This multicenter RCT tested direct decompressive surgery plus radiotherapy against radiotherapy alone for metastatic epidural spinal cord compression (MESCC). The primary endpoint was the ability to walk after treatment. The trial was stopped early when interim analysis confirmed surgical superiority.
Prior surgical trials for MESCC used laminectomy, which removes posterior elements without touching the tumor — most metastases sit anterior to the cord in the vertebral body, so laminectomy decompresses nothing and destabilizes the spine. Those trials unsurprisingly showed no benefit over radiation, and surgery was largely abandoned.
This RCT established that circumferential direct decompression is the correct operation, and that performing it before radiation is critical.
When you see a surgical candidate with MESCC. Solid tumor, single compression level, not totally paraplegic for more than 48 hours, no radiosensitive histology (lymphoma, myeloma, leukemia, germ-cell tumor). The evidence supports surgery plus radiotherapy as initial treatment, not radiation with surgery held in reserve.
Do not adopt a radiation-first strategy: patients who fail radiation and cross over to salvage surgery walk again only 30% of the time, versus 62% when surgery is given first. The window for recovery closes while radiation is failing.
