The moderate differentiation of middle-differentiated adenocarcinoma of the ascending colon only shows its high degree of malignancy, and the severity cannot be generalized, and the prognosis is related to its specific clinical stage. 1. Early clinical stage. At this time, the cancer cells have not yet spread and are relatively limited, so radical resection can be chosen for treatment, with the possibility of complete cure, and its cure rate can reach 80%. 2. Middle clinical stage. Patients with mid-stage ascending colon cancer can be cured if they only have lymph node metastasis. Surgical radical resection and lymph node dissection are feasible. 2. Advanced clinical stage. In patients with advanced stage of ascending colon cancer, the cancer develops rapidly, and metastasis to surrounding tissues, organs or distant organs has appeared, which is so serious that it is difficult to carry out surgical treatment and cannot be cured completely, and the survival period will be reduced. The presence of moderately differentiated cancer of ascending colon should be treated actively according to the doctor’s prescription.
