TUMOR
Patients reported their age, gender, educational level (low, elementary to low vocational education; medium, up until medium-level vocational education; high, high vocational or academic education), nationality, and preferred decision-making role by questionnaire. In the local case report forms, the patient’s tumor type and the type of consultation (first/evaluative) were registered; the results of the (positron emission tomography [PET])computed tomography (CT) scan in case of evaluative consultations, patients’ World Health Organization performance status at the time of the consultation (0–4), and the line of therapy that was discussed during the consultation were extracted from the medical record.
