Background:: Lung cancer remains the most common cause of cancer-related deaths in China and worldwide. Traditional surgery and chemotherapy do not offer an effective cure although gene therapy may be a promising future alter-native. Kallistatin (Kal) is an endogenous inhibitor of angiogenesis and tumorigenesis. Recombinant adeno-associated virus (rAAV) is considered the most promising vector for gene therapy of many diseases due to persistent and long-term transgen-ic expression. Objective:: The aim of this study was to investigate whether rAAV9-Kal inhibited NCI-H446 subcutaneous xenograft tumor growth in mice. Method:: The subcutaneous xenograft mode were induced by subcutaneous injection of 2×106 H446 cells into the dorsal skin of BALB/c nude mice. The mice were administered with ssrAAV9-Kal (single-stranded rAAV9) or dsrAAV9-Kal (double-stranded rAAV9）by intraperitoneal injection (I.P.). Tumor microvessel density (MVD) was examined by anti-CD34 stain-ing to evaluate tumor angiogenesis. Results:: Compared with the PBS (blank control) group, tumor growth in the high-dose ssrAAV9-Kal group was inhibited by 40% by day 49, and the MVD of tumor tissues was significantly decreased. Conclusion:: The results indicate that this therapeutic strategy is a promising approach for clinical cancer therapy and impli-cate rAAV9-Kal as a candidate for gene therapy of lung cancer.

Corticosteroid Administration

Introduction: Corticosteroids are used to treat immune-related adverse events (irAEs) associated with nivolumab. However, patients with non-small-cell lung cancer who are administered corticosteroids before the initiation of nivolumab treatment are commonly excluded from clinical trials. The appropriate timing for corticosteroid administration in relation to nivolumab treatment, effects of corticosteroids on the efficacy of nivolumab, and resulting adverse events are not clearly understood. In this study, the effects of differences in the timing of corticosteroid administration on nivolumab efficacy and the resulting adverse events were examined. Methods: A retrospective study was conducted with 109 patients who were treated with nivolumab at Sapporo Minami-Sanjo Hospital between December 2015 and March 2018. Results: Of the 109 patients treated with nivolumab, 12 patients were administered corticosteroids before the first cycle of nivolumab (pre-CS), and 33 patients were administered corticosteroids after the first cycle of nivolumab (post-CS). These 2 groups were compared with the control group comprising 64 patients who were not administered corticosteroids (non-CS). The objective response rate in the post-CS group was significantly higher than that in the non-CS group, and the disease control rate in the pre-CS group was significantly lower than that in the non-CS group. The overall survival time and progression-free survival time in the pre-CS group were significantly shorter than those observed in the non-CS group; however, these did not differ from those in the post-CS group. Conclusions: These results suggest that corticosteroids administered to patients with non-small-cell lung cancer after initiation of nivolumab treatment did not affect the disease prognosis. Thus, corticosteroids can be administered immediately for rapid treatment of irAEs.

Objectives: The neutrophil-to-lymphocyte ratio (NLR) is a prognostic marker in patients with cancer receiving immunotherapy. Recent studies have shown that a high NLR was associated with a poor response and decreased survival. However, there is no intervention to reverse abnormally high NLR and improve clinical outcomes. Astragalus polysaccharide injection (PG2) is an immunomodulatory therapy for cancer-related fatigue. This study aimed to examine whether PG2 might normalize the NLR and affect the overall survival of patients with lung cancer treated with immunotherapy. Materials and Methods: We retrospectively examined the medical records of patients with lung cancer treated with immune checkpoint inhibitors (ICIs) between October 1, 2015 and November 30, 2019. All patients received ICI combination chemotherapies, and some similarly received PG2 (Control vs PG2). The NLR was assessed before treatment and 6 weeks after ICI initiation, and the survival data was collected at least 4 years after treatment initiation for the first enrolled patient. Results: Fifty-three patients were included. Six weeks after ICI initiation, 91.3% of the patients in the PG2 group exhibited a predefined “Decrease or no change” in the NLR, which was 28% higher than that in the Control group (63.3%) ( P = .028). The NLR significantly decreased by 31.60% from baseline in the PG2 group ( P = .012), whereas it increased by 5.80% in the Control group ( P = .572). Six weeks after ICI treatment initiation, both groups had a median NLR of 3.73, and the overall survival was also similar (PG2 vs Control, 26.1 months vs 25.4 months, respectively); however, the PG2 group had a higher median baseline NLR than the Control group (PG2 vs Control, 4.51 vs 2.81, respectively). Conclusion: This study demonstrated that PG2 could normalize the NLR in patients with lung cancer receiving ICI combination treatments.

