Abstract： 目的探讨胰腺导管腺癌、慢性胰腺炎和正常胰腺组织中各级别PanIN的发生率以及与临床病理学参数间的关系.方法回顾性研究长海医院2001年1月～ 2003年12月间外科切除和同期尸检获得的250例胰腺标本中PanIN的发生情况,并联系临床病理指标进行相关分析.结果 250例胰腺标本中,有156例存在PanIN病变,发生率62.4%.其中,胰腺导管腺癌、慢性胰腺炎和正常胰腺组织中PanIN的发生率分别为75.6%、46.0%和30.0%,胰腺导管腺癌PanIN发生率明显高于慢性胰腺炎及正常胰腺组织(P < 0.01);慢性胰腺炎中高级别PanIN发生率明显高于正常胰腺组织(P < 0.05).PanIN-3仅在胰腺导管腺癌和慢性胰腺炎中见到.胰腺导管腺癌中,有烟酒嗜好和(或)糖尿病者高级别PanIN的发生率53.7%,明显高于对照组29.4%(P < 0.01).PanIN的发生率以61 ～ 70岁年龄组为最高.结论胰腺导管腺癌、慢性胰腺炎和正常胰腺组织中PanIN的发生率逐渐增加,程度逐渐加重,支持胰腺癌发生的分子模型.
