The primary and secondary objectives are as follows:\n\nPrimary objective: To evaluate the surgical conversion rate in patients with gastric cancer peritoneal metastasis treated with systemic chemotherapy plus immune checkpoint inhibitors combined with HIPEC.\n\nSecondary objectives: To assess the safety, overall survival (OS), progression-free survival, tumor regression rate, incidence of adverse reactions during treatment, postoperative adverse reaction rates, and treatment efficacy of the combination therapy.\n\nParticipants will:\n\nBe willing to receive SOX plus Tislelizumab combined with HIPEC treatment (exposure group), undergo one session of HIPEC followed by SOX plus immune checkpoint inhibitors (two cycles) to achieve stable disease (SD), partial response (PR), or complete response (CR). Patients who can undergo surgery after the second exploration will receive surgery and HIPEC treatment. If surgery is not possible, the next treatment plan will be discussed in a multidisciplinary team (MDT) meeting. Patients with progressive disease (PD) will also have their next treatment plan discussed in an MDT meeting.\n\nBe willing to receive SOX combined with HIPEC treatment (observation group), undergo one session of HIPEC followed by SOX (two cycles) to achieve SD, PR, or CR. Patients who can undergo surgery after the second exploration will receive surgery and HIPEC treatment. If surgery is not possible, the next treatment plan will be discussed in an MDT meeting. Patients with PD will also have their next treatment plan discussed in an MDT meeting.\n\nTreatment details:\n\nSOX: S-1 dosing based on body surface area (BSA): \\\u003C1.25m², 40 mg bid orally, 1.25-\\\u003C1.5m², 50 mg bid orally, ≥1.5m², 60mg bid orally, days 1-14; Q3W; Oxaliplatin 130mg\u002Fm² IV day 1, for a total of 6 cycles.\n\nTislelizumab: 200mg IV, day 1, Q3W, for a total of 6 cycles.
