ABSTRACT
PURPOSE:
Breast cancer patients receive treatment recommendations from multidisciplinary tumour boards. To determine the consequences of patients' refusal of such recommendations, we analysed the database of the Centre for Breast Cancer at the Ortenau Clinic in Offenburg, Germany.METHODS:
A total of 4315 patients with non-metastatic primary breast cancer, treated between 1997 and 2019, were analysed with descriptive analyses, Kaplan-Meier survival analyses, and Cox regression analyses regarding the effects of their refusal.RESULTS:
About 10.7% of the patients rejected the treatment advice. These were significantly elderly (F = 74.4; p < 0.001; one-way ANOVA), with greater tumour size (F = 36.7; p < 0.001; one-way ANOVA), a higher number of affected lymph nodes (F = 4.2; p = .039; one-way ANOVA), and more poorly differentiated tumours (χ2 = 16.8; df = 2; p < 0.001). The refusal of adjuvant treatment resulted in higher rates of local recurrences (χ2radiotherapy = 109.1; df = 1; p < 0.001, χ2chemotherapy = 18.3; df = 1; p < 0.001, χ2endocrine = 32.5; df = 1; p < 0.001) and poorer overall survival (χ2radiotherapy = 184.9; df = 6; p < 0.001; χ2chemotherapy = 191.8; df = 6; p < 0.001).CONCLUSIONS:
All parts of the adjuvant treatment of breast cancer are clearly associated with improvements regarding disease-free and overall survival. To answer open questions about the background of patients' refusal, an analysis of prospective data collections seems necessary. In addition, patient communication should be improved so that patients understand the background of the multidisciplinary tumour board and the potential consequences of their refusal.Palabras clave
