Dr. Gralow:                

The staging of breast cancer has traditionally been by something we call anatomic staging, which has the tumor size, the number of local lymph nodes involved, and whether it has metastasized beyond the lymph nodes. So, that’s TNM – tumor, nodes, metastases. And so, that’s the classic staging, and based on combinations of those things, you can be a Stage 0 through Stage 4. Stage 0 is reserved for ductal carcinoma in situ, which is a noninvasive breast cancer that can’t generally spread beyond the breast, so that’s Stage 0, and then we go up for invasive cancer.

Interestingly, just a couple years ago, the big group that oversees the staging of cancers decided that in breast cancer, that TNM – the size, the lymph nodes, and the location beyond the lymph nodes – is not good enough anymore, so they came up with a proposal for what we call a clinical prognostic stage, which is a companion to the traditional TNM staging.

What they were getting at here was it’s not just how big your cancer is, how many lymph nodes, or whatever, it’s also at the biology of your cancer. So, this new clinical prognostic stage takes into account the estrogen and progesterone receptor of your cancer, the HER2 receptor at the grade, which is a degree of aggressiveness, and then, if your tumor qualifies, one of the newer genomic testing profiles that we use in earlier-stage breast cancer, such as the Oncotype DX 21-gene recurrence score or the MammaPrint 70-gene assay.

So, all of that goes into account now, and the whole point here is that the estrogen receptor, the HER2, the grade, and some of these genomics may actually make more difference than how many lymph nodes you have, where the cancer is, and how big it is, so it’s not just the size, but also the biology of the cancer that we’re trying to include in the new staging systems.

In this program, Dr. Gralow, we’re focusing on metastatic breast cancer. Would you explain when breast cancer is considered to have metastasized?

Dr. Gralow:                

That’s a great question because technically, if the lymph nodes in the armpit – the axillary area – are involved, that does represent spread beyond the breast, but if it stays in the local lymph node areas, it’s not technically called a metastatic or Stage 4 breast cancer. So, metastatic breast cancer would have traveled beyond the breast and those local lymph nodes, and some common sites would be to the bone, to the lungs, to the liver, less commonly – at least, up front – to the brain, and it could also travel to other lymph node groups beyond those just in the armpit and the local chest wall area as well.

Katherine:                  

What about subtypes? How are they determined?

Dr. Gralow:                

The main way that we subtype breast cancer right now is based on the expression of estrogen and progesterone receptor, the two hormone receptors, and the HER2 receptor, the human epidermal growth factor receptor. So, to date, those are the most important features when we subtype, and so, a tumor can either express estrogen and progesterone receptor or not, and it can overexpress or amplify HER2 or not, and if you think that through, you can come up with four different major subtypes, in a way, based on estrogen receptor positive or negative and HER2 positive or negative.

When all three of those are negative, we call that triple negative breast cancer, and that’s about 18-20% of all breast cancers as diagnosed in the U.S. And then, when all three are positive, we sometimes call it triple positive, and the reason that we subtype is because we know that those different subsets act differently and that we have different drugs to treat them with, and we’ve got great drugs in the categories of hormone receptor positive and HER2 positive, and increasingly, some recently hope in a new drug approval or two in triple negative breast cancer as well.

Dr. Wakelee:

So, when facing a new diagnosis of lung cancer, one of the questions that often comes up is whether one should go get a second opinion or see a lung cancer specialist. And that is a question that obviously is gonna vary quite a bit by where a person is, where they’re getting seen, and what they’re facing.

I think a time that it’s really critical would be if someone has a Stage III lung cancer or told it might be Stage III. That’s a really good time to get a second opinion and make sure that the group that is taking care of you has had a multidisciplinary discussion. And when I say multidisciplinary, I mean, a thoracic surgeon, a radiation oncologist, and a medical oncologist have altogether looked at what’s going on with the particular case of that patient to decide up front what’s gonna be the best approach.

Because sometimes surgery is the right first approach. And sometimes it’s not. And sometimes radiation’s important, and sometimes it’s not.

So, it’s really critical to have a big team looking at what’s going on for Stage III. And if you’re in a hospital that really doesn’t see a lot of Stages III lung cancer that might be a good time to think about getting a second opinion outside of where you’re being treated.

I think, otherwise, if someone is newly diagnosed and we know the cancer is early stage where surgery might be involved, it’s good to check in that the surgeons who would be doing your operation are surgeons who know about lung cancer and have done lung cancer surgeries frequently. Sometimes in smaller hospitals there are surgeons who do both heart and lung surgery. And we know that the outcomes are not always quite as good in that setting.

Sometimes there’s no choice, and that’s okay. But if there is an opportunity to talk to a dedicated thoracic surgeon who’s used to doing lung cancer surgery, that’s another good time to get a second opinion. When we’re dealing with a more advanced stage of metastatic lung cancer, if someone is newly diagnosed and their tumor ends up having an unusual gene mutation or translocation.

And the molecular changes in lung cancer are really important to know about. And things like EGFR and ALK and RAS, where most medical oncologists will be familiar. But there’re others, like BRAF and RET and MET, and those can really change treatment outcomes as well, but not everybody who sees lots of different kinds of cancer as an oncologist will know everything there is to know about those.

So, if you have an unusual gene mutation, that’s another good time to get a second opinion with someone who’s a dedicated lung cancer expert. And usually those folks are at the larger academic medical centers, so oftentimes in cities, or affiliated with universities.

Another time is if someone does have a tumor with an EGFR, ALK, or one of the more common mutations, but the main drugs have stopped working, that’s often a time where someone who has specialized just in lung cancer might have some other options.

It’s also something to think through when someone’s newly diagnosed, if they know that their doctor has looked at the immune markers like PD-L1, and looked at the genetic changes in the tumor, and has a clear plan that’s gonna involve chemotherapy, or chemotherapy plus radiation, or chemotherapy plus immune therapy.

Then there might not be something that’s gonna be different in an academic center. But before you start treatment, if you’re still feeling okay, don’t have to start treatment tomorrow, and wanna know maybe that there’re clinical trial options, that’s another time to think about getting a second opinion. And a lot of academic centers will work to get people in very, very quickly if they knew they’ve just been diagnosed and they really need to get started on treatment right away.
