Objective. To examine the relationship between the Sirtuin-3 (SIRT3) expression and the clinical indicators/prognosis of patients with non-small-cell lung cancer (NSCLC). Methods. The mRNA level of SIRT3 was detected by real-time PCR, while the protein level was detected by Western blot and immunohistochemical staining. SPSS 16.0 software was used for statistical analysis. Results. The expression of SIRT3 was significantly higher in NSCLC tissue than in adjacent tissue. The SIRT3 level was correlated significantly with lymph node metastasis and clinical stage of NSCLC patients. Moreover, univariate analysis showed that the expression of SIRT3, tumor size, lymph node metastasis, degree of differentiation, and clinical stage were correlated with the prognosis of NSCLC patients. Multivariate analysis demonstrated that lymph node metastasis, the tumor size, and SIRT3 expression were independent prognostic factors for NSCLC patients. Conclusions. SIRT3 is associated with the development and progression of NSCLC. The SIRT3 expression can be used as an independent prognostic factor for NSCLC patients and help identify prognosis of NSCLC. Therefore, SIRT3 has the potential to become a new factor for prognosis prediction and personalized treatment of NSCLC.

Abstract Background: Non-small cell lung cancer (NSCLC) is a disease with quite grave prognosis. This study explored the diagnostic efficiency of miR-126-5p and miR-34c-3p in serum extracellular vesicles (EVs) in NSCLC patients.Methods: Serum EVs were extracted from NSCLC patients and healthy people and verified. The expression of miR-126-5p and miR-34c-3p in serum EVs were tested. Correlation of miR-126-5p and miR-34c-3p expression and diagnosis, prognosis and pathological characteristics (age, gender, tumor size, clinical stage, and lymph node metastasis) of NSCLC patients was analyzed. The downstream targets of miR-126-5p and miR-34c-3p were predicted and their roles in diagnosis and prognosis of NSCLC patients were evaluated.Results: miR-126-5p and miR-34c-3p were poorly expressed in serum EVs of NSCLC patients and their low expressions were associated with clinical stage, lymph node metastasis and prognosis of NSCLC patients and could be used as biomarkers for diagnosis. As the common target genes of miR-126-5p and miR-34c-3p, LYPLA1 and CDK6 were highly expressed in serum EVs and were associated with poor prognosis in NSCLC patients.Conclusion: Lowly expressed miR-126-5p and miR-34c-3p in serum EVs of NSCLC patients can serve as biomarkers for diagnosis and are linked with prognosis. As common targets of miR-126-5p and miR-34c-3p, LYPLA1 and CDK6 are also associated with poor prognosis in NSCLC patients.

BackgroundFor different lymph node metastasis (LNM) and distant metastasis (DM), the diagnosis, treatment and prognosis of T1-2 non-small cell lung cancer (NSCLC) are different. It is essential to figure out the risk factors and establish prediction models related to LNM and DM.MethodsBased on the surveillance, epidemiology, and end results (SEER) database from 1973 to 2015, a total of 43,156 eligible T1-2 NSCLC patients were enrolled in the retrospective study. Logistic regression analysis was used to determine the risk factors of LNM and DM. Risk factors were applied to construct the nomograms of LNM and DM. The predictive nomograms were discriminated against and evaluated by Concordance index (C-index) and calibration plots, respectively. Decision curve analysis (DCAs) was accepted to measure the clinical application of the nomogram. Cumulative incidence function (CIF) was performed further to detect the prognostic role of LNM and DM in NSCLC-specific death (NCSD).ResultsEight factors (age at diagnosis, race, sex, histology, T-stage, marital status, tumor size, and grade) were significant in predicting LNM and nine factors (race, sex, histology, T-stage, N-stage, marital status, tumor size, grade, and laterality) were important in predicting DM(all, P< 0.05). The calibration curves displayed that the prediction nomograms were effective and discriminative, of which the C-index were 0.723 and 0.808. The DCAs and clinical impact curves exhibited that the prediction nomograms were clinically effective.ConclusionsThe newly constructed nomograms can objectively and accurately predict LNM and DM in patients suffering from T1-2 NSCLC, which may help clinicians make individual clinical decisions before clinical management.

AbstractObjectives: As the member of the Fox family of transcription factors, Forkhead box M1 (FoxM1) is known to be critical in pathogenesis and development of many solid tumors. However, the clinical value and expression pattern in non-small cell lung cancer (NSCLC) is still poorly understood. Methods: In this study, real-time PCR was mainly applied to examine the gene expression levels of FoxM1 in 120 pairs of clinical NSCLC tissues, which were classified into different groups according to smoking status, lymph node metastasis, and tumor grade. By utilizing the online Kaplan-Meier plotter, overall survival analysis was performed to study the correlation between FoxM1 expression and prognosis of lung cancer (LC) patients. Afterwards, the correlation of FoxM1 gene expression and the clinical pathological parameters was examined by κ2 test in these 120 NSCLC patients. Results: FoxM1 was found to be aberrantly upregulated in NSCLC patients, and its overexpression was correlated to groups designated as smokers, cases of positive lymph node metastasis and cases of advanced tumor grades. Online survival analysis showed that high expression of FoxM1 predicted shorter overall survival of NSCLC patients. Additionally, FoxM1 upregulation was statistically correlated with positive smoking history, lymph node metastasis and higher tumor grades. Conclusion: FoxM1 is overexpressed in cancerous tissues and is associated with the poor prognosis of NSCLC patients. Our results provide insights into the utility of FoxM1 as an important biomarker and prognostic factor for NSCLC.

Background: A series of studies have demonstrated that NPAS2 plays a critical role in the development and progression of several cancers. However, the association between genetic variants in the  NPAS2 gene and the clinical outcome of patients with non-small-cell lung cancer (NSCLC) has not been investigated. Methods: Six functional SNPs in NPAS2 were selected and genotyped using the Sequenom iPLEX genotyping system in a cohort of 484 Chinese NSCLC patients undergoing surgery. Multivariate Cox proportional hazards model were used for the prognosis analysis. Results: We found that SNP rs2305158 exhibited a significant association with overall survival of NSCLC patients in the dominant model (hazard ratio [HR]: 0.68; 95% CI: 0.49–0.95; p = 0.02). Lymph node metastasis was significantly associated with increased death risk (HR: 1.73; 95% CI: 1.24–2.40; p = 0.001) in patients with the homozygous wildtype (WW) genotype of rs2305158. However, no significant association was observed between them in patients carrying a heterozygous variant (WV) or homozygous variant (VV) genotype of rs2305158. Finally, in the joint and interaction analysis, the patients carrying homozygous wildtype (WW) genotype and lymph node metastasis from N1 to N3 conferred a significant increased effect on death (HR: 2.29; 95% CI: 1.40–3.76; p = 0.001). Conclusions: Our results suggest that NPAS2 polymorphisms may serve as an independent prognostic marker for NSCLC patients.
