Summary
Primary Objective:

- To compare progression free survival (PFS) in the two treatment arms

Secondary Objectives:

- Overall survival (OS)

- Postoperative stage and R0 (complete) resection rate

- Safety: Toxicities associated with neoadjuvant chemotherapy, surgery, morbidity/mortality, toxicity of adjuvant chemotherapy1
Detailed Description
Patients in the neoadjuvant chemotherapy arm will be treated for 3 cycles (1 cycle is 21 days) before surgery and treated for a year with TS-1 Patients in the adjuvant chemotherapy arm will get a surgery and treated for a year with TS-1. All patients will be followed during and after the study treatment until death or progression, whichever comes first.
