The role of cytoreductive nephrectomy (CN), i.e. the removal of a kidney involved by cancer in patients with advanced kidney cancer with distant metastases, is the subject of intense debate among urologists and oncologists. For many years, CN has been considered the gold standard in the treatment of patients at this stage of the disease, especially in patients in good general health with no significant contraindications to surgical treatment. The starting point for questioning the validity of CN was the publication of the results of the cancer du rein metastatique nephrectomie et antiangiogéniques and SURTIME clinical trials (2018 and 2019, respectively), which questioned the validity of surgery in some patients with late-stage cancer. Given the complexity of the disease, the role of removing the involved kidney is the subject of much controversy. In recent years, several studies have been conducted to evaluate the efficacy and safety of nephrectomy in patients with metastatic kidney cancer, resulting in conflicting information regarding the eligibility criteria for patients in different risk groups. The aim of this article is to analyse the available data, provide an up-to-date review of the literature, and discuss the controversies and challenges related to CN in patients with metastatic kidney cancer. The present literature review aims to organize and systematize the current state of knowledge, which may help in making clinical decisions regarding qualification for CN in patients with advanced kidney cancer.
