[Informed consent in radiotherapy care]. / Consentement aux soins en radiothérapie.

Obtaining consent to care requires the radiation oncologist to provide loyal information and to ensure that the patient understands it. Proof of such an approach rests with the practitioner. The French Society for Radiation Oncology (SFRO) does not recommend the signature of a consent form by the patient but recommends that the radiation oncologist be able to provide all the elements demonstrating the reality of a complete information circuit.

[Survey by SFRO, SNRO and AFPPE about the evolution of the radiation therapist profession in France]. / Enquête SFRO­SNRO­AFPPE sur l'évolution du métier de manipulateur exerçant en radiothérapie en France.

PURPOSE: As part of the multidisciplinary team, radiation therapists are in charge of elements of treatment preparation and delivery of radiotherapy to cancer patients. Helping scientific and technological improvements, more and more patients with cancer were treated with radiotherapy including hypofractionnated radiotherapy, that explain the increase of demands on services. The professional impacted by this increase of demands are radiation oncologists and medical physicists. The opportunity to push forward the radiation therapist's competencies appears with the possibility to shift them some tasks. In this context, a first work was performed with objectives to have an overview of the tasks shifted to radiation therapists in France, the tasks that they could perform but also to evaluate some criteria of job satisfaction. MATERIAL AND METHODS: The committee of "new status and value of status" including six radiation oncologists (the French society of radiation oncology [SFRO] et national union of radiation oncologists [SNRO]) and six radiation therapists committee members of the French association of radiation therapists (AFPPE), built a questionnaire including three parts: demographic characteristics, tasks shifted and job satisfaction criteria. In total, the questionnaire included 19 questions and 24 items assessed with a four point-Likert scale (ranging from "completely disagree" to "completely agree"). This survey, formatting with google form, was tested by the committee members and the final version was sent to the SFRO, AFPPE and SNRO members, before being disseminated on the social networks. RESULTS: From November 18th 2022 to December 31st 2022, 492 responses were received (response rate=18.3%): 55 % of the respondents had at least 11 years of experience in radiotherapy. The respondents worked in different type of health facilities (36 % in specialized cancer centres, 19.5 % in private centers, 17.5% in university and general hospital, 10.2% in general hospital). More than » of the respondents had a teaching lecturer activity, 20% had a management team activity and a research activity for 18%. Less than 10% of the respondents had another degree than that of radiation therapist: university degree (n=27), degree in dosimetry (n=11) and master (n=3). More than 76% would like to be trained and to have access to the advanced practice, more than 50% would like expend competencies with a university degree, 30% with a master and 67% would like to participate in research. Forty-two percent of the respondents were involved in a task shifting (excluding decree relating to acts and activities carried out by radiation therapists) and among the radiation therapists non-involved, 63% would be interested in being. Regarding job satisfaction, 53% of the respondents were satisfied with their job and their salary and 68% believed that their job occupation is in line with their professional aspirations. More than 2/3 of the respondents described a significant workload and mental load, 53% thought to have time for their patient care and 70% felt some organisational difficulties. CONCLUSION: This survey shows: (i) A significant involvement of radiation therapists in the task shifting; (ii) A very strong demand for career development, in particular with existing degrees or to be created degree such as advanced practice; and (iii) The need to reinforce a job satisfaction for almost the half of the respondents, linked to a workload, a mental load and some organisational difficulties.

[Radiation therapists shortage in France: Organizational consequences and difficulties in deploying new missions and/or tasks delegation]. / Métier de manipulateur en radiothérapie en tension en France : conséquences organisationnelles et difficultés à déployer de nouvelles missions et/ou délégation de tâches.

