Study Details

Study Description

Brief Summary

SOX regimen, consisting of oral S-1 and intravenous oxaliplatin, is the preferred regimen for perioperative chemotherapy for gastric cancer. The goal of this clinical trial is to compare the efficacy and safety between S-1 combined with oxaliplatin by arterial infusion, as neoadjuvant chemotherapy, and conventional SOX regimen, in locally advanced gastric cancer. The main question it aims to answer is: whether arterially infused oxaliplatin plus S-1 has the potential to be a better neoadjuvant option for patients with locally advanced gastric cancer.

Participants will be randomised, and receive:
  • 3 cycles of conventional SOX chemotherapy or arterial infused oxaliplatin plus S-1, as neoadjuvant chemotherapy;

  • Adequate gastric resection along with D2 lymph node dissection;

  • 5 cycles adjuvant chemotherapy using SOX regimen.

Researchers will compare the 2-year overall survival (OS) rates, 2-year disease free survival (DFS), R0 resection rates, and adverse events, to see if the modified perioperative chemotherapy improve the prognosis of patients with locally advanced gastric cancer.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Arterial infusion group

3 cycles of neoadjuvant chemotherapy: Oxaliplatin arterial infusion+S-1 surgery and 5 cycles of adjuvant chemotherapy using SOX regimen

Drug: Oxaliplatin by arterial infusion plus S-1
3 cycles oxaliplatin by arterial infusion plus S-1 every 21 days as neoadjuvant chemotherapy.

Procedure: gastrectomy plus D2 lymph node dissection
All patients, whose lesions are resectable and medically operable after 3 cycles neoadjuvant chemotherapy, will receive gastrectomy plus D2 lymph node dissection.

Drug: SOX adjuvant, Sequential S-1
5 cycles of SOX adjuvant chemotherapy every 21 days after surgery in both groups. Sequential S-1 chemotherapy every 21 days till 1 year postoperation.

Active Comparator: SOX group

3 cycles of neoadjuvant chemotherapy: SOX regimen surgery and 5 cycles of adjuvant chemotherapy using SOX regimen

Drug: SOX neoadjuvant
3 cycles of SOX neoadjuvant chemotherapy every 21 days.

Procedure: gastrectomy plus D2 lymph node dissection
All patients, whose lesions are resectable and medically operable after 3 cycles neoadjuvant chemotherapy, will receive gastrectomy plus D2 lymph node dissection.

Drug: SOX adjuvant, Sequential S-1
5 cycles of SOX adjuvant chemotherapy every 21 days after surgery in both groups. Sequential S-1 chemotherapy every 21 days till 1 year postoperation.

Outcome Measures

Primary Outcome Measures
