Adequate oral intake~5. Age of 20 years or above~6. Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of 0 or1~7. Adequate hematopoietic which is defined as below,~   * White blood cell count: 3,000/mm3, ≤ 12,000/mm3~  * Platelet count: 100,000/mm3~  * Hemoglobin: 8.0 g/dL~  * ANC: 1500/mm3~8. CA19-9 ≤ 100 U/mL~9. Absence used of chemotherapy or radiotherapy~10. Within 10 weeks following resection of pancreatic cancer~11. Written informed consent given~Exclusion Criteria:~1. Patient previously received adjuvant therapy for pancreatic cancer~2. Patient previously received S-1 treatment and concurrent using other fluoropyrimidine-group anti-cancer drugs, combination therapies with them (such as folinate plus Tegafur-Uracil combination therapy)~3. Recurrence prior to registration~4. Moderate or more severe pleural effusion or ascites upon abdominal CT~5. Inadequate hepatic function which is defined as below:~   * Total bilirubin greater than 1.5 times the ULN~  * Aspartate aminotransferase (AST) or alanine aminotransferase (ALT)greater than 2.5 times the ULN~6. Inadequate renal function which is defined as below:~   Creatinine clearance rate (CCr) \< 60 mL/min~7. Heart failure of Class III (Marked limitation of physical activity. Comfortable at rest, but less than ordinary activity causes fatigue, palpitation, or dyspnea.) or Class IV (Unable to carry on any physical activity without discomfort. Symptoms of heart failure at rest. If any physical activity is undertaken, discomfort increases.) according to the New York Heart Association functional classification~8. Other serious complications such as active peptic ulcer, paresis of intestine or any others~9. Pulmonary fibrosis or interstitial pneumonia clearly observed~10. Uncontrolled watery diarrhea Whether a patient has diarrhea 4 or more times a day while receiving adequate supportive therapy will be used as the indicator to determine whether watery diarrhea is inadequately controlled.~11. Blood transfusion within 2 weeks prior to registration~12. Myocardial infarction within 6 months following documentation of pancreatic cancer~13.

Poorly controlled diabetes mellitus:~    Fasting blood sugar ≥ 200 mg/dL or HbA1c ≥ 10.0 %~15. Participation in the study by the patient is judged difficult due to a complicating psychiatric disorder or psychological symptoms~16. Patient is using drainage.~17. Serious drug allergy or hypersensitivity to the ingredients of S-1~18. Other malignancy with the exception of non-melanoma skin cancer or cervical carcinoma in situ within 5 years prior to registration~19. Pregnant women or nursing mothers, or positive pregnancy test for women of childbearing potential. Fertile women of childbearing potential unless using a reliable and appropriate contraceptive method throughout the treatment period and for three months following cessation of treatment.~20. Man who is willing to conceive a child during the treatment period.~21. On flucytosine, phenytoin or warfarin potassium treatment.~22. Participation in another clinical trial with any investigational drug within 30 days prior to registration.~23.
