Dr. Pienta is involved in research to define the tumor microenvironment of prostate cancer metastases, as well as developing new therapies for prostate cancer. Current research projects in the lab are studying why prostate cancer preferentially disseminate to the bone and can remain dormant for many years before returning to a proliferative phenotype that results in metastatic disease. Additionally, his research team is looking at ways to isolate, identify, and characterize these disseminated tumor cells so that new therapies can be designed to target them prior to becoming “reactivated” and metastatic.
