Five Thousand (5,000)+ years after the
discovery of breast cancer, triple negative breast cancer (TNBC) was officially
recognized as a distinct type of breast cancer in 2006.
That was just 11 years before my diagnosis.
That discovery was quickly followed by a
massive amount of research funds for TNBC. The Komen Foundation, for example,
invested more than $74
million in over 100 research grants focused on triple negative breast cancer. The
Triple Negative Breast Cancer Foundation teamed up with the Komen Foundation in
2009, pledging a total of $6.4 million over five years to fund research to
support the discovery of new TNBC treatments. That may sound like A LOT of
money and for sure, it is.
Overall, breast
cancer is one of the best research-funded diseases in this country. According
to Cancer Health (www.cancerhealth.com),
breast cancer research received over $460 million for research. That figure is
twice as high as the next highest-research-funded cancer, leukemia at $201
million. I fully am aware that I have benefited from such research funding over
the years. The past 20 years uncovered so much about breast cancer. Those discoveries
are a direct effect of funding for research and clinical trials. I wanted to
very much further that work and my participation in the TNBC clinical trial
serves this purpose for me.
And the discovery
of TNBC, the focus on the disease, the funds for research and trials, and the
success of the research all seem to be paying off!
In 2011 – just 5
years after the discovery of TNBC - six different subtypes of TNBC were identified
by a project, led by Komen Scholar Dr. Jennifer Pietenpol and funded by Komen
and the Milburn Foundation. As of 2017, several clinical
trials are now underway that will test new, targeted treatments for the TNBC
subtypes.

Just FYI, I do
not know my TNBC subtype. I was diagnosed on the crisp of the discovery of the TNBC
subtypes and regular testing for the biomarkers was not available. I fell under
– as still most TNBC’ers do – with the tried and true but brutal, chemotherapy treatment
of an anthracycline such as Adriamycin – one of
if not the most powerful chemo drug invented, affectionately known as the “red
devil” (its red in color) - and Cyclophosphamide
(the twins otherwise known as “A/C”), followed
by a Taxane, such as Taxol or Taxotere. Eleven years after the discovery of
TNBC, I was fortunate to be on the cutting edge – following a successful clinical
trial - of introducing to the “chemo party” a fourth chemotherapy drug, Capecitabine,
also known as Xeloda. Xeloda is now part
of the standard of care for TNBC patients with residue tumor post A/C, T.
Clearly, the pace of research, thus knowledge about
the biological terms of TNBC, has picked up in just the last few years. But
back to my original topic of this – now VERY long blog series: WHO tends to be diagnosed
with TNBC? And WHY is that? AND how does
that relate to me?
So, it’s back to “Dr.
Google”. From another trusted site, Triple Negative Breast Cancer Foundation (tnbcFoundation.org), “several studies suggest that being
premenopausal or of African ancestry increases your risk of developing
basal-like or triple-negative breast cancer. Among African American women who
develop breast cancer, there is an estimated 20 to 40 percent chance of
the breast cancer being triple-negative. Researchers do not yet understand why
premenopausal women and women in some ethnic groups have higher rates of
triple-negative breast cancer than other groups of women.”
Let that sink in
a bit. Of all the Black and Brown women diagnosed with breast cancer, up to 40%
of them have TNBC.
Previous studies
have reported that Black women in the US are twice as likely as white women to
be diagnosed with TNBC. However, a 2019 ground-breaking study from the American
Cancer Society (ACS) suggests that saying that all Black women have a
higher risk of being diagnosed with TNBC may be too general of a statement. According
to ACS, “the study reported the prevalence of TNBC in Black women varies
significantly depending on where the women were born. More specifically, Black
women born in the US and Western Africa were diagnosed more often with TNBC than
women born in East Africa.”
The study
continues, “compared with the prevalence of TNBC among Black women born in the
US, Black women born in West Africa had similar rates to Black women born in
the US; the Caribbean had a 13% lower prevalence; and those born in East Africa
had a 47% lower prevalence rate.”
