Relapsed acute lymphoblastic leukemia is the most common cause of cancer-related mortality in young people and new therapeutic strategies are needed to improve outcome. Recent studies have shown that heterozygous inactivating mutations in the histone acetyl transferase, CREBBP, are particularly frequent in relapsed childhood acute lymphoblastic leukemia and associated with a hyperdiploid karyot...

BACKGROUND Although the diagnosis of childhood leukemia is no longer a death sentence, too many patients still die, more with acute myeloid leukemia than with acute lymphoblastic leukemia. The European Union pediatric legislation was introduced to improve pharmaceutical treatment of children, but some question whether the European Medicines Agency (EMA) approach is helping children with leukemi...

The measurement of minimal residual disease (MRD) in pediatric acute lymphoblastic leukemia (ALL) has become the most important prognostic tool of, and the backbone to, upfront risk stratification. While MRD assessment is the standard of care for assessing response and predicting outcomes for pediatric patients with ALL receiving chemotherapy, its use in allogeneic hematopoietic stem cell trans...

BACKGROUND Leukemia is the most prevalent childhood cancer, and Acute Lymphoblastic Leukemia (ALL) constitutes 75% of all cases. Some epidemiological studies have shown a relationship between socioeconomic status (SES) and some childhood cancers. In the present study, an attempt was made to assess socioeconomical status in a case-control study. MATERIALS AND METHODS In 2010, a case-control st...

Acute lymphoblastic leukemia (ALL) is the most common pediatric oncologic diagnosis, and advances in its treatment have led to progressive improvements in survival. The 4 main components of therapy are remission induction, consolidation, maintenance, and central nervous system-directed therapy, and usually last 2 to 3 years. Treatment intensity based on risk-based stratification is the cornerst...

BACKGROUND PI3K/AKT pathway mutations are found in T-cell acute lymphoblastic leukemia, but their overall impact and associations with other genetic aberrations is unknown. PTEN mutations have been proposed as secondary mutations that follow NOTCH1-activating mutations and cause cellular resistance to γ-secretase inhibitors. DESIGN AND METHODS The impact of PTEN, PI3K and AKT aberrations was ...

T-Cell Acute Lym-phoblastic Leukemia In article number 2205854, Jingjing Ye, Min Ji, Chunyan and co-workers observed aberrant adipogenesis in the bone marrow of chemotherapy-treated T-cell acute lymphoblastic leukemia (T-ALL) patients, differentiated-adipocytes attract support residual T-ALL cells. Last, an SREBF1 inhibitor demonstrates superior improvement on therapeutic effect dexamethason by...

The molecular diagnosis of human cancer will hasten the development of treatments tailored to the abnormalities present in each patient's tumor cells. Recent gene expression profiling studies of pediatric acute lymphoblastic leukemia (ALL) suggest that the molecular diagnosis of these diseases is right around the corner.
