BACKGROUND: Some prior studies have reported reduced colorectal cancer risk among individuals using antidepressant (AD) medications, especially selective serotonin reuptake inhibitors (SSRIs). Yet, most studies have not considered the potential role of depression or other confounders in their analyses. METHODS: We utilized prospectively collected data from 145,190 participants in the Women's Health Initiative, among whom 2,580 incident colorectal cancer cases were diagnosed...

The NCCN Guidelines for Rectal Cancer are now more closely aligned with those for colon cancer. A new MRI-based definition of the rectum has been included and the use of MRI in staging has been elevated in importance. There is a new emphasis on neoadjuvant therapy, especially the concurrent use of chemotherapy and radiotherapy. One of the biggest changes is more acceptance of an observational approach-"watch and wait, nonoperative management"-for select patients experiencing a complete clinical response with no evidence of residual disease after neoadjuvant therapy...

Approximately 30% of patients with ulcerative colitis require a colectomy during their disease course. This substantially reduces colorectal cancer risk, although it is still possible to develop colorectal neoplasia in the remaining rectum. Although clear and well-accepted surveillance guidelines exist for patients with inflammatory bowel disease with an intact colon, specific surveillance recommendations following colectomy are less clear. Here, we aim to summarize the prevalence, incidence, and risk factors for developing colorectal cancer in patients with inflammatory bowel disease who underwent subtotal colectomy with a permanent end ileostomy and rectal stump, or with ileorectal anastomosis...

OBJECTIVES: The aim of this study is to investigate the effect of age on patient outcome after colorectal carcinoma (CRC) resection in patients over 65 years of age. METHODS: This study included patients aged 65 years and older who underwent CRC resection between 2003 and 2013 at a single-center institution. Patients were divided into two groups: Group A (65-74 years old) and Group B (≥75 years old). RESULTS: Multivariable logistic analysis of 415 patients revealed serum albumin levels on the third postoperative day (POD) (Odds Ratio (OR), 0...

BACKGROUND: National databases show a recent significant increase in the incidence of colorectal cancer in people younger than 50. With current recommendations to begin average-risk screening at age 50, these patients do not have the opportunity to be screened. We hypothesized that most of the cancers among the young would be left sided, which would create an opportunity for screening the young by flexible sigmoidoscopy. OBJECTIVE: This study aims to analyze the anatomic distribution of sporadic colorectal cancers in patients under the age of 50...

According to World Cancer Research Fund International/American Institute for Cancer Research, it is 'probable' that dairy products decrease the risk of colorectal cancer (CRC). However, meta-analyses restricted to women have not shown associations between milk intake and risk of CRC. The aim of this study was to examine the association between milk intake and risk of CRC, colon cancer and rectal cancer among women. Data from 81 675 participants in the Norwegian Women and Cancer Cohort Study were included, and multivariable Cox proportional hazard regression models were used to investigate milk intake using two different analytical approaches: one that included repeated measurements and one that included baseline measurements only (872 and 1084 CRC cases, respectively)...

Polyphenols may play a chemopreventive role in colorectal cancer (CRC); however, epidemiological evidence supporting a role for intake of individual polyphenol classes, other than flavonoids is insufficient. We evaluated the association between dietary intakes of total and individual classes and subclasses of polyphenols and CRC risk and its main subsites, colon and rectum, within the European Prospective Investigation into Cancer and Nutrition (EPIC) study. The cohort included 476,160 men and women from 10 European countries...

The epidemiological evidence demonstrating the effect of disinfection by-products (DBPs) from drinking water on colon and rectal cancers is well documented. However, no systematic assessment has been conducted to assess the potential effect measure modification (EMM) in the relationship between DBPs and cancer. The objective of this paper is to conduct a systematic literature review to determine the extent to which EMM has been assessed in the relationship between DBPs in drinking water in past epidemiological studies...

