CD8+ T cells are an important weapon in the therapeutic armamentarium against cancer. While CD8+CD103+ T cells with a tissue-resident memory T (TRM) cell phenotype are associated with favorable prognoses, the tumor microenvironment also contains dysfunctional exhausted T (TEX) cells that exhibit a variety of TRM-like features.
Acute lymphoblastic leukaemia (ALL) is the most common paediatric malignancy and remains one of the most common causes of cancer-related death in children and adolescents. It is characterised by the proliferation of immature lymphoid cells capable of infiltrating bone marrow, blood and extramedullary sites. Five-year overall survival rates exceed 90% with current multidrug chemotherapeutic regimens. This manuscript reviews the abdominal imaging features of leukaemic infiltration in children with ALL at the time of initial diagnosis and following relapse.
Ewing Sarcoma of the pelvis has poorer outcomes than other anatomical sites, with complex anatomy often precluding resection with wide margins. The role of postoperative radiotherapy (RT) in improving outcomes remains undefined. A systematic review using Medline, Embase and Cochrane databases (1972-April 2024) evaluated postoperative RT's impact on local recurrence, event-free survival and overall survival. Twenty-nine retrospective studies (21 to 296 patients) met inclusion criteria, with 28 rated good quality.
Acute lymphoblastic leukaemia is a highly heterogeneous malignancy characterised by various genomic alterations that influence disease progression and therapeutic outcomes. Gene fusions involving the immunoglobulin heavy chain gene represent a complex and diverse category.
In pediatric cancer precision medicine clinical trials settings, parents proactively seeking treatment and answers to causation may request return of their child's raw data and/or biospecimen. To satisfy such requests, the ZERO Childhood Cancer Program required a guidance document.

Many mechanisms underlying an effective immunotherapy-induced antitumour response are transient and critically time dependent. This is equally true for several immunological events in the tumour microenvironment induced by other cancer treatments. Immune checkpoint therapy (ICT) has proven to be very effective in the treatment of some cancers, but unfortunately, with many cancer types, most patients do not experience a benefit.
Hematopoietic cell transplantation (HCT) is an effective treatment for pediatric patients with high-risk, refractory, or relapsed acute myeloid leukemia (AML). However, a large proportion of transplanted patients eventually die due to relapse. To improve overall survival, we propose a combined strategy based on cord blood (CB)-HCT with the application of AML-specific T cell receptor (TCR)-engineered T cell therapy derived from the same CB graft.
Acute lymphoblastic leukemia expressing the gamma delta T-cell receptor (γδ T-ALL) is a poorly understood disease. We studied 200 children with γδ T-ALL from 13 clinical study groups to understand the clinical and genetic features of this disease. We found age and genetic drivers were significantly associated with outcome.
Peers play a crucial role in supporting wellbeing and psychosocial development for young people aged 12-25. However, a cancer experience often leads to challenges maintaining friendships. There have been no prior attempts to map or synthesise available research or resources on support specifically from friends for young people with cancer, limiting the capacity to draw conclusions or determine next steps for how to best support young people with cancer. This review aims to address this gap by mapping and synthesising the available literature and resources.
