title: Treatment of the patients with abnormal cervical cytology: a "see-and-treat" versus three-step strategy.
abstract: OBJECTIVE
  To examine the correlation between cervical cytology and final histological results in patients who have undergone loop electrosurgical excision procedure (LEEP) with or without colposcopy-directed biopsy.
  
  
  METHODS
  A retrospective review was performed of 829 patients who underwent LEEP for abnormal cervical cytology at Gangnam Severance Hospital between January 2004 and December 2008. Patients were classified to three groups according to cervical cytology and also divided into two groups based on the treatment they received: see-and-treat group and the standard three-step group. Final histological results were compared for the each study group.
  
  
  RESULTS
  There were no differences in the final histological results between see-and-treat and three-step group in patients with high-grade squamous intraepithelial lesions (HSIL) cytology (N=523) (p=0.71). However, in patients with low-grade squamous intraepithelial lesions (LSIL)/atypical squamous cells of undetermined significance (ASCUS) (N=257) or normal cytology (N=49), the final histological results were significantly different between see-and-treat and three-step group (p<0.001) and the rate of overtreatment was significantly higher in the see-and-treat group (p<0.001).
  
  
  CONCLUSIONS
  A see-and-treat protocol may be a viable alternative only in patients with HSIL cytology if colposcopic impression is suggestive of cervical intraepithelial neoplasia (CIN) 2 or 3 lesions.
