Abstract | PURPOSE: MATERIALS AND METHODS: A prospective cohort study was performed in 96 consecutive patients with stage T1 to T4N0M0 OOSCC (mean follow-up, 62.9 months). SLN localization was determined using cervical lymphoscintigraphy and single-photon emission computed tomography. Patients underwent SLNB examination and ND. The ND specimen was investigated by hematoxylin and eosin (H&E) staining and the SLNs were investigated using H&E staining and step-serial sectioning and cytokeratin antibodies AE1 and AE3. The statistical study calculated the sensitivity and negative predictive value (NPV). The sample size of 96 patients was calculated for a 95% confidence interval with an accuracy of ±2% and an estimated a priori sensitivity of 99% compared with the benchmark. The impact of extent of SLN involvement on the decision for ND was analyzed by χ(2) test. A logistic regression model was used to assess the association of predictor variables with SLN involvement and neck disease. RESULTS: The diagnostic accuracy, sensitivity, NPV, and negative likelihood ratio were 95%, 88%, 94%, and 0.06. The statistical comparison between the extent of metastatic involvement of the SLN and neck disease was important for SLN macrometastasis (odds ratio = 11.9), but not for SLN micrometastasis (odds ratio = 0.93).
