Everolimus is administered to patients with metastatic renal cell carcinoma in full daily dose of 10 mg or in reduced daily dose of 5 mg in case adverse effect occurred. These include metabolic adverse effects, mucositis, anorexia, and non-infectious pneumonitis and lead to increase in morbidity and decrease in the quality of life of the patient. Our goal was to evaluate the administration of fenofibrate and metformin in everolimus induced hypertriglyceridemia and hyperglycemia. The role of mTOR in lipid and glucose metabolism was researched in literature. The effect of including fenofibrate and metformin into metabolic adverse effect management guidelines in metastatic renal cell carcinoma patients who are administered everolimus was evaluated. Fenofibrate, metformin, and everolimus have several similar effects on intracellular level, therefore the effect of fenofibrate and metformin in treating everolimus induced metabolic adverse effects in metastatic renal cell carcinoma patients may be limited. The manifestation of metabolic adverse effects in patients treated with everolimus is not identical with metabolic syndrome or type II diabetes in standard population.
