  • Hyperthermia (High temperature) has several benefits in the treatment of cancer. Heat increases the penetration of chemotherapy drugs into tissues, heat increases the efficacy of some chemotherapy drugs. Heat has by itself an anti-tumor effect.

  • Hyperthermic Intraperitoneal Chemotherapy (HIPEC) refers to the intraoperative administration of heated chemotherapy into the peritoneal cavity, after all tumor tissue has been resected (Cytoreductive Surgery). This technique permits the administration of high concentrations of chemotherapy into the abdomen and pelvis.

  • Peritoneal Carcinomatosis refers to the spread of cancer in the abdominal cavity. Tumor deposits, metastasis, fluid, or mucin (gelatinous material) are found on the abdominal and pelvic surfaces and organs.

  • Peritoneal perfusion refers to the delivery of heated chemotherapy (see HIPEC) into the peritoneal cavity using a special device with computerized control over flow, pressure and temperature.

  • Peritoneal Cancer Index (PCI) refers to the method used to measure spread of cancer in the peritoneal cavity.
