Growing evidence has underscored long non-coding RNAs (lncRNAs) serving as potential biomarkers for cancer prognosis. However, systematic tracking of a lncRNA signature for prognosis prediction in non-small cell lung cancer (NSCLC) has not been accomplished yet. Here, comprehensive analysis with differential gene expression analysis, univariate and multivariate Cox regression analysis based on The Cancer Genome Atlas (TCGA) database was performed to identify the lncRNA signature for prediction of the overall survival of NSCLC patients. A risk-score model based on a 14-lncRNA signature was identified, which could classify patients into high-risk and low-risk groups and show poor and improved outcomes, respectively. The receiver operating characteristic (ROC) curve revealed that the risk-score model has good performance with high AUC value. Multivariate Cox’s regression model and stratified analysis indicated that the risk-score was independent of other clinicopathological prognostic factors. Furthermore, the risk-score model was competent for the prediction of metastasis-free survival in NSCLC patients. Moreover, the risk-score model was applicable for prediction of the overall survival in the other 30 caner types of TCGA. Our study highlighted the significant implications of lncRNAs as prognostic predictors in NSCLC. We hope the lncRNA signature could contribute to personalized therapy decisions in the future.

Abstract Background leptomeningeal metastasis (LM) is a devastating scenario in patients with non-small cell lung cancer (NSCLC), with an estimated median overall survival (OS) of 4–6 months from diagnosis. Several studies have clarified the prognosis of treatment modalities after LM. However, just a few studies have clarified the prognosis of LM patterns. We evaluate the prognosis based on various patterns of LM under multidisciplinary treatment (MDT). Method This retrospective study evaluated NSCLC patients treated at National Taiwan University Hospital between 2007–2019 with brain metastases (BM) and LM. LM was classified into LM only, LM concurrent with BM, and LM after BM. Treatments including systemic therapy, whole-brain radiotherapy (WBRT), stereotactic radiosurgery (SRS), and intrathecal chemotherapy with Methotrexate (IT MTX) were recorded. BM excision was done by a neurosurgeon using minimally invasive neurosurgery. The MDT was done according to patients’ clinical situations. Kaplan-Meier methodology was used to describe overall survival OS. Multivariate Cox regression model was used to access prognostic factors. Result One hunderd patients with NSCLC CNS metastasis was included in this study. Median OS in patients with single, oligo and multiple BM was 42.0 months (95% CI= 0.12–83.89), 58.1 months (95% CI= 13.00–103.26), and 21.3 months (95% CI= 16.93–25.73), respectively. The median OS of all LM patients was 9.8 months. The median OS of LM after BM, concurrent BMLM, and LM only was 8 months (95% CI= 2.58–13.56), 41.5 months (95% CI= 0.00–94.36), and 18.5 months (95% CI=3.68–33.32), respectively. Multivariate Cox regression analysis showed only IT MTX (p= 0.010, HR= 0.392, 95%CI= 0.19–0.80) was associated with survival. Conclusion MDT in the TKI era has led to a dramatic improvement of OS in patients with LM (4–6 months vs. 9.8 months). NSCLC patients with LM only and concurrent BM LM has a better prognosis and longer survival, and thus are worth receiving intensive MDT care.

Abstract Background: In the present study, we sought to detect the expression of secreted fizzled-related protein-1 (SFRP1) and investigate its role in the progression and prognosis of patients with non-small cell lung cancer (NSCLC). Methods: The expression of SFRP1 at both mRNA and protein level were examined by quantitative real-time polymerase chain reaction (qRT-PCR) and Immunohistochemistry analysis, respectively. The relationship between SFRP1 expression and clinical factors of patients with NSCLC was analyzed by chi-square test. Transwell assay was conducted to determine the influences of SFRP1 on migratory and invasive of NSCLC cells. Kaplan-Meier analysis was used to describe the overall survival of NSCLC patients. Cox regression analysis was conducted to estimate the prognostic value of SFRP1 in NSCLC.Results: The expression of SFRP1 was down-regulated in NSCLC tissues compared to that in adjacent normal controls both at mRNA and protein level (P<0.05). And the low SFRP1 expression was related to the distant metastasis, vascular invasion and TNM stage. The overexpression of SFRP1 in vitro significantly inhibited the migration and invasion of NSCLC cells. The overall survival of patients with high SFRP1 expression was was proved to be longer than those with low expression (log rank test, P<0.001). In addition, univariate and multivariate analyses suggested that SFRP1 was an independent prognostic molecule marker for NSCLC patients. Conclusion: Taken together, our findings indicated that the decreased of SFRP1 could influence the cell migration and invasion as well as be regarded as an independent prognostic marker in NSCLC.

