Advances and future directions in radiopharmaceutical delivery for cancer treatment.

Abstract

Introduction: Targeted radiopharmaceutical therapies (RPTs) have emerged as a promising approach for the precise treatment of various cancers. Delivering ionizing radiation directly to cancer cells while sparing surrounding healthy tissue, radiopharmaceuticals offer enhanced efficacy and reduced toxicity compared to conventional external beam radiation therapy (i.e. photons and electrons).

Areas covered: In the current era of personalized cancer care, the appropriate choice of RPTs for a clinical condition and the specific patient's care needs to be better understood. Several available RPT agents with their respective clinical applicability along with rapidly ongoing research in this field have now given RPTs the ability to lend themselves to a personalized medicine focus. This review provides an overview of recent advancements in RPT, including nuclide selection and development, molecular targeting strategies, radiopharmaceutical development, and clinical applications.

Expert opinion: We discuss the underlying principles, challenges, and opportunities for future development. Furthermore, we explore emerging technologies and future directions in the field, highlighting the potential impact on personalized cancer care.
