> A blood test for the diagnosis of tumors in children

One of the problems related to cancer treatment is the diagnosis. This last one può take weeks, even months, before a doctor performs a biopsy and invasive techniques to confirm the suspicion of a tumor.

During this waiting period, the condition of the patients may continue to worsen. But a recent study has brought science a step forward towards the use of a simple blood test for making the diagnosis. A realityà, it seems very close to you, that you willà to develop with the discovery of “fingerprint” unique and specific for various types of tumors.

The study, which will beà presented at the National Institute for Cancer Research Cancer Conference in Liverpool, England next week, has identified a fingerprint of molecular only for 11 types of cancers in children.

The team of scientists at the Università of Cambridge and Addenbrooke’s hospital, Cambridge, have analysed blood samples of the children to whom it was già been diagnosed with cancer.

In these samples, the team identified micrornas, molecules that turn the genes, which have allowed us to identify the changes to più common linked to different cancers.

although more research is needed, the discovery of these footprints may lead to diagnosis through blood tests.

“The use of a blood test instead of surgery to remove a tumour sample could improve diagnosis-such results have in a few hours instead ofé in days or weeks,” said Matthew Murray, one of the coordinators of the study.

The Team of the scholars of Cambridge is not the only to study the use of the examination of the blood in the field of oncology. The same scientist from Hong Kong, who invented a blood test for pregnant women to check whether their children have Down syndrome, is now committed to extending the methodology to the world of cancer.

Are, however, various researchers who are studying the way to develop a blood test for cancer screening, however, the study of Cambridge lights up the interest to the fingerprint identification of the cancer for 11 different forms of childhood cancer.

In particular, scientists have found a fingerprint that has identified different types of neuroblastoma, a form of childhood cancer.

The scientists who participated in the study describing the discovery as “very exciting”, but they also stressed the needà of further research before this test can be made available to the public.