Background: Colon and rectal gastrointestinal stromal tumors (GISTs) are rare and poorly characterized. Because the majority of treatment guidelines for GISTs are extrapolated from tumors of gastric and small bowel origin, our aim was to better characterize the unique clinicopathologic features and prognostic factors of colon and rectal GISTs to guide clinical care. Methods: The National Cancer Data Base (NCDB) was queried from 2006 to 2013 for cases of GISTs in the stomach, colon, and rectum...

Background: Numerous studies have shown that miRNA levels are closely related to the survival time of patients with colon, rectal, or colorectal cancer (CRC). However, the outcomes of different investigations have been inconsistent. Accordingly, a meta-analysis was conducted to study associations among the three types of cancers. Materials and methods: Studies published in English that estimated the expression levels of miRNAs with survival curves in CRC were identified until May 20, 2017 by online searches in PubMed, Embase, Web of Science, and the Cochrane Library by two independent authors...

We investigated whether obesity and socio-demographic factors at adolescence are associated with incident gastroenteropancreatic neuroendocrine tumors (GEP-NET).Our cohort included 2.3 million Israeli adolescents examined at ages 16 to 19 years between 1967 and 2010. The baseline database included sex, country of birth, residential socio-economic status (SES), body-mass index (BMI) and height. Participants were followed through linkage with the National Cancer Registry up to 2012. We identified 221 cases of GEP-NET (66 pancreatic, 52 gastric, 39 rectal, 27 appendiceal, 23 small bowel and 14 colonic)...

INTRODUCTION: We assessed the radiosensitivity of lung metastases based on primary histology using a validated gene signature and model lung metastases for the genomically adjusted radiation dose (GARD). METHODS: Tissue samples were identified from our prospective observational protocol. The radiosensitivity index (RSI) 10 gene assay was run on samples and calculated alongside GARD using the previously published algorithms. A cohort of 105 patients with 137 lung metastases treated with SBRT at our institution was used for clinical correlation...

Colorectal cancer (CRC) is one of the major causes of cancer-associated mortality worldwide. The currently approved therapeutic agents show a rather limited efficacy. We have recently demonstrated that the atypical cadherin FAT1 is a specific marker of CRC and that the FAT1-specific monoclonal antibody mAb198.3 may offer new therapeutic opportunities for CRC, being efficiently internalized by cancer cells and reducing cancer growth in colon cancer xenograft models. In this study we explored the therapeutic efficacy of mAb198...

Background: Emergency general surgery patients are at significant risk of postoperative complications and mortality compared with their elective counterparts. Although challenged by some studies, increasing evidence shows that emergency colectomy for cancer is associated with worse early postoperative and long-term outcomes. Methods: We have included all patients with colon cancer admitted to the Emergency Hospital of Bucharest between January 2011 and January 2016. SELECTION CRITERIA: (1) colon tumor; (2) left-sided localization of the tumor; (3) pathology exam revealing adenocarcinoma...

Inflammatory bowel diseases, which are multifactorial autoimmune colitis diseases, are occurring with increasing prevalence. One of the most serious complications of these diseases is colorectal cancer. Here we investigated the role of periostin (Postn), a matricellular protein that interacts with various integrin molecules on the cell surface, in colitis-induced colorectal cancer. Immunohistochemistry of mouse and human colorectal cancer samples revealed that Postn was expressed in the stroma and was upregulated in close proximity to the cancer cells...

MicroRNAs (miRNAs) are post-transcriptional regulators of gene expression that target mRNAs for translational repression or cleavage. The present study was conducted to identify differentially expressed miRNAs in primary tumor tissues of rectal carcinoma (RC) that may be associated with heterochrony hepatic metastasis (HHM). Samples were collected exclusively from patients with RC but not colon cancer (CC); Next-generation high-throughput sequencing technology and bioinformatics tools were used to profile and analyze small RNAs and their corresponding targets in primary tumor tissues with HHM (n=2) or without metastases (non-metastatic, NM; n=2)...
