[Contribution of intraperitoneal chemotherapy in the treatment of colorectal peritoneal carcinoma. HIPEC, PIPAC, state of the art and future directions]. / La chimiothérapie intra-péritonéale dans le traitement de la carcinose péritonéale d'origine colorectale. CHIP, PIPAC, état des lieux et perspectives.

ABSTRACT

After more than a decade of good results using the combination of cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) in the treatment of peritoneal carcinosis of colorectal origin, the PRODIGE7 study, which specifically evaluated the role of HIPEC, failed to show any superiority in terms of overall and disease-free survival for the CRS+HIPEC combination compared with CRS alone. This study constituted a radical change in the knowledge and therapeutic attitudes observed to date. After reviewing the literature and the consensus of national and international experts, a synthesis is provided, together with an outlook on the questions raised and the therapeutic trials and innovations of the near future. An analysis of recent advances due to the advent of a new technique, PIPAC, is also proposed, as well as a review of current therapeutic trials in this field.
