Microsatellite Instability in Urothelial Carcinoma of the Upper Urinary Tract

Journal of Urology, 2003
Transitional cell carcinoma (TCC) of the upper urinary tract (TCC-UUT) may develop with high frequency in patients with hereditary nonpolyposis colorectal cancer syndrome. Tumors in patients with this syndrome show genomic lesions in DNA mismatch repair genes that are detectable as microsatellite instability (MSI). Because little is known about genetic

Upper urinary tract urothelial carcinomas – our experience

Perspectives in Surgery, 2020
Introduction: Urothelial carcinoma is the second most common urological malignancy. Around 5–10% of tumors are found in the upper urinary tract, while almost 90–95% are in the bladder. Methods: Patients of our department diagnosed with upper urinary tract urothelial carcinoma (UTUC) during the period 2014–2018 were included.

Nested Subtype of Urothelial Carcinoma in the Upper Urinary Tract

American Journal of Surgical Pathology, 2022
Nested subtype of urothelial carcinoma (NVUC) of the upper urinary tract is rare. While this subtype has an aggressive behavior in the urinary bladder, little is known about this subtype in the renal pelvis and ureter. In addition, due to NVUC’s bland morphology and resemblance to von Brunn nests proliferation, which can be florid in the renal pelvis ...

Clinical significance of micropapillary urothelial carcinoma of the upper urinary tract

Journal of Clinical Pathology, 2013
Background The aim of this study was to improve understanding of the characteristics of micropapillary urothelial carcinoma (MPUC) in the renal pelvis and ureter, and to compare oncological outcomes between MPUC and non-MPUC.

Molecular and histological markers in urothelial carcinomas of the upper urinary tract

BJU International, 2008
Urothelial cell carcinomas (UCCs) are one of the most common types of malignancies. Recently, different mechanisms of carcinogenesis, as well as discrepancies in the natural history of urothelial cancers of the bladder and of the upper urinary tract (UUT), have been identified.

Upper Urinary Tract Urothelial Carcinoma Pathology

2014
Urothelial carcinomas of the upper tract are malignant neoplasms arising from the pelvicalyceal and ureteral mucosal lining and sharing the same pathologic spectrum and overall classification as urothelial neoplasms of the urinary bladder. However, upper tract urothelial carcinomas are more frequently high grade and high stage and show frequent variant

[Upper urinary tract urothelial cell carcinoma].

Der Urologe. Ausg. A, 2020
Upper urinary tract urothelial cell carcinoma (UTUC) is a rare entity. The incidence in Germany is approximately 2/100,000 with a ratio between women and men of 1:2.5. Most clinical signs are nonspecific, which is why early diagnosis is rarely successful.

GATA3 immunohistochemistry in urothelial carcinoma of the upper urinary tract as a urothelial marker and a prognosticator

Human Pathology, 2017
Immunohistochemistry of a transcription factor, GATA3, has been widely used as a promising urothelial marker in diagnostic surgical pathology practice. However, the expression status of GATA3 in upper urinary tract urothelial carcinomas (UUTUCs) and its prognostic significance have not been fully investigated. We immunohistochemically stained for GATA3

Considerations: Imaging in Upper Urinary Tract Urothelial Carcinoma

2008
According to the surface of both the collecting systems and the ureters in relationship to the urinary bladder, urothelial carcinoma of the upper urinary tract occurs in about 5% of all transitional cell carcinoma. Upper urinary tract tumors are rarely detected incidentally or by screening. Usually, patients present with flank pain, recurrent hematuria,
