Increasing use of allogeneic hematopoietic cell transplantation in patients aged 70 years and older in the United States

In this study, we evaluated trends and outcomes of allogeneic hematopoietic cell transplantation (HCT) in adults ≥70 years with hematologic malignancies across the United States. Adults ≥70 years with a hematologic malignancy undergoing first allogeneic HCT in the United States between 2000 and 2013 and reported to the Center for International Blood and Marrow Transplant Research were eligible. Transplant utilization and transplant outcomes, including overall survival (OS), progression-free survival (PFS), and transplant-related mortality (TRM) were studied. One thousand one hundred and six patients ≥70 years underwent HCT across 103 transplant centers. The number and proportion of allografts performed in this population rose markedly over the past decade, accounting for 0.1% of transplants in 2000 to 3.85% (N = 298) in 2013. Acute myeloid leukemia and myelodysplastic syndromes represented the most common disease indications. Two-year OS and PFS significantly improved over time (OS: 26% [95% confidence interval (CI), 21% to 33%] in 2000-2007 to 39% [95% CI, 35% to 42%] in 2008-2013, P

Therapy related myeloid neoplasm (t-MN) is an emerging challenge in the current era given that newer therapies are improving the life expectancy of patients diagnosed with cancer. This condition arises as a result of exposure to prior chemotherapy or radiotherapy used to treat malignant or non-malignant conditions. The World Health Organization (WHO) 2001 classification of tumors of hematopoietic and lymphoid tissues had initially described this disorder with two subtypes – therapy related acute myeloid leukemia (t-AML) and therapy related myelodysplastic syndrome (t-MDS) 1.

Application of next-generation sequencing (NGS) panels is usually limited to diagnosis, prognosis, and development of personalized treatment strategies/targeted therapies for patients with myeloid malignancies e.g., Myelodysplastic syndrome (MDS), myeloproliferative neoplasms (MPN), and acute myelogenous leukemia (AML). Here we present a case of 3 year old male that presented with pancytopenia and splenomegaly. His initial bone marrow revealed mild to moderate fibrosis (normocellular; no increase in blasts).

We report a myelodysplastic syndrome (MDS) patient who presented Fusarium solani infection associated with granulocytic sarcoma as an initial presentation of acute myeloid leukemia (AML) transformation. We performed histological examination, immunohistochemistry analysis, culture of the biopsy tissue and DNA sequencing to make a conclusive diagnosis of F. solani and granulocytic sarcoma, reinforcing the necessity of performing complete evaluation of skin lesions in immunocompromised patients.

Myelodysplastic syndrome (MDS) is rare in the pediatric age group and it may be associated with inheritable bone marrow failure (BMF) such as Fanconi anemia (FA). FA is a rare multi-system genetic disorder, ch...

We present a 2-year-old boy with splenomegaly, leukocytosis, thrombocytopenia, anemia, and excess myeloblasts with easily seen Auer rods, and marked dysgranulopoiesis and dyserythropoiesis. Conventional cytogenetic analysis showed a sole abnormality of t(3;5)(q25;q35). Microarray analysis showed a terminal 21 Mb region of copy-neutral loss of heterozygosity on 19q. Disease-related somatic NRAS mutation was detected. This case represents an unusual JMML with Auer rods and marked myelodysplasia. These unusual histopathologic features may be related to the t(3;5)(q25;q35). A t(3;5) with variable breakpoints has been reported ...

Juvenile myelomonocytic leukemia (JMML) is an aggressive myeloproliferative neoplasm occurring in young children. The common denominator of these malignant myeloid disorders is the limited benefit of conventional chemotherapy and a particular resp...

AbelAbstractThe myelodysplastic syndromes (MDS) are a varied group of hematologic neoplasms that lead to bone marrow failure, and also carry a risk of progression to acute myeloid leukemia. Patients with MDS suffer significant impairments to both their quality of life and survival. Age is the dominant risk factor for the development of MDS, with a median age at diagnosis over 70 years. Consequently, patients with MDS frequently have concurrent comorbidities and/or frailty which may be coincident ...

We report a case of myeloid sarcoma with megakaryoblastic differentiation in the breast of a patient with history of essential thrombocythemia. The mass was composed of undifferentiated pleomorphic malignant cells in trabecular cords and nests with many scattered giant malignant cells and brisk abnormal mitoses. On immunohistochemistry, the neoplastic cells were positive for CD61, CD31, CD34, Factor VIII and CD43 which confirmed the diagnosis. To our knowledge, this is the first report of myeloid sarcoma with megakaryoblastic morphology occurring in the breast. Here we discuss the clinicopathologic features of this rare en...
