†
The digit after the plus here indicates the number of instances where after review of the report free text, the LLM provided an updated label (See STable 3.1 for details)
‡
TFE3 was additionally matched to the older terminology- Xp11 translocation RCC. Similarly TFEB was matched to t(6,11) translocation RCC. These terms were used in previous versions of CAP kidney cancer templates.
