Abstract: Provided herein are methods for decreasing the toxicity of advanced ablative cancer therapies on neighboring organs. The methods herein provide spacing between single or multiple tumor cites and immediate healthy organs while maintaining or increasing patient quality of life. Such toxicity isolation can be performed by inserting a spacer around the one or more tumor sites.

Abstract: Provided herein are methods for decreasing the toxicity of advanced ablative cancer therapies on neighboring organs. The methods herein provide spacing between single or multiple tumor cites and immediate healthy organs while maintaining or increasing patient quality of life. Such toxicity isolation can be performed by inserting a spacer around the one or more tumor cites, which can be performed concurrently with fiducial marker placement.
