RESUMO

The aim of this study was to evaluate the underlying lesions and factors predicting cervical intraepithelial neoplasia (CIN) 2+ in women who had 'atypical squamous cells of undetermined significance' (ASC-US) on cervical cytology in the region with a high incidence of cervical cancer. This study was prospectively conducted at Chiang Mai University Hospital, Chiang Mai, Thailand. All women with ASC-US cytology undergoing colposcopic evaluation between October 2004 and August 2008 were recruited. During the study period, 208 women were enrolled. Mean age was 44.4 years. The histopathologic results at the initial evaluation were as follows: CIN 2-3, 21 (10.1%); adenocarcinoma in situ, 3 (1.4%); cancer, 5 (2.4%); CIN 1, 26 (12.5%); and no lesions, 153 (73.6%). Multivariate analysis revealed that nulliparity (adjusted odds ratio [aOR] =4.09; 95% confidence interval [CI] = 1.04-16.10) and current oral contraceptive use (aOR=2.85; 95%CI= 1.14-7.15) were independent predictors for having CIN 2+ at the initial colposcopy. At the median follow-up time of 6.7 months, CIN 2-3 lesions were additionally detected in 2 women. In conclusion, ASC-US cytology in our population has a relatively high prevalence of underlying invasive carcinoma. Nulliparity and current oral contraceptive use are independent predictors for harboring CIN 2+.

RESUMO

The aim of this study was to determine the underlying pathology of women with high grade squamous intraepithelial lesion (HSIL) on cervical cytology. A total of 681 women with HSIL cytology undergoing colposcopic examination at Chiang Mai University Hospital (CMUH) between January 2000 and December 2005 were evaluated for the underlying cervical pathology. The final pathology was diagnosed from the most severe lesions obtained by punch biopsy, loop electrosurgical procedure, cold knife conization or hysterectomy. Underlying high grade cervical lesions including cervical intraepithelial neoplasia grade 2, 3 and adenocarcinoma in situ were noted in 502 (73.7%) women. Invasive cervical carcinoma was identified in 141 (20.7%). The remaining 38 (5.6%) had either low grade or no intraepithelial lesions. No significant difference in the prevalence of underlying high grade and invasive lesions was noted between women with cytologic diagnosis of HSIL from CMUH and other hospitals. In conclusion, northern Thai women with HSIL cytology are at significant risk of having underlying severe cervical lesions, and especially invasive carcinoma which is detected in approximately one-fifth of the cases.
