Summary: Multiple myeloma (MM) primarily affects older patients. There are scarce data on the outcomes of young adults undergoing autologous transplantation (auto‐HCT). In this single‐centre analysis, we included 117 younger patients, with a median age of 37 years (range 22–40) at transplant. Seventeen (15%) patients had high‐risk cytogenetics. Before transplant, 10% of patients achieved ≥CR and 44% achieved ≥VGPR. At best post‐transplant response, 56% and 77% of patients achieved ≥CR and ≥VGPR respectively. With a median follow‐up for survivors of 72.6 months (range 0.9–238.0), median PFS and OS were 43.1 months (95% CI 31.2–65.0) and 146.6 months (95% CI 100.0–208.1) respectively. Patients who underwent auto‐HCT after 2010 had better median PFS (84.9 months vs. 28.2 months, p < 0.001) and OS (NR vs. 91.8 months, p < 0.001) compared with those transplanted earlier. In multi‐variate analysis, achieving ≥CR as best post‐transplant response was associated with improved PFS (HR [95% CI] 0.55 [0.32–0.95], p = 0.032), while achieving ≥VGPR was predictive of superior OS (0.32 [0.16–0.62], p < 0.001). Three patients (3%) developed a second primary malignancy. Younger MM patients had durable survival after auto‐HCT, which further improved after the availability of novel anti‐myeloma drugs in recent years. Depth of response following transplant remains a key predictor of survival. [ABSTRACT FROM AUTHOR]

Chimeric antigen receptor T-cell (CAR T) therapy is a revolutionary treatment for pediatric, adolescent and young adult patients (AYA) with relapsed/refractory B-cell acute lymphoblastic leukemia. While the landscape of immunotherapy continues to rapidly evolve, widespread use of CAR T therapy is limited and many questions remain regarding the durability of CAR T therapy, methods to avoid CAR T therapy resistance and the role of consolidative stem cell transplant. Modified strategies to develop effective and persistent CAR T cells at lower costs and decreased toxicities are warranted. In this review we present current indications, limitations and future directions of CAR T therapy for ALL in the pediatric and AYA population. [ABSTRACT FROM AUTHOR]

The Cornell Assessment for Pediatric Delirium (CAPD) was first proposed by the Pediatric Acute Lung Injury and Sepsis Investigators Network-Stem Cell Transplantation and Cancer Immunotherapy Subgroup and MD Anderson CARTOX joint working committees, for detection of immune effector cell associated neurotoxicity (ICANS) in pediatric patients receiving chimeric antigen receptor (CAR) T-cell therapy. It was subsequently adopted by the American Society for Transplantation and Cellular Therapy. The utility of CAPD as a screening tool for early diagnosis of ICANS has not been fully characterized. We conducted a retrospective study of pediatric and young adult patients (n=15) receiving standard-of-care CAR T-cell products. Cytokine release syndrome (CRS) and ICANS occurred in 87% and 40% of patients, respectively. ICANS was associated with significantly higher peaks of serum ferritin. A change in CAPD from a prior baseline was noted in 60% of patients with ICANS, 24–72 h prior to diagnosis of ICANS. The median change from baseline to maximum CAPD score of patients who developed ICANS versus those who did not was 13 versus 3, respectively (p=0.0004). Changes in CAPD score from baseline may be the earliest indicator of ICANS among pediatric and young adult patients which may warrant closer monitoring, with more frequent CAPD assessments.

Patients undergoing chemotherapy and especially hematopoietic stem cell transplantation (HSCT) require frequent transfusions, and thus, transfusion reaction (TR) vigilance is critical in this population. The reported incidence of TRs across all patients is 2%, and pediatric patients may experience 2-2.6 times more reactions than adults. However, the TR profile may differ in the immunocompromised population. There is a paucity of data in this area, as pediatric oncology and HSCT patients are often excluded from TR studies. Our goals were to assess the prevalence and describe TRs among immunocompromised pediatric patients and to improve recognition of TRs across this population. Pediatric clinical providers completed a TR training module in May – June, 2019. A single-institution retrospective review was conducted. All TRs in patients aged less than 25 years were reviewed over a 3-month period from July 1, 2019 to October 1, 2019. Over a 3-month period, 1,786 transfusions were administered in our designated population. Of those, 50.4% were platelets, 44.0% were red blood cells (RBC), 3.4% were cryoprecipitate, 1.4% were thawed plasma, and 0.8% were granulocytes. Those undergoing HSCT consumed 27.7% of total transfusions. Of all transfusions, there were 48 (2.7%) reported as possible TRs by nursing. Of those, 30 (1.7% of all transfusions) were adjudicated as true TRs. Fourteen (46.7%) of these true TRs were in patients with leukemia, 9 (30.0%) with HSCT, 5 (16.7%) with solid tumors, and 2 (6.7%) with aplastic anemia. Of the 9 reactions in HSCT patients, 4 occurred in allogeneic transplant recipients (3 umbilical cord blood and one matched unrelated donor) and 5 were in those receiving autologous HSCT. In HSCT patients, 1.8% of transfusions resulted in TRs compared to 1.6% in non-HSCT patients. Of the products triggering reactions, platelets accounted for 22 TRs (73.3%) and RBCs accounted for 8 TRs (26.7%). Of all 30 TRs, 15 (50%) were classified as febrile non-hemolytic transfusion reactions (FNHTR), 14 (46.7%) were considered allergic reactions, and 1 (3.3%) was diagnosed as transfusion-associated circulatory overload. Pre-medication was given in 22 (76.7%) of transfusions causing reactions. Of the 18 reports that were not adjudicated as true TRs, most (n=15) were generated for fever, but deemed unrelated to transfusion. Our baseline analysis revealed a higher prevalence than our historical institutional prevalence (1.7% vs. 1.3%), consistent with higher rates of TRs in the pediatric population, but lower than the 2% quoted in the literature, suggesting either underreporting or a different TR phenotype in this population. This population had a higher prevalence of FNHTR than the general pediatric population (50.0% vs. 31.5%). High rates of pre-medication and comorbidities (resulting in fevers) may influence TR presentation in this population. [ABSTRACT FROM AUTHOR]
