摘要 [目的]探讨荧光原位杂交(FISH)技术在检测p53基因缺失中的应用,并评估其应用于肺腺癌诊断的可行性及临床应用前景。[方法]采用FISH技术在基因水平上检测30例肺腺癌及20例良性病变的p53基因缺失情况,比较两组间有无统计学差异,同时建立阳性检测的阈值,比较两组间p53基因缺失的阳性率。采用免疫组化检测30例肺腺癌p53蛋白表达情况,并分析肺腺癌p53基因缺失和p53蛋白阳性表达之间有无统计学意义。[结果]30例肺腺癌p53基因缺失率为(38.3%±8.9%),20例良性病变对照组为(13.3%±2.4%),两组间有显著统计学差异(P<0.01)。p53蛋白阳性组与阴性组间的p53基因缺失率无统计学意义(P>0.05)。[结论]p53基因缺失的高表达在肺腺癌的发生中可能起重要作用,用FISH技术检测p53基因缺失率可能对肺腺癌诊断和治疗提供更加准确的依据。
