Abstract
This study aimed to explore the prognostic significance of solid pattern for bone metastases (BM) in epidermal growth factor receptor (EGFR)-mutated lung adenocarcinoma patients after surgery. A total of 237 stage I-III lung adenocarcinoma patients with EGFR mutation were analyzed after procedure. The patients were divided into four groups: the solid-present patients with BM, the solid-absent patients with BM, the solid-present patients without BM and the solid-absent patients without BM. The bone disease-free survival (bDFS), systemic disease-free survival (DFS) and overall survival (OS) were assessed. The results revealed that the patients with solid pattern had shorter DFS (15 months vs. 19 months; P < 0.001) and OS (47 months vs. 77 months; P = 0.001). Moreover, bDFS of solid-present patients was significantly shorter than solid-absent patients (27 months vs. 14 months; P < 0.001). In addition, patients with solid component had worsened bDFS, no matter with BM as first-site development (12.5 months vs. 16.5 months; P = 0.016) or non-first-site development (16.5 months vs. 45.5 months; P < 0.001). These findings suggested that solid pattern predicted worse DFS and OS and also showed shortened interval between surgery and BM.

Abstract
OBJECTIVES Central nervous system (CNS) metastases are common complications in epidermal growth factor receptor (EGFR) mutant non-small-cell lung cancer (NSCLC) treated with EGFR-tyrosine kinase inhibitors (TKIs). However, for patients without baseline CNS metastasis, data regarding the incidence of symptomatic CNS metastasis with EGFR-TKI treatment and its risk factors are still rare. MATERIALS AND METHODS Patients with EGFR-mutant advanced NSCLC without baseline CNS metastasis who are receiving first- and/or third-generation EGFR-TKIs were included. Overall survival (OS), cumulative incidence of symptomatic CNS metastasis upon treatment failure, and their risk factors were evaluated. RESULTS There were 813 patients enrolled, with 562, 106, and 32 received first-line gefitinib, erlotinib, and osimertinib, respectively, while 113 received second-line osimertinib. At a median follow-up of 18.1 months, the median OS was 45.5 months. There were 38 patients developed symptomatic CNS metastases. Osimertinib-treated patients tended to have a lower risk of CNS metastases compared with those treated with first-generation EGFR-TKIs (p = 0.059). However, the cumulative incidence curves of symptomatic CNS metastasis tended to reach a plateau after approximately 3 years regardless of which generation was used, and incidences beyond that period were similar in the two groups. Patients with L858R mutation exhibited a higher risk of developing CNS metastasis than patients with 19del mutation (p = 0.001). Interestingly, the presence of baseline neuroimaging was not associated with the risk of developing CNS metastasis or OS. CONCLUSION Compared with first-generation EGFR-TKIs, osimertinib can delay but not prevent the development of symptomatic CNS metastasis. L858R mutation is an independent risk factor for CNS metastasis.

Abstract
OBJECTIVES The aim of this study was to evaluate the impact of the preoperative body mass index (BMI) on the postoperative outcomes in patients with completely resected non-small cell lung cancer (NSCLC). MATERIALS AND METHODS The data of patients with NSCLC in whom R0 resection was achieved were extracted from the database of NSCLC samples accumulated by the Japanese Joint Committee of Lung Cancer Registry in the year 2010, and the surgical outcomes including postoperative morbidity, mortality and the prognosis, were evaluated. RESULTS Among 18,978 registered lung cancer cases, 16,509 patients (9996 men and 6513 women) were extracted. The median of age was 69 years old, and the histologic types included adenocarcinoma (n = 12,029), squamous cell carcinoma (n = 3286), large-cell carcinoma (n = 488) and others. The patients were divided into three groups according to their BMI: normal (BMI 18.5 to <25), underweight (BMI < 18.5) and overweight (BMI ≥ 25). Multivariate logistic regression analyses of factors associated with postoperative morbidity and mortality showed no significant differences among the three groups. In comparison to the normal group, the overall survival (OS) of the underweight group was significantly worse (p < 0.001) while that of the overweight group was marginally better (p = 0.075). A multivariate analysis of factors associated with OS showed that in addition to the age, sex and clinical stage, the preoperative BMI (underweight group vs. normal group: hazard ratio [HR] 1.417 [95% confidence interval {CI}: 1.278-1.572, p < 0.001], overweight group vs. normal group: HR 0.883 [95% CI: 0.806-0.967, p = 0.007]) was an independent prognostic factor. A multivariate analysis for the disease-free survival (DFS) also showed the preoperative BMI to be an independent significant prognostic factor. CONCLUSIONS The preoperative BMI is an independent prognostic factor in patients with completely resected NSCLC. A low preoperative BMI was associated with significantly poor survival in Japan.

