Clinical Characteristics in Patients with Triple Negative Breast Cancer

Area of Science:

• Oncology
• Genetics
• Epidemiology

Background:

• Triple-negative breast cancer (TNBC) is an aggressive subtype with distinct clinical characteristics.
• Identifying genetic susceptibility and risk factors is crucial for targeted interventions.
• Understanding TNBC patient demographics and prior health history aids in risk stratification.

Purpose of the Study:

• To compare clinical features of TNBC versus non-TNBC patients.
• To investigate genetic susceptibility and risk factors associated with TNBC.
• To identify specific populations at higher risk for TNBC.

Main Methods:

• Retrospective analysis of an institutional database.
• Inclusion of patients diagnosed with invasive breast cancer between January 2010 and May 2016.
• Statistical comparison of demographic and clinical data between TNBC and non-TNBC groups.

Main Results:

• Out of 1964 patients, 190 (10%) had TNBC.
• TNBC was more prevalent in African American and Asian patients (p = 0.0003).
• BRCA1/BRCA2 mutations (p < 0.0001, p = 0.0007) and prior breast cancer history (p = 0.0003) were significantly associated with TNBC.

Conclusions:

• Asian ancestry, prior breast cancer, and BRCA1/BRCA2 mutations are positively associated with TNBC.
• Enhanced understanding of TNBC risk factors is needed for improved surveillance and prevention.
• Further research can inform the development of more effective TNBC treatments.
