Tumor biology in older breast cancer patients – What is the impact on survival stratified for guideline adherence? A retrospective multi-centre cohor…
2015
Abstract Purpose The tumor biology of older breast cancer patients (oBCP) is usually less aggressive, however applied adjuvant treatment is often less potent resulting in an impaired disease free survival and overall survival in this group. This study tries to answer the following questions for the biological subtypes of oBCP (70+ y): (1) Is there a significant difference in the distribution of the biological subtypes of oBCP vs younger breast cancer patients (yBCP; 50–69 y)? (2) Which biological subtype has the highest rate of non-guideline-adherent-treatment (GL−) among oBCP? (3) Is a single GL− (i.e. radiotherapy/surgery/endocrine-therapy/chemotherapy) significantly associated with the s…
Aggressive Intrinsic Subtypes in Breast Cancer: A Predictor of Guideline Adherence in Older Patients With Breast Cancer?
2015
Treatment side effects, comorbidities, and guideline-adherent treatment (GL+) influence the oncologic outcome of older breast cancer patients (oBCP) (age ≥ 70 years). The focus of this analysis was to investigate the associations among tumor characteristics, guideline adherence, and outcome and to compare these associations between younger breast cancer patients (yBCP) (age 50-69 years) and oBCP.This is a retrospective multicenter cohort study with 17 participating certified breast cancer centers. The analysis of 10,897 patient records collected from 1992 to 2008 for GL+ and clinical outcome was performed. Tumor and patient characteristics and their associations with GL+ were compared betwe…
Standard treatment of female patients with breast cancer decreases substantially for women aged 70 years and older: a German clinical cohort study
2010
Standard treatment of patients with breast cancer decreases with age and older persons are mostly excluded from clinical trials. We hypothesized that non-adherence to treatment guidelines occurs for women agedor =70 years and changes overall survival (OAS) and disease-free survival (DFS).We enrolled 1922 women agedor =50 years with histologically confirmed invasive breast cancer treated at the University of Ulm from 1992 to 2005. Adherence to guidelines and effects on OAS and DFS for women agedor =70 years was compared with that for younger women (50-69 years).Women70 years less often received recommended breast-conserving therapy (70-79 years: 74%-83%;79 years: 54%) than women agedor =69 y…
