[摘要] 目的 探讨宫颈环形电切术(leep治疗高危型人瘤病毒(HR—hpv感染宫颈上皮内瘤变(CIN)患者应用价值。方法 回顾性分析2009年1月~2010年12月来我院妇科门诊经宫颈TCT诊断为ASCUS及以上的患者资料1 280例,其中对HR—HPV感染、阴道镜下多点活检组织病理学确诊为宫颈上皮内瘤变的患者329例行LEEP治疗,对术前HR—HPV亚型、术后HR—HPV转阴及CIN预后情况进行分析。结果 本组病例中HR—HPV阳性率52.19%,最常见的HR—HPV为16、58、52型。各HR—HPV阳性检出率术后6个月和术后12个月分别下降为32.22%和10.33%,与术前比较差异具有统计学意义(χ2=318.89,P < 0.01)。LEEP手术治疗HR—HPV感染的总有效率达72.34%。结论 LEEP治疗宫颈上皮内瘤变可以有效消除大部分HR—HPV感染,降低宫颈癌发生率。

[Abstract] Objective To discuss the efficacy of the loop electrosurgical excision procedure (LEEP) treatment in cervical intraepithelial neoplasia (CIN) patients with the high—risk type human papilloma virus (HR—HPV) infection. Methods The clinical data of 1 280 cases of gynecologic clinic patients diagnosed with ASCUS by cervical TCT from January 2009 to December 2010 were analyzed retrospectively. Among them, 329 cases of patients with HR—HPV infection and diagnosed with CIN by colposcopic multi—spot biopsy histopathology underwent routine LEEP treatment. The preoperative HR—HPV subtypes, postoperative negative turn and CIN prognosis were analyzed. Results The positive rate in this group was 52.19%, with HR—HPV types 16, 58, 52 being the most common. The HR—HPV positive rate was reduced to 32.22% and 10.33% respectively in 6 and 12 months after operation, showing statistical significance compared with the preoperative data (χ2 =318.89,P < 0.01). The total effective rate of LEEP treatment in HR—HPV infection reached 72.34%. Conclusion LEEP treatment of CIN can effectively eliminate the majority of HR—HPV infection and reduce the incidence of cervical cancer.

宫颈癌是女性生殖系统最常见的恶性肿瘤[1],现有研究已证实高危型人瘤病毒 (HR—HPV)感染是引起女性宫颈上皮内瘤变(CIN)及宫颈癌的重要病因[2]。近年来,宫颈环形电切术(loop electrosurgical excision procedure, LEEP)在CIN诊治中的广泛应用,有效降低了宫颈上皮内瘤发展为宫颈癌的几率。我院对2009年1月~2010年12月在妇科门诊行阴道镜下多点活检组织病理学确诊为宫颈上皮内瘤变、伴HR—HPV病毒感染的患者进行了LEEP治疗,现报道如下。

1 资料与方法

1.1 一般资料

2009年1月~2010年12月来我院妇科门诊就诊时自愿做TCT宫颈疾病筛查的病例中有1 280例被诊断为ASCUS及以上患者,其中经阴道镜下多点活检组织病理学确诊为CIN Ⅰ~Ⅲ级的患者329例,伴HR—HPV感染668例,均在我院行LEEP治疗。该组患者年龄 27~56岁,平均(43.8±21.4)岁,未育有性生活者15例,已生育者267例,绝经者27例。其中CIN Ⅰ级166例(累及腺体15例),CIN Ⅱ、Ⅲ级88例(累及腺体38例)。术后随访时间9~12个月,平均10.5个月。
