Urothelial CarcinomaNCT01378052
DNA Methylation and Urothelial Carcinoma
An observational study of Urothelial Carcinoma, run by China Medical University Hospital at 1 site in Taiwan.
Trial summary
Many studies previously showed the significant association between urinary arsenic profiles and urothelial carcinoma (UC) risk and observed the increased UC risk in people with lower plasma folate and higher homocysteine than those with higher plasma folate and lower homocysteine.

Study population: This is a hospital-based case-control study. Patients with urothelial carcinoma are recruited by pathological verification of UC was done by routine urological practice including endoscopic biopsy or surgical resection of urinary tract tumors followed by histopathological examination by board-certified pathologists. Healthy controls without evidence of UC or any other malignancy were recruited including those receiving adult health examinations at China Medical University Hospital.

About this study
Official title: Level of DNA Methylation in People With Urothelial Carcinoma
Many studies previously showed the significant association between urinary arsenic profiles and urothelial carcinoma (UC) risk and observed the increased UC risk in people with lower plasma folate and higher homocysteine than those with higher plasma folate and lower homocysteine. The investigators would expect to explore the interactions among global DNA methylation, one-carbon metabolic pathway factors, urinary arsenic profiles and UC.

Questions about this trial
What is this clinical trial studying?
An observational study of Urothelial Carcinoma, run by China Medical University Hospital at 1 site in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 22 Jun 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Chao-Hsiang Chang, PhD (886-4-22052121 ext. 4439, urology8395@yahoo.com.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
urothelial carcinoma (time frame: one year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jun 2011.
