We conducted a retrospective study to evaluate the efficacy of combining homoharringtonine (HHT) with all-trans-retinoic acid (ATRA)-based induction therapy, followed by three courses of consolidation chemotherapy and 2-year sequential maintenance therapy in acute promyelocytic leukemia (APL). Fifty-three patients were enrolled in the study. The complete remission (CR) rate was 100?%. No patient died during induction therapy. The 9-year event-free survival (EFS) and 9-year overall survival (OS) for all patients were 79.0 and 83.0?%, respectively. Outcome estimates according to the body mass index (BMI) were carried out. Twenty-three (43.4?%) were underweight/normal (BMI?2), whereas 30 patients (56.6?%) were overweight/obese (BMI?≥?3.0?kg/m2). Underweight/normal-weight patients had a 9-year OS of 100?%, compared with 73.0?% for overweight/obese patients (P?=?0.044). These results indicate that HHT plus ATRA-based induction and consolidation therapy may be a highly efficacious treatment option for newly diagnosed APL. Increased BMI had an adverse prognostic impact in APL.
