Stereotactic radiotherapy and radiosurgery allow delivery of high irradiation doses in a limited volume. These techniques are specially adapted to brain and nervous pathologies. Indication are not only cancers and tumors but also non tumor tissues such as arteriovenous malformations. In some case purpose of stereotactic radiotherapy is solely functional, for example for trigeminal neuralgia. We detail the questions that raise treatment of these non-tumor pathologies. These pathologies imply a multidisciplinary approach that associate radiation oncologists, neuro-radiologist and neurosurgeons.

Management of oropharyngeal cancer depends on several factors. Immediate surgery or radiotherapy may be considered. If the patient is operable, the choice depends on the extent of the disease, the contributing factors, and the expected functional results. For HPV-positive cancers, studies show comparable efficacy between surgery and radiotherapy. For early-stage cancers, unimodal treatment should be preferred. For HPV-negative cancers, the results of retrospective and observational studies are in favor of surgery. These studies have some limitations. In observational and/or retrospective studies, reclassification biases and the applicability of propensity scores weaken the validity of studies showing differences in management. Tumor and patient comparability are others majors interpretation biases. It is precipitate to conclude that surgery is superior for HPV-negative oropharyngeal cancers. Toxicity, therefore, becomes a criterion of choice for treatment. Unimodal management by surgery allows limited toxicity for the early stages. Surgery has less impact on salivation. Radiotherapy is rather less deleterious for swallowing in the early stages. For the advanced stages of HPV-induced tumors, the non-superiority of surgery should lead to the choice of radiochemotherapy. For oropharyngeal cancers, the possible benefit of surgery in HPV-negative oropharyngeal cancers must be confirmed in randomized studies. For the early stages of oropharyngeal cancer with unimodal treatment, management could be decided by shared decision making.

Riassunto I carcinomi delle vie aerodigestive superiori (VADS) rappresentano l’ottavo cancro in termini di incidenza. Il trattamento allo stadio localizzato si basa principalmente sulla chirurgia. In alcuni casi, la chirurgia e integrata dalla radioterapia. A volte, il trattamento si basa su un’associazione di radioterapia e chemioterapia. Il posto della chemioterapia, allo stadio localizzato, e soprattutto associato alla radioterapia. La chemioterapia neoadiuvante con TPF (platino, 5-fluorouracile e docetaxel) non aumenta la sopravvivenza e deve essere riservata ad alcuni casi specifici. Allo stadio metastatico o ricorrente, il trattamento di riferimento si basa su una chemioterapia a base di platino ed erbitux, ma l’arrivo dell’immunoterapia modifica la sequenza di trattamento e, in questa indicazione, si sviluppano nuove terapie mirate, anche se restano solo allo stadio di sperimentazione terapeutica.

Resumen Los carcinomas de las vias aerodigestivas superiores (VADS) ocupan el octavo puesto en cuanto a incidencia entre los procesos oncologicos. El tratamiento en el estadio localizado consiste en la mayoria de los casos en la cirugia. En ocasiones, la cirugia se completa con la radioterapia. A veces, el tratamiento se basa en una asociacion de radioterapia y de quimioterapia. En los estadios localizados, la quimioterapia esta indicada sobre todo en asociacion con la radioterapia. La quimioterapia neoadyuvante con TPF (platino, 5-fluorouracilo y docetaxel) no aumenta la supervivencia y se debe reservar a ciertos casos particulares. En el estadio metastasico o recidivante, el tratamiento de referencia consiste en una quimioterapia basada en platino y erbitux, pero la aparicion de la inmunoterapia ha modificado la secuencia de tratamiento y las nuevas terapias dirigidas se estan abriendo un hueco en esta indicacion, aunque solo estan en el estadio de ensayos terapeuticos.

Resume Introduction Le trichoadenome est une tumeur folliculaire tres rare, mais dont l’aspect histopathologique est remarquable. Nous presentons dans cet article une serie de 12 cas de trichoadenome, ainsi que l’etude anatomoclinique et dermatoscopique d’un cas typique. Nous discutons ces resultats a la lumiere d’une recherche bibliographique exhaustive. Methodes Nous avons collecte 12 cas de trichoadenome de diagnostic incontestable, au laboratoire de dermatopathologie de la clinique dermatologique des hopitaux universitaires de Strasbourg, sur une periode de 30 ans (1989–2018). Resultats Les 12 cas concernaient 7 femmes et 5 hommes, d’âge moyen 58,9 ans, dont la majorite etaient localises sur l’extremite cephalique puis la fesse et la cuisse. L’examen histopathologique, similaire pour les 12 cas, montrait de multiples kystes de structure epidermoide contenant une keratine lamellaire eosinophile avec une paroi stratifiee, sans tige pilaire, situes dans le derme superficiel et moyen et semblant s’empiler les uns sur les autres. En immunohistochimie, les marqueurs de keratines large spectre etaient toujours positifs, le marqueur folliculaire Ber-EP4 faiblement exprime et PHLDA1 negatif. Pour le cas examine en dermatoscopie a lumiere polarisee, des petites aires arrondies blanc-jaune correspondant aux structures kystiques, entourees de vaisseaux lineaires irreguliers, etaient observees. Discussion Le trichoadenome est une tumeur rare de l’adulte d’âge moyen 45 ans, sans predominance de sexe. Il est asymptomatique, a croissance lente, de couleur variable, de taille infracentimetrique et localise le plus souvent au visage ou sur les fesses. Sur le plan histologique, la juxtaposition de multiples petites structures kystiques plaide pour une origine folliculaire. Le diagnostic differentiel se fait avec le trichoblastome qui exprime toujours intensement PHLDA1 et/ou Ber-EP4, le trichoepitheliome desmoplastique constitue de multiples travees beaucoup plus fines dans un stroma tres fibreux avec des vaisseaux arborescents bien nets sur un arriere-fond blanc-jaune ivoire en dermatoscopie, le carcinome microkystique qui a une extension plus profonde et le milium en plaque ou les kystes sont plus volumineux.

