There are more lesions leading to metastasis of enlarged lymph nodes adjacent to the inferior vena cava, such as liver cancer, gastric cancer, retroperitoneal tumor, pelvic tumor and so on.
Malignant tumors have invasive characteristics, and with the continuous development of lesions, cancer cells may metastasize to local and distant organs and tissues through blood and lymphatic pathways. Inferior vena cava is an important venous channel in human body, and there are lymphatic vessels next to the vein, connecting adjacent lymph nodes.
If the patient has liver cancer, stomach cancer, retroperitoneal tumor, pelvic tumor and other lesions, the cancer cells may metastasize to the lymph nodes in the region through lymphatic route.
Therefore, after the diagnosis of metastasis of enlarged lymph nodes is confirmed, relevant examinations, such as ultrasound, CT, MRI, arteriography, gastrointestinal microscopy, etc., should be completed to clarify the specific lesions of the patient. Then, taking into account the stage of the disease and the patient’s physical quality, the patient should be actively treated with surgery, radiotherapy, targeted drugs and other measures to try to stabilize the condition and prolong the patient’s survival time.
