Prevention of cervical cancer in HIV-seropositive women from developing countries through cervical cancer screening: a systematic review

Conclusion: Although cervical cancer screening exists in almost all developing countries, what is missing is both opportunistic and systematic organised population-based screenings. Cervical cancer screening programmes need to be integrated into already existing HIV services to enable early detection and treatment. There is a need to offer opportunistic and coordinated screening programmes that are provider-initiated to promote early identification of cervical precancerous lesions.

Implementing community-based cervical cancer screening programs using visual inspection with acetic acid in India: A systematic review

Conclusion: Three major themes were identified that facilitated implementation of screening programs in a community-based setting: standardized training that maintained competency of test providers; collaborations with community-based organizations that used health education for recruitment of participants; and employing the screen-and-treat method to reduce loss to follow-up. Summarized evidence presented in this review could substantially influence future implementation and sustainment of cervical cancer screening programs at a national level.