Genetic studies of familial forms of interstitial lung disease (ILD) have led to the discovery of telomere-related gene (TRG) mutations (TERT, TERC, RTEL1, PARN, DKC1, TINF2, NAF1, NOP10, NHP2, ACD, ZCCH8) in approximately 30% of familial ILD forms. ILD patients with TRG mutation are also subject to extra-pulmonary (immune-hematological, hepatic and/or mucosal-cutaneous) manifestations. TRG mutations may be associated not only with idiopathic pulmonary fibrosis (IPF), but also with non-IPF ILDs, including idiopathic and secondary ILDs, such as hypersensitivity pneumonitis (HP). The presence of TRG mutation may also be associated with an accelerated decline of forced vital capacity (FVC) or poorer prognosis after lung transplantation, notwithstanding which, usual ILD treatments may be proposed. Lastly, patients and their relatives are called upon to reduce their exposure to environmental lung toxicity, and are likely to derive benefit from specific genetic counseling and pre-symptomatic genetic testing.

Introduction et but de l’etude Les nausees sont des symptomes frequents chez les patients irradies pour des lesions cerebrales. Le complexe vagal dorsal constitue de l’area postrema, du noyau du tractus solitaire et du noyau moteur dorsal du nerf vague situe dans le tronc cerebral a ete identifie comme etant le centre des nausees et vomissements. L’objectif de notre etude etait de determiner une correlation entre la dose delivree dans le complexe vagal dorsal et la survenue de nausees ou de vomissements chez les patients irradies pour des tumeurs cerebrales benignes. Materiel et methodes Entre decembre 2017 et janvier 2021, 102 patients consecutifs ont ete pris en charge pour des tumeurs cerebrales benignes au CHU de Bordeaux par archtherapie volumetrique modulee normofractionnee. La delineation du complexe vagal dorsal a ete realisee sur l’IRM cerebrale, en sequence T1 avec injection de gadolinium, fusionnee a la scanographie de centrage, a l’aide de l’atlas de Beddok et al. Un controle de la qualite de la delineation a ete realise pour les dix premiers dossiers par cinq radiotherapeutes, dont l’auteur du referentiel de delineation, avec analyse de l’indice Kappa. Les symptomes de nausees et les traitements antinauseeux ont ete recueillis lors des consultations hebdomadaires pendant la radiotherapie. Les criteres dosimetriques (dose maximale, dose moyenne, dose dans 0,03 cm3, volumes recevant 10, 20, 25, 30, 35, 40 ou 50 Gy [V10, V20, V25, V30, V35, V40, V50]) ont ete recueillis pour le complexe vagal dorsal, le tronc cerebral et le cerveau, et compares entre les groupes de patients souffrant ou non de nausees. Resultats et analyse statistique Sur 102 patients, 40 ont souffert de nausees (soit 39 %), necessitant un traitement antinauseeux pour 23 d’entre eux (soit 58 %). Dans le groupe de patients souffrant de nausees, le volume de complexe vagal dorsal et tronc cerebral irradie etait significativement plus important pour tous les parametres recueillis sauf le V50 ( Tableau 1 ) comparativement aux patients asymptomatiques. Il n’y avait pas de difference significative pour les criteres dosimetriques du cerveau. Les meilleurs criteres predictifs de la survenue de nausees sont rapportes dans le Tableau 2 . L’indice de Kappa etait de 0,6,7 soit un accord modere sur les contours du complexe vagal dorsal, pour un volume moyen de 0,13 cm3. Conclusion La dose recue dans le complexe vagal dorsal etait significativement associee a la survenue de nausees. Plusieurs criteres dosimetriques ont ete identifies qui pourraient definir des contraintes de dose dans le complexe vagal dorsal, a valider par une etude prospective. Le complexe vagal dorsal est une petite sous-structure du tronc cerebral, avec un risque de variation dans sa delineation, necessitant un apprentissage.

Purpose Endoscopic endonasal surgery (EES) is becoming a standard for most malignant sinonasal tumours. Margin analysis after piecemeal resection is complex and optimally relies on accurate histosurgical mapping. Postoperative radiotherapy may be adapted based on margin assessment mapping to reduce the dose to some sinonasal subvolumes. We assessed the use of histosurgical mapping by radiation oncologists (RO). Material and methods A French practice survey was performed across 29 ENT expert RO (2 did not answer) regarding integration of information on EES, as well as quality of operative and pathology reportsto refine radiotherapy planning after EES. This was assessed through an electronic questionnaire. Results EES was ubiquitously performed in France. Operative and pathology reports yielded accurate description of EES samples according to 66.7% of interviewed RO. Accuracy of margin assessment was however insufficient according to more than 40.0% of RO. Additional margins/biopsies of the operative bed were available in 55.2% (16/29) of the centres. In the absence of additional margins, quality of resection after EES was considered as microscopically incomplete in 48.3% or dubious in 48.3% of RO. As performed, histosurgical mapping allowed radiotherapy dose and volumes adaptation according to 26.3% of RO only. Conclusions Standardized histosurgical mapping with margin and additional margin analysis could be more systematic. Advantages of accurate EES reporting could be dose painting radiotherapy to further decrease morbidity in sinonasal tumours.

