Multivisceral resection of advanced colon and rectal cancer: a prospective multicenter observational study with propensity score analysis of the morbidity, mortality, and survival

Abstract

In the surgical treatment of colorectal carcinoma (CRC), 1 in 10 patients has a peritumorous adhesion or tumor infiltration in the adjacent tissue or organs. Accordingly, multivisceral resection (MVR) must be performed in these patients. This prospective multicenter observational study aimed to analyze the possible differences between non-multivisceral resection (nMVR) and MVR in terms of early postoperative and long-term oncological treatment outcomes. We also aimed to determine the factors influencing overall survival.
