Oncologic Outcomes of Surgery Versus SBRT for Non-Small-Cell Lung Carcinoma: A Systematic Review and Meta-analysis. Clin Lung Cancer 2020; 22:e235-e292. [PMID: 32912754 DOI: 10.1016/j.cllc.2020.04.017] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2020] [Revised: 04/21/2020] [Accepted: 04/25/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND The optimal treatment of stage I non-small-cell lung carcinoma is subject to debate. The aim of this study was to compare overall survival and oncologic outcomes of lobar resection (LR), sublobar resection (SR), and stereotactic body radiotherapy (SBRT). METHODS A systematic review and meta-analysis of oncologic outcomes of propensity matched comparative and noncomparative cohort studies was performed. Outcomes of interest were overall survival and disease-free survival. The inverse variance method and the random-effects method for meta-analysis were utilized to assess the pooled estimates. RESULTS A total of 100 studies with patients treated for clinical stage I non-small-cell lung carcinoma were included. Long-term overall and disease-free survival after LR was superior over SBRT in all comparisons, and for most comparisons, SR was superior to SBRT. Noncomparative studies showed superior long-term overall and disease-free survival for both LR and SR over SBRT. Although the papers were heterogeneous and of low quality, results remained essentially the same throughout a large number of stratifications and sensitivity analyses. CONCLUSION Results of this systematic review and meta-analysis showed that LR has superior outcomes compared to SBRT for cI non-small-cell lung carcinoma. New trials are underway evaluating long-term results of SBRT in potentially operable patients.

J Cell Physiol 2020; 235:9399-9413.

Abstract
p120-catenin (p120) serves as a stabilizer of the calcium-dependent cadherin-catenin complex and loss of p120 expression has been observed in several types of human cancers. The p120-dependent E-cadherin-β-catenin complex has been shown to mediate calcium-induced keratinocyte differentiation via inducing activation of plasma membrane phospholipase C-γ1 (PLC-γ1). On the other hand, PLC-γ1 has been shown to interact with phosphatidylinositol 3-kinase enhancer in the nucleus and plays a critical role in epidermal growth factor-induced proliferation of oral squamous cell carcinoma (OSCC) cells. To determine whether p120 suppresses OSCC proliferation and tumor growth via inhibiting PLC-γ1, we examined effects of p120 knockdown or p120 and PLC-γ1 double knockdown on proliferation of cultured OSCC cells and tumor growth in xenograft OSCC in mice. The results showed that knockdown of p120 reduced levels of PLC-γ1 in the plasma membrane and increased levels of PLC-γ1 and its signaling in the nucleus in OSCC cells and OSCC cell proliferation as well as xenograft OSCC tumor growth. However, double knockdown of p120 and PLC-γ1 or knockdown of PLC-γ1 alone did not have any effect. Immunohistochemical analysis of OSCC tissue from patients showed a lower expression level of p120 and a higher expression level of PLC-γ1 compared with that of adjacent noncancerous tissue. These data indicate that p120 suppresses OSCC cell proliferation and tumor growth by inhibiting signaling mediated by nuclear PLC-γ1.

Prognostic and clinicopathological significance of downregulated E-cadherin expression in patients with non-small cell lung cancer (NSCLC): a meta-analysis. PLoS One 2014; 9:e99763. [PMID: 24978478 PMCID: PMC4076188 DOI: 10.1371/journal.pone.0099763] [Citation(s) in RCA: 43] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2014] [Accepted: 05/19/2014] [Indexed: 12/21/2022] Open
Abstract
Background Many studies have investigated the prognostic role of E-cadherin in patients with NSCLC; however, the result still remains inconclusive. An up-to data system review and meta-analysis was necessary to give a comprehensive evaluation of prognostic role of E-cadherin in NSCLC. Methods Eligible studies were searched in Pubmed, Embase and Web of Science databases. The inclusion criteria were studies that assessed the relationship between E-cadherin expression detected by immunohistochemistry (IHC) and the prognosis or clinicopathological features in patients with NSCLC. Subgroup analysis according to race, percentage of reduced/negative E-cadherin expression, histological type, and sample size were also conducted. Odds ratio (OR) or hazard ratio (HR) with 95% confidence interval (CI) were calculated to examine the risk or hazard association. Results A total of 29 studies including 4010 patients were qualified for analysis. The analysis suggested that downregulated E-cadherin expression was significant associated with unfavorable overall survival (OS) and disease-free survival/progression-free survival (DFS/PFS) in patients with NSCLC. Subgroup analysis by race, percentage of reduced/negative E-cadherin expression, sample size also found the significant association in OS. When only the stage I NSCLC were considered, downregulated E-cadherin expression still had an unfavorable impact on OS. Additionally, downregulated E-cadherin expression was significantly associated with differentiation grade, lymphnode metastasis, vascular invasion, and TNM stage. Conclusion Downregulated E-cadherin expression detected by IHC seems to correlate with tumour progression and could serve as an important prognostic factor in patients with NSCLC.

