High-Dose Proton/Photon RT + Surgery of Sarcomas of the Thoracic, Lumbar Spine/Sacrum

2014-07-24 14:19:17 | BioPortfolio


The purpose of this study is to test the effectiveness of high dose radiation administered by both proton and photon therapy. Radiation is an effective treatment for many types of tumors and it is thought that radiation alone, when given in much higher doses over a shorter period of time, may be more effective in controlling recurrence of sarcoma.


- In this study three types of radiation will be used: standard radiation (called photon); alternative form of radiation called proton beam therapy; and a localized radiation applicator plaque that can be applied to the surface of the dura (the fibrous outer envelope that surrounds the spinal cord and fluid surrounding the spinal cord) at time of surgical removal of the tumor.

- Radiation treatments (photon and proton) and possibly surgical removal of portions of the tumor with intraoperative radiation delivery to the surface dura with intraoperative radiation delivery will be performed over a period of 12 weeks. As part of the treatment planning process, participants will need two treatment planning CT scans and 2-3 treatment planning sessions.

- Participants will receive, in total, 39-43 photon/proton treatments.

Medical and Biotech [MESH] Definitions

An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.

The use of pre-treatment imaging modalities to position the patient, delineate the target, and align the beam of radiation to achieve optimal accuracy and reduce radiation damage to surrounding non-target tissues.

Computed tomography modalities which use a cone or pyramid-shaped beam of radiation.

Timing the acquisition of imaging data to specific points in the breathing cycle to minimize image blurring and other motion artifacts. The images are used diagnostically and also interventionally to coordinate radiation treatment beam on/off cycles to protect healthy tissues when they move into the beam field during different times in the breathing cycle.

The ability of some cells or tissues to withstand ionizing radiation without serious injury. Tolerance depends on the species, cell type, and physical and chemical variables, including RADIATION-PROTECTIVE AGENTS and RADIATION-SENSITIZING AGENTS.
