Purpose: The purpose of this study is to determine the relation between the positron emission tomography/computed tomography (PET/CT) findings and post-operative pathology findings, which is a guiding characteristic for staging in patients with larynx cancer.

Materials and Methods: In order to evaluate the PET/CT in terms of diagnostics, preoperative PET/CT was applied to the patients who received laryngectomy ± neck dissection in 2013 - 2015 period. The specimens were examined in pathological terms, and the relation between the preoperative PET/CT and pathology findings of the tumor was investigated. The statistical analysis of the data was made with the NCSS 2007 computer program.

Results: The mean age of the patients who were included in the study was determined as 62, and the gender discrimination was as follows; 47 males and 3 females. A statistically significant difference was determined in the PET/CT (Mass - SUVmax) levels of the different groups of T (TNM) staging (p < 0.05); in which, the PET/CT (Mass-SUVmax) levels of the T4 subgroup were higher than those of T1-2 subgroups at a significant level (p = 0.015). Considering the tumor differentiation in histopathology, no statistically significant differences were detected between the PET-CT (Mass -SUVmax) levels of the tumors with various differentiations (p > 0.05).

Conclusion: The imaging methods used in larynx staging and in determining the treatment plan are inadequate. The use of PET/CT may change the proper surgical planning in terms of the staging of the disease.
