Acute promyelocytic leukemia successfully treated also in elderly patients with significant comorbidities: a 20-year single-center experienc.

ABSTRACT

UNLABELLED Acute promyelocytic leukemia is a unique entity among acute leukemias. Introduction of all-trans retinoic acid and, subsequently, arsenic trioxide in its treatment has markedly improved treatment outcomes for this once frequently fatal disease. Improved outcomes have also been observed in elderly patients, including those in whom standard intensive therapy is contraindicated because of comorbidities.In our center, a total of 60 APL patients were treated in 1993-2013, of whom 9 were aged 60 or more years. Although most of them had significant comorbidities at the time of diagnosis, eight achieved complete remission. At the time of the analysis, six patients were alive and in long-term remission; two patients died of causes other than APL. The median follow-up was 59 months.Included is case report of a patient with a high comorbidity score whose treatment was markedly reduced and individualized.Our experience shows that, in APL patients a curative approach is generally tolerated and should always be attempted regardless of age and comorbidities.
