Gastric adenocarcinoma location and postoperative complication rates in Asian patients: A 2014-2019 NSQIP analysis.

BACKGROUND

Asian gastric cancer patients have higher long-term survival rates post-gastrectomy. This study compares 30-day post-gastrectomy outcomes between Asians and non-Asians.

METHODS

Gastric cancer patients undergoing elective gastrectomies were identified in 2014-2019 NSQIP datasets (n ​= ​1,438). Demographics, comorbidities, and postoperative outcomes were analyzed.

RESULTS

Asians had lower odds of total gastrectomy (AOR ​= ​0.52, p ​= ​0.003), age ≥65 (AOR ​= ​0.60, p ​= ​0.006), smoking history (AOR ​= ​0.35, p ​< ​0.001), dyspnea (AOR ​= ​0.25, p ​= ​0.01), and hypoalbuminemia (AOR ​= ​0.62, p ​= ​0.025); they also had lower BMI (p ​< ​0.001). Postoperative outcomes were not significantly different aside from a shorter median length of hospital stay in days (LOS) (Asians: 7 (6, 11); non-Asians: 8 (6, 11); p ​< ​0.001).

CONCLUSIONS

Asian gastric cancer patients have significantly lower odds of having select preoperative comorbidities and have shorter hospital LOS.
