What are the complications of prostate cancer?

Prostate cancer is a very common and extremely harmful malignant tumor. The disease has a great impact on the patient's work and life. In modern society, men are under great pressure in work and life, and the living environment is getting worse and worse, which has led to a continuous surge in the incidence of prostate cancer. At the same time, prostate cancer is often accompanied by other complications when it occurs.

The first lymph nodes invaded by prostate cancer with lymphatic metastasis are the obturator-internal iliac chain. In fact, the lymph nodes at the obturator foramen are generally not invaded. In clinical practice, the internal iliac lymph nodes are often called obturator lymph nodes. They are located on the inner side of the external iliac vein and are the most important lymph nodes that should be removed along the course of the internal iliac vessels.

In recent years, the diagnosis of lymph node metastasis relies on CT and MR, but they cannot detect small lesions. Lymph node angiography can detect 70% to 90% of metastases. However, the false negative and false positive rates are high, and it is rarely used in recent years. The most valuable diagnostic modified lymph node dissection, that is, the removal of the lymph nodes between the internal and external iliac vessels and the obturator foramen, is more accurate for staging and can avoid complications such as lymph leakage, lymphadenopathy, and lower limb swelling caused by the previous removal of iliac vessels, obturator foramen, pelvic wall, and anterior iliac lymph nodes, because even extensive dissection cannot prevent existing spread.

When ureteral obstruction is detected during intravenous urography of distant metastasis, it indicates that the tumor has invaded the seminal vesicle, bladder neck, and lymph nodes, and may have distant metastasis.

Bone metastasis is common, second only to lymph nodes. Whole body isotope scanning is enhanced but the plain film is normal, which should be considered as metastasis. Lung X-ray can detect lung metastasis, which is often lymphatic spread and nodules are rare.

From the above introduction, we can see that there are still many complications of prostate cancer, and its harm is quite large. I believe you should have a general understanding of prostate cancer now. Experts suggest that everyone must do a good job of prevention in daily life. Once you find that you are unwell, you must seek treatment in time to avoid missing the best treatment time.
