cancer. EVs provide information based on their lipid, protein, and nucleic acid content and can be isolated from biofluids and analyzed from a relatively small volume, providing a routine and non-invasive modality to monitor disease progression. Our pilot experiment by assessing the level of two subpopulations of small EVs, the CD9 positive and CD63 positive EVs, showed that the CD9 positive EV level is higher in plasma from patients with advanced metastatic prostate cancer with detectable CTCs. These data show the potential utility of a particular EV subpopulation to serve as biomarkers for advanced metastatic prostate cancer. EVs can potentially be utilized as biomarkers to provide accurate genotypic and phenotypic information for advanced prostate cancer, where new strategies to design a more personalized therapy is currently the focus of considerable investigation. © 2017 Wiley Periodicals, Inc.

    To evaluate the prognostic significance of the lymphocyte to monocyte ratio (LMR) in patients with unresectable metastatic colorectal cancer who received palliative chemotherapy. A total of 104 patients with unresectable metastatic colorectal cancer who underwent palliative chemotherapy were enrolled. The LMR was calculated from blood samples by dividing the absolute lymphocyte count by the absolute monocyte count. Pre-treatment LMR values were measured within one week before the initiation of chemotherapy, while post-treatment LMR values were measured eight weeks after the initiation of chemotherapy. The median pre-treatment LMR was 4.16 (range: 0.58-14.06). We set 3.38 as the cut-off level based on the receiver operating characteristic curve. Based on the cut-off level of 3.38, 66 patients were classified into the high pre-treatment LMR group and 38 patients were classified into the low pre-treatment LMR group. The low pre-treatment LMR group had a significantly worse overall survival rate (P = 0.0011). Moreover, patients who demonstrated low pre-treatment LMR and normalization after treatment exhibited a better overall survival rate than the patients with low pre-treatment and post-treatment LMR values. The lymphocyte to monocyte ratio is a useful prognostic marker in patients with unresectable metastatic colorectal cancer who receive palliative chemotherapy.

    A radiolabeled monoclonal antibody (McAb) 6c6 was used to detect the metastatic lymph nodes of breast cancer externally and internally. 111 In was labeled to 6c6 by DTPA method. Iodogen method was used to label 131 I. The radiolabeled 6c6 was injected into the web space of each hand in seven women with breast cancer and one with benign breast tumor. The scans were positive in two axillae with palpable nodes and four with impalpable nodes. Pathologic examination later confirmed metastases in five of the axillae. Two axillae, one of them with palpable nodes, showed negative result, and here no tumor cells were found pathologically. Intraoperative metastatic lymph node detection with a hand-held gamma probe was carried out in six patients. 24 lymph nodes were measured with 17% (1/6) false negative and no false positive result (0/18), indicating that the result detected by the hand-held gamma probe presents the real radioactivity of the tissues being examined. There were 60 lymph nodes that were removed and detected again by well-shape detector after operation. The false positive rate was 14% (6/42), and the false negative rate was 11% (2/18), indicating that the radiolabeled McAb 6c6 could specifically combine with the metastatic lymph nodes of breast cancer in vivo

    Sequential endocrine treatments are recommended for estrogen receptor (ER) positive human epidermal growth factor receptor 2 (HER 2) negative metastatic breast cancers except in the case of symptomatic visceral disease. However, patients who suffer from disease progression while receiving a non-steroidal aromatase inhibitor (NSAI) have a very poor prognosis with standard endocrine therapy alone. Recently, based onthe results of the BOLERO 2 trial, the mammalian target of rapamycin (mTOR) inhibitor everolimus, combined with exemestane, a steroidal aromatase inhibitor, has been approved in Europe and the US for patients suffering from ER positive HER2 negative advanced breast cancer previously treated by a NSAI. The median progression-free survival (PFS) increased from 3.2 to 7.8 months in patients receiving everolimus and exemestane compared to placebo and exemestane. The magnitude of benefit was consistent in all pre-specified subgroups. Side effects were manageable and the quality of life was at least maintained. Everolimus has also beenrecently studied in HER2 positive locally advanced or metastatic disease in heavily pretreated patients (BOLERO 3 trial). This trial met its primary endpoint. The median PFS was increased in patients receiving trastuzumab, vinorelbine and everolimus compared to patients receiving trastuzumab, vinorelbine and placebo. We review pharmacological data and side effects of the drug. We also review the most important clinical trials leading to reimbursement of everolimus in metastatic breast cancer.

    Full Text Available Colorectal cancer (CRC is one of the leading causes of cancer mortality. Metastasis remains the primary cause of CRC death. Predicting the possibility of metastatic relapse in early-stage CRC is of paramount importance to target therapy for patients who really need it and spare those with low-potential of metastasis. Ninety-six stage II CRC cases were stratified using high-resolution array comparative genomic hybridization (aCGH data based on a predictive survival algorithm and supervised clustering. All genes included within the resultant copy number aberrations were each interrogated independently at mRNA level using CRC expression datasets available from public repositories, which included 1820 colon cancers, and 167 normal colon tissues. Reduced mRNA expression driven by copy number losses and increased expression driven by copy number gains revealed 42 altered transcripts (29 reduced and 13 increased transcripts associated with metastatic relapse, short disease-free or overall survival, and/or epithelial to mesenchymal transition (EMT. Resultant genes were classified based on gene ontology (GO, which identified four functional enrichment groups involved in growth regulation, genomic integrity, metabolism, and signal transduction pathways. The identified 42 genes may be useful for predicting metastatic relapse in stage II CRC. Further studies are necessary to validate these findings.

    To compare the expression of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER-2) in the primary site and the metastatic lesion of lymph nodes in invasive breast cancer for investigating whether the expression of these biomarkers in the primary site could act as a surrogate to the lymphatic metastatic lesion in the same patient. In lymphatic metastatic lesion and corresponding primary lesion of 107 cases of invasive breast cancer, ER and PR statuses were assessed by immunohistochemistry (IHC). HER-2 expression level was evaluated by IHC and/or fluorescence in situ hybridization (FISH). In the primary lesions, 43.9% were ER positive; 46.7% were PR positive; 34.6% were HER-2 positive. In corresponding lymphatic metastatic lesions, the HER-2 status was concordant in 90 patients; 9 patients were diagnosed positive in metastatic lesion while negative in primary lesion; 8 patients were negative in metastatic lesion while positive in primary site (agreement, 84.1%; κ=0.647). A change in ER status was observed in 24 cases: 17 cases positive in metastatic site while negative in primary site; 7 cases negative in metastatic site while positive in primary site (agreement, 77.6%; κ=0.534). PR status discordance between the primary lesion and the metastatic regional lymph nodes was reported in 19 cases (agreement, 82.2%; κ=0.640). This study revealed that there was only a moderate concordance of ER, PR and HER-2 status between primary tumors and metastatic lymph nodes. These results indicate that it was inappropriate to predict the status of ER, PR and HER-2 in metastatic lymph nodes based on the results of evaluation of that in primary lesions.

