Abstract
OBJECTIVE
Cervical intraepithelial neoplasia (CIN) and invasive cervix cancer were detected in some cases of atypical squamous cells of undetermined significance (ASCUS) PAP smear. So it is reasonable to evaluate and manage ASCUS PAP smear. In this study, we attempted to assess the clinical significance of a cytologic diagnosis of ASCUS and determine the usefulness of HPV DNA chip test (which is a new diagnostic method for HPV) in management and evaluation of ASCUS patients. METHODS: This study was performed from November 2001 to June 2002 and included 48 cases of ASCUS. They were evaluated by HPV DNA chip test and the pathology was evaluated by punch biopsy, cone biopsy or hysterectomy. The result of type 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68 and 69 in HPV DNA chip test were categorized as high risk. RESULTS: The rate of CIN II or above in ASCUS was 18.8% (9/48). The detection rate of high risk HPV DNA in ASCUS was 41.7% (20/48). The detection rate of high risk HPV DNA was 30.6% (11/36) in normal or reactive, 33.3% (1/3) in CIN I, 80% (4/5) in CIN II, 100% (2/2) in CIN III, 100% (2/2) in invasive cervix cancer. Higher the grade of pathology, more the detection rate of high risk HPV DNA chip test. The sensitivity for the prediction of CIN II or above by HPV DNA chip test was 88.9% and specificity was 69.2%, respectively. CONCLUSION: The use of HPV DNA chip test in patients with ASCUS may provide usefulness in detection of CIN II, CIN III and invasive cervix cancer.
