宫颈细胞学ASCUS/LSIL的临床意义及处理

目的探讨宫颈不典型鳞状上皮，低度鳞状上皮内病变（ASCUS／LSIL）的临床意义及处理方法。方法对中国医学科学院肿瘤医院2004～2006年妇科门诊用TCT（宫颈液基细胞学）的方法检出的254例ASCUS／LSIL以病理结果为金标准进行回顾性分析，其中136例进行了阴道镜检查。结果在140例ASCUS中，宫颈上皮内瘤变（CIN）病变占51．5％，其中高度病变占22．9％，114例LSIL中CIN病变占59．6％，其中高度病变占30．7％，两组资料比较差异无统计学意义，P〉0．05。其中136例中阴道镜诊断炎症47例，低度宫颈上皮内病变53例，高度宫颈上皮内病变36例及病理检查结果炎症55例，低度宫颈上皮内病变41例，高度宫颈上皮内病变40例，阴道镜与病理对照进行了～致性检验，Kappa=0．314，U=0．064，P〈0．05，一致性好。病理证实人乳头状瘤病毒（HPV）阳性的妇女中CIN发生率79％（67／84），而HPV阴性者中CIN发生率43．5％％（74／170），结果显示两组资料比较差异有统计学意义，X^2=29．88，P〈0．05。本组资料中年龄在35～55岁的妇女占83．5％与HPV阳性的妇女年龄高峰一致。结论对ASCUS的患者应与LSIL同样重视，立即进行阴道镜检查以避免22．9％的高度病变的患者漏诊或失访，对35～55岁的HPV感染的妇女应更加重视。

The clinical significance and management of cervico-cytologically diagnosed ASCUS/LSIL

PURPOSE: To investigate the clinical significance and management of ASCUS/LSIL. METHODS: 254 patients who were examined with cervical cytology in the Cancer Institute and Hospital Chinese Academy of Medical Sciences were ASCUS/LSIL, of whom 136 cases underwent colposcopy, Data were analyzed retrospectively according to the golden criterion of pathology outcome. RESULTS: 140 cases were ASCUS, and 114 cases were LSIL. Cervical intra-epithelial neoplasia (CIN) were diagnosed in 51.5% of patients with ASCUS, compared with 59.6% of patients with LSIL (P>0.05). High-grade cervical intraepithelial neoplasia were diagnosed in 22.9% of patients with ASCUS, compared with 30.7% of patients with LSIL (P >0.05). In the 136 patients examined with colposcopy, inflammation was found in 47 cases, low-grade intraepithelial lesion in 53 cases, High-grade intraepithelial lesion in 36 cases. The pathological results show inflammation in 55 cases, low-grade intraepithelial lesion in 41 cases, High-grade intraepithelial lesion in 40 cases (Kappa=0.314, U=0.064, P less than 0.05). CIN were diagnosed in 79% (67/84) of HPV-positive patients identified by pathology, compared with 43.5% (74/170) of HPV-negative patients (chi2=29.88 P less than 0.05). 83.5% of 254 patients were between 35 to 55 years old, and that was consistent with HPV-positive women age peak. CONCLUSION: Patients with ASCUS should be paid the same attention with LSIL patients and colposcopy examination should be done immediately to avoid missed diagnosis and missed follow-up examination, especially for HPV positive patients between 35 to 55 years old.
