 Hypothermic intraperitoneal chemotherapy for ovarian cancer is performed to treat advanced cancers that have spread in the peritoneal cavity. Pre-surgery, you may undergo some blood tests, CAT and MRI scans. The doctor may ask you to stop certain medications a few days before the surgery. On the day of the procedure, post-administering general anesthesia, the surgeon removes all visible tumors from the abdomen. A heated chemotherapy drug is then pumped through the abdominal cavity. Surgeon distributes the chemotherapy fluid equally for 90 minutes to ensure direct contact of the fluid with all the remaining cancer cells. The tumor removal portion of the operation typically takes anywhere between 2-4 hours to as many as 8-9 hours depending on the number of tumors that need to be removed. The chemotherapy application takes another 2 hours. Most patients are discharged from the hospital within 10-12 days and you may be asked to complete follow-up visits after the surgery.
