Efficacy of proximal colectomy for surgical management of right-sided first colorectal cancer in Lynch Syndrome mutation carriers

ConclusionRisk of subsequent CRC and survival estimates following PC and TC + STC should be considered in surgical management of right-sided first CRC in LS mutation carriers.

CONCLUSION:  LS colonic and extracolonic clinical management, surveillance and therapy are complex and several aspects remain unclear. In the future, surveillance and clinical management need to be more tailored to gene and gender. Future prospective trials are needed. PMID: 31739377 [PubMed - in process]

Publication date: Available online 21 August 2019Source: Journal of Visceral SurgeryAuthor(s): B. Menahem, A. Alves, J.M. Regimbeau, C. SabbaghSummaryNearly 5% of colorectal cancers are related to constitutional genetic abnormalities. In Lynch Syndrome (LS), the abnormality is a mutation of the deoxyribonucleic acid (DNA) repair system. The goal of this update is to update indications and surgical strategies for patients with LS. Different spectra of disease are associated with LS. The narrow spectrum includes cancers with a high relative risk: colorectal cancer (CRC), endometrial cancer, urinary tract cancers and small in...

We report a case of a 62 year old man, diagnosed with MSH2-Lynch syndrome, who underwent successful eFTR treatment of an early (pT1) colon cancer located in the ascending colon, with no signs of recurrence 12 months after treatment. We discuss the pros and cons of endoscopic re section of early colorectal carcinoma in Lynch syndrome patients.

ConclusionsWe conclude that TAC as the primary surgical option for LS patients diagnosed with Stage I-III colon cancer is cost-effective. Further cost-effectiveness study is recommended to include extra-colonic malignancies in LS patients.

Case Summary: A 56-year-old man with a history of hypertension and hyperlipidemia was referred by gastroenterology for bleeding per rectum. Because of a family history of colon cancer, he had several prior colonoscopies, most recently 3 years ago, without evidence of pathology. His mother was diagnosed with colon cancer in her mid-40s. His current colonoscopy demonstrated a 2.4 × 1.5 cm cecal adenocarcinoma. Staging workup revealed no evidence of metastatic disease. Because of the patient’s family history, the specimen was further evaluated and found to have high microsatellite instabilit...

AbstractAround 5% of colorectal cancers are due to mutations within DNA mismatch repair genes, resulting in Lynch syndrome (LS). These mutations have a high penetrance with early onset of colorectal cancer at a mean age of 45  years. The mainstay of surgical management is either a segmental or extensive colectomy. Currently there is no unified agreement as to which management strategy is superior due to limited conclusive empirical evidence available. A systematic review and meta- analysis to evaluate the risk of metach ronous colorectal cancer (MCC) and mortality in LS following segmental and extensive colectomy. A s...

CONCLUSIONS: The finding of a dMMR CRC had consequences for decisions on chemotherapy in a relative high proportion of patients. We recommend testing in all patients with CRC independent of age at diagnosis, as proper treatment decisions and genetic counselling are very important.
