Outcome predicted by early tumor response from stereotactic radiosurgery

The response of a patient with metastatic brain tumors to treatment with stereotactic radiosurgery in the first six-to-twelve weeks can indicate whether follow-up treatments and monitoring are necessary, according to research conducted at the University of North Carolina.The study of 52 patients with metastatic brain legions, published in the January issue of the journal Neurosurgery, found that the tumors whose sizes decreased significantly after treatment with stereotactic radiosurgery (SRS) did not resume growth or require additional treatment.
