Surgical management of neuroblastoma.

Overview

Neuroblastoma treatment remains challenging but has been advanced by the establishment of clinical and biological variables that determine prognostic risk. Risk-based therapy currently is the hallmark of neuroblastoma treatment. Initially, stage and age were the prime determinants of survival used in clinical practice. The Shimada histopathologic classification added to the former 2 and biochemical markers like the serum ferritin, lactic dehydrogenase, and neuron-specific enolase also provided information regarding prognosis. The current era of neuroblastoma therapy has been influenced heavily by advances in molecular biology, most notably the identification of the MYCN oncogene and the application of recombinant DNA methods to identification of chromosomal deletions. Current risk assessment includes age, stage, histopathology, and biochemical markers but also analyses performed on DNA extracted from fresh tumors. This places the onus of obtaining an adequate quantity and quality of fresh neuroblastoma tissue directly on the pediatric surgeon who performs the initial biopsy.
