Management of Advanced Neuroblastoma

Clinical Presentation and Diagnosis

  • Elevated urinary catecholamine levels (vanillylmandelic acid [VMA]) are found in the majority of patients with neuroblastoma and are considered essential in the diagnostic workup, as recommended by the National Comprehensive Cancer Network 1
  • Periorbital ecchymosis (raccoon eyes) is a characteristic finding in metastatic neuroblastoma, often indicating orbital or periorbital involvement, according to the American College of Radiology 2
  • Tissue diagnosis is essential for confirmation and molecular testing of neuroblastoma, though fine-needle aspiration is not recommended, as stated by the National Comprehensive Cancer Network 1

Treatment Approach Rationale

  • For advanced neuroblastoma (Stage III/IV), neoadjuvant chemotherapy followed by delayed surgical resection allows for better assessment of tumor biology and response to therapy, as recommended by the National Comprehensive Cancer Network 1
