A vascular thrombus means that the cancer cells have appeared in a blood vessel or lymphatic vessel, which carries a higher risk of spreading and requires more aggressive treatment. The presence of a cancerous embolus in the vasculature is a high-risk factor for recurrence, indicating that the cancer cells have entered the vascular system, such as lymph nodes and blood vessels. Since blood vessels and lymphatic vessels belong to the systemic circulatory system, the cancer embolus can pass through the vascular system for distant metastasis, such as to the lungs and bones through blood vessels, and to nearby or distal lymph nodes through lymphatic vessels. A more aggressive postoperative regimen needs to be given after surgery when a cancerous embolus is detected. Combined chemotherapy regimens should be used as much as possible, so as to better kill the cancer cells that may remain in the body, reduce the chances of recurrence and metastasis after surgery, prolong the time of recurrence, and improve the overall survival time of the patient. It is also necessary to strengthen the frequency of rechecking in order to detect recurrence in time. It is recommended to choose the most suitable treatment plan for oneself under the guidance of doctor and actively cooperate with the treatment to improve the quality of life and prolong the survival time.
