Abstract

We analyzed the incidence, risk factors, and outcome of therapy-related myeloid neoplasms (t-MNs) in patients with acute promyelocytic leukemia (APL) in first complete remission (CR). From 1996 to 2008, 1,025 patients with APL were enrolled onto three sequential trials (LPA96, LPA99, and LPA2005) of the Programa Español para el Tratamiento de Enfermedades Hematológicas and received induction and consolidation therapy with all-trans-retinoic acid (ATRA) and anthracycline-based chemotherapy. Seventeen of 918 patients who achieved CR developed t-MN (10 with < 20% and seven with > or = 20% of bone marrow blasts) after a median of 43 months from CR. Partial and complete deletions of chromosomes 5 and 7 (nine patients) and 11q23 rearrangements (three patients) were the most common cytogenetic abnormalities. Overall, the 6-year cumulative incidence of t-MN was 2.2%, whereas in low-, intermediate-, and high-risk patients, the 6-year incidence was 5.2%, 2.1%, and 0%, respectively. Multivariate analysis identified age more than 35 years and lower relapse risk score as independent prognostic factors for t-MN. The median overall survival time after t-MN was 10 months. t-MN is a relatively infrequent, long-term, and severe complication afte...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
