Purpose : ICAM-1(Intercellular Adhesion Molecule-1) is a cell adhesion molecule
which facilitates the binding of LAK(Lymphokine Activated Killer)cell and cytotoxic T
cell to tumor cell. This study investigates the role of ICAM-1 in transitional cell
carcinoma(TCC) of bladder.
Materials and Methods : Immunohistochemical stain for ICAM-1 was done in 42
paraffin embedded tissue of primary TCC of bladder. And we compared the expression
of ICAM-1 and the degree of immune cell infiltration, tumor grade, stage and suvival
rate of the patients.
Results : Immunohistochemical examination demonstrated expression of ICAM-1 on 17
of 42 bladder TCC but not on five normal transitional cells. The more frequently
immune cells infiltrated, the more frequently ICAM-1 was expresses (p=0.018). And
ICAM-1 was frequently expressed in higher histopathological grade and higher stage
tumors(p=0.035, p=0.002). Survival rate was lower in ICAM-1 expressed tumors than in
ICAM-1 non-expressed tumors even though it is insignificant statistically(p=0.11).
Conclusions : These results suggest that ICAM-1 plays an important role on immune
therapy for bladder TCC, and ICAM-1 expression in bladder TCC could be another
prognostic factor and used as a response predictor for immune therapy such as
intravesical BCG instillation.
