    • 摘要: 目的:探讨极光激酶( Aurora A)、Ki⁃67、p53和p21 WAF1在行根治术非小细胞肺癌( NSCLC)患者预后中的价值。方法采用免疫组化检测Aurora A、Ki⁃67、p53和p21 WAF1在58例NSCLC根治术后患者中的表达情况,分析各指标的表达与患者临床病理特征及预后的关系。结果Aurora A、Ki⁃67、p53和p21 WAF1在NSCLC中的阳性率分别为89.7%(52/58)、53.4%(31/58)、46.6%(27/58)和34.5%(20/58)。 Aurora A高表达患者的淋巴结转移率为69.2%,高于低表达者(37.8%, P=0.045)。 Aurora A低表达组和高表达组患者的3年生存率分别为75.0%和46.0%,差异有统计学意义( P=0.039)。 Aurora A高表达和p53阳性组、Aurora A高表达或p53阳性组、Aurora A低表达和p53阴性组患者的3年生存率分别为40.0%、65.0%和82.1%,差异有统计学意义( P=0.039)。 Cox多因素分析结果显示,Aurora A和p53联合检测为影响NSCLC患者预后的独立因素( P=0.015)。结论Aurora A和p53为影响 NSCLC 患者预后的不良因素,与 p53突变相关的 Aurora A 高表达为影响NSCLC患者预后的独立不良因素。%Objective The aim of this study was to investigate the prognostic value of combined expression of Aurora A, Ki⁃67, p53 and p21 WAF1 in patients after curative resection of non⁃small cell lung cancer(NSCLC). Methods Expressions of Aurora A, Ki⁃67, p53 and p21 WAF1 in 58 tumor samples from resected primary NSCLCs were detected by immunohistochemistry. The correlation of proteins, survival and clinicopathological characteristics was analyzed. Results The positive rates of Aurora A, Ki⁃67, p53 and p21 WAF1 expression were 89.7% (52/58), 53.4% (31/58), 46.6% (27/58) and 34.5% (20/58), respectively. Aurora A expression was positively correlated with nodal metastasis(69.2% vs. 37.8% , P=0.045). The univariable analysis showed that the overall survival ( OS) was 75. 0%in patients with low Aurora A expression and 46.0% in patients with high Aurora A expression ( P=0.039) . The 3⁃year survival rate was 40.0% in patients with positive expression of Aurora A and p53, 65.0% in the patients with positive expression of Aurora A or p53, and 82. 1% in the patients with negative expression of Aurora A and p53 ( P=0. 039 ) . The Cox regression model showed that combined expression of Aurora and p53 is an independent factor affecting the prognosis of NSCLC patients ( P=0. 015 ) . Conclusions Our findings suggest that the positive expression of Aurora A, Ki⁃67 and p53 proteins is an unfavorable factor affecting the prognosis for NSCLC patients, and the overexpression of Aurora A is an independent unfavorable factor association with shorter OS in NSCLC patients. Detection of positive Aurora A and p53 expression may be a useful predictive prognostic indicator for NSCLC patients.

    • 摘要: Objective To investigate the correlation between biological behavior and expression of P27KIP1, P21WAF1 and Bax in gastrointestinal stromal tumors. Methods Immunohistochemical method was used to detect P27KIP1, P21WAF1 and Bax expression in 55 cases of GIST, which were compared among benign GIST, potential malig-nant GIST, and malignant GIST. Results In 55 cases of GIST, the positive expression rates of P27KIP1, P21WAF1 and Bax were 36.3%, 54.5%, 60%. The expression rate of P21WAF1 and Bax were 21.4%, 28.6% in benign GIST, which were significantly increased in potential malignant GIST and malignant GIST. The expression rate of P27KIP1 in benign GIST (64.3%) was significantly higher than that in potential malignant GIST (21.4%) and malignant GIST (29.6%). The expression rate of P27KIP1, P21WAF1 and Bax showed statistically significant difference between benign GIST and po-tential malignant GIST, malignant GIST, but showed no statistically significant difference between potential malignant GIST and malignant GIST. The expressions of P27KIP1, P21WAF1 and Bax showed no correlation with age, sex, location, size, necrosis and histological scheme, but they were related with the malignant progression. Conclusion The low ex-pression of P27KIP1, the high expression of P21WAF1 and Bax are closely related to clinical malignant potential of GIST.%目的:探讨P27KIP1、P21WAF1和Bax在胃肠道间质瘤中的表达及其与临床生物学行为的相关性。方法采用免疫组化法检测P27KIP1、P21WAF1和Bax在胃肠道间质瘤中的阳性表达情况,并在良性组、潜在恶性组、恶性病例组之间进行比较。结果55例胃肠道间质瘤中,P27KIP1、P21WAF1和Bax的阳性表达率分别为36.3%、54.5%、60%。P21WAF1、Bax在良性组的表达分别为21.4%、28.6%,而在潜在恶性组、恶性组明显增高。P27KIP1在良性组的表达率为64.3%,明显高于潜在恶性组、恶性组(21.4%、29.6%)。P27KIP1、P21WAF1和Bax三者在潜在恶性组、恶性组的表达与良性组比较差异有统计学意义,而潜在恶性组与恶性组之间差异无统计学意义。P27KIP1、P21WAF1和Bax的表达与胃肠道间质瘤患者的性别、年龄、部位、肿瘤大小、有无坏死、组织学分型无关,而与其恶性潜能分级相关。结论 P27KIP1的低表达、P21WAF1和Bax的高表达与胃肠道间质瘤临床恶性潜能密切相关。
