Background:
Odontogenic keratocyst (OKC) is a developmental odontogenic cyst with an aggressive clinical behavior suggesting a change in its terminology from a cyst to a tumor and has now been renamed as keratocystic odontogenic tumor (KCOT). The purpose of this study was to assess and compare angiogenesis in ameloblastoma and OKC.
Materials And Methods:
Angiogenesis was assessed by studying the immunohistochemical expression of vascular endothelial growth factor (VEGF). The study samples included 15 ameloblastomas and 15 KCOTs. The immunoreactivity was statistically evaluated using Mann-Whitney U-test.
Results:
VEGF expression was higher in ameloblastoma than KCOTs. However, a non-significant difference of VEGF expression was noted between ameloblastoma and KCOTs (P = 0.345).
Conclusion:
The results suggest that tumor angiogenesis may play a significant role in aggressive biologic behavior of KCOT. Thus, angiogenesis could be a potent target for developing anatiangiogenic therapeutic strategies.
