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. The Be-Well Study is an NCI-funded collaborative, multi-center prospective cohort study, with NMID bladder cancer patients enrolled at Kaiser Permanente Northern (KPNC) and Southern California (KPSC) and bioassays performed at Roswell Park Cancer Institute (RPCI). 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 ascertained rapidly 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 RPCI. 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, 222 patients have completed the baseline interview, representing 78% male and 22% female, and 81% White, 7% Black, 5% Hispanic, 3% Asian, and 4% Other. Urine specimens have been collected from 82% of consented patients. Blood specimens have been collected from 85% of KPNC patients, and collection at KPSC began in November 2015. The 12-month follow-up interview and outcome ascertainment for disease recurrence and progression are scheduled to begin in February 2016. 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.
