Prognostic Impact of the Neutrophil/Lymphocyte Ratio (NLR) in the Treatment of First-line Metastatic or Locally Advanced Breast Cancer Treated With CDK4/6 Inhibitor.

NCT05303129 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 165

Last updated 2025-01-20

No results posted yet for this study

Summary

The impact of the inflammatory microenvironment in predicting the benefit of a CDK4/6 inhibitor in the treatment of locally advanced or first line metastatic breast cancer has not yet been studied.

We propose a multicenter prospective study to confirm the prognostic value of pre-therapy NLR on progression-free survival of patients initiating treatment with a CDK4/6 inhibitor combined with hormonal therapy for locally advanced or metastatic HR-pos / HER2-neg breast cancer.

We will also evaluate other markers of inflammation and their prognostic and predictive value for a better response to CDK4/6 inhibitor therapy in combination with hormone therapy in these patients.

Specific blood tests (lymphocyte typing) will be performed during treatment with CDK4/6.
