Immunohistochemistry vs Molecular Breast Cancer Subtyping Among African Populations

Importance Breast cancer subtyping based on immunohistochemistry (IHC) guides systemic therapy where gene expression profiling assays are unavailable, yet its validity against molecular reference standards remains poorly characterized in African populations, where laboratory infr...

Metrology, Standards, and Mission: Synopsis of the 2026 Annual Meeting of the Council on Ionizing Radiation Measurements and Standards (CIRMS)

The Council on Ionizing Radiation Measurements and Standards (CIRMS) is an independent, non-profit council composed of experts from academia, government, and industry across all areas of ionizing radiation science and technology, providing leadership, focus, and coordinated actio...

What Is Pediatric Melanoma? Clinical and Genomic Features and the Role of Next‐Generation Sequencing in Tumor Classification

Pediatric melanoma is rare and often poses diagnostic challenges because benign and malignant melanocytic tumors in children can share overlapping clinicopathologic features. Epidemiologic and genomic studies have provided important insights into the etiology of pediatric melanoc...

Per- and polyfluoroalkyl substances levels other than PFOS, PFOA, or PFHxS and liver cancer risk: a nested case-control analysis

Abstract Epidemiologic studies of PFAS and liver cancer risk have produced conflicting results with no strong or clear associations for pre-diagnostic perfluorooctanesulfonate (PFOS), perfluorooctanoate (PFOA), and perfluorohexanesulfonate (PFHxS). We now report analyses of nine...

Integrative multiomic analysis identifies transcription factors and target proteins in renal cell carcinoma

Abstract Renal cell carcinoma risk is partly shaped by germline genetic variants that often reside in regulatory regions. However, the transcription factors (TFs) and downstream proteins via which they shape RCC susceptibility remain incompletely characterized. Here we show that...
