About
The study was designed as single-country, multi-center, open-labelled, randomized (1:1), phase II trial.
238 patients with medically and technically operable advanced gastric adenocarcinoma in middle or distal 1/3 of stomach are enrolled and randomly assigned to laparoscopic gastrectomy group and open gastrectomy group. 4 cycles of mFLOT chemotherapy will be conducted before and after gastrectomy.
The primary objective of this study is comparison of D2 lymph node dissection compliance rate between open surgery group and laparoscopic surgery group after neoadjuvant chemotherapy.
Full description
The effect of neoadjuvant chemotherapy on locally advanced gastric cancer was confirmed from a prospective clinical trial. Oncologic safety and excellence of the laparoscopic gastrectomy surgery was recently established for locally advanced gastric cancer.
However, neither technical nor oncologic stability was established for laparoscopic gastrectomy surgery after neoadjuvant chemotherapy. Anticipated benefits from laparoscopic gastrectomy surgery after neoadjuvant chemotherapy are as follows: 1) Reduced postoperative complications; 2) Reduced intra- or postoperative transfusion and patient's pain after surgery; 3) Enhance postoperative recovery (shortened hospitalization duration); 4) Facilitate completion rate of adjuvant chemotherapy.

Methodologies
Patients less than 20 years old or older than 80 years old
Eastern Cooperative Oncology Group(ECOG) ≥ 2
Patients with a surgery experience due to a neoplasm in the stomach.
Patients with complications due to gastric cancer (acute hemorrhage, gastric outlet obstruction or perforation)
Patients with distant metastases (M1) including distant lymph nodes (Retropancreatic, para-aortic, periportal, retroperitoneal, or mesenteric lymph nodes)
Patients without distant metastases but who are, according to a surgeon's judgment, unqualified for radical gastrectomy because of invasions to adjacent organs (T4b).
In the case of localized conglomerated metastatic lymph nodes
Patients who received surgery or radiation therapy for a primary cancer developed in another organ or those with active/synchronous double cancer in recent 5 years.
Patients who participated in another clinical trial or was administered with a different investigational drug in 30 days prior to randomization.
Patients who had any of the following in 6 months before the trial recruitment: myocardial infarction, severe/unstable angina pectoris, coronary/peripheral artery bypass surgery, NYHA class III or IV congestive heart failure, stroke or transient ischemic attack.
Patients with a previous experience of uncontrolled seizure, central nervous system or psychological disorders whose conditions are clinically significant to the extent that they are unable to express consent to participate in the trial and oral drug administration is not possible.
Patients with uncontrolled active infection or sepsis.
Patients who had deep vein thrombosis in recent 4 weeks before the beginning of the trial recruitment.
Patients with serious acute or chronic disease that can degrade the patient's ability to participate in the trial or impede the interpretation of the trial results.
Pregnant or breast-feeding patients. Fertile female patients who are positive in pregnancy test.
