Becoming an Empowered and [ACT]IVATED Breast Cancer Patient

/in , , , , , , , /by

Patient Empowerment Network (PEN) is committed to helping educate and empower patients and care partners in the breast cancer community. Breast cancer treatment options are ever-growing with research advancements in treatments and testing, and it’s important for patients and families to educate themselves with health literacy tools and resources on the latest information in breast cancer care. With this goal in mind, PEN kicked off the [ACT]IVATED Breast Cancer program, which aims to inform, empower, and engage patients to stay abreast of up-to-date information in breast cancer care. 

The [ACT]IVATED Breast Cancer program is aimed at newly diagnosed breast cancer patients, yet it is beneficial at any stage of disease. [ACT]IVATED Breast Cancer helps patients and care partners stay in the know about the latest options for their breast cancer, provides patient activation tools to help overcome barriers to accessing care, and powerful tips for self-advocacy, coping, and living well with cancer.

Breast Cancer Disparities

With more focus on disparities in breast cancer outcomes, research studies are starting to reveal actionable information on genetic differences. A recent study uncovered a racial disparity among cancer types that are hormone receptor-negative but HER2-positive. While treatment has been successful in white patient groups, the outcomes have been less successful in Black patient groups. The study also noted key gene mutations in the MAPK pathway occur more frequently in Black patients, which warrants further investigation.

Lisa Hatfield and Dr. Demetria Smith-Graziani

Breast cancer expert Dr. Demetria Smith-Graziani from Emory University School of Medicine shared updates about her breast cancer research. “…what we found is that regardless of the type surgery Black women were reporting more severe pain compared to white women, and so that’s what prompted me to engage in my most recent research project…the reason that I’m looking at those specific set of factors is because there are a number of psychological components to the way that we feel pain, such as anxiety, depression and yes trust that are linked to the way that we experience pain and how severe that pain is and how much that pain affects our lives.

Proactive Steps to Improve Breast Cancer Care

Knowledge gained from research studies can be utilized by patient advocates, and actions can be taken to improve breast cancer care and in the evolution of research efforts for all patients. Dr. Smith-Graziani discussed the importance of clinical trials in driving advancements in breast cancer research and treatments. “…all of the current treatments we have that are FDA-approved were approved because of the results from clinical trials that previous patients participated in…And we won’t get any new advancements in breast cancer treatments and come up with even better, more effective treatments, unless we are able to do more clinical trials with more patients. The other part is that in the past, most of the participants of clinical trials have been pretty much the same, they have been mostly white, mostly have insurance, mostly of a higher socioeconomic status, and those patterns continue today, we are still trying to get the patients in clinical trials to reflect the true population of the United States. And in order to know that clinical trials are effective for everybody, we need to have everybody in those trials.”

Dr. Demetria Smith-Graziani

Dr. Smith-Graziani also explained breast cancer subtypes and why it’s vital for patients to learn about their breast cancer subtype. “When we are looking at the cancer cells under the microscope, we look at specific proteins in these cells, and based on what proteins we see, we designate it as positive or negative for the estrogen receptor, the progesterone receptor, or a protein called HER2. When a cancer expresses the estrogen or progesterone receptor, that means that it feeds off of those hormones that your body makes, and that’s why we refer to it as hormone receptor-positive…And it’s important that we know what subtype of breast cancer you have, because it affects the type of treatment that you can get.”

Learning about family history of cancer is also another key to staying proactive in breast cancer care. Dr. Smith-Graziani explained, “So breast cancer definitely can be hereditary, we are aware of some forms of inherited breast cancers, and we have identified certain mutations in genes that are passed down along family lines, that increase the risk of getting breast cancer…ask your family members about their cancer history so that you’re aware of it, and then ask your oncologist if they recommend genetic counseling or testing.”

Another fundamental step in proactive breast cancer care is for patients to ask about their treatment plan. Dr. Smith-Graziani shared advice for patients. “…in addition to potential side effects are how long is my treatment meaning how long am I going to have to stay in the infusion center if I’m getting an IV medication? Or how many months of treatment do I need to get? And then how much time do I need to take off of work? Am I going to be able to work while getting my treatment, so it’s those little things which aren’t so little that are important to discuss, so that the patients can get the best overall picture about how each treatment will affect them in the short and the long term.”

