Genetic Susceptibility to Bladder Cancer - Full Text View

Sponsor:	Baylor College of Medicine
Collaborator:	M.D. Anderson Cancer Center

ClinicalTrials.gov Identifier:	NCT00848289

Purpose

Bladder cancer (BC) is a model disease system for evaluating the relationship of tobacco, dietary, and occupational exposures (which are responsible for up to 90% of BCs) and host-specific susceptibility factors. The induction of BC by arylamines (from tobacco or occupational exposure) is one of the best understood types of carcinogenesis. There is also substantial evidence suggesting that an individual's genetic make-up influences susceptibility to cancer.

This clinical research study will identify biologic and lifestyle factors which increase a person's risk of developing specific cancer. We propose to conduct a case-control study examining interindividual differences in susceptibility to tobacco carcinogenesis as predictors of bladder cancer risk. We will measure susceptibility to tobacco carcinogenesis and this will include studies of the genetic modulation of carcinogen activation and detoxification and of chromosome sensitivity to tobacco mutagens.

Further study details as provided by Baylor College of Medicine:

Primary Outcome Measures:

To assess both cohorts, two mutagen sensitivity susceptibility assays that quantifies the number of lymphocytic chromatid breaks induced by in vitro exposure to bleomycin and the number of breaks induced by in vitro exposure to a tobacco carcinogen. [ Time Frame: After last subject has completed the study ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

To determine in both cohorts, the frequencies of polymorphisms in those genes that regulate the metabolism of carcinogens in tobacco smoke. [ Time Frame: After the last subject completes the study ] [ Designated as safety issue: No ]
To explore the associations between the cytogenetic, molecular components and epidemiologic covariates (age, sex, ethnicity, cigarette smoking status, alcohol use, dietary intake, and family history of cancer) in risk of bladder cancer. [ Time Frame: After the last subject has completed the study ] [ Designated as safety issue: No ]

Biospecimen Retention: Samples Without DNA
