Effect of HIPEC After Radical Surgery on Long-term Survival for Locally Advanced Gastric Cancer

Within 48 hours postoperative, the first infusion was performed with 3000-4000 ml of saline and 50 mg/m2 cisplatin at 43°C, with an infusion rate of 600 ml/min for a duration of 2 hours. During treatment, close attention is given to the patient's heart rate, blood pressure, oxygenation, and other vital signs. A total of 2 HIPEC treatments were conducted, each 48 hours apart. Systemic chemotherapy is initiated 3-4 weeks postoperative for 6-8 cycles using SOX: intravenous injection of oxaliplatin (130 mg/m2) on the first day and oral administration of tegafur (40-60 mg twice daily, with doses adjusted for body surface area: \<1.25 m2, 40 mg; 1.25m2 ≤ body surface area ≤ 1.5m2, 50mg; body surface area \>1.5m2, 60 mg bid) from day 1 to 14.
