影响早期胃癌预后因素的分析

目的]通过对早期胃癌(early gastric cancer,EGC)患者临床资料的研究,探讨EGC淋巴结转移与临床病理特征的关系,找出影响预后因素,以指导临床规范化外科治疗.方法]回顾性分析EGC手术的338例患者的临床资料,分析淋巴结转移与肿瘤大小、组织学类型、浸润深度,大体分型之间的关系;应用Kaplan-Meier法对随访患者资料的预后因素进行生存率分析.结果](1)Dl淋巴结清扫术139例(41.1%),D2淋巴结清扫术183例(54.1%),D3淋巴结清扫术16例(4.7%).淋巴结转移与肿瘤大小、浸润深度有关,差异有显著性意义(P<0.05).(2) 63例随访患者总5年生存率92.1%;黏膜内癌5年生存率97.1%,黏膜下癌5年生存率85.7%;肿瘤大小、浸润深度、淋巴结转移与EGC术后生存率相关(P值分别为0.043、0.004).结论]根据肿瘤大小、浸润深度、淋巴结转移等生物学特点,合理选择手术方案,有助于提高5年生存率,改善预后.

Biologic characters of tumor and gastric cancer prognosis

Objective] By studying the clinical data of 338 patients with early gastric cancer(EGC),who had been performed radical resection upon.The lymph node metastasis rules and distribution were analyzed to find out the relationship between lymph node metastasis and clinical pathological specificity,the prognostic factors for the purpose of improving suvival of EGC patients and quality of life,in order to guide the surgical treatment of clinical standardization.Methods] To review clinical data of the 338 patient...
