ABSTRACT

Forecasting the colorectal cancer prognosis mainly based on the accurate pathological stages,the primary carcinoma infiltrated depth,the cell differentiation degree and the capillaries infiltrated in histology result,and the outcome can be obtained latter 3-7 days after the opemtion.But in traditional lymph node inspection method,identifying the quantity and the anatomy locality of metastasized lymph node normally costs long time,sometimes cannot obtain the result.M addition,to identify the stage of the cancer is a key point to determine the assistant chemotherapy is useful or not,for both doctor and patient,because the excessive treatment and the insufficient treatment are both harmful to the patient.Now overseas has an abvoad study showes that regional lymph node metastasis have something to do with the concentration of(Carcinembryonic,CEA)in the lymph node.The CEA concentration can be obtained simply and directly.So,testing the CEA concentration in lymph node may become a new method in the diagnosis of lymph node metastasis for patients with colorectal cancer.
