Paclitaxel (Taxol*) as salvage therapy for relapsed ovarian cancer

Thirty-two patients with epithelial ovarian cancer received paclitaxel 175 mg/m(2), by 3-hour infusion, in this prospective phase 2 study. All patients had relapsed or progressed after initial cisplatin/cyclophosphamide therapy. Thirteen patients received paclitaxel as second line therapy, 14 as third line therapy and 5 as fourth line therapy. One patient was excluded from efficacy analysis, due to a severe anaphylactic reaction to the first cycle of paclitaxel therapy. Of the 31 evaluable patients, complete remission was observed in 3 patients (9.7%) and partial remission in 11 patients (35.5%), with a total response rate of 45.2%. The median survival from diagnosis for the 31 evaluable patients was 32.5 months and the median survival following therapy with paclitaxel was 12.2 months (range 4-27 months). The 3 patients who achieved a complete response remain alive, at greater than 20 months, since commencing paclitaxel. Twelve patients (38.7%) who achieved a partial response, or had stable disease, had a median survival, after paclitaxel treatment, of greater than 18 months. This study confirms the activity of paclitaxel in relapsed ovarian cancer and demonstrates a prolonged survival benefit in greater than one third of this group of patients.
