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

Abstract

To evaluate the response of dose-dense paclitaxel/carboplatin (TC) patients with primarily advanced or recurrent endometrial cancer. Six courses of paclitaxel (90 mg/m2) and carboplatinum (area under the curve, 4) on days 1 and 8 every 3 weeks were administered. Response rates were evaluated according to the response evaluation criteria in solid tumors. 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 1 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 1 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 on day 8 for groups 1 and 2, respectively. 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.