Abstract
Forkhead box M1 (FOXM1), a member of the Fox family of transcriptional factors, is considered to be an independent predictor of poor survival in many solid cancers. However, the underlying mechanism is not yet clear. The aim of the present study was to investigate the clinical significance of the correlation between FOXM1 and epithelial-mesenchymal transition (EMT) in non-small cell lung carcinoma and the possible mechanism responsible for FOXM1-induced EMT and metastasis. In the present study, expression levels of FOXM1 and EMT indicator proteins were determined by tissue microarray (TMA) and immunohistochemical staining, western blotting and reverse transcription-PCR (RT-PCR). Other cellular and molecular approaches including gene transfection, small interfering RNA (siRNA), and migration and invasion assays were utilized. Our results demonstrated that FOXM1 overexpression was statistically significantly associated with a higher TNM stage (p=0.036), lymph node metastasis (p=0.009) and a positive smoking history of the patients (p=0.044). Additionally, high expression of FOXM1 correlated with loss of E-cadherin expression (p<0.001) and anomalous immunopositivity of Vimentin (p=0.002). Moreover, patient survival analysis demonstrated that high expression of FOXM1 (p=0.043) and the presence of lymph node metastasis (p=0.042) were independent prognostic factors for non-small cell lung cancer (NSCLC). Furthermore, various in vitro experiments indicated that overexpression or knockdown of FOXM1 expression altered EMT through activation or inhibition of the AKT/p70S6K signaling pathway. Collectively, the results suggest that FOXM1 may be used as a prognostic indicator for patients with NSCLC and promotes metastasis by inducing EMT of lung cancer cells through activation of the AKT/p70S6K pathway. Therefore, we suggest that FOXM1 may be a potential target for lung cancer therapy.

Abstract
We try to identify the relationship between immunohistochemical marker expression and lymph node involvement in a cohort of 282 patients followed for 5 years after curative resection for NSCLC. In 189 patients (67%), lymph nodes were unaffected while 93 patients (33%) showed nodal involvement. The expression of 15 molecular markers was determined from each patient by tissue-array immunohistochemistry. Univariate analysis indicated significantly higher expression of E-cadherin, γ-catenin, p27, and p53 in patients with lymph node involvement. In those with unaffected nodes, p16 and Rb were expressed. E-cadherin expression was related to a 50% mortality reduction in patients with node involvement (hazard ratio (HR) 0.5; p = 0.017). c-erbB-2 expression was correlated with a 3.4-fold increase in mortality compared to patients without expression of this marker in subjects without node involvement (HR 3.41; p = 0.017). Multivariate analysis identified c-erbB-2 (HR 2.22; p = 0.089) and p27 (HR 1.44; p = 0.019) as prognostics of mortality while Rb (HR 0.74) indicated a good prognosis. The expression of proteins encoded by oncogenes and tumor suppressor genes was different according to lymph node involvement. The increased mortality related to c-erbB-2 expression in patients with unaffected lymph nodes would suggests a need for adjuvant treatment.

Abstract
Respiratory conditions such as chronic obstructive pulmonary disease (COPD) are associated with a greater risk for lung cancer (LC). Oxidative stress and inflammation are involved in LC pathophysiology. Studies conducted so far have focused solely on lung tumor parenchyma and not the airways. We explored levels of local and systemic oxidative stress and inflammation within normal bronchial epithelium and blood of patients with lung cancer (n=52), with and without COPD, and in control subjects (COPD and non-COPD, n=21). In normal bronchial epithelium specimens (bronchoscopy) and blood from patients with similar smoking history (LC-COPD and LC) and control subjects (both COPD and non-COPD), redox balance and inflammatory markers were measured (ELISA and immunoblotting). All subjects were clinically evaluated. Absence of malignant cells within the bronchial specimens was always pathologically confirmed. Bronchial levels of protein carbonylation, MDA-protein adducts, antioxidants, TNF-α, interferon-γ, TGF-β, and VEGF and blood levels of superoxide anion, oxidatively damaged DNA and proteins, TNF-α, interferon-γ, TGF-β, VEGF, and neutrophils were significantly greater in all LC patients compared to control subjects. Systemic levels of oxidatively damaged DNA, superoxide anion, and TNF-α and bronchial levels of TGF-β and TNF-α showed high sensitivity and specificity for LC among patients. Regardless of the presence of an underlying respiratory condition (COPD), protein oxidation, oxidatively damaged DNA, and inflammation were remarkably increased in the normal airways and blood of patients with LC. Furthermore, the potential predictive value for LC development of these molecular events warrants attention and should be explored in future larger longitudinal studies.