French regulations about research ethics are based on the so-called Jarde law, which defines researches involving human beings. Researches involving human beings require the submission of research protocols to a committee for protection of persons with a precise list of documents to submit for a favourable opinion. This law describes different categories of researches and determines the ethical procedures to apply before setting up a research protocol. This issue of categorisation is central and must be taken into account by researchers from the beginning of the research process. Researches considered as not involving human beings also require a set of ethical precautions focused on patients' information and the collection of their non-opposition (due to the application of the General Data Protection Regulation adopted by the European Parliament). Thus, many regulations exist and they require a real work for researchers to meet these requirements in research ethics. This article aims to summarise French regulations. Selected examples are specifically taken into the field of radiation oncology research.

Objectives Environmental contamination by patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) through respiratory droplets suggests that surfaces and equipment could be a medium of transmission. We aimed to assess the surface and equipment contamination by SARS-COV-2 of an emergency department (ED) during the coronavirus infectious disease-2019 (COVID-19) outbreak. Methods We performed multiple samples from different sites in ED patients care and non-patient care areas with sterile premoistened swabs and used real-time reverse transcriptase polymerase chain reaction (RT-PCR) to detect the presence of SARS-CoV-2 ribonucleic acid (RNA). We also sampled the personal protective equipment (PPE) from health care workers (HCWs). Results Among the 192 total samples, 10 (5.2%) were positive. In patient care areas, 5/46 (10.9%) of the surfaces directly in contact with COVID-19 patients revealed the presence of SARS-CoV-2 RNA, and 4/56 (7.1%) of the surfaces that were not directly in contact with COVID-19 patients were positive. SARS-CoV-2 RNA was present only in the patients’ examination and monitoring rooms. Before decontamination SARS-CoV-2 RNA was present on the saturation clip, the scuff for blood pressure measurement, the stretcher, the plastic screens between patients and the floor. After decontamination, SARS-CoV-2 RNA remained on the scuff, the stretcher and the trolleys. All samples from non-patient care areas or staff working rooms were negative. Only one sample from the PPE of the HCWs was positive. Conclusions Our findings suggest that surfaces and equipment contamination by SARS-CoV-2 RNA in an ED during the COVID-19 outbreak is low and concerns exclusively patients’ examination and monitoring rooms, preserving non-patient care areas.

Objectives The aim was to assess the incidence of sink contamination by multidrug-resistant (MDR) Pseudomonas aeruginosa and Enterobacteriaceae, risk factors for sink contamination and splashing, and their association with clinical infections in the intensive care setting. Methods A prospective French multicentre study (1 January to 30 May 2020) including in each intensive care unit (ICU) a point-prevalence study of sink contamination, a questionnaire of risk factors for sink contamination (sink use, disinfection procedure) and splashing (visible plashes, distance and barrier between sink and bed), and a 3-month prospective infection survey. Results Seventy-three ICUs participated in the study. In total, 50.9% (606/1191) of the sinks were contaminated by MDR bacteria: 41.0% (110/268) of the sinks used only for handwashing, 55.3% (510/923) of those used for waste disposal, 23.0% (62/269) of sinks daily bleached, 59.1% (126/213) of those daily exposed to quaternary ammonium compounds (QACs) and 62.0% (285/460) of those untreated; 459 sinks (38.5%) showed visible splashes and 30.5% (363/1191) were close to the bed ( Discussion Our data showed frequent and multifactorial infectious risks associated with contaminated sinks in ICUs.

French regulations about research ethics are based on the so-called Jardé law, which defines researches involving human beings. Researches involving human beings require the submission of research protocols to a committee for protection of persons with a precise list of documents to submit for a favourable opinion. This law describes different categories of researches and determines the ethical procedures to apply before setting up a research protocol. This issue of categorisation is central and must be taken into account by researchers from the beginning of the research process. Researches considered as not involving human beings also require a set of ethical precautions focused on patients' information and the collection of their non-opposition (due to the application of the General Data Protection Regulation adopted by the European Parliament). Thus, many regulations exist and they require a real work for researchers to meet these requirements in research ethics. This article aims to summarise French regulations. Selected examples are specifically taken into the field of radiation oncology research.

Trichoadenoma is a very rare follicular tumour with a remarkable histopathological appearance. In this article we present a series of 12 cases of trichoadenoma, as well as the anatomoclinical and dermatoscopic findings in a typical case. We discuss these findings in the light of an extensive literature research.We collated 12 cases of trichoadenoma of indisputable diagnosis made at the dermatopathology laboratory of the Dermatological Clinic of the University Hospitals of Strasbourg over a 30-year period (1989-2018).The 12 cases comprised 7 women and 5 men, of average age 58.9 years, the majority having lesions on the cephalic extremity followed by the buttocks and thighs. Histopathological examination, which was similar in all 12 cases, showed multiple epidermal cysts containing an eosinophil lamellar keratin with a stratified wall without any visible hair, located in the superficial and mid dermis and appearing to be stacked on top of one another. In immunohistochemistry, broad spectrum keratin markers were still positive, the follicular marker Ber-EP4 weakly expressed and PHLDA1 was negative. For the case examined using polarized-light dermatoscopy, small rounded white-yellow areas were observed corresponding to cystic structures surrounded by irregular linear vessels.Trichoadenoma is a rare tumour seen in middle-aged adults of mean age 45 years, and has no sexual predominance. It is asymptomatic, slow-growing, variable in colour, measures less than one centimeter and is most often located on the face or buttocks. In terms of histology, the juxtaposition of multiple small cystic structures suggests a follicular origin. Differential diagnosis is made with trichoblastomas, which always intensely express PHLDA1 and/or Ber-EP4, desmoplastic trichoepithelioma, which consists of multiple much thinner spans in a highly fibrous stroma with clearly visible arborescent vessels over a white-yellow ivory background at dermatoscopy, microcystic carcinoma, which has a deeper extension, and plaque milium, in which the cysts are larger.

