Dr. Sfanos and her lab study the cellular and molecular pathology of prostate disease. She is specifically interested in agents that may lead to chronic inflammation in the prostate. Ongoing studies in the lab are aimed at understanding the influence of prostate infections and inflammation on prostate disease including prostate cancer and benign prostatic hyperplasia (BPH). The laboratory also focuses on the influence of the microbiome on prostate cancer development, progression, and/or treatment.
Dr. Sfanos’ previous studies have demonstrated the presence of multiple microbial species in the prostate of cancer patients and, importantly, many of the organisms identified are consistent with genera associated with inflammation-associated conditions including bacterial prostatitis or urinary tract infections. She works very closely with both genitourinary pathologists as well as epidemiologists in an effort to correlate discoveries in the laboratory with prostate cancer risk as well as disease pathology.
