The International Neuroblastoma Staging System stage for a PATIENT during a Children Teenagers and Young Adults Cancer Care Spell.
National Codes:
| CODE | STAGE | DESCRIPTION |
| 1 | 1 | Localised Tumour with complete gross excision, with or without microscopic residual disease; representative ipsilateral lymph nodes negative for Tumour microscopically (nodes attached to and removed with the primary Tumour may be positive). |
| 2A | 2A | Localised Tumour with incomplete gross excision; representative ipsilateral nonadherent lymph nodes negative for Tumour microscopically. |
| 2B | 2B | Localised Tumour with or without complete gross excision, with ipsilateral nonadherent lymph nodes positive for Tumour. Enlarged contralateral lymph nodes must be negative microscopically. |
| 3 | 3 | Unresectable unilateral Tumour infiltrating across the midline, with or without regional lymph node involvement; or localised unilateral Tumour with contralateral regional lymph node involvement; or midline Tumour with bilateral extension by infiltration (unresectable) or by lymph node involvement. The midline is defined as the vertebral column. Tumours originating on 1 side and crossing the midline must infiltrate to or beyond the opposite side of the vertebral column. |
| 4 | 4 | Any primary Tumour with dissemination to distant lymph nodes, bone, bone marrow, liver, skin, and/or other organs (except as defined for stage 4S). |
| 4S | 4S | Localised primary Tumour (as defined for stage 1, 2A, or 2B), with dissemination limited to skin, liver, and/or bone marrow (limited to infants younger than 1 year). Marrow involvement should be minimal (<10% of total nucleated CELLS identified as malignant by bone Biopsy or by bone marrow aspirate). More extensive bone marrow involvement would be considered to be stage 4 disease. The results of the MIBG (Meta-ldo-Benzyl-Guanidine) scan (if performed) should be negative for disease in the bone marrow. |
