Filter by:This study was conducted to compare the significance of lymph node ratio and absolute count of positive lymph node count on overall survival in patients with rectal cancer who underwent resection with curative intent
Background: laparoscopic resection (LAR) is a safe approach and widely used for rectal cancer after neoadjuvant chemo-radiotherapy, but short term and oncological outcome for converted cases to open surgery (cLAR), may be questioned in an obese patient. Objective: validating the short-term and oncological outcomes after laparoscopic resection and after conversion to open surgery for upper rectal cancer in obese patients. Patients and methods: A prospective study included 191 patients, randomly allocated into two arms of the study, Arm I is open anterior resection (OAR), this is the control and arm II, The LAR. Only 156 analyzed.
Freenome is using a type of artificial intelligence, called machine learning, to identify patterns of cell-free biomarkers in blood to detect cancer early. The purpose of this study is to develop and validate a blood-based assay to detect colorectal cancer by collecting blood and stool samples from healthy patients undergoing routine screening colonoscopy and from patients recently diagnosed with colorectal cancer or advanced adenomas.
The investigators hypothesize that a primary embolization, 3-4 weeks before surgery, would allow development of vascular collaterality, in particular for the marginal artery which will ensure a better colonic perfusion.
