摘要:
目的 评估细胞学、高危型人乳头瘤病毒(high risk human papillomavirus, HR-HPV)与阴道镜结果的不同组合发生宫颈上皮内瘤变≥2级(cervical intraepithelial neoplasia grade 2 or worse, CIN2+)的风险。 方法 选取2018年1月-2018年12月深圳市妇幼保健院阴道镜门诊数据库中822例患者的临床数据资料,基于细胞学、HR-HPV和阴道镜结果,分析患者发生CIN2+的风险差异。 结果 若发现其中两种检查结果高度异常(细胞学高度上皮内瘤变及以上(high-grade squamous intraepithelial lesion or worse, HSIL+)、HPV16/18+、阴道镜高级别病变),则发生CIN2+的风险高于60%;若发现三种高度异常,则发生CIN2+的风险为97.1%。 结论 当发现细胞学、HR-HPV和阴道镜结果中≥2种异常情况,未来进展为CIN2+的风险较高,应予以重视,减少不必要的误诊和漏诊。 Abstract:Objective To evaluate pooled risk of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) based on the various combinations of cytology, HR-HPV (high risk human papillomavirus), and colposcopy impression. Methods A total of 822 cases were selected from the colposcopy outpatient database of Shenzhen Maternity & Child Healthcare Hospital from January to December 2018. We assessed the risk of CIN2+ based on the combinations of three test results (cytology, HR-HPV, and colposcopy). Results If two of the test results were found highly abnormality (HSIL+, HPV16/18+ and high-grade colposcopic impression), the risks for CIN2+ was higher than 60%. If three highly abnormal test results were found, the risk for CIN2+ was 97.1%. Conclusio When at least two abnormal results in cytology HR-HPV and colposcopy are found, the CIN2+ risk was quite high. Attention should be paid to reduce unnecessary misdiagnosis and missed diagnosis. -
