Heated Intraperitoneal Chemotherapy

Heated Chemotherapy Offers Advance Abdominal Cancer Patients Longer Life

Until recently, treatment options for patients with advanced abdominal cancers could only provide relief from symptoms, with no hope of stopping the disease from recurring or prolonging life.

Now, with the use of heated intraperitoneal chemotherapy using the FDA-approved ThermoChem(TM) HT-1000 System, surgeons at Saint Barnabas have the potential to dramatically improve the outlook for late-stage patients with colon/rectal cancer, ovarian/uterine cancer, cancer of the small bowel, and pseudomyxoma peritonei syndrome, a rare malignant disorder.

The potent combination of heat, chemotherapy and specialized surgery offers an extended outlook for patients with otherwise untreatable abdominal cancers, most of whom have been given three to six months to live. The specialized system reports response rates of up to 25 percent of patients achieving a greater than two year survival rate.

This new technology allows surgeons to direct a heated sterile solution throughout the entire abdomen, a treatment commonly referred to as Intraperitoneal Hyperthermia (IPH) or Heated Chemotherapy.

What is Heated Chemotherapy?

ThermoChem(TM) is the first and only FDA approved device for IPH. Surgeons use IPH in conjunction with a lengthy 8-10 hour surgery, removing as many tumors as possible from the abdominal cavity. Then, two small incisions are made and tubes are inserted, one to pump the heated chemotherapy into the patient and the other to circulate it back into the machine. The chemotherapy circulates for approximately two hours.

How Does Heated Chemotherapy Work?

Heat kills cancer cells at temperatures where normal cells remain unharmed. Heating the chemotherapeutic agents makes them more effective at killing cancer cells than they would be at normal temperatures. Circulating the heated chemotherapy throughout the peritoneal and abdominal cavity allows the drugs to be distributed thoroughly and penetrate directly, without subjecting you to the side effects of these drugs if given intravenously.

Is Heated Chemo Right for You?

Because such surgery is a major procedure that is not without risk and because the recovery can be substantial, Heated Chemotherapy is not for everyone. To find out if you are a candidate, please contact 973-322-5195 to make an appointment with a surgeon at Saint Barnabas.
