Validation study reveals improved survival risk stratification in allogeneic transplant recipients, highlighting better pretransplant assessment.

Key Points

To develop and validate a specialized comorbidity index tailored for predicting nonrelapse mortality and survival outcomes in patients undergoing allogeneic hematopoietic cell transplantation.
Retrospective study of clinical and laboratory data from N=1055 patients undergoing allogeneic hematopoietic cell transplantation.
Dataset was randomly split into training and validation sets.
Cox proportional hazards models were used to assign weighted scores to specific comorbidities based on prognostic significance.
The new HCT-specific comorbidity index captured comorbidities in 62% of patients (scores > 0) compared to 12% captured by the Charlson Comorbidity Index.
The new index demonstrated superior predictive accuracy for survival over the Charlson Comorbidity Index, with higher likelihood ratios (23.7 vs 7.1) and higher c-statistics (0.661 vs 0.561, P < .001).
