Importance of Margins, Radiotherapy, and Systemic Therapy in Mucosal Melanoma of the Head and Neck
Bibliographic record
Abstract
OBJECTIVES/HYPOTHESIS: The ideal strategy in the treatment of mucosal melanoma of the head and neck (MMHN) remains unclear. Our objective was to evaluate the importance of surgical margins, radiotherapy, and systemic therapy in MMHN. STUDY DESIGN: Retrospective Single Institutional Review. METHODS: Retrospective review of patients with MMHN treated at a tertiary care oncology center between 1999 and 2016. RESULTS: Seventy-six patients were included, 60 of whom were treated with curative intent. Negative or close margins compared with positive margins were associated with higher 3-year overall survival (OS) (62% vs. 29% vs. 13% P = .012), disease-free survival (33% vs. 29% vs. 4% P = .003), and distant control (48% vs. 29% vs. 22% P = .039). Cases with pre-/postoperative radiotherapy had a marginally higher locoregional control versus without (69% vs. 59%, P = .117). Immunotherapy for recurrent and/or metastatic disease was associated with an increase in 3-year OS (15% vs. 3% P = .01). CONCLUSION: Achieving negative surgical margins is relevant in disease control. Despite small sample size, our data suggest that radiotherapy may enhance surgical outcomes. Immunotherapy has therapeutic benefit. LEVEL OF EVIDENCE: 3 Laryngoscope, 131:2269-2276, 2021.

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.
