Background: Palliative radiotherapy (RT) is commonly used for malignancy-associated hemoptysis. This study aims to determine RT control probability, durability, and influencing factors.
Methods: This single-institution prospective observational study included patients ≥18 years old with any lung malignancy and active hemoptysis.
Purpose: This guideline provides evidence-based recommendations for palliative external beam radiation therapy (RT) in symptomatic bone metastases.
Methods: The ASTRO convened a task force to address 5 key questions regarding palliative RT in symptomatic bone metastases. Based on a systematic review by the Agency for Health Research and Quality, recommendations using predefined consensus-building methodology were established; evidence quality and recommendation strength were also assessed.
(1) Background: Prognostication in patients with cancer receiving palliative radiotherapy remains a challenge. To improve the process, we aim to identify prognostic factors in this population from the literature and offer evidence-based recommendations on prognostication in patients undergoing palliative radiotherapy for non-curable or advanced cancers. (2) Methods: A systematic review was performed on the medical literature from 2005 to 2023 to extract papers on the prognosis of palliative radiotherapy patients with advanced cancer.

In this subset of patients, with very poor survival, various palliative RT dose fractionation schemes are used; but, in the absence of a guideline, practice patterns vary, and dose choice is mainly based on the physician's intuition. We divided the patients into three groups, according to the dose fractionation schedules received: low (A), intermediate (B), and high (C) dose groups, to study the potential differences in outcome between the different dose prescriptions.

Esophagogastroduodenoscopy revealed a friable non-obstructing esophageal tumor that appeared thickened on computed tomography (CT). Biopsies confirmed a poorly differentiated carcinoma.

Methods: Data were obtained from the Surveillance, Epidemiology, and End Results (SEER) database. Selected patients from 2009 to 2018 had locally advanced HNC, underwent upfront surgery, and were eligible for adjuvant RT.
Purpose Of Review: The authors aimed to highlight trends in, and evidence underlying the use of highly conformal radiotherapy (RT) techniques in conventional nonstereotactic palliative RT. The authors reviewed palliative-intent and curative-intent studies relevant to the use of intensity-modulated radiation therapy (IMRT) for the delivery of nonstereotactic conventional regimens to the brain, head and neck, thorax, abdomen and pelvis, and bone metastases.
Recent Findings: The use of IMRT has become standard with certain indications for brain metastases such as hippocampus-avoiding/limiting whole brain RT.
Purpose: The European Organisation for Research and Treatment of Cancer (EORTC) health-related quality of life questionnaire for anal cancer (QLQ-ANL27) supplements the EORTC cancer generic measure (QLQ-C30) to measure concerns specific to people with anal cancer treated with chemoradiotherapy. This study tested the psychometric properties and acceptability of the QLQ-ANL27.
Methods And Materials: People with anal cancer were recruited from 15 countries to complete the QLQ-C30 and QLQ-ANL27 and provide feedback on the QLQ-ANL27.
Background: An analytical tool is empirically validated and used to assess the delivered dose to liver lesions accounting for different types of errors in robotic radiosurgery treatment.
Material And Methods: A tool is proposed to estimate the target doses taking into account the translation, rotation, and deformation of a target. Translational errors are modeled as a spatial convolution of the planned dose with a probability distribution function derived from treatment data.
Purpose: To establish a practical contouring strategy with reference atlases for the abdominopelvic bowel bag on treatment planning computed tomography (TPCT) and cone beam computed tomography (CBCT) images.
Methods And Materials: A scoping literature review was done to evaluate the existing definitions and contouring guidelines for bowel bag and small bowel planning-at-risk volume-like structures. A comprehensive definition was proposed for the abdominopelvic bowel bag that expanded the Radiation Therapy Oncology Group Pelvic Normal Tissue Consensus definition.
Purpose: Brachytherapy is most often applied in the curative or salvage setting, but many forms of brachytherapy can be helpful for symptom palliation. Declining utilization is seen, for multiple reasons, such as lack of awareness, insufficient expertise, or poor access to equipment. High level evidence for many types of palliative brachytherapy has been lacking.

Despite the relatively good outcomes conferred by state-of-the-art chemoradiotherapy, further improving disease control and reducing toxicity has proven challenging. Developing and validating prognostic models using routinely collected data may provide new insights for treatment development and selection.

However, radiotherapy utilization (RTU) rates fall short of desired benchmarks in certain Canadian provinces. We aimed to describe provincial variations in RTU across Canada.

Objective: This study aimed to investigate the impact of chronic kidney disease on outcomes in patients with locally advanced rectal cancer.
Background: A mainstay therapy for pain relief from uncomplicated bone metastases is external beam radiation therapy. Single fraction radiation therapy (SFRT) is more convenient and cost-effective, causes fewer acute side effects, and is equivalent to multiple fraction radiation therapy for pain relief. Despite these advantages, radiation oncologists seldom prescribe SFRT.

Introduction: Nausea is a difficult symptom to report and measure in clinical trials. We conducted a pilot interview study to improve our understanding of the nausea experience.
Materials And Methods: Female patients with breast cancer that had experienced nausea during radiation therapy and/or chemotherapy underwent semi-structured interviews that focused on patient-defined and standard definitions, preferences for nausea grading scales, and nausea sub-features: intensity, location, timing/duration, character, associated symptoms, precipitating/alleviating factors, impact on quality of life.
