There are two methods of neuroblastoma staging, one that is based on post-operative patients (INSS) and one developed for pre-treatment patients (INRGSS).
International Neuroblastoma Staging System (INSS)
This staging system is for post-operative patients and mainly for prognosis 1:
system propsed by the International Childhood Liver Tumours Strategy Group (previously called Société Internationale d’Oncologie Pédiatrique - Epithelial Liver Tumour Study Group - SIOPEL) aims for
staging and risk stratification of liver tumours at diagnoisis.

Staging of juvenile nasopharyngeal angiofibromas is performed with cross-sectional imaging, and relies on identification of local tumour extent, and invasion of adjacent spaces. For a discussion of this entity please refer to the parent article: juvenile nasopharyngeal angiofibroma.
Staging of Legg-Calve-Perthes syndrome refers to x-ray abnormalities, and represents 4 phases of the disease:
stage I: early
asymmetric femoral epiphyseal size (smaller on affected side)
apparent increased density of the femoral head epiphysis
widening of the medial joint space
blurring of ...
Wilms' tumour staging is largely anatomical and relates to the invasion and spread of the tumour. Where there is invasion or metastasises, prognosis is poorer. Wilms tumour, is one of the more common childhood malignancies.
