The Contractor shall provide computer-related technical support services, primarily systems design, computer programming, system documentation and operational support to the Biometry Research Group, Division of Cancer Prevention, in the National Cancer Institute, the National Institutes of Health. The computer-related support falls into three main categories: data management, systems design and development and statistical analysis and modeling. One of the projects for which the Contractor will provide support is the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial, or PLCO, which is a large-scale clinical trial to determine whether certain cancer screening tests reduces deaths from these cancers. The underlying rationale for the trial is that screening for cancer may enable discovery and treatment of the disease earlier. The cancer prevention aspect is related to the design that tests whether the introduction of screening reduces mortality. The screening studies for these four cancers can be considered as four separate projects for description purposes. The screening studies for colon cancer have as the objective to evaluate the ability of colon cancer screening tests to reduce deaths from one of the four cancers in the PLCO study. There are 75,000 men and 75,000 women participating in the PLCO study who are at normal risk for developing colon cancer. Participants are randomly assigned to one of two groups, the intervention group or the control group. The intervention group receives: PSA (men only), at initial visit and annually for 5 years Digital rectal exam (men only), at initial visit and annually for 3 years Flexible sigmoidoscopy, at initial visit and after 5 years in study (colon cancer screening) Chest X-ray: smokers had test at entry and annually for 3 years. Never smokers had the test at entry and annually for 2 years. CA-125 blood test (women only), at initial visit and annually for 5 years Transvaginal ultrasound (women only), at initial visit and annually for 3 years The control group receives usual care. Note that these are randomized controlled trials where the endpoints are designed to test whether the introduction of screening reduces mortality from the particular cancer in question.

承包商应提供计算机相关的技术支持服务，主要是系统设计、计算机编程、系统文档和操作支持，以生物测量研究组，癌症预防部，在美国国立卫生研究院的国家癌症研究所。与计算机有关的支持主要分为三类：数据管理、系统设计和开发以及统计分析和建模。
