Global Cancer Survival Varies Drastically

The rates of surviving for 5 years following a diagnosis of cancer vary widely across the globe, according to a recent study published in The Lancet.

The authors of the study state these data indicate that “Continuous worldwide surveillance of cancer survival should become an indispensable source of information for cancer patients and researchers and a stimulus for politicians to improve health policy and health-care systems.”

Researchers recently conducted a study in an attempt to understand cancer survival rates around the globe, as these data are scarce. The study included data from 67 countries and included records from 25.7 million adults and 75,000 children diagnosed with cancer during 1995-2009.

Developed countries in the world had a significantly higher rate of 5-year survival among cancer patients than many undeveloped countries. Although this fact is not surprising, some of the differences in rates of specific cancers were so drastic that the authors stated the data “suggests major deficiencies in the management of a largely curable disease.”

Worldwide efforts continue in an attempt to bring improved screening and treatment measures to developing countries; however, provisions of healthcare to impoverished countries remains a difficult task.
