Purpose: The aim of the study was to assess the prognostic capacity of the recently described weighted lymph node ratio (WLNR) in patients with head and neck squamous cell carcinoma (HNSCC) who undergo salvage neck dissection for regional recurrence.

Material And Methods: We retrospectively studied 197 adult patients with head and neck squamous cell carcinoma treated with salvage neck dissection from 1990 to 2017.

Results: The mean value for the WLNR for all patients was 26.

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.

Introduction And Objectives: Lymph node density or lymph node ratio (LNR), defined as the quotient between the total number of positive lymph nodes and the total number of dissected lymph nodes, has demonstrated a prognostic capacity in several tumour models, including patients with head and neck squamous cell carcinomas (HNSCC). The aim of the present study is to analyse the prognostic value of LNR in a wide cohort of patients with HNSCC.

Methods: We carried out a retrospective study of a cohort of 1,311 patients with HNSCC treated with unilateral or bilateral neck dissections.

Background And Objective: Different studies performed in populations with a high incidence of HPV infection have found no prognostic capacity of clinical nodal involvement (cN+) in patients with HPV-positive oropharyngeal carcinomas. The objective of this study was to assess the prognostic ability of nodal involvement in patients with oropharyngeal carcinomas according to HPV status in a cancer population with a low incidence of HPV infection.

Material And Methods: Retrospective study of a cohort of 420 patients with oropharyngeal carcinomas treated during the period 1990-2016 for whom information on HPV status was available.

Objective: To analyse the incidence of appearance of second and successive neoplasms in a cohort of head and neck squamous carcinoma patients.

Material And Methods: We conducted a retrospective study with 4,458 patients with an index tumour located in the head and neck diagnosed during the 1985-2016 period. We evaluated the incidence of appearance of second neoplasms and successive neoplasms over a period of 30 years.
