Abstract:
e296 Background: Bladder cancer is one of the top 10 incident cancers. Most cases (75%) are diagnosed as non-muscle invasive disease (NMID), yet NMID typically recurs (70%) and a subset (25%) progresses to muscle-invasive disease. Be-Well is a 5-year, NCI-funded prospective cohort study of NMID bladder cancer patients at Kaiser Permanente Northern (KPNC) and Southern California (KPSC). The goal is to examine diet and lifestyle factors and prognosis, with an emphasis on cruciferous vegetable (CV) intake and their unique isothiocyanate (ITC) content, the modifying effect of polymorphisms of ITC-metabolizing genes, and interactions with treatment. Our prior work suggests that dietary ITCs may prevent disease recurrence and progression in NMID patients. Methods: Newly-diagnosed patients with NMID (Ta, Tis, T1), who are English-speaking, KP members, and ≥ 21 years of age, are rapidly ascertained from electronic pathology reports and enrolled on average 2.6 months post-diagnosis. Baseline participation consists of a telephone interview including a food frequency questionnaire focused on CV intake, and providing blood and urine samples. Patients will be contacted for follow-up interviews and urine samples at 12 and 24 months. Smoking, medication use, occupational exposures, physical activity, quality of life, and urinary function are also queried. Biospecimens are processed and assayed at Roswell Park Cancer Institute. Strong support for Be-Well by KP urologists will promote dissemination of study results in patient care and recommendations. Results: Recruitment began in February 2015. To date, 159 patients have completed the baseline interview, representing 76% male and 24% female, and 80% White, 8% Black, 6% Hispanic, 3% Asian, and 3% Other. Urine specimens have been collected from 87% of consented patients. Blood specimens have been collected from 87% of KPNC patients, with collection at KPSC to begin in Fall 2015. Conclusions: The Be-Well Study is poised to be the largest and most comprehensive study to answer critical questions related to prognosis, quality of life, and care in patients diagnosed with early-stage bladder cancer.
