Pathological classification of prostate cancer

Pathological classification of prostate cancer

Prostate cancer mainly occurs in men over 50 years old, occasionally in young people and even children. More than 95% are adenocarcinomas, and the rest are transitional cell carcinomas, squamous cell carcinomas and sarcomas. Prostate cancer occurs from the alveoli and ducts, often originating from the peripheral zone and rarely in the central area. Prostate cancer often has multiple lesions, and a single nodule accounts for less than 10%.

Transitional cell carcinoma and squamous cell carcinoma account for less than 3% of the cases. They often occur from the transitional epithelium covering the end of the prostate duct and may occur together with adenocarcinoma. The average age of onset is 10 years younger than that of adenocarcinoma, and the acid phosphatase is normal. They do not respond to radiation and endocrine therapy, grow rapidly, and have a poor prognosis. Sarcoma is common in young people, grows rapidly, does not respond to radiation and endocrine therapy, and has a very poor prognosis.

Prostate cancer can be divided into three pathological types:

1. Latent type: The tumor is small and asymptomatic, and does not metastasize. Commonly seen in autopsies.

2. Clinical type: The tumor already has local symptoms, with obvious invasion and late metastasis.

3. Hidden type: The primary lesion is small and difficult to detect, but it often metastasizes early.

Symptoms of prostate cancer:

1. If you have prostate cancer, you may have a slow urine flow that gradually worsens, and you may also feel like you can’t urinate completely. You may also experience symptoms such as frequent urination, urgency, interrupted urine flow, and difficulty urinating.

2. What are the early symptoms of prostate cancer? Early patients may experience oliguria, anuria, and urinary incontinence. If you find yourself having oliguria or anuria, don't be careless. You should go to the hospital for examination as soon as possible to avoid delaying for too long and worsening the condition.

3. In the early stages of prostate disease, patients will experience bone pain, typically in the lumbar and pelvic regions. The pain will be persistent and will be more intense when the patient is resting in bed.

What are the early symptoms of prostate cancer? In addition to the three points mentioned above, it also manifests as enlarged inguinal lymph nodes, which usually occurs in the late stage of cancer. Sometimes the lower limbs may swell due to tumor compression, which seriously affects the patient's health. Its systemic symptoms can show weight loss, fatigue, low fever, progressive anemia, and cachexia.
