BACKGROUND AND AIMS: Patients with ulcerative colitis (UC) are at risk for developing colorectal cancer (CRC), despite the development of new therapeutic agents. Stratification of the individual UC-patient's risk would be helpful to validate the risk factors for CRC. The aim of this study was to evaluate the risk factors for the development of CRC in a large cohort of patients with UC. METHODS: Data were obtained from 12 hospitals in the Kyoto-Shiga region during 2003-2013...

A major challenge for the management of advanced-colorectal-cancer is the multidisciplinary approach required for the treatment of liver metastases. Reducing the burden of liver metastases with liver-directed therapy has an important impact on both survival and health-related quality of life. This paper debates the rationale and current liver-directed approaches for colorectal liver metastases based on the evidence of literature and new clinical trials. Surgery is the gold standard, when feasible, and it's the main treatment goal for patients with potentially-resectable disease as a means of prolonging progression-free survival...

BACKGROUND: The extent of lymphadenectomy during laparoscopic right colectomy can affect the oncological outcome and the safety of surgery. The principle of complete mesocolic excision (CME) has been gradually accepted and increasingly applied by colorectal surgeons. The aim of this study is to investigate whether extended lymphadenectomy (CME) in laparoscopic colectomy could improve the oncological outcomes of patients with right-sided colon cancers, compared with D2 lymphadenectomy...

Patients with a limited number of hepatic metastases and slow rates of progression can be successfully treated with local treatment approaches(1,2). However, little is known about the heterogeneity of liver metastases, and animal models capable of evaluating the development of individual metastatic colonies are needed. Here, we present an advanced model of hepatic metastases that provides the ability to quantitatively visualize the development of individual tumor clones in the liver and estimate their growth kinetics and colonization efficiency...

BACKGROUND: The effectiveness of faecal immunochemical test (FIT)-based screening programs is highly dependent on consistent participation over multiple rounds. We evaluated adherence to FIT screening over four rounds and aimed to identify determinants of participation behaviour. METHODS: A total of 23 339 randomly selected asymptomatic persons aged 50-74 years were invited for biennial FIT-based colorectal cancer screening between 2006 and 2014. All were invited for every consecutive round, except for those who had moved out of the area, passed the upper age limit, or had tested positive in a previous screening round...

Matrix metalloproteinase-2 (gelatinase A) is a well-known mediator of cancer metastasis, but it is also thought to be involved in several aspects of cancer development, including cell growth and inflammation. In the present study, we investigate whether MMP-2 SNP, MMP-2 mRNAs, and MMP-2 protein are associated with the susceptibility to colorectal cancer in the Tunisian population. The TaqMan allele discrimination assay and DNA sequencing techniques were used for genotyping; MMP-2 expression of each genotype was analyzed by semiquantitative RT-PCR, and MMP-2 protein expression was analyzed by immunohistochemistry staining...

In recent years, the high heterogeneity of colorectal cancer (CRC) has become evident. Hence, biomarkers need to be developed that enable the stratification of patients with CRC into different prognostic subgroups and in relation to response to therapies, according to the distinctive tumour biology. Currently, only RAS-mutation status is used routinely as a negative predictive marker to avoid treatment with anti-EGFR agents in patients with metastatic CRC, and mismatch-repair status can guide the use of adjuvant chemotherapy in patients with early stage colon cancer...

Capecitabine, an oral prodrug of 5-fluorouracil (5-FU), is approved for early-stage and advanced colorectal cancer and metastatic breast cancer. Cardiotoxicity of 5-FU is well described in the literature. However, cardiac adverse effects of capecitabine are poorly described. We report a case of coronary vasospasm induced by capecitabine. A 41-year-old female with metastatic breast cancer presented with chest pain 3 days after starting capecitabine. The chest pain was relieved by rest and exacerbated by exertion...

BACKGROUND: Colorectal cancer (CRC) is associated with the modern lifestyle. Chronic alcohol consumption-a frequent habit of majority of modern societies-increases the risk of CRC. Our group showed that chronic alcohol consumption increases polyposis in a mouse mode of CRC. Here we assess the effect of circadian disruption-another modern life style habit-in promoting alcohol-associated CRC. METHOD: TS4Cre × adenomatous polyposis coli (APC)(lox468) mice underwent (a) an alcohol-containing diet while maintained on a normal 12 h light:12 h dark cycle; or (b) an alcohol-containing diet in conjunction with circadian disruption by once-weekly 12 h phase reversals of the light:dark (LD) cycle...

OBJECTIVE: Colorectal cancer (CRC) is one of the most common malignancies, associated with high rates of relapse. A notable challenge in treatment is low response rate to current therapies for advanced CRC. The miR-200c plays an essential role in tumor suppression by inhibiting epithelial-mesenchymal transition (EMT). Resveratrol, a natural compound found in red wine, reveals anti-cancer properties in several types of cancers such as CRC. The aim of current study was to evaluate the effects of resveratrol on proliferation, apoptosis and invasion of HCT-116 cells and also expression of EMT-related genes in presences or absence of miR-200c...

Previously we reported that LIM1863 colorectal cancer (CRC) cells secrete three distinct extracellular vesicle subtypes - two subpopulations of exosomes (apical EpCAM-Exos and basolateral A33-Exos) and shed microvesicles (sMVs) - with distinct protein and miRNA signatures. Here, we extend our omics approach to understand the fundamental role of LIM1863-derived EVs by performing a comprehensive analysis of their mRNAs and long non-coding RNAs (lncRNAs) using RNA-Seq. We show that 2,389 mRNAs, 317 pseudogene transcripts, 1,028 lncRNAs and 206 short non-coding RNAs selectively distributed to (i...

BACKGROUND: Combined hepatic resection and radiofrequency ablation (resection-RFA) is a widely accepted multidisciplinary treatment for unresectable colorectal cancer liver metastases. Worse prognosis after resection-RFA is correlated to tumor morphology, although unfavorable morphology is inherent to this patient cohort. This study aimed to select patients who may or may not benefit from resection-RFA with the aid of tumor biology. METHOD: Data from 485 patients who underwent curative hepatectomy with or without concurrent RFA were retrospectively collected and analyzed...

Stereotactic Body Radiotherapy (SBRT) is a well established therapeutic option for patients affected with peripheral early stage non-small cell lung cancer (NSCLC), given the positive clinical evidence accumulated so far on its efficacy and safety. SBRT is regarded as the best choice for inoperable patients, and could also be offered as an alternative to surgery to selected operable patients. More recently, its use for lung metastases progressively increased, and SBRT is now regarded as a low toxic and highly effective local therapy for lung oligometastases from different primary tumors, especially colorectal cancer...
