Second-line docetaxel-based chemotherapy after failure of fluorouracil-based first-line treatment for advanced esophageal squamous cell carcinoma.

Abstract

PurposeThis retrospective analysis evaluates the clinical efficacy and toxicity of second-line docetaxel-based chemotherapy after failure of fluorouracil-based first-line treatment for advanced esophageal squamous cell carcinoma (ESCC).MethodsWe retrospectively reviewed patients who had received second-line docetaxel-based chemotherapy for advanced ESCC in Zhejiang Cancer Hospital between January 2008 and December 2011. Survival curves were plotted using the Kaplan–Meier method. The Cox proportional hazard model was used for multivariate analysis.ResultsEighty-five patients received docetaxel-based second-line chemotherapy after the failure of first-line fluorouracil-based treatment. Forty-four patients received docetaxel-platinum chemotherapy, and 41 received docetaxel single-agent treatment. The progression-free survival (PFS) and overall survival (OS) were 3.5 and 5.5 months in all of the patients, respectively. There were no statistically significant differences in PFS and OS between docetaxel-platinum and docetaxel single-agent chemotherapy groups (P-value 0.38 and 0.64, respectively). Response to first-line chemotherapy was a favorable prognostic factor for PFS in uni- and multivariate analyses (P-value 0.005 and 0.028, respectively).ConclusionPatients with docetaxel-based second-line treatment obtained a moderate PFS advantage in advanced ESCC. Response to first-line chemotherapy was a favorable prognostic factor for PFS of second-line chemotherapy in advanced ESCC.
