1. What is the MIA Model?

The MIA (Melanoma Institute Australia) model calculates melanoma risk based on tumor thickness, ulceration status, and anatomical location. It helps clinicians assess prognosis and guide treatment decisions for melanoma patients in Australia.

2. How Does the Calculator Work?

The calculator uses the MIA risk model:

Where:

• \( Thickness \) — Tumor thickness in millimeters (Breslow thickness)
• \( Ulceration \) — Presence or absence of ulceration
• \( Location \) — Anatomical site of primary melanoma

Explanation: The model incorporates these three key prognostic factors to estimate the risk of poor outcomes.

3. Importance of Melanoma Risk Assessment

Details: Accurate risk assessment is crucial for determining appropriate follow-up schedules, adjuvant therapy, and patient counseling in melanoma management.

4. Using the Calculator

Tips: Enter tumor thickness in mm, select ulceration status and anatomical location. All values must be valid (thickness > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is considered high risk in this model?
A: Generally, scores above 20 indicate higher risk, but interpretation should be done by a specialist.

Q2: How accurate is this calculator?
A: The model has been validated in Australian populations but should be used alongside clinical assessment.

Q3: Does this apply to all melanoma types?
A: The model is primarily for cutaneous melanoma. Other types may require different assessment.

Q4: What's the most important factor in the model?
A: Tumor thickness is typically the strongest predictor, but all three factors contribute significantly.

Q5: Should this replace doctor's advice?
A: No, this is a decision-support tool only. Always consult your healthcare provider.
