Methods: The prognostic value of pathological and molecular margin was studied in 253 cases and 67 cases respectively, the latter were pathological negative margin chosen from the former. Immunohistochemisty was used to detect the expression of eIF4E and p53 proteins. Results: The rate of pathological, p53 and eIF4E positive margins was 20.2%, 19.4% and 32.8% respectively. The recurrent rate of those with positive margins was higher than that of negative margins, which including pathological margin (70.6% vs 35.1%, P =0.0000), p53 margin (69.2% vs 33.3%, P =0.018) and eIF4E margin (63.6% vs 28.9%, P =0.018); The survival rate of those with negative margins was higher than those with positive margins, including pathological margin (the 5-year cumulative survival rate was 37.52% and 64.37% respectively, P =0.0023), p53 margin (the 5-year cumulative survival rate was 24.62% and 75.69% respectively, P =0.0012) and eIF4E margin (the 5-year cumulative survival rate was 43.31% and 77.52% respectively, P =0.0006). Conclusion: The prognosis of those with both pathological and molecular positive margins was worse than that of the negative margins; Both the eIF4E and p53 were useful markers to pick out the poor prognostic patients from those with pathological negative margin, and the former seemed to be more potential.展开更多

Methods： The expression of K-ras in human laryngeal squamous cell carcinoma cell lines （Hep-2） and human pancreatic carcinoma cell lines （MIAPaCa-2） was detected by using RT-PCR. Results： The expression of K-ras mRNA in Hep-2 and MIAPaCa-2 was strong and positive. Conclusion： The expression of K-ras mRNA in human laryngeal squamous cell carcinoma cell lines （Hep-2） is positive. Development of laryngeal carcinoma might be related to the activation of K-ras gene point mutation.展开更多

目的研究血清CC型趋化因子2(CC type chemotactic factor 2,CCL2)、CCL18与声门型喉癌患者临床病理参数和预后的关系。方法选择邯郸市中心医院和河北工程大学附属医院2015年8月~2018年12月收治的168例声门型喉癌患者为研究对象,受试者...目的研究血清CC型趋化因子2(CC type chemotactic factor 2,CCL2)、CCL18与声门型喉癌患者临床病理参数和预后的关系。方法选择邯郸市中心医院和河北工程大学附属医院2015年8月~2018年12月收治的168例声门型喉癌患者为研究对象,受试者工作特征(ROC)曲线确定血清CCL2、CCL18最佳截点,将患者分为CCL2高表达组和低表达组、CCL18高表达组和低表达组,分析血清CCL2、CCL18水平与声门型喉癌患者临床病理参数的关系,采用Kaplan-Meier曲线和Log-Rankχ^(2)检验分析血清CCL2高表达组和低表达组、CCL18高表达组和低表达组的5年无病生存率,采用Cox回归模型分析声门型喉癌预后的影响因素,并分析血清CCL2和CCL18表达与肿瘤复发/转移的关系。结果根据ROC曲线计算得出CCL2、CCL18的最佳截点分别为100.81、218.99 pg/ml。相较于CCL2、CCL18低表达组,CCL2、CCL18高表达组T3~T4a级、N1~N3级、肿瘤低分化占比明显升高(P<0.05)。168例声门型喉癌患者随访5年失访8例,完成随访160例。67例发生复发/转移,39例因复发/转移而死亡,肿瘤复发/转移率为41.88%(67/160),无病生存率为58.13%(93/160)。Kaplan-Meier生存曲分析显示,血清CCL2、CCL18高表达组5年无病生存率均明显低于血清CCL2、CCL18低表达组(P<0.05)。Cox回归分析显示,T分级升高、颈淋巴结复发、N分级升高、咽喉部复发、CCL2高表达、CCL18高表达是声门型喉癌预后不良的危险因素(P<0.05)。分析血清CCL2和CCL18表达与肿瘤复发/转移的关系发现,CCL2和CCL18均高表达时其复发/转移率明显高于CCL2和CCL18均低表达、CCL2低表达且CCL18高表达、CCL2高表达且CCL18低表达,差异比较有统计学意义(χ^(2)=10.450,P=0.015)。结论声门型喉癌患者血清CCL2、CCL18高表达与T分级、N分级、肿瘤低分化和预后不良显著相关。展开更多
