How is RCC diagnosed?
Triple-phase contrast CT
USS
Biopsy- high false negative rate
Describe the staging system used in RCC.
Robson staging:

II-contained within Garota’s fascia
III- spread to renal vein
IV- metastases
How is RCC managed?
Radical/partial nephrectomy
What adjuvant therapies can be used in RCC?
