Psychological distress and quality of life in Chinese early-stage breast cancer patients throughout chemotherapy

Breast cancer survivors with psychological problems have higher mortality than those without. Therefore, it is important to monitor and manage their psychological status. This study mainly aimed to dynamically estimate the prevalence of anxiety and depression and to clarify the factors associated with anxiety and depression of patients undergoing adjuvant chemotherapy. The secondary objective was to investigate the relationship between depression and anxiety and quality of life (QOL) in Chinese early-stage breast cancer patients.
