Abstract
BACKGROUND
Gastric cancer is the second most common malignant tumor in China, ranking third among all malignant tumor mortality rates. Hyperthermic intraperitoneal chemotherapy (HIPEC) has been shown to increase significantly the effectiveness of intraperitoneal chemotherapeutic drugs, prolong the action time of these drugs on intraperitoneal tumor cells, and enhance their diffusion in tumor tissues. HIPEC may be one of the best choices for the eradication of residual cancer cells in the abdominal cavity.
AIM
The aim of this study was to study the role of preventive HIPEC after radical gastrectomy.
METHODS
A prospective analysis was performed with patients with cT4N0-3M0 gastric cancer to compare the effects of postoperative prophylactic HIPEC plus intravenous chemotherapy with those of routine adjuvant chemotherapy. Patients’ medical records were analyzed, and differences in the peritoneal recurrence rate, disease-free survival time, and total survival time between groups were examined.
RESULTS
The first site of tumor recurrence was the peritoneum in 11 cases in the conventional adjuvant chemotherapy group and in 2 cases in the HIPEC group (P = 0.020). The 1-year and 3-year disease-free survival rates were 91.9% and 60.4%, respectively, in the conventional adjuvant chemotherapy group and 92.1% and 63.0%, respectively, in the HIPEC group. The 1-year and 3-year overall survival rates were 95.2% and 66.3%, respectively, in the conventional adjuvant chemotherapy group and 96.1% and 68.6%, respectively, in the HIPEC group. No significant difference in postoperative or chemotherapy complications was observed between groups.
CONCLUSION
In patients with cT4N0-3M0 gastric cancer, prophylactic HIPEC after radical tumor surgery is beneficial to reduce peritoneal tumor recurrence and prolong survival.
Core tip: This was a prospective analysis performed with patients with cT4N0-3M0 gastric cancer to compare the effects of postoperative prophylactic hyperthermic intraperitoneal chemotherapy plus intravenous chemotherapy with those of routine adjuvant chemotherapy. Prophylactic hyperthermic intraperitoneal chemotherapy after radical tumor surgery is beneficial to reduce peritoneal tumor recurrence and prolong survival.
