Stereotactic body radiotherapy, also referred to as extreme hypofractionation, uses advanced delivery techniques to administer high radiation doses per fraction. Since its introduction in the early 2000s, several single-centre and two multi-institutional randomized trials have evaluated stereotactic body radiotherapy for prostate cancer, typically reporting median follow-ups of 5 to 10 years. Given favourable outcomes, stereotactic body radiotherapy has now become a standard of care for intermediate prostate cancer. The aim of this review is to report the current evidence so far, and to assess specificities of this irradiation modality. Extreme fractionation in case of pelvic irradiation or intraprostatic relapse will not be addressed in this review.

We present the recommendations of the Société française de radiothérapie oncologie (SFRO; the French society for radiation oncology) regarding the indications and techniques for external beam radiotherapy for bladder cancer. Together with radical cystectomy, trimodal therapy for well-selected patients is one of the standard-of-care treatments in the management of localized muscle invasive bladder cancer, defined as a maximal trans-urethral resection of the bladder tumour, followed by radiotherapy and concomitant chemotherapy. Adjuvant radiotherapy is an option for patients with pathological high-risk bladder cancer. In the metastatic setting, consolidative radiotherapy is still under evaluation. Palliative radiotherapy using a hypofractionated regimen is a valid option in symptomatic patients.

Complementary therapies are used by cancer patients at every stage of treatment. Denying this reality would mean denying our patients’ quest for well-being and autonomy. It would also mean ignoring the satisfaction they derive from them. There is a need for clarification on the definitions of the terms used, as well as on regulations and practitioner training. Developing clinical studies of good methodological quality that are adapted to practice is essential to providing scientific proof of efficacy and safety (qualitative and quantitative evaluations). Integrating complementary therapies with supportive care is a fundamental interdisciplinary approach to integrative oncology. This integration must be considered at all levels – institutionally, within the framework of the service project, and in the patient's care pathway – in order to optimize quality of care and overall management.

This review aims to explore the radiobiological rationale and clinical evidence supporting the use of hypofractionated radiotherapy in the management of rectal tumours, particularly in neoadjuvant treatment strategies and organ preservation approaches. An overview of key randomized controlled trials on hypofractionated radiotherapy, also called short-course radiotherapy, was conducted. Clinical trials have demonstrated oncological equivalence between hypofractionated radiotherapy and standard long-course chemoradiotherapy in terms of overall survival and local recurrence, but short-course radiotherapy represents a relevant therapeutic option for frail or elderly patients. In the total neoadjuvant treatment context, short-course radiotherapy combined with consolidation chemotherapy improves distant control but may increase the risk of local recurrence. Recent studies suggest that short-course radiotherapy can lead to organ preservation when followed by transanal surgery or active surveillance in well-selected patients, and that its combination with immune checkpoint inhibitors can safely increase complete response rates. Its use in total neoadjuvant treatment, immunotherapy combinations, and organ preservation strategies requires careful patient selection and further comparative trials to refine its indications.

T1N0 non-small cell lung cancers account for about 20 % of all lung cancer cases and are defined as tumours up to 3 cm without nodal or distant metastasis. The incidence of early-stage diagnoses is increasing, largely driven by the implementation of low dose computed tomography screening programs. Surgery has long been considered the standard of care for these tumours, offering excellent oncologic outcomes and allowing essential pathological staging. However, surgery may be indicated or poorly tolerated in certain populations, particularly elderly or medically inoperable patients. Stereotactic body radiotherapy has emerged as a non-invasive alternative with high local control rates and reduced early morbidity. This raises a critical question: should all patients with early-stage non-small cell lung cancer be managed surgically, or is there a role for treatment individualization? Current evidence highlights the need of balancing curative intent with treatment-related risks. Several clinical trials are currently evaluating stereotactic body radiotherapy in operable patients, aiming to identify subsets that may derive benefit from a non-surgical approach. This review advocates for a personalized, patient-centred treatment strategy, integrating tumour characteristics, operability, comorbidities, and patient preference.

Purpose
Radiation-induced lung injury is relatively uncommon but disabling, and a dose-limiting factor in thoracic radiotherapy. This complication is mainly encountered following radiotherapy for lung cancers. We provide recommendations for good clinical practice, defining the prevention and management of radiation-induced lung injury.
Methods
Members of the Association francophone pour les soins oncologiques de support (Afsos; French-speaking association for oncology care and support) and the Société française de radiothérapie oncologique (SFRO, French society for radiation oncology) set up a multidisciplinary working and review group to draft these recommendations for 2023 to 2024, based on a systematic review of the literature.
Results
Radiation-induced lung injury comprises several forms, mainly resulting from acute toxicity (radiation pneumonitis) and chronic toxicity (radiation fibrosis). Specific forms can be identified, such as organising pneumonia (formerly bronchiolitis obliterans organizing pneumonia) and radiation recall pneumonia. The risk factors are numerous and include dosimetric risk factors, patient-related factors and tumour-related factors. New challenges include the specific complications of stereotactic radiotherapy, the combination of recent specific oncological treatments including tyrosine kinase inhibitors and immunotherapy, and the association with certain pathologies such as interstitial lung disease.
Conclusion
The profile of radiation-induced lung injury is evolving with new radiotherapy techniques and innovative systemic oncology treatments. Rapid detection and management of these side-effects are essential for good patient care.

