Systemic Treatment Options for Breast Cancer – Chemotherapy, Hormonal Therapy, Targeted Therapy, Immunotherapy
Understanding Systemic Treatment for Breast Cancer
When it comes to treating breast cancer, systemic treatment plays a crucial role in targeting cancer cells throughout the body. Systemic treatments are medications that can be given orally or intravenously to treat cancer by reaching cancer cells anywhere in the body. This type of treatment is often used in addition to surgery or radiation therapy to help prevent the cancer from spreading or coming back.
Systemic treatments work by circulating through the bloodstream, allowing them to reach cancer cells that may have spread beyond the primary tumor site. These treatments can be particularly effective in treating breast cancer that has metastasized or recurred after initial treatment.
There are different types of systemic treatments available for breast cancer, each with its own mechanisms of action and potential side effects. It is important for patients to work closely with their healthcare team to determine the most appropriate treatment plan for their specific type and stage of breast cancer.
Systemic treatment options for breast cancer include:
- Chemotherapy: This treatment uses drugs to kill cancer cells or stop them from growing. Chemotherapy is often given in cycles and may be used before or after surgery.
- Hormonal therapy: Hormonal therapies target hormone receptors on cancer cells to block the effects of hormones that can fuel the growth of certain types of breast cancer.
- Targeted therapy: Targeted therapies are designed to target specific molecules or pathways involved in the growth of cancer cells. These treatments can be more precise in targeting cancer cells and may have fewer side effects compared to traditional chemotherapy.
- Immunotherapy: Immunotherapy works by harnessing the body’s immune system to recognize and attack cancer cells. This type of treatment can be particularly beneficial in certain subtypes of breast cancer.
Understanding the different types of systemic treatments available for breast cancer is key to making informed treatment decisions. It is essential for patients to discuss all treatment options with their healthcare providers and inquire about the potential benefits and risks associated with each type of therapy.

Different Types of Systemic Treatments
1. Chemotherapy
Chemotherapy is a common systemic treatment for breast cancer. It involves the use of drugs to kill cancer cells or prevent them from growing and dividing. Chemotherapy can be given in various ways, such as through pills, injections, or intravenous (IV) infusions.
According to the National Cancer Institute, chemotherapy may be used before surgery to shrink tumors (neoadjuvant chemotherapy), after surgery to eradicate any remaining cancer cells (adjuvant chemotherapy), or to treat metastatic breast cancer that has spread to other parts of the body.
Chemotherapy drugs can have side effects, including hair loss, fatigue, nausea, and increased risk of infection. The choice of drugs and treatment schedule will depend on the specific type of breast cancer and individual patient factors.
2. Hormonal Therapy
Hormonal therapy, also known as endocrine therapy, is another type of systemic treatment for breast cancer, particularly for hormone receptor-positive breast cancers. This treatment targets the hormones estrogen and progesterone, which can promote the growth of certain types of breast cancer.
Common hormonal therapy drugs include Tamoxifen, Letrozole, and Anastrozole. These medications work by blocking the effects of estrogen or reducing its production in the body, thereby preventing the cancer cells from receiving the signals they need to grow.
According to a study published in the New England Journal of Medicine, hormonal therapy has been shown to significantly reduce the risk of recurrence in hormone receptor-positive breast cancer patients.
3. Targeted Therapy
Targeted therapy is a type of systemic treatment that targets specific molecules involved in cancer growth and progression. Unlike chemotherapy, which affects all rapidly dividing cells, targeted therapy aims to attack cancer cells while causing less harm to normal cells.
One example of targeted therapy for breast cancer is Trastuzumab (Herceptin), which targets the HER2 protein found in some breast cancers. Another targeted therapy drug is Pertuzumab (Perjeta), which works in combination with Trastuzumab for HER2-positive breast cancer treatment.
Research published in the Journal of Clinical Oncology indicates that targeted therapy can improve outcomes for certain types of breast cancer, leading to better survival rates and reduced recurrence risk.
4. Immunotherapy
Immunotherapy is an innovative approach to cancer treatment that harnesses the power of the immune system to recognize and destroy cancer cells. It works by stimulating the body’s immune response to target and attack cancer cells, potentially offering long-lasting benefits.
One form of immunotherapy for breast cancer is Pembrolizumab (Keytruda), which has shown promising results in clinical trials for patients with advanced triple-negative breast cancer. This medication helps the immune system identify and attack cancer cells more effectively.
According to data from the ClinicalTrials.gov database, ongoing research is exploring the role of immunotherapy in breast cancer treatment and its potential to improve survival outcomes for patients with hard-to-treat forms of the disease.
