Lymph node ratio: prognostic value in laryngeal cancer after primary total laryngectomy
Abstract Objectives: To evaluate Lymph node ratio (LNR) as a predictor for survival and recurrence of laryngeal cancer with metastatic lymph nodes (pN+). Study design: This retrospective study included patients who underwent primary laryngectomy combined with bilateral neck dissection, between October/2010 and April/2023. Results: A total of 73 patients were included. Among pN+ patients (n=37;50.7%), those with disease recurrence (n=16;43.2%) exhibited a higher median LNR (0.159 versus 0.060), p=0.007. ROC curve analysis showed that LNR>0.063 predicted recurrence (sensitivity 87%;specificity 48%). Moreover, multivariate analysis confirmed LNR>0.063 as an independent predictor of disease recurrence, after controlling for potential confounders, namely age, extracapsular spread, resection margin and pathological T category, (HR=6.58; p=0.049). Finally, high LNR (>0.063) was associated with cancer-specific death (OR=8.64; p=0.008) in pN+ patients. Conclusion: Our findings highlight that patients with LNR>0.063 are more likely to have aggressive disease, suggesting LNR as a significant prognostic factor complementing TNM staging in pN+ laryngeal cancer.
