Biologic vs physiologic age in the transplant candidate.

Area of Science:

• Geriatric Medicine
• Hematology
• Oncology

Background:

• Hematopoietic cell transplantation (HCT) is a vital treatment for hematologic malignancies.
• Increasingly, older adults are undergoing HCT, but transplant-related risks remain a concern.
• Traditional age metrics do not fully capture fitness for HCT in elderly patients.

Purpose of the Study:

• To evaluate the role of geriatric assessment (GA) in assessing older adults for HCT.
• To determine if GA can identify vulnerabilities impacting transplant outcomes.
• To explore how GA can inform HCT candidacy and improve survival predictions.

Main Methods:

• Geriatric assessment (GA) was employed to systematically evaluate older transplant candidates.
• GA included assessments of comorbidity, functional status, nutrition, and social support.
• Physiologic age was characterized through comprehensive health-related domain measures.

Main Results:

• A high prevalence of vulnerabilities was identified in older allogeneic transplant patients via GA.
• Significant comorbidity or functional limitations were linked to increased transplant-related mortality.
• GA provides a better measure of physiologic age than chronologic or biologic age alone.

Conclusions:

• Incorporating physiologic age through GA can refine estimates of life expectancy and survival post-HCT.
• GA is crucial for informing HCT candidacy decisions in older populations.
• Further research is needed to optimize GA tools and interventions for transplant patients.
