Proportion of patients with a geriatric event according to cancer site and age. Age stratified into three groups: age 55 to 64, age 65 to 74, and age ≥ 75 years. Proportions are derived from the number of patients with at least one geriatric event divided by the number of patients treated surgically. The association between geriatric events and age was assessed by using χ2 testing and found to be significant for all sites (P < .001).