    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: 1) To define the incidence of isolated lung events in a cohort of women treated with conservative surgery (CS) and radiation therapy (RT) for early stage breast cancer. 2) Among such patients, to define the relative distribution of primary lung cancer, metastatic breast cancer, and indeterminate lesions; and to identify any predictors for a diagnosis of lung vs metastatic breast cancer. 3) To examine the cohort with respect to whether a higher than expected incidence of lung cancer is seen following breast irradiation. Materials and Methods: Between 1968 and 1986, 1865 patients with clinical stage I-II breast cancer were treated with CS and RT; the median follow-up for surviving patients is 129 months. The study population was limited to patients who developed a subsequent isolated lung event as the first site of distant disease. Isolated lung event was defined as disease limited to the thoracic cavity, without evidence of either uncontrolled local breast disease or metastatic disease elsewhere. Diagnosis of the lung event as a primary lung cancer, a metastatic breast lesion, or an indeterminate lesion was documented from the viewpoint of 1) the pathologic analysis and 2) the clinical impression at the time of the lung event. Results: Sixty six of the 1865 patients (3.5%) developed an isolated lung event. The relative distribution of the pathologic and clinical diagnoses is shown below: The 66 lung events were characterized either as a solitary pulmonary nodule (27), multiple nodules (23), pleural effusion alone (10), unknown (2), or miscellaneous other findings (4). Among the 47 patients for whom pathology was available, the diagnosis remained indeterminate for 24 (51%). For patients with a definitive pathologic diagnosis, 69% ((9(13))) of smokers had a new lung cancer compared to 20% ((2(10))) of non-smokers (p=0.036), and 67% ((10(15))) of patients with a solitary pulmonary nodule had lung cancer compared to 14% ((1(7))) for other lung presentations (p

    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.

    Breast cancer metastases cause significant patient mortality. During metastases, cancer cells use autophagy, a catabolic process to recycle nutrients via lysosomal degradation, to overcome nutritional stress for their survival. The Runt-related transcription factor, Runx2, promotes cell survival under metabolic stress, and regulates breast cancer progression and bone metastases. Here, we identify that Runx2 enhances autophagy in metastatic breast cancer cells. We defined Runx2 function in cellular autophagy by monitoring microtubule-associated protein light chain (LC3B-II) levels, an autophagy-specific marker. The electron and confocal microscopic analyses were utilized to identify alterations in autophagic vesicles. The Runx2 knockdown cells accumulate LC3B-II protein and autophagic vesicles due to reduced turnover. Interestingly, Runx2 promotes autophagy by enhancing trafficking of LC3B vesicles. Our mechanistic studies revealed that Runx2 promotes autophagy by increasing acetylation of α-tubulin sub-units of microtubules. Inhibiting autophagy decreased cell adhesion and survival of Runx2 knockdown cells. Furthermore, analysis of LC3B protein in clinical breast cancer specimens and tumor xenografts revealed significant association between high Runx2 and low LC3B protein levels. Our studies reveal a novel regulatory mechanism of autophagy via Runx2 and provide molecular insights into the role of autophagy in metastatic cancer cells. © 2017 Wiley Periodicals, Inc.

    Pazopanib is an oral angiogenesis inhibitor, currently approved for treatment of metastatic renal cell carcinoma (mRCC) and soft tissue sarcoma. The present study analyzed the outcomes of pazopanib in first-line treatment of mRCC, in a single Italian cancer center. In the light of the retrospective, observational nature and the unselected population, our experience can be defined a “real-world” study. The medical records of 38 mRCC patients treated with front-line pazopanib were retrospectively reviewed and analyzed. The progression free survival (PFS) and the overall survival (OS) were the primary endpoints, while secondary objectives included objective response rate (ORR), disease control rate (DCR), and treatment tolerability. Pazopanib achieved a median PFS (mPFS) of 12.7 months (95% CI, 6.9–18.5 months). The median OS (mOS) was 26.2 months (95% CI, 12.6–39.9 months); the observed ORR and DCR were 30.3 and 72.7%, respectively, with a median duration of response of 11 weeks. mPFS appeared not to be influenced by number of co-morbidities (< 3 vs. ≥3), gender, Fuhrman grade and age. Conversely, the ORR and the DCR positively affect the mPFS (HR = 0.05 [95% CI, 0.05–0.55], p = 0.01; HR = 0.10 [95% CI, 0.02–0.43], p = 0.002, respectively). A worse outcome was associated with a lower mPFS in patients with liver metastases (p = 0.2) and with a high tumor burden (number of metastatic sites < 6 vs. ≥6) (p = 0.08). Worst OS was observed in patients aged ≥70 years old (HR = 6.91 [95% CI, 1.49–31.91], p = 0.01). The treatment was well-tolerated: no grade 4 adverse events, nor discontinuation due to toxicities was reported. Grade 3 hypertension affected positively the OS reaching the statistical significance (HR = 0.22 [95% CI, 0.05–0.8], p = 0.03). Thyroid dysfunction (hypo and hyperthyroidism) seems to correlate with better outcome in terms of a longer mPFS (HR = 0.12 [95% CI, 0.02–0.78], p = 0.02). Our results are consistent with those reported in

    Carcinoembryonic antigen (CEA) is one of the most widely used tumor markers, and its level is increased in 30-60% of patients with pancreatic cancer (PC). However, little is known about the implications of CEA as a prognostic marker in metastatic PC. The purpose of this study was to examine the usefulness of CEA levels as a prognostic marker in patients with metastatic PC. We conducted a retrospective cohort study using data from a computerized database. A total of 433 patients with metastatic disease were analyzed. Median overall survival (OS) was significantly shorter for patients with high CEA (>5 ng/ml) than with normal CEA (≤5 ng/ml) (6.8 vs. 10.3 months, respectively; p CEA level was an independent predictive factor for OS (hazard ratio [HR], 1.81; 95% confidence interval [CI], 1.45-2.26). In the high CEA group, OS in patients treated with combination chemotherapy was similar to that with single-agent chemotherapy (median, 7.1 vs. 6.8 months; HR for OS, 0.99; 95% CI, 0.71-1.40). The present results show that CEA level is an independent prognostic factor in patients with metastatic PC. A combination chemotherapy regimen may offer modest survival benefit in patients with high CEA. Copyright © 2016 IAP and EPC. Published by Elsevier B.V. All rights reserved.

  3. Wnt Inactivation for Liver Cancer Therapy | Center for Cancer Research

    Science.gov (United States)

    Hepatocellular carcinoma (HCC) is the fifth most common and third most deadly type of cancer in the world. The majority of cases occur in Asia and Africa, resulting in most cases being diagnosed only at advanced stages of the disease when drug resistance is high. HCC typically follows damage to the liver such as cirrhosis, making radiation and chemotherapy a more challenging prospect. Surgery is also not a very viable option because less than one in four carcinomas can be completely removed. The limitations in these treatment modalities create the need for alternative therapeutic approaches.

    Trichilemmal carcinoma (TC) is described as a very rare cancer of the skin adnexa. 1 2 Ninety per cent of the lesions present on the scalp. Prognostic factors in TC are limited to lymph node status and surgical margins, with no statistical significance observed for age or gender of the patient, size of tumour or locoregional recurrence. We present a 46-year-old black patient who developed TC during treatment for breast cancer. Postoperative histology of the scalp lesion excision confirmed no involved margins. At the three monthly appointment, the patient was reviewed and multiple, new scalp lesions were noted. A CT scan of the head, neck found multiple lesions on the scalp, limited to the soft tissue, not involving the outer table of the skull. There was bilateral invasion of the parotid glands. To the best of our knowledge, no syndromes or associations between breast cancer and adnexal skin tumours exist. 2016 BMJ Publishing Group Ltd.