Most of the benign intracranial tumors are meningiomas, vestibular schwannomas, pituitary adenomas, craniopharyngiomas, and glomus tumors. Some of them grow very slowly, and can be observed without specific treatment, especially if they are asymptomatic. Symptomatic or growing tumors are treated by surgery, which is the reference treatment. When surgery is not possible, due to the location of the lesion, or general conditions, radiotherapy can be applied, as it is if there is a postoperative growing residual tumor, or a local relapse. Indications have to be discussed in polydisciplinary meetings, with precise evaluation of the benefit and risks of the treatments. The techniques to be used are the most modern ones, as multimodal imaging and image-guided radiation therapy. Stereotactic treatments, using fractionated or single doses depending on the size or the location of the tumors, are commonly realized, to avoid as much a possible the occurrence of late side effects.

Resume Objectif de l’etude L’irradiation du sein apres tumorectomie est le standard pour le cancer du sein invasif. Des etudes randomisees montrent que la radiotherapie hypofractionnee est equivalente chez des patients selectionnes. Cette etude s’est interessee a l’evolution des pratiques dans un centre de lutte contre le cancer et analyse son impact economique. Materiel et methode Toutes les prescriptions pour cancer du sein invasif entre janvier 2010 et juin 2014 ont ete analysees. Les patientes d’au moins 60 ans, atteintes de cancer classe pN0, n’ayant pas ete irradiees dans les aires ganglionnaires, sans indication de boost, ont ete incluses dans l’etude economique. L’etude des pratiques a exclu celles incluses dans des essais cliniques, ou atteintes de tumeur de haut grade. Le cout des transports a ete estime grâce aux donnees de la Caisse primaire d’assurance maladie (CPAM) Resultats Deux mille trente et une patientes ont recu un traitement, 399 etaient eligibles pour l’etude economique (20 %) et 282 pour celle des pratiques (14 %). La proportion de traitement en 25 fractions a diminue de 90 % a 16 % au premier semestre 2014. A contrario, les traitements en 15 ou 16 fractions ont augmente de 6 % en 2010 a 68 % debut 2014. La proportion de traitements hypofractionnes est passee de 100 % de 42,5 Gy en 16 seances en 2010 a 100 % de 40 Gy en 15 seances en 2014, s’adaptant a l’actualisation des essais Standardisation of Breast Radiotherapy (START) britanniques. Le traitement en cinq seances etait stable autour de 7 % (4 a 16 %), reserve pour les patientes de plus de 80 ans (p Conclusion L’hypofractionnement peut concerner environ 20 % des patients. Cela permettrait de diminuer l’investissement personnel du patient dans son traitement et d’epargner 2327 € par traitement pour la societe.

Alternative and complementary medicine is defined as any substance or technique of non-allopathic medicine used to improve health and quality of life. The purpose of this prospective observational study was to evaluate the use of alternative and complementary medicine during radiotherapy.A questionnaire was given the last week of treatment to all patients treated for breast cancer, prostate cancer or head and neck cancer in our centre in 2016.In 2016, 132 patients were included. Fifty-seven patients (43%) used alternative and complementary medicine during radiotherapy, more women (61%) than men (35%) (P=0.005). The use of alternative and complementary medicine varied according to locations: 44% of head and neck cancers, 57% of breast cancers and 24% of prostate cancers, but sex was the confounding factor. If alternative and complementary medicine was used before radiotherapy, 82% of patients used it during treatment, compared to 30% if they were naive (P10Alternative and complementary medicines are used more by women, and by patients who used them before radiotherapy. The desired effects are mainly to reduce the side effects of the treatments. More than 80% of patients, whether or not they use alternative and complementary medicine, demand medical information.

Locally advanced oesophageal cancer treatment requires a multidisciplinary approach with the combination of chemotherapy and radiotherapy for preoperative and definitive strategy. Preoperative chemoradiation improves the locoregional control and overall survival after surgery for locally advanced oesophageal cancer. Definitive chemoradiation can also be proposed for non-resectable tumours or medically inoperable patients. Besides, definitive chemoradiation is considered as an alternative option to surgery for locally advanced squamous cell carcinomas. Chemotherapy regimen associated to radiotherapy consists of a combination of platinum derived drugs (cisplatinum or oxaliplatin) and 5-fluorouracil or a weekly scheme combination of carboplatin and paclitaxel according to CROSS protocol in a neoadjuvant strategy. Radiation doses vary from 41.4Gy to 45Gy for a preoperative strategy or 50 to 50.4Gy for a definitive treatment. The high risk of lymphatic spread due to anatomical features could justify the use of an elective nodal irradiation when the estimated risk of microscopic involvement is higher than 15% to 20%. An appropriate delineation of the gross tumour volume requires an exhaustive and up-to-date evaluation of the disease. Intensity-modulated radiation therapy represents a promising approach to spare organs-at-risk. This critical review of the literature underlines the roles of radiotherapy for locally advanced oesophageal cancers and describes doses, volumes of treatment, technical aspects and dose constraints to organs-at-risk.

