Overview

Background Cancer is a major cause of mortality worldwide, and differences in cancer mortality rates between countries are, in part, due to differences in access to cancer care, including medicines. National essential medicines lists (NEMLs) play a role in prioritization of healthcare expenditure and access to medicines. We examined the association between amenable cancer mortality and listing medicines used in the management of eight cancers (non-melanoma skin, uterine, breast, Hodgkin lymphoma, colon, leukemia, cervical, and testicular) in national essential medicines lists of 158 countries and summarized changes to the inclusion of cancer treatments in NEMLs. Methods We conducted a cross-sectional examination of NEMLs for 158 countries, which were obtained in May 2023. We identified medicines used to treat each of the eight cancers and determined the number of medicines listed by NEMLs for each cancer. We conducted multiple linear regressions to examine the association between the number of medicines listed on the NEMLs and cancer mortality. Results We found associations between cancer medicine listing and outcomes for six of the eight examined cancers (non-melanoma skin cancer ( p  = 0.001), uterine cancer ( p  = 0.006), breast cancer ( p  = 0.001), Hodgkin lymphoma ( p  = 0.021), colon cancer ( p  = 0.006), and leukemia ( p  = 0.002)), when adjusting for healthcare expenditure and population size. Conclusion There was an association between listing cancer medicines on NEMLs and cancer mortality. Further research is required to explore how cancer mortality may be impacted by other cancer interventions, as well as policies to improve equitable access to cancer care.
