Impact of cervical disease and its definitive radiotherapeutic management on survival: Experience in 2013 patients with squamous cell carcinomas of the oropharynx and pharyngolarynx

Two thousand thirteen patients with squamous cell carcinoma of oropharynx and pharyngolarynx were reviewed with regard to neck disease presentation and disease‐free survival after radical radiotherapy. All patients were staged according to both the AJCC1976 and the UICC1978 classifications. Causes of failure, disease‐free survival, and complication rates were assessed. Sixty percent had a clinically positive neck. The 3‐year disease‐free survival rates were 58%, 44%, 38%, and 25% for AJCC NO, Nl, N2, and N3 cases, respectively. Corresponding UICC figures were 58%, 46%, 26%, and 29%. Analyzed parameters were nodal stage, size, site and fixity, and location of primary. Complications attributed to neck disease did not exceed 3%. A critical appraisal of the nodal staging systems is derived from these sets of data.