Dr. Smith-Graziani stressed the value of getting your questions answered and also the value of additional expert opinions. “I think it’s important for patients to be as informed as possible to make sure that they are getting all of their questions answered by their doctor, and if you don’t feel like your questions are getting answered, if you don’t feel like your concerns are being appropriately addressed or acknowledged, please make sure that you get a second or a third opinion and talk to another doctor to see if they can answer your questions.”

Lisa Hatfield:

Dr. Smith, can you explain the difference between HR-positive and HER2-negative metastatic breast cancer? And what promising treatments are available for those types of cancer?

Dr. Demetria Smith-Graziani:

So when we look at the cancer cells under the microscope, we test for different proteins, and one of those proteins is called HER2. Breast cancers that overexpress the HER2 protein are considered to be HER2-positive, and those do not have this overexpression are considered to be HER2-negative.  

For metastatic or stage IV breast cancer, cancers that are HER2-positive, have the option of being treated with HER2-targeted therapy, and that means that we have certain drugs that will seek out the cancer cells that are expressing these HER2 proteins bind to those cells and deliver treatments to those cancer cells that destroy those cancer cells in a more targeted fashion than traditional chemotherapy that tends to destroy all rapidly dividing cells equally.

So my activation tip for patients is ask about the HER2 status of your breast cancer and ask about what the available standard treatments are for HER2-positive metastatic breast cancer, as well as potential clinical trial options.

What are the various subtypes of breast cancer?

Dr. Demetria Smith-Graziani:

So we tend to think of breast cancer as being either hormone receptor-positive and HER2-negative, or hormone receptor-positive and HER2-positive or hormone receptor-negative and HER2-positive, or what we call triple-negative. Now, that’s really confusing. So let me take a step back. When we are looking at the cancer cells under the microscope, we look at specific proteins in these cells, and based on what proteins we see, we designate it as positive or negative for the estrogen receptor, the progesterone receptor, or a protein called HER2. When a cancer expresses the estrogen or progesterone receptor, that means that it feeds off of those hormones that your body makes, and that’s why we refer to it as hormone receptor-positive.

When your breast cancer over expresses a particular protein called HER2 that allows us to target your cancer with certain treatments that target HER2-positive cells. When a breast cancer is triple-negative, that means that it is negative for all three of those proteins, it does not have the estrogen receptor, the progesterone receptor, or the HER2 protein. 

And it’s important that we know what subtype of breast cancer you have, because it affects the type of treatment that you can get. So my activation tip is that patients should ask, “What subtype of breast cancer do I have, and what kinds of treatment would I expect with the subtype of breast cancer?”

Factors That Guide a Metastatic Breast Cancer Treatment Decision

 

Transcript:

Dr. Kruse:                   

At this year’s San Antonio Breast Cancer Symposium, there were a few interesting presentations about the treatment of first-line metastatic triple-negative breast cancer that I think patients should be aware of.

Two of the presentations centered around trials that were presented in the past. Those reporting, patients reported outcomes from the IMpassion 130 study, which looked at chemotherapy for metastatic triple-negative disease plus the immunotherapy atezolizumab. And then, there was also an update on the results from the KEYNOTE-355 study, which was a study again of chemotherapy for metastatic triple-negative patients in combination with pembrolizumab, a different immunotherapy. And both of these studies showed that there was benefit for women in certain sub-groups of triple-negative breast cancer when looking at addition of immunotherapy.

And so, what I’d like to draw patients’ attention to with these presentations is that you have to be aware of if you fall into one of these categories so you know if you’re a candidate for the particular type of immunotherapy that can be added to chemotherapy. There are two different ways to test for if a patient is a candidate for immunotherapy and they are both tests that can be done on biopsies of metastatic or cancer recurrent sites in the body.

