ABSTRACT
BACKGROUND:
Minimally invasive techniques for gastric cancer surgery have recently been introduced in the Netherlands, based on a proctoring program. The aim of this population-based cohort study was to evaluate the short-term oncological outcomes of minimally invasive gastrectomy (MIG) during its introduction in the Netherlands.METHODS:
The Netherlands Cancer Registry identified all patients with gastric adenocarcinoma who underwent gastrectomy with curative intent between 2010 and 2014. Multivariable analysis was performed to compare MIG and open gastrectomy (OG) on lymph node yield (≥15), R0 resection rate, and 1-year overall survival. The pooled learning curve per center of MIG was evaluated by groups of five subsequent procedures.RESULTS:
Between 2010 and 2014, a total of 277 (14%) patients underwent MIG and 1633 (86%) patients underwent OG. During this period, the use of MIG and neoadjuvant chemotherapy increased from 4% to 39% (p < 0.001) and from 47% to 62% (p < 0.001), respectively. The median lymph node yield increased from 12 to 20 (p < 0.001), and the R0 resection rate remained stable, from 86% to 91% (p = 0.080). MIG and OG had a comparable lymph node yield (OR, 1.01; 95% CI, 0.75-1.36), R0 resection rate (OR, 0.86; 95% CI, 0.54-1.37), and 1-year overall survival (HR, 0.99; 95% CI, 0.75-1.32). A pooled learning curve of ten procedures was demonstrated for MIG, after which the conversion rate (13%-2%; p = 0.001) and lymph node yield were at a desired level (18-21; p = 0.045).CONCLUSION:
With a proctoring program, the introduction of minimally invasive gastrectomy in Western countries is feasible and can be performed safely.Palavras-chave
