This is a Phase II Trial of Perioperative Chemotherapy with Oxaliplatin, 5-Fluorouracil, Leucovorin(MODIFIED FOLFOX6)in Patients with Locally Advanced Operable Gastric Cancer.

The main purpose of this study is to evaluate response rate (clinical response and pathological response) of oxaliplatin, 5-fluorouracil, leucovorin(MODIFIED FOLFOX6)

Inclusion Criteria:

• Previously untreated patients with pathologically proven advanced gastric adenocarcinoma with regional LN metastasis are eligible for this study (clinical stage: cT2-4 and N+). At least one measurable regional lymph node metastasis according to the Response Evaluation Criteria in Solid Tumors (RECIST v. 1.0) [17] is required. Other eligibility criteria include age between 18 and 75 years, Eastern Cooperative Oncology Group performance status (ECOG PS) of 0 or 1, no prior chemotherapy or radiotherapy, and adequate bone marrow, hepatic and renal function (absolute neutrophil count [ANC] ≥ 1.5ⅹ109/L, platelet count ≥ 100ⅹ109/L, total bilirubin ≤ 1.5ⅹupper limit of normal [ULN], serum transaminases ≤ 2.5ⅹULN, alkaline phosphatase ≤ 2.5ⅹULN, serum creatinine ≤ 1.5ⅹULN or actual or calculated creatinine clearance ≥ 50 mL/min).

Exclusion Criteria:

• Exclusion criteria include clinical stage T1 tumors, clinical or radiologic evidence of distant metastasis, intestinal obstruction or impending obstruction, active tumor bleeding, interstitial pneumonitis or symptomatic pulmonary fibrosis, peripheral neuropathy of National Cancer Institute Common Toxicity Criteria (NCI-CTC) grade ≥1, pregnant or breastfeeding patients, and other serious diseases.
