Toxicity and outcomes in combined modality treatment of head and neck squamous cell carcinoma: cisplatin versus cetuximab
Bibliographic record
Abstract
AIMS: The standard of care for locally advanced head and neck squamous cell carcinoma (HNSCC) is radiation therapy (RT) with concurrent cisplatin (CIS). Patients with renal or cardiac dysfunction, hearing loss or poor performance status (PS) may receive RT and cetuximab (CET) at our institution. This study compares treatment toxicities and outcomes. METHODS AND MATERIALS: All patients treated with curative intent RT and concurrent CIS (100 mg/m 2 Day 1, 22, 43) or CET (400 mg/m 2 Day -7, 250 mg/m 2 weekly during RT) between August 2007 and July 2010 were reviewed and toxicity and outcomes analyzed. RESULTS: Among 349 subjects (262 RT-CIS, 87 RT-CET) characteristics were similar except in age, head and neck subsite and RT fractionation. RT-CIS required more dose reductions, delays, and unplanned admissions and received less intended systemic therapy (ST). Weight loss and gastrostomy-tube use were similar. RT-CIS caused more nausea/vomiting, while RT-CET was associated with more dermatitis and acneiform rash. With mean follow-up of 20 months and 16 months, RT-CIS subjects experienced improved 1-year locoregional control (LRC) (90% vs. 72%, P < 0.01), disease-free survival (DFS) (83% vs. 67%, P < 0.01) and overall survival (OS) (90% vs. 80%, P = 0.04). On multivariate analysis type of ST was associated with LRC and DFS, but not OS. CONCLUSIONS: In patients with locally advanced HNSCC, CIS and CET were associated with different toxicity profiles. RT-CIS was associated with improved LRC and DFS, but similar OS compared to RT-CET.

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.
