Impact of administered amount of peptide on tumor dosimetry at the first cycle of peptide receptor radionuclide therapy (PRRT) in relation to total tumor somatostatin receptor expression

open access: yesEJNMMI Research, 2023
Background The accumulation of 177Lu-DOTATATE might be influenced by the amount of administered peptide in relation to the tumor somatostatin receptor expression.

Design and validation of a deep learning GAN for predicting 177Lu dose voxel kernels using GATE/GEANT4 Monte Carlo and IDAC‐Dose 2.1 in phantom dosimetry

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 6, June 2026.
Abstract Background The rapid evolution of deep learning (DL), particularly the emergence of generative adversarial networks (GANs) has demonstrated strong potential for generating high‐resolution, voxel‐level dosimetric data. However, GAN‐based approaches have not yet been broadly applied to the generation of tissue‐specific dose voxel kernels (DVKs ...

GPCRs in CAR‐T Cell Immunotherapy: Expanding the Target Landscape and Enhancing Therapeutic Efficacy

open access: yesAdvanced Science, Volume 13, Issue 35, 24 June 2026.
Chimeric antigen receptor T cell therapy faces dual challenges of target scarcity and an immunosuppressive microenvironment in solid tumors. This review highlights how G protein‐coupled receptors can serve as both novel targets to expand the therapeutic scope and functional modules to enhance CAR‐T cell efficacy.

LONG-TERM EFFECT OF 177LU-DOTATATE ON SEVERE AND REFRACTORY HYPOGLYCEMIA ASSOCIATED WITH MALIGNANT INSULINOMA.

open access: yes, 2019
Malignant insulinoma is an extremely uncommon tumor that is usually accompanied by severe hypoglycemia that is difficult to manage. At this time, the long-term effect of 177Lu-DOTATATE (lutetium [Lu-177]-DOTA-Tyr3-octreotate) on this tumor is not well ...

Neuroendocrine tumours through an epigenetic lens: Emerging insights for diagnosis and treatment

open access: yesJournal of Neuroendocrinology, Volume 38, Issue 6, June 2026.
Abstract Neuroendocrine tumours (NETs) are well‐differentiated epithelial neuroendocrine neoplasms that frequently develop in the small intestine, pancreas, and lungs. NETs originate from neuroendocrine cells specialized in hormone secretion implicated in a number of physiological processes.

A Biochemically “Silent” Aortocaval Paraganglioma in a 19‐Year‐Old Female Causing Intraoperative Hypertensive Crisis: A Rare Case Report

open access: yesClinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT Paragangliomas may appear biochemically silent, yet still behave as functional tumors with severe intraoperative consequences. Normal preoperative catecholamine screening does not exclude the risk of hypertensive crisis during surgery.