PURPOSE: Radiation therapists shortage has been evaluated at national level in France, specifically in oncology radiotherapy, in terms of: (i) organizational adaptations, (ii) impact on patients care, and (iii) difficulties in deploying new missions and/or tasks delegation. MATERIALS AND METHODS: French professional organisations representing radiation therapists - SFRO, SNRO and AFPPE - sent their members a national survey (ten questions on 32 items). RESULTS: From 18 November 2022 to 31 December 2022, 55 responses were received (response rate: 31%) from radiotherapy managers or department heads; 51% had a structure comprising three to five treatment rooms (receiving 500 to 1000 patients per year [36%], or 1500 to 2000 patients per year [33%]). Activities performed were intensity-modulated radiotherapy (100%), stereotaxic radiotherapy (85%), brachytherapy (40%), adaptive radiotherapy (34%). These structures described consequences in closing machine time for 25% of them (reduction of the hourly volume greater than 10% in 57%) with the following consequences in the last 6 months: (i) an extension of the period of medical care (78%), a closing of one or more accelerators (50%) and the development of moderate hypofractionation scheme or extreme hypofractionation (50%). In current functioning, linear accelerators can deliver treatments with a team of two radiation therapists per room for a short day (43%) or two to four radiation therapists per room teams for a long day (40%). During the last 6 months, there has been a 10% increase in linear accelerators operating with a single team. (ii) regarding treatment planning: 16.4% reported a decrease in the opening amplitude (less than 20% in 44% of cases, from 20 to 50% in 33 % of cases). The initial scheduling of appointments for radiotherapy sessions was carried out by radiation therapists in 84% of the departments in current functioning (0.1 to 1 FTE dedicated to this activity in 62% of the departments). Over the last 6 months, there has been a clear reduction in the number of dedicated FTEs: [FTE=0.1 to 1]=-8%; [FTE=0]=+7%. (ii) Regarding tasks delegation (excluding the decree on acts and activities carried out by the radiation therapist): organ at risk delineation is partially performed by radiation therapist in 26% of the centres; caregiver support time in 78% (56% totally or 22% partially). This activity has been reduced by 42%. Seventy-five percent of departments want to develop new techniques, patient-centered approaches (44%), implement task delegation (organ at risk delineation: 58%; weekly consultations: 67%; positioning imaging validation: 71%), and 78% of departments are interested in developing advanced radiotherapy practice. However, the number of radiation therapists is considered insufficient in their implementation in 76% of cases (one to two FTE missing for 72% of structures). CONCLUSION: This survey shows a significant impact of radiation therapist shortage in radiotherapy oncology care (treatment delays, access to caregiver support time, workload on treatment teams), and represents a major obstacle to the development of radiotherapy structures.

[French careers in oncology radiotherapy: Crossing views]. / Carrières en oncologie radiothérapie : réflexions croisées SFjRO-SFRO-SNRO.

The French Society of Young Radiation Oncologists (SFjRO), the National Union of Radiation Oncologists (SNRO) and the French Society of Oncological Radiotherapy (SFRO) aim to reconcile career opportunities and demographic needs in oncology. In 2021, 932 radiation oncologists (RO) are in regular activity in France, this represents an increase of more than 20% in ten years. Physician distribution is changing in public hospitals, cancer centers and private clinics. Currently one third of ROs works in each sector. In addition, fifteen percent of ROs have a mixed activity. In 2021, 180 young RO (trainees and residents) were questioned by SFjRO board about their training, internship, coaching and career guidance. An interactive communication was organized during the 32nd SFRO Meeting in 2021. It was an opportunity to bring the results of this study. More than 70% RO interviewed answered to the survey, for 55% among them, career choice was difficult. In order to help young ROs in their professional approach, three RO made an oral presentation during this session, about radiotherapy in public hospitals, private centers or with a mixed practice. The aim of this article is to summarize the highlights of the last SFjRO/SFRO session: expectations of young RO, career prospects and trends.

[Clinical research in radiotherapy oncology in private sector: A reality with a possible future?] / Recherche clinique en oncologie radiothérapie dans le secteur libéral : une réalité avec un avenir possible ?

Clinical research is one of the activities of medical practice, particularly in oncology including radiotherapy. It was developed in the public sector and then in the liberal sector, in compliance with regulatory institutions, resulting in a doubling of inclusions over the last decade. Setting up and developing clinical research in the liberal sector are major axes in terms of interests: improving the proposition of care, access to innovation, to keep patients, intellectual stimulation, encouraging recruitment, activity of scientific publications, financial valorisation, quality of visibility… An inventory on French national territory via the national union of iadiotherapists oncologists (SNRO) and the club of liberal oncologists (Colib) is reported in this article, as well as examples of structuring and organization.

