[Combined therapies including interventional radiology].

Interventional tumor therapies are a therapeutic option that is increasingly applied in the treatment of malignant diseases. Thermoablation of primary and secondary liver tumors is the most widely used of them, and owing to the promising results it has given, it is becoming an increasingly well-accepted treatment procedure. These interventional radiological tumor therapies must be evaluated in comparison with standard therapies, and particularly in comparison with surgical resection, radiotherapy, and systemic chemotherapy. This comparative approach to the evaluation of different therapies is reflected in the current literature. Besides this approach, interdisciplinary combination of therapies is a promising approach to the optimization of oncological therapy strategies. Local thermoablation in association with systemic or local chemotherapy, and surgical resection in association with thermoablation are interdisciplinary therapy concepts that expand the range of therapeutic options available. Against this backdrop, studies to evaluate interventional tumor therapies as part of interdisciplinary combination therapies are necessary.
