Background: To evaluate the efficacy and safety of a doublet platinum-free therapy based on Vinorelbine and Gemcitabine in the salvage treatment of patients with advanced NSCLC, previously treated with Carboplatin and Docetaxel. Methods: We conducted a phase II study with the combination of vinorelbine 30 mg/m² and gemcitabine 1000 mg/m² d1 d8 / 3w. Eligible were patients with histologically proven advanced or metastatic NSCLC who were refractory or progressed after first-line chemotherapy combining Docetaxel and Carboplatin. Results of this first-line therapy were already reported (Proc. Am. Soc. Clin. Oncol. 2005, abstr 7330). Patients must have measurable disease, PS 2, life-expectancy 3 months, adequate hematologic, liver and renal functions. Response to therapy was evaluated according to RECIST guidelines. Toxicities were assessed according to the national cancer institute (NCI) common toxicity criteria 3.0. Results: From August 2004 to September 2005, 28 patients were enrolled. Median age was 63 years (range, 44 to 77) with 18 males and 10 females. A total of 109 cycles were delivered with a median of 4 cycles per patient (range, 1 to 9). Mean metastatic sites were lymph nodes in 9 pts, liver in 6 pts and pleura in 5 pts. 26 patients were evaluable for response (1 patient too early and 1 pt lost of follow-up). 6 patients responded partially (23%), one of them was initially resistant to the first-line therapy. 11 patients had stable disease (42%). Mean objective response duration was 7 months (range, 5 to 10+). Main toxicities (grade 3/4) were: anemia in 4 patients, neutropenia in 7 patients, leucopenia in 8 patients and lymphopenia in 4 patients. Neutropenic fever was encountered in only one patient. Non-hematological toxicities grade 3/4 were universally absent. No dose reduction or treatment delay related to toxicity was necessary. Conclusion: The study is still ongoing and more patients are expected to define time to progression and survival. However, these preliminary results were encouraging with low toxicity profile.
