Index tumor location affected early biochemical recurrence after radical prostatectomy in patients with negative surgical margin: a retrospective study.

Background: Index tumors are the most aggressive tumors of the prostate. However, their clinical significance remains unclear. This study aimed to assess the incidence of index tumor location according to the zonal origin and whether these locations affect the prognosis after radical prostatectomy in patients with negative surgical margins.

Prognostic risk stratification of patients with urothelial carcinoma of the bladder with recurrence after radical cystectomy.

Purpose: We identify clinicopathological variables predicting overall survival in patients with recurrent bladder urothelial carcinoma after radical cystectomy.

Materials And Methods: We retrospectively collected data on 114 patients treated with radical cystectomy for bladder urothelial carcinoma who subsequently had remote metastasis and/or local recurrence. The Kaplan-Meier method with the log rank test and multivariate Cox regression models were used to address overall survival after recurrence.

Advanced carcinoma of the prostatic urethra in a patient with marked response to chemotherapy, leading to preservation of the bladder.

We performed transurethral resection of the prostate (TUR-P) for a 66-year-old man with benign prostatic hyperplasia. Pathological examination diagnosed poorly differentiated urothelial carcinoma of the urethra with broad prostatic permeation. Random bladder biopsies showed no malignancy, but a second TUR-P revealed urothelial carcinoma in the prostate and bladder neck.
