Concurrent liposomal paclitaxel and cisplatin chemotherapy improved outcomes for locally advanced esophageal squamous cell carcinoma treated with intensity-modulated radiotherapy
Abstract
Background: To ascertain whether concurrent chemotherapy using liposomal paclitaxel and cisplatin could improve the outcomes of patients with locally advanced esophageal squamous cell carcinoma receiving intensity-modulated radiotherapy (IMRT).
Methods: A total of 72 patients with locally advanced esophageal squamous cell carcinoma, which were admitted to our hospital from October 2011 to December 2013, were retrospectively analyzed in this study.
Results: Thirty-six patients (50%) were treated with IMRT alone, while the other 36 patients (50%) were treated by IMRT combined with chemotherapy containing liposomal paclitaxel and cisplatin. Patients treated with chemoradiotherapy showed significantly superior overall survival (OS) and progression-free survival (PFS) compared to patients treated with IMRT alone (median OS: respectively, 29.7 vs. 12.9 months, P=0.0287; median PFS: respectively, 14.0 vs. 6.5 months, P=0.0186). Multivariate Cox analysis confirmed the inclusion of chemotherapy as an independent predictor of favorable OS and PFS. Both chemoradiotherapy and IMRT were well-tolerated in our cohort.
Conclusions: Chemotherapy improved the prognosis of locally advanced esophageal squamous cell carcinoma treated with IMRT. Large prospective studies are needed to confirm the therapeutic value of IMRT combined with chemotherapy in locally advanced esophageal squamous cell carcinoma.
