INTRODUCTION: Early integration of palliative care and advance care planning (ACP) play an increasingly important role in the treatment of patients with advanced cancer. Advance directives (ADs) and patients' preferences regarding End-of-life (EoL) care are important aspects of ACP. In the outpatient setting, the prevalence of those documents and EoL care wishes are not well investigated and changes in the longitudinal course are poorly understood. METHODS: From June 2020 to August 2022, 67 outpatients with advanced solid tumors undergoing palliative cancer therapy were interviewed on the topic of ACP in a longitudinal course. From this database, the prevalence of ADs, health care proxy, EoL care wishes and the need for counseling regarding these issues were collected. In addition, EoL care wishes were examined for their stability. RESULTS: 51 patients (76.1%) reported having ADs, and 41 patients (61.2%) reported having a health care proxy. 19 patients (37.3%) with ADs and 11 patients (68.7%) without ADs indicated a wish for counseling. Reported EoL care wishes remained stable over a period of approximately 6 month. Nevertheless, intraindividual changes occurred over time within the different EoL care preferences. The desire for resuscitation and dialysis were significantly higher in men than in women (resuscitation: 15 of 21 men (71.4%) vs. 9 of 22 women (40.9%), odds ratio [OR] 3.611, 95% confidence interval [CI], 1.01 to 12.89, p=0.048; dialysis: 16 of the 23 men (69.6%) vs. 9 of the 25 women (36.0%), OR 4.063, 95% CI, 1.22 to 13.58, p= 0.023). CONCLUSION: Our results show a reasonably high percentage of ADs and health care proxies in our study cohort. The observed stability of EoL requests encourages implementation of structured queries of ADs and health care proxy for outpatients undergoing palliative treatment. Our data suggest that gender-specific characteristics should be further investigated in this context.
