Immune Tumor Stroma Factors and Pathologic Complete Response After Neoadjuvant Chemotherapy in Early Breast Cancer

NCT07407244 · Status: ACTIVE_NOT_RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 268

No results posted yet for this study

Summary

This prospective cohort study aims to identify immune-related predictive factors of response to neoadjuvant chemotherapy in patients with early breast cancer. The study will evaluate immune markers in tumor stroma and blood samples collected before treatment to determine their association with complete pathological remission (pCR). In addition, circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA) will be analyzed to explore their correlation with treatment response. The results may contribute to improved selection of patients who are most likely to benefit from neoadjuvant chemotherapy.

Conditions

Interventions

DRUG

Neoadjuvant Chemotherapy

Standard neoadjuvant chemotherapy administered to patients with early breast cancer according to institutional protocols. Treatment is not experimental and is part of routine clinical care. Immune-related tumor stroma factors and blood biomarkers will be analyzed in relation to pathological complete response (pCR) and circulating tumor cells/circulating tumor DNA.
