Incidence, risk factors, and mortality of acute kidney injury in patients receiving immune checkpoint inhibitors: analysis by acute kidney injury subtype

Background: Acute kidney injury (AKI) is a common complication in patients receiving immune checkpoint inhibitor (ICI) therapy. It can result from conventional causes or immune-mediated mechanisms. This study aimed to determine the incidence, risk factors, and clinical outcomes o...

Lobular carcinoma as a spectrum: resolving the gray zone between morphology, E-cadherin, and CDH1

Invasive lobular carcinoma (ILC) is characterized by E-cadherin loss resulting from CDH1 inactivation, but discordance among morphology, immunohistochemistry (IHC), and molecular findings can complicate diagnosis. We integrated histology, IHC, DNA sequencing, and whole-transcript...

Integrative Genomic Analysis Reveals Molecular and Clinical Disparities between Bladder and Upper Tract Urothelial Carcinoma in K-MASTER Program

Purpose: The clinical outcome of urothelial carcinoma presents significant variability, reflecting its molecular composition, epidemiologic attributes, and primary site of origin. Despite histological similarities, upper tract urothelial carcinoma (UTUC) and bladder urothelial ca...
