Filter by:In this study, investigators aim to reveal the harmful effects of increasing consumption of homemade beer in recent years on the urinary tract. The high amount of carbonyl compounds in the content of homemade beer has been proven by studies. In this study, which will be conducted in the form of a questionnaire, it is aimed to evaluate the effects of the consumption of homemade beer and the long-term exposure of the urinary system to carbonyl compounds.
Smurf2 and bladder cancer - research proposal summary The Smurf2 gene was recently identified as a tumor suppressor gene. It is an E3 ubiquitin ligase and carries a significant role in major cellular processes such as cell division, genomic stability, DNA repair as well as resistance to anti-tumoral drugs. Recent studies showed that in several common tumors (prostate, breast, osteosarcoma etc.), a significant decrease in the expression or activity of Smurf2 can be noted, making the cells more susceptible to malignant transformation and the tumors more aggressive and highly resistant to various medications. Bladder cancer is no. 4 cancer in men and 6 in women, and a major cause of cancer related death. Common risk factors are smoking and occupational exposure to aniline dyes or aromatic amines. Its' most common presentation is painless hematuria. Once the diagnosis of a bladder tumor is made, endoscopic resection of the tumors is performed. Superficial tumors of low malignancy may be treated by repeated resections, highly malignant tumors require additional therapy and aggressive tumors invading the bladder muscle layer require radical surgery and chemo-radiotherapy. Therefore, all patients are closely monitored by repeated cystoscopies (endoscopic inspection of the bladder), each 3 months, lifelong. In an effort to minimize patients' discomfort, there is a constant search for a reliable biomarker in the urine of patients. A marker with good sensitivity and specificity will predict in a noninvasive fashion early recurrence or absence of bladder tumors, sparing the need for invasive cystoscopy. The presence of a biomarker may be used as prognostic factor or a measure of response to therapy. The aim of this research is to characterize the presence of smurf2 in bladder tumors and determine whether it may be utilized as a reliable biomarker for bladder cancer.
Treatment of metastatic tumors of the urogenital area with cytokine-induced killer cells
Urinary bladder cancer is a common malignant tumor of the urinary tract in both men and women. Proper management of the urinary bladder cancer depends on the stage of the lesions. Differentiating the histopathological types, tumor grade and the depth of tumor invasion are very important for determining the therapeutic approach and are highly correlated with the recurrence, progression and patient's survival. Radical cystectomy (RC) and lymphadenectomy after neoadjuvant chemotherapy is the standard treatment for muscle invasive tumors, whereas the treatment of choice for non-muscle invasive tumors is transurethral resection (TUR) ±chemo/immunotherapy. Cystoscopy with biopsy is still the best tool for bladder cancer staging due to its high sensitivity in detecting lesions and the possibilities of tumor resections, but the main drawbacks are invasiveness, limitation in detection of flat lesions, and lack of the assessment of extra-vesical tumor invasion. Modern diagnostic modalities circumvent these limitations like blue-light cystoscopic examination and infrared cystoscopy. For the radiological evaluation of the urinary bladder, magnetic resonance imaging (MRI) is a valuable imaging modality due to high tissue contrast and multiplanar imaging capabilities. Diffusion-weighted images provides useful information for evaluation of local T stage of the urinary bladder cancer, specially in differentiating T1 stage or lower tumors from T2 stage and higher tumor stages. Apparent diffusion coefficient (ADC) delineating the degree of water molecular diffusion and the degree of restriction to water diffusion in biological tissues is inversely correlated to the integrity of the cell membranes and the tissue cellularity. The apparent diffusion coefficient (ADC) value has been revealed as quantitative measure of the degree of malignancy of the lesions. Decreased ADC values were reported with malignant lesions which have a larger cell diameter and more cellularity than normal tissue.
The aim of this study is to evaluate the effect of Verity-BCG in patients with intermediate and high-risk non-muscle-invasive bladder cancer (NMIBC) and to compare our findings to the standard of care BCG formulation, OncoTICE (BCG) in order to examine our hypothesis that Verity-BCG is at least non-inferior to OncoTICE in achieving 24-month Recurrence Free Survival in NMIBC patients who are at high risk of recurrence and have never been treated with intradermal or intravesical BCG before, with the exception of tuberculosis vaccination in childhood.
To compare the perioperative, functional, and oncologic outcomes between non nerve sparing and nerve sparing robot-assisted radical cystectomy with orthotopic ileal neobladder in male patients with bladder cancer.
The purpose of this project is to explore whether Monoclonal Antibody-MMAE Conjugate for Injection (RC48-ADC) combined with Triplizumab as a preoperative neoadjuvant therapy for myometrial invasive bladder cancer (MIBC) can achieve a good tumor descending period, so as to prolong disease-free survival and overall survival.
The AFU has set itself the task of setting up a register of medical practices in order to define possible improvements in the therapeutic management and follow-up of NMIBC. In order to obtain representative data, all urologists who are members of the AFU may be invited to include their patients in accordance with the rules of clinical research.
The primary objective of this study, sponsored by Travera in Massachusetts, is to validate whether the mass response biomarker has potential to predict response of patients to specific therapies or therapeutic combinations using isolated tumor cells from varying cancers and biopsy formats.
Clinical trial to investigate the relationship between the expression of immunohistochemical biomarkers GATA-3, CK20, P53 and Ki67 in bladder cancer and pathological complete response after neoadjuvant chemotherapy.
