  • Title: Weighted lymph node ratio: New tool in the assessment of postoperative staging of the neck dissection in HPV-negative head and neck squamous cell carcinoma patients.

    Journal: Head Neck; 2020 Oct; 42(10):2912-2919. PubMed ID: 32588930.
    Abstract:
    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.
