WASHINGTON — Bladder cancer is relatively common and imposes the highest per patient cost on the U.S. health care system than the management of any other cancer type. Now, a new test could be key to reducing the cost of care while at the same time, relieving some patients of unneeded over-treatment, say investigators led by Georgetown Lombardi Comprehensive Cancer Center researchers.

Deciding whether to treat bladder cancer aggressively has been difficult — predictive diagnostic data is limited.  Up to 70 percent of patients treated for early stage lesions that have not invaded the bladder wall will experience recurrence of these lesions, and 20 percent of these patients will develop an invasive cancer. 

Because clinicians do not know which tumors will become dangerous, they err on the side of caution and perform an extremely intensive post-surgery surveillance regimen, including cystoscopy (a lighted optical scope that examines the inside of the bladder) as frequently as every three months for two years after removal of the tumor, and every 6-12 months for the years after.

The Georgetown-led investigators offer a new solution to the dilemma. They have found that a fairly simple test that significantly improves the identification of bladder tumors that will likely become invasive.

The study, published in Clinical Cancer Research, “validates this test that helps predict whether an early stage bladder cancer will recur and progress,” says the study’s senior author, Todd Waldman, MD, PhD, a professor of oncology at Georgetown.

Working with researchers from the U.S. and Denmark, Waldman has found that, compared with using current diagnostic procedures, the new test is 2.4 times more accurate in identifying tumors likely to recur after treatment, and 1.9 times more accurate at predicting which tumors will likely to progress, invade the bladder wall and spread.

The test involves examining bladder tumors that had been removed during initial surgery for over expression of the STAG2 gene, which Waldman earlier identified as key to development of potentially deadly bladder tumors.

Checking for STAG2 is a “very simple and very robust” procedure for pathologists who routinely examine excised tumors, Waldman says. His studies have described how to run this test.

Using the test could, in some cases, spare patients constant surveillance and, in others, support forgoing aggressive treatment that can produce significant side effects, the researchers say.

So Waldman and his colleagues have worked on a diagnostic test for years. This study summed up several of those clinical studies, concluding that using the test “offers additional two-fold predictive discrimination,” Waldman says.

“We are closer to our goal of lowering the risk of both aggressive bladder cancer and over-surveillance and treatment side effects in bladder cancer patients,” he says. “In principle, it might be possible to reduce the frequency of post-resection surveillance and therapy in patients whose cancer is STAG2-negative, and, conversely, treat patients and keep up high frequency surveillance in patients who have positive test results.”
