1. What is the Post Op Risk Calculator?

The Post Op Risk Calculator estimates the postoperative risk for breast cancer patients based on age, cancer stage, and DLCO (Diffusing Capacity of the Lungs for Carbon Monoxide). It helps clinicians assess surgical risks and plan appropriate interventions.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Age \) — Patient's age in years
• \( Stage \) — Cancer stage (unitless)
• \( DLCO \) — Diffusing capacity of the lungs for carbon monoxide (%)

Explanation: The equation accounts for the combined impact of patient age, cancer progression, and pulmonary function on postoperative outcomes.

3. Importance of Risk Calculation

Details: Accurate risk estimation is crucial for surgical decision-making, patient counseling, and postoperative care planning in breast cancer patients.

4. Using the Calculator

Tips: Enter patient age in years, cancer stage, and DLCO percentage. All values must be valid (age between 1-120, stage ≥0, DLCO between 0-100).

5. Frequently Asked Questions (FAQ)

Q1: What factors does this risk calculator consider?
A: The calculator considers patient age, cancer stage, and pulmonary function (DLCO) as primary risk factors.

Q2: What are typical risk percentages?
A: Risk percentages vary widely based on individual factors. Generally, <30% is considered low risk, 30-60% moderate risk, and >60% high risk.

Q3: When should DLCO be measured?
A: DLCO should be measured preoperatively as part of pulmonary function testing, ideally when the patient is clinically stable.

Q4: Are there limitations to this calculator?
A: The calculator provides an estimate and doesn't account for all individual factors like comorbidities or specific surgical techniques.

Q5: How should the results be used clinically?
A: Results should be interpreted in conjunction with clinical judgment and other relevant patient factors when making treatment decisions.
