According to the study's lead author, Dr. Moshe Shike, Director of Memorial Sloan-Kettering's Cancer Prevention and Wellness Program, the failure of diet to influence PSA levels over a relatively short period of time should not be viewed as definitive evidence that diet does not have a preventative effect on prostate cancer.
"This is a rigorous and randomized study that provides valuable data which previously did not exist," says Dr. Shike. "However, we need to consider the impact of a healthy diet over a longer period of time and determine if diet influences the occurrence and growth of prostate cancer without drastically affecting levels of PSA – which is only a surrogate marker for prostate cancer."
The study is being published in the September 1 issue of the Journal of Clinical Oncology.