Abstract Backgrounds: Astrocyte-elevated gene-1 (AEG-1) functions as an oncogene and regulates angiogenesis in non-small cell lung cancer (NSCLC). In this prospective study, we assessed the values of plasma AEG-1 mRNA expression by liquid biopsy associated with tumor response and survival in NSCLC patients treated with pemetrexed. Methods: Patients diagnosed advanced NSCLC were enrolled to be treated with pemetrexed combined platinum as first-line chemotherapy. All patients underwent blood sampling before any cancer treatment (C0) and at first response evaluation after two cycles (C2) treatments. Response to chemotherapy and survival were assessed. Plasma mRNA was extracted from peripheral blood mononuclear cell (PBMC) and quantification of RNA was performed by real-time PCR.Results: A total of 50 patients with advanced NSCLC were included and 13 of 50 patients combined with bevacizumab. In patient groups of SD (n = 13) and PD (n = 10), the plasma mRNA of AEG-1, thymidylate synthase (TS) and CK19 were elevated significantly at C2 compared to patients in treatment response group (PR, n = 27) (PR v.s. SD or PD, AEG-1: 1.22 ± 0.80 v.s. 4.51 ± 15.45, p = 0.043). NSCLC patients had elevated AEG-1 (AEG-1 ≥ 2) after 2-cycle chemotherapy had shorter PFS and OS (high AEG-1 v.s. low AEG-1, median, PFS: 5.5 v.s. 11.9 months, p = 0.021; OS: 25.9 v.s. 40.8 months, p = 0.019, respectively). In Cox regression analysis, increased plasma mRNA expression of AEG-1indicated poor prognosis in survival.Conclusion: Circulating mRNA concentration of AEG-1 could be a predictive and prognostic biomarker in NSCLC patients treated with pemetrexed. Increased expression of AEG-1 contributed to the chemoresistance and caused lung cancer progression.

18211 Background: Prognostic factors identified in advanced non small cell lung cancer are: age, gender, PS, h. SWOG univariable analysis in patients with chemotheraphy; confirmed these factors and show a relationship between the hemoglobin level and the overall survival; in addition the metastasic site number and cisplatin- based chemotheraphy (7). To analyse and compare the hemoglobin level before cisplatin- based chemotheraphy with survival in patients with advanced non- small cell lung cancer. Methods: Retrospective study conducted at the IONC of the 179 clinical record were analized, over a 5 year period. The collected data were: age, gender, PS, histologic type, stage, chemotheraphy cycles number, smooke history, number and metastasic site. We analyzed median and overal survival using Kaplan Meier, and the anemia as a prognostic implication factor with univariable and multivariable Cox regression analysis. Istologic type and TNM (1–6). Results: The mean age was 59 (40–79); 146 (81.5%) male and 33 (18.5%) women; histological types found were squamous cell carcinomas in 66 (37%), and adenocarcinoma in 113 (63%); stage IIIB in 61 (34%) and IV in 118 (66%). 147 (82%) were smokers and 32 (18%) were never smokers. All the patients had PS 0–1. Median overall survival time was 11.53 months and 13.88 months in the haemoglobin level < or > 11 gr/ 100 ml, respectively. (p=0.3). In univariable Cox regression analysis, smoking rates and chemotheraphy cycles number were predictors of survival (p=0.05 y p=0.018, respectively). Hemoglobine (p=0.55). In multivariable Cox regression analysis, only the number of cycles was predictor of survival (p=0.026). Hemoglobine (p=0.34). Conclusions: In our experience, a greater survival tendency was observed in patients with advanced non- small cell lung cancer who presented levels of Hemoglobine greater than 11 gr/dl, previous to cisplatin- based chemotherapy without statistical significance.

