The new blood test that detects cases of cancer patients with nonspecific symptoms

The cancer research and prevention they must remain a priority for society. Your cure Early detection of Cancer it is one of the factors that most influences its possible cure. Thanks to research, survival in Cancer It has increased by 20% over the last 20 years, but there is still much to do. Regarding early detection, scientists have successfully developed a new cancer detection testr in people with nonspecific symptoms, such as weight loss and fatigue. The best? The simplicity and effectiveness of the test.

It is the first blood test for cancer detection that also determines the metastatic stage unknown previously the origin of cancer. That is, if the disease is localized or metastatic. The publication explains how the Oxford researchers analyzed blood samples from 300 patients with nonspecific symptoms of cancer using a technique called metabolomic nuclear magnetic resonance (NMR).


NMR technology analyzes by magnetic fields and radio waves, blood levels of metabolites (any molecule used or produced during metabolism). These will be different in healthy people and those with localized or spread cancer.

” We are now beginning to understand how the metabolites produced by tumors can be used as biomarkers to detect cancer accurately “, explains Dr. James Larkin, one of the authors of the study, in statements collected by ‘Medscape’.

Different cancer treatments include chemotherapy, immunotherapy, or surgeryBut they all have their own potential side effects. That is why advance notice is important, there are patients who would benefit a lot if you could identify them earlier.

Larkin, from the University of Oxford, also commented to ‘The Guardian’ that “the problem that we have had in the past is that if people have cancer, that cancer grows all the time, and when they return, the cancers are usually quite advanced ”. ” There are likely to be tens of thousands of patients across the UK. We hope to detect these patients when they come to the GP, to give them a choice of who to send them to immediately. ”

The test was also able to determine if the patient had a cancer localized or had spread with a 94 percent accuracy, which makes it the first test capable of detecting this without knowing what type of tumor the patient has. “This information changes the way patients are treated,” said Dr. Larkin.

The blood test based on metabolomic MRI correctly detected the presence of tumors in 19 of the 20 cancer patients who were part of the study. It also identified metastatic disease in these patients with a 94% accuracy.
