What happens if colon cancer metastasizes to the abdominal wall after surgery?

Generally speaking, peritoneal metastasis after colon cancer surgery is relatively rare. If a patient is found to have ascites during an abdominal CT scan, it may be caused by tumor cells invading the serosal layer.

1. Cause: Generally speaking, in clinical practice, the common ways of spreading malignant tumors are lymphatic and hematogenous. The most common distant metastasis sites of colorectal cancer are the liver and lungs, followed by the pelvis. However, some patients may also experience intra-abdominal implantation metastasis, which occurs in the abdominal organs such as the lesser omentum sac or greater omentum, and new masses grow;

2. Treatment: If the patient's condition is mild, chemotherapy can be used to control it. Commonly used drugs include oxaliplatin injection, capecitabine tablets, etc. At the same time, radiotherapy can be used to kill the lesions in the body, thereby achieving the purpose of relieving symptoms. In addition, targeted drugs such as bevacizumab injection and cetuximab injection can also be used for adjuvant treatment according to the doctor's advice;

3. Precautions: Patients are advised to eat a light and easily digestible diet and avoid spicy and irritating foods to avoid aggravating the symptoms. In addition, patients should take more rest, get enough sleep, and try not to stay up late. At the same time, they should maintain a good attitude and actively cooperate with doctors for relevant treatment measures.
