Abstract
CONTEXT: Many advanced patients with cancer have unrealistic prognostic expectations. OBJECTIVES: We tested whether offering life expectancy (LE) statistics within palliative chemotherapy (PC) education promotes realistic expectations. METHODS: In this multicenter trial, patients with advanced colorectal and pancreatic cancers initiating first or second line PC were randomized to usual care versus a PC educational tool with optional LE information. Surveys at two weeks and three months assessed patients' review of the LE module and their reactions; at three months, patients estimated their LE and reported occurrence of prognosis and end-of-life (EOL) discussions. Wilcoxon tests and proportional odds models evaluated between-arm differences in LE self-estimates, and how realistic those estimates were (based on cancer type and line of treatment). RESULTS: From 2015 to 2017, 92 patients were randomized to the intervention and 94 to usual care. At baseline most patients (80.9%) wanted "a lot" or "as much information as possible" about the impact of chemotherapy on LE. Among patients randomized to the intervention, 52.0% reviewed the LE module by two weeks and 66.7% by three months-of whom 88.2% reported the information was important, 31.4% reported it was upsetting, and 3.9% regretted reviewing it. Overall, patients' LE self-estimates were very optimistic; 71.4% of patients with colorectal cancer estimated greater than five years; 50% pancreatic patients estimated greater than two years. The intervention had no effect on the length or realism of patients' LE self-estimates, or on the occurrence of prognostic or EOL discussions. CONCLUSIONS: Offering LE information within a PC educational intervention had no effect on patients' prognostic expectations.