    The purpose of this study was to identify factors affecting local control of stereotactic body radiotherapy (SBRT) for lung tumors including primary lung cancer and metastatic lung tumors. Between June 2006 and June 2009, 159 lung tumors in 144 patients (primary lung cancer, 128; metastatic lung tumor, 31) were treated with SBRT with 48-60 Gy (mean 50.1 Gy) in 4-5 fractions. Higher doses were given to larger tumors and metastatic tumors in principle. Assessed factors were age, gender, tumor origin (primary vs. metastatic), histological subtype, tumor size, tumor appearance (solid vs. ground glass opacity), maximum standardized uptake value of positron emission tomography using 18 F-fluoro-2-deoxy-D-glucose, and SBRT doses. Follow-up time was 1-60 months (median 18 months). The 1-, 2-, and 3-year local failure-free rates of all lesions were 90, 80, and 77%, respectively. On univariate analysis, metastatic tumors (p<0.0001), solid tumors (p=0.0246), and higher SBRT doses (p=0.0334) were the statistically significant unfavorable factors for local control. On multivariate analysis, only tumor origin was statistically significant (p=0.0027). The 2-year local failure-free rates of primary lung cancer and metastatic lung tumors were 87 and 50%, respectively. A metastatic tumor was the only independently significant unfavorable factor for local control after SBRT. (author)

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

    Cancer patients who develop bone metastases are an estimated 60 to 84% . Of these 79% experienced pain syndromes are difficult to manage, of which 50% die without adequate pain relief and with a poor quality of life. Therefore, it is necessary to have accessible and effective medications for the management of this condition. The pathophysiology of pain in bone is reviewed and the drugs used most frequently in the management of this type of cancer pain are described. Furthermore an algorithm of 6 steps is presented and can guide the physician when making a therapeutic decision. (author) [es

    Full Text Available A 70-year-old woman with a history of lobular breast cancer presented to our Outpatient Clinic with diarrhoea for the past 3 years. Clinical examination and laboratory research were normal. Colonoscopy showed diffuse mild erythema and a decreased vascular pattern. Biopsies from the ascending colon, transverse colon, and descending colon showed metastases of lobular breast carcinoma. Although gastrointestinal metastases are rare in breast cancer, our case emphasizes the need for further diagnostic efforts in patients with gastrointestinal symptoms and a history of breast carcinoma.

    We analyzed the responses to first line treatment and clinical outcomes of metastatic breast cancer patients treated with palliative doxorubicin/cyclophosphamide (AC) according to molecular cancer subtype. A retrospective analysis was performed for 110 metastatic breast cancer patients selected on the basis of palliative AC treatment and the availability of immunohistochemical data for estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER-2/neu) status. Of the 110 patients analyzed, 71 (64.5%) were hormone receptor positive (HR+), 14 (12.7%) were HER2+, and 25 (22.7%) were triple negative (TN). There were no differences in age, stage at diagnosis, total number of cycles of palliative chemotherapy, incidence of visceral metastasis, and metastatic sites with the exception of liver among breast cancer subtypes. The overall response rates to AC were 55.9% for the HR+ subgroup, 42.9% for the HER2+ subgroup, and 56.5% for the TN subgroup. The progression-free survival (PFS) in patients with HER2+ and TN were significantly shorter than in the HR+ (median PFS, 9.1 vs 8.1 vs 11.5 months, respectively; p = 0.0002). The overall survival (OS) was 25.4 months in the TN subgroup and 27.3 months in HER2+ subgroup. The median OS for these two groups was significantly shorter than for patients in the HR+ subgroup (median, 38.5 months; 95% CI, 30.1-46.9 months; p < 0.0001). The response to palliative AC chemotherapy did not differ among breast cancer subtypes. Despite chemosensitivity for palliative AC, the TN subtype has a shorter overall survival than non-TN subtypes. Innovative treatment strategies should be developed to slow the course of disease

    2018-03-01

    Tumor lysis syndrome is a serious and sometimes lethal complication of cancer treatment that is comprised of a set of metabolic disturbances along with clinical manifestations. Initiating chemotherapy in bulky, rapidly proliferating tumors causes rapid cell turnover that in turn releases metabolites into circulation that give rise to metabolic derangements that can be dangerous. This syndrome is usually seen in high-grade hematological malignancies. Less commonly, tumor lysis syndrome can present in solid tumors and even rarely in genitourinary tumors. In this report, the authors describe a specific case of tumor lysis syndrome in a patient with metastatic prostate cancer following treatment with docetaxel.

  15. Gender Differences in Adipocyte Metabolism and Liver Cancer Progression

    Directory of Open Access Journals (Sweden)

    2016-09-01

    Full Text Available Liver cancer is the third most common cancer type and the second leading cause of deaths in men. Large population studies have demonstrated remarkable gender disparities in the incidence and the cumulative risk of liver cancer. A number of emerging risk factors regarding metabolic alterations associated with obesity, diabetes and dyslipidemia have been ascribed to the progression of non-alcoholic fatty liver diseases (NAFLD and ultimately liver cancer. The deregulation of fat metabolism derived from excessive insulin, glucose and lipid promotes cancer-causing inflammatory signaling and oxidative stress, which eventually triggers the uncontrolled hepatocellular proliferation. This review presents the current standing on the gender differences in body fat compositions and their mechanistic linkage with the development of NAFLD-related liver cancer, with an emphasis on genetic, epigenetic and microRNA control. The potential roles of sex hormones in instructing adipocyte metabolic programs may help unravel the mechanisms underlying gender dimorphism in liver cancer and identify the metabolic targets for disease management.

  16. Fluorodeoxyglucose--positive internal mammary lymph node in breast cancer patients with silicone implants: is it always metastatic cancer?

    2013-07-01

    Patients with breast cancer following mastectomy and silicone implant reconstruction may have enlarged internal mammary lymph nodes with pathological uptake on positron emission tomography with (18)F-fluorodeoxyglucose. This lymphadenopathy is usually considered as metastatic in nature, but has also been reported to be related to other conditions, including silicon migration. The purpose of this study was to determine the rate of metastatic disease in this unique group of patients. A retrospective comparative study of 12 female patients with breast cancer with silicone implants referred for biopsy due to isolated internal mammary lymph node fluorodeoxyglucose uptake on positron emission tomography. Five patients (41.6%) had histological findings related to silicone (n = 4) or non-specific inflammation (n = 1). The remaining 7 (58.3%) had histological evidence of cancer recurrence. There was no significant difference in the fluorodeoxyglucose-standardized uptake value between the two groups. Fluorodeoxyglucose-positive mammary lymph nodes in patients with breast cancer following silicone implant reconstruction may be due to metastatic deposits, non-specific inflammation or silicone migration. Clinical and imaging characteristics are insufficient in differentiating between these conditions. Biopsy is recommended prior to initiation of further treatment.

