Immunotherapy for Breast Cancer Treatment
What is Immunotherapy?
Immunotherapy is a treatment that boosts or modifies the body’s immune system to detect and attack cancer cells. Unlike chemotherapy or radiation, which act directly on cancer cells, immunotherapy enhances natural immune defense
Which Types of Breast Cancer Can Benefit?
A subtype that does not respond to hormonal or HER2-targeted therapy.
Especially in patients with PD-L1 positive tumors.
Drugs Used in Immunotherapy
1. Immune Checkpoint Inhibitors
- e.g., PD-1/PD-L1 inhibitors
- Block immune “brakes” and allow T-cells to attack cancer.
2. Cancer Vaccines (under research)
- Train the immune system to specifically target breast cancer cells.
3. Monoclonal Antibodies
- Help direct immune responses against cancer.
Benefits of Immunotherapy
- Expands treatment options for difficult-to-treat breast cancers
- Improves long-term disease control
- May cause fewer side effects compared to chemotherapy
Possible Side Effects
- Overactive immune response leading to inflammation in organs such as the lungs, intestines, or liver
- Requires close monitoring by oncologists
summarize
Immunotherapy for breast cancer is a groundbreaking approach, especially for TNBC and PD-L1 positive cases. By enhancing immune system function, it provides new hope for better disease control and improved patient survival.
