L’histoire du schwannome du nerf acoustique (SV) montre un déplacement du «standard de traitement» de la microchirurgie vers la radiothérapie. Pour ce type de tumeurs bénignes, le traitement a pour but d’éviter les complications fonctionnelles et de préserver la capacité auditive. Après microchirurgie pour une lésion de moins de 25 mm, on observera que le nerf facial est indemne dans approximativement 60% des cas et que la fonctionnalité du VIII est préservée dans 15% des cas pour des SV de plus de 15 mm et, dans 50% des cas, pour des SV de moins de 15 mm. Les différents progrès techniques et informatiques dans le domaine de la radiothérapie permettent aujourd’hui d’obtenir un taux de contrôle tumoral variant de 92 à 98% avec une morbidité quasi inexistante au niveau du nerf facial (<2%). La capacité auditive est maintenue dans approximativement 70% des cas. Forts de ces chiffres, on peut estimer que la prise en charge de ce type de tumeurs bénignes doit se faire par radiothérapie.

As a part of the clinical implementation of a kV cone-beam CT (CBCT) volumetric imaging system for new Elekta Synergy linear accelerators, the automatic image registration (IR) system of the XVI Software was studied. We examined the effect of the variability of matching parameters of the software on the results of the patient position errors. [less ▲]

Radiotherapy is a powerful continuously evolving effective treatment tool. Our aim is to offer the best treatments and assure security for patients and personnel. A proactive quality approach copied from the one implemented in the air transport industry has been established in our department. An Experience Feed Back Committee (EFBC) has been set up to identify, record and analyze systematically all reported precursor events. Our final objective is to test and strengthen the security of the organization and the quality of care for patients. [less ▲]

Background and Purpose: Dose escalation in order to improve the biochemical control in prostate cancer requires the application of irradiation techniques with high conformality. The dosimetric selectivity of three radiation modalities is compared: high-dose-rate brachytherapy (HDR-BT), intensity-modulated radiation radiotherapy (IMRT), and helical tomotherapy (HT). <br />Patients and Methods: Ten patients with prostate adenocarcinoma treated by a 10-Gy HDR-BT boost after external-beam radiotherapy were investigated. For each patient, HDR-BT, IMRT and HT theoretical treatment plans were realized using common contour sets. A 10-Gy dose was prescribed to the planning target volume (PTV). The PTVs and critical organs’ dose-volume histograms obtained were compared using Student’s t-test. <br />Results: HDR-BT delivers spontaneously higher mean doses to the PTV with smaller cold spots compared to IMRT and HT. 33% of the rectal volume received a mean HDR-BT dose of 3.86 ± 0.3 Gy in comparison with a mean IMRT dose of 6.57 ± 0.68 Gy and a mean HT dose of 5.58 ± 0.71 Gy (p < 0.0001). HDR-BT also enables to better spare the bladder. The hot spots inside the urethra are greater with HDR-BT. The volume of healthy tissue receiving 10% of the prescribed dose is reduced at least by a factor of 8 with HDR-BT (p < 0.0001). <br />Conclusion: HDR-BT offers better conformality in comparison with HT and IMRT and reduces the volume of healthy tissue receiving a low dose.
