【摘要】子宫颈锥切术后人乳头瘤病毒(HPV)持续感染是导致高级别鳞状上皮内病变(HSIL)患者病灶残留、复发甚至进展为子宫颈癌的危险因素。子宫颈锥切术后HPV持续感染与病毒、机体、治疗等多方面因素相关,了解其发生的相关因素对提高临床治疗效果、完善术后监测方案、指导女性的生活方式等都将起到重要的作用。该文就HSIL患者子宫颈锥切术后HPV持续感染的病毒因素、机体因素和治疗因素做一综述,以期加深临床医师对相关因素的认识,改善HSIL患者的预后。

【Abstract】Persistent human papillomavirus (HPV) infection after cervical conization is a significant risk factor for residual, recurrence of leision and even cervical cancer in patients with high-grade squamous intraepithelial lesion (HSIL). The persistent infection of HPV after cervical conization is associated with multiple factors, such as virus, organism, and clinical treatment, etc. Understanding the associated factors will play an important role in improving the clinical efficacy, perfecting the postoperative monitoring program and guiding womens lifestyle. In this article, the viral, organism and treatment factors of persistent HPV infection after cervical conization in HSIL patients were reviewed, aiming to deepen the clinicians understanding of related factors and improve clinical prognosis of HSIL patients.

子宮颈鳞状上皮内病变(SIL)是一组与子宫颈浸润癌密切相关的子宫颈疾病。根据2014年WHO最新二分类法,低级别鳞状上皮内病变(LSIL)定义为子宫颈上皮内瘤变1级(CIN1)及p16染色阴性的CIN2,而高级别鳞状上皮内病变(HSIL)则定义为CIN3及p16染色阳性的CIN2[1]。既往研究显示,LSIL大多可自然消退,但HSIL具有潜在癌变风险,应当及时治疗[2-3]。目前临床上多采用子宫颈锥切术对HSIL患者进行治疗,包括子宫颈冷刀锥切术(CKC)和子宫颈环形电切术(LEEP)[4-5]。然而,子宫颈锥切术虽能消除大多数患者的HPV感染,部分患者术后仍可存在HPV持续感染。术后HPV持续感染多被定义为术后至少6个月或连续2次检测到与术前相同类型的HPV感染[6]。多项研究表明,子宫颈锥切术后HPV持续感染是HSIL病灶残留或复发的危险因素[6-9]。基于此背景,笔者拟从病毒、机体、治疗3个方面对HSIL患者子宫颈锥切术后HPV持续感染相关因素的研究现状做一综述,以期提高HSIL患者临床疗效,同时降低子宫颈癌发病率。……
