ABSTRACT
Objective To investigate the diagnosis value of mucin 7 in plasma and urine in the detection of bladder cancer.Methods Expression of mucin 7 was detected quantitatively in plasma and urine from 23 patients with bladder cancer and 23 patients as control group by enzyme-linked immunosorbent assay(ELISA) from November 2012 to September 2013.There were 15 were male and 8 were female in the 23 bladder cancer patients,aged from 41 to 95 years,with an average of 64 years.Of the 23 bladder cancer pathology,12 with high grade,11 with low grade,11 with invasive disease and 12 with noninvasive disease.There were 19 males and 4 females in the 23 patients in control group,aged from 28 to 85 years,with an average of 61 years.Results The amount of mucin 7 in plasma was significantly higher in bladder cancer group than that in control group [(7.43±4.54) ng/ml versus (4.55±.1.98) ng/ml,P=0.017].While there was no significant difference in urine between the two groups [(12.44±7.1 1) ng/ml versus (11.96±8.41)ng/ml,P=0.840].There was no significant differences in the amount of mucin 7 had in different grades and stages of bladder cancer (P＞0.05).Conclusions Expression of mucin 7 in plasma of patients with bladder cancer is significantly higher than that in control group.Mucin 7 expression has no significant correlation with the grading and staging of bladder cancer.Detecting mucin 7 expression quantitatively with ELISA for diagnosis of bladder cancer is a method with certain value.
ABSTRACT
Objective To compare the sensitivity and specificity of mucin 7(Muc7) mRNA test with urine cytology in detection bladder cancer.Methods In 86 patients suspected with bladder cancer,RT-PCR for Muc7 mRNA and urine cytology were conducted in the same urine samples.Fif-ty-two patients with bladder transitional cell carcinoma were confirmed histologically.The sensitivity and specificity of Muc7 mRNA and urine cytology were analyzed.Results The overall sensitivity,specificity and false positive of Mue7 mRNA test were 84.6%,85.2% and 14.7% respectively.Those of urine cytology were 34.6%,91.2% and 8.8% respectively.There were no significant differences between urine cytology and Muc7 mRNA test in the specificity and false positive; however,Muc7 mRNA had significantly higher sensitivity than urine cytology in detection of bladder cancer.Conclusion The sensitivity of Muc7 mRNA test is superior to urine cytology in detection of bladder cancer.
