175 Background: The Palliative and Supportive Oncology Tumor Board was developed in 2015 to provide an interdisciplinary forum for discussion and management of patients with complex or refractory symptoms from advanced cancer. The board meets monthly and consists of medical, surgical, and radiation oncologists, interventional radiologists, pain management, palliative care specialists, residents, and fellows. Here, we assess the impact of the tumor board on the care of these patients. Methods: Electronic records of advanced cancer patients discussed at the tumor board from January 2015 to December 2015 were analyzed. We extracted data regarding sociodemographics, primary cancer site, pain interventions delivered, palliative care services utilized, and readmissions. Results: Thirty-two patients were presented at the tumor board over twelve months. The median age was 60 years (range 26-89); 47% were male. Primary cancer site included multiple myeloma (n = 11), gastrointestinal (n = 9), genitourinary (n = 5), breast (n = 2), lung (n = 2), skin (n = 1), and unknown origin (n = 2). At the time of discussion, 16 patients were hospitalized and 18 were in the ambulatory setting. Recommendations from the tumor board included altering medication regimen (n = 4), discussing eligibility to receive an anesthetic block (n = 7), undergoing vertebroplasty (n = 9), and planning palliative radiation treatment (n = 19). Patients were seen by specialists from pain (n = 21), interventional radiology (n = 14), neurosurgery (n = 9), palliative care (n = 20), radiation oncology (n = 21), or medical oncology (n= 32) within one day of their case presentation at the tumor board. Seven patients were transferred to the inpatient palliative care unit within a day of their tumor board discussion. Five patients were readmitted to the hospital within 30 days due to uncontrolled pain or other symptoms. Conclusions: The palliative and supportive oncology tumor board was well received by clinicians overall. It fostered interdisciplinary collaboration and supported comprehensive management of pain and other symptoms, as evidenced by the mix of cases discussed and the short time within which patients were seen after presentation by the participating specialists.
