Second Line Oxaliplatin Based Chemotherapy Alone Versus Oxaliplatin Based PIPAC and Chemotherapy in Colorectal Peritoneal Carcinomatosis : A Phase II Randomize Mutli-centric Study : OPAC Study

Colorectal cancer is the third most common cancer in men and second in women. It represent 345'346 new cases per year in Europe and 134'349 in the United States of America. The peritoneal cavity is the second most frequent site, after liver, for colorectal cancer relapse.Peritoneal carcinomatosis (PC) is found in approximately 5 % of patients diagnosed with colorectal cancer and 24% of patients with synchronous metastasis at the time of diagnosis. Eight percent of colorectal cancer patient will develop PC during the course of their disease .

Currently systemic chemotherapy is the standard of care for the treatment of unresectable peritoneal carcinomatosis from colorectal cancer with a median survival rate of 16.3 months Peritoneal carcinomatosis has a poor response to systemic chemotherapy due to a weak penetration of agents into the peritoneum.

A new approach of intraperitoneal carcinomatosis is now developed: Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is used to deliver intraperitoneal chemotherapy. It enhances the effect of chemotherapy because of the physical properties of aerosol and pressure.

PIPAC is a safe with a 23% morbidity and tolerated technic that is now well described.

We want to conduct a study to prove or infirm the superiority of PIPAC associated with systemic chemotherapy compare to systemic chemotherapy alone in peritoneal carcinomatosis from colorectal cancer
