RESUMO
Most cervical cancers occur in women who do not participate in cervical-cancer screening. We therefore evaluated adherence to screening for clinic-based Pap testing, self-collected sampling for HPV testing, and choice of the 2 among 483 unscreened/underscreened women in Brazil. Three public Basic Health Units (BHU) were each randomly assigned to three arms: (i) Pap testing at the BHU (N = 160), (ii) "Self&HPV" (self-collection for HPV testing) (N = 161), and (iii) "Choice" between self-collection and HPV testing and Pap test at the local BHU (N = 162). The theory-based (PEN-3 and Health Belief Model) intervention in all three arms was implemented by trained Community Health Workers (CHW) at participants' home. With the first invitation, 60.0% in the Pap arm, 95.1% [154 of 161 (95.7%) who selected Self&HPV and 0 of 1 (0.0%) who selected Pap] in the Choice arm, and 100% in the Self&HPV arm completed screening. By the second invitation to choose a method of screening in the Choice arm, 100% completed screening. After three invitations, 75.0% of women in the Pap arm completed screening. Adherence to screening differed by study arm (P < 0.001). In conclusion, Self&HPV testing is a promising strategy for unscreened/underscreened women who are recalcitrant or unable to undergo clinic-based cervical screening to complement the screening modality used in the general population. In Brazil, where Pap testing is recommended for routine cervical screening, training CHWs in behavior change strategies and offering Self&HPV or Choice could greatly improve screening population coverage by reaching the unscreened/underscreened populations.

BACKGROUND: Despite the availability of cervical cancer screening programs in Brazil, some women do not participate in these programs owing to structural and/or interpersonal/intrapersonal barriers, resulting in high cervical cancer incidence and mortality. Integrating community health workers (CHWs) into the delivery of cervical cancer screening interventions is potentially a feasible strategy to address these barriers. OBJECTIVES: This study aimed to implement and evaluate a CHW training to deliver a brief intervention to promote cervical cancer screening among underscreened and unscreened women in Brazil. METHODS: The curriculum addressed cervical cancer and screening, behavioral intervention strategies, and protection of human subjects in research. Pretest and post-test questionnaires assessed changes in CHW objective and perceived knowledge as well as perceived skills and confidence (N = 15). RESULTS: There was a significant increase in objective and perceived knowledge about cervical cancer, behavior change strategies, and protection of human subjects in research between pretest and post-test, but not in self-perception about skills and confidence to motivate women to engage in cervical cancer screening. CONCLUSIONS: Improvements in CHW knowledge about cervical cancer screening and behavior change represents a step forward toward successful interventions, but adaptations are needed to boost their self-confidence and perceived skills with regard to their ability to promote behavior change at the community level.

Significant cancer health disparities exist in the United States and Puerto Rico. While numerous initiatives have been implemented to reduce cancer disparities, regional coordination of these efforts between institutions is often limited. To address cancer health disparities nation-wide, a series of regional transdisciplinary networks through the Geographic Management Program (GMaP) and the Minority Biospecimen/Biobanking Geographic Management Program (BMaP) were established in six regions across the country. This paper describes the development of the Region 3 GMaP/BMaP network composed of over 100 investigators from nine institutions in five Southeastern states and Puerto Rico to develop a state-of-the-art network for cancer health disparities research and training. We describe a series of partnership activities that led to the formation of the infrastructure for this network, recount the participatory processes utilized to develop and implement a needs and assets assessment and implementation plan, and describe our approach to data collection. Completion, by all nine institutions, of the needs and assets assessment resulted in several beneficial outcomes for Region 3 GMaP/BMaP. This network entails ongoing commitment from the institutions and institutional leaders, continuous participatory and engagement activities, and effective coordination and communication centered on team science goals.

Cervical cancer is the second most common female tumor worldwide, and its incidence is disproportionately high (>80%) in the developing world. In the United States, in which Papanicolaou (Pap) tests have reduced the annual incidence to approximately 11,000 cervical cancers, >60% of cases are reported to occur in medically underserved populations as part of a complex of diseases linked to poverty, race/ethnicity, and/or health disparities. Because carcinogenic human papillomavirus (HPV) infections cause virtually all cervical cancer, 2 new approaches for cervical cancer prevention have emerged: 1) HPV vaccination to prevent infections in younger women (aged < or =18 years) and 2) carcinogenic HPV detection in older women (aged > or =30 years). Together, HPV vaccination and testing, if used in an age-appropriate manner, have the potential to transform cervical cancer prevention, particularly among underserved populations. Nevertheless, significant barriers of access, acceptability, and adoption to any cervical cancer prevention strategy remain. Without understanding and addressing these obstacles, these promising new tools for cervical cancer prevention may be futile. In the current study, the delivery of cervical cancer prevention strategies to these US populations that experience a high cervical cancer burden (African-American women in South Carolina, Alabama, and Mississippi; Haitian immigrant women in Miami; Hispanic women in the US-Mexico Border; Sioux/Native American women in the Northern Plains; white women in the Appalachia; and Vietnamese-American women in Pennsylvania and New Jersey) is reviewed. The goal was to inform future research and outreach efforts to reduce the burden of cervical cancer in underserved populations.
