Discrepancy between clinical and pathological staging of laryngeal carcinoma: a dilemma to be solved

Abstract

Abstract Objectives The aim of this study was to investigate the degree of discrepancy between the clinical and pathological staging of laryngeal carcinoma, and the potential impact of this discrepancy on the outcomes and prognosis. Methods This study was conducted on 127 patients who underwent total laryngectomy over five years (October 2016–October 2021). Data collected from pretherapeutic clinical staging regarding the extent of the tumor affection of different laryngeal subsites was compared to the postsurgical pathological assessment. Results Overall, 12 out of 127 patients (9.4%) in the current study, were clinically over-staged from T3 to T4 due to radiological diagnosis of tumor infiltration of laryngeal cartilages that proved pathologically to be free of tumor. Additionally, discordance in the N stage was found in 12.6% (n = 16). However, stage discrepancy did not have a significant impact on the prognosis and survival. Conclusion Discordance between clinical and pathological TNM staging of laryngeal carcinoma may affect the decision making and the choice of the treatment options. Some improvement can be probably achieved with advancements and higher accuracy of the preoperative diagnostic tools.
