PURPOSE: This study aimed to study whether cancer cells possess distinguishing metabolic features compared with surrounding normal cells, such as increased glutamine uptake. Given this, quantitative measures of glutamine uptake may reflect critical processes in oncology. Approximately, 10 % of patients with colorectal cancer (CRC) express BRAF (V600E) , which may be actionable with selective BRAF inhibitors or in combination with inhibitors of complementary signaling axes. Non-invasive and quantitative predictive measures of response to these targeted therapies remain poorly developed in this setting...

PURPOSE: Laparoscopic surgery for locally advanced colorectal cancer suspected of direct invasion to adjacent organs or structures remains controversial because of its high conversion rate, inadequate oncologic clearance and surgical outcomes. This study retrospectively evaluated the short-term outcomes of laparoscopic multivisceral resection for colorectal cancer and investigated the factors influencing conversion to open surgery. METHODS: Between 2010 and 2015, 39 patients who underwent laparoscopic multivisceral resection for colorectal cancer intraoperatively suspected of direct invasion to adjacent organs or structures were included...

BACKGROUND: Cancer is a major disease worldwide, and many patients use complementary and alternative treatments. The purpose of this study was to identify the herbal remedies and functional foods used as complementary medicine by prostate, breast and colorectal cancer patients at speciality care facilities in Trinidad. We also sought to determine how patients rated the efficacy of these modalities compared with conventional treatment. METHODS: A descriptive, cross-sectional survey was conducted using an interviewer-administered pilot-tested de novo questionnaire during the period June to August 2012 at two speciality treatment centres on the island...

BACKGROUND: Although liver resection combined with preoperative chemotherapy is expected to improve outcomes of patients with resectable colorectal liver metastasis (CRLM), there is as yet insufficient clinical evidence supporting the efficacy of preoperative systemic chemotherapy. The aim of this phase II study was to assess the feasibility and efficacy of preoperative FOLFOX systemic chemotherapy for patients with initially resectable CRLM. METHODS: A prospective multi-institutional phase II study was conducted to evaluate the feasibility and efficacy of preoperative chemotherapy for resectable CRLM (ClinicalTrials...

BACKGROUND: A principal goal for the use of positron emission tomography (PET) in oncology is for real-time evaluation of tumor response to chemotherapy. Given that many contemporary anti-neoplastic agents function by impairing cellular proliferation, it is of interest to develop imaging modalities to monitor these pathways. Here we examined the effect of capecitabine on the uptake of thymidine analogs used with PET: 3'-deoxy-3'-[(18)F]fluorothymidine ((18)F-FLT), 1-(2'-deoxy-2'-[(18)F]fluoro-β-D-arabinofuranosyl) thymidine ((18)F-FMAU), and 1-(2'-deoxy-2'-[(18)F]fluoro-β-D-arabinofuranosyl) uracil ((18)F-FAU) in patients with advanced cancer...

Colorectal liver metastasis (CRLM) is the most frequent indication for liver resection in many centers. Recent improvements in oncology, surgery, interventional radiology, pathology and anesthesiology allow curative treatment in a larger proportion of patients with CRLM. Areas covered: We illustrate the various aspects of the management of CRLM through 11 questions that summarize the topic, from the current obtained survival to future perspectives such as transplantation. The limits of a curative treatment are also presented from different angles, such as the benefits of pathology, the surgical options for extreme resections, the available chemotherapies and their efficacy, or the non-surgical ablative treatments...

BACKGROUND: Inflammatory bowel disease (IBD), comprising Crohn disease and ulcerative colitis, is a risk factor for colorectal cancer (CRC). Chemotherapy toxicity may exacerbate IBD symptoms and vice versa, but data are limited. We evaluated chemotherapy tolerance and oncologic outcomes in patients with CRC with and without IBD. PATIENTS AND METHODS: Medical records of patients with CRC with and without IBD treated between 2008 and 2013 were reviewed. Where possible, patients were matched by age, sex, stage, and diagnosis year...

Laparoscopic resection for colon and rectal cancer is associated with quicker return of bowel function, reduced postoperative morbidity rates and shorter length of hospital stay compared to open surgery, with no differences in long-term survival. Conversion to open surgery is reported in up to 30% of patients enrolled in randomized control trials comparing open and laparoscopic colorectal resection for cancer. In this review, reasons for conversion are anatomical-related factors, disease-related-factors and surgeon-related factors...

Previous studies in humans with breast, colorectal or liver cancer showed that neoplasia was associated with a modification of the blood ratio between (65) Cu and (63) Cu (∂Cu). The aim of the present study was to compare the blood ∂Cu of dogs with cancer to healthy controls or dogs with non-oncologic disease. One hundred and seventeen dogs were included in the study (35 dogs with cancer, 33 dogs with non-neoplastic disease, and 49 healthy controls). The ∂Cu of dogs with cancer was significantly lower than the ratio of healthy controls (P < 0...

PURPOSE: Do-not-resuscitate (DNR) consent is crucial in end-of-life (EOL) care for patients with advanced cancer. However, DNR consents signed by patients (DNR-P) and surrogates (DNR-S) reflect differently on patient autonomy and awareness. METHODS: This retrospective study enrolled advanced cancer patients treated at National Taiwan University Hospital, Hsin-Chu Branch between 2012 and 2014. Patients who signed DNR consent at other hospitals were excluded; the remaining patients were subsequently classified into DNR-S and DNR-P groups...

BACKGROUND: Colorectal resections are increasingly performed laparoscopically, and training in laparoscopic resections in the Netherlands has shifted from a post-residency fellowship to training in residency. The question remains if this supervised surgery affects short-term patient outcome. METHODS: Between January 2010 and July 2014, 523 consecutive patients, who underwent laparoscopic colorectal resection, were selected from a prospective single-center database...

Glutathione S-transferase omega 1 (GSTO1) is an atypical GST isoform that is overexpressed in several cancers and has been implicated in drug resistance. Currently, no small-molecule drug targeting GSTO1 is under clinical development. Here we show that silencing of GSTO1 with siRNA significantly impairs cancer cell viability, validating GSTO1 as a potential new target in oncology. We report on the development and characterization of a series of chloroacetamide-containing potent GSTO1 inhibitors. Co-crystal structures of GSTO1 with our inhibitors demonstrate covalent binding to the active site cysteine...

Rectal cancer constitutes one-third of all colorectal cancers, and the incidence in Denmark increasing. In 2012, 1.400 cases were registered, and of these 38% were located in the upper rectum. There have been several key advances in the optimal management of rectal cancer during the past decades, primarily by standardisation and improvement of the surgical procedure. There is now general agreement that the optimal surgical treatment involves the concept of total mesorectal excision and that a resection with tumour-free margins is crucial...