Abstract
The efficacy of molecular targeting agents is dependent on the metabolism or nuclear receptor-mediated clearance of chemotherapy resistance-related factors such as cytochrome P450 (CYP) or ATP binding cassette subfamily B member 1 (ABCB1). In this study, we revealed the roles of the microRNA-4271/CAR (constitutive androstane receptor) axis in the regulation of the resistance to molecular anticancer targeting agents in non-small cell lung cancer (NSCLC) cells including two main categories of NSCLC: lung adenocarcinoma (AC) and large cell lung cancer (LCC). The expression of miR-4271 was negatively correlated with CAR expression in NSCLC tissues. MiR-4271 targeted CAR and inhibited the activation of the CAR signaling pathway. Overexpression of CAR in NSCLC enhanced the resistance of NSCLC cells to molecular targeting agents and miR-4271-infected NSCLC cells enhanced their sensitivity to molecular targeting agents such as Gefitinib. The mechanism-data showed that overexpression of miR-4271 decelerated the mechanism or the clearance of molecular targeting agents by targeting the 3'UTR (3' un-translation region). These results suggest that miR-4271 may contribute to the development of more effective strategies for the treatment of advanced NSCLC.

Abstract
Lung cancer (Lca) is one of the malignant tumors with the fastest morbidity and mortality increase and the greatest threat to human health and life. The incidence of non-small cell lung cancer (NSCLC) in the nonsmoking female has increased recently. However, its pathogenesis is still unclear, and there is an urgent need for clinical diagnostic biomarkers, especially for early diagnosis. A nontargeted lipidomic approach based on ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF/MS), as well as two machine learning approaches (genetic algorithm and binary logistic regression) was used to screen candidate discriminating lipids and define a combinational lipid biomarker in serum samples to distinguish female patients with NSCLC from healthy controls. Moreover, the candidate biomarkers were verified by using an external validation sample set. Our result revealed that fatty acid (FA) (20:4), FA (22:0) and LPE (20:4) can serve as a combinational biomarker for distinguishing female patients with NSCLC from healthy control with good sensitivity and specificity. Furthermore, this combinational biomarker also showed good performance in distinguishing early-stage NSCLC female patients from a healthy control. We observed that levels of unsaturated fatty acids clearly decreased, while saturated fatty acids and lysophosphatidylethanolamines pronouncedly increased in Lca patients, compared with the healthy controls, which revealed significant disturbance of lipid metabolism in NSCLC females. Our results not only provide hints to the pathological mechanism of NSCLC in nonsmoking female but also supply a combinational lipid biomarker to aid the diagnosis of NSCLC at early-stage.

Abstract
OBJECTIVES Transforming anaplastic lymphoma kinase (ALK) gene rearrangements are well known as a unique subset of non-small cell lung cancer (NSCLC) with mutations other than EGFR. Currently, crizotinib is the standard first-line treatment for ALK-positive NSCLC. MATERIALS AND METHODS With advances in detection methods, more and more uncommon ALK fusion partners have been identified. Herein we present a novel SOS1-ALK fusion and the efficacy of crizotinib in an advanced NSCLC patient harboring this type of fusion. RESULTS A 52-year-old Chinese man had left upper lobe primary NSCLC and synchronous multiple lung metastases (cT2N3M1, stage IV). The ultrasound-guided fine-needle aspiration cytology of palpable left supraclavicular lymph nodes and the results of immunohistochemistry staining supported the diagnosis of metastatic lung adenocarcinoma. Using a next-generation sequencing assay (NGS), we showed that the tumor had a SOS1-ALK fusion which the breakpoints was (S2, A20) rather than other actionable mutations. Therefore, the patient received first-line crizotinib and experienced a remarkable tumor response and has tolerated crizotinib well until this writing. CONCLUSION Considering this rare SOS1-ALK fusion and remarkable response to an ALK-inhibitor, it is important to be aware of the presence of SOS1-ALK fusions in patients with advanced NSCLC to better guide targeted therapy. Precision methods, such as NGS for oncogenic alteration detection, should also be encouraged in clinical practice.

