Abstract
Previous studies have highlighted important biologic and survival-related differences among men and women with non-small cell lung cancer (NSCLC). However, differences in perioperative or short-term outcomes have not been as well characterized. In this study, we investigated differences in the perioperative period and postoperative emergency department (ED) visits among men and women after lobectomy for stage I NSCLC. A retrospective review was performed of patients who underwent a lobectomy for clinical stage I NSCLC at a single institution from 2010 to2015. We identified 559 patients for inclusion, including 293 women (52%) and 266 men (48%). Women were more likely to present with clinical T1 status (p= 0.005) and to undergo a minimally invasive operation (p= 0.058). To reduce confounding, 206 case-matched pairs were identified. After matching, no differences were found in length of stay (p= 0.551) or pulmonary complications (p= 0.509); however, men experienced more cardiac complications (18% versus 7%, p= 0.001). Of importance, although rates of 30- and 90-day ED visits between sexes were similar (p= 0.531, p= 0.890, respectively) and no sex-related differences were found in presenting symptom on return to the ED (p= 0.478), women were more likely to be readmitted after presenting to the ED within 30 days (p= 0.038). Women demonstrated an increased likelihood of being admitted after presenting to the ED within 30 days after discharge, indicating important differences between men and women in the short-term period after lobectomy. Further research will be required to further understand the cause for these differences.