Abstract
BACKGROUND AND OBJECTIVE Studies suggest that hypoxia-inducible factor 1α (HIF-1α) expression favours expression of vascular endothelial growth factor A (VEGF-A) involving cellular proliferation, angiogenesis, and metastasis in different cancers including lung cancer. We investigated the correlation of HIF-1α and VEGF-A with clinicopathologic parameters and clinical outcomes in surgically resected non-small cell lung cancer patients. PATIENTS AND METHOD Prospective study to analyze the expression of VEGF-A and HIF-1α with real time-polymerase chain reaction in 66 patients operated on non-small cell lung cancer. RESULTS Mean age was 62.7±9.8 and male:female ratio was 7.3:1. According to the new 2009 TNM classification, stage i, ii, and iii included 27 (40.9%), 21 (31.8%) and 18 (27.3%) patients, respectively. Histological subtypes were: 47% squamous cell carcinoma, 33.3% adenocarcinoma, and 19.7% others. Mean follow-up time was 42.3 months. Median survival was 43.2 months and 5-year overall survival was 42.4%. There was no correlation between HIF-1α and VEGF-A (P=.306). The overexpression of VEGF-A was found more frequent in advanced stage and in lymph nodes metastasis (P=.034 and P=.059, respectively). In multivariate analysis, T descriptor and VEGF-A overexpression were independent prognostic factors (odds ratio [OR]=2.37, P=.016, and OR=2.51, P=.008, respectively). HIF-1α overexpression showed an OR=0.540, but without statistical significance (P=.172). CONCLUSIONS The present study revealed that VEGF-A overexpression was an adverse independent prognostic factor. On the contrary, HIF-1α overexpression showed a tendency to a protective effect on survival of surgically treated non-small cell lung cancer patients, although without statistical significance.

Abstract
BACKGROUND The prognostic significance of the tumor microenvironment, which is created by both cancer cells and cancer-associated fibroblasts (CAFs), has been increasingly recognized. The purpose of this study was to analyze the prognostic markers of stage I squamous cell carcinoma (SqCC), with special reference to the immunophenotypes of both cancer cells and CAFs. METHODS A total of 142 patients with stage I SqCC were included in this study. We examined the expressions of E-cadherin, laminin-5, podoplanin, c-MET, carbonic anhydrase IX (CA-IX), CD10, and CD44 in the cancer cells and those of podoplanin, CA-IX, CD10, and CD44 in the CAFs to evaluate their prognostic value. RESULTS Patients with low E-cadherin expression in the cancer cells showed a significantly poorer prognosis than those with high E-cadherin expression in the cancer cells ( P , .001). On the other hand, high podoplanin expression in the CAFs was also associated with a significantly poorer prognosis ( P , .001). A multivariate analysis identified low E-cadherin expression in the cancer cells and high podoplanin expression in the CAFs as significantly independent prognostic factors for overall survival ( P 5 .013 and P 5 .0011, respectively). According to subgroup analyses combining E-cadherin expression in cancer cells and podoplanin expression in CAFs, 5-year overall survival of patients with low E-cadherin expression in the cancer cells and high podoplanin expression in the CAFs was 7.0% and showed a significantly poorer prognosis as compared with other groups ( P , .001). CONCLUSIONS The current study indicates that immunophenotypes of CAFs could have a prognostic value independent of those of the cancer cells in SqCC.

