Colon adenocarcinoma is a common type of colon cancer, with intermediate differentiation suggesting that malignancy is not very high, and surgery is the only possible way to achieve radical cure.
Other than that, chemotherapy, radiotherapy, targeted therapy, immunotherapy, and interventional therapy are also available. The relative treatment options need to be tailored to the specific condition.
The etiology of the disease can be determined by ultrasound colonoscopy and biopsy for pathological staging. If the lesion is intramucosal or submucosal and does not invade the muscular layer, surgery is performed as soon as possible, and chemotherapy and radiotherapy are not required after surgery.
If the lesion invades the muscular layer, surgical excision of the lesion and lymph node dissection around the cancer are required. 6-8 courses of chemotherapy are given after surgical excision of the lesion, and local radiotherapy treatment is done for colon cancer close to the pelvis. Using these combined measures, the chances of recurrence of colon cancer can be reduced.
When extensive infiltration and metastasis have occurred and surgery is not possible, chemotherapy can be considered, and targeted therapy has a delaying effect. When there are complications, then palliative surgery can be done to improve the quality of life.
