Hyperthermic intraperitoneal chemotherapy (HIPEC) has been shown to be an effective treatment for peritoneal tumors; whether preventive HIPEC after radical resection for T4 stage colon adenocarcinoma could decrease peritoneal recurrence remains unknown. The aim of the present study was to compare peritoneal recurrence and short-term survival in patients with T4 stage colon adenocarcinoma undergoing HIPEC plus adjuvant chemotherapy or adjuvant chemotherapy alone following surgery.
