How do you balance target coverage vs cord constraints with spine SRS?

In general, balancing competing target coverage and OAR exposure considerations is always a risk/benefit proposition. Having a marginal failure where you sacrificed coverage to meet a constraint associated with a <5% complication rate is always cause for regret.

If a cord constraint cannot be met wi...

Overall, the challenges of balancing target volume coverage versus protection of OARs are the same in the treatment of spine SRS. I have generally recommended that target volume coverage not be too severely compromised to spare an OAR as failure to control the tumor will ultimately place that OAR at...
