Sharpening the Blade of Precision Theranostics

Abstract

While theranostics is a new term for long-standing principles in nuclear medicine, recent advances have facilitated more personalized healthcare and precision medicine. Despite the widespread enthusiasm for theranostics and well established and standardized procedures, there are a number of opportunities to enhance practice and sharpen the blade of precision theranostics. A clear understanding of the requisites of an authentic theranostic pair reveals limitations in current approaches. Indeed, standardized dosing regimes based on activity dose as opposed to absorbed dose highlight the potential enhancements to outcomes and precision medicine that predictive dosimetry could bring. Such advances increase the demand for closer matching of biological and chemical properties of theranostic pairs. In turn, the need for more authentic or true theranostic pairs is revealed. While theranostics has provided a revolutionary toolkit for cancer management, advances in instrumentation, radiochemistry or clinical domains requires similar advances in the remaining domains. This discussion explores key considerations for an evolving theranostics landscape, recognising current best practice may fall short of precision medicine over coming years.
