Tumour distance from midline is useful for predicting secondary lymph node metastasis in early-stage tongue squamous cell carcinoma

Key Points

• Tumour distance from midline significantly predicts lymph node metastasis, indicating a potential diagnostic marker.
• Key evidence shows that a distance greater than 1 cm correlates with a lower risk of metastasis.
• Observational analysis evaluated cases of early-stage tongue squamous cell carcinoma with a specific focus on lymph node involvement.
• The findings suggest that measuring tumour distance may inform surgical decisions and improve patient outcomes.
