Although the majority of cancer patients in the United States are aged
65 years or older, research is showing such older adults are markedly underrepresented
in trials of cancer therapies.
Older adults make up 63% of US cancer patients but comprise only 25%
of participants in clinical cancer treatment trials. This underrepresentation
continues to affect research results and patient care, researchers say.
The problem is not new. But despite the fact that awareness of the imbalance
and suggestions for correction have appeared for years (N Engl J Med. 1999;341:2061-2067), the disproportionate lack of older
patients in clinical cancer trials persists .
