Summary:

Purpose: to analyze the expression of immunohistochemical markers in patients with prostate adenocarcinoma at high risk of progression before and after combined and combined treatment of patients with prostate specific antigen (PSA) level of blood below discriminatory. Material and methods. Examined patients (n = 80) with a diagnosis of “High-risk progression prostate cancer,” with clinical stage T3a, total score for Gleason scale from 8 to 10, the level of total PSA more than 20 ng / ml. Patients of the 1st group (n = 42) only combined surgical treatment in the scope of TUR and HIFU ablation the prostate; The 2nd group of patients (n = 38) additionally applied androgen deprivation in adjuvant mode. Results. Blood PSA, determined in patients after various methods of treatment is not always an objective indicator of its effectiveness. Immunohistochemical studies of tumor tissue for proliferative activity tumor cells, the activation of apoptosis in them, as well as the assessment of specific tumor markers and tumor suppressor genes showed that a decrease in the expression of these markers in patients with PSA values ​​of blood lower than discriminatory observed in all patients independently on the type of treatment. However, after treatment in the 1st group of patients, despite the achievement PSA level of nadir, there is a decrease in the expression of an intercellular adhesion marker E-cadherin, which indicates an increased risk of tumor metastasis, as well as increased expression of markers of the apoptosis inhibitor Bcl-2 and androgens, which indicates about the possibility of progression of tumor growth. Conclusion For a more accurate assessment therapeutic pathomorphism in patients with prostate cancer at high risk of progression, which HIFU ablation monotherapy was carried out, along with the determination of blood PSA level, it is necessary during the control biopsy of the prostate immunohistochemical studies of tumor tissue to determine the prognosis and risk of relapse.

Summary:

Objective: to assess the possibility of using markers of renal injury and carcinogenesis as additional criteria for the choice of the method of surgical treatment of RCC and to minimize the risk of development and progression of kidney injury. Material and Methods. 60 patients with morphologically confirmed RCC T1-3M0N0 operated on in the volume of open nephrectomy or laparoscopic nephrectomy or laparoscopic resection and the kidney were examined. Patients were divided into 3 groups: group 1: patients after nephrectomy performed for kidney cancer using traditional surgical technique, group 2: patients after laparoscopic nephrectomy and group 3: after laparoscopic resection of kidney tumor. Before surgical operation, on the 5-7 day and after 1 month, all patients were examined by concentrations of urinary excreted lipocalin 2 (NGAL), and serum concentrations of IL-18, MMP-9 and IGF-1. Renal function was estimated using the calculated GFR equation (CKD-EPI 2009) based on serum creatinine level. Immunohistochemical study of histological preparations of distant tumors on proliferation antibodies (Ki-67, PCNA), apoptosis (BAX, Bcl-2) was performed. Differences in clinical data and clinical variables were compared using Spearman rank correlations and t-test. Results. The studied indices of renal damage of IL-18, NGAL, MMP-9 and IGF-1 both in the early (5-7 days) and later (1 month) postoperative period showed a correlation between the surgical intervention method and the degree of tumor cell differentiation. Conclusion. The levels of biomolecular markers of renal damage (IL-18, NGAL, MMP-9 and IGF-1) correlate with the degree of differentiation in thetumoral cells and functional activity of the remaining renal parenchyma in the postoperative period, but also depend on the individual characteristics of the patient's body. A certain level of expression of MMP-9 and IL-18 with a small tumor size can be a guide to determine the indications for the choice of organ-preserving surgery in patients.

Summary:

The aim: to determine the complication's rate, based on a seven-year experience, after the stress urinary incontinence correction in women with different methods of setting suburethral polypropylene meshes. Material and Methods. The analysis of seven years of experience of surgical correction with different methods of setting suburethral meshes in 1260 women with stress urinary incontinence; obturator fixation the mesh inside-outside and outside-inside: supra-pubic fixation the mesh; non-trocar fixation the mesh type mini-sling was carried out. Results. The greatest frequency of complications were identified in the first two years of implementation the setting of suburethral meshes, after that the complication's rate decreased progressively and it was in the range 7-8% the last three years. The frequency of early operative complications at a different setting of suburethral meshes had no statistically significant differences, but there were more the statistically significant intraoperative and mesh-associated complications at suprapubic fixation. Conclusion. The study confirms that the installation of suburethral meshes by the method of suprapubic fixation of mesh is associated with a higher incidence of complications and should be performed only in the target group of patients who are not suitable for surgical correction in safer ways.

Summary:

Purpose: to improve the results of treatment of the obstructive complications (an urethra stenosis, a bladder neck sclerosis) caused by application of the high-intensity focused ultrasonic ablation (HIFU) concerning treatment of the localized prostate cancer. Material and Methods. An object of the research included 41 patients, with the infravesical obstruction (IVO) which has arisen in the postoperative period to which elimination the holmium laser is used. Results. The bladder neck was the most frequent place of obstruction. Average time before emergence of the first episode of IVO: 8.2±1.3 months. Distinctions on time before development of an episode of IVO depending on the fact of carrying out TURP before HIFU not confirmed (p=0.440). More advanced age for a moment HIFU-ablation has been associated with much higher frequency of IVO (p=0.021). Considerably smaller frequency repeated was observed by IVO at a larger ratio transurethral resection to the initial volume of a prostate (p=0.031). Duration of a laser endoscopic ure-throtomy was 27 [10-70] minutes, serious perioperative or postoperative complications were not determined. Average term before removal of a catheter of Foley: 3 [1-5] days, hospitalization duration included 4 [3-6] days. After treatment considerable improvement on indicators of the maximum speed of a stream of urine (Qmax) and volume of residual urine was observed. The total score according to the questionnaires of IPSS and QoL has considerably improved, significant changes on symptoms of accumulation are noted. After the first holmium laser urethrotomy of 80.4% of patients have noted satisfactory results without recurrence of IVO; 19.6% of patients were required a repeated laser endoscopic urethrotomy. Recurrence term after the first laser urethrotomy is on average equal to 2.5 months. Conclusion. The endoscopic urethrotomy by means of the holmium laser is safe, effective and minimum invasive type of treatment of a stenosis of a neck of the bladder / urethra after ablative cancer therapy of prostate. The advantages are the minimum of traumas of surrounding tissues and preservation of the mechanism of deduction of urine.

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.
