GMV presents the new advances of radiance in the 11th Biennial ESTRO

 GMV, a multinational engineering firm successfully operating in various high technology markets and recognized as a highly innovative and competitive solution provider, is presenting in the 11th Biennial ESTRO meeting the new advances in radiance, the dedicated treatment planning system for Intra-Operative radiation therapy.

Intraoperative radiation therapy is a technique for targeting a large single radiation dose at the tumor bed during surgery, immediately after tumor removal (when the tumor is found to be unresectable, the IORT dose is used as a boost, with or without post-operative external beam RT). The radiation is focused directly on the anatomical area that contained the neoplasia, a possible location of sub-clinical disease or macroscopic residue.

The technical advantages of the IORT technique include direct visual control of the target volume and the possibility of protecting the surrounding healthy tissue, by simply moving or shielding it from the radiation beam. Electron beams can be delivered in a homogeneous dose at a controlled depth of the tissue layer of the tumor bed. Local control is always high and toxicity is greatly reduced.

The Report of AAPM’s Radiation Therapy Committee Task Group No. 72 of 2005 identified the need for treatment planning systems. Until the advent of radiance this was just not available in the market and today radiance is still the only solution.

Prof. Felipe Calvo, oncology department director of the Gregorio Marañón University Hospital, recently indicated that ‘the system enhances the documentation of the process for posterior analysis’.

Prof. Roberto Orecchia, radiotherapy division director of the European Institute of Oncology, has recently defined Radiance as an ‘important step forward in the history of IORT’, adding that ‘the preplanning phase is an important improvement in IORT treatment of breast cancer’.
