Current status of chemotherapy for ovarian cancer.
Standard treatment for patients with advanced ovarian cancer has been cytoreductive surgery followed by combination chemotherapy. Until recently, platinum-based chemotherapy was considered optimal and patients were treated with regimens built around either cisplatin or carboplatin. Recently, paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) has been shown to be a highly active agent in refractory ovarian cancer patients. Subsequently, the Gynecologic Oncology Group performed a prospective randomized trial of paclitaxel plus cisplatin compared with cisplatin plus cyclophosphamide in suboptimal stage III and IV ovarian cancer patients. Based on higher response rates, longer time to progression, and marked improvement in median survival (37.5 months compared with 24.4 months), the Gynecologic Oncology Group currently considers paclitaxel plus cisplatin to be the new standard regimen for patients with advanced disease. More recently, paclitaxel plus carboplatin also has been evaluated in previously untreated patients. Using area under the curve dosing for carboplatin, it was demonstrated that this agent could be combined with paclitaxel (175 mg/m2 in a 3-hour infusion) with acceptable toxicity. All current Gynecologic Oncology Group protocols for untreated patients with ovarian cancer use a paclitaxel-based regimen. These clinical trials are evaluating the relative efficacy of carboplatin plus paclitaxel versus cisplatin plus paclitaxel as well as differences in dose and schedule and number of cycles of treatment. Investigational studies are continuing with high-dose chemotherapy that requires hematologic support as well as with intraperitoneal therapy (cisplatin or paclitaxel).
