Global, Regional, and National Cancer Incidence, Mortality, Years of Life Lost, Years Lived With Disability, and Disability-Adjusted Life-years for 32 Cancer Groups, 1990 to 2015

Abstract

In 2015, cancer caused over 8.7 million deaths globally and was the second leading cause of death behind cardiovascular diseases.¹ Even though these impressive numbers are testimony that the “war on cancer” has not been won, recent developments in personalized medicine and novel treatment approaches like immunotherapy have raised hope of significantly improving cancer survival.^2-4 These expectations for patients with cancer in high-income countries contrast with the challenge of making basic diagnostic and treatment options widely available in low-resource settings.⁵ Both the equity and affordability of cancer care from individual and societal perspectives are increasingly being questioned.⁶ Survival rates between and within high-income countries differ for reasons such as variation in education, access to specialized care, effective treatment, and insurance status.^7-9 The full potential of cancer prevention for reducing incidence and mortality is far from being realized, and efforts are especially lagging in low-income countries.¹⁰ Awareness of this “cancer divide,” with substantially worse outcomes and a high burden in socioeconomically disadvantaged populations, has led to a focus on global oncology by the international health community.^4,5,10 This is reflected in the third Sustainable Development Goal (SDG) to “by 2030, reduce by one-third premature mortality from non-communicable diseases through prevention and treatment and promote mental health and well-being.”¹¹ Estimates of the burden of cancer are produced annually as part of the Global Burden of Disease (GBD) study providing a unique means of tracking progress in closing this divide. Here, we present results of the GBD 2015 study for 32 cancer groups covering cancer incidence, mortality, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life years (DALYs) for 195 countries or territories from 1990 to 2015 for both sexes across age groups.
