Meanwhile, C4 collaborative online education and training with faculty from leading institutions has benefited over 370 trainees in oncology over the past 2 years with growing collaborations with other Institutions in the USA, Europe and Low and Middle Income Countries. In 2018, the C4 collaborative education approach received the American Association of Physicists in Medicine (AAPM) Award for Education Innovation Excellence. Many publications have resulted directly from the work of the GHC, highlighting innovative approaches/activities for global oncology including 2 books and many national and international conference abstracts and global health sessions. The program has also catalyzed support for the establishment of the Africa Journal of Medical Physics, online Chart Rounds, diaspora-led tumor boards, equipment donations/fellowships supporting the establishment of cancer centers in Nigeria, Rwanda, Cameroon and Kenya, and participated in development of recommendations for the USA government in global health. The program has also helped: increase opportunities to share expertise, collaborate and break down silos; Over 100 diaspora organizations have already been engaged, and a growing number of celebrities and industry partners, with increasing expressed commitments to support research and education collaborations. Today the GHC is partnering and supporting global health programs at other institutions including the Universities of Pennsylvania, University of Massachusetts, University of Heidelberg Germany, and Oxford University UK. The program has furthermore been recognized by national and international professional societies for the focused approach to catalyze global oncology collaborations, including the American Society for Radiation Oncology, AAPM, American Society for Clinical Oncology, Union for International Cancer Control, African Organization for Research and Training in Cancer, European Society for Surgical Oncology, amongst others.

In 2020, the GHC has grown into a movement for global health impact with focus on growing the initiatives that have resulted. This includes support for organizing the yearly summits now at different institutions, growing the C4 powered by artificial intelligence including the global oncology University, elevating Phytomedicines in global health, growing the new academic field of Religion and Global Health, and finally continuing to lead the way in engaging the diaspora for global health.