Induction chemotherapy (IC) with TPF (docetaxel, cisplatin, 5FU) for locally advanced head and neck squamous cell carcinoma (LAHNSCC) is limited to fit patients. We conducted a retrospective cohort study to assess the use of the EXTREME regimen (platinum-based therapy, 5FU, cetuximab) as IC in frail patients with LAHNSCC. Retrospective analysis of all consecutive patients with unresectable LAHNSCC treated with the EXTREME regimen, with or without 5FU as IC, from two French centers from 2008 to 2015. We assessed the rate of completed sequence defined as at least two cycles of IC and definitive radiation therapy. We included 34 patients with a median age of 56 years [44-70]. The primary site of tumor development was the oropharynx (67%, n=23, all HPV negative), hypopharynx (21%, n=7) and the oral cavity (12%, n=4). At inclusion, patients presented: T4 76, 5% (n=26), N2c 41% (n=14), N3 26% (n=9), stage disease IVa 62% (n=21), IVb 38% (n=13), ECOG PS2 38% (n=13), decreased weight (10% in one month or 15% in 6 months) 74% (n=25). The sequence was achieved for 76% (n=26) of patients and 80% (n=27) presented a clinical response after the chemotherapy course with notably increased weight (40%, n=11) or general status (75%, n=26). Median PFS and OS were 5.7 and 15.5 months, respectively. Disease progression at 3 months was significantly associated with decreased median overall survival (13.6 versus 21.9 months, p=0.01). This is the first study to report the use of the EXTREME regimen as induction chemotherapy, and although this IC was used in a very frail population, the majority completed the sequence with significant clinical benefit.

Background Homeostatic turnover of the extracellular matrix conditions the structure and function of the healthy lung. In lung transplantation, long-term management remains limited by chronic lung allograft dysfunction, an umbrella term used for a heterogeneous entity ultimately associated with pathological airway and/or parenchyma remodeling. Objective This study assessed whether the local cross-talk between the pulmonary microbiota and host cells is a key determinant in the control of lower airway remodeling posttransplantation. Methods Microbiota DNA and host total RNA were isolated from 189 bronchoalveolar lavages obtained from 116 patients post lung transplantation. Expression of a set of 11 genes encoding either matrix components or factors involved in matrix synthesis or degradation (anabolic and catabolic remodeling, respectively) was quantified by real-time quantitative PCR. Microbiota composition was characterized using 16S ribosomal RNA gene sequencing and culture. Results We identified 4 host gene expression profiles, among which catabolic remodeling, associated with high expression of metallopeptidase-7, -9, and -12, diverged from anabolic remodeling linked to maximal thrombospondin and platelet-derived growth factor D expression. While catabolic remodeling aligned with a microbiota dominated by proinflammatory bacteria (eg, Staphylococcus, Pseudomonas, and Corynebacterium), anabolic remodeling was linked to typical members of the healthy steady state (eg, Prevotella, Streptococcus, and Veillonella). Mechanistic assays provided direct evidence that these bacteria can impact host macrophage-fibroblast activation and matrix deposition. Conclusions Host-microbes interplay potentially determines remodeling activities in the transplanted lung, highlighting new therapeutic opportunities to ultimately improve long-term lung transplant outcome., Graphical abstract

International audience; A finite fracture approach based on the Coupled Criterion is used to analyze multi-cracking in a woven ceramic matrix composite. In-situ micrographic observations obtained during tensile and bending tests performed on chemical vapor infiltrated SiC/SiC samples are utilized to identify cracking mechanisms. A two dimensional finite element model is generated to approximate the actual specimen section geometry including matrix, fiber tows and porosity. Numerical simulations are carried out with a dedicated algorithm to simulate nucleation and propagation of cracks. Comparing the simulation results with experimental ones shows that the model captures the main cracking features.

Introduction et but de l’etude Le but de ce travail etait d’evaluer l’efficacite et la tolerance de la radiotherapie stereotaxique des oligometastases surrenaliennes au centre hospitalier universitaire de Bordeaux. Materiel et methodes De janvier 2013 a mars 2019, 15 patients d’âge median 61 ans (extremes : 47–81 ans) ont ete traites par irradiation stereotaxique pour des metastases surrenaliennes secondaires a un cancer primitif bronchique (81 %) ou colique (19 %). Tous avaient au plus quatre sites metastatiques. Treize patients ont ete pris en charge sur un accelerateur lineaire VersaHD-Elekta®, un sur Synergy-Elekta® et un sur CyberKnife-Accuray®. Les doses delivrees variaient de 20 a 48 Gy en deux a quatre fractions avec une dose mediane totale de 24 Gy en trois fractions (dose biologique effective (BED) de 43,2 Gy avec un rapport α/β surrenale de 10 Gy). Le controle local a ete evalue par la methode de Kaplan-Meier. La toxicite a ete estimee selon les Common Terminology Criteria for Adverse Events (CTCAE)v4.0. Resultats et analyse statistique Le suivi median etait de 14,5 mois. La duree mediane de controle local etait de 6 mois (extremes : 2–66 mois) avec des taux de controle local de 50 %, 37,8 % et 5,6 % a respectivement 6 mois, 1 an et 2 ans. Aucun patient n’a souffert de toxicite de grade 3 ou plus. Une toxicite aigue de grade 2 ou moins a ete notee pour 50 % des patients : asthenie, diarrhees, nausees, douleurs abdominales, ulcere gastrique. Une toxicite tardive de grade 2 est survenue chez 25 % des patients : epigastralgies, ulcere gastrique, insuffisance surrenale, lombalgies. Conclusion D’apres notre retour d’experience sur 15 patients traites avec une dose mediane de 24 Gy en trois fractions, la tolerance de la radiotherapie stereotaxique surrenalienne est satisfaisante. Les resultats de controle local semblent inferieurs aux resultats de la litterature, plaidant pour une escalade de dose (objectif de BED ≥ 85 Gy).

