The combination of tucatinib (Tukysa), trastuzumab (Herceptin), and capecitabine (Xeloda) has shown to be effective in the treatment of HER2-positive breast cancer with leptomeningeal metastases. Previous preclinical data has helped elucidate HER2 brain trophism, the blood-brain/blood-tumor barrier(s), and the brain tumor microenvironment, all of which can lead to development of novel therapeutic options. However, HER2-positive and triple negative breast cancer with the incidence of more than 30% of brain metastases were at high risk group of brain metastases. About 20 percent of all breast cancers are HER2 positive. Redness or a thickening in a breast or nipple. The others include the bones,. However, abnormal levels of these biomarkers may also be a sign of another condition that is not cancer. It is second only to non-small cell lung cancer in causing brain metastasis.

HER2-positive breast cancer. Discomfort in a breast or nipple. Unusual nipple discharge. All breast cells have HER2 proteins, which are receptors that control how the cells grow and divide. Historically, in many solid tumors the average survival after a diagnosis of brain metastases is about 6 months, but that is not the case in women with HER2-positive breast cancer, Lin said. These cancer cells grow and divide faster than healthy cells, causing tumors to form. Despite initial treatment with trastuzumab and a taxane, patients with HER2-positive metastatic breast cancer will often experience disease progression. . •Survival has improved for patients with both early stage-breast cancer and metastatic breast cancer •HER2-positivity is a known risk factor for the development of brain metastases •Up to 50% of patients with HER2-positive metastatic breast cancer develop brain metastases over time •Paucity of guidance for patients in this setting Development of brain metastases can occur in up to 30-50% of patients with breast cancer, representing a significant impact on an individual patient in terms of survival and quality of life.
