Ages Eligible for Study:   18 Years to 70 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Pathologically proven unresectable adenocarcinoma of stomach
  • With uni-dimensionally measurable disease (at least longest diameter 2 cm on conventional CT scan, x-ray or physical examination, or 1cm on spiral CT scan)
  • Age 18 to 70 years old
  • Estimated life expectancy of more than 3 months
  • ECOG performance status of 2 or lower
  • Adequate bone marrow function(absolute neutrophil count [ANC] ≥1,500/µL, hemoglobin ≥9.0 g/dL,and platelets ≥100,000/µL)
  • Adequate kidney function (serum creatinine < 1.5 mg/dL)
  • Adequate liver function (serum total bilirubin < 2 times the upper normal limit (UNL); serum transaminases levels <3 times [<5 times for patients with liver metastasis] UNL)
  • No prior chemotherapy but prior adjuvant chemotherapy finished at least 6 months before enrollment was allowed. (but, prior adjuvant chemotherapy with capecitabine or S-1 or camptothecin analogues was excluded)
  • No prior radiation therapy for at least 4 weeks before enrollment in the study

Exclusion Criteria:

  • Other tumor type than adenocarcinoma
  • Central nervous system (CNS) metastases or prior radiation for CNS metastases
  • Gastric outlet obstruction or intestinal obstruction
  • Evidence of gastrointestinal bleeding
  • The patient has bony lesions as the sole evaluable disease.
  • Past or concurrent history of neoplasm other than stomach cancer, except for curatively treated non-melanoma skin cancer or in situ carcinoma of the cervix uteri
  • Pregnant or lactating women, women of childbearing potential not employing adequate contraception
  • Other serious illness or medical conditions

    • Unstable cardiac disease despite treatment, myocardial infarction within 6 months prior to study entry
    • History of significant neurologic or psychiatric disorders including dementia or seizures
    • Active uncontrolled infection
    • Other serious underlying medical conditions which could impair the ability of the patient to participate in the study
  • Concomitant administration of any other experimental drug under investigation, or concomitant chemotherapy, hormonal therapy, or immunotherapy
  • concomitant drug medication; The following drugs cause drug interaction with S-1.

    i. Warfarin, phenprocoumon: increase bleeding tendency ii. Increase blood concentration of phenytoin iii. sorivudine: inhibit DPD -> increase toxicity according to fluoropyrimidine iv. allopurinol : decrease activity of S-1
