Palliative Radiation Therapy: The Role of Radiation Therapy in Palliative and End-of-Life Care
Bibliographic record
Abstract
BACKGROUND: Radiation therapy (RT) remains one of the main pillars of cancer treatment, alongside systemic therapy and surgery. More than half of people with cancer will receive RT at some point during their treatment trajectory. Although RT contributes to cure in a substantial number of patients, more than half of patients treated with RT are treated with palliative intent. RT plays an integral role in alleviating symptoms, preserving function, and improving quality of life for patients with cancer. OBJECTIVES: The aim of this article is to provide information on the role of RT in palliative and end-of-life care. METHODS: A review of the literature and professional guidelines on palliative RT was performed. FINDINGS: This article provides foundational information for nurses on indications for palliative RT, possible side effects and toxicities associated with palliative RT, and challenges and barriers that may be encountered when considering palliative RT. Nursing implications, including the importance of a palliative approach to care, are discussed.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
