Sigmoid colon cancer patients with postoperative examination of cancer index (CEA) decreased is the possibility of improvement. Patients should pay more attention to rest, do not stay up late, pay attention to the diet of light, fluid-based food.
Sigmoid colon cancer is a malignant tumor of the digestive tract that occurs in the sigmoid colon. Carcinoembryonic antigen (CEA) is an acidic glycoprotein with the characteristics of human embryonic antigen, which exists on the surface of cancer cells differentiated from endodermal cells, and is a structural protein of cell membranes.CEA is a non-specific marker for the early diagnosis of colorectal cancer, and it has an important clinical value in the evaluation of the efficacy of sigmoid colon cancer.
After surgery for sigmoid colon cancer, patients need to check the cancer index (CEA) regularly and should be given adjuvant chemotherapy if there are poor prognostic factors.
