Using specialized equipment needed, physicians at UT Southwestern Medical Center’s Harold C. Simmons Comprehensive Cancer Center began using the fusion biopsy procedure about three years ago for its ability to blend live ultrasound images with captured MRI images. The fused image creates the 3D model, and flags anomalies that could be areas of concern. That helps guide urologists to get tissue samples called biopsies to determine whether cancer is present.
UT Southwestern’s early adoption of the cutting-edge technology allowed researchers to report on the superior diagnostic performance of this novel approach compared to traditional methods for diagnosing prostate cancer. Furthermore, these researchers have partnered with colleagues in Brazil to conduct follow up studies that now show the technique consistently improved detection of clinically significant prostate cancer under a wide variety of conditions, even when radiologists were using different equipment and protocols.
“In the past, we diagnosed prostate cancer by random biopsies of the prostate in men with elevated PSA values. With fusion biopsy, we actually find more cancer, we can differentiate between dangerous tumors and less aggressive tumors, and in some cases we perform fewer biopsies,” said Dr. Daniel Costa, Assistant Professor of Radiology and with the Advanced Imaging Research Center (AIRC) at UT Southwestern.
Prostate cancer is the second most common cancer diagnosed in men, after skin cancer. Prostate cancer risk increases with age, with most cases occurring after age 60. According to the National Cancer Institute (NCI), about 180,890 men will be diagnosed this year, and about 14 percent of men will be diagnosed sometime during their lifetime.
