Pilot Study of the Predictive Value of TREM1 Expression and Activation in Inflammation and Radio-induced Mammary Fibrosis (TREM-1)

20. juni 2022 oppdatert av: Centre Francois Baclesse, Luxembourg
Breast cancer is the most common cancer in the world. Half of patients with such cancer are treated with radiation therapy. Some patients will develop cutaneous or subcutaneous fibrosis, more or less bothersome. Several studies have shown a correlation between an inflammatory reaction and a protein, called TREM-1. But to date, no link has been proven between TREM-1 and inflammation / fibrosis in the phenomena of fibrosis induced by radiotherapy in patients with breast cancer. Our study aims to understand the involvement of this TREM-1 protein in the development of fibrosis or radio-epidermis in patients with breast cancer.
