OBJECTIVE: The cytological features associated with clinical outcome of 'LSIL cannot exclude HSIL (LSIL-H)' in comparison with 'atypical squamous cells cannot exclude HSIL (ASC-H)' are incompletely described.
METHODS: LSIL-H and ASC-H Pap tests reported in a regional laboratory during a 13-month period were reviewed by two pathologists. Cytological features suspicious for HSIL were evaluated against a check list of 52 atypical features. All histology over 2 years of follow up for tests reclassified as LSIL-H and ASC-H was retrieved to determine clinical outcome. Atypical cytological features were correlated with outcome.
RESULTS: The review yielded 89 LSIL-H and 86 ASC-H. The highest ranked atypical cytological feature in each group was increased nuclear cytoplasmic ratio. Clinical outcome was positive (CIN II/III or AIS) in 44 (49%) LSIL-H and 33 (38%) ASC-H. Round (P = 0.02) and naked nuclei (P = 0.009) were significant correlates of outcome amongst LSIL-H tests, but no feature correlated with outcome in the ASC-H group.
CONCLUSIONS: LSIL-H is different to ASC-H because of the 11% higher frequency of a positive outcome and the cytological features associated with outcome.
