Immunotherapy has improved survival for patients with melanoma and non-small cell lung cancer (NSCLC). Yet, as responses vary widely, immunotherapy also introduces challenges in prognostic communication. In this study, we sought to explore how patients and caregivers learned about the goal of immunotherapy and their experience of living with uncertainty. We conducted a qualitative study of patients with stage III or IV melanoma or stage IV NSCLC within 12 weeks of initiating or 12 months of discontinuing immunotherapy, and their caregivers. We conducted in-depth interviews with participants to explore how they learned about immunotherapy from oncology clinicians and how they experienced uncertainty. We used a framework approach to analyze interview transcripts and synthesized concepts into themes. Forty-two patients and 10 caregivers participated; median age was 67 years and most were male (68%), white (95%), married (61%), and had melanoma (62%). We identified four themes: (1) the oncology team shaped participants' hopeful expectations of immunotherapy, including as a potential cure among those with melanoma; (2) distress related to prognostic uncertainty particularly affected patients who experienced toxicity or progressive disease; (3) patients who did not have long-term responses experienced overwhelming disappointment; and (4) some patients and caregivers had conflicting preferences for prognostic information. Participants provided suggestions to improve education and underscored unmet psychosocial needs. Patients and caregivers held optimistic expectations of immunotherapy, which resulted in heightened disappointment among the subset with progression or toxicity. Clinicians should elicit information preferences of both patients and caregivers, as these may be disparate. Our results highlight the need to optimize prognostic communication and support for living with uncertainty among patients receiving immunotherapy.
