In the United States, more than one million people will be diagnosed with cancer this year, and that number is expected to double by 2050 as the population increases and ages. In addition, as survival improves for many cancers, the number of cancer survivors is also likely to increase. However, there are few estimates available of the long-term burden of illness that occurs in addition to the cost of medical care associated with being a cancer survivor.
To better estimate the burden of surviving cancer, Robin Yabroff, Ph.D., of the National Cancer Institute, and colleagues from NCI and the Agency for Healthcare Research and Quality analyzed data collected in the 2000 National Health Interview Survey, an annual survey that asks respondents questions about their lives and health. The researchers analyzed responses from more than 1,800 cancer survivors and nearly 5,500 control subjects who were matched for age, sex, and level of education.
Cancer survivors had a lower quality of life, more lost productivity, and more health limitations than the control subjects, and this high level of burden was seen even beyond 10 years after their diagnosis. While these differences existed across all tumor sites, survivors of cancers that typically have shorter survival times, such as lung cancer, reported a greater level of burden from their disease compared with survivors of breast, colorectal, prostate, and other cancers. The authors suggest that this difference may reflect a greater proportion of people with cancers that typically have shorter survival times being more likely to have metastatic or, at least, active c
