RESUMO
BACKGROUND: Patients with hepatoblastoma (HB) have a higher risk of congenital heart defects (CHD). There is limited literature on the management and outcomes of these patients. The purpose of this study was to identify demographics and outcomes of these patients in a single tertiary referral center. METHODS: An Institutional Review Board (IRB)-approved retrospective chart review of patients with newly diagnosed HB from October 2004 to January 2021 was performed. CHD was defined as the presence of a septal defect, patent ductus arteriosus, pulmonary atresia, or bicuspid aortic valve. Chi-square and t-test were utilized for statistical analyses. RESULTS: Of the 151 patients diagnosed with HB during the study timeframe, 29 patients were found to have CHD. Five-year overall survival (OS) for non-CHD HB patients was 81.9% compared to 68.9% in the CHD cohort (p = .12). The 5-year OS for patients without surgically intervened CHD was 63.6% compared to 70.5% for those with surgically repaired CHD (p = .88). Pre-treatment extent of tumor IV was present more often in patients with HB and CHD who passed away (6/9, 66.7%) compared to those who survived (3/16,18.8%, p = .01). CONCLUSIONS: Patients with HB and CHD have similar survival compared to those without CHD. Our data support that patients with HB and CHD should be treated with curative intent including cardiac surgical intervention, medical oncology therapy, and oncological surgery for their HB.
RESUMO
BACKGROUND: We characterize the incidence and 5-year survival of children and adolescents with neuroblastoma stratified by demographic and clinical factors based on the comprehensive data from United States Cancer Statistics (USCS) and the National Program of Cancer Registries (NPCR). METHODS: We analyzed the incidence of neuroblastoma from USCS (2003-2019) and survival data from NPCR (2001-2018) for patients less than 20 years old. Incidence trends were calculated by average annual percent change (AAPC) using joinpoint regression. Differences in relative survival were estimated comparing non-overlapping confidence intervals (CI). RESULTS: We identified 11,543 primary neuroblastoma cases in USCS. Age-adjusted incidence was 8.3 per million persons [95% CI: 8.2, 8.5], with an AAPC of 0.4% [95% CI: -0.1, 0.9]. Five-year relative survival from the NPCR dataset (n = 10,676) was 79.7% [95% CI: 78.9, 80.5]. Patients aged less than 1 year had the highest 5-year relative survival (92.5%). Five-year relative survival was higher for non-Hispanic White patients (80.7%) or Hispanic patients (80.8%) compared to non-Hispanic Black patients (72.6%). CONCLUSION: Neuroblastoma incidence was stable during 2003-2019. Differences in relative survival exist by sex, age, race/ethnicity, and stage; patients who were male, older, non-Hispanic Black, or with distant disease had worse survival. Future studies could seek to assess the upstream factors driving disparities in survival, and evaluate interventions to address inequities and improve survival across all groups.

PURPOSE: The objective of this study was to determine the recommended Phase 2 dose (RP2D) of pevonedistat, a first in class inhibitor of NEDD8 activating enzyme, in combination with irinotecan (IRN) and temozolomide (TMZ) in children with cancer. METHODS: This Phase 1 study used a rolling 6 design to evaluate escalating doses of pevonedistat in combination with standard doses of IRN and TMZ in pediatric patients with recurrent/refractory solid or CNS tumors. During cycle 1, pevonedistat was administered intravenously on days 1, 8, 10, and 12, with IRN (IV, 50 mg/m2) and TMZ (orally, 100 mg/m2), on days 8-12 of a 28-day cycle. In subsequent cycles, pevonedistat was administered on days 1, 3, and 5, with IRN/TMZ on days 1-5 of a 21-day cycle. RESULTS: Thirty patients enrolled; all were eligible and evaluable for toxicity. Six patients each enrolled on pevonedistat dose levels (DL) 1 (15 mg/m2), 2 (20 mg/m2), 3 (25 mg/m2) and 4 (35 mg/m2) as well as an expanded pharmacokinetic (PK) cohort at DL4. The maximum tolerated dose (MTD) was not exceeded. 2/12 (17 %) patients treated at the RP2D (35 mg/m2) experienced a cycle 1 dose limiting toxicity (DLT). IRN is unlikely to affect the pharmacokinetics of pevonedistat. Two patients had a partial response and 6 patients had prolonged stable disease (> 6 cycles). CONCLUSIONS: Pevonedistat in combination with IRN/TMZ is well tolerated in children with solid or CNS tumors. The RP2D of pevonedistat is 35 mg/m2 on days 1, 3, 5 in combination with IRN/TMZ.
