Establishment of a Fast-Track Gastrectomy Pathway for Patients With Gastric Adenocarcinoma at a U.S. Academic Cancer Center.

INTRODUCTION:Implementation of fast-track perioperative care pathways for gastric cancer patients in the U.S. has been challenging due to low disease incidence and limited safety and efficacy data. Our institution recently implemented such a pathway for gastric cancer patients undergoing gastrectomy, and we sought to study its effects. METHODS:We analyzed data from consecutive patients who underwent gastrectomy for gastric adenocarcinoma from January 2014 to August 2020. Patients who had surgery for recurrence, urgent surgery for obstruction, bleeding, or perforation, or an intrathoracic anastomosis were excluded. The primary predictor was whether the patient had surgery before or after implementation of a perioperative fast-track gastrectomy pathway in July 2018, and the primary outcome was length of stay. RESULTS:One hundred sixty patients were identified, 109 pre-pathway implementation and 51 post-pathway implementation. Following pathway implementation, length of stay was significantly shorter (median 6 days versus 9 days, p < 0.001), and there was no significant difference in 30-day complication rates (29% pre versus 24% post, P = 0.56) or readmission rates (18% pre versus 16% post, P = 0.85). Using linear segmented regression analysis adjusting for age, body mass index, tumor stage (early versus late), type of surgery (distal/subtotal versus total gastrectomy), and approach (open versus minimally invasive), pathway implementation was found to be associated with a 31% decreased length of stay (effect size 0.69, 95% confidence interval 0.49 - 0.98, P = 0.04). CONCLUSIONS:Fast-track gastrectomy care pathways are safe and feasible for U.S. gastric cancer patients undergoing gastrectomy and are associated with decreased length of stay.
