Cancers of the prostate and bladder are among the most common types of genitourinary cancers. It is estimated that nearly 13% of all new cancers diagnosed in 2015 will be of the prostate, and another 5% will be bladder cancers.1
Optimal management of prostate cancer minimizes unnecessary procedures and treatments for patients with indolent disease. Despite diagnostic gains, about 25% of men with indolent, nonfatal prostate cancer are still overtreated.2 Recent advances in personalized cancer testing are helping reduce that number. The Prostate Health Index (PHI) uses enzyme assays of 3 forms of prostatespecific antigen (PSA) to predict the risk of aggressive disease3 , and the kallikrein panel (4k-panel) uses 4 enzyme assays combined in an algorithm with clinical parameters. The kallikrein panel (4k-panel) has been found to add value in tests for prostate cancer.4
When biopsy is indicated, MRI-guided prostate biopsy with transrectal ultrasound fusion represents the latest technological advance. MRI and transrectal ultrasound images are fused to produce a 3-dimensional reconstruction of the prostate, allowing for improved lesion detection. The targeted biopsies have been found to be significantly more sensitive for detecting prostate cancer.5 The procedure can be performed under local anesthesia on an outpatient basis.
Nearly 80% of patients who initially present with bladder transitional cell carcinoma have non-muscle-invasive bladder tumors. 6 Traditionally, white-light cystoscopy has been used to detect non-muscle-invasive bladder cancer; however, more recently blue-light cystoscopy (Cysview®) has gained use. Cysview combines the tumor photosensitizer hexaminolevulinate with blue-light cystoscopy to improve bladder tumor detection and to facilitate more complete resection, thereby reducing the risk of residual tumor and lessening the rates of recurrence.7
See a brief video presentation on fluorescent (blue light) cystoscopy. University of Minnesota Health surgeon Badrinath Konety, MD, describes the diagnostic tool's use.
University of Minnesota Medical Center’s Institute for Prostate and Urologic Cancers is one of the few centers in the United States with the expertise, technology, and volume necessary to allow for the successful use of these advanced techniques in genitourinary cancer diagnosis. In the last year, our Cancer Care team has performed over 100 MRI biopsy procedures for prostate cancer, and we remain one of the only centers in Minnesota offering Cysview for bladder cancer.

Biopsies on a patient with a history of obstructive urinary symptoms and rising PSA levels produced only negative results. Using a new MRI-ultrasound technology, surgeons were able to locate lesions and successfully treat for prostate cancer.Continue reading
University of Minnesota Cancer Care has announced a clinical trial to test the proposition that MRIs of a higher 7-Tesla field strength will provide increased sensitivity to prostate cancer metabolic markers that are not detectable at lower-field strengths.Continue reading