Radiation therapy: Regulatory framework and constraints.

The purpose of this article is to describe the regulatory framework of the radiotherapy practice in France.

Guidelines for external radiotherapy and brachytherapy procedures: 3rd edition.

The purpose of the first two editions of the guidelines for external radiotherapy procedures, published in 2007 and 2016 respectively, was to issue recommendations aimed at optimising, harmonising and standardising practices. The purpose of this third edition, which includes brachytherapy, is identical while also taking into account recent technological improvements (intensity modulation radiation therapy, stereotactic radiotherapy, and three-dimension brachytherapy) along with findings from literature. Part one describes the daily use of general principles (quality, security, image-guided radiation therapy); part two describes each treatment step for the main types of cancer.

[Dose constraints to organs at risk for conformational and stereotactic radiotherapy: Small bowel and duodenum]. / Contraintes de doses aux organes à risque en radiothérapie conformationnelle et stéréotaxique : intestin grêle et duodénum.

Radiotherapy of abdominopelvic primary or secondary lesions in conformational or stereotactic techniques is in full development. The small bowel is highly sensitive to irradiation and is the main organ at risk limiting prescription doses. This literature review aims to define the dose constraints to the small bowel and the duodenum in conformational and stereotactic body radiotherapy. The small bowel including the duodenum, jejunum and ileum is delineated on the simulation scanner. The radio-induced intestinal toxicities are acute related to the cellular depopulation of the intestinal mucosa, and late of more complex pathophysiology associating depletion in stem cells, microangiopathy, chronic inflammation and fibrosis. The main predictive factor of intestinal toxicity is the dose-volume ratio. In conformational radiotherapy, the dose constraints to the duodenum are: V25Gy<45% and V35Gy<20%. The jejunum and ileum dose constraints are for delineation by intestinal loop or peritoneal cavity respectively: V15Gy<275mL or V15Gy<830mL and V45Gy<150mL. In stereotactic body radiotherapy, small bowel dose constraints depend on fractionation and are defined on a small volume and on a maximum dose at one point. Intestinal toxicity is also dependent on factors intrinsic to the patient and radiosensitizers such as targeted therapies or chemotherapies. With the development of new techniques allowing dose escalation on the tumour and the development of inverse planning, the definition of dose constraints to the small bowel is essential for current practice.

[((18)F)-fluorodeoxyglucose PET/CT in cervix cancer: lymph node assessment and prognostic/predictive value of primary tumour analysis]. / Tomographie par émission de positons au ((18)F)-fluorodésoxyglucose dans les cancers du col utérin : évaluation ganglionnaire et valeur pronostique/prédictive des données de la tumeur primitive.

PURPOSE: In cervix carcinoma: (a) to evaluate the ability of ((18)F)-fluorodeoxyglucose (FDG) positron emission tomography (PET) in the lymph node detection; (b) to investigate the prognostic and predictive value of the primary cervical PET parameters. PATIENTS AND METHODS: Ninety patients treated for cervix carcinoma and evaluated initially by MRI and FGD PET were included. The performances of FDG-PET for lymph node detection (relatively to the lymph node dissection) have been described (sensitivity, specificity, positive predictive value and negative predictive value). PET tumour parameters analyzed were: maximum standard uptake value (SUVmax), the volume and the maximum diameter. The prognostic and predictive values of these parameters were investigated. The tumour response was evaluated on surgical specimens. RESULTS: PET detected the cervical tumour with a sensitivity of 97% (mean values: SUVmax=15.8, volume=27 mm(3), maximum diameter=47). For the detection of the lymph nodes, the values of sensibility, specificity, positive predictive value and negative predictive value were: 86, 56, 69 and 78% in the pelvic, and 90, 67, 50 and 95% for the para-aortic area, respectively. The SUVmax was correlated with histologic response (P=0.04). The frequency of partial histological response was significantly higher for tumour SUVmax>10.9 (P=0.017). The maximum PET diameter and pathologic response had an impact on disease-free survival and overall survival in multivariate analysis (P<0.05). CONCLUSION: PET has high sensitivity in detecting pelvic and para-aortic lymph nodes. Some primary cervical tumour PET parameters are useful as prognostic and predictive factors.
