Hyperthermic intraperitoneal chemotherapy (HIPEC) for appendix cancer one potential option for advanced-stage appendix cancer.

Before patients receive HIPEC treatment, doctors perform cytoreductive surgery to remove visible tumors within the abdomen. Cytoreductive surgery is accomplished using various surgical techniques. Once as many tumors as possible have been removed, the heated, sterilized chemotherapy solution is delivered to the abdomen to penetrate and destroy remaining cancer cells. The solution is 41 to 42 degrees Celsius, about the temperature of a warm bath. It’s circulated throughout the abdomen for approximately 1 ½ hours. The solution is then drained from the abdomen and the incision is closed.

HIPEC is a treatment option for people who have advanced surface spread of cancer within the abdomen, without disease involvement outside of the abdomen.
