ConclusionTo optimize targeting and visualization of the surgical field in right pelvic sidewall/paracolic gutter, robotic arms can be placed in a straight line from above the pubic symphysis extending to the left subcostal line and between the midline vertical and midclavicular lines. Robotic tumor debulking should be considered in selected patients with recurrent ovarian cancer who present with oligo-metastatic disease, in the absence of carcinomatosis.

Tougeron Tumor DNA mismatch repair (MMR) deficiency testing is important to the identification of Lynch syndrome and decision making regarding adjuvant chemotherapy in stage II colorectal cancer (CRC) and has become an indispensable test in metastatic tumors due to the high efficacy of immune checkpoint inhibitor (ICI) in deficient MMR (dMMR) tumors. CRCs greatly benefit from this testing as approximately 15% of them are dMMR but only 3% to 5% are at a metastatic stage. MMR status can be determined by two different methods, microsatellite instability (MSI) testing on tumor DNA, and immunohistochemistry of the MMR pro...

AbstractBackgroundWe previously reported that in pathogenic mismatch repair (path_MMR) variant carriers, the incidence of colorectal cancer (CRC) was not reduced when colonoscopy was undertaken more frequently than once every 3 years, and that CRC stage and interval since last colonoscopy were not correlated.MethodsThe Prospective Lynch Syndrome Database (PLSD) that records outcomes of surveillance was examined to determine survival after colon cancer in relation to the time since previous colonoscopy and pathological stage. Onlypath_MMR variants scored by the InSiGHT variant database as class 4 or 5 (clinically actionable...

ConclusionsRobotic resection of the tumor nodule off the external iliac vessels was successfully performed with adequate range of motion provided by the arms and without any complications.Trocar placement should be tailored to the site of surgical interest. Robotic-assisted laparoscopy should be considered as a valid alternative to the traditional open approach, when managing solitary masses in recurrent ovarian cancer patients.

Pancreatic cancer is a rare cancer that carries a poor 5 year survival rate of approximately 5% [1]. Approximately 5% to 10% of individuals with pancreatic cancer report having a closely related family member also being diagnosed with pancreatic cancer [2]. Several known genetic syndromes, such as hereditary breast-ovarian cancer syndrome (HBOC) [3], Lynch syndrome [4], familial adenomatous polyposis [5], familial atypical multiple mole melanoma syndrome [6], hereditary pancreatitis [7], Peutz-Jeghers syndrome [8], and Li-Fraumeni syndrome [9] are associated with increased risk of pancreatic cancer.

CONCLUSIONS: Universal tumour testing strategies for guiding germline genetic testing of people with incident CRC for LS in Australia are likely to be cost-effective compared with no testing. Universal germline gene panel testing would not currently be cost-effective. PMID: 31595523 [PubMed - as supplied by publisher]

Screening for Lynch syndrome (LS) is routinely performed in patients with endometrial carcinoma. Currently, no screening recommendations exist for LS in precancerous lesions. The study goal was to determine the incidence of abnormal protein expression in endometrioid intraepithelial neoplasia/atypical hyperplasia (EIN/AH). We analyzed mismatch repair (MMR) protein expression by immunohistochemistry in EIN/AH concurrent with MMR-deficient endometrial carcinomas, and in endometrial biopsy/curettage specimens with EIN/AH from an unselected group of patients. Of 63 patients with MMR-deficient endometrial carcinoma, 34 demonstr...

Endoscopy DOI: 10.1055/a-1016-4977ESGE recommends that individuals with Lynch syndrome should be followed in dedicated units that practice monitoring of compliance and endoscopic performance measures.Strong recommendation, low quality evidence, level of agreement 100 %.ESGE recommends starting colonoscopy surveillance at the age of 25 years for MLH1 and MSH2 mutation carriers and at the age of 35 years for MSH6 and PMS2 mutation carriers.Strong recommendation, moderate quality evidence, level of agreement 100 %. ESGE recommends the routine use of high-definition endoscopy systems in individuals with Lynch syndrome. Str...
