Abstract

There are very limited data reported about childhood acute promyelocytic leukemia (APL), especially with arsenic trioxide (As2O3) treatment. We review the clinical course and treatment outcome of 65 children APL. Between January 1999 and December 2005, 65 children (<18 years) with newly diagnosed APL were treated. Three groups of patients were identified according to the different induction regimens. Forty patients were given ATRA alone (group 1, G1), 8 patients were given As2O3 alone (group 2, G2), 15 patients (group 3, G3) were treated with combination of ATRA and As2O3. Two patients received cytosine arabinoside and died at days 2 and 4, respectively. The CR rate of G1 was 95% (38/40). The overall CR rate of G2+G3 was 91.3% (21/23). Toxicity of ATRA and As2O3 were minimal and recoverable during induction. Five children had a hematologic relapse and two developed molecular relapse. Five of them were successfully treated with ATRA alone or combined with As2O3. The 5-year estimate of EFS, DFS and OS between G1 and G2+G3 has no difference. As2O3 is an effective and well tolerable therapy for children with APL and it may be used in those who have dose limiting side effects of ATRA, but also for those with newly diagnosed or relap...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.
