Abstract
BACKGROUND: Global investment in research on noncommunicable diseases is on the rise. Cancer as primus inter pares draws particular interest from a wide spectrum of research funders. Next to the private, governmental, and academic sectors, philanthropy has carved out a sizeable area in the funding landscape over the last 25 years. Previous reports describing cancer research funding have looked at the volume of investment in cancer research but have paid little attention to building strategic intelligence on funders. Moreover, these efforts have focused primarily on well-resourced organizations, neglecting a large number of players with less-developed finances. METHODS: In this article, we combined gnostic data acquisition with agnostic bibliometrics to establish a comprehensive map of the global cancer research funding landscape. The analysis of funding acknowledgments from cancer research papers used in this exercise is a "bottom-up" method that provides a broader perspective on the variety of actors involved. It does not rely on a priori knowledge, nor does it require funders' support for access to the data. RESULTS: Using this approach, we have identified a total of 4693 organizations from 107 countries engaged in funding cancer research today. CONCLUSIONS: This is the largest mapping exercise performed to date and should serve as a knowledge base for future analyses and comparisons aimed at understanding the dynamics and priorities of global cancer research funding.
