Laparoscopic adrenal-sparing approach for children with bilateral pheochromocytoma in Von Hippel-Lindau disease.

Introduction: Von Hippel-Lindau disease (VHL) is a rare cause of hereditary bilateral Pheochromocytomas (PHEO). Traditionally, treatment has been total adrenalectomy due to a lifetime risk of developing new tumors. Limited data exists on the surgical management of bilateral PHEO in children with VHL.

Implications of Tumor Characteristics and Treatment Modality on Local Recurrence and Functional Outcomes in Children With Chest Wall Sarcoma: A Pediatric Surgical Oncology Research Collaborative Study.

Objective: To determine the impact of tumor characteristics and treatment approach on (1) local recurrence, (2) scoliosis development, and (3) patient-reported quality of life in children with sarcoma of the chest wall.

Summary Of Background Data: Children with chest wall sarcoma require multimodal therapy including chemotherapy, surgery, and/or radiation. Despite aggressive therapy which places them at risk for functional impairment and scoliosis, these patients are also at significant risk for local recurrence.

Optimization of percutaneous biopsy for diagnosis and pretreatment risk assessment of neuroblastoma.

Background: Image-guided percutaneous core needle biopsy (PCNB) is increasingly utilized to diagnose solid tumors. The objective of this study is to determine whether PCNB is adequate for modern biologic characterization of neuroblastoma.

Procedure: A multi-institutional retrospective study was performed by the Pediatric Surgical Oncology Research Collaborative on children with neuroblastoma at 12 institutions over a 3-year period.
