Background We evaluated the use of fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT for the identification of extracapsular spread (ECS) with supporting histologic correlations in laryngeal cancer. Methods We reviewed the medical records of 89 patients with laryngeal cancer who underwent FDG PET/CT before surgery. Results ECS was present in 38.2% (18 of 47) of dissected necks and in 32.2% (20 of 62) of dissected cervical levels. There was a significant difference in the standardized uptake value maximum (SUV max ) between cervical lymph nodes with and without ECS (6.39 ± 4.53 vs 1.21 ± 1.70; p < .001); the cutoff value for differentiating nodes with ECS from those without ECS was 2.8, with a sensitivity of 85.7% and specificity of 85.6%. Conclusion A median SUV max cutoff value >2.8 was associated with an increased risk of cervical lymph node metastasis and ECS in patients with laryngeal cancer. © 2014 Wiley Periodicals, Inc.
