Margin to Depth of Invasion Ratio on Oncologic Outcomes in Node‐Negative Oral Tongue Cancer

Key Points

• This research aims to examine the impact of the margin to depth of invasion ratio on survival outcomes in node-negative oral tongue cancer patients.
• Analyzed the survival outcomes of pN0 oral tongue squamous cell carcinoma patients
• Compared patients with low and high margin to depth of invasion ratios
• Investigated recurrence risks and cancer-specific survival rates
• Patients with a low margin to depth of invasion ratio had a higher recurrence risk
• Cancer-specific survival was significantly poorer for low margin to depth of invasion ratio patients
• Indicates potential need for adjuvant treatment for high-risk subgroups
