title: Development of angiogenesis inhibition as therapy for prostate cancer.
abstract: Angiogenesis is essential to prostate cancer progression. The first study of antiangiogenic therapy in patients with locally advanced prostate cancer at The University of Texas M. D. Anderson Cancer Center showed that preoperative treatment with a fumagillin analog was safe. Microvascular density correlated with Gleason score, but marked intertumoral and intratumoral changes were observed. Clinical experience with thalidomide (Thalomid), which inhibits angiogenesis induced by both vascular endothelial growth factor and basic fibroblast growth factor, has included observation of "clinical improvement" in patients with androgen-independent prostate cancer and anecdotal responses in patients with metastatic disease refractory to chemotherapy. In an effort to assess the in vivo effect of thalidomide in prostate carcinoma, we have initiated a study of neoadjuvant thalidomide treatment in patients with locally advanced prostate cancer that is to include serial ultrasonographic and pathologic evaluation, as well as serial collection of serum/urine markers that may prove useful surrogate markers of antiangiogenic activity. We have also initiated a phase I/II trial of thalidomide, paclitaxel (Taxol), and estramustine (Emcyt) in patients with metastatic androgen-independent prostate cancer progressing after up to two courses of chemotherapy.
