Primary high-grade urothelial carcinoma of prostate with prostatic hyperplasia: a rare case report and review of the literature.

Background: Primary urothelial carcinoma in the prostate (UCP) is extremely rare and occurs most frequently in the bladder. There are only dozens of primary cases reported in the literature. Here, we describe a rare case of primary UCP and review the literature.

Development and validation a model for predicting overall survival of bladder cancer with lung metastasis: a population-based study.

Background: Although the number of patients with bladder cancer and lung metastasis is increasing there is no accurate model for predicting survival in these patients.

Methods: Patients enrolled in the Surveillance, Epidemiology, and End Results database between 2010 and 2015 were selected for the study. Univariate and multivariate Cox regression were used to determine independent prognostic factors, followed by development of a nomogram based on the multivariate Cox regression models.

[Expression of estrogen receptor alpha in the testis of infertile men with spermatogenic arrest].

Objective: To explore the association of spermatogenic arrest with the expression of estrogen receptor alpha (ERalpha) in human testes.

Methods: We examined the testicular biopsy specimens of 120 infertile men by HE staining, detected the expression of ERalpha in the specimens of those with spermatogenic arrest by the two-step immunohistochemical method, and compared the results with those of 10 healthy men.

Results: Of the 120 specimens from the infertile men, 31 (25.