Resume Les cancers de l’œsophage localement evolues relevent d’une prise en charge pluridisciplinaire ou la chimioradiotherapie occupe une place essentielle. La chimioradiotherapie neoadjuvante permet d’ameliorer les taux de controle locoregional et de survie globale des cancers de l’œsophage localement evolues operes. La chimioradiotherapie exclusive a egalement une place pour les lesions non resecables et/ou pour les patients non operables et est consideree comme une alternative a la chirurgie dans la prise en charge initiale des carcinomes epidermoides de l’œsophage localement evolues. La chimiotherapie associee consiste en une combinaison de sels de platine (cisplatine ou oxaliplatine) et de 5-fluoro-uracile le plus souvent, ou de carboplatine et de paclitaxel hebdomadaire selon le protocole CROSS en situation neoadjuvante. Les doses varient de 41,4 Gy (protocole CROSS) a 45 Gy en situation neoadjuvante. En traitement exclusif, une dose de 50 a 50,4 Gy est preconisee selon les recommandations francaises et americaines. Les volumes cibles tiennent compte des particularites anatomiques de l’œsophage et de son drainage lymphatique. Ainsi, une irradiation ganglionnaire prophylactique interesse classiquement les aires ganglionnaires presentant un risque d’envahissement de plus de 15 % a 20 %. L’utilisation de la radiotherapie conformationnelle avec modulation d’intensite represente une approche prometteuse susceptible de diminuer la toxicite dans les organes a risque adjacents. Cet article decrit, a partir d’une revue critique de la litterature, la place de la chimioradiotherapie dans la strategie therapeutique, les volumes anatomiques d’interet, les doses de prescription, les contraintes de doses dans les organes a risque et les techniques de radiotherapie adaptees.

Purpose We aimed to identify the most accurate combination of phantom and protocol for image value to density table (IVDT) on volume-modulated arc therapy (VMAT) dose calculation based on kV-Cone-beam CT imaging, for head and neck (H&N) and pelvic localizations. Methods Three phantoms (Catphan ® 600, CIRS ® 062M (inner phantom for head and outer phantom for body), and TomoTherapy ® “Cheese” phantom) were used to create IVDT curves of CBCT systems with two different CBCT protocols ( Standard-dose Head and Standard Pelvis ). Hounsfield Unit (HU) time stability and repeatability for a single On-Board-Imager (OBI) and compatibility of two distinct devices were assessed with Catphan ® 600. Images from the anthropomorphic phantom CIRS ATOM ® for both CT and CBCT modalities were used for VMAT dose calculation from different IVDT curves. Dosimetric indices from CT and CBCT imaging were compared. Results IVDT curves from CBCT images were highly different depending on phantom used (up to 1000 HU for high densities) and protocol applied (up to 200 HU for high densities). HU time stability was verified over seven weeks. A maximum difference of 3% on the dose calculation indices studied was found between CT and CBCT VMAT dose calculation across the two localizations using appropriate IVDT curves. One IVDT curve per localization can be established with a bi-monthly verification of IVDT-CBCT. Conclusions The IVDT-CBCT CIRS-Head phantom with the Standard-dose Head protocol was the most accurate combination for dose calculation on H&N CBCT images. For pelvic localizations, the IVDT-CBCT Cheese established with the Standard Pelvis protocol provided the best accuracy.

Resume Objectif de l’etude Un masque utilise pour la radiotherapie peut paraitre contraignant et anxiogene. Le but de ce travail etait donc d’evaluer l’anxiete liee au masque ainsi que les strategies d’adaptation (ou coping) mises en place par les patients. Patients et methodes Dix-neuf patients, irradies avec un masque pour un cancer ORL, une tumeur cerebrale ou un lymphome, ont ete vus par la meme psychologue a deux reprises pendant leur traitement, soit lors de la confection du masque et de la premiere seance de radiotherapie, soit en milieu et fin de traitement. Trente-quatre entretiens semi-directifs ont ete traites par une analyse thematique de contenu et 13 patients ont repondu a l’echelle State-Trait Anxiety Inventory (STAI-YB) mesurant l’anxiete etat et au questionnaire Ways of Coping Checklist (WCC) evaluant les strategies de coping. Resultats Avec des moyennes comprises entre 26 et 31, les scores d’anxiete relative au masque ont ete faibles tout au long du traitement, ce qui a ete corrobore par les propos recueillis lors des entretiens semi-directifs. Une representation positive du masque (de type « ami » ou « protection ») a ete retrouvee pour 12 patients, pouvant expliquer ce faible niveau d’anxiete. La quasi-totalite des patients (12 sur 13) a utilise des strategies de coping centrees sur le probleme. Conclusion L’anxiete relative au masque est faible. Certains patients construisent une representation positive du masque. Les explications fournies par les professionnels de sante sur le masque peuvent favoriser ces representations.

