The clinical significance of detecting P16 protein in cervical cell block of ASCUS / 中国医师杂志

ABSTRACT

Objective Through the cell block technique to detect the expression of P16 protein in the liquid-based cytology with atypical squamous cells of undetermined significance (ASCUS) and high degree of cervical intraepithelial lesions (HSIL),to explore the significance of P16 protein in ASCUS re-evaluate.Methods Collected in our hospital in 2012 cervix liquid based cytology specimens of 45 patients,including of 15 ASCUS,11 HSIL cases,low in 11 cases of epithelial lesions (LSIL) and 2 cases of squamous cell carcinoma,2 cases of atypical glandular cells,4 cases of normal cells as a control.Immunocytochemical analysis of P16 protein control analysis,cytology and histology results.Results The expressing of P16 protein in normal cells,ASCUS,LSIL,HSIL,squamous cell carcinoma,atypical glandular cells in the positive expression rates were 0,20％,27.2％,63.6％,100％,100％.Cytology and biopsy results,cytologic diagnosis of ASCUS 15 cases,biopsy12 cases of cervicitis,CIN Ⅱ-Ⅲ in 3 cases; cytology the in LSIL11,biopsy5 cases of cervicitis,CIN Ⅰ 6 cases ; the cytological diagnosis HSIL11 cases,biopsycervical four cases of intlammation,CIN Ⅱ-Ⅲ ; cytologic diagnosis of atypical glandular cells in 2 cases,biopsyadenocarcinoma; cytologic diagnosis of squamous cell carcinoma in 2 cases,biopsysquamous cell carcinoma.Conclusion Detection of P16 protein on the cell block can be used for ASCUS classification ASCUS reassessment.
