So, breast cancer patients have the option to remove their whole breast, which is called a mastectomy. And if they pick that option, they could choose to have reconstruction or to essentially go flat. Yes, we have even done reconstruction in metastatic breast cancer patients. Metastatic breast cancer patients live for a really long time, so giving them reconstruction to make them feel whole and kind of put them back together after a mastectomy is definitely a good option.        

The other option is to just remove the cancer. So, if the patient has a small breast cancer, and it’s metastatic, we can just say – Hey, you don’t have to have the whole breast removed. So, we can do a lumpectomy, as well.

So, a lumpectomy is essentially a surgery that removes the cancer with a normal rim of tissue around it. We also call it a partial mastectomy, meaning you’re removing just part of the breast. Or it’s also called breast-conserving surgery. So, it’s any method that removes that cancer with a normal rim of healthy tissue around it but allows the woman to keep her breasts.

So, when it comes to surgical choices and a cancer coming back, some women think that if they pick the most advanced surgery, such as a mastectomy, it helps prevent cancer from going somewhere else in the body. And that’s actually not true. Removing both breasts, doesn’t make you live one day longer. At that point, a mastectomy or a lumpectomy is a choice.

And prognosis – meaning whether or not the cancer’s gonna show up somewhere in the body – is based really on two things – the stage at which the breast cancer presents itself and what type of breast cancer it is – meaning is the cancer outside of the lymph nodes? How large is it? And if it’s a triple negative or some other type of breast cancer? Those determine the higher likelihood that somebody could develop metastatic breast cancer later in their life, even though small, early-stage breast cancers, unfortunately, can also develop metastasis later on in life.

But women sometimes think that if they pick the most aggressive surgery, it’s helping prevent metastatic spread later on in life. And that’s actually not the choice.  Breast cancer surgery is the option that women choose to surgically remove their breast cancer. But again, choosing a mastectomy or a lumpectomy for an early-stage breast cancer is a choice of how they wanna remove the breast cancer. But it doesn’t improve the chances that they won’t have metastatic spread later on.

So, the role of surgery for metastatic breast cancer is mainly for what we call to remove the cancer or sometimes for local control. So, the number one treatment if somebody is diagnosed with metastatic breast cancer is systemic therapy. That might be chemotherapy or endocrine therapy. But it’s really to get the metastatic disease under control.

So, where does breast cancer usually go? Bones, liver, lungs, brain. So, surgery to remove the breast or the breast cancer in the breast doesn’t really take care of those problems. But a lot of times for metastatic cancer, the one reason would be for local control. So, if the cancer is causing issues in the breast – swelling, coming out of the skin – where it’s a wound issue, then we’ll remove that to get better control of the area in the breast.

The other reason is if somebody has metastatic cancer, and their cancer in the other area of their body is controlled with the therapy, then we say – Hey, chemo’s working, or the systemic therapy’s working. The only thing that seems to be left is the area in your breast. Then for a conversation with medical oncology, we say you don’t have to come off your medications. This is a good time to remove the breast cancer to control that problem.

There are a lot of new and promising treatments for metastatic breast cancer. So, the treatments in general and the novel treatments and studies really vary based on the subset of metastatic breast cancer. So, when we’re making our treatment decisions, a lot of it is defined by those markers. So, if someone has a tumor that is hormone receptor, estrogen and progesterone receptor positive, and HER2-negative, the mainstay of treatment is typically drugs that target estrogen and often partnering drugs that target estrogen with other more novel or newer treatments.

So, just in the last five plus years, there have been a number of new drugs and even new drug categories that we didn’t have previously. So, for that population of the estrogen receptor positive tumors, the biggest breakthrough over the last number of years has been a class of drugs called CDK4/6 inhibitors. So, that includes drugs like Ibrance, Kisqali, Verzenio. And they’ve emerged as a very important and effective and often a recommendation for our first-line treatment for these patients combined with anti-estrogen therapies that have vastly improved outcomes for patients. So, a much higher percentage of patients respond to these drugs, the duration of the responses has extended quite a bit. And importantly, patients tend to tolerate this drug class really, really well.

 So, for many patients starting out with that diagnosis, this type of drug class is going to be part of the discussion. Even in the last year, another drug category has emerged with approval of a new drug called alpelisib, which is something called at PI3 kinase inhibitor. So, again, back to defining the options based on the molecular profile of the tumor. So, this newer oral drug also partnered with anti-estrogen therapy, has been an important breakthrough for the treatment of patients who harbor this specific molecular abnormality. So, important to define whether that’s an option by some of these molecular testing.

There’s also newer drugs and studies of newer drugs that affect the estrogen receptor in different ways than some of our traditional medications.

And this is an ongoing area of significant research. So, that’s the estrogen receptor positive tumors.

For patients who have HER2-positive tumors, these are tumors that tend to be more aggressive, that tend to require more aggressive upfront treatment, which usually involves drugs that specifically target HER2. So, again, defining what’s driving the tumor and hopefully having drugs available that can target that specific abnormality. So, HER2 targeted drugs have evolved quite a bit over the last couple of decades.

