Children with cancer receive many medications outside the hospital administered by their caregivers. The study by Walsh et al. shows the number and types of medication errors in these patients.

Objective: Head and neck cancers represent critical challenges due to the restricted anatomical space in children and the proximity of critical neurovascular structures which can compromise complete tumor resection. Applications of Indocyanine green (ICG) near infrared (NIR) fluorescent image-guided surgery (FGS) have recently expanded into the pediatric population, emphasizing its relevance for tumor delineation and evaluation of tissue perfusion. The objectives of the present study are twofold.

Purpose: We evaluated whether combining a humanized antidisialoganglioside monoclonal antibody (hu14.18K322A) throughout therapy improves early response and outcomes in children with newly diagnosed high-risk neuroblastoma.

Patients And Methods: We conducted a prospective, single-arm, three-stage, phase II clinical trial.

Background: Data on primary hypothyroidism and its long-term impact on the health, cognition, and quality of life (QOL) of childhood cancer survivors are limited. This study examined the prevalence of and risk factors for primary hypothyroidism and its associations with physical, neurocognitive, and psychosocial outcomes.

Methods: This was a retrospective study with a cross-sectional health outcome analysis of an established cohort comprising 2965 survivors of childhood cancer (52.

Although outcomes for patients with high-risk neuroblastoma improved after the addition of a chimeric anti-GD2 monoclonal antibody (dinutuximab) as treatment for minimal residual disease, nearly half of these patients die of disease. Recent studies demonstrated efficacy of the combination of chemotherapy with anti-GD2 mAb in patients with relapsed or newly diagnosed disease. This retrospective case series describes 6 patients treated at St Jude Children's Research Hospital with an induction regimen containing dinutuximab and chemotherapy, followed by consolidation and postconsolidation therapy.

Article Synopsis
  • Talazoparib was studied in combination with irinotecan, with or without temozolomide, in a phase I trial for pediatric patients with recurrent or resistant solid tumors, particularly Ewing sarcoma.
  • The trial involved 41 patients, revealing a response rate of 10.3% for arm A (talazoparib + irinotecan) and 25% for arm B (talazoparib + irinotecan + temozolomide), with common toxicities including neutropenia and thrombocytopenia.
  • Pharmacokinetic analysis showed no drug interactions between talazoparib and irinotecan, while SLFN11 positivity correlated with better treatment responses.

Infantile fibrosarcoma (IFS) is a rare pediatric cancer that typically presents early in life. Surgical resection is commonly curative; however, resection is sometimes not possible requiring additional multimodal treatment. IFS commonly harbors a fusion in one of the neurotrophic receptor tyrosine kinase (NTRK) genes.

Introduction: Handoffs and transitions of care are common weak points in healthcare provider communication as patients move between sites. With no consistent pattern of communication between St. Jude Children's Research Hospital (St.

Purpose: We sought to evaluate whether combining a humanized antidisialoganglioside mAb (hu14.18K322A) with induction chemotherapy improves early responses and outcomes in children with newly diagnosed high-risk neuroblastoma.

Patients And Methods: We conducted a prospective nonrandomized, single-arm, two-stage, phase II clinical trial.

Children with trisomy 18 are surviving longer and undergoing more aggressive life-sustaining therapy. This report describes two patients with trisomy 18 and hepatoblastoma (HB) successfully resected in the setting of significant pulmonary hypertension. Forty-four previously published cases of the association between HB and trisomy 18 are reviewed.

The transition from a committed progenitor cell to one that is actively differentiating represents a process that is fundamentally important in skeletal myogenesis. Although the expression and functional activation of myogenic regulatory transcription factors (MRFs) are well known to govern lineage commitment and differentiation, exactly how the first steps in differentiation are suppressed in a proliferating myoblast is much less clear. We used cultured mammalian myoblasts and an RNA interference library targeting 571 kinases to identify those that may repress muscle differentiation in proliferating myoblasts in the presence or absence of a sensitizing agent directed toward CDK4/6, a kinase previously established to impede muscle gene expression.
