Our exploratory analysis provides preliminary results showing that imaging indices of inter- and intra-tumor heterogeneity from pretreatment PET/CT images may potentially predict treatment efficacy in NET patients undergoing [177Lu]Lu-DOTA-TATE therapy. However, prospective evaluation in a larger cohort is needed to further assess whether a comprehensive characterization of tumor heterogeneity within a patient can help guide treatment decisions.
Regrowth of the tumor post-[177Lu]Lu-PSMA-617 administration creates Ki67+/PSMA+ areas that have no radioactivity uptake and need additional therapy fractions. The identical intratumoral distribution of [177Lu]Lu-PSMA-617 and PSMA-targeted PET-tracers indicate that these will reveal the areas inside the tumor targeted by RPT at least at 1 h p.i.
The U.S. Food and Drug Administration approval of 177Lu-PSMA-617 marked a substantial advancement in the treatment paradigm of metastatic castration-resistant prostate cancer, based on the VISION trial that showed improved overall survival and quality of life compared with those for standard care...This review underscores the role of PSMA radioligand therapy in the evolving landscape of prostate cancer treatment and its promise for improving patient outcomes.
Peptide receptor radionuclide therapy (PRRT) using [177Lu-DOTA0,Tyr3]octreotate (177Lu-DOTATATE) represents an established treatment modality for somatostatin receptor-positive, locally advanced or metastatic gastroenteropancreatic neuroendocrine tumours (GEP NET) of grade 1 or 2...The results of these studies are likely to help address existing knowledge gaps in the coming years. This review describes the clinical practice, recent developments and future treatment options of PRRT in patients with grade 1 and 2 GEP NET.
The NETseq ensemble classifier identified PRRT-naïve GEP-NETs with high accuracy (≥92%) and demonstrated a potential role in early treatment response monitoring in the PRRT setting. This blood-based, non-invasive, multi-analyte molecular method could be developed as a valuable adjunct to conventional methods in the detection and treatment response assessment in NET patients.
Potential high-risk factors in order to treat effectively and prevent these toxicities in NET patients are presented including the management strategy. This review also discusses novel insights, perspectives, and recent advancements in predicting, preventing, and managing toxicity associated with PRRT, while offering prospective future research directions to minimize clinical toxicity and maximize the therapeutic benefits of PRRT as a treatment strategy for NET patients.

The tumor AD that was reported during treatment with 177Lu-SSTR-RT in refractory meningioma patients is generally low. Harmonization of the methodology for dosimetry calculations is needed to compare the different reported values and optimize treatment at the individual level.

Careful patient selection, including consideration of the prognostic factors ECOG, baseline CEA, and KRAS status, sets outcome expectations in patients with colorectal liver metastases suitable for TARE/Chemo as second-line treatment (Trial Registry Number: NCT01483027).
