Chen et al's research provides valuable data supporting the cautious use of transfusions during gastric cancer surgery. However, to interpret causality, it must be acknowledged that recent tend-adjusted studies have consistently shown that the independent effect of transfusions may be smaller than that shown in unadjusted analyses. Future research should employ the following approaches: (1) Extended temporal characterization; (2) Functional immunological assessment; (3) Prospective designs incorporating detailed transfusion data; (4) Machine learning methods; and (5) Mechanistic studies. The relationship between transfusions and cancer treatment outcomes goes far beyond simple immunosuppression or inflammation. It reflects a complex interplay between patient vulnerability, surgical factors, and immune responses, requiring a comprehensive study across multiple biological levels and temporal dimensions.

History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
