Pressurized Intra-Peritoneal Aerosol Chemotherapy (PIPAC) is a laparoscopic procedure of administration of aerosolized chemotherapy within the abdominal cavity, where the laws of physics allow a high tissue concentration of chemotherapy in the cancer cells, but without the usual side effects and toxicity of injected chemotherapy.
Pressurized Intra-Thoracic Aerosol Chemotherapy (PITAC) is the same procedure when used for chest for cancers that have spread to pleura.
