Although triple-negative breast cancer is challenging to treat, some hope
may be on the horizon thanks to a cancer-killing virus called TVEC
(talimogene laherparepvec).
In a phase 2 clinical trial, 45.9% of patients who received TVEC injections
directly to the tumor during chemotherapy had no signs of cancer after
surgery.
The next step is to conduct a phase 3 clinical trial to confirm the
efficacy of TVEC for triple-negative breast cancer in a larger study
population.
Triple-negative breast cancer, which accounts for 15%Trusted Source of
newly diagnosed breast cancer cases, is characterized by tumors that lack
estrogen receptors, progesterone receptors, and human epidermal growth
factor receptor 2 (HER2) receptors.Currently, the preferred treatment approach for triple-negative breast
cancer is neoadjuvant chemotherapy, a type of chemotherapy administered
before the main treatment for cancer, such as surgery or radiation therapy.Doctors administer it to shrink the size of a tumor, making it easier to
remove that tumor with surgery, or to make radiation therapy more effective.
