Patients in study arm A will receive transarterial radioembolisation one time only. Patients in study arm B will receive transarterial chemoembolisation every 4 to 6 weeks until complete tumor devascularisation is observed or disease progression or intolerable toxicity occur. At the time of local tumor progression patients will be offered the other treatment respectively (either SIRT or DSM-TACE) as part of the study.
