|Abstract:||Objective: This study analyzed whether HPV (human papillomavirus) testing contributes towards defining histological abnormalities in women with atypical glandular cells (AGC) diagnosed at cervical cytology. Study design: One hundred and eight women with conventional cervical cancer screening smears suggestive of AGC not otherwise specified (AGC-NOS) and favor neoplastic (AGC-FN) were consecutively enrolled. All women underwent colposcopic examinations and biopsy was performed according to the cytopathologic and/or colposcopic abnormalities present. All specimens were tested for high risk HPV genotypes by Roche's polymerase chain reaction reverse line blot assay. The chi-square test was used to evaluate the association between HPV findings and a diagnosis of high-grade pre-invasive or invasive disease (CIN 2 or worse) taking negative tests or CIN 1 as a reference. Odds ratios (OR) with their respective 95% confidence intervals (95%CI) were used to evaluate the magnitude of the association between HPV testing and CIN 2 or worse. Sensitivity, specificity and their respective 95% confidence intervals (95%CI), positive predictive values (PPV) and negative predictive values (NPV) were also calculated. Results: Final diagnosis revealed a negative outcome in 80 cases (74%), cervical epithelial neoplasia 1 (CIN 1) in 13 cases (12%), CIN 2 or worse in 12 cases (11%) and glandular neoplasia in 3 (3%) cases. The overall detection rate of HPV was 21% (23/108). Neoplasia was significantly associated with positive HPV-DNA in women with AGC-NOS (OR = 15.21; 95%CI: 2.64-87.50); however, there was no significant association between a histological diagnosis of neoplasia and HPV positivity in women with AGC-FN (OR = 3.00; 95%CI: 0.36-24.92). The sensitivity, specificity, positive predictive value and negative predictive value of HPV-DNA testing for the detection of CIN 2 or worse in women with AGC-NOS were 71%, 86%, 29% and 97%, respectively. In women with AGC-FN, these values were 50%, 75%, 66% and 60%, respectively. Conclusions: HPV testing at the time of colposcopy for patients with AGC in whom no colposcopic abnormality is found may be a powerful ancillary tool for identifying women at a high risk of underlying significant cervical lesions. © 2011 Elsevier Ireland Ltd.
