The life expectancy of patients with metastatic luminal HER 2-negative breast cancer has stagnated at the level of 40 months for many years. The introduction of CDK4/6 inhibitors into practice has changed the standards of therapy, providing not only a significant increase in the time without progression while maintaining a high quality of life, but also significantly increasing overall survival. The presence of liver metastases determines an extremely unfavorable prognosis, with GH+HER 2-mBC reducing life expectancy to a median of 21 months. Endocrine therapy combined with ribociclib significantly increased overall survival rates on average per year, reaching medians of 36.1 and 46.5 months, depending on the line of treatment. This publication is devoted to liver metastases in breast cancer, in particular in the luminal HER 2-negative subtype. Epidemiological aspects are considered, the possibilities of modern systemic therapy are evaluated. A clinical case of successful therapy with ribociclib in a young patient with liver damage is presented.