    We counted the lesions at the time of detection of bone metastases and calculated the rate of increase in the number of bone metastases from changes in serial bone scintigrams, and investigated the usefulness of serial scintigrams as a prognostic indicator in patients with metastatic bone tumors. Subjects were 112 patients with bone metastases from four types of primary lesion: 21 with prostate cancer, 27 breast cancer, 39 lung cancer and 25 stomach cancer. Of these, 18 (prostate), 19 (breast), nine (lung) and eight (stomach) underwent serial bone scintigrams in which bone metastases were first detected and identified as progressing. The numbers of lesions at the time of detection of bone metastases for prostate and stomach cancers were significantly greater than those for lung cancer. The rate of increase in the number of bone metastases for stomach cancer was significantly higher than that for prostate or breast cancers. There was no correlation between the survival time after the detection of bone metastases and the number of lesions at the time of detection in the four types of cancer. However, in prostate cancer, a negative correlation existed between the survival time after the detection of bone metastases and the rate of increase in the number of bone metastases. Thus, in patients with bone metastases from prostate cancer, it appears that the rate of increase in the number of bone metastases, estimated from serial bone scintigrams, was indicative of prognosis.

    Objective evaluation tools for assessing the effectiveness of stenting in palliative treatment of malignant biliary obstruction are not satisfactory. Effects of biliary stenting on liver volume change have never been studied. We aimed to use volumetry to analyze liver volume changes after endoscopic stenting in bile duct cancer according to the location and number of stents. Retrospective review. University hospital. Patients with a diagnosis of hilar or distal bile duct cancer and who underwent biliary metal stenting. ERCP with self-expandable metal stent placement. Liver volume change after biliary stenting and its comparison according to the location (hilar vs distal common bile duct) and number (hilar bilateral vs hilar unilateral). There were 60 patients; 31 were treated for hilar bile duct cancer (13 for bilateral stent and 18 for unilateral stent) and 29 for distal bile duct cancer. Overall mean follow-up duration was 11.7 ± 4.9 weeks. Liver volume increased 17.4 ± 24.1%. The rate of liver growth was rapid during the early period from 4 to 8 weeks. Stenting in hilar bile duct cancer tended to increase liver volume more than distal biliary stents (22.5% vs 11.9%, P = .091). In hilar bile duct cancer, unilateral and bilateral stents showed similar liver volume increases (20.1% and 25.8%, respectively; P = .512). Single center, retrospective. Biliary stenting markedly increased liver volume in both hilar and distal bile duct cancer. Our data suggest that liver volume assessment could be a useful tool for evaluating stent efficacy.

    The development of targeted therapies has undoubtedly broadened therapeutic options for patients with colorectal cancer (CRC). The use of bevacizumab to reduce angiogenesis has been associated with improved clinical outcomes. However, an urgent need for prognostic/predictive biomarkers for anti-angiogenic therapies still exists. Clinical data of 105 CRC patients treated with bevacizumab in conjunction with chemotherapy were analyzed. The expression of vascular endothelial growth factor (VEGF) receptors, NOTCH1 receptor and its ligand DLL4 were determined by immunohistochemistry. Tumor samples were arranged on a tissue microarray. The association between protein expression and clinicopathological characteristics and outcomes was determined. Bevacizumab was administered as a first-line of treatment in 70.5 % of our cases. The median progression-free survival (PFS) was 10.2 months. The median overall survival (OS) of the total cohort was 24.4 months. Bevacizumab, as the first-line of treatment, and the presence of liver metastasis were independently associated with objective response rate. Membrane VEGFR1 and VEGFR3 expressions were associated with the presence of lung metastasis; interestingly, VEGFR3 was associated with less liver metastasis. NOTCH1 expression was associated with lymph node metastasis. There was a trend toward association between improved PFS and lower NOTCH1 expression (p = 0.06). Improved OS was significantly associated with lower NOTCH1 expression (p = 0.01). In a multivariate analysis, ECOG (Eastern Cooperative Oncology Group) performance status, liver metastasis, histological grade, and NOTCH1 expression were independently associated with OS. Our findings illustrated the expression profile of angiogenesis-related proteins and their association with clinicopathological characteristics and outcomes. NOTCH1 expression is a detrimental prognostic factor in metastatic CRC patients treated with chemotherapy plus bevacizumab. The online version of

    To evaluate the risk of vertebral compression fracture (VCF) after conventional radiotherapy (RT) for colorectal cancer (CRC) with spine metastasis and to identify risk factors for VCF in metastatic and non-metastatic irradiated spines. We retrospectively reviewed 68 spinal segments in 16 patients who received conventional RT between 2009 and 2012. Fracture was defined as a newly developed VCF or progression of an existing fracture. The target volume included all metastatic spinal segments and one additional non-metastatic vertebra adjacent to the tumor-involved spines. The median follow-up was 7.8 months. Among all 68 spinal segments, there were six fracture events (8.8%) including three new VCFs and three fracture progressions. Observed VCF rates in vertebral segments with prior irradiation or pre-existing compression fracture were 30.0% and 75.0% respectively, compared with 5.2% and 4.7% for segments without prior irradiation or pre-existing compression fracture, respectively (both p < 0.05). The 1-year fracture-free probability was 87.8% (95% CI, 78.2-97.4). On multivariate analysis, prior irradiation (HR, 7.30; 95% CI, 1.31-40.86) and pre-existing compression fracture (HR, 18.45; 95% CI, 3.42-99.52) were independent risk factors for VCF. The incidence of VCF following conventional RT to the spine is not particularly high, regardless of metastatic tumor involvement. Spines that received irradiation and/or have pre-existing compression fracture before RT have an increased risk of VCF and require close observation.

    Quality of life is accepted as an important consideration in the management of patients with metastatic breast cancer, which remains incurable. Recent clinical trials of newer agents, such as eribulin and trastuzumab emtansine, have incorporated quality of life analyses. Quality of life is impacted by multiple patient-related, disease-related, and treatment-related factors. Therapies most beneficial for maintaining or improving quality of life include those that can effectively reduce tumor burden and tumor-related symptoms, but have toxicity profiles that are well tolerated and easily managed. Overall outcomes of patients with metastatic breast cancer improve when therapy is focused not only on the disease itself, but also on the goals of minimizing diseaserelated and treatment-related symptoms. A paradigm shift now reflected in major guidelines is the incorporation of palliative care strategies earlier in the course of metastatic disease management. The selection and sequence of treatments should be made in cooperation with the patient and after consideration of her particular priorities.

  5. Metastatic Carcinoma Occurring in a Gastric Hyperplastic Polyp Mimicking Primary Gastric Cancer: The First Reported Case

    2014-01-01

    Full Text Available Hyperplastic polyps of the stomach are regarded as benign. However, in rare cases they may contain incipient primary carcinomas. To our knowledge, breast carcinoma metastatic to a gastric hyperplastic polyp has not yet been reported. We describe the case of a 69-year-old woman to whom a gastric polyp was endoscopically excised. The patient had previously undergone a right mastectomy for mixed, invasive ductal and lobular carcinoma 5 years earlier. Histological sections from the gastric lesion showed typical features of hyperplastic polyp with foci of poorly differentiated adenocarcinoma including signet ring cells infiltrating the lamina propria. The histologic findings were consistent with a primary gastric cancer. However, the carcinoma cells were immunopositive for estrogen and progesterone receptors and GATA3 and negative for CDX2, Hep Par 1, and MUC5AC. E-cadherin showed membranous reactivity in some of the carcinoma cells while in others it was negative. Accordingly, metastatic mixed, lobular and ductal breast carcinoma was diagnosed. We conclude that metastatic adenocarcinoma mimicking primary gastric cancer can be rarely encountered in hyperplastic gastric polyps.

