Aborption and Metabolism of Lyophilized Black Raspberry Food Products in Men With Prostate Cancer Undergoing Surgery
Completed · Phase 1
Conditions studied: Stage I Prostate Cancer, Stage IIA Prostate Cancer, Stage IIB Prostate Cancer, Stage III Prostate Cancer
In brief
This Phase I/Ib trial is studying the absorption and metabolism of phytochemicals found in black raspberries in men undergoing surgery for prostate cancer. This knowledge will help us design future chemoprevention studies and assist in making future dietary recommendations for men at high risk for prostate cancer.
