Synergy-S stereotactic radiosurgery for spinal tumors.

Abstract

BACKGROUND:

Radiation treatment of spinal and paraspinal tumors has been limited by the tolerance of the spinal cord. As such, therapeutic options are restricted to surgically accessible lesions or the use of suboptimal dosing of external beam irradiation.

OBJECTIVES:

To evaluate the safety and applicability of the Elekta Synergy-S radiation unit for the treatment of spinal tumors.

METHODS:

We retrospectively reviewed all patients treated with stereotactic radiosurgery for spinal tumors between November 2007 and June 2011.

RESULTS:

Thirty-four patients were treated for 41 lesions. Treatment indications were local tumor control and pain palliation. The mean follow-up was 10.8 +/- 11.6 months (range 0.5-38 months). No acute radiation toxicity or new neurological deficits occurred during the follow-up period. Local tumor control was achieved in 21 of the 24 lesions (87.5%) available for radiological follow-up at a median of 9.8 months (range 3-32 months). Good analgesia was achieved in 24/30 lesions (80%) that presented with intractable pain.

CONCLUSIONS:

The safety and feasibility of delivering single and multiple-fraction stereotactic spinal irradiation was demonstrated and became a standard treatment option in our institution.
