Abstract:
Peritoneal metastasis in gastric cancer is associated with rapid disease progression. Hyperthermic intraoperative peritoneal chemotherapy (HIPEC) done immediately after cytoreductive surgery (CRS) has become an important treatment for peritoneal metastasis in gastric cancer patients. However, different treatment options for HIPEC exist with potential influence on survival rates and prognosis in patients, exist. These treatment options include open or closed abdomen technique, perfusion solution, number of catheters, temperature, duration, and drug regimens. This paper aims to provide more evidence on standardization of HIPEC treatment options and technologies by systematically reviewing different drug regimens and technical approaches. The study included 2 randomized controlled trials, 3 phase I/II clinical trials, 2 prospective cohort studies, and 34 retrospective cohort studies, involving 1511 patients. The most common HIPEC option is to dissolve 50-75 mg/m2 of Cisplatin and 30-40 mg/m2 of Mitomycin C in 3-4 L saline solution at 42-43℃. After gastrointestinal anastomosis, 2-3 catheters are used in the HIPEC system with a perfusion flow rate of 500 ml/min. The duration is 60-90 minutes. Anastomotic leakage was low in studies where HIPEC was performed after gastrointestinal anastomosis. The utilization of open HIPEC and a two-drug regimen resulted in improved overall survival rates. The future development of HIPEC aims to enhance tumor-specific therapy by optimizing various aspects, such as identifying the safest and most effective chemotherapy regimens, refining patient selection criteria, and improving perioperative care.
胃癌的腹膜转移与疾病迅速进展相关。细胞减灭术(CRS)后直接进行腹腔热灌注化疗(HIPEC)已成为治疗胃癌腹膜转移患者的重要手段。然而,HIPEC存在不同的治疗方案,如开腹或闭腹、灌注液、管数、温度、持续时间以及不同的药物方案,可影响患者的生存率和预后。本文旨在通过对不同的HIPEC药物技术方案进行系统综述,为HIPEC治疗方案和技术的标准化提供更多参考证据。本文纳入两项随机对照试验、3项Ⅰ和Ⅱ期前瞻性临床试验、两项前瞻性队列研究和34项回顾性队列研究,共1 511例患者。最常见的HIPEC方案为将顺铂50~75 mg/m2和丝裂霉素C 30~40 mg/m2溶解于3~4 L生理盐水中,在42℃~43℃的温度下,胃肠吻合后,于闭腹的HIPEC系统中,使用2~3根导管,灌注液流速为500 ml/min,持续时间为60~90 min。在胃肠吻合后进行HIPEC的研究中,吻合口漏发生率较低。采用开腹HIPEC以及两种药物治疗方案的研究显示总体生存率更高。目前HIPEC的治疗方案存在较大异质性,在临床试验中,需进一步比较技术方法和不同的药物方案,以明确最佳治疗方案,使得该技术合乎标准化。.
