From: Delayed postoperative radiotherapy increases the incidence of radiographic local tumor progression before radiotherapy and leads to poor prognosis in spinal metastases

Imaging of patients in progression before radiotherapy group (PBR). A 77-year-old man with T4 metastatic lung cancer experienced severe back pain and weakness for 2 months. a, b Sagittal and axial T2-weighted magnetic resonance imaging (MRI) before surgery showed a lesion in T4 with high-grade epidural spinal cord compression (ESCC). c Separation surgery was performed and postoperative radiograph indicated well fixation. d Postoperative axial T2-weighted MRI showing complete decompression of the spinal cord. Compared with postoperative image (e, 5 days after surgery), axial T2-weighted MRI showed local progression before radiotherapy (f, 50 days after surgery). The two images displayed the slices at the same level in T5 superior endplate
