Outcomes associated with local treatment of nasal planum squamous cell carcinoma in dogs: 89 cases (2003–2020)
Bibliographic record
Abstract
OBJECTIVE: To describe the clinical characteristics, treatments, complications, and outcomes in dogs with nasal planum squamous cell carcinoma (SCC) undergoing local treatment. METHODS: A retrospective, multi-institutional study was performed. Medical records were searched to identify dogs diagnosed with nasal planum SCC. Variables were recorded from medical records and statistically analyzed. RESULTS: 89 dogs were included. The most common presenting complaint was a visible mass on the nasal planum (89%). Metastasis was detected in 12% of dogs at the time of local therapy. Local therapy consisted of surgical excision alone in 63 of 89 dogs (71%) and radiation therapy alone in 20 of 89 dogs (22%); 6 dogs had multiple local therapies. Tumor size decreased in 12 dogs (60%) undergoing radiation therapy alone. Local recurrence was reported in 19 of 89 dogs (21%), including 16 of 63 dogs (25%) treated with surgery alone. Median survival time of all dogs was 452 days (95% CI, 285 to 576). Median survival time among 33 dogs with documented disease progression was 336 days (95% CI, 189 to 458), versus 685 days (95% CI, 334 to 1,042) in 56 dogs that did not have documented disease progression, which was significantly different (P = .038). Documented disease progression was significantly associated with hazard of death (hazard ratio, 1.93; 95% CI, 1.03 to 3.63; P = .041). CONCLUSIONS: Dogs undergoing local treatment of nasal planum SCC had a favorable prognosis. Metastasis at the time of treatment was uncommon. Long-term survival was possible, particularly in cases without disease progression. CLINICAL RELEVANCE: Aggressive local therapy, particularly surgical resection, should be considered in dogs with nasal planum SCC.

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.
