Objective: Needs assessment is the essence of quality cancer survivorship care. The aim of this study was to explore the supportive care needs of breast cancer survivors (BCS) in the first 5 years post treatment.Methods: A mixed-methods approach was employed. A quantitative study included a Supportive Care Needs Survey, which was completed by 250 BCS to identify the level of their needs for help. The quantitative data informed semistructured qualitative interviews undertaken with 60 BCS to explore in detail their posttreatment needs and experiences.Results: 32.4% and 16.8% reported 1 to 5 and greater than or equal to 6 needs for help, respectively. The regression analyses revealed that women within 2 years posttreatment and with higher educational level had higher levels of Psychological and Health Care System/ Information needs. The qualitative data revealed "continuity of care" and "lifestyle advice and self-management" as prominent survivorship concerns. It was shown that determination to continue normal life, social support, and feeling overwhelmed by information were all experienced as important influences on survivors 0 need for help.Conclusions: Posttreatment needs vary with BCS characteristics and to the domains concerned. The approach to posttreatment care needs to be personalized and viable. Various supportive care services are available for cancer survivors, including information support, psychological counseling, practical assistance, and spiritual healing. 6,7 However, many of these services remain underutilized, despite greater efforts to improve the quality of the services. 8 Since publications of the Institute of Medicine report in USA 4 and Cancer Taskforce report in UK, 3 considerable efforts have been made to implement and evaluate a personalized survivorship care plan to facilitate BCS 0 transition from oncologist care to follow-up exclusively with their own primary care physician. However, given that the survivorship care plan is resource-intensive and the available empirical evidence shows very few measureable benefits in outcomes, a survivorship care plan is generally considered to have face validity only in improving communication among health care providers and survivors. 9-11 A better understanding of the supportive care needs and experiences of BCS is essential for identifying avenues for survivorship care enhancement. We still know little about how BCS experience continuity of care at the juncture of completion of primary cancer treatment and moving toward recovery and when and how to best meet
