摘要 目的通过研究朗格罕细胞组织细胞增生症(LCH)患者中p16基因的表达,了解其基因及功能特点在LCH发病机制中的作用。方法通过免疫组化的方法,检测p16基因在LCH患者病损组织中的表达情况,根据结果将患者分为低表达组及高表达组,比较两组患者临床特点及无事件生存时间。结果 15例累及危险器官患者均为高表达组,多数多系统受累患者为高表达组患者。复发患者中,低表达组与高表达组比较差异无统计学意义。中位随诊时间10个月,低表达组2年无病生存率为(85.7±13.2)%,高表达组为(73.7±11.3)%,虽然呈现出一定变化趋势,但差异无统计学意义。结论 LCH患者病损组织中p16的表达与LCH病情中累及器官的数量、是否累及危险脏器及无病生存时间呈现出一定的关系,预示着病损组织中p16的表达对LCH的病情评估、预后的判断、治疗方案的选择具有重要意义。
