Filter by: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.
This research study involves the use of two navigation systems, the 3D Slicer-based navigation system, and the Siemens Monaco systems, to simplify the complexity of image-guided lymphadenectomy procedures (surgery to remove one or more lymph nodes) in patients with urological cancer.
The aim of this study is to evaluate the outcomes of transvaginal natural orifice specimen extraction (NOSE) in patients who are planning multiport laparoscopic surgery for resection of solid organs including kidney, liver, stomach, adrenal gland and bladder.
This is a prospective randomized controlled trial of patients undergoing major urologic-oncologic surgery at the University of California, San Francisco (UCSF) Medical Center and the Helen Diller Family Comprehensive Cancer Center. This clinical trial examines the effect of guided meditation before surgery on the levels of anxiety, stress, sleep disturbance, and quality of life among patients scheduled to undergo a major urologic surgery for cancer. A cancer diagnosis and the treatments associated with it can be very stressful for patients, leading to depression, sleep disturbances, and lower quality of life. Mind-body practices such as guided meditation have been used for thousands of years to reduce the effects of chronic stress and to improve quality of life. This clinical trial examines the effects of guided meditation on the stress, depression, and quality of life levels of patients undergoing urologic surgery for their cancer.
In this randomized prospective single-blind study,American Society of Anesthesiologists physical status classification system ( ASA )I-II-III patients aged 50-80 years undergoing transurethral bladder resection will be randomly divided into two groups. First group will be covered with 41 centigrade degrees double layered cotton cloth. Second group will receive active prewarming. Core temperature of all patients will be monitorized via tympanic membrane. Skin temperature will be monitorized from 4 different body areas. Spinal anesthesia will be applied at the level of L3-L4 by a 25 Gauge quincke needle with a dose of 12.5-15 mg hyperbaric bupivacaine. Pinprick test will be used for sensorial block assessment. T10 sensorial block will be our goal. Hemodynamic parameters will be recorded. Skin temperature will be monitorized before and after spinal anesthesia and changes will be recorded. Operation time, amount and temperature of irrigation fluids, transfusion requirement, discharge time from postoperative care unit will also be recorded. Shivering score and thermal comfort scale will be used. The two groups will be compared for the temperature changes.
Atezolizumab in patients with urinary tract squamous cell carcinoma: a single-arm, open-label, multicentre, phase II clinical trial
Robot-assisted surgery has been successfully adopted rapidly over the last decade. Robotic technology with tridimensional imaging can improve operating dexterity, visualization of difficult anatomic locations. This is a prospective study aims to evaluate the safety and effectiveness of the domestic surgical robot.
As population ages, geriatric patients with urinary tract cancer suffer from more complications and functional decline that alter treatment plan despite advance in cancer surgery. It was found that these urinary tract cancer survivors required a longer time to recover to the state before the treatment, and some may be even unable to recover to the state before the treatment. Exercise intervention has been found to be beneficial to improve functional capacity for cancer survivors, such as breast cancer. However, it is unclear whether exercise intervention could also improve functional recovery and mobility in patients with urinary tract cancer following curative surgery, especially in older adults. The purpose of this study is to investigate the effect of reconditioning exercise on morbidity, oncological outcomes, and functional recovery in older adults with urinary tract cancer following curative surgery. Patients aged over 65 years old and after having undergone curative surgery for confirmed urinary tract cancer will be recruited. The participants will be assigned into two groups using blocked randomization design. One group will receive reconditioning exercise training for five consecutive days, and the other group will receive exercise education. Structured questionnaire for comprehensive geriatric assessment and functional mobility, such as walking performance, will be used to assess the training effect. Outcome measures are assessed including major complication after surgeries, changes in functional status, tumor progression, and length of survival. Physical function measurement will include hand grip, muscle strength of lower extremities, and gait performance.
The study aims to investigate the rationale for LPN in patients with high-complexity renal tumors in terms of oncologic and functional outcomes.
To evaluate the efficacy and safety of a pembrolizumab therapy of pembrolizumab in combination with standard salvage radiation therapy (SRT) in patients with biochemical recurrence (BCR) of prostate-specific antigen (PSA) persistence after radical prostatectomy (RP).
