Introduction
⚫ CRC is predominantly a disease of the elderly
⚫ Treatment guidelines are largely based on
randomised trials involving only small numbers
of fit older patients
⚫ It is unclear whether treatment regimens that
are beneficial for younger patients are also the
best choice for the older population given their
heterogeneity in physiological reserves, co-
morbidities, functional status, and cognition.

Geriatric assessment (1)
⚫ Functional status
⚫ Psychological health
⚫ Polypharmacy
⚫ Co-morbidities
⚫ Nutrition
⚫ Social support
⚫ Cognition

Geriatric assessment (2)
Why bother in cancer patients?
⚫ Can identify areas of vulnerability even in
patients with ECOG PS (0,1)
⚫ Can predict survival and adverse events
during treatment (retrospective data)
⚫ Can identify areas where interventions can be
performed, such as dietary advice, physical
therapy, and social support

Primary aim:
⚫ Estimate the progression free survival of anti-EGFR +combination
chemotherapy by age (>= 70 yrs vs. <70 yrs) in patients with advanced
colon cancer.
⚫ Examine the pattern or severity of adverse events by age (>= 70 yrs vs.
<70 yrs).
⚫
Secondary aims:
⚫ Estimate the overall survival of anti-EGFR +combination chemotherapy
by age (>= 70 yrs vs. <70 yrs) in patients with advanced colon cancer.
⚫ Estimate the response rate of anti-EGFR +combination chemotherapy by
age (>= 70 yrs vs. <70 yrs) in patients with advanced colon cancer.
⚫ Examine the pattern of dose-intensity by age (>= 70 yrs vs. <70 yrs).

Overall conclusions - recommendations
⚫ Embracing the concept of individualized treatment is an absolute requirement for
further improvements in the management of these patients. MDTs are the key to
individualized treatment in older patients.
⚫ The treatment challenges presented by older patients with CRC make it important
to use some form of GA to inform our clinical decision making.
⚫ The potential for morbidities and the choices if serious complications do occur or
treatments fail, should be discussed in advance.
⚫ Investigators should be encouraged to design not only trials using low-toxicity
treatments that maintain most of the efficacy of full-dose treatments but patient-
centered assessments to expand the evidence base in the treatment of older
patients with CRC.
