From: Ganglioside GD2 expression is maintained upon recurrence in patients with osteosarcoma
Expression of GD-2 in osteosarcoma cores. Cores taken from the primary biopsy, metastases at diagnosis, treated resection and upon recurrence were stained with a GD-2 specific antibody and examined via immunohistochemistry. Three independent observers scored the samples on a scale from – to +++. No significant difference in expression was seen between primary biopsy/treated resection samples versus recurrent samples (p = 0.15).
