Pilleron S, et al. - Researchers analyzed global trends in cancer incidence in 2012 among older adults. They also assessed the changing scale of cancer in this age group over the next decades. For this purpose, they used GLOBOCAN 2012 data. Among adults aged 65 years and older, the truncated age-standardized incidence rates for all cancer sites combined and for the five most common cancer sites by world region were determined. Globally, 6.7 million new cancer cases (47.5% of all cancers) were diagnosed among older adults in 2012 with almost half of these developing in less developed regions. Data also showed marked regional disparities, but generally lung, colorectal, prostate, stomach and breast cancers accounted for 55% of the global incidence. Compared to 54% in more developed regions, less developed regions will see an increase of new cases by 144%. Findings are suggestive of substantial economic and social impacts of the expected increase in cancer incidence at older ages, globally, and this will pose considerable and unique challenge especially in regions with limited resources and weaker health systems.
