title: Prostate-specific antigen changes before and after administration of an angiogenesis inhibitor (tnp-470).
abstract: A 61-year-old man with progressive prostate cancer after initial hormonal therapy was treated with TNP-470, an experimental agent with potent antiangiogenesis properties. During the period of TNP-470 treatment, the concentration of serum prostate-specific antigen (PSA) rapidly increased from 28.4 to 89.9 ng/ml. After termination of TNP-470 therapy, the concentration of PSA decreased from 89.9 to 10.3 ng/ml. This pattern of PSA change was previously unanticipated and may eventually provide additional insight into the pharmacological actions of TNP-470.
