背景与目的:表皮生长因子受体(epidermal growth factor receptor,EGFR)和血管内皮生长因子受体(vascular endothelial growth factor receptor,VEGFR)均属酪氨酸激酶受体(receptor tyrosine kinase,RTK),可调控细胞的增殖、分化与生存... 背景与目的:表皮生长因子受体(epidermal growth factor receptor,EGFR)和血管内皮生长因子受体(vascular endothelial growth factor receptor,VEGFR)均属酪氨酸激酶受体(receptor tyrosine kinase,RTK),可调控细胞的增殖、分化与生存。BAD是Bcl-2家族中的促凋亡信号成分,在调控细胞凋亡特别是肿瘤细胞凋亡过程中发挥重要作用。但目前人们对上述这些重要蛋白在非小细胞肺癌(non-small-cell lung cancer,NSCLC)中的表达与肿瘤病理学的关系所知甚少。本研究探讨ECFR、VEGFR、BAD和磷酸化BAD在NSCLC中的表达情况以及与肿瘤病理的关系。方法:使用组织微阵列(tissue microarray,TMA)切片的免疫组织化学法,NSCLC患者51例(26例腺癌,16例鳞癌,8例大细胞癌,1例大细胞神经内分泌癌)。结果:51例患者中EGFR和VEGFR分别在10例(20%)和14例(27%)中出现过度表达。大细胞癌中未见VEGFR表达(0/8例),而鳞癌和腺癌患者中VEGFR表达分别为44%(7/16)和27%(7/26)。EGFR和VEGFR的表达与性别,肿瘤细胞分化及肿瘤浸润程度(包括胸膜浸润,血管浸润,淋巴结转移,肺内播散,脑转移情况)无关。51例患者中22例(43%)出现BAD蛋白表达缺失,且NSCLC的不同病理类型间差异有显著性。BAD蛋白表达缺失在16例鳞癌患者中10例(63%),8例大细胞癌患者中5例(63%),26例鳞癌患者中有7例(27%)(P=0.04)。51例患者中25例(49%)出现磷酸化BAD蛋白过度表达[其中26例腺癌患者中有13例(50%),16例鳞癌患者中有8例(50%),8例大细胞癌患者中有4例(50%)]。BAD蛋白的表达缺失与磷酸化BAD蛋白的过度表达经统计检验与上述肿瘤浸润程度无相关性。结论:肺鳞癌出现VEGFR表达增高的可能较大,而大细胞癌出现VEGFR表达增高的可能最小。在鳞癌和大细胞癌中可见BAD蛋白表达的显著缺失。NSCLC患者EGFR,VEGFR,磷酸化BAD蛋白的过度表达以及BAD蛋白表达的缺失与病理浸润程度无关。但这些受体酪氨酸激酶表达以及与NSCLC凋亡直接相关的媒介因子可能成为未来多靶向治疗中的候选靶标。 展开更多

Objective:To present clinical and pathologic features of pulmonary hyalnizing granuloma through analyzing three cases found in our institution and reviewing cases reported in the English language literature.Methods and Results:Three cases of pulmonary hyalnizing granuloma identified at our institution during the past ten years were reviewed. In the first case,the patient presented with concurrent pulmonary hyalinizing granuloma and histoplasmosis. In the second case,the patient presented with a 5.5 cm lung mass and a separate smaller lesion radiologically resembling bronchogenic carcinoma. There was very prominent polyclonal lymphocytic proliferation at the periphery especially of the smaller lesion likely representing an early stage of the disease process. In the third case,the patient presented with multiple subpleural plaque-like lesions in addition to nodular lesions of the lung. All cases also demonstrated various degrees of lymphocytic infiltration within the lesions. The English literature has been reviewed through searching the PubMed.Conclusion:Since patients with pulmonary hyalinizing granuloma demonstrated a spectrum of clinical presentations,radiologic changes and histologic features with a variety of associated clinical disorders,pulmonary hyalnizing granuloma is more in keeping with a clinicopathologic entity rather than a specific pathologic disease. 展开更多
