6. Renal Cancer Definition
Approximately 90% of renal cancers are Renal Cell Carcinomas  ( RCC), various different subtypes of RCC exist, the most common being clear cell. Rarer types of renal cancer include cancer of the ureter and Transitional Cell Carcinoma ( TCC). The treatment of these cancers is different from RCC, and more similar to that of bladder cancer therefore these tumour types are included in the QPIs for bladder cancer.
The Renal Cancer QPI Development Group therefore agreed that all QPIs developed by them would focus on Renal Cell Carcinoma ( RCC) and these two terms ( RCC and renal cancer) are used interchangeably throughout this document.
