Although the probability of prostate cancer occurring in our country is not very high, it occurs more frequently in European and American countries, but it is still possible, so we still need to learn more about prostate cancer. Below we will introduce to you the classification of prostate cancer, and we will learn about it together. Latent prostate cancer It refers to adenocarcinoma originating from the prostate that is found 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 18% to 50% abroad, and about 34% in China. Statistical studies have shown that the incidence of latent prostate cancer may be related to environmental and genetic factors. Incidental prostate cancer The main clinical symptom is benign prostatic hyperplasia. In the resected hyperplastic prostate tissue, prostate cancer is found by 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 domestic incidence rate is reported to be around 5%. 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. The serum prostate specific antigen (pSA) and prostatic acid phosphatase levels of this type of patient are elevated. Immunohistochemical staining of pSA and (or) pAp in biopsy tissue is positive. 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. It can be seen that there are 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 the most obvious. In addition, we must detect prostate cancer early, so that it is easier to treat. |
