Experts explain the common pathways of renal cancer metastasis

Kidney cancer is a common malignant tumor in clinical practice, which seriously harms the health of patients. In the late stage of kidney cancer, kidney cancer metastasis will occur, which is more harmful to patients. What are the common ways of kidney cancer metastasis? The following experts will tell you about the common ways of kidney cancer metastasis.

In general, the common ways of renal cancer metastasis are:

Direct infiltration: This is the most common way for renal cancer to metastasize. Renal cancer gradually grows, breaks through the tumor capsule and spreads to the surrounding areas, invading the renal pelvis inward, breaking through the renal capsule outward to invade the perirenal fat and fascia, and spreading to adjacent tissues such as the colon, adrenal glands, liver, spleen, and diaphragm.

Lymphatic pathway: According to statistics, 15% to 30% of renal cancer can metastasize via the lymphatic pathway. On the left side, it metastasizes to the renal pedicle, the preaortic and left lateral lymph nodes; on the right side, it involves the renal hilum, the pre-inferior vena cava lymph nodes, and the lymph nodes between the aorta and the inferior vena cava.

Blood metastasis: It is also an important pathway for renal cancer metastasis. Cancer cells invade veins from capillaries and intrarenal veins to renal veins, forming tumor thrombi in the veins. These thrombi can further extend into the inferior vena cava to reach the right atrium, and then to the lungs, iliac bones, and other organs, causing extensive blood metastasis.

The above is an introduction to the common ways of renal cancer metastasis. I hope it will be helpful to you. For more questions about renal cancer metastasis, you can consult our online experts, who will answer them in detail.
