Abstract
Association between comorbidity burden and patient outcomes has not been adequately investigated in acute promyelocytic leukemia (APL). We utilized the National Cancer Database to evaluate the association of the Charlson–Deyo Comorbidity Index (CCI) with one-month mortality and overall survival (OS) in adults ≥60 years with APL. One-month mortality was 16%, 24%, and 32%, and 3-year OS was 61%, 53%, and 38% for patients with CCI 0, 1, and ≥2, respectively. One-month mortality was higher for patients with CCI 1 (OR 1.67, 95% CI 1.29–2.16, p < .001) and CCI ≥ 2 (OR 2.31, 95% CI 1.70–3.13, p < .001) compared to patients with CCI 0. Patients with CCI 1 (HR 1.27, 95% CI 1.10–1.46, p < .001) and CCI ≥ 2 (HR 1.74, 95% CI 1.48–2.06, p < .001) had worse OS compared to patients with CCI 0. In conclusion, CCI is an independent predictor of survival outcomes in patients with APL.
