Complete cytoreductive surgery (CCRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) is a validated treatment in selected patients with peritoneal metastases (PM) of intestinal origin. There is an increased risk of Colorectal Cancer (CRC) and Small Bowel Adenocarcinoma (SBA) in Inflammatory Bowel Disease (IBD). The feasibility and benefit of that surgical approach in IBD patients is unknown. ⋯ CCRS followed by HIPEC is less effective in IBD patients with resectable PM complicating CRC or SBA. More careful selection of those patients is needed.

Primary tumour location has long been debated as a prognostic factor in colorectal cancer patients with liver metastases (CRLM) undergoing liver resection. This retrospective study was conducted to clarify the prognostic value of tumour location after radical hepatectomy for CRLM and its underlying causes. ⋯ The site of the primary tumour has no significant impact on the long-term survival in patients with CRLM undergoing radical surgery. However, prognostic value of RAS status differs depending on the site of the primary tumour.
