Survival After Orbital Exenteration for Primary Cutaneous Squamous Cell Carcinoma: A Retrospective Cohort Study
Bibliographic record
Abstract
BACKGROUND: Locally advanced periorbital cutaneous squamous cell carcinoma (cSCC) may require orbital exenteration, which is highly morbid. As immunotherapy develops, orbit preservation may become widespread, and data benchmarking survival with current standard-of-care surgery and radiotherapy are essential to the integration of this emerging method into modern treatment paradigms. This study aimed to determine the survival of patients after orbital exenteration for cSCC and investigate contributing factors. It was hypothesized that postoperative radiotherapy would be associated with improved survival. METHODS: This was a retrospective cohort study of patients with T3 and T4 cSCC undergoing orbital exenteration. Survival analysis was performed using Cox proportional hazards. RESULTS: The study enrolled 40 patients with a median age of 61.5 years who met the criteria. None of the patients had received preoperative radiotherapy. Age (hazard ratio [HR], 1.09; p = 0.019) and residual disease (HR, 9.00; p = 0.003) were associated with worse survival. Postoperative radiotherapy (HR, 0.003; p < 0.001) was associated with improved survival. Perineural, lymphovascular, and bony invasion and T and N stage were not associated with survival. Survival with postoperative radiotherapy was 94 % at 1 year, 87 % at 2 years, and 84 % at 5 years. CONCLUSIONS: The oncologic outcomes of orbital exenteration with postoperative radiotherapy for locally advanced head and neck cSCC are good. However, amelioration of the morbidity caused by resection of the eye would be ideal. Data to support immunotherapy as a sole therapy are currently limited, but a combination of neoadjuvant immunotherapy and surgical treatment may facilitate orbit-preserving treatment in the future.

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.
