Summary
Enter Breslow thickness and ulceration status to get AJCC 8th edition T-stage, SLNB recommendation, and survival estimates.
How it works
- Enter the Breslow thickness in millimeters from the pathology report.
- Select whether ulceration is present or absent.
- Optionally enter the mitotic rate (mitoses per mm²) if reported.
- The tool computes the AJCC 8th edition T-stage (T1a through T4b).
- SLNB eligibility threshold and 5-year survival estimates are displayed.
Use cases
- Quickly cross-check pathology T-stage from Breslow depth during case review.
- Determine whether a patient crosses the SLNB eligibility threshold.
- Understand how ulceration upgrades T-stage (e.g., T1a → T1b).
- Look up population-level 5-year survival data for patient counseling.
- Educate medical students on AJCC melanoma staging criteria.
- Compare staging across multiple hypothetical thickness values.
