RESUMO
BACKGROUND: Treatment for certain childhood cancers and nonmalignant conditions can lead to future infertility and gonadal failure. The risk of treatment delay must be considered when offering fertility preservation (FP) options. We examined the timeline from FP referral to return to treatment (RTT) in pediatric patients who underwent FP due to iatrogenic risk for infertility. METHODS: A retrospective review was performed of patients with FP consultation due to an increased risk of iatrogenic infertility at Ann & Robert H. Lurie Children's Hospital of Chicago from 2018 to 2022. Data on diagnosis, age, treatment characteristics, and procedure were collected. RESULTS: A total of 337 patients (n = 149 with ovaries, n = 188 with testes) had an FP consultation. Of patients with ovaries, 106 (71.1%) underwent ovarian tissue cryopreservation (OTC), 10 (6.7%) completed ovarian stimulation/egg retrieval (OSER), and 33 (22.1%) declined FP. Of the patients with testes, 98 (52.1%) underwent testicular tissue cryopreservation (TTC), 48 (25.5%) completed sperm banking (SB), and 42 (22.3%) declined FP. Median time from referral to FP consultation was short (ovaries: 2 days, range: 0-6; testes: 1 day, range: 0-5). OSER had a significantly longer RTT versus OTC and no FP (52.5 vs.19.5 vs. 12 days, p = .01). SB had a significantly quicker RTT compared to TTC or no FP (9.0 vs. 21.0 vs. 13.5 days; p = .008). For patients who underwent OTC/TTC and those who declined FP, there was no significant difference in time from consultation to treatment. CONCLUSIONS: It is feasible to promptly offer and complete FP with minimal delay to disease-directed treatment.

PURPOSE: Bosutinib is approved for adults with chronic myeloid leukemia (CML): 400 mg once daily in newly diagnosed (ND); 500 mg once daily in resistant/intolerant (R/I) patients. Bosutinib has a different tolerability profile than other tyrosine kinase inhibitors (TKIs) and potentially less impact on growth (preclinical data). The primary objective of this first-in-child trial was to determine the recommended phase II dose (RP2D) for pediatric R/I and ND patients. PATIENTS AND METHODS: In the phase I part of this international, open-label trial (ClinicalTrials.gov identifier: NCT04258943), children age 1-18 years with R/I (per European LeukemiaNet 2013) Ph+ CML were enrolled using a 6 + 4 design, testing 300, 350, and 400 mg/m2 once daily with food. The RP2D was the dose resulting in 0/6 or 1/10 dose-limiting toxicities (DLTs) during the first cycle and achieving adult target AUC levels for the respective indication. As ND participants were only enrolled in phase II, the ND RP2D was selected based on data from R/I patients. RESULTS: Thirty patients were enrolled; 27 were evaluable for DLT: six at 300 mg/m2, 11 at 350 mg/m2 (one DLT), and 10 at 400 mg/m2 (one DLT). The mean AUCs at 300 mg/m2, 350 mg/m2, and 400 mg/m2 were 2.20 µg h/mL, 2.52 µg h/mL, and 2.66 µg h/mL, respectively. The most common adverse event was diarrhea (93%; ≥grade 3: 11%). Seven patients stopped because of intolerance and eight because of insufficient response. Complete cytogenetic and major molecular response to bosutinib appeared comparable with other published phase I/II trials with second-generation TKIs in children. CONCLUSION: Bosutinib was safe and effective. The pediatric RP2D was 400 mg/m2 once daily (max 600 mg/d) with food in R/I patients and 300 mg/m2 once daily (max 500 mg/d) with food in ND patients, which achieved targeted exposures as per adult experience.

