Objective To investigate the efficacy and toxicity of chemotherapy of modified INP regimen in the treatment of adenocarcinoma with brain metastases. At the same time,to explore the relationship between expression of β-tubulin-Ⅲ in NSCLC biopsies and sensitivity to this modified INP regimen. Methods The clinical data of 15 adenocarcinoma with brain metastases patients who had been admitted to the first affiliated hospital of Guangzhou medical university from April 2010 to January 2013 were retrospectively analyzed. All patients received modified INP regimen.RECIST 1.0 was taken to know the result. Results For brain metastasis of the 15 patients, complete response (CR) and partial response(PR) were 1 and 5 patients, respectively. 4 patients were stable disease (SD) and progression disease(PD) in 5 patients. The overall response rate(ORR) was 40% and the disease control rate(DCR) was 66.7%. The toxicity was mild. Furthermore, we found NSCLC patients with low β-tubulin-Ⅲexpression had better ORR than those with high expression. Conclusion The modified INP regimen is effective and well-tolerable for brain metastases of adenocarcinoma. The β-tubulin-Ⅲ expression may be associated with the efficacy of this regimen.

神经元特异性烯醇化酶(neuron-specific enolase, NSE)是糖酵解途径中一种重要的同工酶;特异性位于神经元和神经内分泌细胞中。小细胞肺癌(small cell lung cancer,SCLC)细胞浆内含有神经内分泌颗粒,具有神经内分泌分化的特征,为恶性程度高的神经内分泌系统肿瘤。因此,NSE是SCLC诊断中最敏感的肿瘤标志物,在SCLC的临床诊断、治疗、预后均有重要应用价值,科学合理联合检测肿瘤标记物,将能为临床诊疗工作提供有力的帮助。

目的 回顾性分析支气管肺泡细胞癌(bronchioloalveolar carcinoma,BAC)临床特点,提高早期BAC的确诊率,减少误诊。方法 对2013年—2014年间在我院确诊的BAC病例5例的临床资料进行回顾性分析。结果 5例患者中男4例,女1例,年龄在50～73岁之间,在社区医院均曾误诊为肺炎,所有患者均在我院经支气管镜肺活检后确诊为BAC。结论 BAC是一种较为特殊的肺癌,临床上症状无特异性,极易误诊为普通肺炎。由于BAC预后差,误诊后果严重,对初诊为普通肺炎的患者经常规抗感染治疗后临床症状及影像学表现改善不明显时,应及时进行各项检查、明确诊断,以便有效改善患者预后。

Objective To elevate the clinical diagnosis of BAC (bronchioloalveolar carcinoma) so as to reduce misdiagnosis by using retrospective analyses. Methods Retrospective analyses were used to study the five BAC patients, who were diagnosed in our hospital from 2013 to 2014. Results 4 of 5 male, and 1 female, age between 50 and 73, were diagnosed as pneumonia. All of them were made a definite diagnosis as BAC after performing transbronchial lung biopsy. Conclusion BAC is an exceptional lung adenocarcinoma and there is no specific clinic symptom. BAC was easily misdiagnosed as common lung pneumonia. There will be serious consequences after misdiagnosis of BAC due to its poor prognosis. Those patients who were misdiagnosed as common lung disease, but there was no obvious improvement after accepting long anti-infective therapy and there was negatively detection of pathogenic bacteria in them, are needed to perform all other clinical examination to clarify a diagnosis, and to further improve the prognosis of the patients.
