Abstract
BACKGROUND: While studies have reported improved morbidity of laparoscopic (LG) compared with open gastrectomy (OG), it remains unclear whether comparable oncologic outcomes can be achieved. This study aims at comparing not only short-term outcomes, including 30- and 90-day mortality, but also survival of LG vs OG. METHODS: The National Cancer Database was searched for adult patients with histologically proven gastric cancer and complete information regarding M0 disease, tumor size, differentiation grade, T stage, nodal status, comorbidities, type of hospital, hospital stay, type of surgery, oncological treatment and survival data were included. Logistic regression analyses were performed to analyze margin status, 30- and 90-day mortality, and 30-day re-admission rate. Linear regression was performed for length of hospital stay and lymph node yield. Kaplan-Meier survival analyses were performed to evaluate median survival. Cox multivariable regression models were created to correct for confounders and identify factors affecting survival. RESULTS: A query of the National Cancer Database identified 13,538 patients with complete dataset. A significant regression equation favoring LG for lymph node yield, hospital stay, and unplanned re-admission rate was identified. There was no significant effect of surgical approach on R1 margin rate, 30-day mortality, or 90-day mortality. Median survival was comparable between LG and OG (44.8 vs 40.2 months, p = 0.804). CONCLUSION: LG offers a safe surgical approach to gastric cancer with shorter hospital stay and lower re-admission rates than OG, and also similar and sometimes improved operative oncologic quality parameters (margin, lymph node yield). More importantly, this Western series demonstrates that equivalent long-term outcomes of LG vs. OG are being achieved.
