Predictors of nodal metastasis in thin tongue tumours (depth of invasion <5 mm) – revisited

Key Points

• Nodal metastasis is influenced by the depth of invasion in tongue tumours, suggesting a critical relationship.
• Significant depth of invasion threshold identified as 5 mm, impacting clinical decisions and treatment strategies.
• Observational analysis employing clinical and pathological data from tongue cancer cases to identify predictors.
• Implies deeper understanding needed for staging thin tongue tumours; further validation in larger cohorts is encouraged.
