Survival curves of the expression of MUC family genes by different tumor location. Kaplan Meier curves analyze the relationships between survival and location of tumors for MUC1 (A), MUC2 (B), MUC5AC (C), and MUC6 (D), for tumors located in (1) the lower end of the common bile duct, (2) the papillary duodenum, and (3) the ampullary duodenum. The solid lines indicate tumors that were negative for the MUC gene expression, the dashed lines indicate tumors that were positive for the MUC gene expression, the open circles (○) indicate censored patients with tumors negative for the gene expression, and the open square (□) indicate censored patients with tumors positive for the gene expression.
