The market for lutetium-177 is expected to grow significantly in the coming years. There are many products in the clinical pipeline that use lutetium-177 as radioactive substance, and we are seeing new, up-and-coming therapies. A promising agent is lutetium-177 PSMA, which acts on the prostate-specific membrane antigen and is used in the treatment of metastasised prostate cancer. In addition to prostate carcinomas, other cancers could be treated with the isotope lutetium-177 in the future. Prof. Hendrikse of Amsterdam UMC, VUmc location, foresees expanding possibilities for patient treatment despite some issues related to market availability.
