[Abstract]:PurposeTo investigate the expression and association of hypoxia-inducible factor-1 alpha-hypoxia-inducible factor-1 (HIF-lalaa), hepatocyte growth factor receptor (c-metr) and microvesel density (MVD) in human laryngeal squamous cell carcinoma (LSCC), and to explore the role of HIF-1 偽 and c-met in laryngeal squamous cell carcinoma (LSCC) development and lymphatic metastasis.It provides a theoretical and experimental basis for the pathogenesis and gene therapy of laryngeal carcinoma.MethodFifty-eight cases of laryngeal squamous cell carcinoma (SCC) from 2006 to 2010 in the first affiliated Hospital of Zhengzhou University were collected. Streptavidin peroxidase (SP) immunohistochemical technique was used.The expression of HIF-1 偽 and c-met in different differentiation types of laryngeal squamous cell carcinoma (LSCC) was detected, and the microvessel density (MVD) was measured. The relationship between HIF-1 偽 c-met and MVD was observed.ResultThe expression of HIF-1 偽 was brown granules, mainly located in the nucleus and partly in the cytoplasm.The mean integral optical density of the average integrated optical was 121.91 鹵3.59133.31 鹵2.65146.76 鹵6.61 in high, middle and low differentiated laryngeal carcinoma, respectively. The results of ANOVA showed that there were significant differences in HIF-1 偽 among different differentiation types.The AIOD of positive region in cervical lymph node metastasis group and non-metastasis group was 142.85 鹵7.48126.73 鹵5.82, respectively. The results of t test showed that the difference between the two groups was statistically significant (P 0.05). The positive rate of c-met was brown granules, mainly located in cytoplasm and cell membrane.The AIOD in high, middle and low differentiated laryngeal carcinoma was 120.23 鹵3.04131.04 鹵4.60159.12 鹵9.26, respectively. The results of variance analysis showed that the difference of c-met between different differentiation types was statistically significant (P 0.05).The AIOD of positive region in cervical lymph node metastasis group and non-metastasis group were 149.88 鹵14.85124.81 鹵5.87, respectively. T test results showed that the difference between the two groups was statistically significant (P 0.05);The MVD in poorly differentiated laryngeal carcinoma was 11.82 鹵2.38 鹵23.08 鹵4.95 鹵39.44 鹵4.30, respectively. The results of variance analysis showed that there was significant difference in MVD between different differentiation types.There was a significant positive correlation between HIF-1 偽 and c-met and the correlation coefficient between HIF-1 偽 and MVD, which was statistically significant. The correlation coefficient between HIF-1 偽 and MVD was also positively correlated with MVD (r = 0.921, P 0.001), which indicated that there was a positive correlation between HIF-1 偽 and MVD, which indicated that there was a positive correlation between HIF-1 偽 and MVD, which indicated that there was also a positive correlation between HIF-1 偽 and MVD.ConclusionHIF-1 偽 c-met and neovascularization play an important role in the development and development of laryngeal squamous cell carcinoma. HIF-1 偽 c-met may be a potential target for the treatment of laryngeal squamous cell carcinoma.
