Standard Infusion Carboplatin Versus Prophylactic Extended Infusion Carboplatin in Patients With Patients With Recurrent, Ovary, Fallopian Tube, and Primary Peritoneal Cancer

Patients who have this kind of cancer are often treated with several drugs. Carboplatin is one that seems to work for many treatment cycles. Even though it may work against the cancer, the patient can become allergic to it. If that happens, they would have to stop taking the drug. The standard way to give carboplatin is by vein over 30 minutes. Some people have been given carboplatin over 3 hours rather than 30 minutes and had fewer allergies than expected. The purpose of this study is to: Find out if giving carboplatin over three hours can prevent the allergy. See if medicine given before the carboplatin can help reduce the risk of allergic reactions.
