Abstract:
Breast cancer is the second leading cause of death for women worldwide. While monotherapy (single agent) treatments have been used for many years, they are not always effective, and many patients relapse after initial treatment. Moreover, in some patients the response to therapy becomes weaker, or resistance to monotherapy develops over time. This is especially problematic for metastatic breast cancer or triple-negative breast cancer. Recently, combination therapies (in which two or more drugs are used to target two or more pathways) have emerged as promising new treatment options. Combination therapies are often more effective than monotherapies and demonstrate lower levels of toxicity during long-term treatment. In this review, we provide a comprehensive overview of current combination therapies, including molecular-targeted therapy, hormone therapy, immunotherapy, and chemotherapy. We also describe the molecular basis of breast cancer and the various treatment options for different breast cancer subtypes. While combination therapies are promising, we also discuss some of the challenges. Despite these challenges, the use of innovative combination therapy holds great promise compared with traditional monotherapies. In addition, the use of multidisciplinary technologies (such as nanotechnology and computer technology) has the potential to optimize combination therapies even further.
Insights
Combination therapies offer a promising approach to treating breast cancer, outperforming single-agent treatments and reducing toxicity. This review explores current combination strategies and future directions for improved patient outcomes.
Area of Science:
- Oncology
- Pharmacology
- Biotechnology
Background:
- Breast cancer remains a leading cause of death in women globally.
- Monotherapy treatments often lead to relapse and drug resistance, particularly in metastatic or triple-negative breast cancer.
- Developing more effective breast cancer treatments is a critical unmet need.
Purpose of the Study:
- To provide a comprehensive review of current combination therapies for breast cancer.
- To discuss the molecular basis of breast cancer and subtype-specific treatments.
- To explore the potential of multidisciplinary technologies in optimizing combination therapies.
Main Methods:
- Review of current literature on breast cancer combination therapies.
- Analysis of molecular mechanisms underlying breast cancer.
- Examination of various treatment modalities including molecular-targeted therapy, hormone therapy, immunotherapy, and chemotherapy.
Main Results:
- Combination therapies show greater efficacy and lower toxicity compared to monotherapies.
- Different breast cancer subtypes may benefit from distinct combination strategies.
- Multidisciplinary technologies like nanotechnology can enhance combination therapy effectiveness.
Conclusions:
- Combination therapies represent a significant advancement over traditional monotherapies for breast cancer.
- Addressing challenges in combination therapy is crucial for clinical success.
- Innovative approaches, including technological integration, hold great promise for improving breast cancer treatment outcomes.
