INTRODUCTION: We report the results of a phase II trial exploring the efficacy and the feasibility of combination of gemcitabine and cisplatin concurrent with radiotherapy followed by surgery in patients with stage III non-small cell lung cancer. METHODS: Patients with histocytologically confirmed non-small cell lung cancer were treated with cisplatin 80 mg/sqm/wk of 1 and 4 or 20 mg/sqm/d of weeks 1 and 4 and weekly gemcitabine at 300 to 350 mg/m2 plus involved field radiotherapy. A 3D-conformal radiotherapy was delivered up to 50.4 Gy, with daily fractionation of 1.8 Gy. After clinical, radiologic, and pneumological reassessment, patients who reentered criteria for resectability were operated. RESULTS: The stage at diagnosis was IIIA-N2 in 29 patients and IIIB-T4N0-2 for vascular direct infiltration for the remaining 21. Fifteen patients (30%) experienced acute grade 3 to 4 hematological toxicity, whereas acute grade 3 esophageal toxicity was recorded in three patients (6%). One patient developed a grade 4 pulmonary toxicity (2%). Clinical response was 40 (80%) partial response, one (2%) stable disease, and nine (18%) progressive disease. Thirty-six patients (72%) underwent surgery. Final pathology showed a downstaging to stage 0 to I in 25 cases (50%). Median overall survival for all patients was 21.8 months, with a 3-year survival of 40.2%. CONCLUSIONS: The results of this phase II trial confirm the feasibility and the efficacy of concurrent chemoradiotherapy followed by surgery.
