October is Breast Cancer Awareness Month, and the disease can be more prevalent with age, which is why it's important for those in elder care to be on high alert. However, thanks to early detection and advancing medicine, the form of cancer is becoming more treatable.
According to research out of the University of Toronto, Mississauga, biological markers, which are genetic characteristics associated with some breast cancer patients, could improve the success rates for potential treatments of the disease.
The study's authors noted that using biological markers may increase the success rate for drugs by nearly 50 percent, which is something the medical community needs.
"It's been increasingly difficult for pharmaceutical companies to bring new drugs to market," said Jayson Parker, a faculty member in the Department of Biology and medical biotechnology analyst at the University of Toronto. "On average, about 80 percent of drugs fail at some point in the clinical trial process."
The study's authors compared clinical trials that used the HER2 biomarker to studies that did not. They found the success rate of drug development in HER2 was 23 percent, compared to the 15 percent that didn't use it.
