Chronic myeloid leukemia is found in approximately 20% of newly diagnosed cases of leukemia in adults. In Europe and North America, chronic myeloid leukemia ranks third among leukemias (after acute leukemias and chronic lymphoblastic leukemia). The problem of diagnosis, treatment, rehabilitation and adaptation of patients with chronic myeloid leukemia is relevant, as there is a gradual increase in the incidence of this disease both in the world and in our country. Some progress has been achieved in the treatment of patients with oncohematological diseases, in particular chronic myeloid leukemia. Chronic myeloid leukemia is a clonal myeloproliferative disease in which as a result of specific translocation of chromosomal sites between 9 and 22 chromosomes, a khimeric BCR-ABL gene with tyrosine kinase activity is formed. The purpose of the study was to investigate the main biochemical parameters that characterize protein and pigment metabolism, the activity of key enzymes in patients with chronic myeloblastic leukemia at different stages of the disease for further prospects of optimizing diagnosis, predicting the course of the disease in clinical practice. Materials and methods. The functional state of liver in 77 patients at different stages of chronic myeloid leukemia was studied. All patients admitted to the hospital were examined with the use of clinical, laboratory, instrumental and special research methods, and were consulted by specialists of related specialties, if necessary. The main biochemical parameters that characterize protein and pigment metabolism, the activity of key enzymes in patients with chronic myeloid leukemia of peripheral venous blood was determined by the method of V. Menshikov (1987). Results and discussion. The content of biochemical parameters that characterize protein and pigment metabolism, the activity of key enzymes in patients with chronic myeloid leukemia has been studied. It was found that biochemical parameters that characterize protein and pigment metabolism, the activity of key enzymes in patients with chronic myeloid leukemia is associated with an increase in the studied indicator (p<0,05). The article discusses the possible causes and pathogenetic mechanisms of the identified changes. As the disease progressed the changes of protein, pigment and enzyme kinds of metabolism were revealed. The article discusses possible pathophysiological mechanisms of the identified changes. Conclusion. In patients with chronic myeloid leukemia, there is an imbalance in protein, pigment metabolism, and the activity of some liver enzymes. With the progression of chronic myeloid leukemia, the functional state of the liver deteriorates
