Care of the Urothelial Cancer Patient and Prospective Procurement of Urothelial Cancer Tissue

Overview

Background: Urothelial cancer is cancer of the bladder, ureter, and urethra. Researchers want to better understand what changes in a person s cells and genes cause this cancer to form. This may help them find new ways to treat it. Objective: \- To perform DNA sequencing to help researchers learn the differences between normal tissue and tumor tissue. Also, to learn how molecular changes - including gene changes - might help predict the course of disease and how people respond to therapy. Eligibility: \- Adults age 18 and older who have or are suspected of having urothelial cancer or an inherited disorder that raises their risk of getting bladder cancer. Design: * Participants will be screened with a physical exam. Their medical records and tissue samples will be reviewed. * Eligible participants will give tissue blocks of their original tumor. The blocks will be put in a tissue bank. * Participants medical records may be reviewed. * Participants may have a medical history and physical exam. * Participants may have blood and urine tests. They may have imaging scans. They may give urine, blood, and saliva samples. These samples may be used in future research. * If participants need surgery for their cancer, researchers will keep some of the tissue (both tumor and normal tissue). The tissue may be used in future research. * Participants will go back to the Clinical Center in 6 months. They may give saliva, urine, and blood samples. After 6 months, they will be seen by their local doctor for standard post-surgical visits. * Participants will be called every 6 months to give health updates.

Background: * Urothelial carcinoma, present as lower or upper urinary tract disease, is the most expensive malignancy to treat from diagnosis to death, and no major advances in drug therapy have taken place in the last two decades. * Understanding the molecular mechanisms and genomic alterations that cause urothelial carcinoma will provide the foundation for the development of novel targeted therapeutic agents for this disease. Since 1982 investigators in the Urologic Oncology Branch have been studying the genetic basis of urologic cancers. The identification of the genes for cancer of the kidney has led to the approval by the FDA of a number of new agents for patients with advanced disease. Similarly, it is our goal to study the cancer biology (genomic, molecular, and cellular biology) of urothelial carcinoma in order to develop novel treatment strategies. * Collection of patient tumor samples allows us to study molecular and biologic pathways and develop novel targeted therapies. Correlation of these samples with clinical outcomes in patients allows us to predict and understand clinical outcomes and possibly develop predictive and/or prognostic biomarkers. * Collection of blood, urine and saliva from healthy volunteers will allow us to distinguish normal and inflammatory conditions from malignant diseases. Furthermore, the specimens will provide appropriate controls for comparison. Objective (Primary): * Collect blood, urine, and benign and malignant tissue from patients with known or suspected urothelial cancer for the purpose of elucidating the molecular mechanisms of carcinogenesis in urothelial cancer and ultimately, identifying novel therapeutic targets. * Collect blood, urine and saliva from healthy volunteers for the purpose of establishing controls for comparison with urothelial cancer specimens. Eligibility: * Adults with biopsy-proven or suspected urothelial cancer who require diagnostic or therapeutic intervention as part of their diagnosis, standard of care treatment, or followup/surveillance for their neoplasm. * Healthy volunteers from whom blood, saliva and urine samples are easily obtainable. Design: * Care of the patient with urothelial carcinoma will be provided as per medically indicated standards and in the process, normal and malignant urothelial cancer tissues may be obtained at the time of clinically indicated diagnostic and/or therapeutic intervention. * Blood, urine, and saliva samples for research may be obtained from patients and healthy volunteers at baseline. Additionally, blood and urine may be collected from patients at follow-up intervals. * No investigational or experimental therapy will be given as part of this protocol.