Somatic mutations in isocitrate dehydrogenase (IDH) genes occur frequently in adult acute myeloid leukemia (AML) and less commonly in pediatric AML. The objective of this study was to describe the prevalence, mutational profile, and prognostic significance of IDH mutations in AML across age. Our cohort included 3141 patients aged between <1 month and 88 years treated on Children's Cancer Group/Children's Oncology Group (n = 1872), Southwest Oncology Group (n = 359), Eastern Cooperative Oncology Group (n = 397) trials, and in Beat AML (n = 333) and The Cancer Genome Atlas (n = 180) genomic characterization cohorts. We retrospectively analyzed patients in 4 age groups (age range, n): pediatric (0-17, 1744), adolescent/young adult (18-39, 444), intermediate-age (40-59, 640), older (≥60, 309). IDH mutations (IDHmut) were identified in 9.2% of the total cohort (n = 288; IDH1 [n = 123, 42.7%]; IDH2 [n = 165, 57.3%]) and were strongly correlated with increased age: 3.4% pediatric vs 21% older, P < .001. Outcomes were similar in IDHmut and IDH-wildtype (IDHWT) AML (event-free survival [EFS]: 35.6% vs 40.0%, P = .368; overall survival [OS]: 50.3% vs 55.4%, P = .196). IDH mutations frequently occurred with NPM1 (47.2%), DNMT3A (29.3%), and FLT3-internal tandem duplication (ITD) (22.4%) mutations. Patients with IDHmut AML with NPM1 mutation (IDHmut/NPM1mut) had significantly improved survival compared with the poor outcomes experienced by patients without (IDHmut/NPM1WT) (EFS: 55.1% vs 17.0%, P < .001; OS: 66.5% vs 35.2%, P < .001). DNTM3A or FLT3-ITD mutations in otherwise favorable IDHmut/NPM1mut AML led to inferior outcomes. Age group analysis demonstrated that IDH mutations did not abrogate the favorable prognostic impact of NPM1mut in patients aged <60 years; older patients had poor outcomes regardless of NPM1 status. These trials were registered at www.clinicaltrials.gov as #NCT00070174, #NCT00372593, #NCT01371981, #NCT00049517, and #NCT00085709.

Despite being considered "standard of care" by many organizations, fertility and reproductive health communications and counseling practices remain inconsistent for adolescents and young adults (AYAs) newly diagnosed with cancer and during survivorship. One factor known to affect how information is provided and received in the medical setting is health literacy. Providers should consider health literacy to optimize reproductive health communication with AYAs as they cope with their diagnosis, understand what it means for their future, process information about treatment options, learn about their potential harmful effects on fertility, make quick decisions about fertility preservation, and navigate a future family planning course. Thus, the objectives of this manuscript are to (a) summarize literature on reproductive health literacy; (b) describe health literacy frameworks; (c) examine ways to assess health literacy; and (d) identify ways to enhance clinician-patient communication in the AYA oncofertility setting.

Objective: The goal of this report is to describe, through a series of 5 cases, the clinical response and safety of alpelisib (BYL719) use in children and adults with PIK3CA-related overgrowth spectrum (PROS) disorders at our center. Methods: We reviewed clinical records of 5 patients from October 2019 through September 2021 followed by the pediatric hematology and multidisciplinary vascular anomalies teams at the Monroe Carell Jr. Children's Hospital at Vanderbilt (MCJCHV). All patients carried a clinical or genetic diagnosis of PROS and were treated with alpelisib provided by a Novartis managed access program. Results: We highlight improvement in reported symptoms, objective overgrowth measurements, and quality of life to varying degrees in all patients. We note dose-dependent hyperglycemia and gastrointestinal side effects in 2 of the 5 patients. No patients experienced any serious side effects. Conclusion: This case series reports on the real-world use of PI3K-α inhibition in the management of PROS. Ongoing clinical trials will provide efficacy and safety data as these drugs become more widely used in patients with vascular anomalies and syndromes secondary to somatic PIK3CA mutations.
RESUMO
Pediatric acute myeloid leukemia (AML) develops from clonal expansion of hematopoietic precursor cells and is characterized by morphologic and cytomolecular heterogeneity. Although the past 40 years have seen significant improvements in overall survival, the prevailing treatment challenges in pediatric AML are the prevention of relapse and the management of relapsed disease. Approximately 25% of children and adolescents with AML suffer disease relapse and face a poor prognosis. Our greater understanding of the genomic, epigenomic, metabolomic, and immunologic pathophysiology of relapsed AML allows for better therapeutic strategies that are being developed for pediatric clinical trials. The development of biologically rational agents is critical as conventional chemotherapeutic salvage regimens are not effective for all patients and pose risk of organ toxicity in heavily pretreated patients. Another major barrier to improvement in outcomes for relapsed pediatric AML is the historic lack of availability and participation in clinical trials. There are ongoing efforts to launch multinational clinical trials of emerging therapies. The purpose of this review is to summarize currently available and newly developed therapies for relapsed pediatric AML.

Vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an effective strategy to prevent serious coronavirus disease 2019 (COVID-19) and is important for oncology patients. mRNA-based COVID-19 vaccines are contraindicated in those with a history of severe or immediate allergy to any vaccine component, including polyethylene glycol (PEG)2000. Patients with acute lymphoblastic leukemia/lymphoma receive asparaginase conjugated to PEG5000 (PEG-ASNase) and those with PEG-ASNase-associated hypersensitivity may be unnecessarily excluded from receiving mRNA COVID-19 vaccines. We, therefore, surveyed oncologists on COVID-19 vaccine counseling practice and vaccination outcomes in COVID-19 vaccination-eligible patients and show safe receipt of mRNA vaccines despite PEG-ASNase hypersensitivity.

B-cell acute lymphoblastic leukemia (B-ALL) is the most common pediatric malignancy with a highly favorable overall prognosis. Central nervous system (CNS) relapse of B-ALL is relatively rare and is associated with inferior survival outcomes. We present two patients with B-ALL who developed isolated CNS relapse following confirmed infection with severe acute respiratory syndrome coronavirus 2. In addition to individual and disease factors, we posit that delays in therapy together with immune system modulation because of severe acute respiratory syndrome coronavirus 2 may account for these 2 cases of CNS relapsed B-ALL. We report on this clinical observation to raise awareness of this potential association.

Langerhans cell histiocytosis (LCH) is the most common histiocytic disorder. Liver involvement is seen in 10.1% to 19.8% of patients with LCH and can lead to secondary sclerosing cholangitis requiring liver transplantation (LT). We describe the characteristics and outcomes of patients undergoing LT for LCH. All patients undergoing a first LT for LCH in the United States were identified in the Scientific Registry of Transplant Recipients (SRTR) database (1987-2018). The Kaplan-Meier curve method and log-rank tests evaluated post-LT survival. A systematic literature review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statement. A total of 60 LCH LT recipients were identified in the SRTR, and 55 patients (91.7%) were children with median total bilirubin levels at LT of 5.8 mg/dL (interquartile range [IQR], 2.7-12.9). A total of 49 patients (81.7%) underwent deceased donor LT (DDLT). The 1-year, 3-year, and 5-year patient survival rates were 86.6%, 82.4%, and 82.4%, respectively. The systematic review yielded 26 articles reporting on 50 patients. Of the patients, 41 were children (82.0%), 90.0% had multisystem LCH, and most patients underwent DDLT (91.9%; n = 34/37). Pre-LT chemotherapy was administered in 74.0% and steroids in 71.7% (n = 33/46) of the patients, and a recurrence of LCH to the liver was reported in 8.0% of the patients. Of the 50 patients, 11 (22.0%) died during a median follow-up of 25.2 months (IQR, 9.0-51.6), and the 1-year patient survival rate was 79.4%. LT can be considered as a feasible life-saving option for the management of liver failure secondary to LCH in well-selected patients.

BACKGROUND: Pediatric patients with cancer undergo repeated painful procedures, including bone marrow aspirations and biopsies (BMABs). Optimal management of procedure-related pain can reduce discomfort, anxiety, and distress. METHODS: Children with neuroblastoma were randomly assigned to 1 of 2 arms on a prospective, single-blind, crossover trial conducted at Memorial Sloan Kettering Cancer Center from October 2016 to January 2018 (www.clinicaltrials.gov, identifier NCT02924324). Participants underwent 2 sequential BMABs: one with general anesthesia (GA) alone, the other with GA plus local anesthesia (LA) (GA + LA). The objective was to assess procedure-related pain and its interference with quality of life (QoL) with GA versus GA + LA. Primary outcome was percentage of participants requiring postprocedural opioids. Secondary outcomes were total opioid and nonopioid analgesics, pain scores, time to first analgesic, QoL, and toxicity. Management of postprocedural pain was standardized. RESULTS: Of 56 participants randomly assigned (3-16.5 years old), 46 completed both procedures. There was no significant difference in percentage of participants requiring opioids with GA versus GA + LA (24% vs 20%, P = .5). Pain scores in the recovery room were significantly lower for GA + LA versus GA (median [IQR]: 0 [0-2] vs 2 [0-4], P = .002). There were no statistically significant differences in total opioid or nonopioid analgesic, 6- and 24-hour pain scores, median time to first analgesic, or pain interference. No adverse events occurred. CONCLUSIONS: LA was associated with significant improvement in pain scores in the immediate recovery period. LA did not reduce postprocedural opioid use, nor did it improve QoL for patients undergoing BMAB with GA.
