VIA Screen-and-Treat Cervical Cancer Prevention in Guyana: A Mobile Clinic PilotProject to a Remote Amerindian Community John E. Varallo, MD, MPH, FACOG - Omni Med, Waban, MA; and Orrin Liddell, MBBS - Dept. of Obstetrics and Gynaecology, Georgetown Public Hospital Corporation, Georgetown, Guyana Guyana suffers among the highest cervical cancer rates in the world (1) Methods Conclusions/Policy Implications • A two day cross-sectional study of women living in and around Moruca, an Amerindian village in the remote interior of Guyana. • Except for the lead author, all mobile clinic personnel were Guyanese. Team members were trained/supervised by the lead author. • All necessary equipment and supplies were transported to the remote clinic site by the mobile clinic team. • VIA screening was conducted in the mornings, following a strict protocol. • Screen-positive women were treated the same afternoon as their screening. Treatment consisted of Loop Electrosurgical Excision Procedure (LEEP). • Tissue specimens were processed at Guyana’s main referral laboratory. • Cervical cancer prevention using VIA combined with same-day treatment in a mobile clinic in Guyana is feasible, accurate, safe, and highly acceptable. • This low-cost strategy is a practical alternative to dramatically expand coverage of cervical cancer prevention services in settings such as Guyana. • A national policy for cervical cancer prevention based on this model (using both Cryotherapy and LEEP for treatment) has been accepted in principal. • HPV typing and possible vaccination are being considered for incorporation into the national policy. • Main reasons for such high cervical cancer rates • Major logistical and technical barriers associated with traditional, multistep, cytology-based screening, such as: • Poor access to screening and treatment services • Poor linkage of screening with treatment • Limited cytopathology services 2. Sociocultural, behavioral, and HPV issues Training at main public hospital Travel to interior via multiple boat trips up rivers Moruca - main street/boat launch Mobile clinic waiting area Acknowledgements The authors would like to thank the following for their continued support and encouragement: Dr. Ed O’Neil and Omni Med; Dr. Madan Rambaran and Georgetown Public Hospital Corporation; Dr. Leslie Ramsammy, Sonya Roopnauth and the Ministry of Health; and Patricia Singh and the Regional Health Services. • High VIA screen-positive rate in this population at 37.5% (27/72), compared to a previous study that revealed a 17% VIA screen-positive rate in the capital city of Georgetown (6).
