Abstract
BACKGROUND: Mohs micrographic surgery (MMS) is an accepted treatment for nonmelanoma skin cancer and has an evolving role in melanoma. OBJECTIVE: To review oncologic outcomes of MMS and wide local excision (WLE) treatments for facial melanoma. METHODS AND MATERIALS: A retrospective review of patients with invasive melanoma of the face between 1997 and 2007 identified from the Alberta Cancer Registry (Canada) was performed. Outcome measures were local recurrence (recurrence <2 cm from excision scar), distant recurrence (regional or systemic), and disease-specific survival. RESULTS: One hundred fifty-one patients were available for analysis (60 MMS, 91 WLE). Median follow-up time was 48 months. The groups differed in tumor location and mitotic rate. Overall, there was no significant difference in 5-year local recurrence (7.9% WLE vs 6.2% MMS, p = .58), regional or systemic recurrence (18.8% vs 8.8%, p = 0.37) or disease-specific survival (82.8% vs 92.4%, p = .59). Breslow thickness was the only consistent predictor of local recurrence or other recurrence and disease-specific survival on multivariate analysis. Subset analysis of tumors with Breslow thickness less than 2 mm did not reveal any difference in outcomes. CONCLUSION: Mohs micrographic surgery has oncologic outcomes of local recurrence, distant recurrence and overall survival similar to those of WLE for invasive facial melanoma.

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 it
