We often hear the term precision oncology. What exactly does that mean? 

Dr. Ramaswamy:

So, precision oncology is again, one of the ways that we are getting better, right? So, what we are trying to understand is that originally, we just understood cancer as just where all it is and how spread it is. Again, an anatomical. Now we are getting more and more into the biology. So, in the biology we were focusing more on the RNA. There are two things, the RNA and DNA. DNA is your code, and RNA is the one that comes from the DNA kind of the message that goes, makes the protein, which changes everything in your body. So, we were focusing on the RNA, which are the biomarkers, right? Because we – you that that’s what drives the cancer. Now we are focusing more on the DNA. What is changing within the core, that blueprint in the tumors that is causing resistance that is making cancer cells worse?  

Could we target those? And so that is what is precision oncology. They’re trying to understand the genetic core change within your tumor and maybe able to target that. You could have breast cancer, you could have a completely different cancer like lung cancer. But if you have the same genomic change or gene change within the tumor, could we just target that cells and be able to get a really good response? And those are the kind of ways we are going towards. And I can tell you it is as you hear this concept, it sounds like so bizarre. I’ll tell you, I felt the same too when it all started, even as a scientist and an oncologist. But it is truly becoming a reality. And in certainly in more some cancers more than the others, but it’s slowly becoming a reality for all cancers. So definitely, again, a positive and a tailored therapy to the patient. And so that’s what we want.

How do biomarker test results impact prognosis? 

Dr. Ramaswamy:

All of them do because it’s important to understand that that’s why this – these biomarkers carry a lot of weight. Biomarkers are good, are important, but when the most important biomarkers are that are going to impact outcomes. And then even more important is whether they’re going to predict the efficacy of a treatment, the outcomes used by the success of a treatment, right?  

So, in that way, if your tumor is estrogen and progesterone receptor- positive, then you generally tend to do a little bit better. And they are slightly better tumors for sure, and you know that the anti-estrogens would work. So, these – there’s two ways. They are prognostic and predictive. Now, the whole two positive tumors previously used to have a worse prognosis, but we have such wonderful anti HER2 therapies now that we can use. Now we know that if you use those therapies, the outcomes are better.   

So, it’s predictive again, that predictive of the treatment and prognostic. Now the triple negatives are usually a little bit more difficult to treat because as you can understand, they don’t have any of these targets for us to use targeted therapy at this point. There is definitely some improved outcomes using immunotherapy, but you know that we don’t have those proteins. So, slightly worse outcomes for sure, triple negative among all of these subtypes. And also there is no biomarkers.  

We do use immunotherapy, which is helping certain percentage of those patients, but we still need to understand why it’s not helping other people. So, yeah.

Katherine: 

Patients are often confused about the difference between hereditary genetic testing and biomarker testing. Would you explain the difference? 

Dr. Ramaswamy:

Absolutely. So, the hereditary genetic testing is what are the genes that you got from your parents? It could be mother or father. And we all think that because it’s breast cancer should be just from mother. It doesn’t matter. It can be from mom or dad. And that influences your breast cancer risk. So, if you have some mutations or some changes in certain genes that can increase your risk of breast cancer. And the well-known ones are the BRCA1, BRCA2, but we also now know a few more like the PALB, ATM and CHEK2 and other things.  

So, now when you do have a family history, or sometimes even based on your age and your oral history, we do test for this hereditary risk factors that you might have and that may influence your surgery and some type of treatments that we give as well.  

Now as far as biomarkers, biomarkers are more proteins that we check in your tumors. The breast cancer that you already have, and that we may do the biopsies. We look for these tumor proteins that influences the growth of your cancer cells. So, we can target these biomarkers and decrease the growth of your cancer cells.
