Cancer control is the reduction of cancer incidence, morbidity, or mortality through an orderly sequence from research on interventions to systematic application of the results to populations. To help ensure this progression, a system of classifying cancer control research into phases has been developed. These phases are hypothesis development, studies of methods, case-control studies, defined population studies, and demonstration-implementation. Studies of the potential impact of cancer control measures in defined populations are particularly needed. New research support should therefore be provided to research units focusing on this area of cancer control. A new community clinical oncology program will link community physicians with cancer center and university scientists in a cooperative cancer control effort. Another new cancer control program is called chemoprevention research, that is, clinical trials aimed at determining whether selected micronutrients or synthetic compounds can reduce the incidence of cancer.
癌症控制是指通过从干预措施研究到将研究结果系统应用于人群的有序过程，降低癌症发病率、发病率或死亡率。为了帮助确保这一进展，已开发出一种将癌症控制研究分为不同阶段的系统。这些阶段包括假设形成、方法研究、病例对照研究、特定人群研究以及示范实施。尤其需要对特定人群中癌症控制措施的潜在影响进行研究。因此，应向专注于这一癌症控制领域的研究单位提供新的研究支持。一个新的社区临床肿瘤学项目将把社区医生与癌症中心和大学科学家联系起来，共同开展合作性癌症控制工作。另一个新的癌症控制项目称为化学预防研究，即旨在确定某些微量营养素或合成化合物是否能降低癌症发病率的临床试验。
