The United States Affiliated Pacific Island Jurisdictions (USAPIJ) are politically associated to the United States (US) as US Territories (Guam, American Samoa), a US Commonwealth (Commonwealth of the Northern Mariana Islands), and as sovereign nations linked to the US through Compacts of Free Association [Federated States of Micronesia (FSM), Republic of the Marshall Islands (RMI), Republic of Palau (ROP)]. Cervical cancer incidence in the RMI is the highest in the world, mammography services are not available in the FSM and only Guam has on-island oncology services. Cancer risk factors such as obesity, tobacco, and Hepatitis B are prevalent. Twelve years of nuclear testing in the RMI adds to the cancer burden. A community-based, multi-national coalition with multi-system external partners the Pacific Regional Cancer Control Partnership (PRCP) was developed to address cancer prevention and control in the USAPIJ. Through the PRCP, local cancer coalitions, a regional cancer registry, 12 years of regional cancer control plans, and cancer prevention programs and research has been implemented.Methods: The PRCP is the subject of this community case study. The PRCP is analyzed through a socio-ecological theoretical framework to contextualize its typology, building blocks, and management. The respective roles and work of each partner and organization will be described and aligned with the levels of the socio-ecological framework.Results: The USAPIJs evolved a community-focused internal and external regional cancer prevention and control network over 20 years. The function and structure of the PRCP fits within a socio-ecological framework for cancer control. An adaptive management strategy has been used within the PRCP to manage its multi-national, multi-level, and multi-system partners.Conclusion: The PRCP has been able to advance cancer prevention and control programs with a community-centric model that functions in a multi-national, multi-cultural, low-resource, geographically dispersed environment over the last 20 years. The PRCP operates with a structure and management style that is consistent with a socio-ecological framework for cancer control. This case study provides a blueprint for the PRCP organizational structure and a mechanism for its function. The PRCP concept, a community-centric model for cancer control in multi-national resource-limited environments, may be scaled to other global environments.

Non-invasive, self-collected sampling methods for HPV DNA detection in women, which are reliable, efficient, and acceptable have the potential to address barriers to cervical cancer screening in underserved communities, including low-middle income countries (LMIC) such as the island nation of the Federated States of Micronesia (FSM). Urine-based HPV testing has not been rigorously evaluated in clinical trials. A pilot community-based participatory randomized control research project evaluated use of urine HPV testing as a more culturally- and human resource appropriate method of cervical cancer screening in Yap State, FSM. Women participated in a cervical screening intervention using pap vs. urine test (N = 217). This manuscript described attitudes about screening feasibility and preferences. Stakeholders and women participants were interviewed (N = 23), and a survey also evaluated women’s screening preferences (N = 217). Qualitative content thematic analysis with multiple coders identified themes from interviews on acceptability and feasibility of screening tests. Women research participants were comfortable with the urine test (95%), despite limitations in some to provide samples. While 82.0% indicated that they felt comfortable with Pap smear, they also preferred a clinician (42%) to do the Pap smear, explaining that they preferred having a trained worker instead of themselves to do tests. Women want to be screened but accessibility remains a challenge. Education and training of professionals and community members alike will improve clinical skills, research capacity, knowledge of screening tests and behaviors including prioritizing HPV screening and testing.

Background Non-invasive, self-collection sampling methods for human papillomavirus (HPV) DNA detection have the potential to address logistical and cultural barriers to Pap screening, particularly in under resourced settings such as Yap state in the Federated States of Micronesia – a population with low levels of screening and high incidence of cervical cancer. Methods: A randomized controlled trial was conducted among adult women in Yap to compare cervical HPV DNA in self-collected urine and clinician-collected liquid cytology. Adult women aged 21-65 (n=217) were randomized by the order of sample collection. Concordance of HPV DNA, evaluated by the Roche Linear Array, was compared in paired self-collected urine and clinician-collected liquid cytology samples. The sensitivity and specificity of urine HPV DNA for prediction of cervical HPV and abnormal cytology was also evaluated. p16 in urine cytology samples was additionally assessed. Results Overall, HPV DNA detection was significantly lower in urine than cervical samples for any HPV (27.8% and 38.3%, respectively) and high-risk HPV (15.1% and 23.8%, respectively). For paired samples, there was moderate agreement for the overall study population (Kappa=0.54, 95% confidence interval CI=0.40-0.68) and substantial agreement for women >40 years (Kappa=0.65, 95% CI=0.46-0.85). The sensitivity and specificity of urine for the detection of cervical high-risk HPV was 51.0% and 96.2%, respectively. The sensitivities of HPV DNA in urine and liquid cytology for prediction of abnormal cytology (ASCUS/LSIL/HSIL) were 47.4% (95% CI=31.0-64.2) and 57.9% (95% CI=40.8-73.7), respectively; specificities were 92.0% (95% CI=86.9%-95.5%) and 83.5% (95% CI=77.2-88.7). Urine p16 was poorly correlated with urine HPV DNA positivity. Conclusions Urine is less sensitive but more specific than directed cervical sampling for detection of cytologic abnormalities and may have utility for screening in older populations within low-resource communities when clinically-collected samples cannot be obtained.

Introduction In the early 1990s, a comprehensive cancer control (CCC) approach was developed in the United States (US). In 2003, the US-Affiliated Pacific Islands (USAPI) adopted the CCC approach through a regional coalition, the Cancer Council of the Pacific Islands (CCPI). Using the CCC approach, the CCPI developed jurisdiction-specific cancer coalitions and initiated their respective cancer plans. Methods The evolution of the CCC approach and the history of the CCPI regional coalition are reviewed. The outcomes of the regional approach for cancer control in the USAPI are described to illustrate the possibilities, value-added and innovation of using a CCC strategy in a multi-national coalition based in a resource-limited environment. Results The CCC approach enabled the CCPI to (1) harmonize cancer control efforts between the six USAPI jurisdictions, (2) represent the USAPI cancer needs as a single voice, and (3) develop a regional cancer control strategy. Outcomes include (1) a regional cancer registry, (2) three sequential regional CCC plans, (3) leveraged resources for the USAPI, (4) enhanced on-site technical assistance and training, (5) improved standards for cancer screening, (6) evidence-based cancer control interventions adapted for the USAPI. Conclusion The regional CCPI coupled with the CCC approach is an effective engine of change. The CCC strategies enabled navigation of the political, geographic, cultural, and epidemiologic Pacific environment. The regional partners have been able to harmonize cancer control efforts in resource-limited settings. Regional cancer coalitions may be effective in the global arena for cancer control between communities, states, or countries.
