Abstract:
Breast cancer is a heterogeneous disease composed of different subtypes, characterized by their different clinicopathological characteristics, prognoses and responses to treatment. In the past decade, significant advances have been made in the treatment of breast cancer sensitive to hormonal treatments, as well as in patients whose malignant cells overexpress or amplify HER2. In contrast, mainly due to the lack of molecular targets, little progress has been made in the treatment of patients with triple-negative breast cancer. Recent improved understanding of the natural history, pathophysiology, and molecular features of triple-negative breast cancers have provided new insights into management and therapeutic strategies for women affected with this entity. Ongoing and planned translational clinical trials are likely to optimize and improve treatment of women with this disease.
Insights
Triple-negative breast cancer (TNBC) lacks molecular targets, hindering treatment progress. Recent insights into TNBC biology are guiding new therapeutic strategies and clinical trials for improved patient outcomes.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Breast cancer is a complex disease with diverse subtypes.
- Hormone-sensitive and HER2-positive breast cancers have seen treatment advances.
- Triple-negative breast cancer (TNBC) treatment has lagged due to a lack of molecular targets.
Purpose of the Study:
- To review recent advances in understanding TNBC.
- To explore new insights into TNBC pathophysiology and molecular features.
- To identify emerging therapeutic strategies for TNBC management.
Main Methods:
- Literature review of recent studies on breast cancer subtypes.
- Analysis of molecular and pathophysiological data for TNBC.
- Examination of ongoing and planned translational clinical trials for TNBC.
Main Results:
- Significant progress in treating hormone-sensitive and HER2-amplified breast cancers.
- Limited therapeutic options for TNBC historically.
- New understanding of TNBC natural history and molecular landscape.
Conclusions:
- Improved knowledge of TNBC is crucial for developing effective treatments.
- Translational clinical trials are essential for optimizing TNBC therapy.
- Future strategies will focus on molecular targets and personalized approaches for TNBC.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy.
