Another fresh Blood development Studies show that people with cancer and blood type O, such as types A, B, and AB, are at increased risk of developing venous thromboembolism (VTE), or bleeding in the veins, three months. after diagnosis. Scientists have long been trying to understand the risks to VTE, the leading cause of hospital death in the United States. Statistics have been using factors such as the type or type of cancer to identify those at risk for VTE. However, the majority of patients without these diseases still develop life-threatening blood clots but have not been diagnosed.

VTE includes deep vein thrombosis (DVT), blood clots that are usually found in the deep veins of the feet, and huhu embolism (PE), a life-threatening condition that occurs when a blood vessel breaks down and remains in the arteries of the lungs. While following bleeding can affect anyone, research shows that those with O blood type are more likely to develop VTE. Anti-cancer drugs also increase the risk of developing hypertension, and while people with a more severe form of cancer may develop VTE, less research has been done about the risk among cancer patients. tumors unrelated to thrombosis.

In the study, researchers investigated the role that non-O blood types play in participants’ potential for VTE enhancement. They collected data from 1,708 adult participants with new or recurrent cancer from the Vienna Cancer and Thrombosis Data Center (CATS). Researchers included participants for the first time blood typethen they are listed according to their own additive division. Patients with pancreatic, gastroesophageal, and brain tumors are considered to be at higher risk. While this type of virus can be useful in identifying people who may develop VTE, many people with low blood pressure are still experiencing high blood pressure, and therefore may need more. medical care. The results of the study suggest that blood pressure may be an important predictor of predictability.

“We know the type of virus helps determine the exact risk of VTE. But we continue to see that these risk factors fail to catch all cancer patients who develop these blood cells,” said study author Cornelia Englisch, MD- Ph.D. a student at the Medical University of Vienna. “By simply identifying the type of supplement, we lost about 50% of the people who developed VTE.”

Their results showed that patients with non-O blood type were more likely to develop VTE at three months after diagnosis of cancer or recurrence of cancer. According to Dr. Englisch, this group did not appear at the time of diagnosis because cancer treatment increases the risk of developing high blood pressure, which makes blood type less important than VTE in the early stages of treatment. Those with tumors outside the range of risk factors with O blood type are more likely to develop hypertension over time, suggesting that only depending on the type of cancer to detect the risk of VTE may cause many patients to fall into dislocation.

Dr. Englisch notes that while the story is, these are research findings and still need further research. Going forward, the researchers also aim to understand the biological mechanisms underlying these studies. They hope that blood pressure could be a useful tool in risk assessment for self-contained VTE in the future.

“Blood pressure is easy to implement, can be performed all over the world, and does not require any expert knowledge or equipment,” said Dr. Englisch. “And of course, every risk we take helps us understand these life-threatening conflicts cancer patients the best. “Perhaps this will raise awareness about the role that blood types can play as biologists.”


Studies have found an increased risk of developing severe blood clots up to six months after COVID-19
