Chromophobe renal cell carcinoma is usually a relatively indolent form of kidney cancer with low risk of metastases. In our study we show that if initial kidney tumors present with large size, or with sarcomatoid features, closer follow-up is needed to identify and promptly treat patients with a higher risk of metastatic disease and subsequently a worse prognosis.
