The incidence of malignant neoplasms is steadily increasing every year. In addition to common localizations, oncologists encounter non-standard tumors that require a personalized approach to treatment depending on the clinical situation. In recent decades, there has been significant progress in the creation of pharmacological drugs that are successfully used in the treatment of cancer, which selectively affect various targets in tumor cells. The article presents a clinical case of diagnosis and treatment of an anterior mediastinal tumor without organospecificity. An effective option for drug therapy aimed at targets found in tumor cells is described. The presented example demonstrates an individualized approach to the choice of treatment for a cancer patient and the effectiveness of its use.
