Measuring predicted post-operative diffusion capacity of the lung for carbon monoxide (ppoDLCO) is essential to determine patient operability and to stratify the risk of patients who are candidates for major lung cancer surgery. Studies that established surgical risk variables were based on open surgery series. The aim of our study was to analyze morbidity and mortality as a function of ppoDLCO and to compare its behavior in open and video-assisted thoracic surgery (VATS).
We compared 90-day mortality and morbidity in patients undergoing open surgery versus VATS as a function of decline in ppoDLCO. Propensity score matching (using age, ASA, arterial vascular disease, BMI, gender, stage, ppoDLCO, and ppoFEV1) was applied to create comparable open surgery and VATS groups.
Of 2,530 patients with lung cancer and ppoDLCO values, a sample of 1,624 (812 per group) was obtained after score matching. The relative risk of mortality associated with thoracotomy in patients with ppoDLCO?60 is 2.66 (p?0.02) compared to VATS. The risk of thoracotomy in terms of overall and cardiac and respiratory morbidity is higher than that of VATS for almost all ppoDLCO values.
Major resection by VATS shows lower morbidity and mortality in patients with the same ppoDLCO. A steady rise in the risk of mortality begins to occur at higher ppoDLCO values in thoracotomy (?60) than in VATS (?45).