They can also be sent off of original breast cancer tumors. And what we now know is that for patients who do not have markers that suggest immune activation or where the immune system would be responsive to immunotherapy the addition of that extra therapy really does not help to improve cancer control over chemotherapy alone. And I think that’s a really important topic because everyone is very interested in immunotherapy, but it does have side effects of its own and it can actually be lasting side effects in terms of inflammation in organs like the liver, the colon, and the lungs.

And then, the third presentation that I’d like to bring up is the IPATunity study, which looked at the addition of a targeted therapy called ipatasertib to, again, chemotherapy for the first treatment of metastatic triple-negative disease.

And so, this is getting into an area of targeted therapy for metastatic triple-negative disease. And again, only looks at patients that have a particular marker that suggests sensitivity to this drug. And those are certain genetic markers, predominately changes in a DNA marker called PIK3CA. In this study, we actually found that there was no benefit for the targeted therapy added to chemotherapy for patients that had that genetic mutation, which was different than what was seen in earlier studies of the same combination. So, I think there’s more work to be done and it’s probably too early to say that this targeted therapy will not be used in treatment of metastatic breast cancer.

But what all of these research studies show together is that metastatic triple-negative cancer is not really just one disease. It’s very clear that within that one name, there are multiple different patient types and tumor types that need to be cared for differently.

And so, again, I think the theme from these abstracts and these research presentations is that we have to look into the right therapy for the right patient at the right time, which largely involved DNA-based testing.

So, when patients are thinking about their treatment options and how to best help with their providers about what treatment options exist for them, I think it’s important to recognize the type of testing that may be advantageous in your cancer type.

And so, for all metastatic breast cancer patients, we really recommend that they’ve had genetic testing to look for DNA changes like BRCA mutations that will lead to treatment options. For metastatic triple-negative disease, it’s important to make sure that you’re providers are testing for PDL1, which would make you a candidate for immunotherapy. And then, the more we learn about clinical trials, the more we have options for patients that have had drug-based DNA or genome-based testing. So, that’s an important term for patients to become familiar with is genomic testing.

And I think when you bring that up with your providers, they’ll know what you’re talking about and they’ll know that what you’re potentially interested in is new targeted therapy for the cancer that may either come in combination with chemotherapy or as a standalone treatment option. If you don’t have those options that are available, and FDA approved basis for regular routine patient care, there is always the option of clinical trials.

And so, if that is something that you’re interested in, genomic testing will often open the way. So, I think as you’re writing notes when you’re talking to your providers, you might wanna jot down whether or not you’ve had genetic testing and whether or not you’ve had genomic testing in the past, as both of those things will help potentially address all of your treatment options.

I’ve very hopeful about the research that is going to lead to new developments for breast cancer treatment in the next few years.

I think what we’ve seen both at this San Antonio Breast Cancer Symposium as well as other conferences in the recent past has been a lot of focus on finding the right treatment for the right patient at the right time. And so, patients seem to be very interested in finding out this information. They often come to clinic armed with the most recent data, which allows their providers to have really informed discussions about what the best treatment might be. And to talk about if the new treatments are not great right now, what treatments might look like in the future.

I think the other thing that’s encouraging about the research that we’ve seen presented at this conference is that some of these trials are very, very large. For example, the RxPONDER trial was a trial of over 9,000 patients. And I really think that’s amazing to get that many patients interested in research that may not directly impact their patient care but will impact the care of others moving forward.

It’s just a sign that our breast cancer patients are empowered, and they want to make a difference in the scientific community as a whole.

Dr. Kruse:                   

The San Antonio Breast Cancer Symposium is a national meeting with international presence that combines all of the latest data from research on breast cancer topics. It involves clinical research, basic science research, a lot of patient, and patient advocate support.

And the idea here is to bring together all the different disciplines that are involved in breast cancer patient care and do the best information and knowledge sharing that we can each year.

This year’s San Antonio Breast Cancer Symposium brought us a lot of interesting research focusing on early-stage breast cancer patients. I think the most important presentations that were given had to do with the treatment of high-risk lymph node-positive hormone receptor-positive breast cancer patients. And these were really across three abstracts. The first abstract of interest was the Monarch E study, which looked at high-risk women with hormone receptor-positive HER2-negative breast cancer and optimizing their medical therapy.

