Background: The goals of the current study were to determine the safety and efficacy of a nonplatinum-containing doublet, gemcitabine and docetaxel, in the treatment of patients with chemotherapy-naive nonsmall cell lung carcinoma (NSCLC).
Methods: Thirty-two patients with advanced, chemotherapy-naive NSCLC were treated with gemcitabine (1000 mg/m(2)) and docetaxel (40 mg/m(2)) administered on Days 1 and 8 every 21 days. All patients were evaluable for toxicity and survival and 27 patients were evaluable for response.
Results: This combination was extremely well tolerated with Grade 3 or 4 neutropenia occurring in 6 of 32 patients (19%) (grading was based on the National Cancer Institute Common Toxicity Criteria). There were two episodes of Grade 3 thrombocytopenia and no episodes of Grade 3 or 4 anemia. Grade 3 or 4 nonhematologic toxicities included nausea (occurring in 1 of 32 patients), diarrhea (occurring in 1 of 32 patients), fatigue (occurring in 10 of 32 patients), fluid retention (occurring in 2 of 32 patients), anorexia (occurring in 4 of 32 patients), and transaminitis (occurring in 2 of 32 patients). Six patients experienced Grade 3 pneumonitis that was at least possibly related to the combination of gemcitabine and docetaxel. There was 1 complete response and 7 partial responses for an overall response rate of 30%. The 1-year and median survivals were 35% and 7.9 months, respectively.
Conclusions: In the current study, the regimen of gemcitabine (1000 mg/m(2)) and docetaxel (40 mg/m(2)) administered on Days 1 and 8 every 21 days was well tolerated with manageable hematologic and nonhematologic toxicities. The responses were comparable to those achieved with platinum-based combination chemotherapy and the 2-year survival was an encouraging 19%. These data would support the further study of this nonplatinum doublet in patients with advanced NSCLC.
