title: Activity of paclitaxel as second-line chemotherapy in endometrial carcinoma: a Gynecologic Oncology Group study.
abstract: OBJECTIVE
  To estimate the antitumor activity of paclitaxel (Taxol) in patients with persistent or recurrent endometrial carcinoma who have failed prior chemotherapy. To determine the nature and degree of toxicity of paclitaxel in this group of patients.
  
  
  METHODS
  Paclitaxel was administered as a 3-h infusion at an initial dose of 200 mg/m(2) every 21 days or 175 mg/m(2) for patients with prior pelvic radiation therapy. Dose modifications were based on nadir toxicity, both hematologic and nonhematologic, and were accomplished by dose level adjustments. The dose levels were 200, 175, 135, and 110 mg/m(2). Patients were evaluable for response after receiving one dose of paclitaxel and living 3 weeks. They were evaluable for toxicity after receiving any paclitaxel.
  
  
  RESULTS
  Of the 44 patients evaluable for response, three patients (6.8%) achieved a complete response and nine patients (20.5%) had a partial response for an overall response rate of 27.3%. The 95% confidence interval for the true response rate was 15-42.8%. The median number of courses of paclitaxel to response was 2 (range: 1-4) and the median response duration was 4.2 months. The median overall survival was 10.3 months. Of 48 patients evaluable for toxicity, 28 experienced at least one episode of grade 3 or 4 neutropenia, with one treatment-related death. There were four patients who developed grade 3 neurotoxicity in this group of previously treated patients, most of whom had received cisplatin-containing chemotherapy. There was virtually no cardiac toxicity and only 3 of 48 patients experienced grade 3 or 4 gastrointestinal symptoms.
  
  
  CONCLUSIONS
  Paclitaxel is an active agent in the treatment of endometrial cancer in patients who have had prior chemotherapy.
