Abstract:
Triple negative breast cancers, which are defined by lack of expression of estrogen, progesterone, or HER2 receptors, represent approximately 15% of all breast cancers, although they account for a much higher proportional of breast cancer mortality. This is due both to their innate aggressive biological characteristics, but also to lack of effective therapies. Conventional chemotherapy is currently the only treatment option, thus there is a critical need to find new and effective targeted therapies in this disease. While investigation of agents such as poly (ADP-ribose) polymerase (PARP) inhibitors and EGFR inhibitors continues, results from recent clinical trials indicate that these therapies are not as active in sporadic triple negative breast cancers as initially hoped. It is important therefore to consider other emerging therapeutic agents. Mutation in p53 is found in the vast majority of triple negative breast cancers, and as such is a target of particular interest. Within this review, several agents with potential activity against aberrant p53 signaling have been considered, as a novel approach to finding an effective targeted therapy for this aggressive breast cancer subtype.
Insights
Triple negative breast cancer (TNBC) is aggressive and lacks effective therapies. This review explores novel treatments targeting p53 mutations, offering hope for this challenging breast cancer subtype.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Triple negative breast cancer (TNBC) accounts for 15% of breast cancers but a higher proportion of mortality.
- TNBC is characterized by the absence of estrogen, progesterone, and HER2 receptors, leading to aggressive biology and limited treatment options.
- Current treatments like conventional chemotherapy are insufficient, and emerging therapies like PARP and EGFR inhibitors show limited efficacy in sporadic TNBC.
Purpose of the Study:
- To review novel therapeutic agents targeting aberrant p53 signaling in triple negative breast cancer.
- To identify potential targeted therapies for TNBC by focusing on p53 mutations, which are prevalent in this subtype.
Main Methods:
- Literature review of emerging therapeutic agents.
- Analysis of agents with potential activity against aberrant p53 signaling.
- Focus on novel approaches for TNBC treatment.
Main Results:
- p53 mutations are found in the majority of triple negative breast cancers, making it a key target.
- Several agents show potential activity against aberrant p53 signaling.
- Emerging therapeutic strategies are being explored beyond conventional chemotherapy.
Conclusions:
- Targeting p53 signaling represents a promising novel approach for treating triple negative breast cancer.
- There is a critical need for effective targeted therapies for TNBC due to its aggressive nature and poor outcomes.
- Further investigation into agents targeting p53 is warranted for developing effective treatments for this aggressive breast cancer subtype.
