Аннотация:Cutaneous melanoma (CM), breast cancer (BC) and lung cancer (LC) metastasize to the brain most frequently. Early diagnosis of cerebral metastases is challenging and requires new prognostic criteria. Imbalance of thyroid and glucocorticoid hormones changes the growth and development of malignant tumors. The purpose of the study was to identify readily available prognostic criteria for cerebral metastases in cancer patients at various stages of treatment and follow-up.
