Background: The Living with Cancer (LWC) patient reported outcome (PRO) instrument evaluates distress from the point of view of the advanced cancer pt. The 7-item Likert survey measures 4 personhood domains (performance status, pain, burden [financial and family], depression) with scores ranging 0-112. In a pilot study of 433 cancer pts at a single center a score of >28 was associated with an increased likelihood of physician’s (blinded) opinion of need for end-of-life care discussions (J Palliative Med 2016). Methods: The LWC instrument is a statistically validated PRO (ASCO Palliative Care Symposium 2016). LWC was administered to 1024 cancer pts receiving non-curative therapy at 7 centers (Regional Cancer Care Associates, NJ) from Sept 2015 - Oct 2016. LWC surveys were linked to the Cota database, which extracts and enriches data from EHRs. Date of survey was used as the start point in time-to-event analysis. Results: 290 (28%) pts expired during the study (median f/u 9.9 months). 267 (26%) pts exceeded the threshold score of 28 defined in the pilot set (28 was also independently this study’s optimal cut point). Pts with an LWC score >28 had inferior 6 and 12 mo overall survival (69% and 54%) vs pts with scores <29 (88% and 73%) (log rank p<0.001). A Cox model demonstrated that LWC score and cancer type were significant (LWC: p<0.001, cancer types (compared to B): GI p<0.001, GU: p=0.013, T: p<0.001, M: p=0.334) A one point score increase in LWC resulted in a 1.8% increase in expected hazard. Among solid tumor pts with LWC >28, 20% died within the next 3 mo and 35% died within the next 6 mo, indicating appropriate timing for hospice and palliative care consults, respectively. Conclusions: Pt responses to the LWC instrument predict survival among advanced cancer pts and may be useful in guiding timing of palliative care consultations.
