How would you approach a patient with symptomatic spinal cord compression who is a poor surgical candidate and has a radio-resistant primary tumor?
Radiosurgical decompression of metastatic epidural spinal cord compression has been demonstrated (Ryu et al., PMID 20209611). In this report, significant decompression was achieved in 80% of the patients. This decompression is assessed in 2 months' MRI scan since radiosurgery takes time for tumor control. Thus, radiosurgery can be offered for patients without neurological deficits. A small rim of tumor facing the spinal cord may be looked at as underdosed? Or dosed? But any degree of decompression results in neurological improvement. Radioresistant tumors (renal cell ca, melanoma, sarcoma) were in the response group. Histology and grade of compression were not prognostic factors. Presence of neurologic symptoms was the single negative facto...

A definitive answer is difficult without understanding the severity and type of symptoms. Pain only would be quite different than if the patient has actively progressive myelopathy or circumferential tumor. Presumably, the diagnosis has been established as a radio-resistant tumor.
Also, it would help to know whether surgery was completely contraindicated, or just a major surgery requiring extensive resection and stabilization. If the patient were able to undergo a limited 'separation surgery', it could reduce the risk of neurologic progression and have less surgical complications than more aggressive surgical approaches. SBRT could then follow, as in this phase 2 study Ito et al., PMID 34715257.