ACS continues, “Unfortunately,
there wasn’t enough data to analyze the prevalence rates of Black women born in
North, Central, or South Africa. The main limitation of the study was missing
information about birthplace. The researchers say it’s important to take
birthplace into consideration when studying different types of breast cancer in
women of African descent in the US and other parts of the world. This could
help cancer experts better understand the diversity of breast cancer among Black
women. The authors say their study “calls for a concerted effort for more
complete collection of birthplace information in cancer registries.””
So, I don’t know. Was the slowness surrounding the discovery and subsequent
push for research of TNBC because the disease affected a smaller % of breast
cancer patients on the whole than other types of breast cancer? Recall the
power grid analogy, if you will. Was it because
a drug, Taxoifen, was already used in women for birth control and thus was an “easy”
treatment win for some types of breast cancer but not for TNBC? IN other words,
had that drug-relationship in women not already been made, would it have taken longer
for the first breast cancer treatments to arrive? Did the pace of research and
knowledge of TNBC have anything at all to do with WHO was more commonly affected
with TNBC?
Maybe a
combination of all factors. Maybe.
What I do know is,
widely speaking, Black people die from disease in far larger numbers than white
people who have the same disease. And so,
the remainder of this post will be about the education of these facts. To
better myself, my anti-racist self, I will use my voice to speak truth on this.
I hope you will continue to read on and join me on this journey.
According to WebMD.com,
“Blacks are 3 times more likely to die of asthma than whites; Black Americans
are 3 times more likely to suffer sarcoidosis than white Americans; Black
American children are 3 times as likely as white American children to have sleep
apnea; Black American men are 50% more likely to get lung cancer than white
American men; and for goodness-sake: Black Americans are half as likely to get flu
and pneumonia vaccinations as white Americans.”

Dr. Clyde
W. Yancy, MD, associate dean of clinical affairs and medical director for heart
failure/transplantation at the University of Texas Southwestern Medical Center,
tells WebMD, “all humans have the same physiology, are vulnerable to the same
illnesses, and respond to the same medicines. Naturally, diseases and responses
to treatment do vary from person to person. But, he says, there are unique
issues that affect Black Americans. Genes
definitely play a role. So does the environment in which people live,
socioeconomic status -- and, yes, racism.”
Dr Yancy continues, “We must recognize there
are some arbitrary issues that are present in the way we practice medicine and
dole out health care. It forces us to think very carefully about the very
volatile issue of race and what race means. At the end of the day, all of us
acknowledge that race is a very poor physiological construct. Race is a
placeholder for something else. That something is less likely to be genetic. It
is more likely to have to do with socioeconomics and political issues of bias
as well as physiologic and genetic issues that go into that same bucket. Some
racial differences are more nuances. But there are issues of disparity and
there are issues relative to racism that operate in a very broad context."
What I can do is
use my voice, my blog, to talk about the diagnosis and outcome disparities between
white women with TNBC and Black women with TNBC. Because they are stark. Even
though as Dr. Yancy says, “all humans have the same
physiology, are vulnerable to the same illnesses, and respond to the same
medicines”. Outside factors such as systematic racial inequalities to access and/or affordable preventative and general health care should be considered. And certainly the lack of medical research focusing on why these disparities exist and how to resolve them needs to be highlighted.
Just as the discovery
of TNBC in 2006 spearheaded a massive amount of funding and knowledge about
TNBC, so may the knowledge, acceptance, and actions to reverse the health effects
of racial inequalities in this country provide an avenue and an opportunity to
close the diagnosis and survival gaps. Everyone - everyone - living with Cancer has HOPE for a cure,
HOPE for the speed and success of medical research, HOPE to live a long life.
It seems I have
more in common with Black and Brown women after all. Perhaps we
ALL do.
