Selective internal radiation therapy (SIRT or radioembolisation) by intraarterial injection of radioactive yttrium-90 (90 Y)-loaded microspheres is increasingly used for the treatment of patients with liver metastases or primary liver cancer.

The high-dose beta-radiation penetrates an average of only 2.5 mm from the source so that its effects are limited to the site of delivery. However the off-target diversion of 90 Y microspheres to tissues other than the tumor may lead to complications.

The most prominent ones include: radiation gastritis and gastrointestinal (GI) ulcers, cholecystitis, radiation pneumonitis, and radioembolisation-induced liver disease (REILD).

Complications may occur despite careful pre-treatment planning and SIRT demands an expert multidisciplinary team (MDT) approach in order to provide comprehensive care for patients. This review provides recommendations to MDTs on the optimal medical processes in order to ensure the safe delivery of SIRT.

Based on the best available published evidence and expert opinion, we recommend the most appropriate strategies for the prevention, early diagnosis and management of potential radiation injury to the liver and to other organs.
