Design outcomes

Primary

MeasureTime frame
Treatment response regarding: • Patient reported outcomes: Quality of life (FACT-G) and Fatigue (FACIT-F), • Adherence to chemotherapy and endocrine therapy, • Progression-based outcomes: Invasive Disease-Free Survival (IDFS), Distant Relapse-free Survival (DRFS), Breast Cancer Specific Survival (BCSS) and Overall Survival (OV). We will conduct analyses of combined response (best cases) as well as of response on single outcomes and time points. All analyses will be exploratory. Time Points: T0=Baseline (after diagnosis), T1= after ending of the neo-/adjuvant chemotherapy, T2=after ending of all adjuvant treatments, T3=1-year-follow-up, T4=2-year-follow-up, T5=5-year-follow-up, T6=10-year-follow-up. Predictors: • Socio-demographics: age, education • Cancer data: time of diagnosis, histology, recurrence, previous oncological disease, TNM-staging, grading, menopausal state, hormone receptor state, hereditary risk score • Comorbidity: HRQL-CI, ECOG, Karnofsky-performance status scale • Coping: Stress perception (QSC), depression (CESD-SF10), hopelessness (BH-NEG), anxiety (PROMIS-SF4), progression anxiety (FRRS), emotion regulation (ERQ), sleep disorders (PROMIS-SF4), spirituality (FACIT-SP), social support (BSSS) • Lifestyle / environmental factors: alcohol and smoking behavior, medication, exercise (IPAQ) and diet (MEDAS), body mass index, radiation exposure • Oncological therapies (pre- and postoperative) • Side effects: adverse events (MSAS / CTCAE) • Complementary therapies: CAM-beliefs (CHBQ), interest in CAM (VAS), use of CAM (I-CAM-Q) • Satisfaction with therapy (CSQ) • Study center.
