Survival after bone marrow transplantation for myelofibrosis is 3 to 4 years, and a few patients can also survive for about 10 years or more. Often, bone marrow transplantation is actually a transplantation of hematopoietic stem cells, which can prolong progression-free survival and lead to significant improvement in clinical symptoms, and together with chemotherapy, can also lead to a relatively longer survival time. The survival time of myelofibrosis patients without treatment is only 30 to 36 months. After stem cell bone marrow transplantation, the survival time can be further extended to 3-4 years. A small number of patients who respond well to bone marrow transplantation can survive for 10 years or more. Bone marrow transplantation can reduce tumor load and prolong survival, but it cannot completely cure myelofibrosis. As a result, the mortality rate for patients with myelofibrosis remains high. Patients with myelofibrosis should go to the hospital in time and under the guidance of the physician, undergo comprehensive treatment such as bone marrow transplantation and chemotherapy (rucotinib) in order to improve their condition as soon as possible and prolong their survival time as much as possible.
