    International audienceUn élément fini de type layer-wise, une cinématique par couche, est proposé ici. Ce modèle comporte 5n champs cinématiques pour un multicouche à n couches. Cet article a pour but de présenter les récents développement de MPFEAP qui propose désormais, un module dynamique qui permet de calculer des modes propres et d'aborder des problèmes d'impact. Il permet également désormais la prise en compte d'interface non linéaires ou imparfaites

    A "one-day survey": as a reliable estimation of the potential recruitment for proton- and carbon- ion therapy in France.

    International audienceTo estimate the real figure of the potential patient recruitment for hadrontherapy we carried out a survey directly in 5 radiation therapy departments of the East of France as a "one-day survey". The results presented account for 77 cases of potential indications among 532 evaluated medical records

    Does gap-free intensity modulated chemoradiation therapy provide a greater clinical benefit than 3D conformal chemoradiation in patients with anal cancer?

    Abstract Background Chemoradiation is the standard treatment for anal cancer. 3D conformal radiotherapy (3D-CRT) is usually split in 2 sequences with a therapeutic break (gap) in between. Intensity-modulated radiation therapy (IMRT) makes it possible to reduce treatment time by abandoning this gap. The purpose of this study was to compare outcomes and toxicities in patients treated with either IMRT or 3D-CRT. Methods Between 2004 and 2011, the data of 51 patients treated with exclusive radiotherapy with or without concomitant chemotherapy for non-metastatic anal carcinoma were retrospectively analyzed. Twenty-seven patients were treated with 3D-CRT and 24 patients with IMRT, with a median dose delivered to the tumor of 59.4Gy [30.6-66.6], whatever the radiotherapy technique (p= 0.99). The median follow-up was 40 months [26.4-51.6]. Results There was no difference between the two groups for response to treatment (p= 0.46). Two-year overall survival, locoregional relapse-free survival and colostomy-free survival rates were 88.5%, 63% and 60.3%, respectively for the IMRT group and 81%, 76.5% and 81.1% for the 3D-CRT group (all NS). Ten patients (37%) in 3D-CRT and 11 patients (45.8%) in IMRT (p= 0.524) had grade 3 acute toxicity. No grade 4 toxicity occurred. Conclusions Our study suggests that further investigations concerning the use of IMRT to treat cancer of the anus are warranted. IMRT makes it possible to remove the gap, but with no impact on the prognosis. Nonetheless, a longer follow-up is essential to determine whether or not IMRT has an impact on late toxicity, local control and survival compared with conventional 3D-CRT.</p
