Molecular–clinical characteristics and treatment outcomes in 163 metastatic colorectal neuroendocrine carcinomas with a comparison to colorectal adenocarcinomas

International Journal of Cancer, Volume 158, Issue 12, Page 3217-3231, 15 June 2026.
What's new? Colorectal neuroendocrine carcinoma (CR‐NEC) is a rare digestive neuroendocrine neoplasm that frequently exhibits an adenocarcinoma component. Nonetheless, the underlying biology of CR‐NEC remains poorly understood. This study examined molecular and clinical features and palliative chemotherapy outcomes of metastatic CR‐NEC, with comparison

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

Journal 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 ...

Structural Eigenmodes of the Brain to Improve the Source Localization of EEG: Application to Epileptiform Activity

Advanced Science, Volume 13, Issue 31, 4 June 2026.
Geometry and connectivity are complementary structures, which have demonstrated their ability to represent the brain's functional activity. This study evaluates geometric and connectome eigenmodes as biologically informed constraints for EEG source localization.

1H MR‐based detection of human plasma metabolic alterations in clear cell renal cell carcinoma

BJUI Compass, Volume 7, Issue 6, June 2026.
Abstract Objectives This study aimed to evaluate the potential of plasma‐based proton magnetic resonance spectroscopy (1H‐MRS) for non‐invasive discrimination between clear cell renal cell carcinoma (ccRCC), benign renal masses (angiomyolipoma and oncocytoma) and healthy controls by identifying disease‐specific metabolic signatures.

Development of a Risk Prediction Model for Bone Metastasis in Lung Adenocarcinoma With a T1 Primary Tumor Based on Intratumoral and Peritumoral Radiomics

Cancer Medicine, Volume 15, Issue 6, June 2026.
ABSTRACT Purpose Bone metastasis significantly affects the prognosis of lung adenocarcinoma (LUAD) patients. This study aims to construct and validate a risk prediction model for bone metastasis in LUAD with a T1 primary tumor based on intratumoral and peritumoral radiomics features.
