- Abstract
Background: Adjuvant oral uracil-tegafur (UFT) has led to significantly longer postoperative survival among patients with non-small-cell lung cancer (NSCLC). Gemcitabine (GEM) monotherapy is also reportedly effective for NSCLC and has minor adverse events (AEs). This study compared the efficacy of GEM- versus UFT-based adjuvant regimens in patients with completely resected pathological stage (p-stage) IB–IIIA NSCLC. Patients and methods: Patients with completely resected p-stage IB–IIIA NSCLC were randomly assigned to GEM or UFT. The primary endpoint was overall survival (OS); secondary endpoints were disease-free survival (DFS), and AEs. Results: We assigned 305 patients to the GEM group and 303 to the UFT group. Baseline factors were balanced between the arms. Of the 608 patients, 293 (48.1%) had p-stage IB disease, 195 (32.0%) had p-stage II disease and 121 (19.9%) had p-stage IIIA disease. AEs were generally mild in both groups, and only one death occurred, in the GEM group. After a median follow-up of 6.8 years, the two groups did not significantly differ in survival: 5 year OS rates were GEM: 70.0%, UFT: 68.8% (hazard ratio 0.948; 95% confidence interval 0.73–1.23; P = 0.69). Conclusion: Although GEM-based adjuvant therapy for patients with completely resected stage IB–IIIA NSCLC was associated with acceptable toxicity, it did not provide longer OS than did UFT.
