Abstract:
The triple-negative subtype of breast cancer (TNBC) has the bleakest prognosis, owing to its lack of either hormone receptor as well as human epidermal growth factor receptor 2. Henceforth, immunotherapy has emerged as the front-runner for TNBC treatment, which avoids potentially damaging chemotherapeutics. However, despite its documented association with aggressive side effects and developed resistance, immune checkpoint blockade continues to dominate the TNBC immunotherapy scene. These immune checkpoint blockade drawbacks necessitate the exploration of other immunotherapeutic methods that would expand options for TNBC patients. One such method is the exploitation and recruitment of natural killer cells, which by harnessing the innate rather than adaptive immune system could potentially circumvent the downsides of immune checkpoint blockade. In this review, the authors will elucidate the advantageousness of natural killer cell-based immuno-oncology in TNBC as well as demonstrate the need to more extensively research such therapies in the future.
Insights
Triple-negative breast cancer (TNBC) immunotherapy faces challenges. Natural killer (NK) cell therapies offer a promising alternative to immune checkpoint blockade, potentially improving outcomes for TNBC patients.
Area of Science:
- Oncology
- Immunology
- Cancer Research
Background:
- Triple-negative breast cancer (TNBC) has a poor prognosis due to lacking key receptors.
- Immunotherapy is a preferred treatment, but immune checkpoint blockade has limitations.
- Existing therapies necessitate exploring novel immunotherapeutic strategies for TNBC.
Purpose of the Study:
- To review the benefits of natural killer (NK) cell-based immunotherapy for TNBC.
- To highlight the potential of harnessing the innate immune system for TNBC treatment.
- To emphasize the need for further research into NK cell therapies for TNBC.
Main Methods:
- Literature review of current immunotherapy approaches for TNBC.
- Analysis of the mechanisms and advantages of NK cell-mediated immunity.
- Evaluation of NK cell-based strategies as alternatives to immune checkpoint blockade.
Main Results:
- NK cells offer a potential alternative to current immunotherapies.
- Harnessing innate immunity via NK cells may overcome resistance and side effects.
- NK cell-based immuno-oncology presents a promising avenue for TNBC treatment.
Conclusions:
- NK cell-based therapies warrant further investigation for TNBC.
- Exploiting NK cells could provide new treatment options for TNBC patients.
- Further research is crucial to develop effective NK cell-driven immunotherapies for TNBC.
