Introduction:
There is a dearth of literature on frailty specifically in elderly (aged ≥65 years) gastric cancer patients undergoing gastrectomy. We aim to assess the effects of frailty on postoperative outcomes.
Methods:
A review of a prospective database was performed from November 2011 to April 2019. Frailty was assessed by multidimensional frailty score (MFS). Outcomes assessed were early postoperative complications and mortality, and length of stay.
Results:
289 patients were included. The mean age was 77.3 (range 66-94) years. 183 (63.3%) were males and 172 (59.5%) had early cancer. 275 (95.2%) underwent minimally invasive gastrectomy. 79 (27.3%) patients suffered early postoperative complications, with 47 (16.3%) suffering from Clavien-Dindo grade ≥2 complications. One-year, 90-day, 30-day, and inhospital mortality were 6.6, 1.4, 0.7, and 0%, respectively. 111 (38.4%) of patients were classified as "frail" based on MFS > 5. "Frail" patients were associated with higher 1-year mortality (odds ratio (OR) 4.51, 95% CI 1.57-12.98, p = 0.005) on univariate analysis. On multivariate analysis, "frail" patients did not have significantly increased 1-year mortality. However, when definition of "frail" was changed from MFS > 5 to MFS > 6, frailty was significantly associated with increased 1-year mortality (OR 3.73, 95% CI 1.11-12.53, p = 0.033).
Conclusions:
Elderly gastric cancer patients undergoing gastrectomy with MFS > 5 do not have increased mortality risk. The influence of frailty on postoperative outcomes may vary based on the risk of the surgical procedure.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
