Scientists say genetic map may help in battle against deadly breast cancer

Scientists say they’ve made an unexpected discovery that will help doctors personalize treatment for one of the deadliest forms of breast cancer. A team of researchers in British Columbia, Alberta, the United States and the U.K. mapped the genetic profile of what’s called triple-negative breast cancer.
The 59 scientists involved in the study expected to see similar gene profiles when they mapped the genomes of 100 tumours. But they found no two genomes were similar. Samuel Aparicio, one of the paper’s authors who teaches at UBC and works at the BC Cancer Agency, cautioned the paper’s conclusions won’t mean quick changes for anyone in treatment for this type of cancer now.
“The main pointer here is that we will have to learn how to combine drugs from the outset, as is done in treating diseases like HIV for example, where combination therapies have become very successful.”
