Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Histologically or cytologically confirmed gastric adenocarcinoma with recurrent or metastatic disease
  2. Age ≥18 years
  3. Eastern Cooperative Oncology Group (ECOG) performance status 0-2
  4. Disease status must be that of measurable disease as defined by RECIST criteria:Measurable lesions: Lesions that can be accurately measured in at least one dimension by any of the following: - CT of abdomen, pelvis or thorax, if the longest diameter to be recorded is at least 10 mm with spiral CT- Chest x-ray, if the lung lesion to be recorded is clearly defined and surrounded by aerated lung and the diameter to be recorded is at least 20 mm- Physical examination, if the clinically detected lesions are superficial (e.g., skin nodule and palpable lymph nodes) and at least 10 mm
  5. No prior treatment for recurrent or metastatic disease; prior adjuvant/neoadjuvant therapy is allowed if at least 12 months have elapsed between completion of adjuvant/neoadjuvant therapy and enrolment into the study.

  3. Serious concurrent infection or nonmalignant illness that is uncontrolled or whose control may be jeopardized by complications of study therapy
  4. Other malignancy within the past 3 years except non-melanomatous skin cancer or carcinoma in situ of the cervix
  5. Psychiatric disorder that would preclude compliance
  6. Pregnant, nursing women or patients with reproductive potential without contraception
  7. Patients receiving a concomitant treatment with drugs interacting with S-1 such as flucytosine
