Study population: Patients who undergoing laparoscopic radical gastrectomy for gastric cancer are included.

Brief summary: The purpose of this study is to explore the effect of preoperative hemotologic markers on postoperative long-term and short-term outcomes for laparoscopic gastrectomy.

Detailed description: A prospective cohort study will be performed to explore the effect of preoperative hemotologic markers on postoperative long-term and short-term outcomes for laparoscopic gastrectomy.The evaluation parameters are perioperative clinical efficacy, postoperative complications and 3-year survival and recurrence rates.

Eligibility criteria: Inclusion Criteria:

* Age from 18 to 75 years
* Primary lower third gastric adenocarcinoma (papillary, tubular, mucinous, signet ring cell, or poorly differentiated) confirmed pathologically by endoscopic biopsy
* cT2-4a, N0-3, M0 at preoperative evaluation according to the American Joint Committee on Cancer (AJCC) Cancer Staging Manual Seventh Edition
* No distant metastasis is observed. And the spleen, pancreas or other adjacent organs are not involved by the tumor.
* Performance status of 0 or 1 on Eastern Cooperative Oncology Group scale (ECOG)
* American Society of Anesthesiology score (ASA) class I, II, or III
* Written informed consent

Exclusion Criteria:

* Women during pregnancy or breast-feeding
* Severe mental disorder
* History of previous upper abdominal surgery (except laparoscopic cholecystectomy)
* History of previous gastrectomy, endoscopic mucosal resection or endoscopic submucosal dissection
* Enlarged or bulky regional lymph node envelop important vessels
* History of other malignant disease within past five years
* History of previous neoadjuvant chemotherapy or radiotherapy
* History of unstable angina or myocardial infarction within past six months
* History of cerebrovascular accident within past six months
* History of continuous systematic administration of corticosteroids within one month
* Requirement of simultaneous surgery for other disease
* Emergency surgery due to complication (bleeding, obstruction or perforation) caused by gastric cancer
* FEV1\<50% of predicted values
