Chemotherapy Near the End of Life in Onco-Hematological Adult Patients

Abstract

Objective: The use of chemotherapy near the end of life is not advisable. There are scarce data in Europe but shows signs of aggressiveness. We designed this study to analyze the proportion of onco-hematological patients receiving chemotherapy within their last 2 weeks of life as well as starting a new chemotherapy regimen in the 30 days prior to death.

Methods: A retrospective observational study was conducted in a tertiary hospital. Adults who died of an onco-hematological neoplasia while hospitalized between April 2017 and March 2018 were included. We assessed the use of chemotherapy over the course of the last 14 days of life, defined as the administration of at least one dose of chemotherapy. We also examined the proportion of patients starting a new chemotherapy regimen in the last 30 days of life.

Results: A total of 298 inpatients died in the Hematology and Oncology units. During the last 14 days, 28.2% (n = 11) of hematological and 26.3% (n = 68) of oncological patients received chemotherapy; the overall rate was 26.5% (n = 79). Furthermore, the proportion of patients starting a new chemotherapy regimen in the last 30 days of life was high (20.5% and 20.8%, respectively). Female gender (odds ratio [OR] = 1.99, 95% confidence interval [CI] = 1.18-3.35) and age <45 (OR = 2.68, 95% CI = 1.05-6.88) were associated with higher rates of chemotherapy.

Conclusion: The proportion of patients receiving chemotherapy in the last 14 days of life was high, as well as the proportion of patients starting a new regimen in their last 30 days. This was indicative of excessive aggressiveness at the end-of-life care.
