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, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47).
Compared with conventional radiotherapy salvage, 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.
