Role of molecular biomarker human papilloma virus (HPV) E6 oncoprotein in cervical cancer screening

The Onco E6™ Cervical Test, based on detection of the E6 oncoprotein of HPV 16 and 18 genotypes is evaluated as a screen for the early detection cervical neoplasia in resource-limited countries. This prospective study from June 2018 to June 2019 evaluated 235 women aged 21–65 years, who came to Gynaecological Oncology Outpatient Department by VIA, cytology, E6 oncoprotein test and by colposcopy. Screen-positive women by any of the tests or women with suspicious findings were further evaluated by biopsy at colposcopy. The McNemar test was used to compare the performance of E6 oncoprotein test with other screening tests. The E6 oncoprotein positivity rate was 6.8% (n = 16) with 81.25% HPV 16 positive and 18.75% HPV 18 positive. Among VIA positive cases (n = 100), E6 oncoprotein was positive in 9% (p
