Resumen:
Backgound The objective of this study is to assess a new parameter, the weighted lymph node ratio (WLNR), which incorporates prognostic information regarding the number of metastatic nodes with extracapsular spread and the lymph node yield for pN0 patients to the lymph node ratio. Methods We studied retrospectively 1118 patients with head and neck squamous cell carcinoma (HNSCC) treated with a neck dissection. Results We obtained a classification with four categories based on the WLNR values. WLNR classification had a higher prognostic discrimination capacity and a more homogeneous distribution in the number of patients included in each of the categories than the pTNM classification. Conclusion The WLNR improved the predictive capacity of the eighth edition of the pTNM classification and it can be a useful tool in the assessment of the postoperative staging of the neck dissections in HNSCC patients.
