If CIA treatment is not effective, it will affect the normal implementation of chemotherapy regimens, and reduce the quality of life of patients and shorten clinical survival. At present, CIA has serious shortcomings in treatment rate and unsatisfactory therapeutic effect. It is often forced to reduce the dose of chemotherapy or delay chemotherapy due to anemia that cannot be rapidly and effectively treated in clinical practice. These problems are mainly related to factors such as complex etiology of the disease, late timing of clinical intervention, and certain limitations in existing treatment options. Therefore, disease management needs to further strengthen the concept of early diagnosis and early treatment to avoid the increased clinical burden due to the severity of anemia.
