5 Background Comorbidities = prognosis factor for cancer Consequences on patient s clinical pathway diagnosis ----> treatment Ex : - severe COPD limitation to thoracic surgery - severe congestive heart failure limitation to the use of some cytotoxic drugs 5

6 Clinical pathway Ambulatory care Evaluation Treatment Follow up End of life Process Screening Specialists Treatments Consultations Procedures Terminal care Result Detection Stage of disease Response Toxicity Relapse Controlled disease Survival without progression Death Death du to intercurrent event 6

7 Comorbidities and cancer Are there good tools for comorbidities assessment? 7

8 Charlson comorbidity index, CCI Charlson ME, et al : J Chron Dis 1987;40:5, diseases with weight from 1 to 6, prédictive of death +++ Comorbidity Score Myocardial infarction Congestive heart failure 1 1 Arteritis (peripheral vascular) 1 Cerebral diseases (except hemiplegia) 1 Dementia 1 Chronic obstructive pulmonary diseases 1 Systemic diseases 1 Gastro-duodenal ulcer 1 Hepatic failure (mild) 1 Diabetes mellitus without complication 1 Diabetes mellitus with another involved organ 2 Hemiplegia 2 Renal failure (moderate to severe) 2 Other solid tumors without metastasis 2 Leucemia 2 Lymphoma or Myeloma 2 Hepatic failure (moderate to severe) 3 VIH infection 6 TOTAL 8

11 Charlson s age comorbidity index Age-Comorbidity score Estimated relative risk (1.25, 1.68) 2.10 (1.57, 2.81) 3.04 (1.96, 4.71) 4.40 (2.45, 7.90) 6.38 (3.07, 13.24) 9.23 (3.84, 22.20) (4.81, 37.22) (6.01, 62.40) 11

12 Charlson s age comorbidity index Overall survival for patients >75 according to CCI Comorbidity score : > 4 12

13 EVALUATION Other index : adult comorbidity evaluation 27 (27 conditions) Simplified comorbidity score SCS: Colinet et al. Br J Cancer 2005;93: Tabacco (7), diabetes mellitus (5), Renal failure (4), Resp diseases, cancer, heart failure, alcoholism (1) 13

14 Adult comorbidity evaluation 27 Read, JCO 2004;22: cancers. Adult index 27 Prognosis according to severity Lung colon prostate breast Relationship to stage but important variable for analysis 14

15 Adult comorbidity evaluation 27 Impact of comorbidities according to cancer type 15

16 Comorbidity scores Other index : adult comorbidity evaluation 27 (27 conditions) Simplified comorbidity score SCS: Colinet et al. Br J Cancer 2005;93: Tobacco (7), diabetes mellitus (5), renal failure (4), Resp diseases, cancer, heart failure, alcoholism (1) 16

17 Simplified comorbidity score SCS: Colinet et al. Br J Cancer 2005;93: Comorbidity Tobacco consumption Diabetes mellitus Renal insufficiency Respiratory comorbidity Cardiovascular comorbidity Neoplastic comorbidity Alcoholism Weighting

18 Simplified comorbidity score SCS: Colinet et al. Br J Cancer 2005;93: P<0,01 18

19 Comorbidity tools weaknesses : - hypothesis : each item has the same accuracy for any disease - some items refer to the studied disease (eg : cancer, weight loss, anemia, ) 19

25 Impact of comorbidities in elderly patients 1255 patients, with 481 patients in the ACT trial and 774 patients in the ANSCLC trial Median age: 61.2 years ( ); 428 patients were 65 years 391 (31%): other medical conditions (besides NSCLC) 310 (25%): CCI score of 1, 81 (6%) CCI score of 2 or higher Comorbidity rates were higher in : older patients, male, squamous histology Comorbidity rates were lower in : Patients with weight loss 5% (31% vs 37%, p = 0.04) Patients with time from diagnosis to randomization < 6 months (p=0.004) Asmis, PAsco 2006,abstr

26 Impact of comorbidities in elderly patients Dose intensity Age and comorbidity were associated with lower total dose in the ANSCLC trial while only age predicted for a lower total dose in the ACT trial Toxicity (univariate analysis) * Comorbidities associated with more grade 3-5 infection (p=0.03) and GI toxicity (p=0.022), pain (p=0.01), nausea (p=0.04) * Age 65 was associated with grade 3-5 neurologic toxicity (p<0.0001), GI toxicity (p=0.03), fatigue (p=0.01) Asmis, PAsco 2006,abstr

29 Impact of comorbidities in elderly patients Comorbidity is common in patients with NSCLC, and occurs in 42% of patients over the age of 65 Males, in general, had more comorbidity than females (35% vs 21%, p<0.0001) While the elderly received less chemotherapy, they derive the same benefit as younger patients in terms of overall survival and they should not be excluded from clinical trials. However, the presence of comorbidity is associated with a poorer outcome. Asmis, PAsco 2006,abstr

47 DISCUSSION 47

48 Group 1 : independant patient - No severe cardiac or pulmonary comorbidity (grade >2) - No untreated comorbidity - ADL > 4/6 et IADL > 4/6 - Age < 80 - Weight loss <15 % of body weight -Clocktest = 2/2 - No fall within the last 3 months - Creatinin clearance > 50 ml/min 48

49 Group 2 : vulnerable patient - 1 or 2 not controlled or not treated comorbidities - ADL < 4/6 or IADL< 4/6 - Age > 80 - Fall within the last 3 months - Positive depression test - Weight loss between % of body weight - Creatinin clearance < 50 ml /min -Clocktest <2 49

50 Group 3: frailed and dependant patients - More than 2 comorbidities not controlled or not treated -ADL < 4 - IADL abnormal on 3 evaluable items or more - Weight loss >35 % of body weight - Creatinin clearance< 30 ml/min 50

51 Comorbidities and cancer Patient s refusal Or non proposition of treatment Interest of observational studies according to non diagnosed or non recorded diseases (dementia) 51

52 Conclusion Comorbidities: major item for cancer Clinical pathway: comorbidities have major impact on management Severity is a very important dimension Major role for elderly 52

53 Conclusion Future : Patient: center of strategy management Geriatric oncology associated with multi disciplinary staff Clinical research with social dimension 53
