The following review aims to provide contemporary information on therapeutic nuclear medicine procedures in paediatric malignancies. Neuroblastoma is the most common paediatric extra cranial solid cancer characterized by meta-iodobenzylguanidine (mIBG) avidity in >/=90% of patients. There exists approximately a 30-year experience with I-131-mIBG treatment. Ongoing efforts include a more standardized approach including dosimetric data for patient selection and treatment guidance of I-131-mIBG therapy. Neuroendocrine tumours (NETs) are very rare neoplasms in the paediatric population accounting for <1% of all paediatric malignancies. These neoplasms are characterized by the presence of neuroamine uptake mechanisms and/or peptide receptors at the cell membrane. These features constitute the basis of the clinical use of peptide receptor radionuclide therapy (PRRNT) using radiolabeled somatostatin analogues. Osteosarcoma is the most common primary bone tumour in children usually treated with chemotherapy and surgery. In palliative situations bone seeking radionuclide therapies (strontium-89 [Sr-89], rhenium-186 hydroxyethylene diphosphonate [Rh-186 HEDP] and Samarium-153-ethylene diamine tetramethylene phosphonic acid [Sm-153-EDTMP]) may be offered to patients with painful metastatic osteosarcoma or in case of recurrent bone sites inaccessible to local therapies (surgery, external irradiation). Thyroid cancer is a rare childhood malignancy with an approximate incidence of 0.54 per 100000 per year but is the most frequent tumour of endocrine glands in children and adolescents. Management includes radioiodine therapy but there are some distinct differences in comparison to adult thyroid cancer management.

There is nothing quite as devastating as hearing that word - neuroblastoma. In seconds your world is turned upside down and your normal life is but a distant memory. You are thrust into a confusing world full of fear. Your child has cancer.

We know. We have been there. The Neuroblastoma Foundation is here for you.

Welcome to our website. It is a place for you to find answers and ask questions. One of the primary goals of the Neuroblastoma Foundation is to ensure that parents, patients and health care professionals find the information they need to make the best treatment decisions possible for children and adults affected by neuroblastoma. There is a vast amount of information throughout the internet, much of which is encapsulated in medical jargon that is so complex that even many medical professionals have difficulty in interpreting its meaning. We are here to help to decipher this information and to make sure you (and your oncologist) understand exactly what it means to you. From treatment decisions to side effects we have parents and experts that have experienced it all and are willing to distill it for you.
