Translational research takes important findings from the laboratory to the clinic and back to the laboratory, with the ultimate goal of improving patient care.
Duke Urology translational teams are committed to discovering and improving upon therapies and outcomes for men with prostate cancer.
The Polascik research group is focused on the following areas of investigation related to prostate cancer:
- The development and integration of prostate imaging and image-guided focal therapy for early stage prostate cancer
- Improving prostate cancer outcomes including cancer control, potency and continence using minimally invasive therapies such as cryosurgery and low energy direct current
To further their research, the group has formed intramural multidisciplinary research groups for prostate imaging/therapy through the Duke Cancer Institute involving urologic oncology, radiology, genitourinary pathology, biomedical engineering, and medical oncology.
Translational Research Initiatives
Current research initiatives include:
- Development of a new imaging modality—acoustic radiation force impulse—a type of ultrasonography that uses tissue stiffness to characterize cancerous regions within the prostate. We have an ongoing R-01 National Institutes of Health grant to study and develop this technology, which we hope will one day guide prostate biopsy and treatment to focal cancer lesions.
- Development of adjunct agents to increase cellular kill using cryosurgery. At present, we have a mutual collaboration with a basic science in-vitro laboratory regarding the use of vitamin D as the adjunct in an in-vitro and in-vivo model.
- Studying low energy direct current as a means to target and ablate prostate cancer while preserving erection in the canine model.
- Development of an animal model to study the effect of prostate cancer treatment on erectile function.
