Peritoneal carcinomatosis significantly worsens the prognosis of patients with gastric cancer. Cytoreduction + hyperthermic intraperitoneal chemotherapy (HIPEC) has shown promising results in the prevention and treatment of peritoneal carcinomatosis in advanced gastric cancer (AGC); however, its application remains controversial owing to the variability of the approaches used to perform it and the lack of high-quality evidence. This systematic review and meta-analysis aimed to investigate the role of surgery and HIPEC in the prevention and treatment of peritoneal carcinomatosis of gastric origin.
We conducted a systematic review and meta-analysis of randomized controlled trials comparing surgery + HIPEC vs surgery + chemotherapy for the prophylaxis of peritoneal carcinomatosis and cytoreduction + HIPEC vs chemotherapy or other palliative options for the treatment of peritoneal carcinomatosis.
Sixteen studies enrolling 1641 patients were included. Surgery + HIPEC significantly improved overall survival in both prophylactic (hazard ratio [HR], 0.56) and therapeutic (HR, 0.57) settings. When surgery + HIPEC was performed with prophylactic intent, the pooled 3-year mortality rate was 32%, whereas for the control group it was 55%. The overall and peritoneal recurrence rates were also reduced (risk ratio [RR], 0.59 and 0.40, respectively). No significant difference was found in morbidity between groups (RR, 0.92).
Based on the current knowledge, HIPEC in AGC seems to be a safe and effective tool for prophylaxis and a promising resource for the treatment of peritoneal carcinomatosis. Regarding the treatment of peritoneal carcinomatosis, the scarcity of large-cohort studies and the heterogeneity of the techniques adopted prevented us from achieving a definitive recommendation.
