Objective To evaluate the efficacy of sentinel lymph node biopsy (SLNB) in cT1/2N0 minor salivary gland cancer (mSGC) located within the oral cavity. Methods A retrospective analysis was conducted on patients diagnosed with cT1/2N0 oral mSGC, who were categorized into two groups based on neck management approaches. The impact of SLNB versus observation on regional control and overall survival was assessed using a Cox model. Results A total of 177 patients were included in the study, with 53 cases undergoing SLNB. All patients had at least one sentinel lymph node, with the majority having two sentinel lymph nodes. The sentinel lymph nodes were predominantly situated in level I, followed by level II. Four patients had positive sentinel lymph nodes, all of whom had primary tumors in the tongue or the floor of the mouth, and were classified as cT2 stage. This yielded a sensitivity and specificity of 100%, a false negative rate of 0%, and a negative predictive value of 100% for SLNB in predicting occult metastasis. In terms of regional control, SLNB exhibited a reduced hazard ratio of 0.90 (95% confidence interval: 0.64–0.96) compared to observation. However, SLNB did not confer a superior overall survival benefit compared to observation. Conclusion In patients with cT1/2N0 oral mSGC, SLNB proved to be both technically feasible and oncologically safe. When contrasted with observation, SLNB was associated with enhanced regional control, particularly recommending its use for cases of cT2 mSGC arising from the tongue or the floor of the mouth.
