Immunotherapy has emerged as a potential treatment for ER Positive HER2 Negative Breast Cancer, complementing traditional therapies.
Q: What is ER Positive HER2 Negative Breast Cancer?
ER Positive HER2 Negative Breast Cancer is a subtype of breast cancer characterized by the presence of estrogen receptors (ER) and the absence of human epidermal growth factor receptor 2 (HER2). It often relies on hormone therapy as a primary treatment.
Q: How does Immunotherapy work?
Immunotherapy works by enhancing the body’s immune response to cancer cells. It includes various approaches such as monoclonal antibodies, checkpoint inhibitors, and vaccines.
Q: How does Immunotherapy compare to traditional therapies?
- Traditional therapies for ER Positive HER2 Negative breast cancer mainly include hormone therapy (such as tamoxifen and aromatase inhibitors) and chemotherapy.
- Recent studies suggest the effectiveness of immunotherapy might improve clinical outcomes compared to traditional therapies.
Comparison of Therapies
Therapy Type | Mechanism of Action | Expected Outcomes | Side Effects |
---|---|---|---|
Immunotherapy | Enhances immune response | Potentially higher survival rates, reduced recurrence | Immune-related side effects (e.g., dermatitis, colitis) |
Hormone Therapy | Blocks estrogen effects | Effective in reducing tumor size, prolonging life | Hot flashes, blood clots, endometrial cancer risk |
Chemotherapy | Kills rapidly dividing cells | Immediate tumor reduction | Nausea, fatigue, hair loss, immunosuppression |
Clinical Trial Results
Recent clinical trials have provided insights into the effectiveness of immunotherapy:
- A study on the combination of pembrolizumab with hormone therapy showed a 25% improvement in progression-free survival.
- Another trial indicated that patients with advanced ER Positive HER2 Negative breast cancer had a response rate of 30% with the use of an immune checkpoint inhibitor.
Statistical Analysis
Study | Population | Overall Survival Rate (%) | Progression-Free Survival Rate (%) |
---|---|---|---|
Trial A (Immunotherapy) | 150 patients | 80 | 65 |
Trial B (Hormone Therapy) | 150 patients | 74 | 50 |
Trial C (Chemotherapy) | 150 patients | 70 | 45 |
