不孕症妇女宫颈细胞学异常的分析

目的应用液基细胞学比较不孕妇女和正常育龄妇女宫颈细胞学异常的发生率。方法应用为期2年以上的回顾性病例对照研究方法,比较病例组(290例)和对照组(5132例)的宫颈细胞学异常发生率。病例组包括所有在治疗不孕过程中应用了宫颈细胞学检查的不孕症妇女,并细分为原发性和继发性不孕。对照组为同期进行宫颈细胞学筛查的正常育龄妇女。两组患者的年龄和人口组成特点相似。应用卡方检验进行统计分析。结果病例组(25/290,8.6%)与对照组(67/5132,1.3%)宫颈鳞状上皮病变比较差异有统计学意义(P<0.05)。继发性病例组比原发性病例组上皮细胞异常发生率更高,病损级别更高。结论在相似的年龄及人口组成特点下,病例组较对照组在统计学上上皮细胞损伤的发生率更高。经常进行宫颈细胞学筛查对于不孕不育的妇女有益。

Analysis of abnormal cervical cytology in women with infertility

Objective To compare the incidence of abnormal cervical cytology in infertile women and normal women of similar age by using liquid-based cytology tests (ThinPrep pap test). Methods A retrospective case-control study over a period of two years was conducted. The study group (n=290) included infertile women undergoing liquid-based cytology tests in the treatment, which were subdivided into primary infertility subgroup and secondary infertility subgroup. The control group (n=5 132) included women without infertility problems who received routine liquid-based cytology test in the same period. Age and demographic characteristics were similar in the two groups. Chi-square test was used for statistical analysis. Results The study group showed significantly (P<0.05) more cervical squamous epithelial abnormalities (25/290, 8.6%) than the control group (67/5132, 1.3%). Women with secondary infertility had more epithelial abnormalities and more high-grade lesions than women with primary infertility. Conclusion Infertile women tend to have statistically significant higher incidence of squamous intraepithelial lesions than women without infertility problems of similar age and demographic background. Women with infertility might benefit from more frequent cervical cytology screening.
