Abstract
Abstract Background The current NCCN guidelines recommend considering elective neck dissection (END) for early‐stage oral cavity squamous cell carcinoma (OCSCC) with a depth of invasion (DOI) exceeding 3 mm. However, this DOI threshold, determined by evaluating the occult lymph node metastatic rate, lacks robust supporting evidence regarding its impact on patient outcomes. In this nationwide study, we sought to explore the specific indications for END in patients diagnosed with OCSCC at stage cT2N0M0, as defined by the AJCC Eighth Edition staging criteria. Methods We examined 4723 patients with cT2N0M0 OCSCC, of which 3744 underwent END and 979 were monitored through neck observation (NO). Results Patients who underwent END had better 5‐year outcomes compared to those in the NO group. The END group had higher rates of neck control (95% vs. 84%, p
