GALVESTON, TEXAS -- A new research study leveraging a database
from the largest equal access health system in the US, the Department of Veteran Affairs offers insight into
the outcome of specific treatment patterns for advanced bladder cancer patients. Lead author Dr. Stephen
Williams of the University of Texas Medical Branch says it is one of the first comprehensive studies looking at
both the outcomes and the costs of treating a potentially lethal and devastating type of bladder
The study was published today in JAMA Network Open,
a medical journal focused on clinical care and healthcare innovation.
The study looked at the results of using
bacillus Calmette-Guérin (BCG) therapy for patients with high-risk non-muscle-invasive bladder cancer
(NMIBC). The analysis involved 412 high-risk NMIBC patients culled from a database of 63,139 patients
diagnosed with bladder cancer who had received more than one dose of BCG within VA centers across the United
States from Jan. 1, 2000, to Dec. 31, 2015.
“Studies like this are incredibly
important in allowing physicians to understand the effectiveness of a specific treatment and downstream
costs. It is particularly important when dealing with a cancer that is increasing in numbers over the last
three decades with a high mortality rate with advanced cases,” said Williams, who is Tenured Professor and
Chief of the pision of Urology as well as Director of Urologic Oncology at UTMB.
In addition, the study looked at the costs of treating bladder cancer for this same population. Bladder cancer has one of the highest lifetime treatment costs of all cancers. The cost of treating bladder cancer in the United States in 2020 approached
nearly $6 billion alone.
According to the study, total median costs
at one, two and five years from start of BCG induction were $29,459 ($14,991-$52,060), $55,267
($28,667-$99,846), and $117,361 ($59,680-$211,298), respectively. Patients who progressed had significantly
higher costs (5-yr, $232,729 median cost), with outpatient care, pharmacy, and surgery-related costs
contributing largely to the higher costs associated with disease progression.
“This study allowed us to determine where differences in treatment patterns led to differences in outcomes according to specific features of this disease. This is important as this group of patients is at increased risk of progression to advanced-stage
disease which is a deadly diagnosis. It also underscores the need for additional therapies to reduce the risk of disease progression and further improve outcomes,” Williams said.
In addition to Williams, authors included research collaborators
from Durham Veterans Affairs Health Care System in
Durham, NC, the Duke Cancer Institute Biostatistics Shared Resource, the Department of Surgery, Section of Urology, Augusta University
– Medical College of Georgia, Augusta, GA, Merck
& Co., Inc., and the Department of Urology and Center for Integrated Research on Cancer and Lifestyle at
Cedars-Sinai Medical Center in Los Angeles.
