Abstract
BACKGROUND: Systemic anticancer treatment (SACT) for advanced cancer patients with limited prognosis before death is associated with high toxicity and reduced quality of life. Guidelines discourage this approach as low-value care. However, a significant number of patients continue to receive SACT in the last 30 days of life. MATERIALS AND METHODS: A retrospective study was carried out at the University Hospital Krems, encompassing the analysis of patients who were diagnosed with a solid tumor and died between 2017 and 2021, with a particular focus on the use of end-of-life (EOL) SACT. RESULTS: A total of 685 patients were included in the study. SACT was applied in 342 (49.9%) patients, of whom 143 (41.8%, total population: 20.9%) patients received SACT within the last 30 days of life. Median time from last SACT to death was 44.5 days. The analysis of potential factors impacting the administration of EOL SACT revealed the following significant findings: type of SACT [P < 0.001, targeted therapy odds ratio (OR) 5.09, 95% confidence interval (CI) 2.26-11.48; chemotherapy/targeted therapy OR 3.60, 95% CI 1.47-8.82; immune checkpoint inhibitor OR 2.32, 95% CI 1.37-3.92], no referral to palliative care (PC) (P = 0.009, OR 1.86, 95% CI 1.16-2.96), no admission to PC ward (P < 0.001, OR 2.70, 95% CI 1.67-4.35), and poor Eastern Cooperative Oncology Group (ECOG) performance status (≥2, P < 0.001, OR 3.35, 95% CI 1.93-5.83). CONCLUSION: The timing of SACT near the EOL is significantly influenced by several factors, including the type of SACT, referral to PC services, admission to PC unit, and ECOG performance status. These findings underscore the complexity of treatment decisions in advanced cancer care and highlight the need for personalized, patient-centered approaches that consider both clinical and patient-related factors to optimize care at the EOL.
