초록

Backgrounds : To evaluated the use of FDG PET/CT for the identification of extracapsular spread(ECS) with histologic correlation in laryngeal cancer. Methods : We reviewed 79 medical records of patients who underwent of FDG PET/CT for laryngeal cancer before surgery. Results : ECS was present in 41.9%(18/43) dissected necks and in 34.5%(20/58) dissected cervical levels. There was a significant difference in the SUVmax between cervical lymph nodes with ECS and without ECS($6.39{\pm}4.53$ vs. $1.19{\pm}1.64$, p<0.001). The cut-off value for the SUVmax for differentiating with ECS from without ECS was 2.8 with the sensitivity of 85.7% and the specificity of 85.6%. Conclusion : The median SUVmax cut-off values of FDG PET/CT higher than 2.8 was associated with greater risk cervical lymph node metastasis with ECS in patients with laryngeal cancer.
