Surgery is an important part of the treatment of neuroblastomas. Most of the tumours develop in the adrenal gland but frequently invade the neighbouring organs including the complex network of nerves in this region. Other tumours involve the nerves that run on either side of the spine and can therefore be found at any place from the neck to the pelvis. In this location, tumours may extend and compress the spinal cord resulting in paraplegia (weakness of the legs) or sphincter function disturbance (difficulties with bladder or bowel). Finally, some abdominal neuroblastomas arise from the nerve network that surrounds the large vessels of the body that supply blood to the major abdominal organs. They are the most difficult to remove. More generally, the difficulties to remove a neuroblastoma are more or less proportional to the aggressiveness of the tumour.

The surgery group is involved in the development of all SIOPEN protocols. Representatives of the group direct the analysis of surgery data for publication and participate in the analysis and preparation of papers for publication by the body of SIOPEN. The group also provide a support service for advice with particularly challenging patients.

The Surgery Committee is chaired by Dr Sabine Sarnacki.
