OBJECTIVES: The inflammatory potential of diet has been inconsistently linked to colorectal cancer (CRC) risk. This meta-analysis aimed to evaluate the association of the inflammatory potential of diet, as estimated by the dietary inflammatory index (DII) score, with CRC risk. MATERIALS AND METHODS: The PubMed and Embase databases were searched for relevant studies from inception to February 2017. All cohort and case-control studies investigating the association of the DII score with CRC risk were selected...

Surgery is the mainstay curative treatment in most cancer. We aimed to test the new hypothesis that cancer surgery performed during holiday periods is associated with worse long-term prognosis than for non-holiday periods. This nationwide Swedish population-based cohort study included 228,927 patients during 1997-2014 who underwent elective resectional surgery for a cancer where the annual number of resections was over 100. The 16 eligible cancer sites were grouped into 10 cancer groups. The exposure, holiday periods, was classified as wide (14-weeks) or narrow (7-weeks)...

PURPOSE: Elevated S100A8 expression has been observed in cancers of the bladder, esophagus, colon, ovary, and breast. S100A8 is expressed by breast cancer cells as well as by infiltrating immune and myeloid cells. Here we investigate the association of elevated S100A8 protein expression in breast cancer cells and in breast tumor stroma with survival outcomes in a cohort of breast cancer patients. PATIENTS AND METHODS: Tissue microarrays (TMA) were constructed from breast cancer specimens from 417 patients with stage I-III breast cancer treated at the University of Michigan Comprehensive Cancer Center between 2004 and 2006...

BACKGROUND AND AIMS: Dysplasia within sessile serrated polyps (SSPs) is difficult to detect, may be mistaken for an adenoma risking incomplete resection of the background serrated tissue, and is strongly implicated in interval cancer after colonoscopy. The use of endoscopic imaging to detect dysplasia within SSP has not been systematically studied. METHODS: Consecutively detected SSP ≥8 mm in size were evaluated using a standardized imaging protocol at a tertiary endoscopy center over 3 years...

OBJECTIVES: Colonoscopy is widely recommended for colorectal cancer (CRC) screening, but evidence to guide the optimal frequency of repeat screening examination is limited. We examined the duration and magnitude of the risk of developing CRC, following a negative colonoscopy in those at average risk and those with a first-degree family history of CRC. METHODS: A cohort of Utah residents aged 50-80 years who had a negative colonoscopy between 1 January 2001 and 31 December 2011 was identified using the Utah Population Database...

The prevalence of colorectal cancer (CRC) in inflammatory bowel disease (IBD) is estimated at 3.7%. Risk factors for CRC include more severe disease (as reflected by the extent of disease and the duration of poorly controlled disease), family history of CRC, pseudopolyps, primary sclerosing cholangitis, and male sex. In addition, both early and late onset of IBD have been shown to be risk factors in different studies. Most societal guidelines recommend initiation of surveillance colonoscopy at 8 to 10 years after IBD symptom onset, followed by subsequent surveillance in 1- to 2-year intervals...

BACKGROUND: The use of chemotherapy among patients with stage II colon cancer is controversial. We aimed to define the utilization and factors associated with the receipt of chemotherapy and the impact of chemotherapy on long-term prognosis among a large, multiinstitutional cohort of patients. MATERIALS AND METHODS: We identified 876 patients who underwent resection for stage II colon cancer between 2004 and 2013 at one of seven participating institutions. Overall survival (OS) and recurrence-free survival (RFS) time was calculated from the date of the index procedure to the date of death...

Several epidemiological studies have investigated the relationship between height and risk of colorectal cancer (CRC), but the results were inconsistent. Thus, a meta-analysis of observational studies was carried out to clarify this association. A literature search was performed in PubMed and Web of Science databases for all relevant studies up to 25 May 2016. The random-effects model was used to calculate the pooled relative risks (RRs) and restricted cubic spline model was adopted for the dose-response analysis...

BACKGROUND: Myofascial pain that has been associated with cancer and increased risk of morbidity and mortality in cancer patients is intrinsically associated with low magnesium and low 25-hydroxyvitamin D (25(OH)D). Therefore, this physical finding was used as a clinical diagnostic proxy. OBJECTIVE: The objective of this study was to assess the association and prevalence of disease in individuals with myofascial pain and low 25(OH)D in a county with low magnesium in the drinking water...

Thermal ablation has been considered as an alternative for local curative intent in patients with unresectable colorectal liver metastases. The influence of primary tumor location on the prognosis of colorectal liver metastases patients who have undergone microwave ablation has yet to be determined. We reviewed 295 patients who underwent microwave ablation for colorectal liver metastases at our institution between March 2006 and March 2016. Univariate and multivariate analyses were performed to identify predictors of overall and progression-free survival...

Accumulating evidence demonstrates an association between dense infiltration of lymphocytes and prognosis in colorectal cancer (CRC), but whether this prognostic impact differs by tumour location remains unknown. This study investigated the prognostic impact of cytotoxic and regulatory T cells in CRC, with particular reference to the anatomical subsite of the primary tumour. The density of CD3(+) , CD8(+) , and FoxP3(+) tumour-infiltrating T cells was calculated in tissue microarrays with tumours from 557 incident CRC cases from a prospective population-based cohort...

BACKGROUND: Observational studies suggest that higher volumes of physical activity are associated with a lower risk of disease recurrence among survivors of colon cancer. However, the feasibility and safety of prescribing higher volumes of physical activity to survivors of colon cancer are unknown. Furthermore, the pathways through which exercise may reduce disease recurrence are unknown. PATIENTS AND METHODS: Survivors of stage I to III colon cancer were randomized to usual-care control, 150 minutes per week of aerobic exercise (low-dose), or 300 minutes per week of aerobic exercise (high-dose)...

MicroRNAs (miRNAs) and Transcription Factors (TFs) both influence messenger RNA (mRNA) expression, disrupting biological pathways involved in carcinogenesis and prognosis. As many miRNAs target multiple mRNAs, thus influencing a multitude of biological pathways, deciphering which miRNAs are important for cancer development and survival is difficult. In this study, we 1) determine associations between TF and survival (N = 168 colon cancer cases); 2) identify miRNAs associated with TFs related to survival; and 3) determine if factors derived from TF-specific miRNA principal component analysis (PCA) influence survival...
