[摘要] 目的 探討宫颈脱落细胞人乳头瘤病毒(HPV)DNA及HPV L1蛋白检测对宫颈病变的预测作用。 方法 选取2013年9月~2015年9月在解放军第一八〇医院就诊的596例宫颈病变患者,根据组织病理学诊断分为:宫颈炎(349例)、宫颈上皮内瘤变Ⅰ级(CINⅠ级,78例)、CINⅡ级(59例)、CINⅢ级(63例)及宫颈癌(47例);根据宫颈液基细胞学检查结果分为:未见异常细胞(NILM,286例)、意义未明的非典型鳞状细胞(ASC-US,81例)、不能排除上皮内病变的非典型鳞状细胞(ASC-H,94例)、轻度鳞状细胞上皮内瘤变(LSIL,79例)及高度鳞状细胞上皮内瘤变(HSIL,56例)。检测不同宫颈病变中的HPV DNA及HPV L1蛋白并进行比较。 结果 HPV DNA阳性者共410例,阳性率为68.8%,以宫颈癌(93.6%)及HSIL(91.1%)最高,宫颈炎(61.3%)及NILM(57.7%)最低,组间总体差异有统计学意义(P < 0.05);HPV L1蛋白阳性者共275例,阳性率为46.1%,以宫颈炎(57.9%)及NILM(60.1%)最高,宫颈癌(12.8%)及HSIL(17.9%)最低,组间总体差异有统计学意义 (P < 0.05)。 结论 宫颈病变程度越高,宫颈脱落细胞HPV DNA阳性率越高,而HPV L1蛋白阳性率越低。二者联合检测对临床诊断宫颈病变及评估风险进展具有重要意义,值得临床推广。

[Abstract] Objective To explore the clinical significance of HPV DNA and HPV L1 protein detection in cervical exfoliated cells. Methods 596 patients with cervical lesions received in the 180th Hospital of PLA from September 2013 and September 2015 were selected. According to histopathological results, patients were divided into cervicitis (349 cases), cervical intraepithelial neoplasia Ⅰ (CINⅠ, 78 cases), CIN Ⅱ (59 cases), CIN Ⅲ (63 cases) and cervical cancer (47 cases). While according to cervical cytology results, patients were divided into normal cells (NILM, 286 cases), unclear of atypical squamous cells (ASC-US, 81 cases), atypical cells suspicious squamous intraepithelial lesions (ASC-H, 94 cases), low-grade squamous intraepithelial lesions (LSIL, 79 cases) and high grade squamous intraepithelial lesions (HSIL, 56 cases). HPV DNA and HPV L1 protein were detected and compared between groups. Results HPV DNA were positive in 410 cases, with the positive rate of 68.8%. The cervical cancer (93.6%) and HSIL (91.1%) had the highest positive rate, while cervicitis (61.3%) and NILM (57.7%) had the lowest positive rate, the overall difference between groups was statistically significant (P < 0.05). HPV L1 protein were positive in 275 cases, with the positive rate of 46.1%. The cervicitis (57.9%) and NILM (60.1%) had the highest positive rate, while cervical cancer group(12.8%) and HSIL group(17.9%) had the lowest positive rate, the overall difference between groups was statistically significant (P < 0.05). Conclusion With the increase of degree of the cervical lesions, the expression of HPV DNA is up-regulated while HPV L1 protein is down-regulated. Combined detection of both targets has important value in diagnosing of cervical lesion and predicting progressive risk. It is worth of clinical promotion.

宫颈癌是常见的女性生殖道恶性肿瘤,在世界范围内居女性恶性肿瘤第2位,在一些发展中国家甚至居于首位。其发病率高,预后差,严重威胁女性身心健康。大样本量的临床流行病学和实验室研究数据已提示人乳头瘤病毒(human papilloma virus,HPV)感染是宫颈癌的主要危险因素,90%以上的宫颈癌患者都有HPV感染[1]。但是,HPV感染并非均导致宫颈恶性病变,大部分的HPV感染即使不经过治疗,8~10个月后也能自行转阴[2]。因此,寻找能够预测宫颈病变结局的方法引起了越来越多的关注。本研究通过联合检测HPV DNA及HPV L1蛋白来评估宫颈病变严重程度,旨在为宫颈病变筛查提供指导。现报道如下:
