Phase II trial of weekly docetaxel and gemcitabine as first-line therapy for patients with advanced non-small cell lung cancer

Background A platinum doublet has been the standard treatment for patients with advanced non-small cell lung cancer (NSCLC) and good performance status. This treatment results in almost a doubling of 1-yr survival, along with an improvement in quality of life despite treatment-related toxicities. However, platinum-based treatment may be associated with significant toxicity. Materials and Methods In this trial, we prospectively evaluated a weekly regimen of docetaxel and gemcitabine for advanced NSCLC. The endpoints of this study included objective response rate, survival, and toxicity. Forty-two patients with previously untreated, advanced NSCLC with PS 0-1 were included. Patients received docetaxel (36 mg/m²) and gemcitabine (600 mg/m²) on d 1, 8, and 15 of a 28-d cycle. Responses were assessed every two cycles. The median age was 63 yr; with 22 males and 20 females; 67% were ≥60 years old; and 38 patients had stage IV disease. Results In the intent-to-treat (ITT) analysis of response, 16 patients had a partial response (38%) and 15 patients had stable disease (36%). The 1-yr survival was 48%; median survival for all patients was 11.3 mo and the median progression-free survival was 5.1 mo. Toxicities (≥grade 3) included neutropenia (29%), asthenia (26%), diarrhea (14%), thrombocytopenia (10%), pneumonitis (7%), peripheral neuropathy (5%), peripheral edema (5%), nail changes (2%), and myositis (2%). Conclusions This study demonstrated that this non-platinum doublet (docetaxel+gemcitabine) given on a weekly schedule for advanced NSCLC was well tolerated with efficacy comparable to that reported with platinum-based chemotherapy regimens.
