Nouvelles approches en Radiothérapie

Radiotherapy (RT) is one of the most frequently used methods for cancer treatment (above 50% of patients will receive RT). Despite remarkable advancements, the dose tolerances of normal tissues continue being the main limitation in RT. Finding novel approaches that allow increasing normal tissue resistance is of utmost importance. This would make it possible to escalate tumour dose, resulting in an improvement in cure rate. Along this line, the team New Approaches in Radiotherapy (NARA) works on the exploration on novel  RT techniques.  NARA is a team pioneering the conception and development of innovative methods based on the use of the spatial fractionation of the dose. This strategy has already shown a remarkable reduction in side effects of the radiation.

Since we do not believe in frontiers, NARA was born with an interdisplinary and international character.  We work at the interphase between medical physics, computing (Monte Carlo simulations), and radiobiology.
