Cancer Treatment for People with Inherited Mutations

Inherited mutations may affect treatment options or eligibility for clinical trials studying which treatments work best. The following are examples of situations where a mutation may affect cancer treatment decisions. 


Targeted therapies for advanced cancers

PARP inhibitors are a type of that work by blocking a protein used to repair damaged . People with a mutation who have been diagnosed with cancer may want to ask their doctor about whether they might benefit from a clinical trial or treatment with a

PARP inhibitors for treating prostate cancer

The , Lynparza () has FDA-approval to treat , in people who have a mutation in or other genes linked to a certain type of  damage repair. 

PARP inhibitors for advanced ovarian,  or primary peritoneal cancer

Several PARP inhibitors have been approved to treat ovarian cancers at different stages of the disease. In some situations, a tumor known as an  test ("hemologous recombination deficiency") can help identify which ovarian cancers may respond to treatment with a .
