[Pathology of the kidneys in malignant tumors of various localizations and antitumor therapy].

Non-tumorlesions of the kidneys in malignant neoplasms are very diverse. They can alter the results of chemotherapy and lead to death in the long term. In this regard, the related discipline of onconephrology has increasingly begun to be identified, which emphasizes the importance of diagnosing non-tumor kidney lesions in this category of patients. This review is devoted to the classification, diagnosis, course, prevention and treatment of non-tumor kidney lesions in patients with malignant neoplasms. There are four groups of lesions: mechanical damage; nephropathy due to anticancer therapy; paraneoplastic nephropathy; lesions associated with metabolic disorders. Kidney lesions in patients with malignant neoplasms are characterized by a variable course. In some cases, acute renal failure develops. Others are characterized by an asymptomatic course with an outcome in nephrosclerosis. Timely diagnosis and treatment of kidney lesions in malignant neoplasms can improve the quality of life and prognosis of patients with malignant neoplasms.
