文摘目的:腹膜假黏液瘤(pseudomyxoma peritonei,PMP)是一种罕见的临床综合征,细胞减灭术(cytoreductive surgery,CRS)联合腹腔热灌注化疗(hyperthermic intraperitoneal chemotherapy,HIPEC)因其良好的治疗效果已经成为各中心公认的标准治疗方案,航天中心医院从2008年开始致力于PMP患者诊治工作,2016年开始将全腹膜切除应用于临床,本研究通过对既往资料进行收集整理,对PMP治疗经验进行总结。方法:回顾分析2008年1月到2019年1月航天中心医院腹膜假黏液瘤中心收治并接受手术治疗的PMP患者临床资料及随访结果。对所有患者的手术方式、根治程度及并发症发生情况等临床资料进行搜集整理,并通过随访结果对相关因素进行生存分析,了解CRS+HIPEC在PMP治疗中的临床价值,同时对腹膜切除技术治疗效果进行评价。结果:共纳入854例患者,平均年龄50岁,中位改良腹膜肿瘤指数(peritoneal cancer index,PCI)为29,其中25.5%的患者接受了根治性手术切除,细胞减灭程度(completeness of cytoreduction,CC)达到0或1。总体并发症发生率为21.7%,围术期死亡率为1.1%。自2016年引进腹膜切除技术后,本中心达CC-0/1的比例由14.3%升至36.5%,且并发症发生率显著下降(16.8%vs.28.8%,P<0.001)。总体而言,CC-0/1的患者5年和10年生存率分别为77%、64.3%,显著优于CC-2/3患者的45.8%、39.4%。在未达根治的患者中,CC-2和CC-3患者10年生存率也存在明显差异(45.5%vs.34.5%,P=0.006)。对总体生存进行分析,改良腹膜肿瘤指数、手术方式、术中是否行热灌注治疗、病理级别、CA125水平均为影响术后生存的独立危险因素。结论:细胞减灭术+腹腔热灌注化疗治疗腹膜假黏液瘤安全有效,腹膜切除技术可显著提高根治程度并降低并发症风险;对于无法达到根治切除的患者,最大限度的减瘤亦可延长远期生存。
