Abstract: The goals of this retrospective cohort study were to compare the results of clinical and pathological TNM staging in patients with laryngeal squamous cell carcinoma and to determine the impact of the discordance on prognosis and treatment results. A total of 124 patients with laryngeal cancer, primarily indicated for surgical treatment, were enrolled. The concordance or discordance between the clinical and pathological staging was compared with the frequency of cancer relapse and disease-specific survival. Other potential prognostic factors, like age, the stage and location of the primary tumor, the status of neck lymph nodes, histological margins, and an indication for postoperative radiotherapy, were also evaluated. A disparity in at least one component of TNM staging was found in 40 patients (32%). The discordance had significant negative influence on both disease-free survival (DSF) and disease-specific survival (DSS). Other significant negative prognostic factors were the stage of the primary tumor, nodal status and postoperative radiotherapy. Our results indicate that the discordance between clinical and pathological staging affects the results of cancer treatment significantly. Some improvement can be probably achieved with higher preoperative diagnostic method accuracy.
