ABSTRACT
We evaluated the efficacy and feasibility of the combination of gemcitabine plus vinorelbine in patients with platinum-based chemotherapy-refractory esophageal cancer. We enrolled 35 patients who received gemcitabine plus vinorelbine as second-line treatment after platinum-based chemotherapy failure between May 2009 and April 2012. Dosage gemcitabine 1,000 mg/m(2) plus vinorelbine 25 mg/m(2); all drugs were administered on days 1 and 8 of a 21-day cycle, and this was continued until failure or unacceptable toxicity. A total of 125 cycles of treatment were administered, and all patients received at least two cycles of treatment (two to five cycles; median number of cycles three). Thirty-two patients were evaluable for response. The response rate was 31.3%, and the disease control rate (partial response plus stable disease) was 62.5%. The progression-free survival (PFS) was 4.3 ± 0.2 months [95% confidence interval (CI), 4.0-4.6], and the median overall survival (OS) was 7.3 ± 0.3 months (95% CI, 6.7-7.8). In the subgroup analysis, median PFS was 4.0 ± 0.2 months (95% CI, 3.6-4.3) in patients with high expression of miRNA-214, while it was 4.6 ± 0.3 months (95% CI, 4.1-5.1) in patients with low expression of miRNA-214 (log rank = 0.023). Myelosuppression with neutropenia and thrombocytopenia was the most common side effect observed with this combination regimen, and higher than grade 3 neutropenia and thrombocytopenia were observed in 10 (31.3%) and 8 patients (25.0%), respectively. Grade 3 fatigue was the most common nonhematologic toxicity, which was observed in 2 (6.1%) patients. The combination of gemcitabine plus vinorelbine was well tolerated as second-line treatment for platinum-based chemotherapy-refractory esophageal cancer patients and appeared to provide enhanced clinical activity especially in patients with low expression of miRNA-214.
