Brief Summary

The pelvis and spine are common sites of primary and secondary bone tumors, and most patients require surgical treatment. However, due to bleeding, high tumor burden, and other reasons, iron deficiency anemia (IDA) is common in these patients. At present, allogeneic blood resources are scarce in China and even globally, and cancer patients cannot undergo autologous blood transfusion. In addition, there is a large amount of bleeding during pelvic and spinal open surgery, which collectively leads to a high incidence of perioperative anemia in patients with pelvic and spinal tumors, and even the loss of surgical opportunities. Therefore, perioperative blood management for bone tumor surgery is extremely important. The combination of intravenous iron and EPO has been proven to rapidly improve the hemoglobin levels of perioperative surgical patients in previous studies, but there is currently no research related to bone tumors. This study uses a single center, prospective, open label, randomized controlled clinical trial to explore the effects of preoperative application of intravenous isomaltose iron combined with erythropoietin and tranexamic acid compared to conventional treatment in patients with preoperative anemia or iron deficiency in bone tumor surgery, hoping to establish a standard paradigm for perioperative blood management in bone tumor patients.
