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.

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.

       目的   探讨CT、MRI影像学表现对原发性肝细胞癌（HCC）微血管侵犯（MVI）的诊断价值。方法   选取2018年1月—2024年7月江门市第二人民医院（江门市中心医院蓬江分院）和江门市中心医院120例（共158个病灶）HCC患者，均行上腹部CT、MRI平扫+增强及弥散加权成像（DWI）检查；以术后病理结果为金标准。比较CT、MRI平扫+增强及DWI对HCC MVI诊断效能；分析HCC MVI诊断中CT、MRI平扫+增强及DWI检查与术后病理确诊结果之间的一致性；比较HCC MVI与无HCC MVI患者影像学表现及表观扩散系数（ADC）值。结果    DWI检查对HCC MVI的诊断效能（灵敏度、特异度、准确度、阳性预测值、阴性预测值）均显著性高于CT、MRI平扫+增强（P＜0.05）；CT、MRI、DWI对原发性肝细胞癌患者微血管侵犯的诊断效能比较，差异均无统计学意义（P＞0.05）。在HCC MVI诊断效能中，CT、MRI影像学表现与术后病理确诊结果之间为中度一致性；DWI与术后病理确诊结果之间为高度一致性。HCC MVI患者的强化方式在非边缘动脉期强化、强化包膜、晕状强化、结中结、门脉分支癌栓占比均显著性高于无HCC MVI患者（P＜0.05）。在不同b值（400、800、1 000、1 500 s/mm² ）下，HCC MVI患者的ADC值均显著性高于无HCC MVI患者（P＜0.05）。结论    CT、MRI平扫+增强及DWI对HCC MVI均具有较好的诊断效能，而MRI诊断结果与病理诊断一致性更佳，尤其DWI图中ADC值可更加精准地判断HCC的患者是否发生微血管侵犯，有助于指导临床医生建立“个体化”精准诊疗策略。
