Globally, there were 19.3 million new cancer cases and 10 million cancer deaths, with the African continent contributing approximately 1.1 million new cases and over 700,000 deaths to the global cancer burden in 2020. High quality research is required to understand the etiology and risk factors for common cancers in the region to develop context specific strategies aimed at minimizing the future cancer burden in Africa. Our study addresses a significant gap in the knowledge and resources available for training a project management (PM) workforce for cancer research in Africa. We developed and evaluated a training program to strengthen the research capacity of project managers involved in cancer research in Africa. This workshop was held in collaboration with the Men of African Descent and Carcinoma of the Prostate (MADCaP) Consortium. The PM working group of the MADCaP Consortium had previously developed a project manager toolkit to provide a structured approach to PM for cancer research in Africa. We implemented and evaluated this training toolkit in a hybrid workshop in Nigeria. Among 29 participants from 10 African institutions, PM skills improved after training by 16.6% compared with pretraining levels. In a 1-year follow-up survey, training skills remained better (80.8%) than before the training (70.8%). The training program successfully upskilled the trainees with a significant improvement in knowledge of PM practices including planning, execution, monitoring, and evaluation of projects. The majority (80%) reported an excellent training experience. PM skills training can be successfully implemented in Africa with long-term retention of knowledge geared toward developing a workforce critical for the implementation of cancer research in the region.
