Abstract:
?目的:检测青岛地区居民肺鳞状细胞癌(squamouscellcarcinoma,scc)组织人乳头状瘤病毒(humanpapillomavirus,hpv)感染亚型与肺scc的相关性。方法:收集肺scc石蜡病理切片196例,提取癌组织和癌旁组织dna,应用pcr及斑点杂交技术进行hpv基因检测,并对hpv亚型分布及其与肺scc分级的关系进行分析。结果:在196例标本中,114例(58.16%)存在不同亚型的hpv感染,较癌旁组织14.80%(29/196)明显增高(p<0.05)。主要为hpv6(48/196,24.49%)、hpv16(61/196,31.12%)、hpv18(4/196,2.04%)及hpv58(1/196,0.51%)4型,hpv6阳性主要存在于低度恶性鳞癌中,hpv16阳性主要发生在中高度恶性鳞癌中。吸烟(92.98%)和男性(70.18%)与肺鳞癌hpv感染阳性率正相关(p<0.05),低龄(7.89%)与hpv感染负相关(p<0.05)。结论:hpv感染与肺scc的形成密切相关,低危型hpv6感染在肺鳞癌发生中的作用值得进一步研究。
