BackgroundOutcomes for children and adults with advanced soft tissue sarcoma are poor with traditional therapy. We investigated whether the addition of pazopanib to preoperative chemoradiotherapy would improve pathological near complete response rate compared with chemoradiotherapy alone.MethodsIn this joint Children's Oncology Group and NRG Oncology multicentre, randomised, open-label, phase 2 trial, we enrolled eligible adults (aged ≥18 years) and children (aged between 2 and 16 years) performance status score of at least 70. Patients received ifosfamide (2·5 g/m2 per dose intravenously on days 1-3 with mesna) and doxorubicin (37·5 mg/m2 per dose intravenously on days 1-2) with 45 Gy preoperative radiotherapy, followed by surgical resection at week 13. Patients were randomly assigned (1:1) using a web-based system, in an unmasked manner, to receive oral pazopanib (if patients

PurposeTo identify clinical and treatment variables associated with a higher risk of local failure in Ewing sarcoma patients treated on recent Children's Oncology Group protocols.Methods and materialsData for 956 patients treated with ifosfamide and etoposide-based chemotherapy on INT-0091, INT-0154, and AEWS0031 were analyzed. Local treatment modalities were defined as surgery, definitive radiation therapy (RT), or surgery plus radiation (S+RT). Five-year cumulative incidence of local failure was determined.ResultsThe local failure rate for the entire cohort was 7.3%, with a 3.9% rate for surgery, 15.3% for RT (P

Sarcomas represent less than 1% of adult cancers but account for approximately 21% of pediatric malignancies and pose great risks for mortality and morbidity in children and young adults. Both benign bone and soft-tissue tumors may not be life-threatening but can be limb-threatening. Missed diagnosis, misdiagnosis, and mismanagement of either benign or malignant tumors may lead to increased mortality and morbidity. A good understanding of the clinical presentation, radiographic findings, and treatment options is needed to make the proper diagnosis and successfully treat these patients. Children and young adults present unique challenges in the management these tumors. Often, there is no right or wrong answer. Surgeons must work with patients and their families to make the right reconstructive decision.
