Abstract

BACKGROUND: Minimally invasive surgery is associated with improved short-term outcomes and similar long-term oncologic outcomes for colorectal cancer patients compared with open surgery. Although the robotic approach has ergonomic and technical benefits, how it has impacted utilization of traditional laparoscopic surgery and minimally invasive surgery overall is unclear. OBJECTIVE: Describe trends in open, robotic, and laparoscopic approaches for colorectal cancer resections and examine factors associated with minimally invasive surgery. DESIGN: Retrospective cohort study using data from the National Cancer Database from 2010 through 2020. SETTING: Commission on Cancer-accredited U.S. facilities. PATIENTS: Patients diagnosed with nonmetastatic colon or rectal adenocarcinoma. MAIN OUTCOMES MEASURES: Surgical approach rates (open, robotic, laparoscopic). RESULTS: We identified 475,001 patients diagnosed with nonmetastatic colorectal adenocarcinoma, of whom 192,237 (40.5%) underwent open surgery, 64,945 (13.7%) underwent robotic surgery, and 217,819 (45.9%) underwent laparoscopic surgery. For colon cancer, laparoscopic minimally invasive surgery use steadily increased, with a peak prevalence of 54.0% in 2016, and total minimally invasive surgery (robotic + laparoscopic) was performed more often than open surgery from 2013 through 2020. For rectal cancer, laparoscopic minimally invasive surgery had a peak prevalence of 37.2% in 2014 and declined from 2014 through 2020; robotic surgery prevalence increased throughout the study period (5.5% in 2010, 24.7% in 2015, 48.8% in 2020). Minimally invasive surgery use increased in facilities performing robotic surgery every year during the study period. For both colon and rectal cancer, use of open surgery decreased across all facilities throughout the study period. LIMITATIONS: Utilized National Cancer Database which may not be generalizable to non-Commission on Cancer institutions. CONCLUSIONS: Minimally invasive surgery steadily increased across all facilities from 2010 through 2020. Open resections declined, laparoscopic resections plateaued, and robotic resections increased for colon and rectal cancer. Minimally invasive surgery increases may be driven by increases in robot-assisted surgery. See Video Abstract.
