TUMORS
Medical oncologists and medical oncologists in training, who were recruited through existing networks, were eligible when treating patients with metastatic or inoperable tumors. Patients scheduled for an initial or evaluative consultation to discuss the start, (dis)continuation, or adjustment of palliative systemic treatment in 7 Dutch hospitals were invited for participation. Eligible patients were diagnosed with metastatic or inoperable tumors for which the indicated median life expectancy without disease-targeted treatment was less than 12 mo and palliative systemic treatment would not offer a median survival benefit of more than 6 mo.
