From the Literature

Discussions with leaders
Leading in Urology and Pioneering in Social Media Outreach: Ken Herrmann, MD, MBA, and Michael Hofman, MBBS, FRACP, talk with Declan Murphy, FRACS, FRCS, about his career in genitourinary oncology and widely influential outreach activities in social media

The State of the Art
FAPI PET/CT in nonmalignant diseases: Schmidkonz and colleagues offer a comprehensive review of fibroblast-activation protein inhibitor imaging in nonmalignant diseases to clarify current and potential roles of this class of molecules in nuclear medicine

Continuing Education
FDA approval for theranostic agents: Perera and Morris present an educational overview of regulatory approval for novel radiopharmaceutical agents, including the importance of trial design for agents targeting prostate cancer and regulatory experience with 223Ra and 177Lu-PSMA-617

Focus on Molecular Imaging
Nanoparticle diagnostics and theranostics: Pallares and colleagues provide an overview of nanoparticle-based imaging agents in the clinic and discuss preclinical progress and translational avenues for use in diagnostic and theranostic applications

Histopathologic validation of 18F-rhPSMA PET: Kroenke and colleagues investigate the accuracy and predictive value of 2 PSMA-targeting radiopharmaceuticals in assessment of lymph node metastases as validated by histopathology

PSMA PET/CT for therapy assessment: Denis and colleagues use recent European recommendations to compare response assessment to a novel hormonal agent for metastatic castration-resistant prostate cancer between PSMA PET/CT and conventional imaging

Initial 68Ga-PSMA-11 PET and outcomes: Moradi and colleagues examine the prognostic value of 68Ga-PSMA-11 uptake in the primary lesion and presence of metastatic disease on PET in newly diagnosed prostate cancer before initial therapy

68Ga-RM2 PET in primary prostate cancer: Duan and colleagues compare preoperative 68Ga- RM2 PET, targeting gastrin-releasing peptide receptors, with postsurgery histopathology in patients with newly diagnosed intermediate- or high-risk prostate cancer

Setting up a theranostics center: Herrmann and members of a joint European Association of Nuclear Medicine, SNMMI, and International Atomic Energy Agency advisory group provide an enabling guide for radiopharmaceutical stakeholders interested in establishing dedicated theranostics centers

Repetitive 68Ga-FAPI PET acquisition: Glatting and colleagues report on the diagnostic value of repetitive early PET imaging with 68Ga-FAPI-02, 68Ga-FAPI-46, and 68Ga-FAPI-74 for malignant, inflammatory/reactive, and degenerative lesions and describe implications for future 68Ga-FAPI imaging

FAP ligand with prolonged tumor uptake: Galbiati and colleagues detail the development and in vivo characterization of BiOncoFAP, a new dimeric fibroblast-activation protein–binding motif with extended tumor residence time and favorable tumor-to-organ ratios

Featured Article of the Month
α-Particle and immunocytokine therapy: Minnix and colleagues investigate tumor reduction and survival outcomes with low-dose targeted α-therapy followed by a 4-dose immunocytokine regimen in mouse breast and colon cancer tumor models

PET/CT for SiNET staging: Ouvrard and colleagues compare the respective values of 68Ga-DOTATOC and 18F-DOPA PET/CT for initial staging or presurgical work-up of patients with small-intestine neuroendocrine tumors

First-in-humans tissue factor PET: Loft and colleagues report on PET imaging with an 18F-radiolabeled active-site inhibited version of the tissue factor natural ligand coagulation factor VII and describe its potential as a diagnostic companion for tissue factor–targeted therapies

HDL PET and esophageal cancer: Zheng and colleagues use a multimodal imaging approach to assess tumor uptake of exogenously administered, 89Zr-labeled high-density lipoprotein nanoparticles in patients with esophageal cancer

PET/CT and head and neck cancer staging: Subramaniam and colleagues look at multicenter interobserver agreement and accuracy in 18F-FDG PET/CT imaging for staging of clinical N0 neck in head and neck cancer

166Ho radioembolization in HCC: Reinders and colleagues establish the toxicity profile of 166Ho radioembolization in patients with measurable, liver-dominant hepatocellular carcinoma and no or very limited curative treatment options

PET and GI graft-vs.-host disease: Cherk and colleagues explore the diagnostic utility of 18F-FDG PET/CT in noninvasive assessment of patients with clinically suspected acute graft-versus-host disease of the gastrointestinal tract associated with allogeneic hemopoietic stem cell transplantation

Featured Clinical Investigation Article
