However, the clinicopathologic information such as age, gender, tumor location, gross pathology type, differentiation grade, T stage, preoperative carcinoembryonic antigen (CEA) level, preoperative carbohydrate antigen 19-9(CA19-9) level, and microsatellite instability (MSI) status had no significant correlation with the GADD45B expression. The gene discussed is GADD45B; the disease is neoplasm.
