Colorectal Cancer Screening in the Elderly.
Abstract Colorectal cancer (CRC) is a common and preventable malignancy, and routine CRC screening is recommended for average risk individuals between the ages of 50 and 75 years. Screening has been shown to decrease CRC incidence and mortality. Once patients are older than 75 years, the risk to benefit ratio of ongoing screening begins to shift. As comorbidities increase and life expectancy decreases, the future potential benefits of CRC prevention become less robust, and risk for screening-related complications grows. However, firm age cutoffs are not sufficient to guide these decisions, as there is substantial ...

Use of bioelectrical impedance analysis to monitor changes in fat-free mass during recovery from colorectal cancer- a validation study.
CONCLUSION: In a well-nourished population of non-metastatic CRC patients, a single-frequency whole-body BIA device yielded imprecise data on changes in FFM, regardless of equation. BIA is thus not a valid option for quantifying changes in FFM in individuals. However, BIA could be used to identify patients with loss in FFM ≥5% in this population. The validity of BIA to monitor changes in FFM warrants further investigation before implementation in clinical praxis. PMID: 33183537 [PubMed - in process] (Source: Clinical Colorectal Cancer)

Risk of Colon Cancer and Recommended Surveillance Strategies in Patients with Ulcerative Colitis.
This article summarizes key strategies for colonoscopic surveillance, the most widely used and evidence-based method of CRC prevention. As currently constituted and practiced, surveillance examinations every 1 to 3 years with lesion detection and removal using high-definition endoscopic systems with or without pancolonic spray-dye chromoendoscopy is the best method for mitigating the development of CRC morbidity and mortality. For patients with primary sclerosing cholangitis with UC, surveillance should begin at the time of diagnosis and colonoscopy should be performed annually. PMID: 33121696 [PubMed - in process] (S...

A persistent high neutrophil-to-lymphocyte ratio predicts poor prognosis in patients with colorectal cancer undergoing resection.
Abstract The prognostic role of the neutrophil-to-lymphocyte ratio (NLR) has been reported in colorectal cancer (CRC); however, its variation and corresponding predicative value in patients undergoing resection remain largely unknown. In the present study, data from 146 patients with CRC were retrospectively collected, optimal cut-off points for preoperative and postoperative low and high NLRs were set, and ΔNLR was calculated. Subsequently, patients were classified into low-low, low-high, high-low and high-high subgroups based on the cut-off points, and their progression-free survival (PFS) was determined. ...

Stoma closure and reinforcement (SCAR): A study protocol for a pilot trial.
Abstract A quality metric for centers performing rectal cancer surgery is a high percentage of sphincter sparing procedures. These procedures often involve temporary bowel diversion to minimize the complications of an anastomotic leak. The most common strategy is a diverting loop ileostomy which is then closed after completion of adjuvant therapy or the patient recovers from surgery. Loop ileostomy is not without complications and the closure is complicated by a one in three chance of incisional hernia development. Strategies to prevent this problem have been designed using a variety of techniques with and without...

Abstract Colorectal cancer incidence and mortality have decreased in the United States in recent decades, largely through opportunistic screening. Although certain organizations have improved internal screening rates by implementing programmatic screening, most of the United States undergoes opportunistic screening. Much effort and resources have been expended comparing screening tests to determine the most effective; however, deeper analysis of the US population has revealed subsets of ethnicities may be grossly underscreened. The most effective screening test remains the test that is completed and adhered to, an...

Colorectal Cancer in Persons Under Age 50: Seeking Causes and Solutions.
Abstract Early onset colorectal cancer (EOCRC) refers to colorectal cancer (CRC) in individuals under age 50. Although the incidence and mortality due to later onset CRC (≥50 years) has been declining over several decades, both are increasing in those under 50. EOCRC is more likely to occur in the distal colon and rectum. There are some unique pathologic and genetic features to these tumors; they are not usually associated with a germline mutation in a gene that predisposes to cancer, and at least some may have a distinct pathogenesis. Initiating CRC screening at an earlier age (40-45 years of age) would p...

Colorectal Cancer Screening for the Serrated Pathway.
Abstract Serrated polyps are classified into hyperplastic polyps, sessile serrated adenomas/polyps, and traditional serrated adenomas. Although all serrated polyps share characteristic colonic crypts serrations, distinguishing hyperplastic polyps from sessile serrated adenomas/polyps is challenging. Traditional serrated adenomas are cytologically dysplastic lesions; sessile serrated adenomas/polyps develop cytologic dysplasia as they progress to colorectal cancer. A flat and pale appearance of serrated polyps may make detection difficult. Endoscopic mucosal resection has higher rates of complete resection. Close s...

