Published: November 2021

T-cell acute lymphoblastic leukemia (T-ALL) is an uncommon, yet aggressive leukemia that accounts for approximately one-fourth of acute lymphoblastic leukemia (ALL) cases. / and are the most common mutated genes in T-ALL. Children and young adults are treated with pediatric intensive regimens and have superior outcomes compared to older adults. In children and young adults, Nelarabine added to frontline chemotherapy improves outcomes and end of consolidation measurable residual disease has emerged as the most valuable prognostic marker. While outcomes for de-novo disease are steadily improving, patients with relapsed and refractory T-ALL fare poorly. Newer targeted therapies are being studied in large clinical trials and have the potential to further improve outcomes. The role of allogeneic stem cell transplant (HSCT) is evolving due to the increased use of pediatric-inspired regimens and MRD monitoring. In this review we will discuss the biology, treatment, and outcomes in pediatric and adult T-ALL.

The homeodomain protein homeobox (HOPX), a multifaceted regulator of cellular functions and developmental processes, is predominantly expressed in stem cells across diverse tissues; it has also emerged as a tumour suppressor in various solid cancers. However, its role in haematological malignancies still remains undefined. This study aimed to elucidate its significance in T-cell acute lymphoblastic leukaemia (T-ALL).

BACKGROUND Fibrosing mediastinitis (FM) is a rare, fibroproliferative disorder within the mediastinum. It is extremely rare for hematologic malignancies to develop as FM. CASE REPORT A 32-year-old Japanese man with a 1-month history of headache and 2-week history of facial swelling underwent chest computed tomography (CT); a diffuse mass-like lesion was revealed in the anterior mediastinum with severe stenosis of vital mediastinal organs.

Extreme hyperleukocytosis (Leukocyte count >200 × 10/L) in an adolescent young adult (AYA) patient with B-ALL could result in mild symptoms of leukostasis. Hyperleukocytosis requires prompt initiation of therapy with adequate hydration, cytoreduction and prevention of tumor lysis. Ph + B-ALL may present with extreme hyperleukocytosis and may be resistant to initial pre-phase therapy.

Background: Methotrexate is an important component of curative therapy in childhood acute lymphoblastic leukemia (ALL), but the role of genetic variation influencing methotrexate clearance and transport in toxicity susceptibility in children with ALL is not well established. Therefore, we evaluated the association between suspected methotrexate pharmacogenomic variants and methotrexate-related neurotoxicity.

Methods: This study included children (aged 2-20 years) diagnosed with ALL (2005-2019) at six treatment centers in the southwest United States.

Objective: Of this study was to analyse the correlation of gene polymorphisms with clinical and laboratory data of paediatric patients with B-lineage acute lymphoblastic leukaemia with prognostically unfavourable features.

Methods: A study of 200 children with B-lineage acute lymphoblastic leukaemia (B-ALL) treated with polychemotherapy programmes was conducted. Analysis by sex revealed a statistically insignificant predominance of the group of boys over girls (54%).
