Abstract:
Objective To study the serum levels of PSA, PAP joint detection in diagnosis of prostate cancer and the effect of estrogen on it.Methods60 patients with prostate cancer were selected in Jinyun County People's Hospital department of urology patients, giving diethylstilbestrol 3mg, oral once a day, and give Aspirin Enteric-coated Sustained Release Tablets 100mg oral, once daily, for 2 consecutive months.At the same time, we selected 60 cases of patients with benign prostatic hyperplasia, normal control group of 60 healthy subjects were the same period.Using radioimmunoassay, were observed inprostatic hyperplasia group, normal control group, the prostate cancer group before treatment, the prostate cancer group after treatment, serum PSA, PAP levels, as well as the group before and after treatment in patients with prostate cancer IPSS score index.ResultsThe prostate cancer group, serum PSA, PAP levels were significantly higher than that of benign prostatic hyperplasia group and normal control group, the difference was statistically significant (P<0.05);no significant difference was found between the prostatic hyperplasia group and normal control group, PSA in prostate cancer positive detection rate and the detection sensitivity is 78.33% the specificity was 70%, the index of PAP in prostate cancer, and the positive detection rate and the detection sensitivity was 53.33%, specificity index reached 93.33%;PSA for prostate cancer detection positive rate and sensitivity was higher than that of PAP, but the specificity is less than PAP, the difference is statistically significant (P<0.05) after treatment;the prostate cancer group, serum PSA, PAP levels were improved, compared with that before treatment, serum PSA, PAP levels decreased significantly, the difference was statistically significant (P<0.05);and after the treatment, the prostate cancer group of prostate symptoms have improved, compared with before treatment, IPSS score decreased significantly, the difference was statistically significant (P<0.05).ConclusionThe combined detection of serum PSA, PAP in the diagnosis of prostate cancer can improve the sensitivity and specificity, and can be used for early diagnosis of prostate cancer;estrogen can lower their level, improve the symptoms of prostate cancer, inhibit the progress of the disease.
