摘要:: To clarify the role of neural cell adhesion molecule (NCAM) in perineural invasion, NCAM expression was studied by immunohistochemical staining in 26 cases with gallbladder cancer. In gallbladder cancer, the incidence of perineural invasion and that of positive NCAM expression was 42% and 31%, respectively, which are less frequent than those of bile duct cancer in our previous report. Perineural invasion was observed in 88% of the patients with positive expression of NCAM and in 22% of those with negative expression. The former is similar to that of bile duct cancer but the latter is significantly lower. Eighty percent of the cancer cells that invaded the perineural space were positive for NCAM, when the primary tumor was positive for NCAM expression. Therefore, in gallbladder cancer, positive cells in NCAM expression likely invade the perineural spaces. However, the perineural invasion of negative cells in NCAM expression is not likely to occur as compared to bile duct cancer. In conclusion, perineural invasion in gallbladder cancer is not as common as in bile duct cancer, but the role of NCAM in perineural invasion is more important in gallbladder cancer than in bile duct cancer.
