Trends and factors affecting approach choice to pulmonary resection.

Abstract

The development of an advanced robotic platform in 2014 led to increased adoption of minimally invasive (MI) approaches in thoracic surgery. Due to dataset reporting lag, a comprehensive assessment of trends in thoracic approaches has not been analyzed to date. We queried the National Cancer Database (NCDB) for patients with Stage I-III who underwent lung resection from 2010 to 2018. Most published NCDB analyses on lung cancer using pre-2015 data. Overall treatment trends were analyzed, with geographic, institutional, and socioeconomic characteristics evaluated for approach. There were 162 335 lung resections, and 131 958 were anatomic. Robotic resection saw a steady increase through 2012 but plateaued in 2013-2014. From 2015 to 2018, another increase correlated with the release of a new platform. Video-assisted thoracoscopic surgery lung resection plateaued in 2014 and decreased in 2018. Open resection steadily decreased. Tumors requiring neoadjuvant radiation had an increase in MI approach with corresponding decreases in the open. On multivariable analysis, African-American race, low volume, Medicaid insurance, and nonacademic setting were associated with a lower likelihood of MI surgery. The open approach has decreased since 2010. More than 65% of anatomic resections are now performed inMI. As this trend will continue, it is important that all patients are afforded the opportunity of the least invasive approach.
