How is prostate cancer classified

In recent years, prostate cancer has become one of the major diseases that endangers society and human health, and it has brought great pain and distress to mankind. How is prostate cancer classified?

(1) Latent prostate cancer: refers to adenocarcinoma originating from the prostate that is discovered by pathological examination during postmortem examination in the absence of symptoms and signs of prostate disease during life. Latent cancer can occur in any part of the prostate, but is more common in the central and peripheral areas, and is often a well-differentiated adenocarcinoma. Its incidence rate is reported to be 15% to 50% abroad. A study by the Urology Research Institute of Peking University Medical School in my country reported that the incidence rate of latent prostate cancer is 34%. Statistical studies have shown that the incidence of latent prostate cancer may be related to environmental and genetic factors.

(2) Incidental prostate cancer: The main clinical symptom is benign prostatic hyperplasia. Prostate cancer is found in the resected hyperplastic prostate tissue through histological examination. Its histological manifestation is well-differentiated adenocarcinoma, mainly tubular adenocarcinoma and cribriform adenocarcinoma, and a few are poorly differentiated adenocarcinoma. The incidence of incidental prostate cancer abroad is 10% to 30%. The incidence in China is reported to be around 5%.

(3) Occult prostate cancer: The patient has no symptoms or signs of prostate disease, but pathological examination of lymph node biopsy or bone puncture specimens confirms prostate cancer. This can be further confirmed by prostate puncture biopsy. This type of patient has elevated serum prostate-specific antigen (PSA) and prostatic acid phosphatase levels. PSA and/or PAP immunohistochemical staining of biopsy tissue are both positive.

(4) Clinical prostate cancer: Prostate cancer is diagnosed by clinical examination (digital examination, ultrasound, CT or MRI, etc.), and can be confirmed by biopsy. The increase of serum PSA and PAP can also assist in diagnosis. Most patients can feel prostate nodules by rectal examination, and ultrasound examination shows that the prostate nodules are irregular in shape, uneven in echo and low in echo.
