Screening technologies for cervical cancer: Overview

Cytojournal. 2022 Mar 29;19:23. doi: 10.25259/CMAS_03_04_2021. eCollection 2022.ABSTRACTEver since the introduction of the Papanicolaou (PAP) smear test was published in 1941 in American Journal of Obstetrics and Gynecology, PAP test linked with definitive treatment has prevented millions of women from cervical cancer in the developed countries. Due to limited availability of resources, a lack of infrastructure and difficulty in getting highly trained professionals, widespread implementation of PAP test dependent cervical cancer screening program has not been established in low and middle income countries such as India. Therefore, after availability of non-cytological tests such as visual inspection on acetic acid (VIA) and human papillomavirus (HPV) DNA test, there is a paradigm shift in cervical cancer screening methods. In past two decades, various research work has convincingly established the utility of VIA and HPV test in developing countries. The evidences were evaluated by the World Health Organization (WHO) and recommendations have been recently published for comprehensive cervical cancer control strategies for the low and middle income countries. For any successful screening program, achieving high coverage (>70%) of the target population rather than frequent screening is the most important determinant. It is also equally important to ensure appropriate investigations of the screen positive women to establish the disease and treatment of the screen detected cases...
