Discuss the complications of prostate cancer

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 humans. In order to reduce the incidence of prostate cancer, we humans should understand the complications of prostate cancer:

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.

The above are the complications of prostate cancer. Expert Tips: If you have symptoms of disease, do not delay diagnosis and go to a regular hospital for treatment in time to avoid delaying the disease and causing serious consequences.
