Treatment with paclitaxel plus carboplatin, alone or with irradiation, of advanced or recurrent endometrial carcinoma

ObjectivesThe goal of this study was to evaluate the efficacy and toxicity of paclitaxel plus carboplatin in the treatment of primarily advanced or recurrent endometrial carcinoma.MethodsThirty-seven consecutive patients with advanced or recurrent endometrial carcinoma were enrolled in this study. Paclitaxel at a dose of 175 mg/m2 was administered intravenously over 3 h followed by carboplatin with area under the curve of 5 to 6 over 1 h at 4-week intervals. Five patients were received 50 Gy pelvic irradiation, and 7 were received 50 Gy pelvic and 50 Gy paraaortic irradiation, after adjuvant chemotherapy with paclitaxel plus carboplatin. Eighteen patients had evaluable lesions. Responses were assessed before the use of any irradiation.ResultsEleven patients (61%) achieved an objective response, including one complete response (5.6%) and 10 partial responses (56%). The most common toxicity was hematologic: grade 3 or 4 leukopenia and neutropenia occurred in 59% and 86% of patients, respectively. Three patients (8%) required granulocyte colony-stimulating factor support. One patient required a platelet transfusion, and four required blood transfusions. There was a single adverse event of anaphylaxis.ConclusionThe combination of paclitaxel and carboplatin appears to be an effective regimen for the treatment of patients with advanced or recurrent endometrial carcinoma with tolerable toxicity.
