(BPT) - We often talk about breast cancer as if it is one disease. “Yeah, she had breast cancer,” or “she had a lump removed.” Even, “she has breast cancer. She’s going through chemo.”
But all breast cancers may not be the same. And chances are good that unless you or someone you are close to has been impacted directly, you may not know that.
Most breast cancers are defined by the presence of certain cancer cell receptors – specifically, hormone receptors called estrogen and progesterone receptors and a protein called human epidermal growth factor 2 (HER2). Knowing which receptors are present helps a doctor choose a treatment that a cancer type is most likely to respond to.
About 10-15% of all breast cancers, however, have little to no presence of any of these three receptors. In fact, they’re so named: “triple-negative” (TNBC), for the absence of all three.
Triple-negative breast cancers tend to spread faster than other breast cancers, and because they don't have the hormone receptors or HER2 protein, there are fewer medicines that work against them. This makes TNBC more aggressive than other invasive breast cancers.
“It’s triple-negative breast cancer” is often a much different diagnosis than “it’s breast cancer.”
Younger Women and People of Color Are Most Likely to Receive a TNBC Diagnosis
TNBC can take an especially hard toll. It affects younger women, before many have even started thinking seriously about mammograms or screenings. It is more likely to be diagnosed in women under 40 than most other types of breast cancer, and it is more common in Black and Hispanic women. To add to this, because it’s aggressive, it can become very serious very quickly. Once it spreads, only about 12% of women with metastatic disease survive 5 years.
Treatment Options For TNBC Are Expanding
For women who are facing an advanced TNBC diagnosis, it’s important to talk to the doctor about treatment options. Most patients with advanced or metastatic disease (TNBC that has spread) will receive chemotherapy, but many will progress at some point – even if the chemotherapy works initially. Until recently, there have been no other options after chemotherapy stops working. That is changing.
Trodelvy® (sacituzumab govitecan-hziy) is a different kind of medicine, called an antibody-drug conjugate (ADC), that is approved for adults with second-line and later metastatic TNBC (after two or more prior treatments, including one for metastatic disease). Trodelvy is indicated for TNBC (negative for estrogen and progesterone hormone receptors and HER2) that has spread to other parts of the body (metastatic) or cannot be removed by surgery, and who have received two or more prior treatments, including at least one treatment for metastatic disease. That means when chemotherapy stops working, people with metastatic TNBC have another option.
