Materials and Methods Seventeen patients with 2 successive rises in PSA after failure of standard local therapy were treated with 5 000 mg of VC and 50 mg of VK3 each day for a period of 12 weeks. Prostate Specific Antigen PSA levels PSA velocity PSAV and PSA doubling times PSADT were calculated before and during treatment at 6 week intervals. Following the initial 12 week trial 15 of 17 patients opted to continue treatment for an additional period ranging from 6 to 24 months. PSA values were followed for these patients. Results At the conclusion of the 12 week treatment period PSAV decreased and PSADT increased in 13 of 17 patients p . There were no dose-limiting adverse effects. Of the 15 patients who continued on Apatone after 12 weeks only 1 death occurred after 14 months of treatment. Conclusion Apatone showed promise in delaying biochemical progression in this group of end stage prostate cancer patients.
