title: Abnormal uterine cervical cytology in a large tertiary hospital in Bangkok metropolis: Prevalence, management, and outcomes.
abstract: OBJECTIVE
  To determine the prevalence of abnormal cervical cytology, management, and association with clinical significant histopathology including cervical intraepithelial neoplasia II or adenocarcinoma in situ and more severe lesions.
  
  
  METHODS
  Women with abnormal cervical cytology from January 2005 to December 2009 were identified from the archives of Department of Anatomical Pathology and Department of Obstetrics and Gynecology. Demographic data, type of abnormal cytology, management, and their associated histopathology were collected.
  
  
  RESULTS
  During the study period: 2533/54,179 women (4.7%) had abnormal cervical Pap test. Squamous lesions were more common than glandular lesions: 2309 (4.3%) compared to 224 (0.4%). Atypical squamous cell (ASC) was most commonly found (1449 or 2.7%), whereas low-grade squamous intraepithelial lesion (LSIL) and high-grade squamous intra-epithelial lesion (HSIL), or squamous cell carcinoma (SCC) were found in 648 (1.2%) and 212 (0.4%), respectively. Among abnormal glandular cytology, atypical glandular cell (AGC) was most commonly found (199 women or 0.4%) whereas adenocarcinoma and endometrial cell in woman aged >40 year were found in only 14 (0.02%) and 11 women (0.02%), respectively. Majority (77.3%) underwent further investigations. We found that 13.0% of ASC, 20.3% of LSIL, and 78.7% of HSIL and SCC had clinical significant histopathology. In glandular abnormalities: 14.9% of AGC, 33.3% of women aged >40 years with endometrial cell, and 66.7% of adenocarcinoma were histologically proven to be of clinical significant.
  
  
  CONCLUSIONS
  ASC was the most common abnormal cervical cytology. Cytology abnormalities of HSIL and SCC had the highest association with clinical significant histopathology.
