1. What is the MIA Melanoma Model?

The MIA (Melanoma Institute Australia) model estimates life expectancy for melanoma patients based on stage at diagnosis, age, and sex. It provides personalized survival estimates to help guide treatment decisions and patient counseling.

2. How Does the Calculator Work?

The calculator uses the MIA model equation:

Where:

• \( Stage \) — Melanoma stage (1-4)
• \( Age \) — Patient's age in years
• \( Sex \) — Biological sex (male/female)

Explanation: The model incorporates population-based survival data adjusted for individual prognostic factors.

3. Importance of Life Expectancy Estimation

Details: Accurate life expectancy estimation helps clinicians and patients make informed decisions about treatment options and follow-up care.

4. Using the Calculator

Tips: Enter melanoma stage, patient's age in years, and select sex. All values must be valid (age between 1-120).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the MIA model?
A: The model has been validated in large patient cohorts with good predictive accuracy, though individual results may vary.

Q2: Does this account for treatment effects?
A: The model provides baseline estimates that may need adjustment based on specific treatments and response.

Q3: What are typical life expectancies by stage?
A: Early stage (1-2) melanoma often has excellent prognosis, while advanced stages (3-4) have reduced but improving survival.

Q4: Are there limitations to this model?
A: The model may be less accurate for very young or old patients, and doesn't account for all individual risk factors.

Q5: Should this replace clinical judgment?
A: No, this is a decision-support tool that should be used in conjunction with clinical evaluation.
