AIM: With consideration of the theoretical link between the stent insertion and the increased risk of tumor cells spillaged, which may lead to distant metastases, there is a concern about long-term clinical outcomes after the usage of self-expanding metallic stents (SEMS) as a "bridge to surgery" in the malignant colorectal obstruction (MCO) treatment. This cohort study aimed to compare the long-term oncological outcomes of SEMS as a bridge to surgery (SEMS group) with those of emergency surgery (ES group) for MCO...

BACKGROUND: Preoperative skeletal muscle depletion or sarcopenia has been suggested to predict worse outcome after resection of colorectal liver metastases. The aim of the present study was to investigate the impact of neoadjuvant chemotherapy on preoperative skeletal muscle mass prior to liver resection. METHODS: Patients operated with liver resection for colorectal liver metastases between 2010 and 2014 were retrospectively reviewed. Muscle mass was evaluated by measuring muscle area on a cross-sectional computed tomography image at the level of the third lumbar vertebra, and normalized for patient height, presenting a skeletal muscle index...

Bevacizumab is a humanized monoclonal antibody targeting vascular endothelial growth factor (VEGF). Recurrence after resection of colorectal liver metastases (CRLMs), presumably caused by VEGF-mediated outgrowth of micrometastases, might decrease when VEGF is inhibited. This study examines the efficacy and safety of adding bevacizumab to an adjuvant regimen of CAPOX in patients undergoing radical resection for their CRLMs. Patients with resected CRLMs were randomized after surgery to receive CAPOX and bevacizumab (arm A) or CAPOX alone (arm B) as adjuvant treatment...

SIRT2 is involved in the development of a variety of cancers. Shikonin is a natural compound that is known to have antitumour effects. This study aims to assess the effects of shikonin on the development and metastatic progression of colorectal cancer (CRC) through regulation of SIRT2 expression and whether this effect is related to the phosphorylation of extracellular signal-regulated kinases (ERKs). The results demonstrated that SIRT2 is downregulated in CRC biopsy samples (n = 31) compared with the adjacent non-cancerous tissues (ANCT, n = 26)...

Colorectal cancer (CRC) is a malignant disease whose incidence and mortality rates are greatly influenced by environmental factors. Under-treatment of CRC such as a poor diagnostic evaluation, less aggressive surgery, less intensive chemotherapy results in metastasizing of the primary tumor cells and recurrence of cancer. Prolonged chemotherapy treatment against cancer is hazardous to the patients, which also limits its use in cancer therapy. Current research in developing a novel anti-cancer agent, direct towards finding a better anti-metastatic and an anti-invasive drug with reduced side effects...

Despite rare, metastatic anal carcinoma confers a poor prognosis. Systemic chemotherapy is the mainstay of treatment for advanced disease while the role of biologics and/or surgical resection of metastatic disease are anecdotal. Compared to isolated liver colorectal or neuroendocrine cancer liver metastases, there is far less experience with resection or nonsurgical local ablative procedures for patients with metastatic anal carcinoma to the liver. We report the case of a 67-year-old woman with metastatic anal carcinoma to the liver who was successfully treated with liver resection and remains free of relapse more than one year later...

BACKGROUND: Colorectal cancer is a leading cause of cancer-related mortality, has a very broad mutational spectrum, and there is no clinically available biomarker that can predict which patients with stage II or stage III colorectal cancer will develop metastatic disease. PATIENTS AND METHODS: We used a targeted next-generation sequencing approach to analyze the mutational spectra in stage II and III colon cancer patient samples. RESULTS: Amidst a broad range of acquired mutations and variants, we found evidence of tumor heterogeneity that distinguished the tumors in different groups...

INTRODUCTION: It is rare for a patient to present with adrenal insufficiency secondary to bilateral adrenal metastases from a malignant colorectal tumor. CASE PRESENTATION: An 82-year-old Japanese man presented to our hospital with high fever and malaise. He was receiving oral chemotherapy for the treatment of rectal cancer with multiple metastases. Computed tomography showed new bilateral adrenal gland metastases. A rapid adrenocorticotropic hormone (ACTH) test showed adrenal insufficiency...

