Study Arms:
- Gemcitabine, Ts-1 (Type: EXPERIMENTAL): Gemcitabine : 1000/m2 will be administered on days 1 and 8 at every 3 weeks . TS-1 will be administered orally according to body surface area (BSA) as follows : BSA\<1.25 M2, 80 mg/day; 1.25 M2≤BSA\<1.5 M2, 100 mg/day; 1.5 M2≤BSA, 120 mg/day for 14 consecutive days followed by a 7-day rest.

Based on this trial design, predict the completion outcome and termination type (if applicable).
