No difference in toxicity and TRM in comparison to younger population of patients

Conclusions:

 Is age per se a negative prognostic factor?

 Age has a negative impact on prognosis mainly because

 Referral bias

 Under-treatment

 And should age impact on treatment decision?

 We need a better risk stratification in older patients based on:

 Comorbidity

 Performance status

 Social support

 Not on age

Factors Determining Outcome after HCT

• Stage of Malignant Disease

• Functional Performance Status

• Other CoMorbid Conditions

CoMorbid Conditions at HCT

Figure 3. Kaplan-Meier probabilities of survival among patients with hematologic malignancies treated with allo-NMA-HCT as stratified into four risk groups based on a consolidated HCT-CI and KPS scale. Group

I (solid black line) includes patients with HCT-CI scores of 0 to 2 and a

KPS of 80%; group II (dotted black line) includes patients with

HCT-CI scores of 0 to 2 and a KPS of 80%; group III (solid blue line) includes patients with HCT-CI scores of 3 and a KPS of 80%; group

IV (dotted blue line) includes patients with HCT-CI scores of 3 and a

KPS of 80%. Survival rates at 2 years were 68%, 58%, 41%, 32% for risk groups I, II, III, and IV, respectively. (From Sorror et al., 2008.45

Conclusions

1. Older age (60-75 yrs), per se, is not a risk factor for adverse outcome following NMA allogeneic HCT

2. Among older allograft recipients, overall survival is decreased with:

 High-Risk Malignancy (HR2.22)

 HCT-CI

Cost of Chronic Transfusion for Stroke Prevention in SCD

Data were collected on 21 patients for 296 patient months

Charges ranged from $9828 to $50,852 per patient per year

Charges for patients who required chelation therapy ranged from $31,143 to $50,852 per patient per year (median, $38 607)

Charges are approx. $400 000 per patient decade for patients who require deferoxamine chelation
