Optimizing Ewing Sarcoma and Osteosarcoma Biopsy Acquisition: A Children's Oncology Group Bone Tumor Committee Consensus Statement.

Trends in diagnostic biopsy sample collection approaches for primary bone sarcomas have shifted in the past 2 decades. Although open/incisional biopsies used to be the predominant approach to obtain diagnostic material for Ewing sarcoma and osteosarcoma, image-guided core needle biopsies have increased in frequency and are safe for patients. These procedures are less invasive and reduce recovery times but have potential limitations.

Impact of the COVID-19 Pandemic Onset on the Early Careers of Pediatric Oncology Health Professionals and Researchers: A Report From the Children's Oncology Group Young Investigators Committee, Young SIOP Network, and Young SIOPE.

Introduction: The COVID-19 pandemic onset had a global debilitating impact on individuals and on burgeoning careers. In 2021, the Children's Oncology Group Young Investigators Committee, Young SIOP (International Society of Paediatric Oncology) Network, and Young SIOPE (European Society for Paediatric Oncology) co-sponsored a survey to explore the impacts of the first year of the pandemic on early-career pediatric oncology professionals with respect to working practices, productivity, professional and career development, personal wellbeing, and changing childcare needs.

Methods: The survey comprised demographic, multiple-choice, and free-text questions, and was distributed via email and social media with English, French, and Spanish versions available.

Consensus recommendations for systemic therapies in the management of relapsed Ewing sarcoma: A report from the National Ewing Sarcoma Tumor Board.

Ewing sarcoma (ES) is a malignant tumor of bone and soft tissue that most often occurs in children, adolescents, and young adults. Debate and controversy remain in the management of relapsed/refractory ES (RR-ES). The authors leveraged the expertise assembled by the National Ewing Sarcoma Tumor Board, a multidisciplinary virtual tumor board that meets monthly to discuss challenging cases of ES.

Access to innovative therapies in pediatric oncology: Report of the nationwide experience in Canada.

Background: The need for new therapies to improve survival and outcomes in pediatric oncology along with the lack of approval and accessible clinical trials has led to "out-of-trial" use of innovative therapies. We conducted a retrospective analysis of requests for innovative anticancer therapy in Canadian pediatric oncology tertiary centers for patients less than 30 years old between 2013 and 2020.

Methods: Innovative therapies were defined as cancer-directed drugs used (a) off-label, (b) unlicensed drugs being used outside the context of a clinical trial, or (c) approved drugs with limited evidence in pediatrics.
