OBJECTIVE To evaluate factors predictive for relapse in a cohort of adult patients with acute promyelocytic leukemia monitored by molecular methods during consolidation and during at least one month of maintenance therapy. METHODS The charts and laboratory data of 65 adult patients with acute promyelocytic leukemia treated according to the International Consortium on Acute Promyelocytic Leuke...
Leukemia results from the expansion of self-renewing hematopoietic cells that are thought to contain mutations that contribute to disease initiation and progression. Studies of the gene expression profiles of human acute myeloid leukemia samples has allowed their classification based on the presence of translocations and French-American-British subtypes, but it is not yet clear whether their mo...
BACKGROUND The gene for preferentially expressed antigen of melanoma (PRAME) has been shown to be over-expressed in acute promyelocytic leukemia, but its actual incidence and clinical impact are still unknown. DESIGN AND METHODS We studied PRAME expression at diagnosis using real-time quantitative polymerase chain reaction in 125 patients with acute promyelocytic leukemia enrolled in the Span...
Patients with hematologic malignancies are immunosuppressive and may develop cutaneous or invasive infections as a primary sign of immune suppression. Acute promyelocytic leukemia (acute myeloid leukemia M3) is caused by translocation of reciprocal chromosomal rearrangement t(15;17), which produces an oncogenic protein. We herein describe a 71-year-old man having cellulitis with leukocytopenia ...
Therapy-related myelodysplastic syndrome in patients with acute promyelocytic leukemia is a rare event and the prognosis is poor. Allogeneic bone marrow transplantation is recently being reported as an effective treatment. We present a young patient with acute promyelocytic leukemia who developed myelodysplastic syndrome 52 months after complete remission. She underwent allogeneic peripheral bl...
Aplastic anemia (AA) is nowadays considered to be a clonal disorder arising from a defective hematopoietic stem cell developing after a generalized insult to bone marrow. Immunosuppressive treatment (IST) of AA causes suppression of the target dominant population of haematopoietic cells allowing the defective non targeted clones to expand. This may give rise to acute leukemia. Cytogenetic studi...
BACKGROUND Acute promyelocytic leukemia is characterized by a typical reciprocal translocation t(15;17)(q22;q21). Additional chromosomal abnormalities are reported in only 23-43 % of cases of acute promyelocytic leukemia. CASE PRESENTATION Here we report the case of a 46-year-old Syrian Alawis woman with acute promyelocytic leukemia with the typical t(15;17) translocation, but with a second c...
Early mortality in acute promyelocytic leukemia has been reported to occur in less than 10% of patients treated in clinical trials. This study reports the incidence and clinical features of acute promyelocytic leukemia patients treated at Stanford Hospital, CA, USA since March 1997, focusing on early mortality. We show that the risk of early death in acute promyelocytic leukemia patients is hig...
BACKGROUND Acute promyelocytic leukemia is a subtype of acute myeloid leukemia characterized by the t(15;17). The incidence and prognostic significance of additional chromosomal abnormalities in acute promyelocytic leukemia is still a controversial matter. DESIGN AND METHODS Based on cytogenetic data available for 495 patients with acute promyelocytic leukemia enrolled in two consecutive PETH...
