Sorafenib and Micro-therapy Guided by Primovist Enhanced MRI in Patients With Inoperable Liver Cancer

"A max.of 2 percutaneous RFA sessions is permitted per patient with a max.of 2 liver lesions treated in each RFA session. Randomization to sorafenib or placebo is performed after completion of RFA. Percutaneous RFA is to be performed according to the manufacturer's instructions and following as far as possible routine procedures of the participating hospital. Typically, RFA will be performed under conscious sedation, general anesthesia is permitted. After local anesthesia of the site of puncture, the applicator is positioned in the center of the lesion using ultrasound-, CT- or MR-guidance. The success of ablation is to be controlled directly after RFA using ultrasound, contrast-enhanced CT, or MR imaging. If for any reason RFA is deemed incomplete within the immediate follow-up (up to 2 weeks after the initial ablation), RFA is to be repeated once (in this case, the total (max.) number of RFA sessions will be three).~The study procedure guide will contain further instructions for RFA."

"One SIRT prescription consists of the pre-treatment assessment followed by one or 2 treatment sessions The aim of pre-treatment assessment is to ensure delivery of the microspheres to the target. Evaluation includes a determination of the arterial location and any consequent necessity for coil-embolization of the gastroduodenal artery, right gastric artery and any other accessory arteries to prevent inadvertent administration of microspheres into the gastrointestinal tract or pancreas. In addition, parasitic extrahepatic supply should be coil-embolized.~Patients in whom the shunt fraction indicates potential exposure to the lung to an absorbed radiation dose of more than 30 Gy should be excluded from treatment with SIR-Spheres. Patients who are randomized to receive SIRT but who are not regarded as eligible for SIRT after the pre-treatment assessment will be switched to the sorafenib only group within the palliative treatment arm."
