The Safety and Efficacy of Autologous Transfusion in Spinal Surgery for Lung Cancer With Spinal Metastasis

Overview

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?

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
