Purpose : The objective of this study was to evaluate an immunoassay for urinary
nuclear matrix protein (NMP22) as an indicator for transitional cell carcinoma of the
bladder.
Materials and Methods : Three groups of subjects attended the trial of NMP22. First
group was 27 patients with transitional cell carcinoma of the bladder, second group was
24 patients with other urinary cancer consisted of prostate cancer and renal cell
carcinoma, and third group was 24 healthy volunteers. NMP22 was determined using a
commercial test kit, which is based on an enzyme-linked immunosorbent assay.
Results : In normal healthy volunteers and other urinary cancer group median NMP22
levels were 2.24 and 3.27 U/§¢, respectively. Median urinary NMP22 levels in patients
with transitional cell carcinoma of the bladder were 54.30 U/§¢. It was significantly
greater than other two groups. Median NMP22 levels according to the tumor stage and
the tumor grade did not show the significant difference statistically.
Conclusions : Urinary NMP22 is a useful marker that is more specific for bladder
cancer than for other urinary cancer. Further tests are required to clarify the influence
of other specific conditions, such as urinary tract infection, and intravesical drug
instillation or procedure.
