Early versus delayed palliative/supportive care in advanced cancer: An observational study

Objective: The positive impact of early palliative care interventions in advanced cancer patients has so far been largely evaluated in randomised controlled trials. This study aimed at providing information on the value of early palliative/supportive care, integrated with standard oncologic care, in a real-life setting. Methods: This was a retrospective observational study of 292 advanced cancer patients consecutively admitted at Carpi Hospital in Modena, Italy, between 2014 and 2017. For the purpose of this analysis, patients were classified into two groups (early and delayed palliative/supportive care patients), and analysed for different clinical indicators. Early and delayed palliative/supportive care were classified according to the time elapsed from advanced cancer diagnosis until palliative/supportive care start. Results: A total of 200 patients (68%), with at least three visits, were included in the analyses. The frequency of chemotherapy use in the last 60 days of life was 3.4% and 24.6% in the early and delayed groups, respectively (adjusted OR=0.1; 95% CI 0.0 to 0.4; p=0.002). The estimated survival probability at 1 year was 74.5% (95% CI 65.0% to 85.4%) and 45.5% (95% CI 37.6% to 55.0%), in the early and delayed groups, respectively. Performance status, pain and all the Edmonton Symptom Assessment Scale items, assessed at baseline and at 1 to 12 weeks after the intervention, showed significant improvement over time. However, no between-group differences were found with regard to symptom outcomes. Conclusions: An earlier palliative/supportive care intervention was associated with reduced aggressiveness of therapy, in patients receiving community oncology care. Symptom burden was improved by early palliative/supportive care, independently of the timing of patient referral.
