Summary:

The review analyzes the recent publications of the results of the use of molecular genetic markers of bladder cancer (RMP) in clinical practice. The prospects of application of a series of molecules determined in tumor tissue, serum, urine in the diagnosis of RMP are presented. One ofthe most promising areas of finding a marker forthe diagnosis and control of treatment of RMP in recent years are the study ofthe proteomic composition of urine.

The prospects for application of biomarker "vascular endothelial growth factor" in predicting the treatment outcomes of bladder cancer

Summary:

Purpose: assessment of the diagnostic value of Vascular Endothelial Growth Factor (VEGF) in predicting the outcome treatment of patients with muscle-invasive bladder cancer. Material and Methods. The study involved 264 people: 204 patients with RMP; 60 people aged 21 to 60 years were the comparison group. Patients with RMP are divided into stages of the disease. With non-muscle-invasive ВС (NIRMP) under TA-1NxMo there were 75 patients. Out of 129 patients with muscle-invasive ВС (MIRE) within the body (pT2aN0M0-T2bN0M0) was diagnosed in 69 of people. In 60 patients, the tumor sprouted paravesical tissue and surrounding organs (rt3a-bn0m0-41; pT36N1M0-11; pT4N1M0-5; T4N1M1-3); 19 patients had metastases to the iliac lymph nodes are installed only after the operation. Metastases were found in three patients out of 19 in addition to the lymphonoduses in the lungs. Tumors had the following gradations: G1-97; G2-37; G3-58. All patients NMIN (n=75) completed a TUR of the bladder wall with the tumor. MERE patients underwent radical cystectomy (n=117), open resection of the bladder (n=12), palliative surgery (n=3). The period of follow-up after surgical treatment was 3.5±0.5years. Quantitative determination of VEGF in blood serum was performed by solid-phase ELISA. Results. Despite the fact that the increase in VEGF level of blood serum in groups of patients with NIMRE and MIRE has significant differences both before and in the postoperative period, it is associated with the aggressiveness of tumor growth, development of metastases and recurrences of the disease. Conclusion. The increase in the content of VEGF serum suitable for use as an indicator: the risk of relapse within the first year after TUR in patients NMIN; development of relapses and metastases in pre and postoperative periods in MERE patients.

Magnetic resonance diffusion-weighted whole-body imaging (DWIBS) in bladder cancer diagnostics

Year: 2011, volume 7 Issue: №4 Pages: 941-946
Heading: Urology Article type: Original article
Authors: Popkov V.M., Chekhonatskaya M.L., Zuev V.V., Ponukalin A.N., Nikolsky Y.E.
Organization: Saratov State Medical University
Summary:

The purpose of the article is to identify the most characteristic and significant changes in indicators in patients with bladder cancer during diffusion-weighted whole-body imaging (DWIBS). Materials: From September 2009 till 2011 98 patients have been examined (61 (62,24%) with morphologically verified bladder cancer and 37 (37,76%) with cystitis. Results: The study has revealed that the sensitivity of DWIBS-study in detecting bladder cancer is 98,36%, specificity of 10,81 %, the efficacy of 65,38%. Conclusions: DWIBS is an informative noninvasive method for screening diagnostics of bladder cancer, to identify suspicious areas on regional, and distant metastases

Application of automated morphometric method of estimation of expression of immunohistochemical markers in diagnostics of prostate and bladder cancer

Year: 2010, volume 6 Issue: №4 Pages: 845-849

Organization: Saratov State Medical University, Institute of Biochemistry and Physiology of Plants and Microorganisms of Russian Academy of Sciences
Summary:

The diagnostic significance of molecular markers was evaluated by immunohistochemical research of surgical and biopsy material of 106 patients with diseases of bladder and 57 patients with diseases of prostate. They received treatment at Scientific Research Institute of Fundamental and Clinical Uronephrology with monoclonal antibodies: Ki-67, PCNA, p63 (markers of proliferative activity), p53 (suppressor of tumor growth), Bcl-2, Bax (markers of apoptosis), EGFR (receptor of epidermal growth factors), PSA, PSMA, AMACR (prostate-specific antigens) and cytokeratin profile. The morphometric research was conducted on the basis of automated analysis system of digital images Ariol SL50 (Genetix)
