摘 要:目的探讨喉癌组织中血管内皮生长因子(VEGF)表达与CD83阳性树突状细胞(DC)分布的关系。方法42例喉癌组织经抗VEGF、抗CD83抗体免疫组化染色,观察喉组织中CD83阳性DC及VEGF分布,以及CD83阳性DC密度与VEGF表达强度的相关性。结果42例肿瘤标本中“-”12例,“+”者14例,“++”者16例。CD83+树突状细胞形态不规则,表面有许多不规则树状突起,主要分布于癌周组织内,趋向于成群分布;偶可见到CD83+DC位于靠近癌周组织的癌巢间间质内。喉癌组织中VEGF的表达明显升高的病例,其CD83+DC密度显著降低。结论VEGF的表达与喉癌组织中CD83+DC含量呈明显的负相关。Objective To investigate the relationship between the expression of vascular endothelial growth factor(VEGF) and CD83^+ dendritic cell density in human laryngeal carcinoma. Methods 42 laryngeal carcinoma tissues were investi- gated by immunohistochemical studies with anti - VEGF, anti - CD83 antibodies. Results For intensity of VEGF staining, 12 tumors were graded as negative staining, 14 as " + ", 16 as " + + "; CD83 ^+ mature DCs were irregular in shape and extended many irregular dendritic protrusions; CD83^+ mature DCs were confined to peritumoral areas in groups. Sometimes, CD83^+ DCs were found in stroma among cancer nests nextto peritumoral areas. A close correlation between VEGF and CD83 ^+ DC density was found in laryngeal carcinoma. An intensive VEGF expression is associated with the lower density DC. Conclusion The result suggests that the density of CD83^+ DCs in laryngeal carcinoma is negatively related to the expression of VEGF.
