Leuven Dose-Dense Paclitaxel/Carboplatin Regimen in Patients With Primary Advanced or Recurrent Endometrial Carcinoma

Objective: To evaluate the response of dose-dense paclitaxel/carboplatin (TC) patients with primarily advanced or recurrent endometrial cancer. Methods: Six courses of paclitaxel (90 mg/m(2)) and carboplatinum (area under the curve, 4) on days I and 8 every 3 weeks were administered. Response rates were evaluated according to the response evaluation criteria in solid tumors. Results: Dose-dense TC was administered to 42 patients. The median age was 63.9 years (range, 41-81 years). The main histopathologic types were serous/clear cell (n = 27) and endometrioid (n = 13). The patients were divided in 2 groups: chemotherapy-naive group (n = 28, group 1) and a group With previous chemotherapy (n = 14, group 2). The responses for group I were as follows: 11 (39%) complete response, 9 (32%) partial response, and 2 (7%) stable disease. The responses for group 2 were 1 (7%) complete response, 2 (14%) partial response, and 6 (43%) stable disease. Treatment-related death occurred in I patient (7%) because of neutropenia and nephrotoxicity. Progression-free survival for group 1 was 10 months (range, 4-19 months). At time of analysis, 57% of the patients were still alive after a median follow-up Of 10 months (range, 4-21 months). Progression-free survival for group 2 was 11 months (range, 4-19 months). Because of grades 3 and 4 hematologic toxicity, treatment adjustments were as follows: 49 (18%) and 18 (19%) dose reductions (carboplatin area under the Curve, 2-3), 35 (13%) and 14 (15%) dose delays, and 8 (3%) and 6 (6%) treatments were not administered oil day 8 for groups I and 2, respectively. Conclusions: Administration of dose-dense TC resulted in a response rate of 71% in chemotherapy-naive patients. Treatment modifications due to toxicity were frequent, but severe complications such as neutropenic fever Occurred in a similar incidence as other reported 3-weekly regimens.
