Abstract

It has been estimated that 184,500 new cases of prostate cancer (PRCA) will be diagnosed in the USA during 1998 and that 39,200 deaths will result from this disease. Thus, PRCA is the most commonly diagnosed malignancy, and the second leading cause of cancer-related death amongst American men. Our laboratory has investigated some of the unique biological characteristics of PRCA with the ultimate goal of formulating new, less invasive therapeutic strategies. We have recently hypothesized that epigenetic influences from adjacent stromal cells may be crucial in determining whether a particular prostate tumor remains dormant or becomes invasive (1). This hypothesis (Figure 1) suggests that subsequent to initial genetic damage to prostatic epithelium (PRE), signaling from epithelium to the surrounding stroma/mesenchyme (SM) cells becomes abnormal, resulting in dedifferentiation of SM towards a fibroblastic phenotype. One of the predicted consequences of such a change in differentiation state of SM is that the local microenvironment of the epithelium becomes altered, and thus the influence of stroma on epithelium changes from homeostatic to mitogenic. These changes subsequently lead to increased epithelial proliferation, migration and ultimately, to an increase in invasive potential of genetically altered prostatic epithelial cells.
