Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The North Carolina-Louisiana Prostate Cancer Project is a population-based case-only study of over 2,000 men newly diagnosed with prostate cancer designed to address racial differences in prostate cancer aggressiveness and survival through a comprehensive evaluation of social, individual, and tumor level influences on prostate cancer aggressiveness. Project 3 specifically aims to examine nutritional modulation of prostate cancer aggressiveness using dietary assessment and biomarker-based data on dietary factors.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A total of 2,258 (1,130 African Americans and 1128 European Americans) men newly diagnosed with prostate cancer in North Carolina and Louisiana were enrolled into the study between 2004 and 2009. Participants signed informed consent and were interviewed by a trained nurse who collected information on demographics, occupation, family history, health status, health care, prostate cancer diagnosis and screening history, medication use, anthropometrics, lifestyle factors (e.g., physical activity, smoking), and diet and supplement use. Research subjects were asked to recall their diet in the year prior to prostate cancer diagnosis via a modified version of the National Cancer Institute Diet History Questionnaire. Vitamin and supplement use in the year prior to prostate cancer diagnosis was assessed via a validated questionnaire, and current use was assessed by bottle label inventory. Blood, urine, and adipose tissue samples were collected.
