Background: We aimed to gain insight into the experiences and perceptions of patients with advanced metastatic cancer surrounding palliative radiation therapy (RT).

Methods: In-depth structured interviews were conducted from 9/2016 to 10/2018 with 17 patients with bone or lung metastases receiving their first course of palliative RT. Patient answers about understandings of goals of care and disease prognosis were recorded and analyzed through qualitative content analysis. Medical records were reviewed to obtain demographic and clinical data.

Results: The median age of patients was 64 years (range: 21-82). The median survival from time of metastatic diagnosis was 17.6 months (range: 1-46). When asked about goals of RT, qualitative analysis revealed that half (53%) linked receiving palliative RT to improving their quality of life, however 35% believed RT would completely get rid of their tumor. Words that were used commonly throughout patient answers included alleviating pain (41%), cure (29%), and reducing tumor growth (24%). All patients reported they received their information about goals of care from their medical teams. When asked about prognosis, 53% said prognosis had been discussed with them, whereas 76.5% said they were interested in information about prognosis. When asked “What do you believe lies ahead?,” about half (47%) expressed uncertainty about the future, while others (41%) were focused on the next steps in treatment. In the patients interested in learning more about their prognosis, there was a strong preference for this information to come from their medical teams.

Conclusions: More than half of patients accurately identified the goal of RT as improving their quality of life, however some patients believed that the palliative RT would cure their tumor. This highlights the ongoing gap in patient provider communication and the need for improvement in this area. Inaccurate perceptions of goals of treatment and prognosis may motivate some patients to pursue unnecessarily aggressive treatments, which could affect quality of life without improving survival. Referrals to radiation oncologists present a potential opportunity to reopen discussions on goals of care and prognosis to adjust patient expectations.