Research is emerging within the French radiation therapists’ community. In this context, the present article aimed to provide an overview of the research process from an idea to a research project, highlight several funded French research projects led by radiation therapists, and identify the barriers and facilitators to these professionals conducting research. The research process follows those of the traditional scientific method, beginning with an idea inspired by clinical practice. This idea is then refined through a review of the literature which helps to challenge preconceived ideas and outdated practices. A clear research question is formulated using established models and is subsequently refined to ensure the project is feasible, interesting, novel, ethical and relevant. The process should be done in an interprofessional environment. To date, several projects have been funded by national or regional grants reflecting growing interest and engagement in research among radiation therapists in France. This progress has been made possible thanks to institutional support and dedicated research grants available to radiation therapists. Nonetheless, several challenges remain, including the need for training in scientific method and evidence-based practice, proficiency in English, and access to literature.

Some radiotherapy courses are cancelled or stopped permanently, mostly in palliative situations, due to rapid decline in patient condition, complications, death, or inability to complete the sessions. These occurrences negatively affect patients (increased morbidity and mortality, useless constraints), healthcare professionals (ethical distress), and departmental operations (longer treatment start delays, under-utilization of resources). By reducing the number of non-beneficial (“non-pertinent”) irradiations, we have developed an eight-point action plan to implement in radiation department: (1) provide stronger training in palliative radiotherapy (in both initial and continuing medical education, including communication skills and learning to say “no” when appropriate); (2) perform a more rigorous assessment of patients at the initial consultation (evaluating general condition, nutritional status, supportive care needs, and prognosis); (3) create a dedicated forum for team discussions and reinforce the role of the radiotherapy technical meeting when difficulties arise during simulation or treatment planning; (4) better tailor radiotherapy technique (e.g., use of intensity modulation) as well as total dose, fractionation, to each patient's profile – especially for those most at risk or frail; (5) improve management of care timelines and define key objectives to minimize delays, adapting resources and organization to needs (e.g., a “zero delay” project group with specific indicators); (6) establish a process for medical and multidisciplinary reevaluation during the course of treatment that can lead to stopping or modifying the radiotherapy if the indication becomes questionable; (7) integrate palliative radiotherapy into the overall personalized supportive care plan, with early palliative care involvement from the time of incurable disease diagnosis; (8) evaluate professional practices (through defined indicators, satisfaction surveys, and morbidity-mortality meetings) to drive continuous improvement.

However, advances in tumour biology and the emergence of molecular signatures have identified subgroups with a very low risk of recurrence, particularly patients with luminal A cancers, reigniting the debate on potential radiotherapy de-escalation in this population. In addition, achieving a complete pathological response in patients who have received neoadjuvant chemotherapy suggests the possibility of adapting radiotherapy indications. This article aimed to present the major currently available data on the omission of radiotherapy in the treatment of luminal A phenotype breast cancers after conservative surgery, as well as ongoing trials on irradiation de-escalation in cases of complete pathological response after neoadjuvant chemotherapy, particularly for the cN1–ypN0 and cN2–3–ypN0 subtypes. Several prospective studies and randomized trials, including LUMINA, PRIME II, and trials using genomic signatures (POLAR, Oncotype DX®, Prosigna®), suggest the feasibility of omitting radiotherapy for some very low-risk patients, without demonstrated effects on overall survival. However, the persistent benefit of local control has been observed. The National Surgical Adjuvant Breast and Bowel Project (NSABP)-B51/Radiation Therapy Oncology Group (RTOG) 1304 trial and Radiotherapy After Primary Chemotherapy (RAPCHEM) registry showed that the omission of nodal radiotherapy could be considered after a complete nodal pathological response (ypN0), with good short-term locoregional control, although definitive long-term results have not been reported. The omission of radiotherapy for breast cancers with a good prognosis, particularly in patients with luminal A tumours and those with a complete response after neoadjuvant treatment, represents a promising avenue for therapeutic de-escalation. However, it must be determined based on strict biological and clinical selection criteria and validated via long-term controlled trials.
保守性手术后辅助放疗是浸润性乳腺癌的标准治疗方法，可降低局部复发风险和远期死亡率。然而，肿瘤生物学的进步和分子特征的出现已经确定了复发风险非常低的亚群，特别是腔a癌患者，这重新引发了对这一人群中潜在的放疗降级的争论。此外，在接受新辅助化疗的患者中获得完全的病理反应表明适应放疗指征的可能性。本文旨在介绍目前可获得的主要数据，包括保守手术后腔内A型乳腺癌省略放疗的治疗，以及正在进行的新辅助化疗后完全病理反应的照射降级试验，特别是cN1-ypN0和cN2-3-ypN0亚型。一些前瞻性研究和随机试验，包括LUMINA， PRIME II和使用基因组特征（POLAR, Oncotype DX®，Prosigna®）的试验，表明对一些极低风险患者省略放疗的可行性，而对总生存期没有证明的影响。然而，局部控制的持续效益已经被观察到。国家外科辅助乳腺和肠项目(NSABP)-B51/放射治疗肿瘤组（RTOG） 1304试验和原发性化疗后放疗（RAPCHEM）注册显示，在完全淋巴结病理反应（ypN0）后，可以考虑省略淋巴结放疗，具有良好的短期局部区域控制，尽管明确的长期结果尚未报道。预后良好的乳腺癌患者，特别是腔内a肿瘤患者和新辅助治疗后完全缓解的患者，不进行放疗，代表了治疗降级的有希望的途径。然而，它必须根据严格的生物学和临床选择标准来确定，并通过长期对照试验进行验证。
