摘　　要：BACKGROUND Whether patients with diffuse gastric cancer,which is insensitive to chemo-therapy,can benefit from neoadjuvant or adjuvant chemotherapy has long been controversial.AIM To investigate whether perioperative chemotherapy can improve survival of patients with locally advanced diffuse gastric cancer.METHODS A total of 2684 patients with locally advanced diffuse gastric cancer from 18 population-based cancer registries in the United States were analyzed.RESULTS Compared with surgery alone,perioperative chemotherapy improved the prognosis of patients with locally advanced gastric cancer.Before stabilized inverse probability of treatment weighting(IPTW),the median overall survival(OS)times were 40.0 months and 13.0 months(P<0.001),respectively.After IPTW,the median OS times were 33.0 months and 17.0 months(P<0.001),respectively.Neoadjuvant chemotherapy did not improve the prognosis of patients with locally advanced gastric cancer compared with adjuvant chemotherapy after IPTW.After IPTW,the median OS times were 38.0 months in the neoadjuvant chemotherapy group and 42.0 months in the adjuvant chemotherapy group(P=0.472).CONCLUSION Patients with diffuse gastric cancer can benefit from perioperative chemotherapy.There was no significant difference in survival between patients who received neoadjuvant chemotherapy and those who received adjuvant chemotherapy.
