Filter by:Various factors determine the long term survival in this non-uniform cohort of incidental gallbladder cancer. Timing of re-intervention is suggested to play an important role in the outcome. Few centers are proponents of early surgery in order to prevent dissemination, while others have suggested an intentional delay of 3 months to filter out cases with aggressive pathology. In the present study, investigators intend to evaluate the factors affecting survival in incidental Gallbladder Cancer (IGBC) with special reference to timing of re-intervention.
Investigators performed the Genetron Uro V1 test on the urine of patients before secondary TURBT and compared it with the final pathological results. To analyze the performance of the Genetron Uro V1 method in a study to predict the need for secondary TURBT in high-risk NMIBC patients and the correlation with patient's RFS and OS.
This proposal will aim to improve the understanding about the treatment decision in the type of urinary diversion and identify patient knowledge gaps about uncertainty around patient decision-making.
Treatment of metastatic tumors of the urogenital area with cytokine-induced killer cells
The aim of the study is to assess the feasibility of genomic and epigenetic analysis of rectal mucus to detect non-colorectal cancers of the aero- digestive tract using samples collected by the OriCol™ Sampling Device. The primary objective of the study is to assess whether significant changes in DNA mutation and methylation associated with Non-colorectal cancers of the Aero- digestive Tract (NCRCADT) can be detected in rectal mucus as shed cells and cell-free DNA (cfDNA) pass through the gut and theoretically can be collected from rectal mucus. Secondary objectives will assess the participant acceptability of the OriCol™ Sampling Device for Upper GI and Lung Pathology as well as contributing to a genomic library collating information about rectal mucus.
Bladder Cancer (BCa) is the 9th most common cancer worldwide. In general, BCa is presented as a non-muscle invasive bladder cancer (NMIBC) in 70% of patients and treated with transurethral resection of bladder tumor (TUR-BT). However, in cases of muscle invasive bladder cancer (MIBC), radical cystectomy (RC) is the gold standard of treatment. Therefore, It is important to distinguish MIBC from NMIBC. To date, pathologic staging is based on the result of TUR-BT before RC. However, it is operator dependent, thus residual cancer may be remained depending on surgical experience. Therefore, about 7%-30% patients of MIBC can be underestimated with NMIBC, and it can be increased to 45% if the muscle is not resected. Consequently, it has been raised the need for imaging test to overcome diagnostic limitations. Multiparametric magnetic resonance imaging (mpMRI) has been widely used in the field of diagnosis of BCa. In 2018, the Vesical Imaging Report and Data System (VI-RADS) was published using T2-weighted imaging (T2WI), diffusion-weighted imaging (DWI), and dynamic contrast enhanced (DCE) imaging, and 5-point VI-RADS scoring system has been proposed and reported as an imaging test useful for assessing muscle involvement in primary bladder cancer Therefore, in this study, we investigate the diagnostic performance of the VI-RADS scoring system that can differentiate NMIBC from MIBC in primary bladder cancer.
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.
This study was a prospective, multicenter observational clinical study, A total of 150 patients with bladder malignant tumor who was admitted to the urology department of each center for treatment and underwent electric resection or radical cystectomy were planned to be enrolled. In order to analyze the sensitivity、specificity and accuracy of artificial intelligence in predicting postoperative pathological staging, Patients who entered the group were followed up for 3 years, then, we analyzed the correlation between artificial intelligence prediction results and patient OS PFS RFS. It was preliminarily verified that the results of the artificial intelligence model have the potential to predict the prognosis of patients with bladder cancer.
This phase III trial compares the effect of adding cabozantinib to avelumab versus avelumab alone in treating patients with urothelial cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as avelumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cabozantinib and avelumab together may further shrink the cancer or prevent it from returning/progressing.
This study is open-label dose expansion study to investigate the safety and toxicity of intravesical treatment of high-grade NMIBC (HGTa or CIS, including CIS with concomitant Ta) after transurethral resection of bladder tumor (TURBT) and/or biopsy using TARA-002 in adults unable to obtain intravesical Bacillus Calmette-Guérin (BCG), adults who have received at least one dose of intravesical BCG or adults who have received at least one dose of intravesical chemotherapy. After completion of the dose escalation phase (Phase 1a) and after the RP2D has been established, the dose expansion phase (Phase 1b) will start enrollment of subjects with CIS NMIBC with active disease to further evaluate the safety and preliminary efficacy of TARA-002, at the established RP2D. CIS NMIBC with active disease is defined as disease present at the last cystoscopic evaluation prior to signing the ICF. Subjects enrolled in the dose expansion phase will not include subjects previously enrolled and treated in the dose escalation phase. All subjects will receive 6 weeks of treatment at the established RP2D.
