    Background and objective Brain metastases are common in non-small-cell lung cancer (NSCLC) and the prognosis is poor. Erlotinib is a specific inhibitor of the epidermal growth factor receptor-associated tyrosine kinase (EGFRTKI), which has been gradually used in the treatment for advanced NSCLC. The aim of this study is to evaluate the antitumor efficacy and its relevant factors of erlotinib in NSCLC patients with brain metastases. Methods The clinical data of 30 NSCLC patients with brain metastases were reviewed retrospectively. All of them were treated with erlotinib, given orally 150mg daily. These patients discontinued administration of erlotinib until disease progression, death or intolerable side effects. Results In terms of intracranial lesions, partial response (PR) was observed in 2 patients (6.7%), with stable disease (SD) in 17 patients (56.7%), for overall disease control rate (DCR) of 63.4%. As for systemic disease, PR was observed in 2 patients (6.7%), with SD in 5 patients (16.7%), for overall DCR of 23.4%. There was no statistical difference in DCR among different subtypes of age, gender, smoking history, histology, PS score, the number of brain metastases, the onset of brain metastases, chemotherapy, brain radiotherapy and side effects. The median time to disease progression (MTTP) and median survival time (MST) was 2.4 months and 7.7 months respectively. The 1 and 2 year survival rate was 38.4% and 15.2%. The univariate analysis showed that the survival time was related to the patients’ PS score, smoking history, brain radiotherapy and chemotherapy. The multivariate analysis indicated that brain radiotherapy was the independent prognostic factor and the relationship between the survival time and smoking history was near to statistical significance. Conclusion The patients receiving brain radiotherapy may have better survival benefit. Non-smokers have a trend to survive longer than smokers. Erlotinib may be effective on brain metastases in NSCLC patients and appears to be a possible new treatment option

    本文以海岸带小城镇海岸线建筑后退距离为研究对象,在借鉴国内外相关经验的基础上,提出以多因素分析法代替单一因素分析法确定海岸线建筑后退距离的基本思路,并重点探讨了不同海岸底质下多因素分析法对于海岸线建筑后退距离的影响。文章以福建省若干海岸带小城镇为例,就海岸线建筑后退距离的确定方法初步进行了实例研究。On the basis of relevant experience at home and abroad, the paper takes the coastal building setback of coastal small towns as research object, discusses the calculation and control method of multiple-factor analysis instead of single-factor analysis. And then it explains the impact of multiple-factor analysis on how to calculate coastal building setback under different coastal sediments. At last, the paper develops methods for empirical research, taking several coastal small towns in Fujian province as example.厦门大学校长基金资助项目:海岸带及海岛小城镇总体规划的技术与方法研究资

    Background and objective At present non-small cell lung cancer (NSCLC) is still the leading cause of death induced by cancer. The aim of this study is to investigate the prognostic factors of advanced NSCLC. Methods Total 1,742 cases of stage IV NSCLC data from Jan 4, 2000 to Dec 25, 2008 in Shanghai Chest Hospital were collected, confirmed by pathological examinations. Analysis was made to observe the impact of treatment on prognosis in gender, age, smoking history, pathology, classification, clinical TNM stage. Survival rate, survival difference were evaluated by Kaplan-Meire method and Logrank test respectively. The prognosis were analyzed by Cox multivariate regression. Results The median survival time of 1,742 patients was 10.0 months (9.5 months-10.5 months). One, two, three, four, and five-year survival rates were 44%, 22%, 13%, 9%, 6% respectively. The median survivals of single or multiple metastasis were 11 months vs 7 months (P < 0.001). Survival time were different in metastasic organs, with the median survival time as follows: lung for about 12 months (11.0 months-12.9 months), bone for 9 months (8.3 months-9.6 months), brain for 8 months (6.8 months-9.1 months), liver, adrenal gland, distannt lymph node metastasis for 5 months (3.8 months-6.1 months), and subcutaneous for 3 months (1.7 months-4.3 months). The median survival times of adenocarcinoma (n=1,086, 62%) and squamous cell carcinoma cases (n=305, 17.5%) were 12 months vs 8 months (P < 0.001). The median survival time of chemotherapy and best supportive care were 11 months vs 6 months (P < 0.001); the median survival times of with and without radiotherapy were 11 months vs 9 months (P=0.017). Conclusion Gender, age, gross type, pathological type, clinical T stage, N stage, numbers of metastatic organ, smoking history, treatment of advanced non-small cell lung cancer were independent prognostic factors
