Association between nutritional risk index and outcomes for head and neck cancer patients receiving concurrent chemo‐radiotherapy
Bibliographic record
Abstract
BACKGROUND: Patients receiving chemoradiotherapy for head and neck cancer (HNC) are often malnourished. We assessed the utility of nutritional risk index (NRI) in HNC patients undergoing chemoradiotherapy. METHODS: A population-based retrospective review of HNC patients treated with curative chemoradiation was performed. Demographics, anthropometrics, overall survival (OS), and the composite treatment complication rate (G-tube dependence, radiation incompletion, 90-day mortality, and unplanned hospitalization) were collected. RESULTS: Two hundred ninety-two patients were identified. Average pretreatment and posttreatment NRI were 110 (SD 3) and 99 (SD 12), respectively (P < .01). Pretreatment NRI risk category, age, ECOG status, and tumor subsites were associated with OS on multivariate analysis. Pretreatment NRI risk category was associated with risk of treatment related complications. CONCLUSIONS: There was a significant decrease between pretreatment and posttreatment NRI in HNC patients receiving chemoradiation. Pretreatment NRI risk category may predict OS and composite treatment complications. Investigation of NRI as a prognostic factor is warranted.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