    Androgen deprivation is the mainstay of advanced prostate cancer treatment. Despite initial responses, almost all patients progress to castration-resistant prostate cancer (CRPC). The understanding of the biology of CRPC and the evidence that CRPC still remains driven by androgen receptor signaling led to the discovery of new therapeutic targets. In the last few years, large Phase III trials showed improvements in survival and outcomes and led to the approval of a CYP17 inhibitor (abiraterone), an androgen receptor antagonist (enzalutamide), the taxane cabazitaxel, an α-emitter (radium-223), the bone resorption-targeting drug denosumab and an immunotherapy (sipuleucel-T). This article describes the molecular mechanisms underlying castration resistance, discusses recent and ongoing trials and offers some insights into identifying the best sequence of new drugs.

    Full Text Available We describe a case of anaplastic meningioma presenting in an extracranial osseous location, initially diagnosed as cancer of unknown primary. Although anaplastic meningioma comprise 3% of all meningiomas, this subtype is more likely to be associated with metastases. The increased degree of dedifferentiation in anaplastic meningioma makes diagnosis difficult, especially if characteristic imaging findings of meningioma are not identified. Adequate tissue for diagnostic purposes and appropriate imaging studies may help in establishing a definitive diagnosis.

    Aim: This prospective study is to compare the results of primary (recurrence) and metastatic lesions detection, based on pathologic results, with computed tomography (CT) and/or magnetic resonance imaging (MRI) and positron emission tomography (PET) with [18F]-fluoro-2-deoxy-D-glucose (FDG) in invasive cervical cancer (ICC). Materials and Methods: An FDG PET scan was performed in 136 patients with ICC (107 squamous cell carcinoma [SCC], 18 adenocarcinoma [AdenoCa], 5 adeosquamous cell carcinoma, 4 small cell carcinoma, and 2 poorly differentiated carcinoma; from FIGO staging IB to IVB prior to operation). CT and/or MRI image were performed within one week before or after FDG PET scan was done. The accuracy of lymph node status was based on histological result or a second FDG PET combined with a CT and/or MRI image images. Results: Totally, 68 main tumor and 147 metastatic lesions were recognized by either histopathology or a follow up study. On a lesion basis, CT and/or MRI image images demonstrated 63 (92.6 %) main tumor and 103 (70.1 %) metastatic lesions. For lymph node metastatic lesions detection, there were 6(75 %) enlarged inguinal lymph nodes, 38(76 %) enlarged pelvic lymph nodes (PLN), 28(73.7 %) enlarged para-aortic lymph nodes (PAN), 8(50 %) enlarged supraclavicular lymph nodes (SLNs), and 5(62.5 %) enlarged mediastinal lymph nodes (MLNs). Liver metastases were found in 4(100 %), in lung in 7(70 %) and in bone in 5(83.3 %). Peritoneal metastases were found in 2(28.6 %). FDG PET demonstrated 63 (92.6 %) and 135 (91.8 %) metastatic lesions. For lymph node metastases, FDG PET found 8(100 %) enlarged inguinal lymph nodes, 44(88 %) enlarged PLNs, 36(94.7 %) enlarged PANs, 15(93.8 %) enlarged SLNs, and 8(100 %) enlarged MLNs. Liver metastases were found in 4(100 %), in lung in 9(90 %) and in bone in 6(100 %). Peritoneal metastases were found in 5(71.4 %). On a patient basis, with FDG PET scan, 31(22.8%) were upstaging while 4(2.9%) were down staging. 35

  10. Abiraterone Acetate: A Review in Metastatic Castration-Resistant Prostrate Cancer.

    Science.gov (United States)

    Scott, Lesley J

    2017-09-01

    Oral abiraterone acetate (Zytiga ® ) is a selective inhibitor of CYP17 and thereby inhibits androgen biosynthesis, with androgen signalling crucial in the progression from primary to metastatic prostate cancer (PC) and subsequently, in the development of metastatic castration-resistant PC (mCRPC). In large phase 3 trials and in the clinical practice setting, oral abiraterone acetate in combination with prednisone was an effective treatment and had an acceptable, manageable tolerability and safety profile in chemotherapy-naive and docetaxel-experienced men with mCRPC. In the pivotal global phase 3 trials, relative to placebo (+prednisone), abiraterone acetate (+prednisone) prolonged overall survival (OS) at data maturity (final analysis) and radiographic progression-free survival (rPFS) at all assessed timepoints. Given its efficacy in prolonging OS and its convenient once-daily oral regimen, in combination with prednisone, abiraterone acetate is an important first-line option for the treatment of mCRPC.

    The primary objective of this study was to identify the total intramural cost of illness of metastatic non-small cell lung cancer (NSCLC) in the Netherlands between 2006-2012. Secondary objective was to identify whether changes in cost patterns of metastatic NSCLC have occurred over the last years. Patients diagnosed with metastatic NSCLC between 1-1-2006 and 31-12-2012, who had follow-up to death or the date of data cut-off and no trial participation were included. A structured chart review was performed using a case report form. Data collection started after diagnosis of metastatic NSCLC and ended at death or April first, 2015. Data regarding outpatient visits, clinical attendance, oncolytic drug use, imaging, lab tests, radiotherapy and surgery were collected. Sixty-seven patients were included with a median age of 67 years. The median follow-up was 234days. On average patients had 28 outpatient visits and 11 inpatient days. Oncolytic drugs were administered to 76% of the patients. Mean per patient expenditures amounted up to €17,463, with oncolytic drugs (€6,390) as the main cost driver. In comparison with the time-period of 2003-2005 total per patient per year expenses decreased by 44%. The contribution to total yearly costs of oncolytic drugs increased from 18% to 35%, while costs for inpatient stay decreased from 52% to 28% of total expenditures. Outcomes in this study demonstrate that average treatment costs for metastatic NSCLC in the Netherlands Cancer Institute amount to €17,463. Compared to a prior study the average cost for metastatic NSCLC over time in the Netherlands has decreased. A shift of main cost drivers seems to have occurred from inpatient stay, to oncolytic drugs as main contributor. The shift towards treatment cost might become more visible with the introduction of immunotherapy. These results mark the importance of up-to-date cost of illness studies.

    Over 30% of ERα breast cancer patients develop relapses and progress to metastatic disease despite treatment with endocrine therapies. The pioneer factor PBX1 translates epigenetic cues and mediates estrogen induced ERα binding. Here we demonstrate that PBX1 plays a central role in regulating the ERα transcriptional response to epidermal growth factor (EGF) signaling. PBX1 regulates a subset of EGF-ERα genes highly expressed in aggressive breast tumours. Retrospective stratification of luminal patients using PBX1 protein levels in primary cancer further demonstrates that elevated PBX1 protein levels correlate with earlier metastatic progression. In agreement, PBX1 protein levels are significantly upregulated during metastatic progression in ERα-positive breast cancer patients. Finally we reveal that PBX1 upregulation in aggressive tumours is partly mediated by genomic amplification of the PBX1 locus. Correspondingly, ERα-positive breast cancer patients carrying PBX1 amplification are characterized by poor survival. Notably, we demonstrate that PBX1 amplification can be identified in tumor derived-circulating free DNA of ERα-positive metastatic patients. Metastatic patients with PBX1 amplification are also characterized by shorter relapse-free survival. Our data identifies PBX1 amplification as a functional hallmark of aggressive ERα-positive breast cancers. Mechanistically, PBX1 amplification impinges on several critical pathways associated with aggressive ERα-positive breast cancer. PMID:26215677

    BACKGROUND: Bowel cancer is the third most common cancer in the UK. Most bowel cancers are initially treated with surgery, but around 17% spread to the liver. When this happens, sometimes the liver tumour can be treated surgically, or chemotherapy may be used to shrink the tumour to make surgery

  15. Potentially functional SNPs (pfSNPs as novel genomic predictors of 5-FU response in metastatic colorectal cancer patients.