Abstract
The long noncoding RNA (lncRNA) MIR503HG has been shown to play an important role in cancer development. The aim of the present study was to investigate the potential roles of MIR503HG in the proliferation and apoptosis of non-small cell lung cancer cell (NSCLC). We used short hairpin RNA (shRNA) against MIR503HG to knock down and vector containing full length of MIR503HG to overexpress MIR503HG in NSCLC cells. The expression of MIR503HG in NSCLC tissues and cells was detected and the effects of MIR503HG on the cell proliferation and apoptosis were determined. Results showed that the expression of MIR503HG was significantly upregulated in NSCLC tissues compared with adjacent tissues. We found that downregulation of MIR503HG could clearly suppressed cell proliferation and cell cycle progression. Moreover, MIR503HG knockdown also promoted apoptosis of NSCLC cells. As expected, overexpression of MIR503HG significantly promoted cell proliferation and inhibited cell apoptosis in NSCLC NCI-H1975 cells. We predicted and verified miR-489-3p and miR-625-5p as the direct targets of MIR503HG by bioinformatics analysis and luciferase reporter assay. Mechanically, MIR503HG negatively regulated miR-489-3p and miR-625-5p expressions in NSCLC cells. Moreover, downregulation of miR-489-3p and miR-625-5p weaken the decreased cell proliferation and increased apoptosis of A549 cells after MIR503HG knocking down. In conclusion, knockdown of MIR503HG suppressed proliferation and promoted apoptosis of NSCLC cells through regulating miR-489-3p and miR-625-5p. Our findings of this study suggested that MIR503HG could be a potential therapeutic target for NSCLC development.

Abstract
PURPOSE Locally advanced non-small cell lung cancer (NSCLC) is commonly managed with either definitive chemoradiation (dCRT) or neoadjuvant chemoradiation followed by surgery (nCRT + S). This study sought to compare 30- and 90-day mortality between nCRT + S and dCRT for these patients. METHODS The National Cancer Database was queried (2004-2014) for clinicall staged T1-3N2 or T3-4N0-1 (except T3N0) NSCLC that received nCRT + S or dCRT. Statistics included cumulative incidence analysis of 30- and 90-day mortality (before and following propensity score matching) and Cox proportional hazards regressions. RESULTS Of 28,379 patients, 4063 (14.3%) underwent nCRT-S, and 24,316 (85.6%) dCRT. Of the trimodality patients, 79.2% received lobectomy, 8.2% sublobar resection, and 12.5% pneumonectomy. Trimodality therapy and age, in addition to several soceiodempographic and oncologic variables, were associated with 30- and 90-day mortality. Short-term mortality was significantly higher with nCRT + S compared to dCRT at both 30 (3.4% vs. 0.8%, p < 0.001) and 90days (7.5% vs. 6.6%, p = 0.017), which persisted following propensity matching (3.4% vs. 0.4% and 7.5% vs. 5.3% respectively, both p < 0.001). At both 30 and 90 days, pneumonectomy was associated with higher mortality than lobectomy (6.1% vs. 2.9% and 11.1% vs. 6.9% respectively, both p < 0.001). CONCLUSIONS Treatment with nCRT + S was associated with greater 30- and 90- day post-treatment mortality when compared to treatment with dCRT, with larger differences in observed in 30-day post-treatment mortality. These data may inform shared-decsion making among patients eligible for both aproaches.

Abstract
OBJECTIVES Immune checkpoint inhibitors (ICIs) can cause pneumonitis in lung cancer patients. We aimed to identify the clinical and radiologic characteristics, incidence, and risk factors of ICI-related pneumonitis in patients with non-small cell lung cancer (NSCLC). MATERIALS AND METHODS Medical records and chest computed tomography scans of NSCLC patients treated with an ICI over a 5-year period at a tertiary hospital were retrospectively analyzed. Clinical characteristics were compared between patients with and without ICI-related pneumonitis to identify risk factors. RESULTS Data from 167 eligible patients were analyzed. The incidences of all-grade and grade 3-4 pneumonitis were 13.2% and 4.2%, respectively. The presence of preexisting interstitial lung disease [odd ratio (OR), 6.03; 95% confidence interval (CI), 1.19-30.45; P = 0.030] was associated with a higher incidence of ICI-related pneumonitis. The presence of extrathoracic metastasis [OR, 0.34; 95% CI, 0.13-0.92; P = 0.034] was associated with a lower incidence of ICI-related pneumonitis. The dominant radiologic pattern (72.7%) of ICI-related pneumonitis was organizing pneumonia. Half of the patients with pneumonitis completely recovered or improved; however, the mortality rate was 18.2%. CONCLUSION ICIs should be used with caution when treating lung cancer patients who have underlying chronic lung disease, especially interstitial lung disease.

