Clinicopathological features and oncological outcomes of patients with young-onset rectal cancer.

Clinicopathological features and oncological outcomes of patients with young-onset rectal cancer. Br J Surg. 2020 Mar 09;: Authors: Zaborowski AM, Murphy B, Creavin B, Rogers AC, Kennelly R, Hanly A, Martin ST, O'Connell PR, Sheahan K, Winter DC Abstract BACKGROUND: The incidence of rectal cancer among adults aged less than 50 years is rising. Survival data are limited and conflicting, and the oncological benefit of standard neoadjuvant and adjuvant therapies is unclear. METHODS: Disease-specific outcomes of patients diagnosed with rectal cancer undergoing surgical resection with curative intent between 2006 and 2016 were analysed. RESULTS: A total of 797 patients with rectal cancer were identified, of whom 685 had surgery with curative intent. Seventy patients were younger than 50 years and 615 were aged 50 years or more. Clinical stage did not differ between the two age groups. Patients aged less than 50 years were more likely to have microsatellite instability (9 versus 1·6 per cent; P = 0·003) and Lynch syndrome (7 versus 0 per cent; P

AbstractThe aims of the Prospective Lynch Syndrome Database (PLSD) are to provide empirical prospectively observed data on the incidences of cancer in different organs, survival following cancer and the effects of interventions in carriers of pathogenic variants of the mismatch repair genes (path_MMR) categorized by age, gene and gender. Although PLSD is assumption-free, as with any study the ascertainment procedures used to identify the study cohort will introduce selection biases which have to be declared and considered in detail in order to provide robust and valid results. This paper provides a commentary on the method...

PB, Shia J, Schultz N, Garcia-Aguilar J, Diaz LA, Goodman K, Saltz LB, Weiser MR, Smith JJ, Stadler ZK Abstract PURPOSE: Evaluate response of mismatch repair deficient (dMMR) rectal cancer to neoadjuvant chemotherapy. EXPERIMENTAL DESIGN: dMMR rectal tumors at Memorial Sloan Kettering were retrospectively reviewed for characteristics, treatment, and outcomes. Fifty dMMR rectal cancer patients were identified by immunohistochemistry and/or microsatellite instability analysis, with initial treatment response compared to a matched pMMR rectal cancer cohort. Germline and somatic mutation analyses were evaluated....

ConclusionThe patient presented represents the first reported case where both next generation sequencing (NGS) forBRCA LOH and MMR IHC testing of her breast cancer were performed and underscores the importance of using NGS including the reported mutational allelic frequency (MAF) and IHC use to predict the likely responsiveness to the recently approved PARP inhibitors and checkpoint inhibitor therapies (Robson et al in N Engl J Med 377:523 –533, 2017, Lemery et al in 377(15):1409–1412,https://doi.org/10.1056/NEJMp1709968, 2017), key because the gatekeeper transforming event for tumors related to inherited cance...

ConclusionsResults of the Idylla ™ MSI Assay were highly concordant with results of routine tests and lower failure rates were observed. Further advantages are the lack of need for matched normal tissue, the low dependence on pre-analytical conditions, the simplified workflow, the short turnaround times, the automated result inte rpretation, and the very limited hands-on work.Editorial acknowledgementTeams involved in the MSI, Idylla MSI Assay, Colon Rectal Cancer, Multicenter Study.Legal entity responsible for the studyIrblleida.FundingBiocartis.DisclosureX.

ConclusionsThe ‘pelvis-first’ approach to proctectomy is advantageous for patients with a highly redundant sigmoid colon. Transabdominal division of the levator ani during APR ensures excellent circumferential margin. Although Lynch syndrome-associated rectal cancer can show excellent response to NCRT,3 patients undergoing watchful delay of surgery require close monitoring and prompt triggering of salvage proctectomy when tumor regrowth is observed.4,5

CONCLUSION: The combination of an increasing incidence of colorectal cancer in those under 50 years of age and the predominance of left-sided cancer suggests that screening by flexible sigmoidoscopy starting at age 40 in average-risk individuals may prevent cancer by finding asymptomatic lesions.

A new study released by the National Cancer Institute shows colon and rectal cancers have increased dramatically and steadily in young and middle-age adults in the United States over the past four decades. Dr. Yixing Jiang, a Medical Oncologist at the University of Maryland Greenebaum Comprehensive Cancer Center, answers all the questions you’re now asking yourself about colon cancer. Q. What are the risk factors for colon cancer? A. The risks for developing colon cancer are: obesity; insulin resistance diabetes, red and processed meat; tobacco; alcohol; family history of colorectal cancer; certain hereditary syndrom...

Inflammatory bowel disease (IBD), consisting mainly of ulcerative colitis and Crohn's disease (CD), is characterized by chronic inflammation of the colon (and in the case of CD, other parts of the GI tract). As such, it is often considered the prototypical model of inflammation-associated carcinogenesis. After the well-known genetic syndromes that greatly predispose individuals to colorectal cancer (CRC), such as Lynch Syndrome and familial adenomatous polyposis (FAP), IBD is considered the third most common cause of high-risk CRC. Curiously, colitis-associated CRC (so-called CAC) shares several clinicopathological feature...

Chemoprevention offers an attractive option to prevent the occurrence of cancer in high risk cancer syndromes, such as familial adenomatous polyposis (FAP) and Lynch syndrome. However, data, especially from clinical trials, is sparse. This presentation will review the state of art concepts of chemoprevention in regards to these hereditary GI cancer syndromes.Lynch Syndrome: In the randomized CAPP2 trial, 861 participants with Lynch syndrome took either daily aspirin (600 mg) or placebo for up to 4 years; the primary endpoint was the development of CRC (1). After a mean follow-up of 55.7 months, participants taking daily as...

Conclusions: The CCFR has shed light on many environmental factors, genetics and tumor characteristics that are related to both incidence and survival. Information gained from studies using this resource provides insight into the biology of this common cancer and importantly may help target messaging on prevention, inform the development of interventions, or tailor recommendations for CRC survivorship care. The greater scientific community has access to this rich resource.Citation Format: Polly A. Newcomb.
