Introduction

Blood transfusion in advanced cancer patients can be beneficial, but may also lead to adverse reactions. Advanced cancer can cause symptoms such as hematemesis, hemoptysis, and melena, resulting in severe anemia or thrombocytopenia. Transfusion helps increase red blood cell count, improves oxygen delivery to tissues and organs, and alleviates discomfort. However, some advanced cancer patients have weakened immune systems, making them susceptible to hemolytic or allergic reactions following transfusion.

Transfusion in advanced cancer patients can be beneficial, but may also lead to adverse reactions. The specific analysis is as follows:

Patients with advanced cancer may experience symptoms such as vomiting blood, coughing up blood, or bloody stools, which can easily cause severe anemia or thrombocytopenia. Blood transfusion can help increase red blood cells, improve oxygen supply to tissues and organs, and alleviate these symptoms. However, due to decreased immunity in some advanced cancer patients, transfusion may trigger hemolytic or allergic reactions, manifesting as itching, laryngeal edema, and, in severe cases, shock.

It is recommended to carefully consider the patient's overall health status, disease progression, potential side effects, and risks, and to proceed with transfusion therapy under the guidance of a physician.
