Comprehensive Nutritional Geriatric Assessments in Identifying Malnutrition in Older Cancer Participants

PRIMARY OBJECTIVES: I. To evaluate whether nutritional status, as determined by each of 4 screening tools (Mini Nutritional Assessment \[MNA\], weight loss, body mass index \[BMI\], and lean muscle mass), correlates with 6-month and 12-month mortality in older cancer patients after geriatric assessment, after adjusting for covariates. II. To evaluate whether nutritional status, as determined by each of by 4 screening tools (MNA, weight loss, BMI, and lean muscle mass) correlates with 6-month and 12-month unplanned hospitalization in older cancer patients who undergo geriatric assessment, after adjusting for covariates. III. To evaluate whether nutritional status, as determined by each of 4 screening tools (MNA, weight loss, BMI, and lean muscle mass) correlates with 6-month and 12-month hospital readmissions in older cancer patients who undergo geriatric assessment, after adjusting for covariates. OUTLINE: Participants undergo nutritional geriatric assessment over 15 minutes in person or on the phone every 3 months for 12 months.
