  • Effectiveness and Safety of Nedaplatin Combined with Chemotherapy for Advanced Non-small Cell Lung Cancer: A Meta-Analysis

    Objective To evaluate the effectiveness and safety of nedaplatin combined with chemotherapy versus cisplatin combined with chemotherapy for advanced non-small cell lung cancer (NSCLC). Methods The randomized controlled trials (RCTs) on nedaplatin combined with chemotherapy versus cisplatin combined with chemotherapy for advanced NSCLC were searched in The Cochrane Library, PubMed, EMbase, CBM, VIP and WanFang Data from the date of their establishment to January 2012. According to the inclusion and exclusion criteria, two reviewers independently screened the studies, extracted the data and assessed the quality. Then RevMan 5.0 software was used for meta-analysis. Results A total of 15 RCTs involving 1 076 patients were included. The results of meta-analysis showed that, compared with the cisplatin combined with chemotherapy, nedaplatin combined with chemotherapy could reduce the risks of nausea and vomiting (RR=0.56, 95%CI 0.48 to 0.65, Plt;0.000 01), decrease the risk of renal function impairment (RR=0.47, 95%CI 0.30 to 0.74, P=0.001), but increase the risk of thrombocytopenia (RR=1.59, 95%CI 1.20 to 2.11, P=0.001). There were no significant differences between the two groups in objective response rate (ORR) (RR=1.09, 95%CI 0.92 to 1.29, P=0.03), leukopenia (RR=1.05, 95%CI 0.92 to 1.19, P=0.50), and hemoglobin reduction (RR=0.92, 95%CI 0.80 to 1.07, P=0.30). Conclusion Compared with cisplatin combined with chemotherapy for advanced NSCLC patients, nedaplatin in combination with chemotherapy can significantly reduce the risks of nausea, vomiting and renal function impairment. Although the ORRs are similar in the two groups, nedaplatin combined with chemotherapy can cause a higher risk of thrombocytopenia. For the quality restriction and possible publication bias of the included studies, more high quality RCTs are required to further verify this conclusion.

  • Combined Inhibition of Epidermal Growth Factor and Cyclooxygenase-2 Signaling Pathways in Non-small Cell Lung Cancer Therapy

    The resistance of non-small cell lung cancer (NSCLC) to epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) has been brought into focus. COX-2 signal pathway was found to be closely related to EGFR signal pathway by recent researches, and there has been a growing interest to focus the researches on whether COX-2 pathway inhibition improves the efficacy of EGFR-TKIs in treating advanced NSCLC. In this review, we will illustrate recent advances of combined inhibition of EGFR and COX-2 signal pathways in NSCLC therapy.

  • Effectiveness of Adjuvant Chemotherapy with Complete Resection for Non-small Cell Lung Cancer

    Objective To assess the effectiveness of adjuvant chemotherapy with complete resection for non-small cell lung cancer. Methods We searched MEDLINE (1966 ~ 2005 ), EMBASE (1984-2005 ), The Cochrane Library (Issue 2,2005 ), CBMdisc (1979-2005 ), CNKI (1994-2005 ), VIP (1989-2005 ), CMCC (1994-2005 ) and Wanfang Database with key words of non-small cell lung cancer or NSCLC and adjuvant chemotherapy, to identify randomized control trials (RCTs) of platinum-based adjuvant chemotherapy plus complete resection versus complete resection alone for non-small cell lung cancer patients. Two reviewers evaluated the quality of literature independently. Then we conducted meta-analysis using RevMan 4.2.7 software. Results We identified 9 RCTs and did not carry out pool analysis for the difference of chemotherapy regimens between the studies. The results of three studies showed that 5 years' mortality of adjuvant chemotherapy group was lower than that of surgery group alone. The results of the other 6 studies showed there was no statistical difference in 5 years' mortality between the adjuvant chemotherapy plus surgery and surgery alone groups. Conclusions The effectiveness of some adjuvant chemotherapy regimens with complete resection in patients with non-small cell lung cancer has been improved. But the number of each chemotherapy regimen RCT is too small and with poor quality. So more multi-center RCTs with a larger sample size and high quality are needed.

