Background: Pacific Islanders (PI) in Guam (GU), Hawaii (HI), and the U.S. associated Pacific Islands (USAPI) experience greater cancer health disparities compared with majority populations in GU, HI, and the U.S. continent. Social determinants including geographic, socio-cultural, and economic factors are barriers to health and health care, leading to late stage diagnosis and poor survival outcomes. PIs are also highly underrepresented among cancer researchers. Aim: The University of Guam (UOG)/University of Hawaii Cancer Center (UHCC) partnership aims to grow cancer research capacity at UOG, develop cancer health disparities research at UHCC focusing on Pacific Islanders (PI), raise awareness of cancer and cancer prevention in GU, HI and the USAPI, and increase the number of cancer and biomedical scientists of PI ancestry in the U.S. Methods: An infrastructure comprised of five principal investigators and approximately 30 participating faculty, administrative staff, and community and scientific advisory members, supported by funds from the National Cancer Institute and the partnering institutions, has provided 15 years of support for cancer research, training, and outreach designed to reduce cancer health disparities and advance health equity among Pacific Islanders in GU, HI and the USAPI. Results: Fifteen collaborative research projects have been funded through the partnership. Many of these projects have focused on the prevention of unhealthy lifestyle behaviors that lead to increased cancer risk. Prepilot, pilot and full research projects address cancer health disparities of regional relevance and global importance, notably breast, cervical and oral cancers as well as tobacco and betel nut use. A betel nut cessation intervention, the first of its kind, shows promising quit rates. This research has resulted in over 80 publications, 100+ abstracts, and 9 grant awards. The partnership has recruited and trained 26 underrepresented graduate scholars in cancer health disparities, including two scholars who have since joined UOG's faculty and are now independently conducting research, participating in the partnership as investigators, and mentoring tomorrow's scientists. UOG faculty and early stage investigators continue to receive mentorship and career development support. Outreach activities have contributed to the introduction and passage of significant cancer prevention and control legislation in Guam and Saipan. Outcomes are communicated through the partnership's Website, social media, and community reports and seminars. Conclusion: The partnership has significantly increased research capacity at UOG and cultivated interest in cancer research among underrepresented minority students at the partnering institutions. A regional research infrastructure has been established, and research findings are informing public health policy and planning. Resources have been leveraged to address PI cancer health disparities in GU, HI, and the USAPI.
