For women with stage IV breast cancer, systemic drug therapies are the main …
Which breast cancer subtype has the best prognosis?
About 40 percent of breast cancers are luminal A tumors [46-48]. Of the 4 major subtypes, luminal A tumors tend to have the best prognosis (chance of survival), with fairly high survival rates and fairly low recurrence rates [46-51].

Can you go into remission with Stage 4 metastatic breast cancer?
Metastatic breast cancer may never go away completely. But treatment can control its spread. Cancer may even go into remission at some points. This means you have fewer signs and symptoms of cancer.Apr 14, 2021
Which molecular subtypes of breast cancer is most responsive to hormone therapy?
Luminal B cancer cells tend to grow faster than the luminal A type and are considered more aggressive. They are positive for hormone receptors and for a higher-than-normal amount of HER2, so they're both HR-positive and HER2-positive.

These tumors frequently have low histological grade, low degree of nuclear pleomorphism, low mitotic activity and include special histological types (i.e., tubular, invasive cribriform, mucinous and lobular) with good prognosis.
What happens if HER2 is negative?
Cancer cells that are HER2 negative may grow more slowly and are less likely to recur (come back) or spread to other parts of the body than cancer cells that have a large amount of HER2 on their surface. Checking to see if a cancer is HER2 negative may help plan treatment.
Which tumor has the best survival?
Hormone receptor positive tumors (ER+ or PR+) have better overall survival and lower rates of metastasis. Although these studies have shed light on the relationship between breast cancer subtype and metastasis, most studies have been on a relatively small scale.

(The PD-L1 protein is found is about 20% of triple-negative breast cancers.)
What is the best treatment for bone metastases?
Treatment to relieve symptoms depends on where the cancer has spread. For example, pain from bone metastases may be treated with radiation therapy, drugs called bisphosphonates such as pamidronate (Aredia) or zoledronic acid (Zometa), or the drug denosumab (Xgeva).
What hormones are used for cancer?
For hormone receptor-positive (ER-positive or PR-positive) cancers that were being treated with hormone therapy, switching to another type of hormone therapy sometimes helps. For example, if either letrozole (Femara) or anastrozole (Arimidex) were given, using exemestane, possibly with everolimus (Afinitor), may be an option. Another option might be using fulvestrant (Faslodex) or an aromatase inhibitor (such as letrozole), along with a CDK inhibitor. If the cancer has a PIK3CA mutation and has grown while on an aromatase inhibitor, fulvestrant with alpelisib might be considered. If the cancer is no longer responding to any hormone drugs, chemotherapy is usually the next step.
What is the treatment for HER2 negative cancer?
HER2-negative cancers in women with a BRCA gene mutation. These women are typically treated with chemotherapy (and hormone therapy, if the cancer is hormone receptor-positive). An option after getting chemo is treatment with a targeted drug called a PARP inhibitor, such as olaparib or talazoparib.

For many types of cancer, it is also called stage IV (4) cancer. The process by which cancer cells spread to other parts of the body is called metastasis .
How do cancer cells spread?
Cancer cells spread through the body in a series of steps. These steps include: 1 growing into, or invading, nearby normal tissue 2 moving through the walls of nearby lymph nodes or blood vessels 3 traveling through the lymphatic system and bloodstream to other parts of the body 4 stopping in small blood vessels at a distant location, invading the blood vessel walls, and moving into the surrounding tissue 5 growing in this tissue until a tiny tumor forms 6 causing new blood vessels to grow, which creates a blood supply that allows the metastatic tumor to continue growing
Can metastatic cancer cells grow again?
But, as long as conditions are favorable for the cancer cells at every step, some of them are able to form new tumors in other parts of the body. Metastatic cancer cells can also remain inactive at a distant site for many years before they begin to grow again, if at all.
Is metastatic cancer the same as primary cancer?
Metastatic cancer has the same name as the primary cancer. For example, breast cancer that spreads to the lung is called metastatic breast cancer, not lung cancer. It is treated as stage IV breast cancer, not as lung cancer. Sometimes when people are diagnosed with metastatic cancer, doctors cannot tell where it started.
Does metastatic cancer cause pain?
Symptoms of Metastatic Cancer. Metastatic cancer does not always cause symptoms. When symptoms do occur, what they are like and how often you have them will depend on the size and location of the metastatic tumors.
