    Summary

    Optimizing lung function through medical treatment and exercise can reduce risks associated with lung resection surgery. Careful patient selection using predictive tests is crucial for minimizing morbidity and mortality, balancing surgical benefits against potential long-term harm.

    Area of Science:

    • Pulmonary Medicine
    • Thoracic Surgery
    • Critical Care

    Background:

    • Lung resection surgery carries significant risks of morbidity and mortality.
    • Patient-specific factors like age and gender are immutable, but physiological factors can be optimized.
    • Pre-existing conditions such as COPD and asthma require careful management.

    Purpose of the Study:

    • To identify modifiable risk factors for lung resection surgery.
    • To explore strategies for optimizing patient lung function preoperatively.
    • To discuss methods for accurate risk assessment and patient selection.

    Main Methods:

    • Review of identified risk factors for lung resection.
    • Assessment of lung function optimization strategies: bronchodilators, corticosteroids, antibiotics, inspiratory muscle training.

  • Evaluation of preoperative risk stratification tools: lung scanning, CT scans for predicted postoperative functions (FEV1%, DLco%), and exercise testing (cardiopulmonary exercise testing, stair climbing).

    • Main Results:

    • Optimizing lung function and encouraging smoking cessation can mitigate surgical risks.
    • Predictive postoperative function tests (FEV1%, DLco%) and exercise tests aid in patient selection.
    • No single test definitively answers individual risk assessment; a combination of clinical judgment and data is necessary.

    Conclusions:

    • Preoperative optimization of lung function and careful patient selection are key to reducing morbidity and mortality after lung resection.
    • Balancing the potential cure against the risks of disability or death is essential in high-risk surgical candidates.
    • The decision-making process requires integrating scientific data with clinical expertise.
