(EMAILWIRE.COM, March 28, 2013 ) San Francisco, CA -- A new blood test will soon be able to show doctors to tailor breast cancer treatment individually, thanks to a breakthrough. Doctors hope that they will be able to save thousands of lives with the new treatment option.
Up until this newest breakthrough, medics have been forced to rely solely on scans in order to tell them whether a tumor is responding directly to therapy. Now a test developed at Cambridge University may give the physicians and specialists the earliest warning yet that the chosen approach is ineffective, and allow them to try alternative treatments sooner. Being able to switch out sooner means a possible higher rate of success given proper treatment will have more chance to take hold.
The new testing type could be available for a widespread use in less than three years, while the makers hope it will not only save or extend patients lives, but also avoid the pain and unpleasantness of undergoing certain types of treatment like chemotherapy.
Within the study from Cambridge, which was backed by Cancer Research UK and published in the New England Journal of Medicine, the researchers took regular blood samples from 30 women who were currently within advances stages of breast cancer. Researchers then looked at three markers in the blood to note if they reflected advancement or regression in the disease. One of the indicators, 'circulating tumor DNA', was rightly detected in 29 of 30 participants as changes in their cancer was identified.
The tests carried out on were relegated only to women with metastatic beast cancer. Scientists are suggesting that the same identification should work for multiple types of breast cancer, allowing for tailored, and hopefully more effective treatments.
“The main objective of the blood test is to see if someone is responding to their treatment and if not then switch them to an alternative therapy.” says Sarah Jane Dawson, who is based at the cancer research Institute.
“Hopefully this tailored approach will translate into better survival rates or in the case of those with metastatic cancer, extend their lives for as long as possible,”
“The next step is to integrate this technology into a clinical trial, she adds. “We anticipate it should be routinely used within the next two to three years.” Currently, doctors monitor the progress of treatment by using scans to observe how the cancer is responding.
