The impact of early palliative care on the quality of life of patients with advanced pancreatic cancer: The IMPERATIVE case-crossover study

PURPOSE: Pancreatic cancer is a lethal disease. Many patients experience a heavy burden of cancer-associated symptoms and poor quality of life (QOL). Early palliative care alongside standard oncologic care results in improved QOL and survival in some cancer types. The benefit in advanced pancreatic cancer (APC) is not fully quantified. METHODS: In this prospective case-crossover study, patients ≥ 18 years old with APC were recruited from ambulatory clinics at a tertiary cancer center. Patients underwent a palliative care consultation within 2 weeks of registration, with follow up visits every 2 weeks for the first month, then every 4 weeks until week 16, then as needed. The primary outcome was change in QOL between baseline (BL) and week 16, measured by Functional Assessment of Cancer Therapy – hepatobiliary (FACT-Hep). Secondary outcomes included symptom control (ESAS-r), depression, and anxiety (HADS, PHQ-9) at week 16. RESULTS: Of 40 patients, 25 (63%) were male, 28 (70%) had metastatic disease, 31 (78%) had ECOG performance status 0–1, 31 (78%) received chemotherapy. Median age was 70. Mean FACT-hep score at BL was 118.8, compared to 125.7 at week 16 (mean change 6.89, [95%CI (-1.69–15.6); p = 0.11]). On multivariable analysis, metastatic disease (mean change 15.3 [95%CI (5.3–25.2); p = 0.004]) and age < 70 (mean change 12.9 [95%CI (0.5–25.4); p = 0.04]) were associated with improved QOL. Patients with metastatic disease had significant improvement in symptom burden (mean change -7.4 [95%CI (-13.4 to -1.4); p = 0.02]). There was no difference in depression or anxiety from BL to week 16. CONCLUSION: Palliative care should be integrated early in the journey for patients with APC, as it can improve QOL and symptom burden. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT03837132.
