Active clinical trials for "Ureteral Neoplasms"

RATIONALE: Sunitinib malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. PURPOSE: This phase II trial is studying the side effects of giving sunitinib malate and to see how well it works in treating patients with locally recurrent, locally advanced, unresectable, or metastatic urinary tract cancer.

This is a Phase Ib/II, open-label, multi-center, competitive enrollment and dose-escalation study of ALT-801 in a biochemotherapy regimen either containing cisplatin and gemcitabine or containing gemcitabine alone in patients who have muscle invasive or metastatic urothelial cancer of bladder, renal pelvis, ureters and urethra. The purpose of this study is to evaluate the safety, determine the maximum tolerated dose (MTD) and the recommended dose (RD), and assess the anti-tumor response of ALT-801 in combination with cisplatin and gemcitabine or ALT-801 in combination with gemcitabine alone. The pharmacokinetic profile of ALT-801 in combination with cisplatin and gemcitabine will also be assessed. The study includes a dose escalation phase (Phase Ib) and a dose expansion phase (Phase II). Phase II has two treatment groups, Expansion Group 1 and Expansion Group 2. Expansion Group 2 is for platinum-refractory patients, consisting of two treatment arms based on the patient's renal function. Patients will enroll to Expansion Group 2 after stage 1 of the Group 1 expansion is complete.

RATIONALE: Studying samples of blood and urine from patients with cancer and from healthy participants in the laboratory may help doctors identify and learn more about biomarkers related to cancer. PURPOSE: This laboratory study is looking at biomarkers in patients with kidney cancer or cancer of the urothelium and in healthy participants.

Rationale: Initial evaluation usually consists of cross sectional imaging of the urinary tract. When a suspect lesion is seen, an ureterorenoscopy is planned to visualize the lesion and to collect tissue for histopathology. These techniques are considered to be the gold standard in diagnosis of UTUC. CLE, a high resolution imaging technique that can be used in combination with endo-urological procedures, seems promising to improve diagnosis of urothelial cancer. CLE image characteristics for UTUC still have to be defined. Objective: With this IDEAL stage 2b explorative pilot study the investigators aim to assess in-vivo CLE image characteristics of normal urothelium, benign urothelium and urothelial carcinoma (low-grade, high-grade or CIS) of the upper urinary tract by qualitatively comparing CLE images with both histopathology from diagnostic biopsies and pathology from the therapeutic radical nephroureterectomy. Secondary objectives are the development of an imaging atlas and to assess the technical feasibility and procedure related adverse events of CLE.

Telerounding is the use of wireless remote video-confrencing to assess hospitalized patients. Physicians thus rely on all ususal data collected during bedside rounds with the exeption of a direct physical exam. The intention of this study is to determine if post-operative morbidity can be identified in an accurate and timely manner.

Upper tract urothelial carcinoma (UTUC) diagnosis include urography using computed tomography urography (CTU) or urography using MRI (MRU). The sensitivity of CTU decreases substan¬tially with decreasing lesion size. Other drawbacks of CTU include the radiation exposure and potential adverse effects in patients with allergic reactions or pre-existing renal impairment. In terms of urine cytology, the major drawbacks of urine cytology are low sensitivity and highly dependent of the experience and skills of the cytopathologist. We here intended to investigate whether UroCAD can be added in the diagnostic work-up of UTUC patient, and improve the accuracy of predicting UTUC before surgery.

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This study is looking at genetic susceptibility to cancer and interactions between genes and the environment in patients with cancer in East Anglia, Trent, or West Midlands of the United Kingdom.
