[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.

[Treatment of primary disease with irradiation in case of de novo metastatic breast cancer]. / Irradiation de la tumeur primitive en cas de cancer du sein métastatique synchrone.

Synchronous metastatic breast cancer accounts for 5 to 6% of all breast cancers in Western countries, which corresponds to nearly 2500 new cases per year in France. Irradiation of the primary tumour in cases of metastatic disease at diagnosis was historically reserved for palliative indications. However, progress in systemic treatments, a better understanding of the biological basis of metastatic dissemination, the genesis of the concept of oligometastatic disease and ablative treatments directed towards metastases are revolutionizing the management of patients with de novo stage IV breast cancer. Survival of these patients has improved markedly over the years, and several studies have investigated the carcinological benefit of local treatment of the breast tumour in patients with advanced diseases at diagnosis. This article provides an update on the role of irradiation of the primary tumour in breast cancer with synchronous metastases, and discusses its interest through published or ongoing trials.

[Interest of image-guided radiotherapy for brain tumors and positioning control]. / Apport du guidage par l'image pour le repositionnement au cours de la radiothérapie des tumeurs encéphaliques.

A narrow therapeutic index and more and more patients with long survival characterize primary and second brain tumors. Image-guided radiotherapy can increase accuracy of the patient's position during a course of intracranial irradiation thanks to a direct or indirect visualization of targets volumes. Treatment reproducibility and organ at risk-sparing are the primary issues, particularly with the development of stereotactic radiotherapy and protontherapy. Regarding intracranial treatments, image-guided radiotherapy seems to be a repetitive task based on skeletal structures registration. And yet, this innovation makes possible to assess the dosimetric impact of daily positioning variations avoiding invasive immobilizations. Image-guided radiotherapy offers automated tools to limit time consumption and furthers adaptive radiotherapy opportunities. Nevertheless, medical evaluation is still necessary and image processing should be strictly defined (frequency, use, performance). The purpose of this article is to describe image-guidance in brain irradiation, as repositioning tool and to focus on its recent prospects.

[Radiotherapy of hypopharynx cancers]. / Radiothérapie des cancers de l'hypopharynx.

The intensity-modulated radiotherapy is the gold standard in the treatment of hypopharynx cancers. Early T1 and T2 tumours could be treated by exclusive radiotherapy or surgery. For tumours requiring total pharyngolaryngectomy (T2 or T3), induction chemotherapy followed by exclusive radiotherapy or concurrent chemoradiotherapy are possible. For T4 tumours, surgery must be proposed. The treatment of lymph nodes is based on the initial treatment of the primary tumour. In non-surgical procedure, in case of sequential radiotherapy, curative dose is 70Gy and prophylactic dose is 50Gy. An integrated simultaneous boost radiotherapy is allowed (70Gy in 2Gy per fraction and 56Gy in 1.8Gy per fraction or 70Gy in 2.12Gy per fraction). Postoperatively, radiotherapy is used for locally advanced cancers with dose levels based on pathologic criteria (66Gy for R1 resection, 50 to 54Gy for complete resection). Volume delineation is based on guidelines.

[Radiotherapy of larynx cancers]. / Radiothérapie des cancers du larynx.

Intensity-modulated radiotherapy is the gold standard in the treatment of larynx cancers (except T1 glottic tumour). Early T1 and T2 tumours may be treated by exclusive radiation or surgery. For tumours requiring total laryngectomy (T2 or T3), induction chemotherapy followed by exclusive radiotherapy or concurrent chemoradiotherapy is possible. For T4 tumour, surgery must be proposed. The treatment of lymph nodes is based on the initial treatment of the primary tumour. In non-surgical procedure, in case of sequential radiotherapy, the curative dose is 70Gy and the prophylactic dose is 50Gy. An integrated simultaneous boost radiotherapy is allowed (70Gy in 2Gy per fraction and 56Gy in 1.8Gy per fraction or 70Gy in 2.12Gy per fraction).
