Background: The administration of chemotherapy at the end of life is considered an aggressive life-prolonging treatment. The use of unnecessarily aggressive therapy in elderly patients at the end of life is an important health-care concern. Objective: To explore the impact of palliative care consultation (PCC) on chemotherapy use in geriatric oncology inpatients in Japan by analyzing data from a national database. Methods: We conducted a multicenter cohort study of patients aged ≥65 years, registered in the Japan National Administrative Healthcare Database, who died with advanced (stage ≥3) lung, stomach, colorectal, liver, or breast cancer while hospitalized between April 2010 and March 2013. The relationship between PCC and chemotherapy use in the last 2 weeks of life was analyzed using χ2 and logistic regression analyses. Results: We included 26 012 patients in this analysis. The mean age was 75.74 ± 6.40 years, 68.1% were men, 81.8% had recurrent cancer, 29.5% had lung cancer, and 29.5% had stomach cancer. Of these, 3134 (12%) received PCC. Among individuals who received PCC, chemotherapy was administered to 46 patients (1.5%) and was not administered to 3088 patients (98.5%). Among those not receiving PCC, chemotherapy was administered to 909 patients (4%) and was not administered to the remaining 21 978 patients (96%; odds ratio [OR], 0.35; 95% confidence interval, 0.26-0.48). The OR of chemotherapy use was higher in men, young–old, and patients with primary cancer. Conclusion: Palliative care consultation was associated with less chemotherapy use in elderly Japanese patients with cancer who died in the hospital setting.