    Full Text Available 5-Fluorouracil (5-FU and its pro-drug Capecitabine have been widely used in treating colorectal cancer. However, not all patients will respond to the drug, hence there is a need to develop reliable early predictive biomarkers for 5-FU response. Here, we report a novel potentially functional Single Nucleotide Polymorphism (pfSNP approach to identify SNPs that may serve as predictive biomarkers of response to 5-FU in Chinese metastatic colorectal cancer (CRC patients. 1547 pfSNPs and one variable number tandem repeat (VNTR in 139 genes in 5-FU drug (both PK and PD pathway and colorectal cancer disease pathways were examined in 2 groups of CRC patients. Shrinkage of liver metastasis measured by RECIST criteria was used as the clinical end point. Four non-responder-specific pfSNPs were found to account for 37.5% of all non-responders (P<0.0003. Five additional pfSNPs were identified from a multivariate model (AUC under ROC = 0.875 that was applied for all other pfSNPs, excluding the non-responder-specific pfSNPs. These pfSNPs, which can differentiate the other non-responders from responders, mainly reside in tumor suppressor genes or genes implicated in colorectal cancer risk. Hence, a total of 9 novel SNPs with potential functional significance may be able to distinguish non-responders from responders to 5-FU. These pfSNPs may be useful biomarkers for predicting response to 5-FU.

    Breast cancer is one of the most common causes of cancer death in women worldwide. The Glasgow Prognostic Score (GPS), a cumulative prognostic score based on C-reactive protein and albumin, indicates the presence of a systemic inflammatory response. The GPS has been adopted as a powerful prognostic tool for patients with various types of malignant tumors, including breast cancer. The aim of this study was to assess the value of the GPS in predicting the response and toxicity in breast cancer patients treated with chemotherapy. Patients with metastatic breast cancers in a progressive stage for consideration of chemotherapy were eligible. The clinical characteristics and demographics were recorded. The GPS was calculated before the onset of chemotherapy. Data on the response to chemotherapy and progression-free survival (PFS) were also collected. Objective tumor responses were evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST). Toxicities were graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTC) version 3.0 throughout therapy. In total, 106 breast cancer patients were recruited. The GPS was associated with the response rate (p = 0.05), the clinical benefit rate (p = 0.03), and PFS (p = 0.005). The GPS was the only independent predictor of PFS (p = 0.005). The GPS was significantly associated with neutropenia, thrombocytopenia, anorexia, nausea and vomiting, fatigue, and mucositis (p = 0.05-0.001). Our data demonstrate that GPS assessment is associated with poor clinical outcomes and severe chemotherapy-related toxicities in patients with metastatic breast cancer who have undergone chemotherapy, without any specific indication regarding the type of chemotherapy applied. © 2016 S.

    To evaluate the prognostic value of metabolic activity of metastatic lesions measured by 18 F-flurodeoxyglucose ( 18 F-FDG) uptake on preoperative positron emission tomography/computed tomography (PET/CT) in patients with advanced serous epithelial ovarian cancer (EOC). Clinico-pathological variables and PET/CT parameters such as the maximum standardised uptake value of the ovarian cancer (SUV ovary ), metastatic lesions (SUV meta ), and the metastatic lesion-to-ovarian cancer standardised uptake value ratio (SUV meta /SUV ovary ) were assessed in International Federation of Gynaecology and Obstetrics (FIGO) stage III, IV patients. Clinico-pathological data were retrospectively reviewed for 94 eligible patients. The median progression-free survival (PFS) was 18.5 months (range, 6-90 months), and 57 (60.6%) patients experienced recurrence. Older age [P = 0.017, hazard ratio (HR) 1.036, 95% CI 1.006-1.066], residual disease after surgery (P = 0.024, HR 1.907, 95% CI 1.087-3.346), and high SUV meta /SUV ovary (P = 0.019, HR 2.321, 95% CI 1.148-4.692) were independent risk factors of recurrence. Patients with high SUV meta /SUV ovary showed a significantly worse PFS than those with low SUV meta /SUV ovary (P = 0.007, log-rank test). Preoperative SUV meta /SUV ovary was significantly associated with recurrence and has an incremental prognostic value for PFS in patients with advanced serous EOC. (orig.)

    Full Text Available We evaluate the outcomes of irradiation by using three-dimensional radiation therapy (3D-RT or intensity-modulated radiotherapy (IMRT for recurrent and metastatic cervical cancer. Between 2007 and 2010, 50 patients with recurrent and metastatic cervical cancer were treated using 3D-RT or IMRT. The median time interval between the initial treatment and the start of irradiation was 12 (6-51 months. Salvage surgery was performed before irradiation in 5 patients, and 38 patients received concurrent chemotherapy. Sixteen patients underwent 3D-RT, and 34 patients received IMRT. Median follow-up for all the patients was 18.3 months. Three-year overall survival and locoregional control were 56.1% and 59.7%, respectively. Three-year progression-free survival and disease-free survival were 65.3% and 64.3%, respectively. Nine patients developed grade 3 leukopenia. Grade 5 acute toxicity was not observed in any of the patients; however, 2 patients developed Grade 3 late toxicity. 3D-RT or IMRT is effective for the treatment of recurrent and metastatic cervical cancer, with the 3-year overall survival of 56.1%, and its complications are acceptable. Long-term follow-up and further studies are needed to confirm the role of 3D-RT or IMRT in the multimodality management of the disease.

    In order to assess the optimal management for elderly patients with localized and locally advanced prostate cancer (clinical stage: T1-T4N0M0), we reviewed the prognoses. From April 2000 to December 2008, we treated and followed up 175 patients aged 75 years, or older. In almost all of the patients above 79 years of age, endocrine therapy was selected. Among the 75 to 79-year-old patients, the proportion of radiation therapy, including external beam radiation therapy (EBRT) and high-dose-rate brachytherapy (HDR-brachytherapy), as well as radical prostatectomy increased. The follow-up period for all the patients was 0 to 106 months (median, 32 months). In the low- and intermediate-risk group, the actuarial biochemical control rate at 60 months for radical prostatectomy and endocrine therapy was 100% and 90%, respectively, and no patients with EBRT combined with endocrine therapy, and HDR-brachytherapy had biochemical failure at 34 and 46 months, respectively. In the high-risk group with 75 to 79-year-old patients, the actuarial biochemical control rate at 60 months for EBRT combined with endocrine therapy, radical prostatectomy and endocrine therapy was 71.4%, 69.0% and 55.7%, respectively, while the actuarial biochemical control rate at 48 months for HDR-brachytherapy was 40.9%. In the high-risk group with patients above 79 years of age, the actuarial biochemical control rate at 60 months for endocrine therapy was 64.5%. Prostate cancer death was recognized only in 1 patient within the high-risk group, treated by endocrine therapy. In all the patients, the overall survival rate at 60 months for EBRT combined with endocrine therapy, HDR-brachytherapy, radical prostatectomy and endocrine therapy was 100%, 100%, 76.4% and 89.5%, respectively. The actuarial biochemical control rate and overall survival rate were not significant among the management options in each risk group. However, the 75 to 79-year-old patients within the high-risk group, who were treated with

