Thoracic Oncology & EA3279 Marseille - France Why considering QoL in lung cancer? Activity: –Response rate –Response duration Safety Profile Efficacy –Symptoms –Survival Quantitative assessment
5
However … –Under-evaluation of symptoms by MD (time-consuming, lack of standardization) –Some effects are known by the patient only (ex. pain) –Assessment of treatment by the patient itself is a unique point of view (ex. spirometry / dyspnea) Why considering QoL in lung cancer? Thoracic Oncology & EA3279 Marseille - France

Symptoms in lung cancer patients Why considering QoL in lung cancer? Thoracic Oncology & EA3279 Marseille - France
7
Thus, patients’ point of view regarding treatments’ outcomes is a potential indicator of efficacy … –Promoters & investigators (clinical trials) –State agencies (EMEA, FDA) –Clinicians (daily practice) Why considering QoL in lung cancer? Thoracic Oncology & EA3279 Marseille - France

‘Modern’ qualitative assessment: –By the patient on its health: Quality of life –By the patient on its care: Satisfaction Why considering QoL in lung cancer? Thoracic Oncology & EA3279 Marseille - France

17
Review phIII RCTs (2003+) –14 trials (6665 pts), 13 with validated instruments –EORTC QLQ C30 –QoL primary end-point, n=2 –9 trials of acceptable quality (>50% surviving pts being complaint at baseline + 1 at least one point) –Only one showing significant difference Tanvetyanon et al, J Thorac Oncol 2007 Thoracic Oncology & EA3279 Marseille - France QoL in thoracic oncology trials?
18
Review RCTs (<2003) –29 trials (8445 pts), 20 with validated instruments –EORTC QLQ C30 –QoL primary end-point, n=6 –Some difference in HRQOL in 15 trials (68%) –Results presented adequately in 17 cases (59%) –Management missing data in 18 trials (62%) Bottomley et al, J Clin Oncol 2003 Thoracic Oncology & EA3279 Marseille - France QoL in thoracic oncology trials?
19
Relationship with standard efficacy measures –EORTC 08975 –N=391 –EORTC C30 +LC13 Efficace et al, Ann Oncol 2006 Thoracic Oncology & EA3279 Marseille - France A new field for QoL?
20
Relationship with standard efficacy measures Thoracic Oncology & EA3279 Marseille - France De Marinis et al, J Thorac Oncol 2008 A new field for QoL?
21
Thoracic Oncology & EA3279 Marseille - France Gralla et al, J Thorac Oncol 2008 In summary, a complex interplay! If a treatment fails to control the disease, it is unlikely to improve QoL even if less toxic or more convenient … Patients who respond to treatment experience better symptom relief than those who progress, … And those with higher QoL at baseline have better survival than those with lower QoL.

QoL in daily practice? Bezjack et al, QoL Research 2001 Thoracic Oncology & EA3279 Marseille - France Agree % Disagree % QoL is a subjective concept that cannot be quantified 1486 Using published QoL information is essential to good care in pts with cancer 8218 I often do not have the time required to discuss QoL with my patients 2773 I rely on my clinical experience to assess QoL 7723

Conclusions Assessment of treatments … –< 80’s: Clinic, biology, radiology –90’s: CT-scan –00’s: TEP-FDG, genes, … –10’s: QoL! Improve quantitative & add qualitative assessments Thoracic Oncology & EA3279 Marseille - France
41
Conclusions QoL measures should be done as rigorously as clinical, radiological, biological assessments. Standardization, standardization, standardization … Let’s discuss! Thoracic Oncology & EA3279 Marseille - France
