LiFraumeni syndrome (LFS) is a rare, autosomal dominant, hereditary disorder that is characterized by an increased risk for certain types of cancer, acute lymphoblastic leukemia (ALL), particularly. Germline TP53 mutations are associated with LFS. Genetic counseling and follow-up is essential for patients with LFS and their relatives. Special therapeutic approaches are needed for treatment of oncological disease in these patients. The article presents a series of clinical cases of patients with ALL and SLF, considers general issues of diagnosis and treatment of adult patients with this hereditary genetic syndrome. ⋯ Practical value of the research is the observation that the greater part of TP53 gene mutations in patients with Ph-negative B-cell ALL are germinal and associated with LFS.
