We developed nomograms to predict disease recurrence in patients with Ta, T1 transitional cell carcinoma of the bladder. Thirty-eight training hospitals participated in this retrospective multicenter study. Between 1998 and 2002, a total of 1,587 patients with newly diagnosed non-muscle invasive bladder cancer were enrolled in this study. Patients with prior histories of bladder cancer, non-tra...

UNLABELLED Except for smoking and certain occupational exposures, the etiology of bladder cancer is largely unknown. Several case reports have described familial aggregation of transitional cell carcinoma of the bladder. Although the majority of patients with bladder cancer do not have family history of transitional cell carcinoma of the urinary tract, the study of familial transitional cell ca...

OBJECTIVE To evaluate the prevalence of "high risk" human papillomavirus type 16 (HPV 16) in transitional cell carcinoma of the urinary bladder. MATERIALS AND METHODS The study included 10 biopsy specimens from male patients of transitional cell carcinoma of the urinary bladder for the detection of HPV DNA sequences. Specimens were collected from the Urology Clinic of the K.G. Medical College...

The morphological, biological, biochemical, and karyotypic characteristics of four human bladder transitional cell carcinoma lines, SW-780, SW-800, SW-1738, and SW-1710, were investigated. In tissue culture, each cell line presented a distinct phenotypic expression. All but line SW-1710 grew when transplanted in the nude mouse. Light and electron microscopic studies showed morphological charact...

Abstract Background Melanosis of the bladder is a rare condition characterized by multifocal, diffuse melanin pigmentation urothelial mucosa or lamina propria without any proliferation melanocytes. Less than 25 cases have been reported so far which only four patients had concurrent carcinoma. Case presentation We are reporting case melanosis in 58-year-old female associated with pTaG1 transitio...

Purpose: There is a need for improved subclassification of urothelial carcinoma (UC) at diagnosis. A major aim of this study was to search for novel genomic subgroups. Experimental design:We assessed 160 tumors for genome-wide copy number alterations andmutation in genes implicated inUC. These comprised all tumor grades and stages and included 49 high-grade stage T1
