Effect of a Mentor-based, Supportive-expressive Program on Survival in Metastatic Breast Cancer

Breast cancer is the most prevalent cancer in women and annually accounts for 10% of new malignancies worldwide. In mainland China, approximately 169,000 females are diagnosed with breast cancer every year and constitute 12.25% of the breast cancer incidents worldwide. Additionally, 30% of early breast cancer turns metastatic, which is often incurable. Different from women with early breast cancer, women with metastatic breast cancer(MBC)must receive lifelong treatment, experience higher levels of emotional/physical distress, and feel frequent uncertainty about their health/possible death. They are also challenged to manage distressing adverse effects induced by different adjuvant treatments and experience heavy self-care demands during the transition period from being a patient to being a survivor. Thus, specific interventions to help women with metastatic breast cancer to recover from this traumatic event have been designed, and one of these is supportive-expressive group therapy(SEGT).SEGT has been found to achieve improvement in anxiety, depression, quality of life (QoL), family functioning, and satisfaction with treatment. However, the effect of SEGT on survival is inconsistent. Initial studies examining SEGT have reported a mean survival advantage of 18 months, however, these findings could not later be replicated.Yet, no study has reported a survival disadvantage for those given SEGT. In addition, we found no published articles on the application of SEGT among women with MBC in China. Owing to this dearth of previous research, it is unclear whether this therapy would exhibit positive effects within Chinese culture. Thus, we developed a "Be Resilient to Breast Cancer"(BRBC) program that is culturally tailored for Chinese females with MBC. This program was adapted from SEGT and is designed to increase resilience(defined as the capacity to bounce back after encountering a traumatic event) and QoL, decrease emotional and physical distress(allostatic load), and ev
