中文摘要:
      目的:为探究不同病理类型的肺磨玻璃结节(ground-glass opacity, GGO)中ki-67 的表达情况及其与肺癌相关标志物p53、 p63、EGFR 等表达的相关性。方法:收集从2012 年10 月至2014 年10 月我院胸外科收治的254 例GGO病人的临床病史、影像、 病理及血常规等资料予以回顾性分析。结果:Ki-67表达量从良性组(n=66),不典型腺瘤样增生(atypical adenomatous hyperplasia, AAH, n=27),到原位癌(adenocarcinoma in situ, AIS, n=11),微浸润腺癌(minimally invasive adenocarcinoma, MIA, n=108),最后到 浸润性腺癌(invasive adenocarcinoma, IAC, n=42)即随着早期肺癌的演进过程不断增高。Ki-67 与各标志物的相关系数为0.386 (p53, P<0.001)、0.227(EGFR, P=0.024)、0.441(CEA, P<0.001)。通过ROC 曲线分析得到ki-67 来判别良恶性GGO 的曲线下面积 和最佳阈值,也得到了早期肺癌演进过程中ki-67 阈值变化。恶性GGO 组全血细胞中平均单核细胞含量低于良性组GGO,且差 异有统计学意义。结论:ki-67 表达量在不同病理类别的GGO中有显著性差异,且在肺癌演进过程中依次增高,可作为鉴别早期 肺癌不同病理类型的参考依据和预后因子;ki-67 与P53、EGFR 及CEA的表达具有一定的相关性。
英文摘要:
      Objective:To explore the expression of ki-67 in the GGO of different pathology and try to find whether the correlation of ki-67 with P53, EGFR and CEA.Methods:The clinical history, CT information, white blood cell count and pathology material of 254 cases with GGO during 2012 and 2014 were collected and analyzed retrospectively.Results:The expression level of ki-67 was gradually increased fromBenign group (n=66), AAH (n=27), AIS (n=11), MIA (n=108), to IAC (n=42) , which is exactly the evolution progression of early lung adenocarcinoma; The correlation coefficient were 0.386 (p53, P<0.001), 0.227(EGFR, P=0.024) and 0.441 (CEA, P<0.001) respectively; By ROC curve analysis, we got the AUC and optimal cut-off points of ki-67 with regarding to differentiation of GGO and the variation of thresholds along the progression of early lung adenocarcinoma; The number and the percentage of blood monocyte of the patients with malignant GGO were lower than these of benign group.Conclusion:There are significant differences among GGOs of different pathologic categories with respect to the expression of ki-67 that gradually increased in the early lung adenocarcinoma progression. To some extent, a positive correlation of ki-67 with P53, EGFR and CEA exists.
