Therapy-related myelodysplastic syndrome after successful treatment of acute promyelocytic leukemia: case report and literature review

Abstract

In the 2016 revision of the World Health Organization classification the term therapy-related myeloid neoplasia (t-MN) defines a subgroup of acute myeloid leukemia (AML) comprising patients who develop myelodysplastic syndrome (MDS-t) or acute myeloid leukemia (AML-t) after treatment with cytotoxic and/or radiation therapy for various malignancies or autoimmune disorders. We report the case of a 36 year old patient with t-MN (t-MDS) after achieving complete remission (CR) of a PML-RARA positive acute promyelocytic leukemia (APL) at 32 months after diagnosis. Initially classified as low risk APL and treated according to the AIDA protocol - induction and 3 consolidation cycles - the patient achieved a complete molecular response in September 2013 and started maintenance therapy. On follow-up PML-RARA transcript remained negative. In January 2016 leukopenia and thrombocytopenia developed and a peripheral blood smear revealed hypogranular and agranular neutrophils. Immunophenotyping in the bone marrow aspirate identified undifferentiated blast cells that did not express cytoplasmic myeloperoxidase. The cytogenetic study showed normal karyotype. The molecular biology tests not identified PMLRARA transcript. A diagnosis of t-MDS (AREB-2 - WHO 2008) was established. Treatment of AML was started with 2 “3+7” regimens and 1 MEC cycle. Two months from diagnosis, while in CR, an allogeneic HSCT from an unrelated HLA compatible donor was performed after myeloablative regimen. An unfavorable clinical evolution was followed by death on day 9 after transplantation. The occurrence of t-MNs during CR of APL represents a particular problem in terms of follow-up and differential diagnosis of relapse and constitutes a dramatic complication for a disease with a favorable prognosis.

Myelodysplastic syndrome with myelofibrosis in a 12-year-old patient – A case report

Abstract

Myelodysplastic syndromes are a heterogeneous group of clonal disorders characterized by peripheral blood cytopenia and normal or hypercellular bone marrow with dysplasia in more than one blood cell lineage, unfavorable prognosis, and lack of response to treatment. We present the case of a 12-year-old male patient who was referred to the Hematology and Oncology Department of Pediatric Clinic I Târgu- Mures in May 2016, with splenomegaly and pancytopenia. The osteomedullary biopsy revealed myelofibrosis, discrete dysplasia of the myeloid series and megakaryocytes, blasts CD34+ approximately 10%, which led to the diagnosis of myelodysplastic syndrome with myelofibrosis. The myeloid precursors indicated a high risk of transformation into acute myeloid leukemia, so chemotherapy associated with corticosteroids was started, leading to slight improvements. Although myelodysplastic syndrome associated with myelofibrosis is rare at this age, despite the treatment and favorable progression in the case presented, in the absence of hematopoietic stem cell transplantation the prognosis remains unfavorable.
