Arms Assigned Interventions
Experimental: 1
S-1, Irinotecan, Bevacizumab
Drug: S-1, Irinotecan, Bevacizumab

S-1 is administered orally on days 1 to 14 of a 28-day cycle. Patients are assigned on the basis of body surface area (BSA) to receive one of the following oral doses twice daily: 40 mg (BSA <1.25m2), 50 mg (BSA >1.25 to <1.50 m2), or 60 mg (BSA >1.50 m2).

Irinotecan 100 mg/m2 is administered by intravenous infusion on days 1 and 15. Bevacizumab 5 mg/kg (body weight)is administered by intravenous infusion on days 1 and 15.

    3. Neutrophil count ≥1,500/mm3
    4. Platelet count ≥100,000/mm3
    5. Total bilirubin ≤1.5 mg/dL
    6. AST and ALT ≤100 U/L (<200 U/L in patients with liver metastasis)
    7. Serum creatinine ≤1.2 mg/dL
    8. Creatinine clearance estimate by the Cockcroft-Gault method >50 mL/min (reduce initial dosage by one step if ≥50 but <80 mL/min)
  8. Able to take capsules orally.
  9. No electrocardiographic abnormalities within 28 days before enrollment that would clinically preclude the execution of the study, as judged by the investigator.
  10. Voluntary written informed consent.

  4. History of gastrointestinal perforation, intestinal tract paralysis, or ileus within 1 year.
  5. Uncontrolled hypertension
  6. Serious complications (e.g., pulmonary fibrosis, interstitial pneumonitis, heart failure, renal failure, hepatic failure, or poorly controlled diabetes)
  7. Moderate or severe ascites or pleural effusion requiring treatment
  8. Watery diarrhea
  9. Treatment with flucytosine or atazanavir sulfate
  10. Metastasis to the CNS
  11. Pregnant women, possibly pregnant women, women wishing to become pregnant, and nursing mothers. Men who are currently attempting to conceive children.
  12. Severe mental disorder
