DESCRIPTION (provided by applicant): Bladder cancer is one of the top ten most common cancers in the U.S., contributing to over 60,000 new cases and 10,000 deaths annually. The majority of cases (70-80%) are diagnosed at early stage (termed "non-muscle invasive"), yet the cancer typically recurs (50-80%), with a subset further progressing to muscle- invasive disease with poor survival. Due to this markedly high recurrence and progression, patients are followed intensively by cystoscopy with repeat transurethral manipulation, making bladder cancer one of the most costly diseases. Cruciferous vegetable intake has been associated with reduced risk of primary bladder cancer and improved survival, which might be partly attributable to their unique phytochemical isothiocyanates (ITCs). Dietary ITCs are promising chemopreventive agents with multi-faceted anti-cancer mechanisms. Our prior in vitro, in vivo, and epidemiologic studies strongly support dietary ITCs and ITC-rich cruciferous vegetables playing a key role in preventing bladder cancer recurrence and progression and improving prognosis. Above all, via metabolic pathways in humans, orally ingested ITCs are rapidly delivered to the bladder and concentrated in the urine, rendering bladder cancer the best target for their anti-cancer activities. This application requests to conduct a new prospective cohort study of 1,811 newly diagnosed non- muscle invasive bladder cancer patients in the Kaiser Permanente Northern California (KPNC) and Southern California (KPSC) Medical Care Programs. Our goal is to comprehensively examine the role of cruciferous vegetable intake, in conjunction with genetic polymorphisms related to ITC metabolism, in potentially reducing disease recurrence and progression, and increasing the efficacy of intravesical treatment. We propose to investigate: 1) the associations between cruciferous vegetable intake and bladder cancer recurrence and progression; 2) the modifying effect of polymorphisms of ITC-metabolizing genes on the associations between cruciferous vegetable intake and bladder cancer recurrence and progression; and 3) the effects of the interactions between cruciferous vegetable intake and therapeutic agents on bladder cancer recurrence and progression. Furthermore, we propose to establish the largest prospective cohort of non-muscle invasive bladder cancer patients with longitudinal questionnaire data and banked biospecimens for further future research of bladder cancer outcomes including survival and quality of life. Bladder cancer is an extremely understudied disease considering its disproportionate high incidence and recurrence, high cost of clinical management, and significant impact on quality of life. The proposed study within one of the largest U.S. integrated health care settings will be the first to investigate the role of dit in recurrence and progression of the disease, with genetic profiles taken into consideration to identify those who will benefit most. Considering the wide availability of cruciferous vegetables in the U.S., this study could have an immediate impact on bladder cancer prognosis.

描述（由申请人提供）：膀胱癌是美国十大最常见的癌症之一，导致每年超过6万例新病例和1万例死亡。大多数病例（70-80%）在早期阶段（称为“非肌肉侵入性”）被诊断，然而癌症通常复发（50-80%），其中一个子集进一步进展为具有较差存活率的肌肉侵入性疾病。由于这种明显的高复发率和进展，患者需要进行膀胱镜检查并重复经尿道操作，使膀胱癌成为最昂贵的疾病之一。十字花科蔬菜的摄入与原发性膀胱癌的风险降低和生存率提高有关，这可能部分归因于其独特的植物化学物质异硫氰酸酯（ITC）。膳食ITC是具有多方面抗癌机制的有前途的化学预防剂。我们先前的体外，体内和流行病学研究强烈支持饮食ITC和富含ITC的十字花科蔬菜在预防膀胱癌复发和进展以及改善预后方面发挥关键作用。最重要的是，通过人体的代谢途径，口服摄入的ITC被快速递送到膀胱并浓缩在尿液中，使膀胱癌成为其抗癌活性的最佳靶点。 本申请要求在Kaiser Permanente北方加州（KPNC）和南加州（KPSC）医疗护理项目中对1，811例新诊断的非肌层浸润性膀胱癌患者进行一项新的前瞻性队列研究。我们的目标是全面研究十字花科蔬菜摄入量的作用，结合与ITC代谢相关的遗传多态性，在潜在地减少疾病复发和进展，并增加膀胱内治疗的疗效。我们建议调查：1）十字花科蔬菜摄入与膀胱癌复发和进展之间的关联; 2）ITC代谢基因多态性对十字花科蔬菜摄入与膀胱癌复发和进展之间的关联的修饰作用;以及3）十字花科蔬菜摄入与治疗剂之间的相互作用对膀胱癌复发和进展的影响。此外，我们建议建立一个最大的前瞻性队列的非肌层浸润性膀胱癌患者的纵向问卷调查数据和库存生物标本，为进一步的未来研究膀胱癌的结果，包括生存和生活质量。 膀胱癌是一种研究非常不足的疾病，因为它的发病率和复发率不成比例，临床管理成本高，对生活质量有重大影响。在美国最大的综合医疗保健机构之一进行的拟议研究将是第一个调查dit在疾病复发和进展中的作用的研究，并考虑到遗传特征，以确定那些受益最大的人。考虑到十字花科蔬菜在美国的广泛供应，这项研究可能对膀胱癌的预后产生直接影响。
