AI Article Synopsis

  • The goal in cancer radiotherapy is to deliver radiation precisely to tumors while minimizing damage to healthy tissue.
  • Injectable systemic radionuclide therapies show potential in achieving this, even for small metastases and single cancer cells.
  • This review focuses on the different methods for determining the location of radiopharmaceuticals in cells and their pros and cons, especially in relation to dosimetry challenges for certain radionuclides.

Article Abstract

In oncology, the holy grail of radiotherapy is specific radiation dose deposition in tumours with minimal healthy tissue toxicity. If used appropriately, injectable, systemic radionuclide therapies could meet these criteria, even for treatment of micrometastases and single circulating tumour cells. The clinical use of α and β particle-emitting molecular radionuclide therapies is rising, however clinical translation of Auger electron-emitting radionuclides is hampered by uncertainty around their exact subcellular localisation, which in turn affects the accuracy of dosimetry. This review aims to discuss and compare the advantages and disadvantages of various subcellular localisation methods available to localise radiopharmaceuticals and radionuclides for in vitro investigations.

Kisspeptin (KISS1) and its cognate receptor (KISS1R) are implicated in the progression of various cancers. A gallium-68 labelled kisspeptin-10 (KP10), the minimal biologically active structure, has potential as a pan-tumour radiopharmaceutical for the detection of cancers. Furthermore, a lutetium-177 labelled KP10 could find therapeutic application in treating oncological diseases.

We report the 99mTc-MDP bone scan of a 44-year-old man with a history of lung adenocarcinoma and recent multiple joint pain after completing pembrolizumab immunotherapy treatment. This interesting image of symmetric uptakes around bilateral joints throughout the skeleton resembles the ball sensors on a motion capture suit. Hence, we recommend naming this distinctive imaging appearance as the "motion capture suit" sign.
