DESCRIPTION (provided by applicant): Effective control of a complex disease such as breast cancer requires a multidisciplinary approach that bridges the gap between the "why and what" of cancer causation and the "how" to prevent cancer incidence morbidity and mortality. This Preventive Oncology Academic Award will provide the candidate the opportunity to strengthen her skills in clinical trial design and biostatistics, develop her knowledge in molecular biology, pharmacology and toxicology and give her the necessary research experience to successfully integrate a multidisciplinary approach into the design of effective chemoprevention strategies. The candidate will attend courses offered at Johns Hopkins as well as the National Cancer Institute (NCI) focusing on clinical trial design and the use of biomarkers in epidemiological and clinical research. She will participate in conferences, rounds and seminars both in the Department of Epidemiology and in the Oncology Center. She will also engage in a limited amount of teaching and clinical oncology work relevant to her cancer prevention activities. In keeping with the candidates goal to become proficient in the design, conduct and analysis of intervention trials two clinical studies are proposed to examine the efficacy of an aqueous extract of broccoli sprout or "tea" (BST) as a chemopreventive agent for breast cancer. The first study evaluates the pharmacokinetics and pharmacodynamic action of broccoli sprouts tea in 30 healthy women undergoing breast reduction surgery by conducting a two-week dose-finding clinical trial that measures both phase 2 inducer activity and isothiocyanate metabolites in mammary tissue. In the second study, a phase II randomized trial design will be used to test whether a 3 months intervention of BST modulates a panel of specific tissue biomarkers of breast cancer risk compared to placebo, in 126 women at increased risk for breast cancer. Together these planned developmental experiences along with the supportive environment and research infrastructure of Johns Hopkins and the mentorship of Dr Kathy Helzsouer and Dr Nancy Davidson will ensure Dr Visvanathan's successful transition into an independent cancer prevention and control investigator with expertise in chemoprevention trials.

描述（由申请人提供）：有效控制乳腺癌等复杂疾病需要多学科方法，以弥合癌症病因的“原因和内容”与预防癌症发病率、发病率和死亡率的“如何”之间的差距。该预防肿瘤学学术奖将为候选人提供机会，加强她在临床试验设计和生物统计学方面的技能，发展她在分子生物学，药理学和毒理学方面的知识，并为她提供必要的研究经验，以成功地将多学科方法整合到有效的化学预防策略的设计中。候选人将参加约翰霍普金斯和国家癌症研究所（NCI）提供的课程，重点是临床试验设计和流行病学和临床研究中生物标志物的使用。她将参加流行病学系和肿瘤中心的会议、圆桌会议和研讨会。她还将从事与她的癌症预防活动相关的少量教学和临床肿瘤学工作。在保持与候选人的目标，成为精通干预试验的设计，进行和分析两个临床研究提出了检查西兰花芽或“茶”（BST）的水提取物作为乳腺癌的化学预防剂的功效。第一项研究评估了西兰花芽茶在30名接受乳房缩小手术的健康女性中的药代动力学和药效学作用，通过进行为期两周的剂量探索临床试验，测量乳腺组织中的2期诱导剂活性和异硫氰酸酯代谢物。在第二项研究中，将使用II期随机试验设计来测试与安慰剂相比，BST的3个月干预是否调节了126名乳腺癌风险增加的女性中乳腺癌风险的一组特定组织生物标志物。这些有计划的发展经验与约翰霍普金斯的支持性环境和研究基础设施以及Kathy Helzsouer博士和Nancy Davidson博士的指导一起沿着，将确保Visvanathan博士成功转变为具有化学预防试验专业知识的独立癌症预防和控制研究人员。
