What is the final goal ?
• Better treat patients
– Ensure tumor control, as much as possible
– Limit the risk of adverse events
• which may lead to dependencies or even death
• Maintain quality of life
– Patient is still leaving at home
– Still autonomous with no sequellae
– Cancer is controlled (cured ?)
How to screen patients
to design treatment
with appropriate efficacy / toxicity ratio ?
5
Available data for screening
• Standard evaluation– Performance status
• At baseline
• A few months before
– Organ function• Creatinine clearance
• Liver tests…
– Nutritional status• Weight, albumin…
• Geriatric assessment– Designed for the oldest
– To be implemented in oncology
6
How many Risk Groups ?
• Heterogeneous population
• Three groups (or even more)
– Fit
– Intermediate
– Frail
How to design screening tools ?
• Various solutions– Identify a specific vulnerable profile
• Vulnerable geriatric profile
– Questionnaires, Fried criteria
• Non feasibility of a specific treatment
– Or Identify predictors of unacceptable events
• Early death, functional decline, toxicity
Balducci’s conceptApproach for a phenotype
• >70 and at least one factor
– > 80
– ≥3 comorbidities grade 3
– At least one comorbidity grade 4
– Dependent for at least one activity (ADL)
– At least one geriatric syndrome
S Monfardini, Ann Oncol 2005; 16: 1352-8

• >70 and at least one factor– > 80
– comorbidities grade 3 - 4
– Dependent for at least one activity (ADL)
– At least one geriatric syndrome

Oncologists’ approachFeasibility of chemotherapy
• >70 and at least one factor
– Poor performance status (WHO 3-4)
– Cardiac contra-indication to doxorubicin
– Low creatinine clearance (<50 ml/mn)
– Neutropenia or thrombocytopenia
– Severe comorbidities
Soubeyran P, J Ger Oncol 2011;2:36-44
Characteristics of the patients
Aggressive lymphomas
• Italian Group
– Median age 83 (70-96)
– Geriatric assessment
• >80: 73%
• Dependent : 56%
• Severe comorb.: 43%
– aaIPI 2-3 56.7%
• PS 2-4 60%
• Stage III-IV 56.6%
• Abnormal LDH 46.7%
• EORTC Group
– Median age 78.5 (70-92)
– Geriatric assessment
• >80: 34.3%
• Dependent : 53%
• Severe comorb.: 18.7%
– aaIPI 2-3 72%
• PS 2-4 69%
• Stage III-IV 50%
• Abnormal LDH 66%
Limits of these classifications
• Designed by physicians empirically
• Significant risk to be wrong
– Patient classified in the wrong category
– Because of thresholds…
Another approachPredictors of unacceptable events
• Events which would have changed your initial
decision, would you have known it may occur later…
– Early death
– Functional decline
– Hospitalization for toxicity
– Early death
– Functional decline
– Hospitalization for toxicity

How to decide?
Adverse events to avoidControl the disease
Life expectancy
Too many patients to evaluate
Need for Screening tools

are useful

Conclusion
• CAUTION
– Screening is not geriatric assessment
– Thresholds are not the reality of daily life
• All these tools are made to HELP the
oncologist take the right decision
• Not to replace him in the decision process
– Still physicians
– With many different patients
