Summary
Cancer patients show increased red blood cell aggregation. This study in lung and head/neck cancer patients found significant changes in erythrocyte aggregation parameters, indicating a notable intensification of this process.
Area of Science:
- Oncology
- Hematology
- Biophysics
Background:
- Red blood cell aggregation, a biophysical process, is influenced by various physiological and pathological conditions.
- Alterations in erythrocyte aggregation have been observed in several diseases, suggesting its potential as a diagnostic or prognostic marker.
Purpose of the Study:
- To investigate reversible erythrocyte aggregation in patients diagnosed with advanced lung cancer (stages III-IV).
- To examine reversible erythrocyte aggregation in patients with head and neck tumors (stages II-III), including cancers of the tongue, larynx, and buccal mucosa.
- To quantify specific parameters of red blood cell aggregation in these cancer patient cohorts.
Main Methods:
- Studied reversible aggregation of peripheral blood erythrocytes using photometric methods.
- Analyzed parameters including minimal and maximal aggregate stability (U0, Ud), aggregation half-period (tau), photometric signal amplitude (A), aggregation index (Ia), and integral coefficient (K).
Main Results:
- Demonstrated a significant intensification of reversible red blood cell aggregation in cancer patients.
- Observed a significant increase in U0, Ud, A, Ia, and K values.
- Recorded a significant decrease in the tau (red cell aggregation half-period).
Conclusions:
- Reversible erythrocyte aggregation is appreciably intensified in patients with stages III-IV lung cancer and stages II-III head and neck cancers.
- The observed changes in aggregation parameters (increased stability and index, decreased half-period) highlight altered red blood cell behavior in cancer.

02:45Blood Transfusion and Agglutination
Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
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...

01:14Erythropoiesis
Red blood cells (RBCs) transport oxygen to all body tissues. These cells survive only for 120 days and then need to be replenished. Erythropoiesis is the process of RBC production. In healthy individuals, erythropoiesis ensures all tissues are amply supplied with oxygen. In addition, blood loss due to injury leads to a drop in the physiological oxygen level that will cause erythropoiesis. Any defect in erythropoiesis leads to several physiological disorders, including thalassemia, anemia, and...
01:22Lifecycle of Erythrocytes
Erythrocytes, also known as red blood cells, constantly move through blood capillaries. As a result, they damage their plasma membrane due to the continuous friction. Typically, after 100 to 120 days, erythrocytes become rigid and fragile as they wear out. As they pass through small vessels in the spleen and liver, they can get trapped and break apart into fragments.
The resident phagocytic macrophages deal with these damaged cells by engulfing them and separating their globin and heme groups.

01:27Disorders of Erythrocytes
Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

01:10Blood Typing
Understanding an individual's blood group is a critical component of transfusion medicine. It ensures compatibility in blood transfusions, organ transplants, and even during pregnancy. Determining these blood groups involves the ABO and Rh blood typing systems, utilizing specific antigens and corresponding anti-sera to identify an individual's blood type.
Antigens are protein molecules that reside on the surface of red blood cells (RBCs). The ABO and Rh blood typing systems target antigens A,...