So, these patients are typically treated with anti-estrogen therapy and the idea of the research that was presented was if the addition of a targeted medication called abemaciclib or Verzenio could help to improve outcomes for women in this population. And what the trial found was that for women who took their anti-estrogen therapy for the usual length of time but added the abemaciclib for the first two years of that anti-estrogen therapy that there is actually an improvement in cancer-free survival time or an improvement in cure rates. And this was important because these women may not benefit from chemotherapy, as we’ll talk about in another abstract.

An addition research presentation that was given that goes alongside of the monarch E study was that of the Penelope B study. And the Penelope B took a similar population to what was studied in Monarch E. So, again high-risk women with lymph node-positive, hormone receptor-positive, HER2-negative breast cancer; however, in Penelope B, all of these patients had received pre-surgery chemotherapy.

And in order to qualify for the trial, the patients had to have some cancer that remained in the breast or the lymph nodes that was taken out at the time of their surgery. So, these are patients clearly in which chemotherapy did not do the whole job in terms of getting rid of the cancer. And again, the idea here was to add a second targeted therapy to the endocrine therapy to see if that would improve cancer-free time for patients in this population. The difference in this study was that the partner targeted therapy that was used was a drug called palbociclib or Ibrance.

And the drug was actually only used for one year in combination with endocrine therapy rather than two years as was used in the Monarch E study with abemaciclib. Interestingly enough, the Penelope B study was a negative study, meaning that it did not improve the cancer-free survival time for women who took the endocrine therapy plus targeted therapy compared to women who took the endocrine therapy alone.

So, I think that these are two interesting studies that one should look at together. And clearly, may impact what we do for the treatment of high-risk hormone receptor-positive women moving forward. The third abstract that I’d like to touch on that I think was important for women with early-stage breast cancer is the RxPONDER study, also known as SWOG 1007. And this study again was looking at lymph node-positive, hormone receptor-positive HER2-negative breast cancer patients and seeing if the addition of chemotherapy helped to improve their cancer-free survival compared to anti-estrogen therapy alone.

And so, in this study, while the study population was all women with early-stage breast cancer, meeting the one to three lymph node-positive criteria, you really have to break the results down into the results for pre-menopausal women and the results for post-menopausal women.

Because overall the study really showed no significant benefit to chemotherapy on top of endocrine therapy for women in this population; however, we did see that there was a clear benefit for women who were pre-menopausal. So, the women who had no benefit from chemotherapy were largely those who were post-menopausal, while those who were pre-menopausal derived extra benefit from chemo on top of anti-estrogen therapy. And that benefit depended on what the Oncotype recurrent score was.

With women that had the lowest of the recurrent scores having a chemo benefit of about three percent going up to over five percent for women who had Oncotype recurrent scores in the mid-teens to 25 range. In both of these groups, women who had Oncotype scores of 26 or above would have chemotherapy as per our standard of care.

So, I think that this abstract is important because in the past women who had lymph node-positive breast cancer generally received chemotherapy no matter what. More recently we’ve understood that not all of these cancers are created equal and that some cancers may not actually have benefit from chemotherapy in terms of improving cure rate. So, this study is a big step forward to help individualize and specify the treatment for women with lymph node-positive, hormone receptor-positive, HER2-negative early breast cancer.

I’ve very hopeful about the research that is going to lead to new developments for breast cancer treatment in the next few years.

I think what we’ve seen both at this San Antonio Breast Cancer Symposium as well as other conferences in the recent past has been a lot of focus on finding the right treatment for the right patient at the right time. And so, patients seem to be very interested in finding out this information. They often come to clinic armed with the most recent data, which allows their providers to have really informed discussions about what the best treatment might be. And to talk about if the new treatments are not great right now, what treatments might look like in the future.

I think the other thing that’s encouraging about the research that we’ve seen presented at this conference is that some of these trials are very, very large. For example, the RxPONDER trial was a trial of over 9,000 patients. And I really think that’s amazing to get that many patients interested in research that may not directly impact their patient care but will impact the care of others moving forward.

What Could Metastatic Breast Cancer Genetic Testing Advances Mean for You?

 

Transcript:

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.

Katherine:                  

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.
