This study aimed to compare the postoperative morbidity, mortality, and long-term survival of patients with and without cardiovascular comorbidities (CVC) undergoing pulmonary metastasectomy (PM). The results showed that resection of pulmonary metastases can be performed safely in selected patients with stable CVC. Patients with CVC had a higher risk of postoperative complications and reduced overall survival compared to patients without CVC, but a 5-year survival rate of 68% could still be achieved.
Background: Limited information is available about the impact of cardiovascular comorbidities (CVC) on the postoperative course of patients undergoing pulmonary metastasectomy. In this study, we aim to compare the postoperative morbidity, mortality, and the long-term survival of patients with and without CVC undergoing pulmonary metastasectomy (PM).Methods: A retrospective monocentric study was conducted including 760 patients who underwent PM in curative intention. Patients were divided into two groups depending on the presence of CVC.Results: The data from 164 patients with CVC (21.6%) and 596 patients without CVC (78.4%) were investigated. In both groups, zero in-hospital-mortality and limited 30-day mortality was detected. Postoperative complications occurred more often in patients with CVC (N=47, 28.7% vs. N=122, 20.5%, P=0.02). However, most of them were minor (N=37, 22.6% vs. N=93, 15.6%, P=0.03). The presence of multiple CVC (N=18 patients, 40% vs. N=28, 23.9%, P=0.04) and reduced left ventricular function (N=5, 62.5% vs. N=42, 27.1%, P=0.03) were identified as risk factors for postoperative morbidity. Patients with CVC showed reduced overall survival (5-year survival rate: 75.8% vs. 68%, P=0.03). In the multivariate analysis lobectomy [hazard ratio (HR) 0.3, 95% confidence interval (CI): 0.1-0.8, P=0.02] and general vascular comorbidities (HR 2.1, 95% CI: 1.1-3.9, P=0.01) were identified as independent negative prognostic factors.Conclusions: Resection of pulmonary metastases can be performed safely in selected patients with stable CVC. The presence of CVC in patients undergoing PM is associated with reduced overall survival compared to patients without CVC in the long term follow up. However, a prolonged 5-year survival rate of 68% could be achieved.
