Chemotherapy drugs usually succeed at killing cancer cells, but some cancers have a tendency to develop a resistance to treatment, according to a University of Wisconsin Health release.
“If a patient will not be sensitive to a treatment, they should not be placed on that treatment. They should not be over-treated,” said Dr. Wei Xu, professor of oncology at the University of Wisconsin Carbone Cancer Center and McArdle Laboratory for Cancer Research and senior author of the study. “Also, we want to give timely treatments, because if you match the patient to the right treatment, you’re more likely to save someone’s life.”
