Кidney injury is a frequent and significant complication of cancer and cancer therapy. The kidneys are susceptible to injury from malignant infiltration, damage by metabolites of malignant cells, glomerular injury, nephrotoxic drugs including chemotherapeutic agents. Also bone marrow transplantation complications, infections with immune suppression (including septicemia), tumor lysis syndrome should be taken into account. Chemotherapeutic agents are a common cause of acute kidney injury but can potentially lead to chronic kidney disease development in cancer patients. This article summarizes risk factors of acute kidney injury in cancer patients. Risk factors are divided into two groups. The systemic are decrease of total circulating blood volume, infiltration of kidney tissue by tumor cells, dysproteinemia, electrolyte disturbances. The local (renal) risk factors are microcirculation disturbances, drugs biotransformation with formation of reactive oxygen intermediates, high concentration of nephrotoxic agents in proximal tubules and its sensitivity to ischemia. Drug-related risk factors include: drugs combination with cytotoxic effect high doses long term use necessity, direct cytotoxic effect of not only chemotherapeutic agents but also its metabolites, mean solubility forming intratubular precipitates. Early diagnosis, timely prevention and treatment of these complications provide significantly improve nononcologic results of treatment.
