Renal cell carcinoma (RCC) occurring in the setting of end-stage renal disease (ESRD) shows unique clinicopathological characteristics. The two most frequent types of ESRD-associated RCC are acquired cystic kidney disease-associated renal cell carcinoma (ACKD-RCC) and clear-cell papillary renal cell carcinoma (ccpRCC). Other types of RCC also occur in ESRD, albeit with different frequencies from the non-ESRD general population. Read More

The incidence of cancer is higher in patients with end-stage kidney disease (ESKD) than among the general population. Despite this, screening for cancer is generally not cost-effective and may worsen quality of life in these patients. This is due to high mortality rates (patients are not living long enough to reap the benefits of screening), the inaccuracy of cancer screening tests, and the increased risks associated with therapy in patients with ESKD.

To investigate the pathogenesis of a congenital form of hepatic fibrosis, human hepatic organoids were engineered to express the most common causative mutation for Autosomal Recessive Polycystic Kidney Disease (ARPKD). Here we show that these hepatic organoids develop the key features of ARPKD liver pathology (abnormal bile ducts and fibrosis) in only 21 days. The ARPKD mutation increases collagen abundance and thick collagen fiber production in hepatic organoids, which mirrors ARPKD liver tissue pathology. Read More

Autosomal recessive polycystic kidney disease (ARPKD) is a severe disease of early childhood that is clinically characterized by fibrocystic changes of the kidneys and the liver. The main cause of ARPKD are variants in the PKHD1 gene encoding the large transmembrane protein fibrocystin. The mechanisms underlying the observed clinical heterogeneity in ARPKD remain incompletely understood, partly due to the fact that genotype-phenotype correlations have been limited to the association of biallelic null variants in PKHD1 with the most severe phenotypes.

A 48-year-old man with histories of IgA nephropathy for 33 years, hemodialysis for 29 years, and a kidney transplant from a deceased donor 5 years ago was admitted to our institute complaining of high fever and back pain. Although repeated follow-up of computed tomography failed to detect any de novo issues, he was eventually diagnosed as a renal cell carcinoma with multiple metastases, developing from his native-acquired cystic disease kidney with multiple cysts using a positron emission tomography. We should be cautious of de novo renal cell carcinoma in kidney transplantation recipients, and careful follow-up might be helpful to detect it. Read More

The Genitourinary Pathology Society (GUPS) reviewed recent advances in renal neoplasia, particularly post-2016 World Health Organization (WHO) classification, to provide an update on existing entities, including diagnostic criteria, molecular correlates, and updated nomenclature. Key prognostic features for clear cell renal cell carcinoma (RCC) remain WHO/ISUP grade, AJCC/pTNM stage, coagulative necrosis, and rhabdoid and sarcomatoid differentiation. Accrual of subclonal genetic alterations in clear cell RCC including SETD2, PBRM1, BAP1, loss of chromosome 14q and 9p are associated with variable prognosis, patterns of metastasis, and vulnerability to therapies.

The architecture of renal glomeruli is acquired through intricate and still poorly understood developmental steps. In our study we identify a crucial glomerular morphogenetic event in nephrogenesis that drives the remodeling/separation of the prospective vascular pole (the future entrance of the glomerular arterioles) and the urinary pole (the tubular outflow). We demonstrate that this remodeling is genetically programmed. Read More
