Stereotactic Radiosurgery:
A new paradigm for post-radiotherapy relapse
There is accumulating evidence that stereotactic radiosurgery is a very effective option for patients with lesions that have relapsed after traditional radiotherapy, avoiding some of the problems associated with traditional radiotherapy or surgery (31-47).

Compared with conventional radiotherapy, radiosurgery creates a far more precise dose distribution and highly conformal therapeutic margin, much more effectively limiting the normal tissue exposure to excessive radiation. This allows a more biologically potent radiation application, creating a greater possibility for durable local control and long-term disease-free survival, compared with re-irradiation using conventional techniques.
