This phase I trial investigates how well a healthy eating program works in improving outcomes in patients with bladder cancer. The behavioral dietary program consists of educational materials, live phone calls, and interactive voice response phone messages. Participating in the healthy eating program may improve eating habits and/or reduce the risk of bladder cancer from coming back.
I. Develop an evidence-based behavioral intervention to increase cruciferous vegetable
intake, with the goal of attaining desirable urinary isothiocyanates (ITC) levels effective
for anti-cancer activities.
II. Conduct a feasibility pilot of our dietary behavioral intervention through a hybrid I
implementation randomized controlled design in 80 non-muscle invasive bladder cancer (NMIBC)
survivors, where the treatment group (n=40) will receive an evidence-based telephone
intervention to increase cruciferous vegetable intake and the control group (n=40) will
receive a general fruit and vegetable intake intervention based on National Cancer Institute
I. To ascertain the level of gene expression changes in urinary exfoliated epithelial cells
(due to the intervention) as a surrogate for intermediate efficacy.
I. Engage the clinical care providers of patients enrolled in our intervention to ascertain
the barriers and facilitators of intervention implementation within clinical practice through
conducting 20 semi-structured interviews.
AIM I: Develop an evidence-based behavioral intervention using a systematic process
consisting of information gathering, discussion groups, and mock intervention delivery.
AIM II: Patients are randomized to 1 of 2 arms.
ARM A (HEALTHY EATING PROGRAM A): Patients receive mailed educational materials about the
importance of consuming cruciferae, setting healthier eating goals, and the importance of
keeping track of what they eat. Patients also receive one phone call from study staff to make
sure they understood the educational materials received and 11 interactive voice response
(IVR) phone messages over 6 months.
ARM B (HEALTHY EATING PROGRAM B): Patients receive mailed educational materials about general
fruit and vegetable intake, setting healthier eating goals, and the importance of keeping
track of what they eat. Patients also receive one phone call from study staff to make sure
they understood the educational materials received and 11 IVR phone messages over 6 months.
