Theranostic Nanomedicine; A Next Generation Platform for Cancer Diagnosis and Therapy

In the recent years, theranostic nanomedicine based strategies have gained much attention in the field of oncology particularly, in the development of new generation cancer diagnostic and therapeutic tools. Today, various approaches have been developed for bioactive(s) targeting to predefined pathological sites, as well as for quantification of physiological processes and visualization. Significant attempts have been made to combine therapeutic and diagnostic properties in to a single effective nanomedicine formulation. This concept, coined as theranostics is smart nanosystem(s), able to diagnose, bioactive(s) delivery and monitoring of therapeutic response. By combining therapeutic functionalities with molecular imaging, theranostic based strategies may be beneficial in the selection of therapy, planning of treatment, monitoring of objective response and planning of follow-up therapy based on the specific molecular characteristics of a disease. In this manuscript, we reviewed the recent development of theranostic approaches, various nanosystems as theranostic agents and applications of theranostic in cancer therapeutics and diagnostics.
