A high prevalence of postoperative complications is closely associated with a worse short- and longterm outcome. This current study aimed to investigate potential risk factors including albumin-to-fibrinogen ratio (AFR) for severe postoperative complications (SPCs) in surgical gastric cancer (GC) patients. | Preoperative albumin-to-fibrinogen ratio predicts severe postoperative complications in elderly gastric cancer subjects after radical laparoscopic gastrectomy
