Abstract: Background: Oral adjuvant chemotherapy without hospitalization might reduce the physiological and psychological burden on patients if effectiveness could be guaranteed. We conducted a multicenter feasibility study using S-1, an oral derivative of 5-fluorouracil, as postoperative adjuvant chemotherapy in patients with curatively resected pathologically stage IB-IIIA non-small-cell lung cancer. Patients and Methods: Adjuvant chemotherapy comprised 8 courses (4-week administration, 2-week withdrawal) of S-1 at 80-120 mg per day. Fifty-one patients from 7 institutions were enrolled in this pilot study, from June 2005 to March 2007. The primary end point was the completion rate of scheduled adjuvant chemotherapy. Secondary end points were the incidence and grade of adverse reactions. Results: Fifty patients were eligible. The completion rate for the planned 8 courses of S-1 administration was 72.0% (36 patients). Total percentage administration amount was 71.1%. Grade 3 adverse reactions such as neutropenia (4.0%), anorexia (4.0%), thrombopenia (2.0%), anemia (2.0%), elevated total bilirubin (2.0%), hypokalemia (2.0%), nausea (2.0%), and diarrhea (2.0%) were observed, but no grade 4 adverse effects were encountered. Overall and relapse-free survival rates at 3 years were 87.7% and 69.4%, respectively. Conclusions: Postoperative 1-year administration of S-1 seems feasible as oral adjuvant chemotherapy for lung cancer. The oral formulation and low incidence of adverse reactions permit treatment on an outpatient basis. The present study would be reasonable to follow up with a properly powered phase III trial.
