To analyze the impact of systematic second-look surgery plus hyperthermic intraperitoneal chemotherapy (HIPEC) performed 1 year after resection of the primary tumor in asymptomatic patients at high risk of developing peritoneal carcinomatosis (PC). ⋯ Selection criteria for high-risk patients appear to be accurate. In these patients, the second-look strategy treated peritoneal carcinomatosis preventively or at an early stage, yielding promising results. This study has allowed us to design a multicentric randomized trial (comparing the second-look + HIPEC approach versus standard follow-up alone), which is beginning.
