The value of immunotherapy for survivors of stage IV non-small cell lung cancer: patient perspectives on quality of life

 The aim of this study was to examine what personally mattered to 24 patients who received immuno-oncology (IO) therapy for stage IV non-small cell lung cancer(NSCLC),as well as their families and friends,to understand how they evaluated their cancer treatments and the determinants of the quality of life (QoL) of long-term survivors. Methods Ethnographic research was conducted with 24 patients who had responded to IO (pembrolizumab, nivolumab, atezolizumab, or durvalumab) for stage IV NSCLC, and their families and friends, evenly split among field sites in Denmark, the USA, and the UK. Data were collected using in-depth qualitative interviews, written exercises, and participant observation. Data analysis methods included interpretative phenomenological analysis, coding, and the development of grounded theory. Researchers spent 2 days with participants in their homes and accompanied them on health-related outings. Results Our findings reveal that long-term survivors on IO experienced their journey in two phases: one in which their cancer had taken over their lives mentally, physically, and spiritually, and another in which their cancer consumed only a part of their everyday lives. Patients who survived longer than their initial prognosis existed in a limbo state in which they were able to achieve some semblance of normalcy in spite of being identified as having a terminal condition. This limbo state impacted their life priorities, decision-making, experience of patient support, and health information-seeking behaviors, all of which shaped their definitions and experience of QoL. Conclusions The results of this study,which identify the specific challenges of living in limbo,where patients are able to reclaim a portion of their pre-cancer lives while continuing to wrestle with a terminal prognosis, may inform how cancer research can more effectively define and measure the QoL impacts of IO treatments. Also, they may identify approaches that the cancer community can use to support the needs of patients living in a limbo state.These experiences may not be adequately understood by the cancer community or captured by existing QoL measures, which were designed prior to the emergence ofI O and without sufficient incorporation of contextual, patient-driven experience. Implications for Cancer Survivors Increased awareness of the specific experiences that come with long-term survival on IO may directhowresourcesshouldbespentforcancersupportforpatientsandtheirfamilies.ExpandinghowQoLisevaluatedbasedon patients’ lived experiences of IO can reflect a more accurate depiction of the treatment’s benefits and harms.
