Prevalence of high grade squamous intraepithelial lesions (HSIL) and invasive cervical cancer in patients with atypical squamous cells of undetermined significance (ASCUS) from cervical pap smears.
To determine the prevalence and factors associated with histologic diagnoses of High Grade Squamous Intraepithelial Lesions (HSIL) or invasive cervical cancer in women with a cytologic diagnosis of atypical squamous cells of undertermined significance (ASCUS), medical records of women with an ASCUS Pap smear from January 2003 to December 2006 were reviewed. Of 287 women with ASCUS Pap smears in whom data were available, 189 were annotated with "favoring a premalignant or malignant process", 74 with "favoring reactive", and 24 with "not otherwise specified". The prevalences of HSIL and invasive cervical cancer were 9.1% and 1.2%, respectively. Only subtypes of ASCUS were significantly associated with the detection of HSIL or invasive cancer, 12.7% with favoring premalignant or malignant process, 2.7% with favoring reactive, and 16.7% in with ASCUS-NOS (p=0.034).
