Background
The objective of this study was to evaluate the efficacy of a gemcitabine and docetaxel (GD) combination as a second-line treatment for patients with metastatic urothelial carcinoma (UC) after failure of first-line treatment with platinum-based chemotherapy.
Methods
From June 2006 to January 2012, 38 patients with metastatic UC previously treated with platinum-based chemotherapy received GD therapy. This consisted of gemcitabine 800 mg/m2 and docetaxel 40 mg/m2 on days 1 and 8 of each 21-day cycle as second-line chemotherapy. All the patients were evaluated for toxicity and assessed every cycle by imaging. We analyzed the efficacy of GD as second-line chemotherapy in the follow-up study.
Results
The median number of GD treatment cycles was 4 (range 2–9); the objective response rate was 47.4 %; and the median progression-free survival and median overall survival were 4.1 and 10.8 months, respectively. Univariate and multivariate analyses on the GD treated group showed that the existence of lung metastases was the only prognostic factor for tumor response. Grade 3 treatment-related toxicity included neutropenia (31.6 %) and thrombocytopenia (15.8 %), and only one patient with grade 4 toxicity had thrombocytopenia (2.6 %).
Conclusions
The GD regimen as second-line chemotherapy was especially effective for lung metastatic UC and yielded favorable results in patients whose first-line platinum-based chemotherapy had failed. Given the safety and benefit profile seen in this study, a large prospective study is warranted to consider the potential utility of GD chemotherapy as a second-line for UC.
