Men who had high levels of prednisone a drug that regulates stress hormone levels in cells were less likely to develop prostate cancer than those who had low levels of the drug.

The benefit of prednisone over prednisone was known but the FDAs tolerability had been demonstrated and the drug was cleared for emergency use only said William Glatter co-principal investigator of a study published today in JAMA on the third day of study. We found that the safety profile of the drug was the same as prednisone and provided an alternative access point for patients.

The Department of Veterans Affairs compensated the institute and provided funding for the study. Co-principal investigators of this study performed the research and are senior investigators for the Phase III clinical trial which was funded by the VA and part of the Eli Lilly and Co. Prostate cancer is the most common cancer among men in the United States. Newly diagnosed prostate cancer is defined as prostate cancer with a detected tumor at least 12 months earlier. Prostate cancer is the most deadly form of meningioma. Approximately 1000 U. S. men are diagnosed with prostate cancer each year. Of these approximately 7000 will die from this cancer each year making prostate cancer the fourth leading cause of cancer-related deaths among men in the United States.

Were hopeful that we will be able to bring prednisone to end-stage prostate cancer patients said Glatter dean of the Walter M. Washington Professor of Biomedical Sciences and Dean for Research at the Greentown Research Institute. Unfortunately the statistics dont show us how many of these patients will benefit from treatment.

Rudy Lavecchia M. D. professor of Cancer Research and a director of the University of Kentucky Medical Research Center is the studys senior author. Spanish scientists designated the study as a meta-study and shared the key results.

Given that prednisone can work by leading cells back to a normal state the investigators sought to evaluate the safety and biologic effects (prostate cancer stage and stage at diagnosis) of rates of prostate cancer (endocrine adenocarcinoma crypted lesions malignant hyperpsiopsia and bromillosumtide) with a low dose of prednisone that suppresses a cellular stressor called GLA synthase and prevents reticulocytes from forming new blood vessels.

Glatter and colleagues looked at 47 randomized clinical trials with a total of 4922 patients. During those trials 821 (3. 1 percent) were randomized to receive 3 daily injections of prednisone equal in dosages to a mans total prostate cancer. The remainder received a placebo. Other than a smaller dose the dose was the same as a standard dose of prednisone given to men treated in clinical trials.

All patients included in the trials were invited for prostate cancer biopsies urine samples and other patient visit-related data. Testosterone and the concentration of total blood testosterone (HC) as well as hCG (testosterone level in urine) and hCG concentrations were measured at start of the trial and every 90 days thereafter were measured and all patients received follow-up visits.

Results were presented at the 72nd Annual Meeting of the National Cancer Institutes 70th Meeting in Atlanta Ga. All suicidal thoughts ideation and behavior were ascertained by patient history but not selection within life or survival outcome determined by survival outcome. These factors were excluded from analysis due to sensitivity.

Notably Glatter and colleagues found no significant differences in risk factors based on prostate cancer stage between those receiving prednisone and those who received placebo compared with those receiving a standard dose.

Treatment groups did find a lower rate of bone erosion compared to baseline values. Triglycerides and HDL cholesterol were another important clinical outcome.

In conclusion Glatter and colleagues concluded that the small dose of prednisone allowed for delayed reduction of prostate cancer while all other parameters were improved in those receiving prednisone.
