BackgroundSurviving expression might serve as a prognostic biomarker predicting the clinical outcome of non-small cell lung cancer (NSCLC). The study was conducted to explore the potential correlation of survivin protein expression with NSCLC and its clinicopathologic characteristics.MethodsPubMed, Medline, Cochrane Library, CNKI and Wanfang database were searched through January 2016 with a set of inclusion and exclusion criteria. Data was extracted from these articles and all statistical analysis was conducted by using Stata 12.0.ResultsA total of 28 literatures (14 studies in Chinese and 14 studies in English) were enrolled in this meta-analysis, including 3206 NSCLC patients and 816 normal controls. The result of meta-analysis demonstrated a significant difference of survivin positive expression between NSCLC patients and normal controls (RR = 7.16, 95 % CI = 4.63-11.07, P < 0.001). To investigate the relationship of survivin expression and clinicopathologic characteristics, we performed a meta-analysis in NSCLC patients. Our results indicates survivin expression was associated with histological differentiation, tumor-node-metastasis (TNM) stage and lymph node metastasis (LNM) (RR = 0.80, 95 % CI = 0.73-0.87, P < 0.001; RR = 0.75, 95 % CI = 0.67-0.84, P < 0.001; RR = 1.14, 95 % CI = 1.01-1.29, P = 0.035, respectively), but not pathological type and tumor size. (RR = 1.00, 95 % CI = 0.93-1.07, P = 0.983; RR = 0.95, 95 % CI = 0.86-1.05, P = 0.336, respectively).ConclusionHigher expression of survivin in NSCLC patients was found when compared to normal controls. Survivin expression was associated with the clinicopathologic characteristics of NSCLC and may serves as an important biomarker for NSCLC progression.
Surgery is an effective treatment option for bronchiectasis. Sputum volumes lower than 30 mL, negative proof of Gram-negative bacteria and bronchial stump coverage using intercostals muscles or pedicle pleura embedding are the key factors for successful treatment. Special attention has to be given to any complications in elderly patients.
Background Broncholithiasis is a rare disease with various clinical classifications. The aim of this study was to evaluate the imaging diagnosis and surgical treatment of broncholithiasis. Methods and Materials Forty-eight patients with broncholithiasis were enrolled in this retrospective study between January 1985 and December 2009. Patients were classified into intraluminal, transluminal, and extraluminal broncholith according to the anatomy between the calculus and the bronchial lumen confirmed by chest computed tomography (CT), bronchoscopy, and pathology after operation. Result Forty-eight patients were enrolled, with 33 males and 15 females. The sex ratio (male:female) was 2.2:1, and average age was 54.3 ± 13.6 years. There were 8, 19, and 21 patients in intraluminal, transluminal, and extraluminal broncholith group, respectively. Cough, hemoptysis, and chest pain were the most common symptoms. Four patients with intraluminal broncholith and two with transluminal broncholith underwent broncholith removal via bronchoscopy, and the other 42 patients underwent thoracotomy. Conclusion Bronchoscopy combined with CT examination is helpful in diagnosing and typing broncholithiasis. An optimal treatment method, either bronchoscopic removal of broncholithiasis or thoracotomy, according to the clinical typing and indications, is the key to improve the treatment effect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
