Comparing Two Target Volume Methods in Stereotactic Radiotherapy for Spinal Tumors

What this Trial Is About

Researchers are comparing two methods for defining the treatment area in stereotactic radiotherapy for patients with metastatic spinal tumors. This study aims to evaluate which target delineation method is better in terms of controlling the disease and reducing side effects. Approximately 500 patients with spinal tumors will participate in this bidirectional cohort study. Participants are divided into two groups based on how the treatment area is defined. Group 1 receives radiotherapy targeting only the local tumor, while Group 2s treatment area includes the local tumor plus the adjacent vertebral area. The study monitors these approaches to assess differences in treatment outcomes. During the study, patients will be followed up to assess disease control over two years and pain relief after three months. Side effects will also be tracked for two years. Participants will undergo imaging reviews and follow-up visits after radiotherapy to evaluate treatment effects and safety.
