Expression of Vasohibin-1 and LGR5 in oral squamous cell carcinoma and their clinical significances / 临床与实验病理学杂志

ABSTRACT

Purpose To detect the expression of vasohibin-1 (VASH-1) and LGR5 protein in oral squamous cell carcinoma(OSCC) and their clinical significances. Methods Expression of VASH-1 and LGR5 protein in 223 cases of OSCC tissues and 80 cases of adjacent normal oral mucosa tissues was examined by the immunohistochemicalEliVision method. Results The positive rate of VASH-1 and LGR5 protein in OSCC tissues and the control tissues was 59.6％, 55.6％ and 12.5％, 13.8％, respectively. There was a significant difference between the two groups (P＜ 0.05 ). The expression of VASH-1 and LGR5 protein was significantly related with grades of tumors, size of tumors, lymph node metastasis, and TNM stages (all P＜0.05). The positive expression of VASH-1 and LGR5 was not relevant to age, gender, location of tumor, smoking, and alcohol (all P＞ 0.05). Spearman correlation analysis showed that there was a positive association between the VASH-1 expression and LGR5 expression (rs =0.718, P＜0.001). Conclusion The expression of VASH-1 and LGR5 in OSCC is high and may promote the initiation and development of the cancer, which play an important role in the invasion, metastasis, and prognosis of OSCC.
