Examining blood cell counts and immune response in triple negative breast cancer

PERCEPTION Trial Protocol: Comparison of Predictive and Prognostic Capacities of Neutrophil, Lymphocyte and Platelet Counts and Tumour-infiltrating Lymphocytes in Triple Negative Breast Cancer

Observational Centre Jean Perrin · NCT04068623

This study is trying to see how blood cell counts and certain markers can help understand treatment responses and outcomes for people with triple negative breast cancer.

What this trial studies

The PERCEPTION study investigates the relationship between various blood cell counts, including neutrophils and lymphocytes, and tumor infiltrating lymphocytes (TILs) in patients with triple negative breast cancer. It aims to analyze these correlations both at baseline and post-surgery, as well as evaluate circulating tumor DNA as a potential predictor of metastatic recurrence. This observational study focuses on understanding how these blood markers can inform treatment responses and outcomes in this aggressive cancer type.

Who should consider this trial

Good fit: Ideal candidates are females over 18 years old diagnosed with non-metastatic, histologically confirmed triple negative breast cancer who have undergone chemotherapy, surgery, and radiation therapy.

Not a fit: Patients who are male or do not have available tumor samples or blood test results at baseline may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into predictive markers for treatment response and recurrence in triple negative breast cancer patients.

How similar studies have performed: While the correlation of these specific markers in triple negative breast cancer has not been thoroughly studied, similar approaches in other cancer types have shown promising results.
