What cancers can be HER2 positive?

What is the survival rate of HER2 positive cancer?

The outlook for this type of cancer depends on things like the treatment you get and the stage of your cancer. But new treatments like chemotherapy plus trastuzumab have boosted early-stage HER2 positive breast cancer survival rates: 7-year disease-free: Around 93% 10-year disease-free: About 70%-75%

Is it good to be HER2-positive or negative?

It’s healthy in normal amounts, but too much may be a sign of a certain type of breast cancer. Most people with breast cancer have a normal amount of this protein, which means you are HER2-negative. But about 1 in 5 cases are HER2-positive, which means your levels are unusually high.

Which cancer has a correlation with poorer outcomes when HER2 is overexpressed?

HER2 overexpression is directly correlated with poorer outcome in gastric cancer. In a study of 260 gastric cancers, HER2 overexpression was an independent negative prognostic factor and HER2 staining intensity was correlated with tumor size, serosal invasion, and lymph node metastases [33].

Is chemo necessary for HER2-positive?

Trastuzumab and chemotherapy are even recommended for women with very small, HER2-positive breast cancers. Tumors as small as 0.5 cm often warrant such treatment.

What triggers HER2?

In about 25 percent of breast cancers, the cancer cells have an excess of the HER2 protein. This is caused by a mutation in the HER2 (human epidermal growth factor receptor 2) gene. When the HER2 gene mutates, it causes cells in the breast to grow and divide at an uncontrolled rate, leading to tumor growth.

Is HER2-positive breast cancer a death sentence?

“HER2-positive metastatic breast cancer is currently considered an incurable disease, with the majority of patients ultimately relapsing within five years.

What is the most aggressive type of breast cancer?

Metastatic Breast Cancer

The most serious and dangerous breast cancers – wherever they arise or whatever their type – are metastatic cancers. Metastasis means that the cancer has spread from the place where it started into other tissues distant from the original tumor site.

Can HER2-positive cancer be cured?

HER2-positive breast cancer is highly curable because of the availability of these HER2-targeted therapies, so we treat patients fairly aggressively upfront to reduce the risk of them experiencing a stage IV recurrence.

How long is chemo for HER2-positive?

Cycles can last anywhere from about two to four weeks, depending on the combination of drugs. Chemotherapy generally lasts about three to six months. The total length of chemotherapy treatment may vary depending on the stage of breast cancer and a number of other factors.

What does HER2-positive mean?

HER2-positive breast cancer is a breast cancer that tests positive for a protein called human epidermal growth factor receptor 2 (HER2). This protein promotes the growth of cancer cells. In about 1 of every 5 breast cancers, the cancer cells have extra copies of the gene that makes the HER2 protein.

Does HER2-positive run in families?

HER2-positive breast cancer is not hereditary, but some other types of gene mutations related to breast cancer are inherited. Genetic testing can tell you if you have any of the mutations currently known to increase risk for breast cancer or other cancers.
