En Bloc Resection Versus Separation Surgery Combined With Radiotherapy for the Treatment of Spinal Oligometastatic Tumor.

Summary

The purpose of this clinical trial is to explore the impact of En bloc surgery and separation surgery combined with radiation therapy on the prognosis and survival of patients with spinal oligometastatic cancer, describe the clinical results, and optimize future treatment goals
