Identifying markers of cachexia and nutritional deficit on radical radiotherapy outcomes in lung and head and neck cancer.
Review in Current opinion in supportive and palliative care, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purpose of reviewCancer cachexia is a multifactorial syndrome characterised by weight loss, muscle wasting, malnutrition, and systemic inflammation. Although well-recognised in advanced cancer, its significance in patients receiving radical radiotherapy for potentially curable malignancies is less well understood. This review examines the impact of cachexia-related biomarkers in patients undergoing radical radiotherapy for lung or head and neck cancers. RECENT
findingsMany studies evaluating cachexia-related phenotypes do not explicitly use the term 'cachexia'. Therefore, this review focuses on four key domains of cachexia: weight loss, malnutrition, sarcopenia, and systemic inflammation. Across both tumour types, these biomarkers were frequently associated with poorer survival, increased treatment toxicity, and reduced treatment tolerance in patients receiving radical radiotherapy with curative intent for lung or head and neck cancers. However, the literature is dominated by retrospective studies employing heterogeneous definitions in poorly defined patient groups. SUMMARY: Cachexia-related biomarkers provide important prognostic information in patients receiving radical radiotherapy for lung cancer and head and neck cancer. Routine assessment of weight loss, nutritional status, body composition, and systemic inflammation may improve risk stratification and support personalised treatment decisions. Future prospective studies should incorporate standardised cachexia assessments to validate their clinical utility and evaluate emerging nutritional, prehabilitation, and anti-cachexia interventions.
