JOURNAL OF CLINICAL ONCOLOGY(2018)
Abstract
787Background: Peritoneal carcinomatosis has a dismal prognosis with shorter overall survival than other isolated metastases. In selected patients, HIPEC shows encouraging results. However, early diagnosis continues to be a challenge. COLOPEC trial has been designed to determine the effectiveness of HIPEC in pT4 and perforated colon cancer expecting 25% of peritoneal carcinomatosis in the control arm. A routine second-look procedure in a pilot trial addressed to high-risk patients revealed peritoneal carcinomatosis in 13.3 % in the pT4 group and 50% in the perforation group. Methods: The aim of our study is to describe the risk of clinical/radiological peritoneal relapse in a high-risk population.This is a retrospective study. 711 patients diagnosed with colorectal cancer between 2012 and 2014 according to the hospital – based registry hospital, were reviewed. Patients with stage IV at diagnosis were excluded. 95 cases were considered as high-risk patients. We categorized different classes for pT4 (only),...
