- Abstract
Background: We evaluated the prognostic value of lymph node ratio (LNR) in patients with advanced laryngeal and hypopharyngeal squamous cell carcinoma. Study Design: Retrospective chart review. Methods: Between 1994 and 2018, 79 patients underwent total laryngopharyngectomy and adjuvant therapy. LNR was determined and statistically compared to patients' overall survival (OS), disease‐specific survival (DSS), disease‐free survival (DFS), locoregional and distant failure. Results: The 5‐year OS, DSS and DFS rates were 45.6%, 73.4% and 56.9%, respectively. 24.1% and 25.3% developed loco‐ regional failure or distant metastatic disease, respectively. Univariate analyses showed that high LNR (cut‐off >0.07) was significantly associated with distant and locoregional failure. On multivariate analysis, LNR remained an independent predictor for OS (P =.004), DSS (P =.009) and DFS (P =.044). Conclusion: Increased LNR in patients with advanced laryngeal or hypopharyngeal carcinoma is significantly linked to shortened OS, DSS, DFS and higher locoregional and distant metastatic disease.
