Blood transfusion might not be recommended for gastric cancer patients with pretransfusion minimum hemoglobin values higher than 90 g/l: a real-world study covering 20 years of 13 470 patients.

In our study, we analyzed the trend of PBT ratios, and we found that there was a significant trend of decreasing ratios of PBT over time, which declined from 29.1% (114/392) in 2000 to 11.2% in 2019 (149/1178), which was consistent with Ecker et al .’ 5 results, with the highest blood transfusion ratio in 2005 at 43.7% (220/504).
