Clinical Versus Pathologic Laryngeal Cancer Staging and the Impact of Stage Change on Outcomes

Objectives/Hypothesis Evaluate the impact and accuracy of clinical laryngeal cancer staging. Study Design Retrospective cohort study. Methods Two hundred sixty‐five consecutive patients with laryngeal squamous cell carcinoma who underwent total laryngectomy from 2001 to 2017 were studied. Clinical versus pathologic tumor (T) and nodal (N) categories were compared. Logistic regression and Cox proportional hazards analyzed the association of stage change with perioperative factors and outcomes. Results Forty‐seven patients (17.7%, accuracy = 0.969 ± 0.010 [standard error]) changed between T1‐2 and T3‐4. Sixty‐four patients (24.1%, accuracy = 0.866 ± 0.020) had inaccurate N category. Salvage patients were less likely to have stage change (downstage: odds ratio [OR] = 0.20, 95% confidence interval [CI]: 0.08‐0.50, P