PURPOSE: Optimal patient selection for stereotactic radiosurgery (SRS) as the initial treatment for brain metastases is complicated and controversial. This study aimed to develop a nomogram that predicts survival without salvage whole brain radiation therapy (WBRT) after upfront SRS. METHODS AND MATERIALS: Multi-institutional data were analyzed from 895 patients with 2095 lesions treated with SRS without prior or planned WBRT. Cox proportional hazards regression model was used to identify independent pre-SRS predictors of WBRT-free survival, which were integrated to build a nomogram that was subjected to bootstrap validation...

INTRODUCTION: Pulmonary metastases occur in up to 25% of colorectal cancer (CRC) patients. Many studies have reported that pulmonary metastasectomy might increase 5-year survival of these patients. The aim of this study was to describe our experience with pulmonary metastasectomy for metastatic colorectal cancer and to explore the prognostic value of serum C-reactive protein (CRP) and other factors. METHODS: Between June 2002 and December 2013, the clinicopathological data of 88 patients who underwent resection of pulmonary metastases from colorectal carcinoma were retrospectively reviewed and analyzed...

BACKGROUND: Preoperative neoadjuvant therapy for colorectal liver metastases (CRLM) is increasing in use and can lead to chemotherapy-induced damage to sinusoidal integrity, namely sinusoidal obstruction syndrome (SOS). SOS has been associated with an increased need for intraoperative blood transfusions, increased length of hospitalization post-surgery, decreased tumor response, and a shorter overall survival after resection due to liver insufficiency. It is critical for clinicians and pathologists to be aware of this type of liver injury, and for pathologists to include the status of the background, non-neoplastic liver parenchyma in their pathology reports...

Breast cancer is the leading cause of cancer-related mortality in women worldwide. Liver metastasis is involved in upwards of 30% of cases with breast cancer metastasis, and results in poor outcomes with median survival rates of only 4.8 - 15 months. Current rodent models of breast cancer metastasis, including primary tumor cell xenograft and spontaneous tumor models, rarely metastasize to the liver. Intracardiac and intrasplenic injection models do result in liver metastases, however these models can be confounded by concomitant secondary-site metastasis, or by compromised immunity due to removal of the spleen to avoid tumor growth at the injection site...

INTRODUCTION: Surgical resection offers the best chance of cure for patients with colorectal liver metastases (CRLMs). Two-stage hepatectomy (TSH) has been demonstrated to be safe and effective to obtain curative resection in patients with multiple, bilobar CRLMs that are unresectable in a single procedure. Up to now TSH has been the prerogative of dedicated liver surgery centers. The aim of this study was to assess the safety and effectiveness of TSH also in community hospitals. METHODS: Of 294 patients operated on for CRLMs between September 1997 and June 2012 in 2 district community hospitals (belonging to the same regional healthcare district), 43 (14...

BACKGROUND: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is an effective treatment for colorectal peritoneal metastases (CPM), increasing overall survival in selected patients. The aim of this systematic review was to assess the effect of neoadjuvant and adjuvant systemic chemotherapy on overall survival in patients with CPM undergoing CRS and HIPEC, compared with those who receive CRS and HIPEC alone. METHODS: A systematic literature review was performed using the PubMed database, and the preferred reporting items for systematic reviews and meta-analyses guidelines formed the structure of the review...

PURPOSE: The purpose of this study was to assess hepatic arterial infusion (HAI) of oxaliplatin combined with intravenous 5-fluorouracil (5-FU) and l-leucovorin (l-LV) in colorectal cancer (CRC) patients with systemic chemotherapy failure in a phase I/II trial. METHODS: CRC patients with unresectable liver metastases following standard systemic chemotherapy failure were eligible. A catheter-port system for HAI was placed using interventional radiology. In phase I, escalating doses of oxaliplatin for levels 1 and 2 were set at 50 and 100 mg/m(2), respectively, and were combined with fixed doses of intravenous 5-FU (200 mg/m(2) bolus and 2400 mg/m(2)/46-h continuous infusion) and l-LV (200 mg/m(2))...
