Prognostic value of radical cystoprostatectomy in men with bladder cancer infiltrating prostate versus co-existing prostate cancer: a research study.
Summary of "Prognostic value of radical cystoprostatectomy in men with bladder cancer infiltrating prostate versus co-existing prostate cancer: a research study."
The aim of the following study is to evaluate the advancement of incidentally diagnosed prostate cancer in specimen after cystoprostatectomies caused by muscle-invasive bladder cancer. Secondly we assessed the survival in patients after radical cystoprostatectomy whose postoperative specimen was characterized by the presence of co-existing prostate cancer or prostate infiltration by urothelial bladder cancer.
Between 1993 and 2009 a total of 320 patients with muscle-invasive bladder cancer underwent cystoprostatectomy. The first analyzed group consisted of 52 patients with bladder cancer infiltrating prostate, while the second group consisted of 21 patients with co-existing prostate cancer. In all patients cancer specific survival and progression were analyzed. Average follow up was 75.2 months (range: 0 - 181).
Cancer-specific survival was significantly shorter in group I (p=0.03). Neoplastic progression in patients from group I was observed in 42.2% of patients, while in patients from group II in 23.6% of patients (p=0.04). No statistical difference was observed in the percentage of positive lymph nodes between the groups (p=0.22). The median Gleason score in patients with co-existing prostate cancer was equal to 5. The stage of prostate cancer pT2/pT3 was equal to 20 (96%)/ 1 (4%) patients. 12 (57%) prostate cancers were clinically insignificant. Biochemical recurrence occurred in 2 (9%) patients.
1. Incidentally diagnosed prostate cancer in specimen after cystoprostatectomies is frequently clinically insignificant and characterized by low progression. 2. Patients with bladder cancer infiltrating prostate are characterized by higher percentage of progression and death in comparison with patients with co-existing prostate cancer.

Urinary Bladder Neoplasms
Tumors or cancer of the URINARY BLADDER.
A HERNIA-like condition in which the weakened pelvic muscles cause the URINARY BLADDER to drop from its normal position. Fallen urinary bladder is more common in females with the bladder dropping into the VAGINA and less common in males with the bladder dropping into the SCROTUM.
A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)
The univalent radical OH. Hydroxyl radical is a potent oxidizing agent.
Urinary Incontinence, Stress
Involuntary discharge of URINE as a result of physical activities that increase abdominal pressure on the URINARY BLADDER without detrusor contraction or overdistended bladder. The subtypes are classified by the degree of leakage, descent and opening of the bladder neck and URETHRA without bladder contraction, and sphincter deficiency.
In the management of muscle-invasive bladder cancer, prostate-sparing cystectomy represents a surgical alternative to radical cystoprostatectomy with equivalent oncological and improved functional res...
Cystoprostatectomy (CPT) is the gold standard surgical treatment for muscle invasive bladder cancer (MIBC). In certain cases, MIBC can invade the prostate gland and/or a prostate cancer (PCa) can be d...
Background: Radical cystoprostatectomy (RCP) remains the gold standard for the treatment of muscle-invasive bladder cancer. There are limited data regarding the clinical impact and detection of PSA fo...
Introduction: Hydronephrosis and BMI are analyzed together with established factors such as TNM stage and surgical margins in a multivariate modality to investigate their status as independent prognos...
Accepted prognostic factors for urothelial carcinomas of the bladder are tumor grade, T category, and in cases of muscle invasive carcinoma lymph node status. These morphological criteria correlate in...
This pilot study is designed to determine feasibility and safety of treatment with dasatinib administered orally once daily for 4 weeks duration prior to radical cystectomy for urothelial...
Complications after radical cystectomy for bladder cancer range from 30-40%, many of which are related to bowel function. Patients usually wait to eat until return of bowel function, alth...
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug and giving them after surgery may kill...

The measurement of circulating tumor cells is pursued in several cancers including breast and prostate cancer. The number of cells measured in these cancers has been shown to be prognosti...
