Prognostic analysis of lymph node ratio of patients with disease recurrence previously submitted to cervical dissection surgery for head and neck cancer.

Introduction: the variable lymph node ratio has recently been studied as a possible influencer in the survival of patients diagnosed with head and neck cancer.

Objective: to analyze the correlation between lymph node density and survival of recurred disease patients previously submitted to cervical dissection surgery due to head and neck squamous cell carcinoma.

Method: we retrospectively analyzed 71 medical records of patients treated at the Head and Neck Surgery Service of the Pontifícia Universidade Católica de Campinas who had undergone cervical dissection surgery and presented tumor recurrence between 2006 and 2019.
