Prognostic Awareness, Palliative Care Use, and Barriers to Palliative Care in Patients Undergoing Immunotherapy or Chemo-Immunotherapy for Metastatic Lung Cancer.

Background and Objectives: This study describes patients' prognostic awareness and palliative care use in the setting of immunotherapy for metastatic non-small cell lung cancer (mNSCLC). Design: We surveyed 60 mNSCLC patients receiving immunotherapy at a large academic medical center; conducted follow-up interviews with 12 survey participants; and abstracted palliative care use, advance directive completion, and death within a year of survey completion from the medical record. Results: Forty seven percent of patients surveyed thought they would be cured; 83% were not interested in palliative care. Interviews suggested oncologists emphasized therapeutic options when discussing prognosis and that commonly used descriptions of palliative care may exacerbate misperceptions. Only 7% had received outpatient palliative care and 8% had an advance directive a year after the survey; only 16% of the 19 patients who died had received outpatient palliative care. Conclusions: Interventions are needed to facilitate prognostic discussions and outpatient palliative care during immunotherapy. Clinical Trial Registration Number NCT03741868.
