Analysis of clinical diagnostic methods for cervical intraepithelial neoplasia

Objective To evaluate the diagnostic methods for cervical intraepithelial neoplasia(CIN),including cervical cytological smear,colposcopic examination and colposcopically multiple biopsy Methods 195 patients with abnormal cervical smears underwent colposcopic examinations and biopsies The results of cytological screening compared with the results of histologic-colposcopic diagnosis were analyzed retrospectively Results Among 90 cases with atypical squamous cell of undetermined significance(ASCUS),26(30%)were inflammation,52(57 78%)were cervical intraepithelial neoplasia Ⅰ(CIN Ⅰ)and 6(6 67%)were CIN Ⅱ,5(5 56%)were CIN Ⅲ Among 71 cases with low grade squamous intraepithelial lesion(LSIL),17(23 94%)were inflammations,45(63 38%)were CIN Ⅰ and 9(12 68%)were CIN Ⅱ and Ⅲ Among 28 cases with high grade squamous intraepeithelial lesion(HSIL),8(28 57%) were CINⅠ and 18(57 14%) were CINⅡ,Ⅲ or carcinoma in situ(CIS) Conclusions Patient with abnormal cytological finding should undergo colpscopic examination and multiple biopsies for further diagnosis Women with the sex action should receive cytological screening or colposcopic examination regularly
