病理学切缘和以p53与eIF4E为指标的分子切缘预测喉癌患者预后

目的探讨病理学切缘和以p53、eIF4E为指标的分子切缘在预测喉癌患者预后中的价值。方法选择了253例喉癌患者进行病理学切缘研究，在以上病理学阴性切缘中选择67例，应用免疫组化方法检测p53、eIF4E蛋白的表达以进行分子切缘研究。结果1．病理学切缘、p53切缘、eIF4E切缘的阳性率分别是20．2％，19．4％和32．8％；2．阳性切缘患者的复发率高于切缘阴性者，包括病理学切缘(70．6％vs35．1％，P=0．0000)、p53切缘(69．2％vs33．3％，P=0．018)、eIF4E切缘(63．6％vs28．90A，P=0．018)；而切缘阳性者5年累积生存率低于切缘阴性者，包括病理学切缘(37．52％vs64．37％，P=0．0023)、p53切缘(24．62％vs75．69％，P=0．0012)、eIF4E切缘(43．31％vs77．52％，P=0．0006)。结论病理学切缘和以p53、eIF4E为指标的分子切缘阳性者的预后比切缘阴性者差，而p53和eIF4E可以从病理学切缘阴性者中发现预后更差的患者，并且eIF4E可能是优p53的分子指标。

The Prognostic Value of Pathological and Molecular Margins Marked by p53 and elF4E in Laryngeal Carcinoma

Objective: To study the prognostic value of the pathological margin and molecular margin marked by eIF4E and P53 protein in laryngeal carcinoma. 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.
