The degree of agreement between HPV testing, pap smear and colposcopy in cervical dysplasia diagnosis.

MATERIAL AND

METHODS

The current study analyzed the degree of agreement between HPV testing, Pap smear, and colposcopic directed cervical biopsies. The study was performed on a group of 332 patients diagnosed and treated for cervical dysplasia at Cuza-Vodă Obstetrics-Gynecology Clinic Hospital and Suceava County Hospital between 2006 and 2011.

RESULTS

190 patients (57.23%) were positive for HPV, 56 (35%) were positive for two HPV types and 42 (22.10%) for three or more HPV types. High grade cervical squamous intraepithelial lesion (HSIL) accounted for 88 (26.5%), low grade cervical squamous intraepithelial lesion (LSIL) for 92 (27.71%), atypical squamous cells of undetermined significance (ASC-US) for 69 (20.78%) and squamous cell carcinoma accounted for 5 (1.5%) of referral Pap smears. Colposcopic directed cervical biopsies reported no pathological abnormality (negative) in 64 (19.28%), HSIL in 105 (31.62%), LSIL in 83 (25%) and other lesions in 80 (24.1%) women. Exact degree of agreement between Pap smear and cervical biopsy was fair (k = 0.5) when analyzing for high grade cervical squamous intraepithelial lesion. The high-risk HPV types 16, 18, 66 and 68 and the low-risk HPV types 11, 54, 83, and 61 were the most frequently detected HPV types.

CONCLUSIONS

The current study showed the fair agreement between Pap smear and colposcopic biopsy. Incorporation of HPV testing into the present Pap screening program has the potential to make screening for cervical cancer more effective, and a necessary prelude to assessing this is determining the prevalence of the high-risk types.
