Collaborative Stage

Collaborative Stage for TNM 7 - Revised 01/24/2010 [ Schema ]

Retinoblastoma

CS Site-Specific Factor 1
Extension Evaluated at Enucleation

Note 1: For correct calculation of derived staging fields for this schema, CS Extension and Site-Specific Factor 1, Extension Evaluated at Enucleation, must both be coded, whether or not an enucleation was performed. Information from enucleation is EXCLUDED from CS Extension and coded only in Site-Specific Factor 1.
Note 2: Focal choroidal invasion is defined as a solid nest of tumor measuring less than 3mm in maximum diameter. Massive choroidal invasion is defined as a solid tumor nest 3mm or more in maximum diameter.

For the extension fields for this site, the mapping values for TNM, SS77, and SS2000 and the associated c, p, y, or a indicator are assigned based on the values in CS Extension, CS TS/Ext Eval, and Site-Specific Factor 1 as shown in the Special Calculation Table for AJCC Stage and Special Calculation Table for SEER Summary Stage.
