Surgery With HIPEC in Treating Patients With a High Risk of Developing Colorectal Peritoneal Carcinomatosis

Not Applicable

Completed

• Conditions: Peritoneal Carcinomatosis; Malignant Neoplasm of Large Intestine TNM Staging Primary Tumor (T) T4
• Interventions: Procedure: Surgery and Hyperthermic Intraperitoneal Chemotherapy with MMC

• Registration Number: NCT02179489
• Lead Sponsor: Zhejiang University

Brief Summary

Multicentric randomised trial. The goal of this clinical research study is to learn if hyperthermic intraperitoneal chemotherapy (HIPEC) will help to decrease the rate of peritoneal carcinomatosis(PC) in patients with high risk of developing PC of colorectal cancer. The safety of this treatment will also be studied.

Detailed Description

Hyperthermic intraperitoneal chemotherapy(HIPEC) is a recently validated option for the treatment of peritoneal carcinomatosis from colorectal or ovarian origin. This therapeutic program demonstrated a significant improvement of overall survival of the disease. It is not yet known whether surgery followed by HIPEC is effective on decreasing the rate of peritoneal carcinomatosis(PC) in patients with high risk of developing PC of colorectal cancer.Patients with a high risk of developing colorectal Peritoneal Carcinomatosis (PC), defined by Colorectal Cancer With a Resected Minimal Synchronous PC or Ovarian Metastases, or identified T4 by intraoperative pathological diagnosis, or Tumour Rupture in the Abdominal Cavity. If patients with a high risk of developing PC identified by preoperative examination, they will be informed and will sign the consent. After complete resection of their tumor, they will be randomised to surveillance alone (control group) or HIPEC (experimental group). All patients will receive the current standard postoperative adjuvant treatment : 6 months of systemic chemotherapy (currently including FOLFOX4, mFOLFOX6, CapeOx or Capecitabine regimen which could be modified if the standard is modified). Then a work-up is done to find recurrence. If the recurrence occurs, the patient will be treated with the best known treatment.
