Gemcitabine plus cisplatin combination given with amifostine (GAP) to heavily pretreated patients with gynecologic and peritoneal cancers: tolerance and activity in ovarian cancer.

ABSTRACT

Nine patients with cancers of gynecologic or peritoneal origin were treated with a combination of gemcitabine, amifostine and cisplatin (GAP). The rationale of including amifostine was primarily related to the amount of prior cisplatin the patients had received and the need to protect against additional neurotoxicity. After encouraging activity and tolerance had been noted, entry of three patients with severely compromised bone marrow was also allowed. These three patients required dose reductions and did not tolerate treatment more often than every other week, but nevertheless, one of them experienced a partial response lasting 9 months. Another two of the nine patients had CA125 decreases fulfilling Rustin's definition of response and one had elimination of ascites. Future studies of this combination are warranted.
