摘要
目的:检测人乳头状瘤病毒(HPV)16-E6蛋白在外阴上皮内非瘤样病变(NNEDV)、外阴鳞癌(VSCC)中的表达,探讨HPV16-E6蛋白是否为NNEDV病因及与VSCC的相关性。方法:采用免疫组织化学SP法检测HPV16-E6在15例正常外阴组织,40例NNEDV及45例VSCC中的蛋白表达情况。结果:HPV16-E6蛋白在正常外阴皮肤组无表达,在NNEDV及VSCC中阳性表达率分别为30%和66.67%,差异均有统计学意义(P<0.05)。在NNEDV组中,HPV16-E6蛋白在鳞状上皮增生(SH)型及硬化性苔藓(LS)型阳性率分别为35%和25%,差异无统计学意义(P>0.05),但均较正常外阴皮肤组升高(P<0.05),较VSCC组降低(P<0.05)。HPV16-E6在VSCC的表达阳性率为66.67%,阳性率随临床分期的增高而增高,I期和II期,I期和III期比较差异均有统计学意义(P<0.017),但II期和III期比较差异无统计学意义(P>0.017)。随着肿瘤分化程度的增高,阳性率逐渐降低,高分化和低分化,中分化和低分化比较差异均有统计学意义(P<0.017),但高分化和中分化比较差异无统计学意义(P>0.017)。有淋巴结转移者HPV16-E6阳性表达率高于无淋巴结转移者(P<0.05)。结论:HPV感染可能是NNEDV的病因之一。HPV16-E6蛋白表达升高可能与VSCC发生、发展相关。
Objective: To investigate the expression of high risk human papilloma virus (HPV) 16-E6 protein in non-neoplastic epithelial disorders of the vulva (NNEDV) and squamous cell carcinoma of the vulva (VSCC), and to explore whether HPV16-E6 protein is the etiological factor in NNEDV and its correlation with squamous cell carcinoma of the vulvae.Methods: We detected HPV16-E6 protein expression in 15 normal vulvae cases, 40 NNEDV cases and 45 VSCC cases by immunohistochemistry SP method. Results: The positive rate of HPVI6-E6 in different vulva tissues: was 0% in the normal vulva, 30% in NNEDV and 66.67% in VSCC, respectively. The overall positive rate and two two comparison had statistical significance. In the NNEDV group, the positive rate of squamous hyperplasia type and lichen sderosus type was 35% and 25%, respectively, with no statistical significance (P〉0.05), but higher than that in the normal vulva skin group (P〈0.05) and lower than that in the VSCC group (P〈0.05). The positive rate of HPV16-E6 in VSCC was 66. 67%. The positive rate increased with the clinical stage. The positive rate between Phase Ⅰ and PhaseⅡ, and that between Phase Ⅰ and Phase Ⅲ had statistical significance (P〈0.017), but that between Phase Ⅱ and Phase Ⅲ had no statistical significance (P〉0.017). The positive rate gradually decreased with the tumor differentiation. The difference in well-differentiated and poorly differentiated, moderately and poorly differentiated had statistical significance (P〈0.017), but that of well-differentiated and moderately differentiated had no statistical significance (P〉0.017). The positive rate of lymph node metastasis VSCC was significantly higher than that of non-lymph node metastasis VSCC (P〈0.05). Conclusion: HPV infection may be an etiological factor for NNEDV. The rise of HPV16-E6 positive rate may be related to the occurrence and development of vulvar squamous cell carcinoma.
