Squamous cell carcinoma of the buccal mucosa: Outcomes of Treatment in the modern era
Bibliographic record
Abstract
OBJECTIVES/HYPOTHESIS: The objective of this study was to analyze the patterns of failure and to determine clinical and pathologic factors predictive of recurrence and survival of patients treated for squamous cell carcinoma of the buccal mucosa at Princess Margaret Hospital. STUDY DESIGN: Retrospective chart review. METHODS: A retrospective chart review of patients treated for buccal carcinoma between 1994 and 2004 was performed. Seventy patients with newly diagnosed and previously untreated squamous cell carcinoma of the buccal mucosa were included. Demographic, clinical, and pathological parameters were identified and correlated with outcomes. RESULTS: The patient cohort consisted of 33 males and 37 females. Most patients presented with early-stage local disease (T1-T2). Surgery was the primary treatment in 61 patients. Twenty-three patients were treated with postoperative radiotherapy. Median follow-up was 3.3 years. The 5-year local, regional, and overall control rates were 57.5%, 83.5%, and 50%, respectively. The 5-year overall survival rate was 69%. The 5-year disease-specific and recurrence-free survival rates were 76.4% and 46%, respectively. The only significant predictors of survival were the nodal status and extranodal extension. CONCLUSIONS: Carcinoma of the buccal mucosa is an aggressive disease, characterized by a high rate of locoregional failure. Transoral wide excision is an adequate treatment for early-stage lesions; however, a combined approach and an elective neck dissection should be considered in advanced lesions.

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.
