Tumor biology in older breast cancer patients – What is the impact on survival stratified for guideline adherence? A retrospective multi-centre cohort study of 5378 patients

“…In the oBCP, side effects have led to a number of publications on treatment efficacy [19,21,24,40], consenting [23], quality of life [18,25], increasing the rate of therapy completion [17] and preoperative chemotherapy [41]. Our study follows up on these findings.…”

To our knowledge, our study is the first comprehensive description of an unselected cohort of this particular subgroup of patients.…”
