Paediatric B-cell precursor acute lymphoblastic leukaemia (BCP-ALL) is the most common cancer of childhood, yet little is known about BCP-ALL predisposition. In this study, in 2,187 cases of European ancestry and 5,543 controls, we discover and replicate a locus indexed by rs77728904 at 9p21.3 associated with BCP-ALL susceptibility (Pcombined=3.32 × 10(-15), OR=1.72) and independent from rs3731217, the previously reported ALL-associated variant in this region. Of correlated SNPs tagged by this locus, only rs662463 is significant in African Americans, suggesting it is a plausible causative variant. Functional analysis shows that rs662463 is a cis-eQTL for CDKN2B, with the risk allele associated with lower expression, and suggests that rs662463 influences BCP-ALL risk by regulating CDKN2B expression through CEBPB signalling. Functional analysis of rs3731217 suggests it is associated with BCP-ALL by acting within a splicing regulatory element determining CDKN2A exon 3 usage (P=0.01). These findings provide new insights into the critical role of the CDKN2 locus in BCP-ALL aetiology.

Post-transplant lymphoproliferative disorder is a rare and serious complication of organ and stem cell transplant secondary to immunosuppressive therapies, most commonly of monomorphic B-cell subtype. Here we describe the first reported case of a pediatric heart transplant patient who developed both monomorphic B-cell and nondestructive PTLD with plasmacytic hyperplasia followed by an unrelated case of monomorphic T-cell and nondestructive PTLD with plasmacytic hyperplasia, which later relapsed. We detail the patient's risk factors for development of PTLD and her successful treatment regimens.

Anterior segment infiltration as the sole manifestation of relapse is exceptionally uncommon and may mimic noninfectious uveitis, leading to diagnostic delay. We report the case of a 4-year-old boy with a history of B-cell precursor ALL, diagnosed at age 2 and treated according to the ALL IC BFM 2009 protocol.

Background And Objectives: Neuroimaging findings in immune effector cell-associated neurotoxicity syndrome (ICANS) have not been systematically described. We created the chimeric antigen receptor (CAR) T-cell Neurotoxicity Imaging Virtual Archive Library (CARNIVAL), a centralized imaging database for children and young adults receiving CAR T-cell therapy. Objectives of this study were to (1) characterize neuroimaging findings associated with ICANS and (2) determine whether specific ICANS-related neuroimaging findings are associated with individual neurologic symptoms.

Large B cell lymphomas (LBCL) are clinically and biologically heterogeneous lymphoid malignancies with complex microenvironments that are central to disease etiology. Here, we have employed single-nucleus multiome profiling of 232 tumor and control biopsies to characterize diverse cell types and subsets that are present in LBCL tumors, effectively capturing the lymphoid, myeloid, and non-hematopoietic cell compartments. Cell subsets co-occurred in stereotypical lymphoma microenvironment archetype profiles (LymphoMAPs) defined by; (1) a sparsity of T cells and high frequencies of cancer-associated fibroblasts and tumor-associated macrophages (FMAC); (2) lymph node architectural cell types with naive and memory T cells (LN); or (3) activated macrophages and exhausted CD8 T cells (TEX).
