Therapy-related acute leukaemia with mitoxantrone: Four years on, what is the risk and can it be limited?

Abstract: Therapy-related acute leukaemia (TRAL) is a significant concern, when considering treatment with mitoxantrone for multiple sclerosis (MS). We re-evaluated the literature, identifying all case reports and series of > 50 patients reporting TRAL cases in MS. TRAL was diagnosed in 0.73% of the 12,896 patients identified. Median onset was 22 months following treatment. We calculated a number needed to harm of 137.5 exposed patients, significantly higher than our 2008 analysis. We found that 82.8% of patients were e… Show more

“…Three of our patients developed chronic leukemia and four developed acute myeloid leukemia (0.97% of the whole cohort). The literature mostly mentions MITOX therapy‐related acute myeloid leukemia and the incidence found in our study is within the reported range (0.73–0.9%) . The most recorded malignant entity in our study was breast cancer (incidence 1.7%).…”

“…Rationale Post approval of mitoxantrone, new evidence has shown a high risk of cardiomyopathy, ovarian failure, male infertility, chromosomal aberrations, and promyelocytic leukemia [34][35][36][37] associated with mitoxantrone use. Other effective medications with lower risk, which were unavailable at the time of US Food and Drug Administration (FDA) approval of mitoxantrone, are now available for treating MS.…”

“…Although rare, patients on mitoxantrone may experience promyelocytic disorders such as acute myelogenous leukemia [25]. A detailed literature search by Ellis et al concluded that the risk of leukemia increases significantly once the cumulative exposure exceeds 60 mg/m 2 .…”
