Symptoms of metastatic lymph nodes in renal cell carcinoma

summary

Renal cell carcinoma originated from renal tubular epithelium, and its growth rate was generally slow, but sometimes very fast. Most of them were wrapped by a layer of fibrous capsule and could grow in any part of renal parenchyma. Most of the surface vessels were dilated. They were found in different sizes. Most of them are single, a few have multiple. The tumor may invade the renal parenchyma, or infiltrate the renal capsule and penetrate into the perirenal fat. This amount of metastasis, together with the original amount of a certain organ, can be recombined into a new cluster, which may form a new tumor. Let's have a look.

Symptoms of metastatic lymph nodes in renal cell carcinoma

Renal cell carcinoma is an important way of metastasis. Tumor cells invade veins, causing extensive blood metastasis. The most common metastatic organ is lung, which is second only to lymph node metastasis. The symptoms of renal metastatic lung cancer are lighter than those of primary lung cancer, but it also has the clinical manifestations of lung cancer such as cough, chest tightness and chest pain; Bone metastasis is also a common organ of renal cell carcinoma with blood metastasis.

According to statistics, 15% ~ 30% of renal cell carcinoma can be metastasized by lymphatic pathway. The left side metastasized to the renal pedicle, anterior aorta and left lateral lymph nodes; The right side metastasized to the renal hilum, anterior inferior vena cava lymph nodes, aorta and inferior vena cava lymph nodes. The hilar lymph nodes are very early and often involved. Lymph node metastasis is very important to determine the stage, treatment and prognosis of renal cell carcinoma.

Renal cell carcinoma grows up gradually. To a certain extent, it will penetrate through the tumor capsule and spread around. It will invade the calyces and pelvis inward, break through the renal capsule outward, invade the perirenal fat and fascia, and spread to adjacent tissues and organs, such as colon, adrenal gland, liver, spleen and diaphragm. Adrenal metastasis belongs to late stage in clinical stage, but it can still be regarded as local invasion and has a good prognosis.

matters needing attention

The primary tumor has a lot of hematuria, pain, hypertension, liver dysfunction and other serious symptoms, which can not be relieved by medical treatment, the number of metastases is very small, it is estimated that all the patients can be removed by surgery. We must be careful not to spread too much.
