Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this single-center prospective randomized controlled trial is to test and compare the safety and effectiveness of autologous blood transfusion in spinal surgery for lung cancer spinal metastases. The main questions it aims to answer are:

* Does autologous blood transfusion increase the incidence of new metastases?
* Does autologous blood transfusion affect postoperative hemoglobin levels and the number of circulating tumor cells in the blood?
* Can autologous blood transfusion reduce the rate of allogeneic transfusion during and after surgery for spinal metastases?

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this study, participants underwent standard open spinal decompression surgery, and when blood transfusion was needed, autologous blood transfusion or allogeneic blood transfusion was used. Participants will be patients with lung cancer spinal metastases. Investigators will use flow cytometry, immunohistochemistry, and tumor cell culture methods to measure the number of circulating tumor cells in the blood before and after autologous blood transfusion.

Investigators will compare participants who receive autologous blood transfusion with those who do not to observe if there are differences in:

* The incidence of new metastases
* The rate of allogeneic transfusion during and after surgery
* Postoperative hemoglobin levels
* The number of circulating tumor cells in the blood
* The cost associated with transfusion

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Autoblood transfusion + leukocyte filter group

In our department open surgery is considered as the standard procedure. The patients underwent open surgery, with autologous blood transfusion combined with a leukocyte filter. Blood transfusion based on bleeding during surgery.

Group Type EXPERIMENTAL

Autoblood transfusion

Intervention Type PROCEDURE

Through a negative pressure suction device, the patient's blood that flows out during surgery is collected into a blood storage filter. During the suction process, it is mixed with an appropriate anticoagulant and passed through multiple layers of filters. When the volume of recovered blood reaches a certain level, it is continuously (or intermittently) centrifuged. Using a high-speed centrifugal blood recovery tank, the red blood cells are separated, and the plasma, waste, cell fragments, anticoagulants, and harmful components are diverted into a waste bag. A large amount of saline is used to repeatedly wash, purify, and concentrate the red blood cells. Finally, the concentrated red blood cells are prepared into a 70% red blood cell suspension with saline and stored in a collection bag for transfusion back to the patients. Open surgery is considered as the standard procedure for metastatic spinal cord compression

Allogeneic blood transfusion group

In our department open surgery is considered as the standard procedure. The patients receives open surgery with allogeneic blood transfusion. Blood transfusion based on bleeding during surgery.

Group Type NO_INTERVENTION
