OBJECTIVE: To investigate the inhibition effect ofβ-elemene on the growth and metastasis of laryngeal carcinoma and the underlying mechanism.
METHODS: Sixty-six rabbits were vaccinated with suspension of VX2 cancer tissues to establish a rabbit laryngeal carcinoma model and then they were randomly treated with the injection of 0.9% sodium chloride solution (as a control), cisplatin, orβ-elemene from the seventh day after vaccination. The rabbits were sacrificed three weeks after vaccination. The laryngeal tumor was dissected. and the volume of tumor and the inhibitory rate of tumor growth were measured. The expressions of PCNA (proliferation cell nuclear antigen), Bcl-2 (B-celllymphoma-2) and VEGF-D (vascular endothelial growth factor D) in tumor were semiquantitatively examined by immunohistochemistry.
RESULTS: The inhibition rates of tumor growth inβ-elemene-treated group and the cisplatin-treated group were 48.5% and 51.4%, respectively. The expressions of Bcl-2 in β-elemene-treated group and cisplatin-treated group were significantly lower than the control (P<0.05), but with no significant difference betweenβ-elemene-treated group and cisplatin-treated group. The expression of PCNA in β-elemene-treated group was significantly decreased compared to control group (P<0.05). The expression of VEGF-D inβ-elemene-treated group was lower than that in control group or the cisplatin-treated group (P<0.05).
CONCLUSION: β-elemene can inhibit the growth of rabbit VX2 laryngeal tumor, which may be associated with the inhibition of factors related to tumor growth and metastasis.
