Highlights
- Advanced prostate cancer is a highly stressful situation for patients and spouses.
- Spouses are often involved in decision making about prostate cancer treatment.
- Couples agree on either quality of life or life expectancy as the goal of therapy.
- Deteriorations in emotional control and motivation were most frequently reported.
- Spouses adapt their treatment goals to the disease situation.
The aim of this study was to evaluate the role of spouses and the relevance of quality of life (QoL) and life expectancy (LE) in the treatment decision-making process of patients with advanced prostate cancer (CaP).
