Risk factors for adverse events in patients with breast, colorectal, and lung cancer.

This retrospective cohort study identified frequent treatment-related adverse events for patients with breast, colorectal, or lung cancer, with 34% of patients experiencing an adverse event during their treatment course. Advanced disease and chemotherapy conferred higher risk for adverse events, as did non-White race and Hispanic ethnicity. The authors suggest that such factors could be used for prospective identification of patients at highest risk for adverse events.
