The efficacy and safety of paclitaxel in the treatment of advanced ovarian cancer has been assessed in several phase II trials. McGuire and associates at the Johns Hopkins Oncology Cancer reported results from a phase II trial in which paclitaxel-administered as a 24-hour intravenous (i.v.) infusion with premedication to avoid acute hypersensitivity reactions-yielded one complete response (CR) and 11 partial responses (PRs) (overall response rate, 30%) among 40 previously treated patients with ovarian cancer evaluable for response; 25 of the patients had been refractory to cisplatin therapy. Among 30 evaluable patients who took part in a study at the Albert Einstein Cancer Center, paclitaxel (180 to 250 mg/m2 as a 24-hour i.v. infusion every 21-28 days) produced an overall response rate of 20% (1 CR, 5 PRs). Four responding patients were resistant to previous cisplatin therapy. Median survival for responders was 27 months, and 6 months for nonresponders (P = 0.0001). The Gynecologic Oncology Group confirmed the activity of paclitaxel (175 mg/m2 as a continuous 24-hour i.v. infusion) in 41 evaluable cisplatin-resistant patients, among whom 15 (37%) responded (5 CR, 10 PR). A total of 8 of 27 (29%) patients with cisplatin-refractory disease responded (2/27 CR, 6/27 PR). Among 14 patients whose disease progressed more than 6 months following cisplatin therapy, 3 had CRs and 4 had PRs. Finally, the National Cancer Institute Treatment Referral Center protocol enrolled more than 2,000 patients; preliminary analysis of 1,000 patients included 663 evaluable for response with measurable disease. There are 27 CRs and 119 PRs; median time to progression for responding patients is 7 months.(ABSTRACT TRUNCATED AT 250 WORDS)
