Autotransfusion is a process wherein a person receives their own blood for a transfusion, instead of banked allogenic (separate-donor) blood.There are two main kinds of autotransfusion: Blood can be autologously "pre-donated" (termed so despite "donation" not typically referring to giving to one's self) before a surgery, or alternatively, it can be collected during and after the surgery using ...
White blood cells may be removed to protect them from damage before high-dose chemotherapy, then transfused back into the patient, in the treatment of advanced breast cancer. [1] Another novel use of cells obtained through leukapheresis is to stimulate a patient’s immune system to target prostate cancer cells. [2]
Blood compatibility testing is routinely performed before a blood transfusion.The full compatibility testing process involves ABO and RhD (Rh factor) typing; screening for antibodies against other blood group systems; and crossmatching, which involves testing the recipient's blood plasma against the donor's red blood cells as a final check for incompatibility.
A blood substitute (also called artificial blood or blood surrogate) is a substance used to mimic and fulfill some functions of biological blood. It aims to provide an alternative to blood transfusion , which is transferring blood or blood-based products from one person into another.
A relationship between intra-operative blood transfusion and cancer recurrence has been observed in colorectal cancer. [64] In lung cancer intra-operative blood transfusion has been associated with earlier recurrence of cancer, worse survival rates and poorer outcomes after lung resection.
However, these types of transplants come at a cost of diminished graft-versus-tumor effect, greater risk of engraftment failure, or cancer relapse, [39] and general immunodeficiency, resulting in a patient more susceptible to viral, bacterial, and fungal infection. In a multi-center study, disease-free survival at three years was not different ...
Transfusion-related immunomodulation (TRIM) refers to the transient depression of the immune system following transfusion of blood products. This effect has been recognized in groups of individuals who have undergone kidney transplantation or have had multiple miscarriages . [ 1 ]
Often this occurs in people receiving cancer chemotherapy. [1] Preventive transfusion is often done in those with platelet levels of less than 10 x 10 9 /L. [2] In those who are bleeding transfusion is usually carried out at less than 50 x 10 9 /L. [2] Blood group matching (ABO, RhD) is typically recommended before platelets are given. [2]
