New Cancer Gene Test

According to a major new study, by testing for a gene that mutates in ovarian
cancers, patients could be picked out who will respond well to a promising new class of
cancer drugs. The scientists have found that defects in a gene called ARID1A caused
sensitivity to new drugs targeting the DNA repair process that is within the tumor cells.

This new drug is called ATR inhibitors and is already being tested in some early
clinical trials. The new research could help identify those patients who will most benefit.
The Institute of Cancer Research scientists in London used molecular screening
techniques to find that cancers with mutations …read more
