repeatA Randomized Single Center Controlled Study of Perioperative Chemotherapy of Oxaliplatin Combined With Capecitabine (XELOX) Versus XELOX as Post-operative Chemotherapy in Advanced Gastric Adenocarcinoma With D2 Dissection

Study start date: September 1, 2013

Inclusion Criteria: * Karnofsky performance status of ≥60 %. * Histologically confirmed gastric adenocarcinoma, staged pathologically or clinically, stage cT2-4N+M0, and cT4N0M0. * Patients had to have adequate renal function (serum creatinine ≤1 times the upper limit of normal \[ULN\]), hepatic function (total bilirubin ≤1·5 times the ULN, aspartate or alanine aminotransferase ≤2·5 times the ULN, alkaline phosphatase ≤2·5 times the ULN, Serum albumin ≥30g/L), and haematological function (absolute neutrophil count ≥1·5×10⁹/L and platelet count ≥100×10⁹/L) Exclusion Criteria: * Pregnant or lactating women. * According to the AJCC TMN 7.0, Any evidence of metastatic (TxNxM1) patients(including presence of tumor cells in the ascites). * Sexually active males and females (of childbearing potential) unwilling to practice contraception during the study. * Previous cytotoxic chemotherapy, radiotherapy or immunotherapy except corticosteroids, for the currently treated gastric cancer. * Has uncontrolled epilepsy, central nervous system diseases or mental disorders of history. * Clinically significant (i.e. active) cardiac disease e.g. symptomatic coronary artery disease, New York Heart Association (NYHA) grade II or greater congestive heart failure or serious cardiac arrhythmia requiring medication or myocardial infarction within the last 12 months. * Lack of physical integrity of the upper gastrointestinal tract or those who have malabsorption syndrome likely to influence absorption of capecitabine, or inability to take oral medication. * Known peripheral neuropathy ≥ CTCAEv3 grade 1 (Common Terminology for Adverse Events). Absence of deep tendon reflexes as the sole neurologic abnormality does not render the patient ineligible. * Organ allografts requiring immunosuppressive therapy. * Serious uncontrolled intercurrent infections or other serious uncontrolled concomitant disease. * Moderate or severe renal impairment \[creatinine clearance equal to or below 50 ml/min (calculated according to Cockroft and Gault)\], or serum creatinine \> 1.5 x upper limit of normal (ULN). * Any of the following laboratory values: * Absolute neutrophil count (ANC) \< 1.5 x 109/L * Platelet count \< 100 x 109/L * Total bilirubin \> 1.5 x ULN * ALAT, ASAT \> 2.5 x ULN * Alkaline phosphatase \> 2.5 x ULN. * Prior unanticipated severe reaction to fluoropyrimidine therapy (with or without documented dihydropyrimidine dehydrogenase (DPD) deficiency) or patients with known DPD deficiency. * Hypersensitivity to platinum compounds or any of the components of the study medications. * Received any investigational drug or agent/procedure, i.e. participation in another trial, within 4 weeks before randomization.
