摘  要:目的探讨血管生成拟态和内皮依赖性血管在喉鳞状细胞癌侵袭转移过程中的作用,用以评估患者的预后。方法回顾性分析203例喉癌患者临床病理资料及随访结果。CD3l和过碘酸雪夫试剂免疫组化双重染色及CD31染色标记石蜡包埋喉癌组织中血管生成拟态及内皮依赖性血管的表达,应用Kruskal-Wallis检验和单因素方差分析比较血管生成拟态和内皮依赖性血管与喉癌患者临床病理参数的关系,并应用Kaplan—Meier进行生存分析,评估患者的预后。结果血管生成拟态与喉癌患者的淋巴转移、肿瘤分期和组织病理学分级有关(P值均〈0.05)。而内皮依赖性血管与喉癌患者的发病部位、肿瘤分期、T分期和远处转移有关(P〈0.05)。单因素分析表明,血管生成拟态(P=0.014)、肿瘤分期(P=0.009)、T分期(P=0.013)、淋巴转移(P=0.013)、组织病理学分级(P=0.038)、肿瘤大小(P=0.028)和放疗(P〈0.0001)与喉癌患者总生存率有关。而血管生成拟态(P=0.011)、发病部位(P=0.049)、肿瘤大小(P=0.001)和放疗(P〈0.0001)与喉癌患者无瘤生存率有关。多因素分析结果表明,血管生成拟态是影响喉癌患者预后的独立危险因素。结论喉癌组织中内皮依赖性血管与血管生成拟态共存。血管生成拟态可能通过促进区域淋巴转移影响喉癌患者的生存,对预测喉癌患者的转移和生存具有重要价值。Objective To investigate the contribution of vasculogenic mimicry (VM) and endothelium-dependent vessel (EDV) to invasion and metastasis of laryngeal squamous cell carcinoma (LSCC). Methods A total of 203 cases with LSCC was reviewed and followed up. VM and EDV in LSCC tissues were assessed by double staining with anti-CD31 immunohistochemistry and periodic acid-schiff. Kruskal-Wallis test and one-way ANOVA were used to analyze the relationship between VM, EDV and clinicalpathology parameters of LSCC. Kaplan-Meier analysis was used to evaluate overall survival (OS) of patients with LSCC. Results VM related to pTNM stage, lymph node metastasis and pathology grade of LSCC, while EDV related to primary sites, pTNM stage, T stage and distant metastasis of LSCC. Univariate analysis showed VM ( P = 0. 014 ), pTNM stage ( P = 0. 009 ), T stage ( P = 0. 013), nodal status ( P = 0. 013 ), histopathology grade ( P = 0.038 ), tumor size ( P -= 0.028 ), and radiotherapy ( P 〈 0.0001 ) related to OS. VM ( P = 0.011 ), primary sites ( P - 0. 049 ), tumor size ( P = 0. 001 ) and radiotherapy ( P 〈 0. 0001 ) related to disease free survival. Multivariate analysis indicated that VM was an adverse predictor for both OS and disease free survival. Conclusions Both VM and EDV existed in LSCC. VM contributed to progression of LSCC through promoting lymph node metastasis. VM is an independent predictor for the prognosis of LSCC.
