I want to express my deep gratitude to all the medical staff of the oncohematology department, who work miracles every day-return people to health, life, and help fight the disease. It is rare to find so many excellent specialists and just kind and sympathetic people in one team. On my own behalf, I would like to express my special gratitude to the Head of the department, M. V. Tumanova, Professor A.V. Pivnik, the attending physician, L. I. Nikerova, and the procedural nurse, S. Dorogova. In my personal experience and opinion, this is the best hematology department of the mountains. Moscow. It is a pity that there are so few such departments and such excellent doctors in our city!
