title: Comparison of fluorescence in situ hybridization, hybrid capture 2 and polymerase chain reaction for the detection of high-risk human papillomavirus in cervical cytology specimens.
abstract: OBJECTIVE
  To compare a recently developed fluorescence in situ hybridization (FISH) high-risk human papillomavirus (HR-HPV) assay to Hybrid Capture 2 (HC2) (Digene Corporation, Gaithersburg, Maryland, U.S.A.) and polymerase chain reaction (PCR) for the detection of HR-HPV subtypes in cervical cytology specimens.
  
  
  METHODS
  One hundred forty-one liquid-based cytology specimens were used to produce a thin-layer slide for FISH analysis. The remaining material was sent for HC2 and PCR HR-HPV testing. Thin-layer slides were hybridized with a FISH probe set containing a biotin-labeled HR-HPV cocktail and were manually screened for HR-HPV-infected cells. Specimens with > or = 1 HPV-positive cell by FISH were considered positive for HR-HPV infection.
  
  
  RESULTS
  There was complete concordance between HC2, FISH and PCR in 104 (75%) specimens. FISH was concordant with HC2 and PCR in 120 (85%) and 115 (82%) specimens, respectively. HC2 and PCR were concordant in 118 (84%) specimens.
  
  
  CONCLUSIONS
  The concordance of HR-HPV detection between FISH and HC2/PCR appears similar to concordances between HC2 and PCR. This suggests that FISH may be another method of detecting HR-HPV while having the potential to add additional information such as integrated/episomal staining and the ability to detect chromosomal abnormalities in individual cells.