Objectif de l’etude Les adenopathies cervicales du carcinome primaire inconnu divisent la communaute medicale entre ceux qui favorisent l’irradiation elective unilaterale et ceux qui preconisent l’irradiation bilaterale du cou. Nous voulions evaluer les controles locaux et regionaux et la toxicite apres irradiation cervicale bilaterale ou unilaterale. Materiel et methode Il s’agit d’une etude de cohorte multicentrique retrospective. Les patients atteints de carcinome primaire inconnu sans metastases distantes traites par une irradiation externe entre 2000 et 2015 ont ete inclus. Les patients ont fait l’objet d’un suivi regulier. Resultats Sur les 350 patients de 20 centres selectionnes, 39 (11,5 %) etaient atteints d’un cancer de stade N1, 70 (20,7 %) N2a, 117 (34,5 %) N2b, 24 (7,1 %) N2c et 89 (26,3 %) N3, 222 (70,9 %) d’un ou de plusieurs ganglion(s) en rupture capsulaire, 259 (74,4 %) patients ont eu un curage cervical, 350 (100 %) une irradiation cervicale, dont 61 (17,4 %) unilaterale et 304 (87,6 %) une irradiation des muqueuses. Trente-quatre (9,8 %) et 217 (62,2 %) patients ont ete pris en charge par chimiotherapie respectivement neoadjuvante et concomitante. Le suivi median etait de 37 mois (Ecart interquartile : 24 ; 63). Sur 3 ans, les taux de rechute locale, regionale et locoregionale etaient respectivement de 5,6 % [3,0–8,1], 11,7 % [8,1–15,2] et 15,0 % [10,9–18,8]. Les probabilites de survie globale sur trois ans et de survie specifique etaient respectivement de 80,6 % [75,5–84,8] et 84,7 % [80,6–89,1]. Dans l’analyse multifactorielle, 1) l’irradiation des muqueuses etait le seul facteur pronostique associe a un meilleur taux de controle local ; 2) la dissection du cou, le stade ≥ N2b et l’interruption de la radiotherapie de ≥ 4 jours etaient associes a un moins bon taux de controle regional ; et 3), la TEP-scanographie, le plus grand diametre N, le stade ≥ N2b, l’interruption de la radiotherapie et la chimiotherapie neoadjuvante ont ete associes a une survie specifique plus courte. Conclusion L’irradiation bilaterale semble etre plus efficace sur le controle des tumeurs mais notre etude manque de puissance.

Objectif de l’etude Les maladies coronariennes representent une complication tardive severe de la radiotherapie des cancers du sein gauche. Cependant, il n’y a pas de contraintes de dose validees sur les coronaires. L’objectif de cette etude etait de determiner si la delineation des arteres coronaires, en l’absence de contraintes specifiques, a eu un impact dosimetrique comparativement a la delineation du cœur seul. Materiel et methode Cette etude monocentrique realisee entre novembre 2017 et fevrier 2018 a inclus 20 patientes atteintes d’un cancer du sein gauche traite par irradiation adjuvante. Nous avons compare les dosimetries tridimensionnelles du volume de sein irradie a 50 Gy prenant en compte la delineation du cœur seul, avec celles prenant en compte la delineation du cœur et des arteres coronaires (dosi-coro). Les dosimetries ont ete realisees par deux physiciens differents, avec respect d’une dose moyenne dans le cœur de moins de 5 Gy. Les parametres suivants ont ete etudies : dose maximale et dose moyenne dans les coronaires, l’indice de conformite, le volume recevant 95 % de la dose (V95 %) du volume cible anatomoclinique (CTV). Resultats La moyenne de la dose maximale dans les arteres coronaires etait de 12,69 Gy [41,93–1,29 Gy] en prenant en compte la delineation du cœur et des arteres coronaires contre 23,83 Gy [49,38–3,59 Gy] en prenant en compte la delineation du cœur seul (p = 0,019). La moyenne de la dose moyenne dans les arteres coronaires etait de 2,87 Gy [5,4–0,85 Gy] en prenant en compte la delineation du cœur et des arteres coronaires contre 3,75 Gy [6,8–1,09 Gy] en prenant en compte la delineation du cœur seul (p = 0,10). La qualite de la dosimetrie etait identique dans les deux groupes avec une dose moyenne dans le cœur de moins de 5 Gy. La couverture du volume cible anatomoclinique n’etait pas differente, que l’on prenne en compte ou non la delineation des arteres coronaires. Conclusion La delineation des arteres coronaires, sans specification de contraintes, influence la dosimetrie avec une diminution significative de la dose maximale dans les coronaires sans modification de la couverture au volume cible anatomoclinique.

Objectif de l’etude Plusieurs etudes precliniques suggerent qu’en stimulant l’immunite, la radiotherapie pourrait permettre une augmentation de l’efficacite de l’immunotherapie. Les donnees cliniques confirmant cette hypothese restent rares. Nous avons voulu comparer retrospectivement, chez des patients irradies et non irradies, la tolerance et les survies sans progression et globale apres une immunotherapie de premiere ligne par ipilimumab pour un melanome metastatique exprimant BRAF non mute. Materiel et methode Nous avons recueilli retrospectivement les donnees cliniques et de radiotherapie de tous les patients consecutifs atteints de melanome non-BRAF mute traites par ipilimumab (premiere ligne metastatique) au centre hospitalier universitaire de Bordeaux. La radiotherapie etait indiquee pour le traitement d’une ou plusieurs metastases ou en situation adjuvante. Les donnees de toxicite (grade 3 ou plus) et de survie ont ete comparees entre les patients traites par irradiation avant ou pendant le traitement par ipilimumab et les patients non irradies. Resultats Parmi 51 patients traites par ipilimumab en premiere ligne entre fevrier 2013 et janvier 2016, sept (13,7 %) ont recu une radiotherapie concomitamment et huit (15,7 %) avant l’ipilimumab. Le suivi median etait de 11,2 mois [1–64 mois]. Les cas de toxicite de grade 3 ou plus etaient principalement cutanes, digestifs (diarrhees), sans difference significative entre les deux groupes. La survie sans progression mediane etait de 5 mois [intervalle de confiance a 95 % : 2,0 ;7,9] dans le groupe irradie contre 9,2 mois [6,3–12 mois] dans le groupe non irradie (p = 0,168) et la survie globale mediane etait de 28,4 mois [22–34,8 mois] dans le groupe irradie contre 27,8 mois [23,6–32 mois] dans le groupe non irradie (p = 0,7). Conclusion Nous n’avons pas retrouve de difference significative de survie sans progression ni de survie globale entre les patients traites par ipilimumab et irradiation et les patients traites par ipilimumab seul. Neanmoins, l’association de radiotherapie et d’immunotherapie par ipilimumab a ete bien toleree. Le caractere retrospectif et le faible effectif de notre etude sont des limites de ce travail, qui necessiterait une evaluation prospective sur une plus large cohorte.

