Abstract
Background
As there is no consensus on the impact of antithrombotic drugs on post-gastrectomy outcomes in gastric cancer patients, this study aimed to investigate the impact of antithrombotic drugs on postoperative outcomes in these patients after gastrectomy.
Methods
Patients with Stage I–III primary gastric cancer who underwent radical gastrectomy between April 2005 and May 2022 were included. We performed propensity score matching to adjust for patient background and compared bleeding complications. Multivariate analysis with logistic regression analysis was performed to identify risk factors associated with bleeding complications.
Results
Of the 6798 patients, 310 (4.6%) were in the antithrombotic group and 6488 (95.4%) were in the non-antithrombotic group. Twenty-six patients (0.38%) experienced bleeding complications. After matching, the number of patients in each group was 300, with insignificant differences in any factor. A comparison of postoperative outcomes showed no difference in bleeding complications (P = 0.249). In the antithrombotic group, 39 (12.6%) continued drugs, and 271 (87.4%) discontinued them before surgery. After matching, there were 30 and 60 patients, respectively, with no differences in patient background. A comparison of postoperative outcomes showed no differences in bleeding complications (P = 0.551). In multivariate analysis, antithrombotic drug use and continuation of antiplatelet agents were not risk factors for bleeding complications.
Conclusion
Antithrombotic drugs and its continuation may not worsen bleeding complications in patients with gastric cancer after radical gastrectomy. Bleeding complications were rare, and further studies are needed on risk factors for bleeding complications in larger databases.
