Prevalence, Correlates, & Outcomes of Chemotherapy for Patients with End-Stage Gastrointestinal Cancers Holly G. Prigerson, PhD Renee C. Maciejewski, BS Manish A. Shah, MD Yuhua Bao, PhD Paul K. Maciejewski, PhD Center for Research on End-of-Life Care Weill Cornell Medicine Learning Objectives After this presentation, participants should know the: prevalence patient profile outcomes associated with chemotherapy use for GI cancer patients who are nearing death Presented by: Holly G. Prigerson, Ph.D Presentation Outline This talk will present data on the: a. frequency b. correlates c. harms & benefits of chemotherapy use in patients in their final months of life Presented by: Holly G. Prigerson, Ph.D. Frequency of chemotherapy use in GI cancer patients near death Administration codes from SEER-Medicare data reveal that: Stage IV pancreatic cancer patients diagnosed 2006 2011 who died within a year of their diagnosis (total N=7998): 35% chemotherapy Stage IV pancreatic cancer patients diagnosed in 2011 and then died in 2012 (total N=1270): 37% chemotherapy Presented by: Holly G.

From Coping with Cancer NCI R01 data: Sites: Yale Cancer Center, Dana-Farber/BWH, MGH, University of Texas Southwestern (Parkland, Simmons), Pomona Valley Hospital, New Hampshire Oncology Hematology, Weill Cornell/Meyer, University of New Mexico, Massey, Memorial Sloan-Kettering Cancer Centers Patients: GI cancer patients distant mets and refractory to at least 1 line of chemotherapy a median of 4 months from death CwC I (2002-2008): 50% patients using chemotherapy at baseline assessment Presented by: Holly G. Prigerson, Ph.D From Coping with Cancer NCI R01 CwC II data (2010-2015): The question Are you currently receiving chemotherapy? The answer: pre-restaging scan = 90% receiving chemotherapy post-restaging scan = 81% receiving chemotherapy In the medical chart abstraction following restaging scan: 86% current chemotherapy use Across pre, post, and the med chart: 94%! receive chemotherapy Presented by: Holly G.

Patients Higher Quality of Life Near Death Stratified by Baseline Performance Status and Chemotherapy Use ECOG indicates Eastern Cooperative Oncology Group. Performance status was measured by ECOG score as follows: 1. symptomatic, ambulatory 2. symptomatic, in bed less than 50% of the time 3. symptomatic, in bed more than 50% of the time 69% 44% Conclusions Prevalence of chemotherapy in GI cancer patients within months of death is: frequent (~ 50%) nearly universal at academic medical centers becoming more common Presented by: Holly G. Prigerson, Ph.D Conclusions GI cancer patients with progressive metastatic disease receiving chemo are more likely to be: younger married better educated > academic cancer clinics; < community cancer clinics Presented by: Holly G. Prigerson, Ph.D Conclusions GI cancer patients with progressive metastatic disease who are receiving chemo are more likely than those who do not to: have better baseline performance status, QoL want life-prolonging care, including chemo even if only enhancing survival by a week lower rates of DNR order completion, terminal illness acknowledgment, & EoL discussions Presented by: Holly G. Prigerson, Ph.D
Conclusions GI cancer patients with progressive metastatic disease who get chemo are at risk in their last week of: CPR feeding tube ICU stay and death hospice stays of only a few days not dying at home or in preferred place of death Presented by: Holly G. Prigerson, Ph.D Conclusions GI cancer patients near death who get chemo are likely to have: good performance status and, therefore, have the most to lose as they are: are more likely to have poor quality of death Presented by: Holly G. Prigerson, Ph.D We appreciate this opportunity to present at ASCO 2016 GI Cancers Symposium! Thank You! Presented by: Holly G.
