Abstract
BACKGROUND: Immunotherapy has resulted in unprecedented improvements in survival and maintained quality of life for many patients with advanced melanoma. However, durable responses are observed in only a minority of patients, and severe treatment side effects are experienced by 5%-30%. There are no reliable tests that can differentiate between patients who are likely to respond to immunotherapy and those who will not. Hence, new challenges have arisen as clinicians try to facilitate patients in their decision-making regarding immunotherapy. Furthermore, little is known about the real-world patients' experience and understanding of immunotherapy outside the clinical trial setting. Here, we explore the perspectives of patients undergoing immunotherapy for melanoma and focus on factors that influenced their treatment decision-making. MATERIALS AND METHODS: Twenty-three in-depth semistructured interviews were conducted with patients receiving pembrolizumab for stage IV melanoma at an Australian public cancer hospital. Patients were recruited at a range of time points after commencing therapy, and their experience of treatment was explored. Interviews were audio recorded, transcribed verbatim, coded, and analyzed thematically. RESULTS: Immunotherapy is viewed as a symbol of hope, with high-profile anecdotes reinforcing this perception. Only a minority of patients expressed a good understanding of the likely efficacy and potential treatment side effects. Patients are reliant on their clinicians' recommendation regarding immunotherapy treatment decisions. CONCLUSION: Novel treatments such as immunotherapy provide significant hope for patients. This may influence their preference for immunotherapy over and above the usual considerations of the trade-off between efficacy and toxicity. Careful counsel and individualized patient resources may further facilitate treatment decision-making. IMPLICATIONS FOR PRACTICE: This study highlighted some of the misconceptions held by patients that need to be addressed when discussing the possibility of receiving treatment with immunotherapy for advanced melanoma. Patients placed a lot of importance on high-profile anecdotes rather than truly understanding likely outcomes of treatment based on personal circumstances. The majority of patients had a poor understanding of the potential side effects and long-term implications of treatment with immunotherapy. Careful counsel is required in order to facilitate informed decision-making about treatment and to ensure possible side effects are known and appreciated. Further research is needed to develop tools to aid decision-making in everyday clinical practice.
