Poor prognosis has been documented among patients with peritoneal spread of gastric cancer, despite chemotherapy being clinically advised as the initial treatment. The prognostic importance of conversion surgery following chemotherapy is still unknown, though. Therefore, the purpose of the current study was to evaluate the clinical effects of conversion surgery in patients with peritoneal spread of gastric cancer. Based on the tumour response to treatment, 93 patients with peritoneal spread of gastric cancer who had chemotherapy between February 2002 and October 2019 were retrospectively enrolled and split into progressing disease (PD) and non-PD groups.
