Urine Tests Now Detect Brain Tumors: Despite recent gains in cancer survival rates due in part to earlier detection of many types of cancer, the survival rate for those diagnosed with a brain tumor has remained almost stable for over 20 years. Despite recent improvements in cancer survival rates, this persists. And this is even though the overall cancer survival rate has increased dramatically in recent years.
Urine Tests Now Detect Brain Tumors
Scientists have discovered that a particular membrane protein is only detectable in the urine of people who have brain tumors. Modern technology was used in the analysis. They found that the protein used to diagnose brain cancer could one day eliminate the need for intrusive therapies and enhance the likelihood of tumors being diagnosed early enough for surgical removal.
It is suggested in the article that the research conducted at Nagoya University in Japan could be used to detect multiple types of cancer. The study’s findings were summarized and presented in ACS Nano, a peer-reviewed academic journal.
Although recent advances in cancer survival rates have been attributed in part to the earlier discoveries of many types of cancer, the survival rate for brain tumors has remained nearly stable for over 20 years. This is even though recent advances in cancer survival rates have been mostly attributable to earlier identification of many malignancies. This occurs even though the 5-year survival rate for all cancers has increased significantly in recent years.
Typically, neurological signs, including a loss of movement or the inability to express oneself verbally, prompt medical professionals to suspect a brain tumor for the first time. In many cases, the tumor will have attained a significant fraction of its maximum capacity by this point. Findings from the study suggest that lives can be saved by beginning therapy as soon as possible after a tumor is diagnosed when it is still in its earliest stages.
The results of the study raise the possibility that the presence of extracellular vesicles (EVs) associated with tumors in the urine can be used to diagnose brain tumors. There should be a citation here, but [further information is needed.]
Nanoscale vesicles called extracellular vesicles (EVs) play many roles in the body, including facilitating communication between cells. As well, electric vehicles (EVs) are already common knowledge. Based on the study’s findings, it is possible to use these to detect the existence of cancer and the advancement of the disease since they contain specialized RNA and membrane proteins that are only seen in people with brain cancer.
The study found that many of the EVs made by cancer cells make it through the excretion process in the urine without being broken down. This holds even if they are destroyed at a considerable distance from the brain. Associate Professor Takao Yasui from the Graduate School of Engineering at Nagaya University claims, “Urine testing offers a variety of advantages.” Numerous diseases can be identified through testing the patient’s urine.

Although blood tests are considered invasive, other bodily fluids can be used to do a liquid biopsy. Yasui thinks that urine testing is a good technique since it is simple, effective, and does not require any kind of invasive therapy, and this is because urine includes a high number of significant biomolecules that can be traced back to identify the problem.
Nanowires placed at the base of a well plate were used by a team led by researchers from Nagoya University to create a new analytic platform for EVs from brain tumors, as reported in the paper. The EVs were analyzed on this testing ground. Japanese academic institution the University of Tokyo collaborated on the creation of this system.
Urine samples from patients with brain tumors were analyzed to discover two distinct EV membrane proteins, CD31/CD63. Urine samples were collected from the patients in the comfort of their own homes. The study’s results show that by searching for these diagnostic proteins, doctors may be able to identify patients with tumors before they begin to exhibit any symptoms. Yasui claims that to successfully isolate and then identify EVs, current techniques require more than two instruments and an assay.
Isolating and detecting EVs with the help of a single, straightforward technique is possible with the help of the all-in-one nanowire assay. Soon, patients will be able to run samples through our assay and tailor the detection component to identify specific membrane proteins or miRNAs within EVs for the diagnosis of a variety of malignancies. This will allow for a more prompt diagnosis of the problem.
As stated by Yasui, “using this platform, we plan to progress the analysis of the expression levels of particular membrane proteins in the urinary EVs of patients,” which will enable for the early identification of certain cancers. With this, the article on Urine Tests Now Detect Brain Tumors ends.

FAQ
Are brain tumors fatal?
Nearly 36% of Americans who are diagnosed with a malignant brain or central nervous system tumor will be alive after 5 years. The average survival rate after 10 years is around 31%. Survival rates following the diagnosis of a malignant brain or central nervous system tumor are affected by the patient’s age. Teenagers under the age of 15 have a 75% chance of living for five years after being diagnosed with cancer.
