INTRODUCTION HER-2 expression in prostate cancer is associated with a worse prognosis and is suggested to play a role in androgen resistance. We present a study of HER-2 expression in circulating tumor cells and micrometastasis in bone marrow and the effect of androgen blockage or DES in the presence of HER-2 expressing cells. PATIENTS AND METHODS A(More)
Introduction. Developments in immunological and quantitative real-time PCR-based analysis have enabled the detection, enumeration, and characterization of circulating tumor cells (CTCs). It is assumed that the detection of CTCs is associated with cancer, based on the finding that CTCs can be detected in all major cancer and not in healthy subjects or those(More)
INTRODUCTION Although 90% of prostate cancer is considered to be localized, 20%-30% of patients will experience biochemical failure (BF), defined as serum PSA >0.2 ng/mL, after radical prostatectomy (RP). The presence of circulating prostate cells (CPCs) in men without evidence of BF may be useful to predict patients at risk for BF. We describe the(More)
This workshop is the result of a practice-based research, which explored several interrelated elements: first the theory of Psychogeography, ap- plied to the creative representation of urban environments from a multi- layered approach and from an emotional and psychological perspective; second, the exploration of sound and acoustic theory, as research tools(More)
INTRODUCTION PSA parameters have been used in an attempt to improve the diagnostic yield of prostate screening tests; the detection of primary malignant circulating prostate cells (CPCs) may improve the diagnostic yield of screening and therefore avoid unnecessary biopsies. PATIENTS AND METHODS Prospective study of all men undergoing initial prostate(More)