Odense C, DenmarkPurpose: Elderly cancer patients often have co-morbidities and other characteristics that make the selection of optimal treatment more complex. The introduction of targeted therapies in colorectal cancer has further complicated this problem. This review will focus on the role of the EGFR antibody cetuximab in elderly patients.Methods: We have reviewed the available evidence in the literature to evaluate the results of therapy with cetuximab, alone or in combination with chemotherapy, with a focus on elderly patients with metastatic colorectal cancer (mCRC.Results: In patients with mCRC, combination chemotherapy prolongs median survival to more than 18 months and even around 24 months in combination with cetuximab in selected patients. No prospective studies have evaluated cetuximab in elderly patients. However, subgroup analyses from randomized trials and retrospective analysis suggest that the efficacy of chemotherapy and cetuximab is maintained in fit elderly patients, but with slightly increased but acceptable toxicity.Conclusion: No prospective cetuximab studies have been conducted solely in a population of elderly patients. However, available data suggest that outcomes in the fit elderly mirror results observed in younger patients.Keywords: metastatic colorectal cancer, cetuximab, elderly patients

    Psychological responses to cancer are widely believed to affect survival. We investigated associations between hope, optimism, anxiety, depression, health utility and survival in patients starting first-line chemotherapy for metastatic colorectal cancer. Four hundred twenty-nine subjects with metastatic colorectal cancer in a randomised controlled trial of chemotherapy completed baseline questionnaires assessing the following: hopefulness, optimism, anxiety and depression and health utility. Hazard ratios (HRs) and P values were calculated with Cox models for overall survival (OS) and progression-free survival (PFS) in univariable and multivariable analyses. Median follow-up was 31 months. Univariable analyses showed that OS was associated negatively with depression (HR 2.04, P optimism, anxiety or hopefulness. PFS was not associated with hope, optimism, anxiety or depression in any analyses. Depression and health utility, but not optimism, hope or anxiety, were associated with survival after controlling for known prognostic factors in patients with advanced colorectal cancer. Further research is required to understand the nature of the relationship between depression and survival. If a causal mechanism is identified, this may lead to interventional possibilities.

For patients with disease that is refractory to fluoropyrimidines, oxaliplatin, irinotecan, and biologic agents targeting the vascular endothelial growth factor and epidermal growth factor receptor pathways, novel treatment options trifluridine/tipiracil (TAS-102 and regorafenib can be effective disease stabilizers. However, objective clinical responses are rare and toxicities are manageable but common. In order to tackle poor clinical responses to TAS-102, there is an ongoing effort to effectively combine this drug with other agents, particularly those targeting angiogenesis. Certain subpopulations appear to benefit more than others from TAS-102; those that benefit often have underlying genetic defects in DNA repair pathways and/or develop neutropenia. In this review, we focus on the role of TAS-102 in the treatment of mCRC, including its use in combination with other agents, potential predictive biomarkers of response to TAS-102, and possible future directions.

    Although Oct4 is known as a critical transcription factor involved in maintaining "stemness", its role in tumor metastasis is still controversial. Herein, we overexpressed and silenced Oct4 expression in two breast cancer cell lines, MDA-MB-231 and 4T1, separately. Our data showed that ectopic overexpression of Oct4 suppressed cell migration and invasion in vitro and the formation of metastatic lung nodules in vivo. Conversely, Oct4 downregulation increased the metastatic potential of breast cancer cells both in vitro and in vivo. Furthermore, we identified Rnd1 as the downstream target of Oct4 by ribonucleic acid sequencing (RNA-seq) analysis, which was significantly downregulated upon Oct4 overexpression. Chromatin immunoprecipitation assays revealed the binding of Oct4 to the promoter region of Rnd1 by ectopic overexpression of Oct4. Dual luciferase assays indicated that Oct4 overexpression suppressed transcriptional activity of the Rnd1 promoter. Moreover, overexpression of Rnd1 partially rescued the inhibitory effects of Oct4 on the migration and invasion of breast cancer cells. Overexpression of Rnd1 counteracted the influence of Oct4 on the formation of cell adhesion and lamellipodia, which implied a potential underlying mechanism involving Rnd1. In addition, we also found that overexpression of Oct4 led to an elevation of E-cadherin expression, even in 4T1 cells that possess a relatively high basal level of E-cadherin. Rnd1 overexpression impaired the promoting effects of Oct4 on E-cadherin expression in MDA-MB-231 cells. These results suggest that Oct4 affects the metastatic potential of breast cancer cells through Rnd1-mediated effects that influence cell motility and E-cadherin expression.

    The prognosis of patients with metastatic breast cancer is very poor. Because of this, treatment of skeletal metastasis is often palliative with limited goals rather than cure. However, there are those patients, such as presented here, who survive for an extended time. This thirty-six year old female presented with lytic lesions to one ulna and rib five years after mastectomy for breast cancer. Despite radiation and chemotherapy, the ulnar lesion expanded and resulted in an elbow dislocation. The rib lesion was resected and the arm amputated above the elbow. She developed local recurrence in both her above elbow amputation stump and chest wall and a more proximal below shoulder amputation was performed with resection of chest wall lesion. Even though she had locally aggressive disease, she has survived for 31 years after diagnosis without any evidence of disease. Reports of metastatic breast cancer survival indicate the five year survival to be 15%. There have been few reports indicating that those patients with skeletal only or oligometastatic disease have improved prognosis. It is not clear what biological properties of these tumors results in the improved survival. This case highlights the challenges of giving patients the optimal treatment in the light of limited ability to predict prognosis. It also highlights the need to further investigate the phenotypes of breast cancer that can, despite metastatic disease and with modern treatment go on to long survival. In addition this case demonstrates the importance of long term followup. Copyright © 2014 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Two-thirds of patients with metastatic cancer suffer from pain. Pain originating from skeletal metastases is the most common form of cancer-related pain. Bone pain, often exacerbated by pressure or movement, limits the patient's autonomy and social life. Pain palliation with bone-seeking radiopharmaceuticals has proven to be an effective treatment modality in patients with metastatic bone pain. These bone-seeking radiopharmaceuticals are extremely powerful in treating scattered painful bone metastases, for which external beam radiotherapy is impossible because of the large field of irradiation. 186 Re-hydroxyethylidene diphosphonate (HEDP) is a potentially useful radiopharmaceutical for this purpose, having numerous advantageous characteristics. Bone marrow toxicity is limited and reversible, which makes repetitive treatment safe. Studies have shown encouraging clinical results of palliative therapy using 186 Re-HEDP, with an overall response rate of ca. 70% in painful bone metastases. It is effective for fast palliation of painful bone metastases from various tumours and the effect tends to last longer if patients are treated early in the course of their disease. 186 Re-HEDP is at least as effective in breast cancer patients with painful bone metastases as in patients with metastatic prostate cancer. It is to be preferred to radiopharmaceuticals with a long physical half-life in this group of patients, who tend to have more extensive haematological toxicity since they have frequently been pretreated with bone marrow suppressive chemotherapy. This systemic form of radionuclide therapy is simple to administer and complements other treatment options. It has been associated with marked pain reduction, improved mobility in many patients, reduced dependence on analgesics, and improved performance status and quality of life. (orig.)

