More breast cancer patients should be offered BRCA gene testing, new research shows

[joann86]

Interesting new study from the Institute of Cancer Research in London about the effectiveness of testing for the BRCA gene mutation in breast cancer patients.

"Many more people with breast cancer could get tested for mutations in the BRCA1 and BRCA2 genes under new criteria, a study suggests.

Researchers are recommending new criteria for gene testing based on simple information that is routinely available at cancer diagnosis, such as age and sex.

The study by a team at The Institute of Cancer Research, London, and The Royal Marsden NHS Foundation Trust have found that the new criteria were twice as effective at identifying people with BRCA mutations as existing criteria. They were also much simpler to use.

"

Identifying if a breast cancer is due to a BRCA gene mutation is vital to selecting the right treatments for them, and could help widen access to new precision drugs. It also gives relatives of people with mutations the opportunity to have a test to see if they are at high risk of cancer, before they get the disease.

If they have inherited the mutation they can then choose to have screening or cancer prevention surgery.

The National Institute for Health and Care Excellence (NICE) recommends that anyone with a 10% chance of having a BRCA mutation should be offered genetic testing. Very complex criteria based on family history of cancer are used to work out who reaches this 10% threshold.

In the new study, which was funded by the NIHR Biomedical Research Centre at The Royal Marsden and The Institute of Cancer Research (ICR), five simple criteria were used to decide who should be tested.

Some 1,020 people meeting the criteria were tested and 110 had BRCA mutations. If the existing family history criteria had been used only 53 of the patients with mutations would have been tested – so half of the mutations would have been missed.

Because the new criteria are so simple breast cancer patients could access testing at their cancer clinic appointment rather than having to go to a separate appointment to see if they were eligible for testing. Patients found this much easier, and it also meant the results were available much sooner."

BRCA not only gene!!! People should get tested for PALB. More aggressive. Gosh, wish Oncologists were more proactive with gene testing. If you're BRCA negative, doesn't mean anything. My sister & I were both BRCA neg & both had breast cancer. We're both positive for PALB (Partner & Locator for BRCA).

Tell your doctors!!!
