What are the common types of prostate cancer? Introduction to the four types of prostate cancer

Prostate cancer is currently one of the most common malignant tumors, and its incidence is increasing year by year. Prostate cancer is also divided into different types. Although the symptoms of different types are similar, there are certain differences in the treatment methods. The following are the four common types of prostate cancer:

One of the four major types of prostate cancer: 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.

These patients have elevated serum prostate-specific antigen (pSA) and prostatic acid phosphatase levels. Immunohistochemical staining of pSA and/or pAp in biopsy tissue is positive.

The second of the four major types of prostate cancer: latent prostate cancer

It 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.

The incidence rate is reported to be 15% to 50% abroad. A study by the Urology Research Institute of Peking University Medical School in China 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.

The third of the four major types of prostate cancer: 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.

Four major types of prostate cancer: 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%.

Diseases of the prostate itself are also a key factor in causing prostate cancer. Therefore, although prostate diseases are often very difficult to cure, they should also be treated with emphasis, especially to avoid repeated recurrences, which repeatedly stimulate the prostate. This is also a key point in preventing prostate cancer.
