What are the classifications of prostate cancer?

Although the probability of prostate cancer in our country is not very large, it occurs more in Europe and the United States, but there is still a possibility of occurrence, so we still have to learn more about prostate cancer, and we will introduce you to the classification of prostate cancer, let's learn about it together.

Latent cancer of the prostate

Refers to adenocarcinoma of the prostate that originates in the prostate gland and is found by pathological examination at postmortem without signs and symptoms of prostate disease during life. Latent carcinoma can occur anywhere in the prostate, but is more common in the central and peripheral regions and is often well-differentiated adenocarcinoma. The incidence rate is reported abroad as 18%~50%, and the domestic report is about 34%. Statistical studies have shown that the incidence of latent prostate cancer may be related to environmental and genetic factors.

Incidental cancer of the prostate

Clinically, benign prostatic hyperplasia is the main symptom, and prostate cancer is found on histological examination in the resection of hyperplastic prostate tissue. Its histological manifestations are well-differentiated adenocarcinomas, mainly tubular adenocarcinoma and ethmoid reticular adenocarcinoma, and a few are poorly differentiated adenocarcinomas, and the incidence of incidental prostate carcinoma in foreign countries is 10%~30%. The domestic incidence rate has been reported to be about 5%.

Occult cancer of the prostate

The patient has no signs or symptoms of prostate disease, but pathology on lymph node biopsy or bone puncture proves prostate cancer. It can be further confirmed by prostate biopsy. These patients have elevated serum levels of prostate-specific antigen (pSA) and prostate acid phosphatase. Biopsies were positive for pSA and/or pAp immunohistochemical staining.

Clinical cancer of the prostate

Prostate cancer is diagnosed by clinical examination (digital, ultrasound, CT, or magnetic resonance, etc.) and can be confirmed by biopsy. Elevated serum pSA and pAp can also be used to aid in diagnosis. In most patients, prostatic nodules can be palpated on digital anal examination, and ultrasonography shows that prostatic nodules are irregular in shape, uneven in echo, and low in echo.

It can be seen that there are still many classifications of prostate cancer, so when prostate cancer occurs, we should use different methods to treat prostate cancer according to different types, so that the treatment effect is also the most obvious. In addition, we need to detect prostate cancer early, so that it is easier to treat.
