Combination Chemotherapy in Treating Patients With Platinum-Resistant Recurrent Ovarian Cancer

OBJECTIVES:

• Determine the response rate, progression time, and survival of patients with platinum-resistant ovarian cancer treated with weekly paclitaxel and gemcitabine.
• Determine the toxic effects of this regimen in these patients.
• Evaluate the toxic effects and safety profile of premedication with steroids with this regimen in these patients.

OUTLINE: Patients are stratified according to prior treatment with paclitaxel (none or relapse more than 6 months after paclitaxel versus progressive disease or relapse less than 6 months after paclitaxel).

Patients receive dexamethasone IV, then paclitaxel IV followed by gemcitabine IV, for 3 consecutive weeks on days 1, 8, and 15. Treatment is continued every 4 weeks in the absence of disease progression or unacceptable toxicity.

All patients are followed until death.

PROJECTED ACCRUAL: Approximately 18-35 patients will be accrued for this study.
