Abstract
BACKGROUND: Open surgical biopsy is traditionally advocated prior to initiating therapy in UKCCLG neuroblastoma protocols. We report a single centre experience comparing the utility of open biopsy vs image guided needle biopsy in aiding the definitive diagnosis and risk stratification of neuroblastoma - (Shimada classification, MYCN expression, cytogenetics - 1p 11q, 17 q). METHODS: Medical records of all new cases of neuroblastoma presenting to a single UKCCLG centre during January 2002-July 2013 were examined. RESULTS: Thirty nine patients underwent a biopsy of primary tumour for neuroblastoma during the study. Twenty one children had open biopsy and eighteen cases had a needle biopsy. Staging of neuroblastoma revealed - stage 4 (n=26), stage 3 (n=7), stage 2 (n=3) and stage 4S (n=3). Sites of primary tumour were adrenal gland (n=20), abdomen (n=12), thoracic (n=4), abdomino-thoracic (n=2) and abdomino pelvic regions (n=1). All patients (open vs needle) had adequate tissue retrieved for histological diagnosis of neuroblastoma. One needle and one open biopsy case did not have MYCN status determined despite adequate tissue sampling. Seventeen patients (7 open and 10 needle biopsies) had 1p and 17q status reported in MLPA testing (Multiplex Ligation-dependent Probe Amplification). No single patient required a repeat tumour biopsy. Morbidity in the series was minimal with only one child - open biopsy group, requiring emergent laparotomy to control bleeding from an abdominal primary tumour. No complications were recorded with needle biopsy. CONCLUSIONS: Open and image guided needle biopsy appear to yield adequate tissue sampling for diagnosis, risk classification and staging of neuroblastoma. Further larger co-operative studies may usefully guide national and international protocols.
