CRS and HIPEC are two components of a combined surgical procedure used to treat peritoneal mesothelioma and other abdominal cancers.
Cytoreductive surgery (CRS) involves removing visible tumors and cancerous tissue from the abdominal cavity. Doctors may also remove affected organs or tissues, such as parts of the peritoneum (abdominal lining), organs like the colon or spleen, and any other areas where cancer has spread.
Hyperthermic intraperitoneal chemotherapy (HIPEC) is a technique used during surgery to deliver heated chemotherapy directly into the abdominal cavity to destroy any remaining cancer cells that may not have been visible or accessible during CRS.
