Filter by:VET3-TGI is an oncolytic immunotherapy designed to treat advanced cancers. VET3-TGI has not been given to human patients yet, and the current study is designed to find a safe and effective dose of VET3-TGI when administered by direct injection into tumor(s) (called an intratumoral injection) or when given intravenously (into the vein) both alone and in combination with pembrolizumab in patients with solid tumors (STEALTH-001).
Pear Bio has developed a predictive biomarker technology that combines 3D cell culture, microscopy and computer vision to measure the response of an individual patient's tumor sample to different systemic therapy regimens that are tested simultaneously ex vivo. This study will recruit patients with advanced or metastatic kidney cancer who are due to start a clinically-indicated new line of therapy. The oncologist will be blinded to the response on the Pear Bio test (the test will be run in parallel with the patient's treatment). The primary objective of this study is to establish the sensitivity and specificity of Pear Bio's test results against patient outcomes (objective response, progression-free survival, depth and duration of response, overall survival).
The goal of this clinical trial is to test the utility of patient navigation by comparing high intensity patient navigation to low intensity navigation approaches to improving cancer trial enrollment of patients treated in academic and community cancer centers. Patient navigation is a strategy for increasing patients access to cancer care by helping the participant overcome barriers in the participants communities and within the health care system by providing a bridge between the patient and the health care system. The primary objective of this study is to determine if a high intensity patient navigation program will improve patients enrollment on clinical trial in comparison to a low intensity patient navigation. Participants who agree to participate and are eligible will be randomly assigned to either the high intensity or low intensity approach.
The purpose of this study is to determine the safety and tolerability of acarbose in combination of immunotherapy based standard of care therapy in advanced renal cell carcinoma patients.
This study will develop a whole-of-body markerless tracking method for measuring the motion of the tumour and surrounding organs during radiation therapy to enable real-time image guidance. Routinely acquired patient data will be used to improve the training, testing and accuracy of a whole-of-body markerless tracking method. When the markerless tracking method is sufficiently advanced, according to the PI of each of the data collection sites, the markerless tracking method will be run in parallel to, but not intervening with, patient treatments during data acquisition.
The purpose of PRORECECA is to test whether adding weekly active patient-reported outcomes to the treatment of patients with metastatic renal cell carcinoma can improve patient-reported physical function.
To establish whether surgical planning using virtual 3D modelling (Innersight 3D) improves the outcome and cost-effectiveness of RAPN, allowing more patients to benefit from minimally-invasive procedures.
The incidence of renal cysts is rising due to increased abdominal imaging. Renal complicated cysts have been traditionally classified according to the Bosniak classification, which distinguishes cystic masses by specific features of walls and septa. The categories I and II are benign and class IIF most probably benign but needs a short radiological follow-up. Categories III and IV have been traditionally operated due to the increased risk of renal cell carcinoma. However, recently published studies show that approximately 50% of the operated Bosniak III cystic masses are benign, which means that half of the cases are overtreated by surgery. It has also been shown that surgical pathology of stable Bosniak IIF cysts is malignant in less than 1%, while the cysts, which are upgraded to higher Bosniak classes will show malignant surgical pathology in 85%. So far, there is lack of prospective data on active surveillance in Bosniak III cystic masses. The aim of the study is to compare active surveillance and surgery in patients with Bosniak III renal cystic masses. Patients will be randomized in active surveillance or immediate surgical excision of a cystic mass. In the active surveillance group, patients are followed according to the study protocol for 10 years and treated with delayed surgery if the cystic mass upgrades into Bosniak IV/solid, becomes symptomatic or grows over a preclassified threshold. The primary objective is to compare surgical pathology between patients treated with immediate surgery versus delayed surgery. According to recent retrospective data, active surveillance of Bosniak III cystic masses is reasonable and oncologically safe. Therefore a prospective randomized controlled trial is needed to get high level evidence to support a change in the treatment strategy. The study may significantly reduce unnecessary operations performed in patients with Bosniak III cystic masses.
