2、受抗病毒治疗后的组织学改变，及两种评价系统与临床预后的关系。方法连续筛选 2013 年 10 月2014 年 10 月来自 14 个中心的 218 例患者，病理(Ishak评分5 分)诊断肝硬化接受抗病毒治疗 72 周完成 2 次肝组织活检，并符合 P I 分型标准。218 例患者分为无肝细胞癌(HCC)组(n=186)和 HCC 组(n=32)。计数资料组间比较采用 2检验和 Fisher 精确检验。比较抗病毒治疗后 HCC 发生情况时，连续变量采用非参数检验 Mann Whitney U 检验;比较 P I 分型与 Laennec 分级不同组间差异时，连续变量采用非参数检验 Kruskal
3、 Wallis H 检验。采用单因素和多因素 Cox 比例风险回归分析并计算风险比(H)和 95%CI。采用 Kaplan Meier 法计算 HCC 的累积发生率。结果抗病毒治疗 72 周后无 HCC 组和 HCC 组间P I 分型情况比较差异有统计学意义(P 0.001)。抗病毒治疗前后 Laennec 分级和 P I 分型的分布均有统计学差异(P 值均 0 001)。抗病毒治疗后，按照 Laennec 分级分为 4A 组(n=33)、4B 组(n=71)、4C 组(n=114)，3组间 PLT(H=36 429，P 0.001)、LSM(H=13 983，P=0 004)、Ishak 评
4、分(2=23 060，P 0 001)、HAI 评分(P 0.001)比较差异均有统计学意义。抗病毒治疗 72 周后，按照 P I 分型分为 组(n=70)、I 组(n=52)和 P 组(n=96)，3 组间 PLT(H=7.193，P=0 028)、LSM(H=6 238，P=0 045)、Ishak 评分(2=7 986，P 0 001)、HAI 评分(P=0 002)、HCC 发生情况(P 0 001)比较，差异均有统计学意义。P I 分型 P 组和 组 HCC 发生率有显著差异(H=24 21;95%CI:0 46 177 99，P=0 002)。经过调整其他混杂因素后，P I 分型是
5、预测 HCC 发生的独立指标(H=12.69;95%CI:4 63 34 80，P=0 002)。结论P I 分型和 Laennec 分级均能反应患者抗病毒治疗前后纤维化的特征及改变情况，其中 P I 分型对抗病毒治疗后纤维化的改变更敏感。P I 分型(治疗后)可用于预测抗病毒治疗后患者 HCC 发生的风险。关键词:乙型肝炎;肝硬化;癌，肝细胞;P I 分型;Laennec 分级基金项目:国家“十三五”科技重大专项(NCT01965418);北京市自然科学基金(7212101)Association of P I classification and Laennec grading with
