Propuesta de enfoque diagnóstico y terapéutico de la carcinomatosis peritoneal originada en el colon

Introduction. Colorectal cancer is the fourth leading cause of cancer worldwide, with an incidence of 17.2 per 100,000 population, and in Colombia the incidence is 10.6 per 100,000, associated with high mortality. Metastatic cancer to the peritoneum is considered a systemic condition, for which only palliative chemotherapy is offered due to the poor prognosis. Cytoreductive surgery plus intraperitoneal hyperthermic chemotherapy is great option for these patients, optimizing their condition and overall survival. Objective. The aim of this article is to propose a flowchart for the selection of patients with colorectal carcinomatosis using the severity score scale of surface peritioneal disease for the proper administration of intraperitoneal hyperthermic chemotherapy. Material and methods. We completed a systematic search for articles in the PubMed, EMBASE and COCHRANE data bases with the MESH terms "colorectal cancer", "peritoneal metastases" and "peritoneal carcinomatosis", encountering four articles based on the use of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy that assessed the patients characteristics, the treatment received, and the follow-up. Results and discussion. We propose a flow diagram based on the clinical, imaging and histological characteristics, that allows classifying the severity of the disease, and therefore define those that can benefit from systemic chemotherapy versus hyperthermic intraperitoneal chemotherapy, and thus reduce complications rates and optimize management.
