Abstract | BACKGROUND/AIM: Treatment options of advanced cholangiocarcinoma (CC) are unsatisfactory and new therapeutic approaches are mandatory. Dysregulations of the mitogen-activated kinase (MAPK) pathway associated with proliferative advantages of tumors are commonly observed in CCs. The novel multi- kinase inhibitor sorafenib potently suppresses the growth of various cancers by inhibiting kinases of wild-type B-Raf, mutant(V559E)B-Raf and C-Raf but its effects on CC remains to be explored. We therefore studied the antineoplastic potency of sorafenib in human CC cells alone and in combination with conventional cytostatics or IGF-1R inhibition. METHODS AND RESULTS: CONCLUSION: Our study demonstrates that the growth of human CC cells can be potently suppressed by sorafenib alone or in certain combination therapies and may provide a promising rationale for future in vivo evaluations and clinical trials.
