Paclitaxel in platinum-resistant ovarian cancer patients. Argentine Multicenter Taxol Group.
Paclitaxel (Taxol; Bristol-Myers Squibb Company; Princeton, NJ) is an antineoplastic agent that inhibits microtubular function and has shown efficacy in several solid tumors, mainly ovarian tumors, in which 20% to 40% response rates in previously treated patients were observed. We conducted a study to assess survival, response rate, and toxicity associated with paclitaxel treatment in patients with advanced ovarian cancer resistant to platinum therapy. Between September 1994 and November 1996, 38 patients were admitted for study and 37 were evaluable. All had disease progression or relapse within 1 year of receiving platinum-containing first-line chemotherapy. Mean age was 59 years (range, 30 to 75 years), all had bulky disease, and 18 showed increased carbohydrate antigen-125 at admission. They were treated every 3 weeks with paclitaxel 175 mg/m2 as a 3-hour infusion, preceded by standard premedication. Response rate was 51.3%, with a median response duration of 10.0 months and a median survival rate of 16.8 months. Mild to moderate hematologic toxicity was observed with only one episode of grade 4 neutropenia, without fever. Gastrointestinal toxicity was moderate and peripheral neuropathy was mild, except for two patients who had concomitant pathologies or previous treatment, which might have caused some neuropathy. We concluded that paclitaxel given as a 3-hour infusion was easily administered for ambulatory treatment, with mild to moderate toxicity and promising results based on rate and duration of response as well as survival.
