OBJECTIVES Serum prostate specific antigen and digital rectal examination are the tests used as screening tests to detect prostate cancer. However, only approximately 30% of men with suspicion of cancer have it confirmed on prostate biopsy, and not all of these need treatment. Detection of circulating tumor cells in localized prostate cancer has given(More)
The presence of cells positive for cytokeratins or prostate-specific antigen (PSA) in bone marrow aspirates (BMAs) has been used to indicate the presence of micrometastasis. The aim of this prospective study of prostate cancer patients was to determine the presence of prostate cells in blood and BMAs and to compare them with bone marrow biopsy touch prep(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)
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)

Prostate cancer is the most commonly diagnosed cancer in men and the second leading cause of cancer deaths. The serum prostate specific antigen (PSA) is the only biomarker routinely used in screening. The aim of this study was to develop a system to test the presence of circulating prostate cells in men without a diagnosis of prostate cancer in relation(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)
INTRODUCTION HER-2 has been associated with castrate resistant prostate cancer and matrix metalloproteinase-2 (MMP-2) in the dissemination and invasion of tumor cells as well as activating angiogenesis. We present an immunocytochemical study of the effect of androgen blockade on the expression of HER-2 and MMP-2 in bone marrow micrometastasis and 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)
