assessing frailty
Definition of frailty is crucial in:
Designing Clinical Studies/Trials
Consenting patient
Individualising treatment
Predicting outcome
Comparing series
life expectancy
n./severity of comorbidities
CGA – MGA – screening tools
“rule of thumb”
ASA - POSSUM
Patients’ selection
the Rule of ThumbSurgical assessment was highly
accurate…
lack of consistency
…but not reproducible
Life expectancy tables
consistency in advise to treatmentmean 68.6% (range 30.9% - 91.6%)
Life expectancy tables
Prevalence of comorbidity across the age spectrum
Piccirillo JF. Crit Rev Onc Hem 2008
Comorbidity is prognostically most important in situations where the prognostic impact of the tumour is small.
Comorbidity
Read WL. JCO 2004
Conversely, where the tumour is advanced or aggressive and the prognosis is poor, comorbidity information is less important.
Age & co-morbiditiesare NOT
independent risk factors for operative mortality
• Comorbidities & Functional Status are independent
• Correlation between PS & ADL/IADL is moderate
• Patients with comorbidities do not have a higher risk of developing complications

Surgery:
“If you can do it,it does not mean itneeds to be done”
TME – Total Mesorectal Excision
TME in the elderlyCancer Registry Data: 1,508pt >75yrs
Rutten HJT. Lancet Onc 2008
excessive operative death
Rutten HJT. Lancet Onc 2008
“… the effectiveness of TME surgery in the overall population cannot be simply derived from findings of studies involving a younger age group.”