Introduction et but de l’etude L’efficacite de l’association de la radiotherapie et de l’immunotherapie reste controversee notamment en raison de l’absence d’evaluation de groupes homogenes de patients recevant une meme ligne de traitement. Notre etude retrospective a evalue cette association dans un groupe homogene de patients pris en charge par immunotherapie en deuxieme ligne pour un melanome metastatique avec mutation de B-RAF apres therapie ciblee. Materiel et methodes Les donnees cliniques et de radiotherapie ont ete recueillies chez tous les patients atteints de melanome metastatiques avec mutation de B-RAF pris en charge par immunotherapie en deuxieme ligne de traitement metastatique apres une therapie ciblee dans notre centre. Les patients ayant recu d’autres therapeutiques ou une immunotherapie en premiere ligne ont ete exclus de l’analyse. Les donnees de survie et de toxicite ont ete comparees entre les patients traites par irradiation durant l’immunotherapie et les patients non irradies. Resultats et analyse statistique Entre novembre 2011 et mars 2017, 114 patients remplissant les criteres d’inclusion ont ete pris en charge au CHU de Bordeaux. Trente-sept patients ont recu une irradiation durant l’ immunotherapie (soit 32,4 %). Dans notre population, 51 patients ont recu du pembrolizumab (soit 45 %), 24 du nivolumab (soit 21 %), 35 de l’ipilimumab (soit 31 %) et quatre de l’ipilimimab et du nivolumab (soit 3 %). Il n’existait pas de difference significative entre le groupe irradie et le groupe non irradie selon le type d’immunotherapie recue (p = 0,332). Apres un suivi median de 11,9 mois, la survie sans progression mediane apres le debut de l’immunotherapie etait de 9,4 mois pour le groupe irradie contre 10,8 mois pour le groupe non irradie (p = 0,809). La survie globale mediane etait de 15,6 mois pour le groupe irradie contre 20,1 mois pour le groupe non irradie (p = 0,871). Il n’existait pas de difference de toxicite de grade 2 ou plus entre les groupes (p = 0,332). Conclusion Dans notre etude, l’association de radiotherapie et d’immunotherapie a ete bien toleree, sans difference de survie entre les patients pris en charge par immunotherapie avec radiotherapie concomitante et ceux recevant l’immunotherapie seule.

Introduction et but de l’etude L’analyse radiomique par machine-learning des metastases cerebrales pour predire l’histologie de la tumeur primitive presente des perspectives prometteuses, mais reste peu exploree. Materiel et methodes Entre 2012 et 2018, 122 patients pris en charge au CHU de Bordeaux par radiotherapie pour des metastases cerebrales secondaires de cancer primitifs bronchiques non a petites cellules (54 %), renaux (11 %) ou de melanomes (35 %) ont ete inclus. A partir d’IRM en sequence T1 avec injection de produit de contraste, 161 metastases cerebrales ont ete segmentees manuellement. Apres la normalisation par differentes methodes de re-echantillonnage (taille des voxels, echelle de niveaux de gris), 38 indices de texture ont ete extraits puis une association a ete recherchee entre le modele radiomique et le type histologique. Enfin, deux algorithmes de machine-learning, reseau neuronal artificiel et foret aleatoire, ont ete compares pour tester leur capacite diagnostique a distinguer les cancers primitifs bronchiques non a petites cellules des melanomes. Resultats et analyse statistique Une heterogeneite des valeurs d’indices a ete observee selon les methodes de re-echantillonnage, et plusieurs traits radiomiques ont significativement ete associees a l’histologie en analyse unifactorielle. L’algorithme de foret aleatoire, tenant compte des 38 indices radiomiques, a ete plus predictif (receiver operating characteristic -area under curve [ROC-AUC] : 0,85, exactitude de prediction de 75 %) que le reseau neuronal artificiel (AUC : 0,66, exactitude 59 %). L’ajout du sexe et de l’âge des patients dans le modele a permis une amelioration de la performance (AUC respectives de 0,89 et 0,75, avec une exactitude de 75 % et 68 %). Conclusion L’analyse radiomique de metastases cerebrales sur l’IRM en sequence T1 apres injection de produit de contraste par l’algorithme de foret aleatoire semble prometteuse quant a la discrimination des types histologiques de cancers primitifs bronchiques non a petites cellules et de melanomes. Elle pourrait orienter la prise en charge de metastases cerebrales isolees ou en cas de cancers primitifs simultanes differents. Ces resultats preliminaires restent a confirmer par une etude multicentrique et sur d’autres types histologiques, et avec une methodologie plus robuste.
