Abstrakt: Background: Studies have demonstrated comparable outcomes between laparoscopic and open resection of gastrointestinal stromal tumor (GIST). We sought to compare outcomes among robotic, laparoscopic, and open resection of gastric GIST in the era of expanding minimally invasive surgery.
Methods: A retrospective analysis was performed of adult patients with gastric GIST undergoing definitive surgery using the National Cancer Database from 2010 to 2020, excluding cases converted to open. Patients were stratified into minimally invasive surgery (MIS), (combined robotic (R) and laparoscopic (L)), and open (O). Hospital length of stay (LOS), 30-day mortality, 90-day mortality, and margin status were assessed. Subgroup analysis was performed to evaluate outcomes between R and L cohorts. Entropy balancing was used to adjust for intergroup differences. Kaplan-Meier survival estimates were used to compare unadjusted 5-year survival.
Results: Of the 15,022 patients (R = 10.4%, L = 44.3%, O = 45.3%), 63.2% were stage I and 70.6% underwent partial gastrectomy. MIS approach was associated with shorter hospital LOS (β: - 2.58; 95% CI: - 2.82 to - 2.33) and lower odds of 30-day (OR 0.45; 95% CI: 0.30-0.68) and 90-day mortality (OR 0.54; 95% CI: 0.39-0.74) compared to O. Likelihood of R0 resection similar between groups (OR 1.00; 95% CI: 0.88-1.14). Hospital LOS (β: + 0.25; 95% CI: - 0.14-0.64), odds of 30-day (OR 0.99; 95% CI: 0.40-2.46) and 90-day mortality (OR 0.89; 95% CI: 0.47-1.70), and rate of R0 resection (OR 1.02; 95% CI: 0.82-1.27) were comparable between R and L cohorts. Compared to O, MIS approach was associated with improved 5-year OS (log rank p < 0.001). Overall survival was not significantly different between R and L (log rank p = 0.44).
Conclusion: These findings suggest that MIS approach may be considered for resection of gastric GIST in select patients. Among patients receiving an MIS approach, the robotic technique can be considered an oncologically safe alternative to laparoscopic surgery.
