Katherine Banwell:
What is the role of genetic and biomarker testing as screening tools?
Dr. Nita Karnik Lee:
Those two things are different in certain ways, and it’s actually really important to think about that as well because for genetic testing if you do have a strong family history, there may be times where you are going to see a cancer genetics person. They may say, hey, your mom had uterine cancer. Maybe they are diagnosed with a certain syndrome. Lynch syndrome is the most common one, which is caused by a mutation in some of the repair proteins that normally repair DNA. That’s something that can get diagnosed and predispose people to many cancers, the most common of which is colon or uterine cancer.
So, in those patients, some of those patients will actually undergo endometrial biopsies starting at a young age, even if they don’t have any irregular bleeding. Biomarkers are something also really important for somebody who is diagnosed already with endometrial cancer. So, if you get diagnosed with endometrial cancer, we actually use the biomarkers, which are an example of proteins the tumor has on its cell surface that can be turned on and off. And that profile of which biomarkers are on and off gives us an idea, and now can really help guide a little bit of treatment for some patients.
Katherine Banwell:
Okay. Should women with a family history of endometrial cancer take extra precautions?
Dr. Nita Karnik Lee:
I think they need to be really aware about the symptoms, and they need to be really thinking about whether or not there’s any role for genetic testing. Some patients, they have a family history. They’ve done genetic testing. It’s negative. There’s not anything else that we would do. But in those patients, if there’s any vaginal bleeding, spotting, anything irregular, that might really jump on the symptom diagnosis, or the symptoms leading to diagnosis, or sometimes people have other issues.
They have fibroids. They have other things going on, and maybe they need a surgery, and maybe having that family history in your background sways you a little bit more. Hey, maybe I will consider surgery. It’s probably not the only reason to do a hysterectomy, but it can contribute to the decision-making if that makes sense.
