A Retrospective Comparison of Docetaxel and Paclitaxel for Patients with Advanced or Recurrent Esophageal Cancer Who Previously Received Platinum-Based Chemotherapy

Abstract

Objective: To retrospectively compare docetaxel (DTX) with paclitaxel (PTX) with regard to efficacy and safety in advanced or recurrent esophageal cancer patients who previously received platinum-based chemotherapy. Methods: We retrospectively analyzed 124 advanced or recurrent esophageal cancer patients who had received platinum-based chemotherapy and then received DTX or PTX from April 2006 to November 2010. Results: Eighty-six patients (69.4%) received DTX and 38 patients (30.6%) received PTX monotherapy. Due to toxicity, dose reduction was needed in 36.0 and 27.8% of patients and treatment was discontinued in 10.5 and 2.6% of patients receiving DTX and PTX, respectively. The objective response (25.7 vs. 10.3%, p = 0.03) and disease control rates (60.0 vs. 34.6%, p = 0.01) were higher in the PTX group than in the DTX group, respectively. There were no significant differences in median progression-free survival (2.1 vs. 3.5 months) and overall survival (6.1 vs. 7.2 months) between the DTX and PTX groups, respectively. Grade 3–4 neutropenia (48.8 vs. 21.1%, p = 0.003) and febrile neutropenia (20.9 vs. 5.3%, p = 0.029) were more frequent in the DTX patients than in the PTX patients, respectively. Conclusion: Although the efficacy of DTX and PTX for advanced or recurrent esophageal cancer patients after platinum-based chemotherapy was not significantly different in terms of survival, PTX was a more feasible treatment. PTX provided similar efficacy to DTX with less febrile neutropenia.
