Drugs like cisplatin that break DNA are some of the strongest weapons we have against breast, ovarian and other cancers. The problem, common to every form of chemotherapy, is that cisplatin doesn’t work for everyone. Given the potential side effects that go along with the drug—including vomiting, hearing loss and muscle cramps, just to name a few—the decision to give it to a patient becomes something of a gamble: Does the benefit outweigh the risk?
There are tests that examine individual genes and which can give doctors a limited view as to which tumors might respond best to cisplatin. But a multicenter team co-led by Zoltan Szallasi, MD, of Boston Children’s Hospital’s Informatics Program (CHIP), thinks they may have a solution that looks beyond individual genes to see which tumors might succumb to cisplatin and other drugs like it.