In 2008 there were an estimated 148,810 new cases and 49,960 deaths in the US. For several years different chemotherapeutic regimens, based on floropyrimidines, irinotecan and oxaliplatin, have been used in advanced CRC, but survival is still unsatisfactory. New targeted therapies, including drugs and monoclonal antibodies (MoABs , show great promise in the fight against CRC and have shown activity in different disease settings. Cetuximab, a chimeric IgG1 monoclonal antibody that binds to the extracellular domain of epidermal growth factor receptor (EGFR, is active in metastatic colorectal cancer (mCRC. As an IgG1 antibody, cetuximab may exert its antitumor efficacy through both EGFR antagonism and antibody-dependent cell-mediated cytotoxicity. The combination of this drug with classical chemotherapies has shown better clinical profiles reflected in an improvement in overall and progression-free survival. Clinical trials established the role of cetuximab, particularly with irinotecan, in irinotecan-refractory/heavily pretreated patients. Whereas cetuximab has a clear indication in the salvage setting, its role in first-line therapy remains investigational. It is particularly encouraging that cetuximab may enhance curative opportunities in patients with early metastatic disease, suggesting that adding cetuximab in first-line therapy may downstage disease in some patients, and, as a result, allow potentially curative resection of previously unresectable metastases. In this review we will focus on the main epidermal growth factor receptor inhibitors demonstrating clinical benefit, and the role of cetuximab in first-line treatment of metastatic CRC

    Mesenchymal stem cells (MSCs) transplantation has been used for therapeutic applications in various diseases. Here we report MSCs can malignantly transform in vivo. The novel neoplasm was found on the tail of female rat after injection with male rat bone marrow-derived MSCs (rBM-MSCs) and the new tumor cell line, K3, was isolated from the neoplasm. The K3 cells expressed surface antigens and pluripotent genes similar to those of rBM-MSCs and presented tumor cell features. Moreover, the K3 cells contained side population cells (SP) like cancer stem cells (CSCs), which might contribute to K3 heterogeneity and tumorigenic capacity. To investigate the metastatic potential of K3 cells, we established the nude mouse models of liver and lung metastases and isolated the corresponding metastatic cell lines K3-F4 and K3-B6. Both K3-F4 and K3-B6 cell lines with higher metastatic potential acquired more mesenchymal and stemness-related features. Epithelial-mesenchymal transition is a potential mechanism of K3-F4 and K3-B6 formation.

    BACKGROUND: Graves disease (GD) is an autoimmune condition characterized by the presence of antibodies against the thyrotropin receptor (TRAB), which stimulate the thyroid gland to produce excess thyroid hormone. Theoretically, TRAB could stimulate highly differentiated thyroid cancer tissue and...... treatment continued until after the fourth RAI dose. Hypothyroidism did not occur until following the fifth RAI treatment. SUMMARY AND CONCLUSIONS: We present a patient initially diagnosed with thyrotoxicosis and subsequently with metastatic follicular variant of papillary thyroid cancer. It is suggested...... that TRAB stimulated the highly differentiated extrathyroidal metastatic thyroid tissue to produce excessive amounts of thyroid hormone, delayed diagnosis, and potential aggravation of the course of thyroid cancer....

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

    Hepatic encephalopathy is considered a contraindication to hepatic artery embolization. We describe a patient with a well-differentiated neuroendocrine tumor metastatic to the liver with refractory hepatic encephalopathy and normal liver function tests. The encephalopathy was refractory to standard medical therapy with lactulose. The patient's mental status returned to baseline after three hepatic artery embolization procedures. Arteriography and ultrasound imaging before and after embolization suggest that the encephalopathy was due to arterioportal shunting causing hepatofugal portal venous flow and portosystemic shunting. In patients with a primary or metastatic well-differentiated neuroendocrine tumor whose refractory hepatic encephalopathy is due to portosystemic shunting (rather than global hepatic dysfunction secondary to tumor burden), hepatic artery embolization can be performed safely and effectively.

    Liver transplantation is widely accepted as an effective therapy of hepatoma. Perioperative dynamic observation of coagulation function is important for graft-receivers. This study was to explore perioperative changes of coagulation functions in the local advanced liver cancer patients who received liver transplantation. Clinical data of 31 local advanced liver cancer patients, underwent liver transplantation from Sep. 2003 to Jan. 2007, were analyzed. Platelet (PLT) counting, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (Fib) and international normalized ratio (INR) before operation, at anhepatic phase and the first week after operation were analyzed to evaluate congulation function. The coagulation functions of most patients were normal before operation. The six parameters varied significantly at anhepatic phase and on most days of the first week after operation when compared with the preoperative levels (Pfunctions of local advanced liver cancer patients shift from hypocoagulatory to hypercoagulatory or normal in perioperative period, therefore, prevention of bleeding should be focused on at anhepatic phase and on 1-2 days after operation while prevention of thrombosis should be focused on after the first week after operation. The degree of liver cirrhosis and Child-Pugh level could help to evaluate postoperative coagulation disorder.

    Metastatic ovarian tumors from colon cancer would be resistant to chemotherapy, and compromising quality of life(QOL) of these patients was caused by acute enlargement of the tumors. A 37-year-old woman with abdominal distension was diagnosed with transverse colon cancer, bilateral ovarian metastases, liver metastases, and peritoneal dissemination at prior hospital. Two courses of chemotherapy(FOLFOX)were administered, but metastaticovarian tumors enlarged. Chemotherapy was discontinued and she was referred to our institution. To achieve symptom relief, improving QOL, and to resume chemotherapy, we planned bilateral oophorectomy and primary tumor resection if other stenotic lesion was not present. As a result, we safely performed open bilateral oophorectomy and right hemi colectomy, and the patient discharged on postoperative day 11 without complications. Chemotherapy was resumed and continued for 7 months up to this time. Even though, curative resection could not be achieved, oophorectomy should be performed in patients with enlarged metastatic ovarian tumor from colon cancer, in spite of administration of chemotherapy.

    Prostate cancer (PC) is the most common cancer in Western countries. More than one third of PC patients develop metastatic disease, and the 5-year expected survival in distant disease is about 35%. During the last few years, new treatments have been launched for metastatic castrate-resistant prostate cancer (mCRPC). We aimed to review the current literature on health economic analysis on the treatment of metastatic prostate cancer (mPC), compare the studies, summarize the findings and make the results available to administrators and decision makers. A systematic literature search was done for economic evaluations (cost-minimization, cost-effectiveness, cost-utility, cost-of-illness, cost-of-drug, and cost-benefit analyses). We employed the PubMed ® search engine and searched for publications published between 2012 and 2016. The terms used were "prostate cancer", "metastatic" and "cost". An initial screening of all headlines was performed, selected abstracts were analysed, and finally the full papers investigated. Study characteristics, treatment and comparator, country, type of evaluation, perspective, year of value, time horizon, efficacy data, discount rate, total costs and sensitivity analysis were analysed. The quality was assessed using the Quality of Health Economic Studies (QHES) instrument. A total of 227 publications were detected and screened, 58 selected for full-text assessment and 31 included in the final analyses. Despite the significant international literature on the treatment of mCRPC, the
