    Abstract:
    BACKGROUND: The benefits of adjuvant chemotherapy for completely resected non-small cell lung cancer (NSCLC) have been demonstrated using mainly cisplatin (CDDP)-based chemotherapeutic regimens. However, treatment-related deaths sometimes occur. Therefore, the development of a safer regimen is necessary. PATIENTS AND METHODS: The patients were randomized to either carboplatin (CBDCA) area under the curve (AUC) 3 and paclitaxel (PTX) 90 mg/m(2) (PCb arm) or CBDCA (AUC3) plus gemcitabine (GEM) (1000 mg/m(2)) (GCb arm) every 2 weeks for 8 cycles after surgery. The primary endpoint was the compliance with the regimen, while the secondary endpoints were safety and toxicity. RESULTS: A total of 75 patients were enrolled in a multi-institutional study. Twenty-one out of 39 patients (54%) in the PCb arm and 25 of 36 patients (69%) in the GCb arm completed 8 cycles, and 59% in the PCb arm and 81% in the GCb arm completed ≥6 cycles. The predominant toxicity was neutropenia. Non-hematological adverse effects were infrequent and no treatment-related death was registered. The estimated disease-free survival and overall survival at 2 years were 70.8% and 66.3% in the PCb and 91.4% and 79.1% in the GCb arm, respectively. CONCLUSION: This adjuvant bi-weekly scheduled chemotherapy resulted in good compliance in both arms, and the regimen was feasible, with acceptable levels of toxicity in completely resected Japanese NSCLC patients. Therefore, these regimens represent a new treatment option suitable for outpatients with completely resected NSCLC.
