Abstract
Cervical carcinoma (CC) is the fourth most common malignancy among women. Screening with Papanicolau smear is linked to a reduction in CC incidence rates when screening programs have been developed. However, this technique has several limitations, including moderate sensitivity rates for detection of cervical preneoplastic HPV-related lesions. In this real-world study, we proposed to evaluate the sensitivity and specificity rates of cobas® test, which amplifies target DNA fragments by polymerase chain reaction and hybridization of nucleic acids for the detection of 14 HR-HPV types in a single analysis) used as primary screening test for CC and preneoplastic lesions in women aged 25-65 years in a large University Hospital in Buenos Aires. A total of 1044 patients were included in the sample (median age: 46 years); sensitivity and specificity rates for the HR-HPV test used as primary screening test were 98.66% (95% confidence interval [95CI]: 97.67-99.3%) and 87.15% (95CI: 84.93-89.15%), respectively. The positive predictive value was 88.47% (95CI: 86.54%-90.42%) and the negative predictive value was 98.48% (95CI: 97.75%-99.23%). The cobas® HR-HPV testing was highly sensitive and specific for the detection of CC and preneoplastic lesions in real practice.
