Outcomes of surgery for lung cancer in patients with atrial fibrillation as a preoperative comorbidity: a decade of experience at a single institution in Japan.

Abstract

To investigate the surgical outcomes of surgery for non-small cell lung cancer (NSCLC) in patients with atrial fibrillation (AF) as a preoperative comorbidity. Among 805 patients who underwent surgery for NSCLC, 27 (3.4%) had a history of AF. We analyzed the perioperative and long-term outcomes of these 27 patients. Fourteen patients (52%) had chronic AF and 13 (48%) had paroxysmal AF; being high rates of a comorbid illness. Nineteen patients (70%) underwent lobectomy, and 8 (30%) underwent sublobar resection. Ten patients (37%) received perioperative heparinization. There was no mortality. Other non-AF postoperative complications developed in 8 patients (30%), this incidence being higher than among the patients without AF (16%, 127 out of 778, p=0.09). A thromboembolic event occurred in one patient (4%). With respect to the long-term outcomes, the 5-year overall survival and disease-free survival rates among the patients with AF were 70.3 and 60.8%, respectively, which were similar to those in the patients without AF (79.8 and 72.6%, p=0.30 and 0.31). Lung cancer surgery in patients with AF is safe and provides favorable long-term outcomes; however, thoracic surgeons should monitor these patients carefully for postoperative thromboembolic events.