Abstract
The present study investigated expression profiles of the potential CSC markers including CD133, CD44, ALDH1, and β-catenin, and evaluated their prognostic value in lung adenocarcinomas. One-hundred-and-seventy-seven tumors (stage I) were immunohistochemically examined for the expression of these markers, and thresholds to subdivide expression levels were determined using receiver operating characteristics curves. Tumors with high levels of CD133 (adjusted hazard ratio (HR) 4.55 (95% confidence interval (CI) 1.26-16.40, P = 0.021), CD44 (HR 3.73, 95% CI 1.20-11.58, P = 0.023) or ALDH1 (HR 3.61, 95% CI 1.09-12.3, P = 0.036), but not β-catenin (HR 2.43, 95% CI 0.59-10.8, P = 0.220), showed a significantly higher risk of recurrence than the corresponding low expressers. In conclusion, levels of CD133, CD44, and ALDH1 had independent prognostic value to predict the recurrence of lung adenocarcinoma.

Abstract
Lung cancer is the leading cause of cancer death in the world and metastasis is an essential aspect of lung cancer progression. ITGB8 has been implicated in metastasis of human tumors. However, the molecular mechanism by which ITGB8 is involved in tumor metastasis is still unclear. In this study, we compared the gene expression profiles of human lung cancer cell lines A549 and PC9 by ITGB8 gene silencing with that of parent cells and negative control cells to comprehensively investigate ITGB8-mediated changes with respect to the metastatic potential and gene expression of human lung cancer cell lines. Our results showed that ITGB8 silencing cells exhibited significant cell cycle arrest and less adhesion and invasion abilities. We confirmed by Western blot, ELISA, and real-time PCR that the expression of metastasis-related genes CXCL1, CXCL2, CXCL5, MMP-2, and MMP-9 were significantly decreased while that of E-Cadherin and cystatin B were dramatically increased in A549- and PC9-ITGB8 silencing cells. Furthermore, silencing of ITGB8 caused Snail and NF-κB transcriptional activation, and MEK and Akt phosphorylation level changes in lung cancer cell lines. Our results indicated that ITGB8 may play an important role in metastasis of human lung cancer cells. The ITGB8 silencing may change the lung cancer cells to a less invasive phenotype through alteration in the expression of metastasis-related genes.

Abstract
Cigarette smoke condensate (CSC) has been reported to elicit morphological and transcriptional changes that suggest epithelial-to-mesenchymal transition (EMT) in cultured bronchial epithelial cells. The transdifferentiation potential of acute and prolonged CSC exposure alone or in combination with the β-catenin inhibitor, FH535, was investigated in the bronchial epithelial cell line, BEAS-2B, through assessment of cell morphology, transcript expression, protein expression, and protein localization. Changes in morphology, β-catenin translocation, E-cadherin expression, metalloproteinase expression, and fibronectin could be demonstrated independent of molecular or physiological evidence of EMT. FH535 was shown to increase CSC-induced cytotoxicity and depress β-catenin expression. However, FH535 effects were not limited to the β-catenin pathway as it also blocked the expression of early growth responsive protein 1 (EGR-1) target genes, fibronectin and phosphatase and tensin homologue, without affecting EGR-1 nuclear accumulation.

The effect of TTF-1 expression on ipsilateral mediastinal nodal (N2) metastases in primary adenocarcinoma of the lung. Contemp Oncol (Pozn) 2012; 16:516-9. [PMID: 23788938 PMCID: PMC3687458 DOI: 10.5114/wo.2012.32484] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2012] [Revised: 07/23/2012] [Accepted: 08/07/2012] [Indexed: 01/16/2023] Open
Abstract
Aim of the study To study the effect of thyroid transcription factor-1 (TTF-1) expression on ipsilateral mediastinal nodal (N2) metastases in primary adenocarcinoma of the lung. Material and methods The patients operated on with a diagnosis of primary adenocarcinoma of the lung were retrospectively analyzed and divided into two groups according to their TTF-1 expression. The relationship between TTF-1 expression and N2 metastases was evaluated. Results There were 73 patients (58 male, 15 female) with a mean age of 58.4 ±10.2 in the study group. Sixty-six lobectomies or pneumonectomies and mediastinal lymph node dissection, and seven mediastinoscopies were performed. Positivity of the TTF-1 protein expression detected by the immunohistochemical staining of the specimens was present in 33 patients (45.2%); these patients were classified as group A and the rest of the patients as group B. Eleven patients had N2 disease in group A versus five patients in group B and the difference between the two groups was statistically significant. Conclusions Patients with primary adenocarcinoma of the lung having TTF-1 expression are more likely to have N2 disease. They might be considered as candidates for adjuvant therapy.