Abstract The goal of colorectal cancer (CRC) screening with colonoscopy is to minimize CRC with minimal risk and cost. In order to continuously improve the quality of colonoscopy, different outcomes must be measured. For this topic, the priority indicators to be measured are (1) frequency of scheduling colonoscopy at appropriate interval based on current guidelines; (2) frequency of identifying adenomas in average-risk individuals undergoing their first screening colonoscopy; and, (3) providing guideline-consistent recommendations for repeat colonoscopy after the procedure.

Evidenced-Based Screening Strategies for a Positive Family History.
Abstract The most commonly recognized high-risk group for colorectal cancer (CRC) is individuals with a positive family history. It is generally recognized that those with a first-degree relative (FDR) with CRC are at a 2-fold or higher risk of CRC or advanced neoplasia. FDRs of patients with advanced adenomas have a similarly increased risk. Accordingly, all major US guidelines recommend starting CRC screening by age 40 in these groups. Barriers to screening this group include patient lack of knowledge on family and polyp history, provider limitations in collecting family history, and insufficient application of ...

Block of proliferation 1 promotes cell migration and invasion in human colorectal cancer cells via the JNK pathway.
In this study, the results of immunohistochemistry showed that BOP1 was upregulated in our cohort of CRC patients. BOP1 knockdown inhibited the migration and invasion of CRC cells, confirmed by the downregulation of the mRNA levels of MMP-2 and MMP-9. The overexpression of BOP1 in CRC cells exerted the opposite effect. SP600125, an inhibitor of JNK signaling, partially abolished the BOP1 overexpression-mediated increase in the migratory and invasive ability of CRC cells. Our results indicated that BOP1 is an important regulator of CRC cell invasion and migration, predominantly through the JNK signaling pathway. PMID: ...

Cetuximab versus bevacizumab in metastatic colorectal cancer: a comparative effectiveness study.
CONCLUSION: This study provides evidence suggesting bevacizumab and cetuximab lead to similar effectiveness outcomes in mCRC, except for right-sided tumours, where cetuximab seemed to show considerably poorer outcomes. Further research is needed to confirm these results. PMID: 32144533 [PubMed - as supplied by publisher] (Source: Clinical Colorectal Cancer)

SEPT9_v2, frequently silenced by promoter hypermethylation, exerts anti-tumor functions through inactivation of Wnt/ β-catenin signaling pathway via miR92b-3p/FZD10 in nasopharyngeal carcinoma cells.
CONCLUSIONS: This study delineates SEPT9_v2, frequently silenced by promoter hypermethylation, exerts anti-tumor functions through inactivation of the Wnt/β-catenin signaling pathway via miR92b-3p/FZD10 in nasopharyngeal carcinoma cells and, hence, SEPT9_v2 may be a promising therapeutic target and biomarker for nasopharyngeal carcinoma.

Colorectal cancer statistics, 2020.
Abstract Colorectal cancer (CRC) is the second most common cause of cancer death in the United States. Every 3 years, the American Cancer Society provides an update of CRC occurrence based on incidence data (available through 2016) from population-based cancer registries and mortality data (through 2017) from the National Center for Health Statistics. In 2020, approximately 147,950 individuals will be diagnosed with CRC and 53,200 will die from the disease, including 17,930 cases and 3,640 deaths in individuals aged younger than 50 years. The incidence rate during 2012 through 2016 ranged from 30 (per 10...

Colorectal cancer in the United States and a review of its heterogeneity among Asian American subgroups.
Abstract Colorectal cancer is the third most common cancer in the United States. Established risk factors include older age, unhealthy lifestyle (high consumptions of red/preserved meat, low consumptions of fruit and vegetables, smoking, high alcohol consumption, and lack of physical activities), personal and family medical histories and low socioeconomic status (low insurance coverage, education and income). Asian American subgroups vary significantly in terms of culture, socioeconomic status, and health behaviors, yet most registries and researches aggregate all Asian Americans as one group. In this review, we s...

Variations in clinical features and oncologic behaviors of T1 colorectal cancer according to tumor location.
Abstract BACKGROUND: Different genetic characteristics according to tumor location result in variations in survival rates and treatment responses in advanced colorectal cancer (CRC). However, the effects of tumor location during early CRC are still unclear. METHODS: Patients with T1 CRC treated between 2003 and 2019 were enrolled from a prospectively collected database. Patients were once divided into four groups, then combined into two groups (right- and left-sided CRC) according to the tumor location, and clinical features and oncologic behaviors were compared. RESULTS: In total, 458 patients were anal...
