The majority of clinical trials included a thoroughly selected population of patients predominantly with clear-cell renal cell carcinoma (RCC), without brain metastases and with a good somatic status. Due to the fact that in routine practice, the patient population is more heterogeneous (patients with non-clear cell RCC, brain metastases, and an ECOG somatic status of > 1, the questions arise of whether it is effective and expedient to use target drugs in this group of patients. The results of
