Although intensely studied, the molecular and biochemical determinants of prostate cancer development and progression remain ill-defined. Moreover, current markers and methodologies cannot distinguish between a tumor that will remain indolent and not impinge on patient survival, versus a tumor with aggressive traits culminating in metastatic spread and death. Once prostate cancer is confirmed the most significant threat to a patient's survival and quality of life involves tumor metastasis. Radical surgery notwithstanding, prostate cancer accounts for 10% of all cancer-related deaths primarily arising through development of metastasis. Metastasis markers demonstrating an acceptable level of reliability are an obvious necessity if disproportionate and costly treatment is to be avoided and a reasonably accurate determination of clinical prognosis and measure of successful response to treatment is to be made. Therapeutic strategies that specifically inhibit metastatic spread are not presently possible and may not become available in the immediate future. This is because, while localized tumorigenesis has been relatively amenable to detection, analysis and treatment, metastasis remains a relatively undefined, complex and underexplored area of prostate cancer research. New findings in the field such subclasses of genes called metastasis suppressors and cancer progression suppressors, have opened up exciting avenues of investigation. We review current methodological approaches, model experimental systems and genes presently known or having potential involvement in human prostate cancer metastasis. (C) 2001 Wiley-Liss, Inc.
