Cancer policy differences might help to explain international variation in cancer survival, but empirical evidence is scarce. We reviewed cancer policies in 20 International Cancer Benchmarking Partnership jurisdictions in seven countries and did exploratory analyses linking an index of cancer policy consistency over time, with monitoring and implementation mechanisms, to survival from seven cancers in a subset of ten jurisdictions from 1995 to 2014. All ten jurisdictions had structures in place to oversee or deliver cancer control policies and had published at least one major cancer plan. Few cancer plans had explicit budgets for implementation or mandated external evaluation. Cancer policy consistency was positively correlated with improvements in survival over time for six of the seven cancer sites. Jurisdictions that scored the highest on policy consistency had large improvements in survival for most sites. Our analysis provides an important first step to systematically capture and evaluate what are inherently complex policy processes. The findings can help guide policy makers seeking approaches and frameworks to improve cancer services and, ultimately, cancer outcomes.