Introduction The current limitations of renal cell carcinoma (RCC) imaging form a major deficit in the diagnostic pathway. Contrast Enhanced UltraSound (CEUS) has the potential to improve RCC detection and localization significantly. CEUS image interpretation is however difficult and subjective. To overcome these difficulties a CEUS quantification technique, Contrast-enhanced Ultrasound Dispersion Imaging (CUDI), has been developed in cooperation with the Eindhoven University of Technology (TU/e). Study objective Primary objective: To assess the sensitivity and specificity of CUDI for recognizing malignant tissue in vivo. Study population All patients scheduled for a partial or radial nephrectomy in the Amsterdam UMC (Amsterdam Universitair Medische Centra) Study Procedure This study is a prospective in-vivo study in patients scheduled for a partial or radical nephrectomy for a suspicious RCC in which we will perform CEUS imaging. The (partial) nephrectomy is part of standard care for patients with a suspicious lesion in the kidney. The additional ultrasound with infusion of an ultrasound contrast agent during ultrasound scanning is performed for the purpose of the study. CEUS imaging will be performed right before (partial) nephrectomy, with the patient being under general anesthesia. The CEUS and CUDI parametric maps will be interpreted by Investigator A in a blinded fashion with suspicious lesions each delineated. The (partial) nephrectomy will be performed by a qualified urologist, and the analysis of the histological specimens will be performed by a qualified pathologist. Sensitivity and specificity for CUDI will be calculated for all patients receiving a (partial) nephrectomy in which the tissue is sent for pathology. Benefits Currently, most renal tumors are diagnosed by abdominal US, CT or MRI. Renal tumors are classified as cystic or solid lesions on imaging. The most important criteria for differentiating malignant lesions is the presence of enhancement after administration of contrast for CT or MRI in several different phases (4 phases CT-scan). Enhancement in renal masses is determined by comparing Hounsfield units before and after administration of contrast. A change of 15 or more Hounsfield units demonstrates enhancement. Specificity and sensitivity for detecting RCC are around 75% and 88% for CT, and around 89% and 87.5% for MRI, respectively. Both CT and MRI can objectify a contrast-enhancing mass, suspicious for RCC, however, they cannot reliably distinguish a benign lesion (such as an oncocytoma or angiomyolipoma) from a malignant renal neoplasm. For that reason, patients are currently undergoing an RTB (renal tumor biopsy) to objectify pathology for deciding if treatment is necessary or not. Recent literature suggests up to 30% benign pathology after partial nephrectomy implicating overtreatment. RTB has been gradually introduced and increasingly used, however, an RTB is not without risks. Bleeding is the most documented complication. Recently even tumor tract seeding has been under discussion. Improving imaging by using CUDI for differentiating benign from malignant lesions instead of performing an RTB could prevent those risks for patients. Risk assessment There is a small risk of contrast-related adverse events (AE) for participants. After use in millions of patients, AE to the ultrasound contrast agent appear to be transient, mild and rare, and mostly consist of transient alteration of taste, local pain at the injection site and facial or general flush. In some cases, a mild allergic reaction is described. Patients will be informed of the risk during contrast exposure, and it will be described in the patient information file.
French patients with nephroblastoma (Wilms tumour, WT) have been treated for > 40 years according to International Society of Paediatric Oncology (SIOP) protocols with currently 267 centres across 28 countries collaborating internationally within the SIOP Renal Tumour Study Group (RTSG). Over the last decades more than 10,000 children have been prospectively enrolled in SIOP WT studies and trials. This has resulted in more standardised diagnostic procedures, improved risk stratification, and adjusted treatment recommendations for most renal tumours. The treatment of patients with renal tumours according to SIOP protocols include preoperative chemotherapy, surgery (tumour-nephrectomy + node-picking ± metastasectomy) followed by risk- and stage-based postoperative chemotherapy ± radiotherapy. Central pathology review is nowadays routinely performed in order to prevent misclassification of stage and histology risk group. The current SIOP 2001 protocol has come to an end with as major achievement the scientific proof of omitting doxorubicin in stage II and III patients with as a consequence less risk of sequelae. Moreover, in the SIOP 2001 protocol, several tumour biological aspects have been assessed that seem to interfere with outcome (chromosomal gain of 1q, or loss of 1p and 16q, blastemal residual volume). Chromosomal 1q gain is considered to be present in 25-35% of patients with nephroblastoma with a negative impact on event-free survival (EFS) in retrospective analyses. These biological aspects will be studied prospectively as a primary objective in the new SIOP RTSG 2016 UMBRELLA protocol that integrates diagnostics, treatment and follow-up guidelines as well as several research projects. The main mission of the International Society of Paediatric Oncology (SIOP) Renal Tumour Study Group (RTSG) is to increase survival and to reduce acute treatment toxicity and late effects in all children diagnosed with any renal tumour. In this context, SIOP RTSG is aiming to offer all these patients the same standardized high quality diagnostics and treatment, independent of the tumour type. The new SIOP RTSG 2016 integrated diagnostic and research UMBRELLA protocol serves as an entry for including all children with a renal tumour in the SIOP-RTSG centers, including prospective biomarker analyses. Subsequently, treatment is recommended according to the SIOP RTSG 2016 UMBRELLA treatment guidelines, which provides treatment strategies for all patients with Wilms tumour (WT) and other renal tumours. Central radiology review (CRR) has been proposed as a novel tool within the diagnostic UMBRELLA protocol in order to optimize the diagnostics and hence the treatment. The definition of metastatic disease in WT remains difficult since pulmonary nodules may not always be of malignant origin. The differential diagnosis of a pulmonary lesion seen in a child with WT is broad. In addition to malignancy, it includes atelectasis, fibrosis, pneumonitis, subpleural lymph nodes, and other infectious or inflammatory lesions. In addition, the issue of "CT-only" nodules in WT and adequate treatment needs to be solved. In previous protocols, the treatment strategy was based on the diagnosis of pulmonary metastases (92% of all metastases) by conventional pulmonary X-ray. Patients with CT-only nodules (= nodules not visible on conventional X-ray) were supposed to be treated as having localized WT. However, retrospective analyses of SIOP series (Smets et al), showed that patients with CT-only nodules had a less favourable prognosis as compared to patients with truly localized disease with a 12% difference in three-year event-free survival. The diagnostics of bilateral renal tumours (stage V) often is complicated since it may be difficult to distinguish true WT from nephroblastomatosis/ nephrogenic rests, a pre malignant renal (multifocal) anomaly, which may respond to preoperative chemotherapy. An optimal multi-disciplinary sequential diagnostic procedure is required in order to propose the best adapted therapeutic approach to preserve sufficient renal tissue.
