The investigators confirm the feasibility of 1-year administration of oral fluoropyrimidine S-1 as an adjuvant chemotherapy for the patient who received complete resection of non-small cell lung cancer. The investigators presume they can achieve high completion rate with low toxicity.

Estimated Enrollment: 55
Study Start Date: June 2005
Study Completion Date: March 2012
Primary Completion Date: May 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: S-1
Single arm of the patients who received complete resection of pathological stage IB, II, or IIIA Non-small cell lung cancer
Drug: S-1
Chemotherapy comprised eight courses (4-week administration, 2-week withdrawal; total 1 year) of S-1 at 80-120 mg/body/day according to body surface area (BSA)
Other Name: Oral fluoropyrimidine S-1

Detailed Description:
Chemotherapy comprised eight courses (4-week administration, 2-week withdrawal) of S-1 (FT, gineracil, oteracil potassium; Taiho Pharmaceutical, Tokyo, Japan) at 80-120 mg/body/day according to body surface area (BSA): BSA <1.25 m2, 80 mg/day; BSA >1.25 m2 but <1.5 m2, 100 mg/day; and BSA >1.5 m2, 120 mg/day. S-1 was administered orally, twice daily after meals, starting within 4 weeks after surgery.
