By situating PSMA within this broader biomarker landscape, we outline opportunities for theranostic integration, including predictive models, combination therapies and expansion into non-prostate malignancies. Understanding the biology of PSMA in conjunction with novel biomarkers provides a framework for optimising theranostic applications and advancing personalised cancer care.

In 2018, the Food and Drug Administration (FDA) approved lutetium-177 (177Lu) DOTATATE (LUTATHERA, Advanced Accelerator Applications [Novartis]) for the treatment of somatostatin receptor positive gastroenteropancreatic neuroendocrine tumors (GEP-NETs)...Less than 5 years later, in March 2022, 177Lu vipivotide tetraxetan (PLUVICTO, Advanced Accelerator Applications) received FDA approval for the treatment of prostatespecific membrane antigen-positive castration-resistant metastatic prostate cancer...As more radiotheranostic agents and applications get adopted in clinical practice, interventional radiologists are likely to get exposed to this field in a way or another. In this article, we discuss the fundamentals of radiotheranostic therapy and explore the expanding role interventional radiology (IR) is expected to play as an essential partner in modern oncology practice.

Following PRRT, analysis of [68Ga]Ga-FAPI-04 PET/CT in well-differentiated NET is important to avoid misinterpretation. Benign fibrosis following treatment may show FAPI uptake as a possible source of false-positive findings on [68Ga]Ga-FAPI-04 PET/CT in the evaluation of NET.

Given the lack of significant effects on direct DNA repair or transcriptomic responses, our findings suggest that HSP90 inhibition radiosensitizes NET cells by inducing a pleiotropic effect on multiple stress-related pathways at the protein level, rather than solely through disruption of DNA damage response mechanisms. This effect is likely driven by loss of HSP90 function and subsequent cumulated unfolded protein and proteotoxic stress.

Baseline assessment reflects the patient's reserves and their post-PRRT state. Further, women are more prone to BM-related toxicity from PRRT. These insights can help optimize treatment strategies and improve patient outcomes in this population.
