Filter by:To evaluate the activity of intravesical administration of CG0070 and intravenous administration of Pembrolizumab in patients with tissue pathology-confirmed non-muscular invasive bladder cancer (NMIBC) who have Bacillus-Calmette-Guerin (BCG) unresponsive disease with carcinoma in situ (CIS) with or without Ta/T1 papillary disease.
A single-arm, two-stage, open-label, phase 2 study investigating the safety and efficacy of intravesical gemcitabine/docetaxel for bacillus Calmette-Guerin (BCG)-naïve patients with non-muscle invasive bladder cancer (NMIBC).
Gastric cancer and colorectal cancer are common gastrointestinal malignancies in the world.Early cancer generally has no obvious symptoms. Endoscopy is the "gold standard"for the diagnosis of gastric cancer and colorectal cancer.gastric cancer and colorectal cancer treatment mainly includes surgery and medication.Compared with traditional diagnosis and treatment methods, the application of gene detection technology, especially high-throughput sequencing technology (NGS) in tumor diagnosis and treatment, performs multi-dimensional and multi-target detection of cancer-related genes, which can quickly and accurately determine the target gene mutations Morphology and expression differences, so as to provide personalized guidance to patients in terms of medication, treatment or prognosis evaluation, which can save a lot of time and treatment costs, and improve the overall treatment effect and patient quality of life. Cystoscopy and biopsy sampling pathological testing are the gold standard for bladder cancer diagnosis, and have been widely used in clinical diagnosis and prognosis judgment. However, cystoscopy is cumbersome, expensive, and often causes pain to the patients under test. At present, the main clinical non-invasive detection technique for bladder cancer is still the cytological examination of urinary tract bladder cells in urine, and its sensitivity and specificity are not good, especially for the diagnosis of early lower grade bladder cancer.For bladder cancer, tumor tissue (puncture biopsy or surgical resection) DNA, urine ctDNA, urinary tract exfoliated cell DNA and peripheral blood ctDNA can be used for genetic testing, but the consistency of the genetic testing results of these four types of samples has not been verified, especially There is no systematic evaluation of the guidance effect of non-invasive gene detection of free tumor DNA and urinary tract shed cell DNA in the diagnosis and treatment of bladder cancer.The corresponding relationship between the significant mutation genes contained in the DNA derived from bladder urinary tract cancer and the various types and stages of bladder cancer is not clear.
This pilot study is evaluating how well pembrolizumab and combination chemotherapy before surgery work for the treatment of specific types of muscle-invasive bladder cancer that have unusual appearance (variants). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as methotrexate, vinblastine, adriamycin, and cisplatin work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving pembrolizumab and combination chemotherapy before surgery may work better in treating patients with these muscle invasive bladder cancer variants compared to chemotherapy alone.
eRapa (encapsulated rapamycin) will be investigated for secondary prevention in patients with diagnosed non-muscle invasive bladder cancer (NMIBC) through a phase II double-blind randomized controlled trial of long-term (one year) prevention with eRapa versus placebo. The primary hypothesis is that eRapa decreases the risk of cancer relapse for patients with NMIBC. Secondary hypotheses are that eRapa can improve certain immune parameters and improve cognition and physical function without adversely affecting patient-reported outcomes and quality of life.
This is a phase Ib study of the safety and performance of a novel intravesical contrast-enhanced Magnetic Resonance Imaging protocol for determination of bladder cancer stage prior to transurethral resection of bladder tumor (21 subjects) or prior to radical cystectomy for muscle invasive disease (21 subjects). Subjects will undergo a single MRI study: a pre-contrast, single breath hold image followed by sterile placement of a temporary urethral catheter for instillation of a 50mL solution containing Gadobutrol (4 mM) plus ferumoxytol (5 mM) and then a second, post-contrast image. Images will be reviewed by two dedicated abdominal radiologists, who are blinded to the pathologic staging, for determination of tumor presence and depth of bladder wall penetration.
This is an observational study utilizing a qualitative descriptive methodology with a thematic analysis approach to explore the impact of a preoperative educational intervention ("Stoma Bootcamp") on patients and their family/informal caregivers
Treatment of localized muscle invasive bladder cancer (MIBC) is radical cystectomy. Neoadjuvant chemotherapy (NAC) improves survival. Approximately 50-60% of all MIBC patients undergoing NAC before cystectomy are histopathological without remnant tumor in the cystectomy specimen (T0). However, there is currently no optimal method to evaluate whether the patient is true T0 or has remnant tumor in need for consolidating radical treatment. The study aim is to investigate if 15O-H2O PET/MR can predict complete local response to neoadjuvant chemotherapy in patients with MIBC and thereby identify potential candidates for organ preservation.
This retrospective study aimed at assessment of different patterns (morphological and pathological) of tumor recurrence found at first evaluation after BCG induction therapy (3 months cystoscopy) for intermediate and high-risk NMIBC and its prognostic implications at a tertiary referral center.
Our goal is to develop a noninvasive, fast and simple assay to detect BCa on the GeneXpert system and metablomic genes.
