Cancer events in Belgian nursing home residents: An EORTC prospective cohort study.

Clinically relevant cancer events (potentially requiring diagnostic or therapeutic action) occur at a much lower frequency in NHR than expected from cancer incidence data in the general older population. Although some underreporting of cancer events cannot be excluded, this prospective study supports several previous retrospective observations that cancer events are rare in very frail older persons. Moreover, diagnostic and therapeutic actions for (suspected) cancer events are often not undertaken in this population.
