Docetaxel+Oxaliplatin+S-1 (DOS) Regimen as Neoadjuvant Chemotherapy in Advanced Gastric Cancer
A Phase III, Open-labelled, Randomised Study of Neoadjuvant Docetaxel+Oxaliplatin+S-1 (DOS) + Surgery + Adjuvant S-1 Versus Surgery + Adjuvant S-1 in Patients With Resectable Advanced Gastric Cancer

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
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.

  • Signed informed consent

Exclusion criteria:

  • Age <20 years or ≥76 years Performance status ≥2 in Eastern Cooperative Oncology Group (ECOG) scale
  • The patients who have the history of other malignancy within the last five years except cured basal cell carcinoma of skin and carcinoma in situ of uterine cervix which have been already successfully treated
  • Previous surgery on neoplasm of stomach
  • Patients who have not completely recovered from surgery
  • Distant metastases (M1) to other organs including distant nodal groups (retropancreatic, para-aortic, portal, retroperitoneal, mesenteric node). severe/unstable angina, coronary artery bypass graft, congestive heart failure, transient ischemic attack within 6 months prior to enrollment in the study
  • Any previous palliative, adjuvant or neoadjuvant chemotherapy and/or radiotherapy and/or immunotherapy, for the currently treated gastric cancer
  • Patients with active active infection or sepsis
  • Intolerance of oral taking or malabsorption: lack of physical integrity of the upper gastrointestinal tract or those who have malabsorption syndrome likely to influence absorption of TS-1.
