Allogeneic Stem Cell Transplantation for Myelodysplastic Syndrome Patients with a 5q Deletion
The deletion (5q) karyotype (del [5q]) in patients with myelodysplastic syndrome (MDS) is the most common karyotypic abnormality in de novo MDS. An increased number of blasts and additional karyotypic abnormalities (del [5q]+) are associated with a poor outcome. We analyzed the outcome of allogeneic hematopoietic cell transplants (HCT) in patients suffering from MDS with only del (5q) or del (5q)+ . A total of 162 patients, of median age 54 years (range, 9 to 73), having MDS and del (5q) abnormalities received HCT from identical siblings (n = 87) or unrelated donors (n = 75). The cumulative incidence of nonrelapse mortality and relapse incidence at 4 years was 29% (95% CI, 22 to 36) and 46%…
Impact of somatic mutations in myelodysplastic patients with isolated partial or total loss of chromosome 7
Monosomy 7 [-7] and/or partial loss of chromosome 7 [del(7q)] are associated with poor and intermediate prognosis, respectively, in myelodysplastic syndromes (MDS), but somatic mutations may also play a key complementary role. We analyzed the impact on the outcomes of deep targeted mutational screening in 280 MDS patients with -7/del(7q) as isolated cytogenetic abnormality (86 with del(7q) and 194 with -7). Patients with del(7q) or -7 had similar demographic and disease-related characteristics. Somatic mutations were detected in 79% (93/117) of patients (82% in -7 and 73% in del(7q) group). Median number of mutations per patient was 2 (range 0-8). There was no difference in mutation frequen…
Comparison of Allogeneic Stem Cell Transplantation for Transformed Acute Myeloid Leukemia Derived from MDS, CMML or MPN. a Report of the Chronic Malignancies Working Party of EBMT
Abstract Introduction Myelodysplastic syndromes (MDS), myeloproliferative neoplasms (MPN) and chronic myelomonocytic leukemia (CMML) can progress to acute myeloid leukemia (transformed AML). The aim of this EBMT registry study was to compare 3 year outcome in patients with transformed AMLwho received allogeneic stem cell transplantation according to the primary disease. Patients and Methods Within the European Society of Blood and Marrow Transplantation (EBMT) registry, we found 4214 patients (female: 39%, male: 61%) with transformed acute myeloid leukemia, who received allogeneic stem cell transplantation between 2000 and 2014. The primary disease was MDS (n=3541), CMML (n=251) or MPN (n=4…
