Background And Purpose: To review the literature on techniques used in high-dose radiotherapy of lung cancer in order to develop recommendations for clinical practice and for use in research protocols.
Patients And Methods: A literature search was performed for articles and abstracts that were considered both clinically relevant and practical to use. The relevant information was arbitrarily categorized under the following headings: patient positioning, CT scanning, incorporating tumour mobility, definition of target volumes, radiotherapy planning, treatment delivery, and scoring of response and toxicity.
Results: Recommendations were made for each of the above steps from the published literature. Although most of the recommended techniques have yet to be evaluated in multicenter clinical trials, their use in high-dose radiotherapy to the thorax appears to be rational on the basis of current evidence.
Conclusions: Recommendations for the clinical implementation of high-dose conformal radiotherapy for lung tumours were identified in the literature. Procedures that are still considered to be investigational were also highlighted.

Patients who develop Ewing sarcoma with extra-pulmonary metastasis have a poor prognosis. A recent French protocol, CombinaiR3, was set up to evaluate the efficacy of induction chemotherapy followed by high-dose chemotherapy and metronomic maintenance treatment. It is now closed for inclusions and while waiting for the results, we propose a French consensus guideline for the management of patients diagnosed with Ewing sarcoma with extra-pulmonary dissemination.

While biological studies of the FLASH effect in proton beams have mainly been performed in the plateau region at maximum beam energy and current, this type of delivery has limited clinical applications. Naturally, it is anticipated that plans to treat patients clinically with FLASH-radiotherapy (FLASH-RT) will capitalize on the Bragg peak. However, as the proton spot widens with depth, the time required to deliver the entire dose to any single point increases.

Rationale: Stereotactic body radiotherapy (SBRT) is a precise treatment modality for lung cancer, delivering high-dose radiation to tumors while sparing surrounding organs. However, because of their intracardiac placement and proximity to the chest radiation field, leadless pacemakers (LLPMs) pose unique challenges that are not fully addressed by the existing protocols for conventional pacemakers.
Patient Concerns: In this case study, we aimed to emphasize the importance of identifying LLPMs before initiating SBRT for lung cancer and to discuss the necessary adjustments in treatment planning needed to accommodate these devices.

Background: Preclinical animal studies have demonstrated that radiation treatment (RT) can induce effects beyond the anatomical site of irradiation. Non-targeted effects of RT (NTER) have been sporadically reported in clinical settings. However, with the advent of high-dose stereotactic radiation techniques (SRT) and immunotherapy (IT), renewed attention has been given to NTER.

Background: Radiotherapy destroys tumor cells primarily through direct DNA damage by high-energy particles or indirect DNA damage by free radicals. High-dose radiotherapy (HDR) destroys tumor cells while also damaging normal cells and may potentially cause immunosuppression. The effect of low-dose radiotherapy (LDR) on the tumor microenvironment (TME) may differ from those of HDR.