Initially, we just had a drug called Herceptin and then a drug called Perjeta or pertuzumab was developed. Then more recently a drug called Kadcyla. And then even in just the last six to 10 months, two new drugs that target that HER2 protein. One of them is called tucatinib, the other one is called Enhertu. They’re not necessarily appropriate for the first line of treatment, but really sort of expands our toolbox in terms of how we treat these types of tumors. And these are developments that have occurred, for one of the drugs, just in the last six months, and the other within the last year. So, a lot of progress.

And then for the third subset of tumors, which are the triple-negative tumors, those are the ones that do not over-express estrogen, do not have estrogen or progesterone receptors, and don’t overexpressed HER2. This has been historically an area of unmet need. So, tumors where we can’t use anti-estrogen therapies, we can’t use HER2 targeted drugs. And so, the main stay has always been chemotherapy. And even for this subset, we’ve had progress.

So, one of the drug classes that’s been approved in the last couple years for triple-negative breast cancers is immunotherapy. So, immunotherapy has gotten a lot of press. It’s been really breakthrough treatment for a lot of different cancers, has lagged behind to some degree in breast cancer, but has become now one of the early treatment options for people with metastatic disease, specifically those that harbor a molecular marker, an immune marker, something called PD-L1. So, another example of the tumor’s biology dictating potentially one of the treatment options.

There have been other drugs that have been approved for triple-negative breast cancers in women who have BRCA mutation, so who have germline genetic predisposition to breast cancer. And that opens another array of treatment tools that have been approved in the last few years. And then more recently, just over the last six months, another drug that’s been approved for triple-negative breast cancer, which is a drug called sacituzumab, again, not first treatment, but something that defines potentially future lines of treatment. So, big picture, there has been a lot of progress that increasingly alters our treatment tools for patients and allows us to have sequential treatments that can be effective if their given treatment is no longer effective.

So, when we’re determining a treatment approach, there are a number of variables. So, to some degree, based on a patient’s individual characteristics, their age, their other health issues, may guide what treatments are available or indicated or even desirable from a patient’s standpoint. To some degree, the locations and extent of disease are important. So, if someone has cancer and that’s causing a particular symptom, with bony sites being a particular example, there may be a role for something targeted; Something like radiation, and in rare cases, surgery to target a specific symptomatic or worrisome spot of metastatic cancer.

In general, the mainstay of treatment for metastatic breast cancer is what we call systemic treatment or medical treatment, treatment that’s going to go everywhere and treat the cancer wherever it is. In some situations, we may be deciding between more or less aggressive treatment, and the locations and sites of disease may be important in determining that. If someone has extensive disease, for instance in a vital organ like the lung, the liver, the brain, we may start with something more versus less aggressive to try to get it better under control quickly. Whereas people with more limited metastatic disease may be able to start with something less aggressive.

And then beyond that, a lot of the decision-making is based on those molecular markers that I alluded to, which are defined by the hormone receptor status. So, whether the tumor expresses those estrogen and progesterone receptors, and whether the tumor over-expresses HER2. And then to a lesser degree, based on other markers that may be defined by additional tests.

So, every treatment discussion we have is a two-way street. So, our job is to present the data, present options, present recommendations. And often, we have an opinion on where we would fall and if there are a number of different options. But to me, it’s a collaborative discussion. And if there are options, it’s weighing what potential benefit do we get from a single option or from adding something to that particular option versus what are the downsides? And some of it is discussion about logistics. Do we do something IV versus oral? Is there a particular side effect that we’re hoping to avoid, such as hair loss? Which of course, we’re trying to avoid. Some treatments may have a higher likelihood of working, but a higher likelihood of causing hair loss. That may factor into our decision.

So, whether it’s the first decision point when we’re deciding on preliminary therapy or future decision points as we go through this journey, there is always a discussion about this is where we are, these are what our options are. Here’s how we’re going to weigh the pros and cons. And then it comes back to a collaborative decision about how we weigh the risks and rewards and where we’re going with an individual patient.

So, clinical trials are always part of at least the conversation, so they’re always a consideration at each step of our discussion. So, from a preliminary treatment standpoint, we’re always going to go through here are our standard options. Here’s, again, what we think is most appropriate. And if there’s a clinical trial that’s appropriate in that scenario, we’ll lay that out there as an option. So, a clinical trial is always worth discussing. It’s always worth asking that your doctor, “Is a clinical trial appropriate for me at this point?” But it’s not always the right recommendation.

So, there are a lot of scenarios, especially at the beginning of treatment for metastatic disease where we have so many options, and so many new and novel treatment options and drugs that have been approved fairly recently that have defined the standard of care, that the standard is going to be often what we recommend. And a clinical trial may be something that we would use if that treatment fails to work or at some future point down the line. And at other points in time, we have very good, appropriate clinical trials that could be indicated at any step along the way. So, it’s worth the discussion. Whether it’s the recommendation or not depends on the circumstances, it depends on the time. What we have today was very different than what we might’ve had available six months ago and six months from now. But clinical trials are out there, and if the location that a patient is going doesn’t have access to clinical trials, it’s always reasonable to ask too, “Should I be going somewhere else to see if a clinical trial is appropriate?”
