83 Background: Increasing recognition that high-quality end of life care is essential has resulted in internationally endorsed metrics allowing assessment of interventions at the end of life. Median survival for mCRC patients has improved to more than 24 months resulting in increased opportunity to undergo interventions for symptom relief at the end of life. We explored patterns of palliative interventions (chemotherapy, radiotherapy, surgery, endoscopy, drainage procedures) and outcomes in mCRC patients. Methods: A retrospective review was undertaken of all mCRC patients referred to the palliative care service from 2000 to 2010 at a tertiary cancer center in Toronto, Canada. Descriptive statistics, survival analysis and regression were employed. Results: A total of 542 patients were included of whom 52.8% were male, mean age was 62.8 years and 44.6% had stage 4 disease at diagnosis. Over the course of their disease 93.9% had an intervention at any time after their diagnosis including 27.5% of patients undergoing palliative surgery, 77% of patients had an intervention in the last year of life and 19.1% had an intervention in the last 30 days of life. The percentage of patients receiving interventions within the last 14 days of life were 1.23% for chemotherapy, 4.6% for radiotherapy, 0.5% for surgery, 10.4% for endoscopy and 23% drainage procedures. The mean time between referral to palliative care and death was 7 months (SD 10.4). For patients who received chemotherapy, the mean time between last chemotherapy and death was 9.5 months (SD 14.9). Overall survival for patients who did not receive chemotherapy was 28 months (SD 33) compared with 40 months (SD 32) for those who received chemotherapy. Regression analysis for risks of dying within 30 days of chemotherapy was limited by a low event rate. Increasing age was significantly associated with a lower risk of dying within 30 days of chemotherapy. Conclusions: In their final months of life, palliative mCRC patients undergo a significant number of interventions aiming to improve quality of life. These require considerable multi-disciplinary input with ramifications for quality care, planning for service provision and funding.
