HER2-enriched disease are more immunogenic than others e. Luminal A or B. However, as more HER2-targeted agents become available, a better understanding of the role played by the immune system in modulating therapy response to different agents will be needed.

Breast cancer is the second most common cause of death for women behind lung cancer and the most common cause of cancer deaths for women aged 45—55 years old CDC. Although there continue to be enormously large numbers of disease incidence, deaths have been declining due to the disease with two hallmark time frames. These remarkable accomplishments in developing novel targeted therapies for breast cancer, along with a better understanding of the disease biology have improved disease outcome over the past 20 years.

In his lecture, Dr. Traztuzumab and other HER2-targeted therapies that have followed pertuzumab, TDM-1, lapatinib, afatinib and neratinib helped to transform a disease with poor prognosis into a treatable and survivable type of breast cancer. Despite the remarkable improvement traztuzumab offered in HER2-positive breast cancer, many of these tumors were resistant to the therapy, leading to clinical trials testing combinations of HER2-targeted therapies with chemotherapies in both the pre-surgery neoadjuvant and post-surgery adjuvant settings.

Ductal carcinoma in situ DCIS is a highly heterogeneous disease. It presents in a variety of ways and may or may not progress to invasive cancer, which poses challenges for both diagnosis and treatment. Speakers and attendees were encouraged to explore opportunities for future collaboration and research to improve our understanding and clinical management of this disease.

Cancer immunotherapy has evolved dramatically with improved understanding of immune microenvironment and immunosurveillance. The immunogenicity of breast cancer is rather heterogeneous. Specific subtypes of breast cancer such as estrogen receptor ER -negative, human EGF receptor 2 HER2 -positive, and triple-negative breast cancer TNBC have shown evidence of immunogenicity based on tumor—immune interactions.

The deregulation of cell growth in milk-producing glands, milk-carrying tubes, or connective tissues is known as breast cancer. It originates from genetic mutations and has the ability to metastasize. Primary tumor cells repetitively divide and lead to inappropriate mechanisms, tumorigenesis, and carcinogenesis, characterized by improper cell type, function, lifetime, and self-destruction.

There are perhaps a dozen high-penetrance and moderate-penetrance breast cancer genes identified to date, which together account for about ten percent of all breast cancer cases [ 1 ]. The risk of cancer differs by gene and also may differ for …. There is accumulating evidence that tumor-infiltrating lymphocytes TILs have both prognostic and predictive values in breast cancer BC [ 12 ], especially for triple-negative TN BC [ 3 — 5 ].

When NCI-supported researchers discovered that the HER2 gene is important for breast cancer growth, this led to the development of the drug trastuzumab and other targeted treatments that have improved survival for women with HER2-positive breast cancer. For years, doctors and researchers have noted that not all cancers are alike. But for other patients, their tumors grow rapidly and spread like wildfire. In the early s, after the discovery that a mutated gene called HER2 could stimulate excessive cell growth and division, many scientists wondered if certain genes might make cancers grow and spread rapidly.
