[Evaluation of paclitaxel and carboplatin in patients with endometrial cancer]

The purpose of this study was to evaluate the combination of paclitaxel and carboplatin in patients with endometrial cancer who have high-risk histopathologic criteria with vessel permeation and low grade, advanced or recurrent disease. The combination of paclitaxel (180 mg/m2 over 3 hours) and carboplatin (dosed at an area under the curve of 5-6) was given intravenously every 3 weeks. Response and toxicity were evaluated according to the Japan Society of Clinical Oncology's response and adverse effect criteria. Eighteen patients were entered in this study and a total of 94 courses were administered. Eleven patients had evaluable lesions. Complete and partial responses were achieved in 5 (45.5%) and 3 (27.3%) patients, respectively. Grade 3 or 4 leukopenia and neutropenia occurred in 49.2% and 90.5% of the patients. G-CSF support was needed in 52.4% of the patients. Only one patient received a platelet transfusion. As a high response rate was obtained, this regimen is considered to be promising treatment for endometrial carcinoma. Prospective comparative study between this combination therapy and the conventional therapy for endometrial carcinoma is warranted.