  • Evidence-based Treatment for a Patient of Ⅱ B Stage Non-Small Cell Lung Cancer

    Objective To report evidence-based treatment for 2 case of Ⅱ B stage non-small cell lung cancer. Methods We searched systematic reviews and randomized controlled trials in The Cochrane Library (Issue 2, 2009), MEDLINE (PubMed, January 1970 to June 2009) and ACP Journal Club (1996 to June 2009), and evaluated the evidence. Results The best clinical evidence for Ⅰ and Ⅱ stage non-small cell lung cancer patients showed that in the patients with resectable nonsmall cell lung cancer, postoperative adjuvant radiotherapy and chemotherapy could not improve survival compared with surgery alone. We did not find evidence which indicated that preoperative chemotherapy improved survival in people with resectable non-small cell lung cancer. Conclusion In accordance with the wishes of the patient and family, they do not accept the radiotherapy and chemotherapy, but choose palliative and supportive therapy.

  • Expressions of Livin,Caspase-3, Bcl-2 in Lung Tissue of NSCLC and their Prognostic Significances

    Objective To study the expressions of Livin, Caspase-3 and Bcl-2 in lung tissue of nonsmall cell lung cancer ( NSCLC) , and their relationship with the clinicopathological features and prognosis of NSCLC. Methods The expressions of Livin, Caspase-3 and Bcl-2 proteins were evaluated by immunohistochemical method in 87 NSCLC samples and 40 lung benign tissues. The relationship of their expressions with the clinicopathological features and prognosis of NSCLC were analyzed by Spearman’s Rank correlation and COX Regression. Results More NSCLC tissues showed expression of Livin than lung benign tissues( 72. 41% vs 0. 0% , P = 0. 000 ) , and the expression of Caspase-3 was significantly decreased ( 67. 82% vs 87. 5%, P lt; 0. 05 ) . The proteins of Livin, Caspase-3 and Bcl-2 were detected in the endochylema but none was detected in nucelus. There was no relationship between the expression of each of these proteins and the clinicopathological features of NSCLC such as histologic type, tumor differentiation,lymph node metastasis, TNM stage, the size of tumor, and tumor site. The expression of Livin was correlated with Caspase-3 and Bcl-2 expressions ( r1 = - 0. 260, P = 0. 015; r2 = 0. 351, P = 0. 001) . Livin, Caspase-3 and Bcl-2 were not independent prognostic factors of NSCLC. Conclusions The expression of Livin and Bcl-2 are up-regulated in NSCLC. The expression of Livin is positively correlated with that of Caspase-3 and Bcl-2, they might interact with each other in the carcinogenesis and development of NSCLC. The levels of Livin, BCl-2 and Caspase-3 proteins are not independent factors affecting the prognosis of lung cancer patients.

  • Correlation and Clinical Significance of Estrogen Receptors and Vascular Endothelial Growth Factor in Non-Small Cell Lung Cancer

    Objective To explore the clinical significance of estrogen receptor α( ERα) , estrogen receptor β( ERβ) in non-small cell lung cancer( NSCLC) .Methods EnVision method was used to detect the expressions of ERα, ERβ, vascular endothelial growth factor( VEGF) , and microvessel density( MVD) in 54 NSCLC patients, 10 patients with lung benign lesions, and 10 normal controls. The interrelation between ERα, ERβ, VEGF, and MVD was analyzed. Results No obvious expressions of ERα and ERβwere observed in the normal lung tissues and lung benign lesions. The positive expression rates of ERα, ERβ, and VEGF in NSCLC were 20. 4% ( 11/54) , 64. 8% ( 35/54) , and 64. 8% ( 35/54) , respectively. There were no significant differences between ERαin regard to clinical parameters of NSCLC. But the expression of ERβwas dependent on pathological classification and differentiation of NSCLC. The expression of ERβ was significantly higher in adenocarcinoma than in squamous cell carcinoma( P lt; 0. 05) . The expression rate of ERβin well differentiated group was significantly higher than that in low, moderately differentiated group( P lt;0. 05) . There were significant differences between VEGF in regard to lymph node metastasis and TNM stage. The expression of ERαinterrelated with VEGF and MVD with r value of 0. 4 and 0. 685 respectively ( P lt;0. 05) . There was little correlation between ERβ and VEGF, MVD( P gt; 0. 05) . Conclusion Theexpression of ERβ correlates with pathological classification and differentiation of NSCLC, suggesting its significance in evaluating the pathological classification and malignant degree of NSCLC. The expression of ERαcorrelates with VEGF and MVD, suggesting that ERαpossibly promote micro-angiogenesis of NSCLC by VEGF pathway.
