Purpose:
Based on randomized clinical trials, this meta-analysis evaluated the efficacy and safety of intent-to-cure or prophylactic hyperthermic intraperitoneal chemotherapy (HIPEC) for the treatment of gastric cancer.
Methods:
PubMed, Cochrane Library, Medline, and Embase databases were all systemically searched from 2004 to 2023. The quality of the study was assessed by using the Cochrane risk of bias method. The certainty of the evidence was determined by using the GRADE evaluation.
Results:
In this study, 12 articles with a total of 1181 patients were analyzed based on the inclusion criteria. The findings revealed that HIPEC had a higher survival rate (risk ratio [RR] 0.60; 95% confidence interval [CI] [0.43, 0.86], P = 0.005, RR 0.82; 95% CI [0.70, 0.97], P = 0.02, RR 0.83; 95% CI [0.71, 0.96], P < 0.01, and RR 0.63 [0.54, 0.73], P < 0.00001) after 1, 2, 3, and 5 years compared with the control group. The RR was statistically significant for 1, 2, 3, and 5 years. Furthermore, the observed overall recurrence rate for the HIPEC group was lower than control group and statistically significant (RR 0.59; 95% CI [0.50, 0.68], P < 0.0001). Higher disease-free survival rate (RR 1.42; 95% CI [1.07, 1.89], P < 0.01) was observed in the HIPEC group and statistically significant.
Conclusions:
Gastric cancer patients treated with HIPEC have shown promising outcomes with regard to survival, recurrence, disease-free survival, and adverse reactions. However, multicenter trials with larger sample sizes consisting of different ethnicities is suggested.