Abstract
INTRODUCTION BRAFV600E mutations occur in 1-2% of lung adenocarcinomas and act as oncogenic drivers via the mitogen-activated protein kinase (MAPK) pathway. These mutations are mutually exclusive from the more common, epidermal growth factor receptor mutations or anaplastic lymphoma kinase rearrangements and have been associated with poor outcomes and a lower response to platinum-based chemotherapy. Areas covered: Dabrafenib is a potent adenosine-triphosphate-competitive inhibitor of BRAF kinase and is selective for the BRAFV600E mutation in kinase panel screening, cell lines, and xenografts. The efficacy and safety of dabrafenib alone or in combination with the MEK inhibitor trametinib has been demonstrated in a number of clinical trials and herein, we discuss this data and outline the current and future role of BRAF/MEK inhibition in the management of advanced lung cancer. Expert commentary: Responses rates with combination of dabrafenib/trametinib are approximately 63-64% and interestingly occur in both smokers and non-smokers but toxicities require dose reductions in the real world for the majority of patients.

Abstract
Paclitaxel (PTX) is a effectively chemotherapeutic agent which is extensively able to treat the non-small cell lung, pancreatic, breast and other cancers. But it is a practically insoluble drug with water solubility less than 1 μg/mL, which restricts its therapeutic application. To overcome the problem, hyaluronic acid-complexed paclitaxel nanoemulsions (HPNs) were prepared by ionic complexation of paclitaxel (PTX) nanoemulsions and hyaluronic acid (HA) to specifically target non-small cell lung cancer. HPNs were composed of dl-α-tocopheryl acetate, soybean oil, polysorbate 80, ferric chloride, and HA and fabricated by high-pressure homogenization. The HPNs were 85.2 ± 7.55 nm in diameter and had a zeta potential of −35.7 ± 0.25 mV. The encapsulation efficiency was almost 100%, and the PTX content was 3.0 mg/mL. We assessed the in vivo antitumor efficacy of the HPNs by measuring changes in tumor volume and body weight in nude mice transplanted with CD44-overexpressing NCI-H460 xenografts and treated with a bolus dose of saline, Taxol®, PTX nanoemulsions (PNs), or HPNs at a dose of 25 mg/kg. Suppression of cancer cell growth was higher in the PN- and HPN-treated groups than in the Taxol® group. In particular, HPN treatment dramatically inhibited tumor growth, likely because of the specific tumor-targeting affinity of HA for CD44-overexpressed cancer cells. The loss of body weight and organ weight did not vary significantly between the groups. It is suggest that HPNs should be used to effective nanocarrier system for targeting delivery of non-small cell lung cancer overexpressing CD44 and high solubilization of poorly soluble drug.

Abstract
BACKGROUND Lung cancer is the leading cause of cancer-related death worldwide. In addition to surgical resection, which is considered first-line treatment at early stages of the disease, chemotherapy and radiation are widely used when the disease is advanced. Of multiple responses that may occur in the tumor cells in response to cancer therapy, the functional importance of autophagy remains equivocal; this is likely to restrict current efforts to sensitize this malignancy to chemotherapy and/or radiation by pharmacological interference with the autophagic response. SCOPE OF REVIEW In this review, we attempt to summarize the current state of knowledge based on studies that evaluated the function of autophagy in non-small cell lung cancer (NSCLC) cells in response to radiation and the most commonly used chemotherapeutic agents. MAJOR CONCLUSIONS In addition to the expected prosurvival function of autophagy, where autophagy inhibition enhances the response to therapy, autophagy appears also to have a "non-cytoprotective" function, where autophagy blockade does not affect cell viability, clonogenicity or tumor volume in response to therapy. In other cases, autophagy may actually mediate drug action via expression of its cytotoxic function. GENERAL SIGNIFICANCE These observations emphasize the complexity of autophagy function when examined in different tumor cell lines and in response to different chemotherapeutic agents. A more in-depth understanding of the conditions that promote the unique functions of autophagy is required in order to translate preclinical findings of autophagy inhibition to the clinic for the purpose of improving patient response to chemotherapy and radiation.

Abstract
Epidermal growth factor receptor (EGFR) is a non-small-cell lung cancer biomarker, based on which several near-patient-testing methods have been developed and applied to predict treatment response on individual patients. Existing methods for detection of EGFR mutation are costly, labor-intensive and time-consuming. In this paper, we report a novel EGFR mutation testing system, which is based on Mach-Zehnder Interferometer (MZI) sensor and isothermal solid-phase DNA amplification (IDA) technique, called MZI-IDA sensor system. The system can deliver results within 30 min and shows high sensitivity to detect trace amounts of genomic DNA (<1 copy). In addition, the system is able to detect a L858R mutation in a 99:1 mixture of wild-type and mutant cells. In a pilot clinical study, the system is compared with conventional methods (PCR and direct sequencing) by using tissue biopsy samples from NSCLC patients. The MZI-IDA sensor system is proved to be capable of fast and accurate detection of the L858R mutation of EGFR gene in clinical samples. This may greatly help the clinicians develop an appropriate treatment plan.
