UroSEEK may Help Diagnose Urothelial Cancer Early

UroSEEK could help diagnose urothelial cancers of both bladder, and upper urinary tract more accurately finds a new study. UroSEEK is the new non-invasive method devised to detect both bladder and upper urinary tract cancer.

The findings of this study are published in eLife journal. Urothelial cancers are among the most costly cancers to treat in the United States. Now an international team of cancer researchers including Kate Dickman, Ph.D., of the Department of Pharmacological Sciences and Medicine/Nephrology at Stony Brook University School of Medicine has developed a highly sensitive and specific non-invasive test as a biomarker for early detection of urothelial cancers.

Gall Bladder Cancer Rates Decline in Men, Late-Stage Diagnosis on the Rise
Gallbladder cancer rates have steadily decreased in men since 1973 but there has been an increase of the incidence of late-stage gallbladder cancer.

‘Among 570 patients at risk for bladder cancer, UroSEEK tested positive 83 percent of those who really did develop bladder cancer. The detection rate increased to 95 percent when urine cytology and UroSEEK were used in combination.’

UroSEEK identifies genetic errors in cells shed into the urine. The analysis scans for mutations in 11 cancer driver genes associated with urinary tract cancer and for evidence of chromosomal imbalance.

In the study, the researchers found that of 570 patients at risk for bladder cancer, UroSEEK tested positive in 83 percent of those who developed bladder cancer. The detection rate increased to 95 percent when urine cytology and UroSEEK were used in combination.

They found also that of 56 patients with upper tract urothelial cancer, 75 percent tested positive by UroSEEK. In the future, the researchers say, UroSEEK will be applied to large patient populations to screen for bladder and upper urothelial cancer.

Nano-Chemo Particle Developed to Treat Bladder Cancer
Nano-chemoparticles increase absorption of the drug into the bladder without being diluted by urine production and stay within the bladder to better attack tumors.

The research involved the joint efforts and multidisciplinary expertise of urologists, cancer biologists, pharmacologists, pathologists, oncologists, chemists and computational biologists from around the world.

Funding for the research was provided by Henry and Marsha Laufer; the National Science Council (Taiwan); National Institutes of Health; John Templeton Foundation; Conrad N. Hilton Foundation; Ludwig Institute for Cancer Research, and the Sol Goldman Pancreatic Research Foundation. The findings of //

Alternative Strategy to Administer Antibody-Based Immunotherapy to Treat Bladder Cancer
The alternative administration of a drug to the tumor results in fewer adverse events in patients, as compared to injections into the blood stream.
