摘要目的：探讨鳞状上皮细胞癌抗原（SCC-Ag）联合液基薄层细胞检测（TCT）在宫颈病变筛查中的应用价值。方法TCT检测提示异常的58例患者，行病理活检，同时进行血清SCC-Ag检测，以病理活检为诊断标准，计算TCT与SCC-Ag联合检测筛查宫颈病变的敏感度、特异度，评价两者联合检测的诊断价值。结果 TCT检测的敏感度和特异度分别为75％和65.8％；SCC-Ag检测的敏感度和特异度分别为60％和86.9％；两者联合检测的敏感度和特异度分别为55％和89.4％。 TCT检测与SCC-Ag检测差异有统计学意义（ P ＜0.05），两者联合检测与单一TCT检测差异有统计学意义（ P ＜0.05）。结论TCT与SCC-Ag联合检测可提高宫颈检测的特异度，在宫颈病变筛查中具有一定的临床应用价值。

abstractsObjective To explore the application of thinprep cytology test thinprep cytologic test ( TCT) and the serum squa-mous cell carcinoma antigen ( SCC-Ag) measurement in the cervical lesions screening .Methods TCT and serum SCC-Ag measure-ment were performed in 58 patients with cervical lesions .Based on pathology diagnosis , specificity and sensitivity of these two screen-ing methods were calculated .Results Sensitivity and specificity of TCT detection were 75%and 65.8%, the sensitivity and specific-ity of SCC-Ag detection was 60%and 86.9%, respectively, and specificity of combined detection were 55%and 89.4%, respective-ly.There was statistical significance in TCT test and SCC-Ag test ( P <0.05 ) , the difference had statistical significance of combined detection of both with a single TCT to detect differences ( P <0.05 ) .Conclusions The combination of TCT and SCC-Ag detection can improve specificity and there was a certain clinical application value in the screening of cervical lesions .
