Investigation of the change in the biological structure of the tumor in metastatic breast cancer
Medical Science and Discovery
Objective: When metastasis develops in some breast cancer patients, hormone receptors (HR) and Human Epidermal Growth Factor-2 (Her-2) status can change and the tumor alters its character. We tried to determine the rate of these changes in tumor biology in 110 patients that we followed in our clinic and performed the change of the biopsy from the metastatic site (re-bx). We aimed to determine the biological changes of tumors and, contribute to the literature by examining the relationship ofdoi:10.36472/msd.v8i3.503 fatcat:sssfnupsffaotopwyefpb7yhtu
