Radionuclides can be labeled on biomolecules with specific binding ability. By binding with specific targets of tumors, particles such as α or β emitted by the radionuclides will specifically irradiate tumors and produce ionizing radiation effects, resulting in cell senescence and death within the irradiation range, achieving tumor treatment results, and this way has little impact on surrounding normal tissues. Lutetium-177 (177Lu) can emit γ rays for CT imaging, and can also emit β rays for tumor treatment, so 177Lu is now one of the radionuclides that can be used for integrated diagnosis and treatment. This review summarizes the clinical application of 177Lu in several solid tumors, in conjunction with currently published research.
