• Main study objective:
  The main objective of this project is to determine the preferences of patients and oncologists for the characteristics (attributes) of the treatment for renal cell carcinoma (RCC) in Spain and Portugal. In addition, factors contributing to their preferences will be evaluated.
• Outcomes:

• Data analysis plan:
  A descriptive analysis of the socio-demographic and clinical characteristics of the participants will be performed. On the other hand, the results of the DCE (Discrete Choice Experiment) will be analyzed applying a mixed logit model. The influence of individual characteristics on participants' preferences will be explored through multiple linear regression. On the other hand, the correlation between the responses of patients and oncologists will be evaluated. In addition, the willingness to accept a less desirable risk or treatment characteristic in exchange for clinical benefit (MAR) as well as willingness to pay (WTP) will be analyzed.
