What is Geriatric Oncology?
Oncologists implementing geriatric principles to manage older patients with cancer

“Silver Tsunami”
by the year 2030, 1 of every 5 Americans will be > 65 yrs
>80 yrs is the fastest growing segment of our population
incidence and mortality of / from cancer increases with age – 60% of all cancer diagnoses and 70% of
cancer mortality occurs in persons aged 65 years and older

Perspective of age Young adults
single serious condition
dominates the clinical picture
tolerates acute, severe side effects relatively well
main goal: survival/cure
Older adults
coexists w/ multiple illnesses and significant disability
other morbid conditions may be beyond cancer
variable tolerability of specific tx, may need tailoring
main goal: survival vs QOL

Goals of cancer treatment in the older patient

Important Questions in Geriatric Oncology Is the patient going to die of, or with cancer? Is the patient going to live long enough to
suffer the consequences of cancer? Is the patient able to tolerate treatment? Are there complications of treatment that are
more common in older individuals? Is the social network of the patient adequate
to support him/her during treatment?
![Page 7: Assessment of the Older Cancer Patient](https://reader036.vdocuments.mx/reader036/viewer/2022062322/5681479b550346895db4d03d/html5/thumbnails/7.jpg)

Is the patient able to tolerate treatment?

chronological age ≠ physiologic age

ECOG PS in the elderly
80 yo woman w/ breast cancer has a sedentary lifestyle. She is able to do some light housework but has a housekeeper who does most of the heavy duty washing and cleaning. She takes a long nap after lunch most days since she was 70. She goes out daily to the grocery store at the corner of the next block to do her shopping. Once a week a friend drives her to bridge club.
ECOG PS: 0,1 or 2?

How do Geriatricians do this?
Comprehensive Geriatric Assessment (CGA)– Functional status– Comorbid medical conditions– Concomitant medications– Cognitive function– Psychological state– Social support
![Page 17: Assessment of the Older Cancer Patient](https://reader036.vdocuments.mx/reader036/viewer/2022062322/5681479b550346895db4d03d/html5/thumbnails/17.jpg)
How do Geriatricians do this?
Comprehensive Geriatric Assessment (CGA)– Functional status– Comorbid medical conditions– Concomitant medications– Cognitive function– Psychological state– Social support
time consuming (60-90 min) multidisciplinary
![Page 18: Assessment of the Older Cancer Patient](https://reader036.vdocuments.mx/reader036/viewer/2022062322/5681479b550346895db4d03d/html5/thumbnails/18.jpg)
Research opportunity
Assessments using CGA – Predicts morbidity and mortality in cancer patients1
– Identifies needs and clinical problems2
– No data yet that it improves outcome
Not practical in the busy oncology clinic – Time consuming– Lack skills/tools
Newer versions– abbreviated forms of CGA (“mini-CGA”)1,3
– Self-administered CGA4,5
![Page 19: Assessment of the Older Cancer Patient](https://reader036.vdocuments.mx/reader036/viewer/2022062322/5681479b550346895db4d03d/html5/thumbnails/19.jpg)
Assessment and stratification of the older cancer patient
a.k.a. who shouldn’t you treat?– Which variables are important?
Age? Functional status? Comorbid medical conditions? Cognitive fxn? Psychological state? Social support?

I. Review of the literature ECOG and age were poor proxies for fxnl
status1
dependence >1 ADL associated with risk of mortality and chemotherapy-induced toxicity.2
comorbidity is associated with life expectancy and treatment complications.3
VES-13 predicts death and fxnl decline in vulnerable older people4
VES-13 detected geriatric impairment in older pts w/ Prostate Cancer (similar to CGA)5

II. Secondary data analysis
A) Goals– identify the most important predictors of survival in
older cancer patients
B) Available data sets– VA Data set with Dr. Dhanani– Longitudinal Studies On Aging II (LSOA II)– Health and Retirement Study (HRS)

Intermediate Outcomes
Surrogate endpoint: Does the patient make it to 1st re-staging CT or PET (2-3 months)

IV. Validation Study (TORI network)25+ group of community oncology
practicesLargely in California, but also sites
across U.S.AResearch infrastructure already in
place
Development of a quick self-assessment tool that can be used by a busy oncologist to identify metastatic cancer patients who would be least likely to benefit from chemotherapy.
