P504S positive CKH showing basal cell deletion is a tumor cell test result, suggesting that prostate cancer may be present. P504S positive CKH showing basal cell deletion may be a sign of prostate cancer, but also according to the P63 test results, if the P63 test results are positive, the chances of prostate cancer are higher; but also according to the diagnostic results of the Ki67 analysis, Ki67 tumor proliferation index of 8%, indicating that the tumor cell proliferation is more active. If at present it is only simple P504S positive CKH showing the absence of basal cells, it can not be surely judged as prostate cancer, because it is found in the diagnostic data of prostate cancer that some prostate cancer patients may be negative for P504S. In order to accurately identify whether it is prostate cancer or not, it is recommended to go to the hospital as soon as possible to do tumor marker screening, and combined with pathological examination for analysis.
