Evaluation of the PI-RADS v2.1 Score Using Multiple Readers
Prostate CancerUrological CancerThe interpretation of prostate multiparametric MRI (mpMRI) is difficult and requires expertise. As a result, it suffers from substantial inter-reader variability. The so-called Prostate Imaging Reporting and Data System (PI-RADS) scoring system has been launched in 2012 to try and standardise prostate mpMRI interpretation. It is a 5-level score that assesses the likelihood that suspicious focal prostatic lesions seen on mpMRI are clinically significant prostate cancers. Despite the use of semi-objective criteria for each category of the score, the inter-reader reproducibility of the first two versions (PI-RADS v1 launched in 2012 and PI-RADS v2 launched in 2015) was moderate at best, even for experienced readers. The last version (PI-RADS v2.1) has been launched in March 2019 in an effort to improve the inter-reader reproducibility. This version has not been evaluated yet. The purpose of our study is to evaluate the accuracy and inter-reader reproducibility of the PI-RADS v2.1 score on a large set of 171 prostate MRIs using 21 readers of varying experience. Twenty-one readers (14 seniors and 7 juniors) from 9 different institutions and with varying experience in prostate mpMRI accepted to participate to the study. Reader will assess the dataset independently and will be blinded to the other readers' results. They also be blinded to clinical and biochemical data.
Metastatic Prostate Cancer Men's Attitudes Towards Treatment of the Local Tumour and Metastasis...
Prostate Cancer MetastaticRadiotherapy Side Effect5 moreSystemic therapy (i.e Androgen Deprivation Therapy with Docetaxel, Enzalutamide, Apalutamide or Abiraterone Acetate) has increased overall survival in men with hormone-sensitive metastatic prostate cancer. Novel local cytoreductive treatments and metastasis directed therapy are being evaluated, these can confer additional harm, but might improve survival. We aim to elicit men's preferences for and willingness to accept trade-offs between potential improved survival and cytoreductive treatment risks using a 'discrete choice experiment'.
INJECT: A Pilot Study of Intra-tumoral Injections in Metastatic Urological Cancers
Metastatic Castration-resistant Prostate Cancer (mCRPC)Metastatic Urothelial Carcinoma1 moreThe purpose of this study is to plan for future clinical trials in patients with metastatic urological cancers. Diluted iodinated contrast will be injected intra-tumorally under CT fluoroscopy guidance into bone, lymph node, soft tissue and liver metastases in subjects with metastatic prostate cancer, urothelial carcinoma, or renal cell carcinoma. Pre- and post-injection CT images will be obtained to determine the injection parameters needed for optimal distribution throughout metastases of a given size. A biopsy of the metastatic site will also be obtained to validate expression of the receptor CD155.
Long-term Cancer Risk in the Randomised Oslo Diet and Antismoking Study
CancerGastrointestinal Cancer3 moreThis study examines the effect of a five-year multifactorial lifestyle intervention in the Oslo diet and antismoking study on long-term cancer risk. In 1972-1973, 1232 men with high cardiovascular risk profile were randomised to intervention including cholesterol lowering diet, weight loss and antismoking advice, or control (1:1). This study examines the effect of the intervention on 43-year cancer incidence and mortality.
Investigation and Detection of Urological Neoplasia in Patients Referred With Suspected Urinary...
Urothelial CarcinomaBladder cancer is common in the UK and can kill. A common sign of bladder cancer is blood in the urine (haematuria). GPs will refer to a specialist (Urologist) for further investigation of haematuria if they suspect cancer. Hospitals often have a 'blanket' approach for investigating patients with haematuria. IDENTIFY will collect data on patients having these tests across the UK and internationally, looking at any trends with an aim to create a personalised diagnostic approach for each patient. The data will give patients the ability to make informed decisions, as well as reducing unnecessary and potentially harmful tests.
Platelet-lymphocyte and Neutrophil-lymphocyte Ratio in Patients Undergoing Cancer Surgery
CancerUrologic Neoplasms1 moreCancer is a major cause of morbidity and mortality worldwide. Despite the use of surgery in an attempt to cure the majority of solid tumors, metastasis from residual cancer cells still remains a major cause of morbidity and mortality. General anesthesia and surgical stress during surgery suppress the immune response by directly affecting the immune system or by activating the hypothalamic-pituitaryadrenal axis and the sympathetic nervous system. The aim of our prospective observational study was to assess the value of neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio regarding outcome underwent cancer surgery. Primary aim is to assess the preoperative and postoperative values of inhalational anesthesia vs total intravenous anesthesia.
Unmet Supportive Care Needs in Bladder Cancer Patients Undergoing Radical Cystectomy
Bladder CancerUrologic Cancer1 moreNowadays, high-quality cancer care is more than just diagnosis and treatment of cancer. Healthcare must respond to the specific needs of the patients to provide patient-centered care. To date, research on the unmet supportive care needs in bladder cancer patients undergoing radical cystectomy is scarce. Because the needs of the patients may differ according to the phase in the illness trajectory, it is important that prospective research is carried out. Research in other cancer populations shows that unmet supportive care needs are negatively associated with health-related quality of life, psychological distress, physical activity and the health literacy of the patient. By incorporating the above factors into this study, we can not only map the unmet supportive care needs of the patient, but also explore possible associations between the variables. Since this is the first prospective study on supportive care needs in bladder cancer, this is a hypothesis-generating study.
Antegrade Double-J Stent Placement for the Treatment of Malignant Obstructive Uropathy
Urologic NeoplasmsUreteral double- J stent is usually inserted by retrograde approach for the treatment of obstructed upper urinary tract. The antegrade approach, can a suitable alternative in certain situations without the need for general or spinal anesthesia. The present study demonstrates the indications, success rate, and complications of this approach in the treatment of malignant obstructive uropathy.
Genetic Analysis of Inherited Urologic Malignant Disorders: Collection of Samples
Neoplastic SyndromesHereditary1 moreInvestigation of the causes of genetic defects relating to hereditary urologic malignancies will be undertaken. These rare disorders result from inherited or newly arising mutations in genes involved in the development and function of different organ systems. As specific disease syndromes are recognized and the responsible genes identified, mutations in individual families can be identified. Correlation of mutation sites with clinical information will help determine how specific gene segments encode important functional protein domains. Families with urologic malignant disorders of known or suspected genetic basis will be enrolled. Genetic linkage studies will include all available family members, while gene sequence analysis will be performed on affected individuals. Unaffected family members or unrelated normal individuals will serve as controls. The family members will be identified by the proband or proband's parent when the initial pedigree is taken. Subjects considered by the investigators to be appropriate for linkage studies will be invited to participate by the local genetics provider or by the investigators, who will then connect these members to their own local providers for enrollment. In our studies of inherited urologic malignant disorders, there may be individuals from renal cancer families who do not undergo clinical evaluation for the presence of an inherited urologic malignant disorder at the National Institutes of Health because of their health problems, geographical location, or personal preference. Even though these individuals do not undergo a clinical evaluation of their suspected inherited urologic malignant disorder at the National Institutes of Health, they may have rare diseases that are extremely important to study. Therefore, we intend to collect blood samples for genetic studies from these individuals to facilitate linkage analysis and disease gene identification. Samples will be collected either by the individual's physician and sent to NIH, or will be collected by NIH physicians at either the individual's off-site location or at the NIH.
