Transfusion issues in the cancer patient

Area of Science:

• Veterinary Medicine
• Oncology
• Transfusion Medicine

Background:

• Blood transfusions are vital for cancer patients experiencing anemia or coagulation disorders.
• Anemia in cancer patients stems from hemolysis, blood loss, or bone marrow failure.
• Coagulation issues are frequent in cancers like hemangiosarcoma and hepatic tumors.

Purpose of the Study:

• To outline the use of blood components in veterinary cancer patients.
• To detail pretransfusion testing and monitoring protocols.
• To highlight the transient nature and risks of blood transfusions in this population.

Main Methods:

• Review of blood component therapy for anemia (packed red blood cells) and coagulation defects (fresh frozen plasma).
• Description of pretransfusion diagnostics: blood typing in cats, crossmatching in dogs and cats.
• Emphasis on continuous patient monitoring during and after transfusions.

Main Results:

• Packed red blood cells are the primary treatment for anemia.
• Fresh frozen plasma addresses disseminated intravascular coagulation and other coagulopathies.
• Platelet and neutrophil transfusions are rarely utilized despite potential indications.

Conclusions:

• Blood transfusions are essential supportive care in veterinary oncology.
• Appropriate component selection and pretransfusion testing are critical.
• Vigilant monitoring is necessary to manage transfusion-related adverse events effectively.
