A new study conducted by Tel Aviv University researchers suggests that the use of fresh red blood cells in transfusions for cancer patients can improve long-term survival rates, and reducer the incidence of the cancer recurrence.
Reporting their findings in the journal Anesthesiology, the researchers highlight the fact that blood transfusion during certain cancer surgeries is associated with increased cancer recurrence and reduced survival rates, but why this happens is not well understood.Dr. Shamgar Ben-Eliyahu and his university colleagues say that their study on rats may provide surprising insights that could open doors for important research in humans in the near future.
For their study, the researchers used rat models of leukemia and breast cancer to help determine whether blood transfusion is an independent risk factor for cancer recurrence/progression, and to understand what aspects of the transfusion cause the alleged harmful effects.
"The results of our study clearly indicate that blood transfusion is an independent risk factor for cancer recurrence in the animal models we used," said Dr. Ben-Eliyahu.
"But our study also yielded two surprising findings. First, the storage time of the transfused blood was the critical determinant of harmful effects: fresh blood had no harmful effects. Second, and even more surprising, we found that red blood cells, not white blood cells, caused the effects we observed," the researcher added.
The study's results also contrast the suggestion belief that white blood cells within transfused blood may be responsible for cancer progression, said Dr. Ben-Eliyahu.

He added that there seemed to be no difference in harmful effects between transfused blood taken from the same animal or from a different animal.

Dr. Ben-Eliyahu said that the findings of their study on mice indicate the need for studies in cancer patients, so that it can be determined whether alterations in blood transfusion practices can indeed improve patient outcomes.