Non-small cell lung cancer (NSCLC) is a leading cause of death worldwide. The upregulation of the epidermal growth factor receptor (EGFR) due to mutations has been observed in a number of cancers, and tyrosine kinase inhibitors (TKIs), such as gefitinib and erlotinib, which specifically target EGFR signaling, have been used to treat NSCLC patients. The presence of EGFR mutations was previously shown to confer sensitivity to TKIs. In this study, we evaluated the correlation between EGFR mutations and response to erlotinib in Chinese NSCLC patients. We recruited 36 patients with stage IIIB/IV NSCLC who had failed first-line chemotherapy, and treated them with erlotinib. We used immunohistochemistry to determine EGFR expression, and we screened for mutations using PCR analysis. We used Cox regression analysis and Kaplan-Meier curves for survival analysis. We found that 8 patients had exon 19 mutations, while 3 patients had exon 21 mutations. An Eastern Cooperative Oncology Group (ECOG) grade of 2 was a significant negative predictor of overall survival (OS). Patients with EGFR mutations showed a significantly better OS compared to those without EGFR mutations. Additionally, multivariate analysis showed that erlotinib-treated stage IV patients had a significantly longer progression-free survival (PFS) compared to stage IIIB patients. Patients with EGFR mutations also had a significantly better PFS compared to those without EGFR mutations. The overall remission rate (22.2%) and disease control rate (75%) were significantly higher compared to the rates after second-line chemotherapy (<10%). In conclusion, the presence of EGFR mutations could be a marker to predict the therapeutic efficacy of erlotinib and the prognosis in Chinese NSCLC patients.

Abstract Background Dissociated responses (DR) are phenomena in which some tumors shrink, whereas others progress during treatment of patients with cancer. The purpose of the present study was to evaluate the frequency and prognosis of DR in non-small cell lung cancer (NSCLC) patients treated with anti-program cell death-1/ligand 1 (anti-PD-1/L1) inhibitors. Methods This retrospective study included NSCLC patients who received anti-PD-1/L1 inhibitor as second- or later-line treatment. We excluded patients without radiological evaluation, including brain imaging within 28 days prior to the treatment, and those without measurable lesions. We evaluated all measurable lesions in each organ. We defined DR as a disease with some shrinking lesions as well as growing or emerging new lesions in patients who showed progressive disease (PD), according to the RECIST 1.1 at the initial CT evaluation. Cases not classified as DR were defined as ‘true PD’. Overall survival was compared between patients with DR and those with true PD using Cox proportional hazards models. Results The present study included 62 NSCLC patients aged 27–82 years (median: 65 years). DR and true PD were observed in 11 and 51 patients, respectively. Nivolumab, pembrolizumab, and atezolizumab were administered to 45, 7, and 10 patients, respectively. Median overall survival was significantly longer in patients with DR versus true PD (14.0 vs. 6.6 months; hazard ratio for death: 0.40; 95% confidence interval: 0.17–0.94). Conclusions The frequency of DR in NSCLC patients who showed PD to anti-PD-1/L1 was 17.7%. Patients with DR exhibited a relatively favorable prognosis.

Abstract Background Studies have indicated that individuals taking aspirin have a reduced risk of cancers and have also established chemo-preventive benefit of aspirin in colorectal cancer. However, research on the association between aspirin use and the survival in patients with lung cancer has revealed inconsistent results. In this study, we investigated the effect of aspirin use on the survival of inoperable non-small cell lung cancer (NSCLC) patients. Methods We identified a cohort of 38,842 patients diagnosed with NSCLC between 2000 and 2012 using the Taiwan’s National Health Insurance Research Database and used propensity score matching to reduce possible confounding factors. In total, 9864 patients (4932 matched pairs) were included in the matched cohort. Aspirin exposure was analyzed to identify a possible association with mortality in patients with inoperable NSCLC. Time-dependent Cox regression models were used to calculate the hazard ratios (HRs) and the 95% confidence intervals (95% CIs) that corresponded with aspirin exposure. Results A total of 4979 patients used aspirin at the time of diagnosis of NSCLC. The median overall survival (OS) of the aspirin users was 1.73 (interquartile range, 0.94–3.53) years compared with the 1.30 (interquartile range, 0.69–2.62) years of the non-aspirin users. The Cox proportional hazard model with the time-dependent covariate revealed that aspirin use was associated with a significantly longer OS (HR: 0.83, 95.0% CI: 0.80–0.86). After controlling the sociodemographic characteristics (age, sex, income, and level of urbanization) and lung cancer treatments by propensity score matching, the aspirin users still had a significantly longer OS than the non-aspirin users (HR: 0.79, 95.0% CI: 0.75–0.83). Conclusion Aspirin use is associated with a longer OS in patients with inoperable NSCLC, suggesting that aspirin has a potential anticancer effect. These results warrant further randomized clinical trials to evaluate the actual role of aspirin in the treatment of NSCLC patients.
