Stereotactic Spinal Radio surgery
The KIMS has established a Stereotactic Spinal Radiosurgery Program to treat patients with spinal metastases. Unique technology is used to deliver a high dose of radiation to the spinal tumor(s). Both benign and malignant (cancerous) metastases can be treated. Spinal radiosurgery is able to target the tumor very precisely, thereby minimizing the radiation dose to nearby normal structures. This highly selective radiation dose often results in effective pain and/or tumor control. The treatment can be as simple as one session given on an outpatient basis.
Pain relief is the primary use of stereotactic spine radiosurgery; more than 80% of patients achieve pain relief, often within a few days to weeks. The procedure also can be used as the first line of treatment against tumors, for treating any residual tumor left after surgery, as a radiation boost following conventional treatment, and as another option when other treatments haven't been successful.
Stereotactic spinal radiosurgery is a non-invasive procedure done on an outpatient basis and requires no recovery time. It often results in rapid pain control that can significantly and meaningfully improve your quality of life.
Gamma Knife radio surgery
For Gamma Knife radio surgery, a single one- to two-hour treatment is typically required, in which 201 beams of gamma rays are focused at multiple points throughout the target with the aim of matching the delivered radiation to the shape of the tumor.
Thus, the gamma radiation is concentrated in the tumor, and falloff in adjacent tissue is very steep, minimizing radiation to tissue lying in the entry or exit pathways. Because of this precise focusing ability, aggressive, high-dose gamma radiation can be delivered to stabilize, shrink, or destroy some lesions – even those deep in the cerebral hemispheres or brain stem.
The most common indication for Gamma Knife radiosurgery procedure is brain metastases, a condition that afflicts nearly a quarter of patients suffering from cancer. For the past several years, the most common indication of all Gamma Knife radiosurgery treatments at our center was for metastatic disease. The remaining percentage of Gamma Knife radiosurgery treatments were for primary and benign tumors, trigeminal neuralgia and arteriovenous malformations.
