The American Brachytherapy Society Consensus Statement for Permanent Implant Brachytherapy Using Yttrium-90 Microsphere Radioembolization for Liver Tumors.
Brachytherapy(2022)
Abstract
PURPOSE: To develop a multidisciplinary consensus for high quality multidisciplinary imple-mentation of brachytherapy using Yttrium-90 ( 90 Y) microspheres transarterial radioembolization ( 90 Y TARE) for primary and metastatic cancers in the liver.METHODS AND MATERIALS: Members of the American Brachytherapy Society (ABS) and colleagues with multidisciplinary expertise in liver tumor therapy formulated guidelines for 90 Y TARE for unresectable primary liver malignancies and unresectable metastatic cancer to the liver. The consensus is provided on the most recent literature and clinical experience.RESULTS: The ABS strongly recommends the use of 90 Y microsphere brachytherapy for the definitive/palliative treatment of unresectable liver cancer when recommended by the multidisci-plinary team. A quality management program must be implemented at the start of 90 Y TARE program development and follow-up data should be tracked for efficacy and toxicity. Patient -specific dosimetry optimized for treatment intent is recommended when conducting 90 Y TARE. Implementation in patients on systemic therapy should account for factors that may enhance treat-ment related toxicity without delaying treatment inappropriately. Further management and salvage therapy options including retreatment with 90 Y TARE should be carefully considered.CONCLUSIONS: ABS consensus for implementing a safe 90 Y TARE program for liver cancer in the multidisciplinary setting is presented. It builds on previous guidelines to include recommen-dations for appropriate implementation based on current literature and practices in experienced centers. Practitioners and cooperative groups are encouraged to use this document as a guide to formulate their clinical practices and to adopt the most recent dose reporting policies that are criti-cal for a unified outcome analysis of future effectiveness studies.(c) 2022 American Brachytherapy Society.
