Palliative care in the context of immune and targeted therapies: A qualitative study of bereaved carers' experiences in metastatic melanoma.

BACKGROUND: Immune and targeted therapies continue to transform treatment outcomes for those with metastatic melanoma. However, the role of palliative care within this treatment paradigm is not well understood. AIM: To explore bereaved carers' experiences of immune and targeted therapy treatment options towards end of life for patients with metastatic melanoma. DESIGN: An interpretive, qualitative study using a social constructivist framework was utilised. Interviews were recorded, transcribed and analysed using grounded theory methods. SETTING/PARTICIPANTS: Participants (n = 20) were bereaved carers of patients who had received some form of immune and/or targeted therapy at one of three Australian metropolitan melanoma treatment centres. RESULTS: Carers struggled to reconcile the positive discourse around the success of immune and targeted therapies in achieving long-term disease control, and the underlying uncertainty in predicting individual responses to therapy. Expectations that immune and targeted therapies necessarily provide longer-term survival were evident. Difficulty in prognostication due to clinical uncertainty and a desire to maintain hope resulted in lack of preparedness for treatment failure and end of life. CONCLUSION: Immune and targeted therapies have resulted in increased prognostic challenges. There is a need to engage, educate and support patients and carers to prepare and plan amid these challenges. Educational initiatives must focus on improving communication between patients, carers and clinicians; the differences between palliative and end-of-life care; and increased competency of clinicians in having goals-of-care discussions. Clinicians must recognise and communicate the benefit of collaborative palliative care to meet patient and family needs holistically and comprehensively.
