Why the study?
Does lung cancer surgery reduce cardiorespiratory fitness, and can postoperative V̇O2peak be accurately predicted by the number of lung segments removed?
Population
70 patients (35 women) undergoing lung cancer surgery
Comparison
Lung cancer surgery (lung resection) vs Preoperative baseline
Design
Cohort
Follow-up
4-6 weeks (and 6 months for a subset of 23 patients)

Segment-based ppoVO2peak predictions are unreliable after lung resection; leaves open need for refined models before guiding decisions.
Does lung cancer surgery reduce cardiorespiratory fitness, and can postoperative V̇O2peak be accurately predicted by the number of lung segments removed?
The reduction in cardiorespiratory fitness after lung cancer surgery is not accurately predicted by the amount of functional lung tissue removed, challenging the utility of the segment method.
