Important Points
• The US population is aging
• Cancer is associated with age
• The number of older cancer patients and survivors
will increase
• The majority of cancer mortality occurs in older adults
• Other medical conditions increase with age
• There are not enough geriatricians to care for older
adults with cancer.
Assessing Older Adults

– Chronological age
– History and Physical Examination
– Functional Status

Geriatric Assessment….
The Value of Geriatric Assessment
Uncovers problems not found routinely
 Many problems have beneficial interventions

– Improve function
– Quality of life
– Survival
Allows for accurate life-expectancy estimate
 Can predict cancer related toxicity


Molecular Aging….
p16 (CDKN2A)

Cyclin-dependent kinase inhibitor 2A
– inhibits CDK4

Codes tumor suppressor protein
– helps regulate the cell cycle
mutations increase risk of
developing a variety of cancers
 Increased expression with aging
 Ned Sharpless UNC world expert

Interventions….
Walking Intervention
• Leigh Callahan UNC
• Effective in Arthritis
↓ pain and stiffness
• Scalable
Pt sets pace
Can do anywhere
• Goal 30 min 5 x weeks
• Pilot trial In AI and now
R-21 randomized trial
