Abstract Introduction. Early integration of palliative care alongside oncology is being increasingly recommended, although the strategies and models for integration remain poorly defined. We solicited the opinions of patients and caregivers who participated in a randomized trial of early palliative care versus standard oncology care, regarding the respective roles of their oncologist (both groups) and palliative care physician (early palliative care group). Materials and Methods. The study was performed at a comprehensive cancer center. Forty-eight patients (26 intervention, 22 control) and 23 caregivers (14 intervention, 9 control) were recruited purposefully at trial end. One-on-one, semistructured qualitative interviews were conducted and analyzed using grounded theory. Results. The themes resulting from the analysis fell into three categories: the focus of care, the model of care delivery, and the complementarity between teams. The focus of care in oncology was perceived to be disease-centered, with emphasis on controlling disease, directing cancer treatment, and increasing survival; palliative care was perceived to be more holistic and person-focused, with an emphasis on symptom management. Oncology visits were seen as following a structured, physician-led, time-constrained model in contrast to the more fluid, patient-led, flexible model experienced in the palliative care clinic. No differences were found in the descriptions of oncology between participants in the intervention and control groups. Participants in the intervention group explicitly described the roles of their oncologist and their palliative care physician as distinct and complementary. Conclusion. Participants perceived the respective roles of their oncologist and palliative care physician as discrete, important, and complementary for the provision of excellent cancer care.