e18617 Background: The study evaluated the prevalence & impact of sarcopenia in gastroesophageal cancer (GC) & lung cancer (LC) patients undergoing resection. Methods: An observational prospective study was conducted in department of surgical oncology, AIIMS, New Delhi. All patients aged under 65 years with resectable GC & LC were included. Skeletal muscle index (SMI) using cross-sectional CT images at the level of L3 & Hand grip strength (dynamometer) were used to assess sarcopenia. Random benign patients with CT images were used as control group. Patients were categorized into sarcopenic and non-sarcopenic and outcome parameters were compared. Results: In the study population (n = 66), GC & LC constituted 44 (66.67%) & 22(33.33%) respectively. Mean age was 53.4 years. The prevalence of sarcopenia based on the combined method (CT imaging & handgrip strength) was 57.58%, CT based sarcopenia was 33.34% & handgrip strength-based sarcopenia was 43.93%. Mild and moderate sarcopenia was seen in 37.88% (n = 25) & 19.7 % (n = 13) respectively. Among patients with GC, prevalence of sarcopenia was 59.09% by combined method, 36.36% and 43.18% by CT based method alone & handgrip strength-based method alone respectively. Among LC prevalence of sarcopenia was 54.54% by combined method, 27.27% and 45.45% by CT based & handgrip-based method. The concordance between CT muscle mass & grip strength was 62.12%. Most female patients had weak handgrip strength despite having normal SMI. In control group (n = 44) mean age was 54.5 years, the prevalence of CT based sarcopenia was 34.09%. Weight loss history & BMI correlated with the degree of sarcopenia. Out of 66 patients 13% (n = 9) patients were unresectable. Moderate sarcopenia group had more statistically significant (P -0.02) unresectable disease compared to mild and non-sarcopenic groups. In postoperative period, sarcopenic group (64.51% vs 38.36 %) had more grade 2 complications though statistically insignificant. There was no difference in hospital stay between the two groups. In patients with GC , postoperative respiratory complication occurred in 11.53% (n = 3) of sarcopenic patients and 5.5%(n = 1) of non-sarcopenic patients, anastomotic leak occurred in 7.69% (n = 2) of sarcopenic patients and 5.5% (n = 1) of nonsarcopenic patients. Conclusions: The prevalence of sarcopenia is higher in patients with gastroesophageal cancer compared to lung cancer. The important factors that affect the sarcopenia include age and body mass index and weight loss history. The study has showed a trend towards increased post-operative complications and increased unresectable cases in patients with mild to moderate sarcopenia. Further larger studies are required to validate if sarcopenia can be used as an adjunct to predict resectability and post-operative outcomes.

Background: This study aimed to retrospectively investigate the efficacy and safety of recombinant human endostatin (Rh-endostatin) combined with radiotherapy in advanced non-small-cell lung cancer (NSCLC). Methods: Patients with unresectable stage III and IV NSCLC who treated with radiotherapy were enrolled. Patients who received Rh-endostatin infusion throughout the whole peri-radiotherapy period formed the Endostar group, and those who received no Rh-endostatin infusion were the control group. Results: The median progression-free survival was 8.0 and 4.4 months (hazard ratio: 0.53; 95% CI: 0.32–0.90; p = 0.019) and median overall survival was 40.0 and 13.1 months (hazard ratio: 0.53; 95% CI: 0.28–0.98; p = 0.045) for the Endostar and control groups, respectively. The Endostar group exhibited a numerically lower rate of radiation pneumonitis relapse, radiation pneumonitis death and pulmonary fibrosis. Conclusion: Rh-endostatin infusion throughout the peri-radiotherapy period enhanced radiosensitivity and showed better survival outcomes and a tendency toward fewer radiation-related pulmonary events in patients with NSCLC.

Occupationally-exposed lead affects the neuromuscular junction and might cause disturbances in the locomotor activity. This study was undertaken to evaluate pteridine metabolism, in which neurotransmitters are synthesized in battery workers. Urinary neopterin, biopterin and creatinine were measured using high performance liquid chromatography. Serum neopterin concentrations were detected by enzyme-linked immunoassay. Blood dihydropteridine reductase (DHPR) activities and delta-aminolevulinic acid (delta-ALA) were measured spectrophotometrically. Blood and urinary lead were detected by atomic absorption spectroscopy. Significantly increased blood and urinary lead levels, urinary neopterin, biopterin and delta-ALA were found in workers, while DHPR activities were indifferent compared to control group. Urinary creatinine decreased. This is the first study to demonstrate that increased activity of the pteridine pathway results in the accumulation of the neurotransmitters that may be responsible for the neurological disorders.

Abstract Background Cigarette smoking is a major risk factor for chronic obstructive pulmonary disease (COPD) and lung cancer. Epithelial–mesenchymal transition (EMT) is an essential pathophysiological process in COPD and plays an important role in airway remodeling, fibrosis, and malignant transformation of COPD. Previous studies have indicated FERMT3 is downregulated and plays a tumor-suppressive role in lung cancer. However, the role of FERMT3 in COPD, including EMT, has not yet been investigated. Methods The present study aimed to explore the potential role of FERMT3 in COPD and its underlying molecular mechanisms. Three GEO datasets were utilized to analyse FERMT3 gene expression profiles in COPD. We then established EMT animal models and cell models through cigarette smoke (CS) or cigarette smoke extract (CSE) exposure to detect the expression of FERMT3 and EMT markers. RT-PCR, western blot, immunohistochemical, cell migration, and cell cycle were employed to investigate the potential regulatory effect of FERMT3 in CSE-induced EMT. Results Based on Gene Expression Omnibus (GEO) data set analysis, FERMT3 expression in bronchoalveolar lavage fluid was lower in COPD smokers than in non-smokers or smokers. Moreover, FERMT3 expression was significantly down-regulated in lung tissues of COPD GOLD 4 patients compared with the control group. Cigarette smoke exposure reduced the FERMT3 expression and induces EMT both in vivo and in vitro. The results showed that overexpression of FERMT3 could inhibit EMT induced by CSE in A549 cells. Furthermore, the CSE-induced cell migration and cell cycle progression were reversed by FERMT3 overexpression. Mechanistically, our study showed that overexpression of FERMT3 inhibited CSE-induced EMT through the Wnt/β-catenin signaling. Conclusions In summary, these data suggest FERMT3 regulates cigarette smoke-induced epithelial–mesenchymal transition through Wnt/β-catenin signaling. These findings indicated that FERMT3 was correlated with the development of COPD and may serve as a potential target for both COPD and lung cancer.

Abstract Objective The aim of this study was to explore the safe and effective method of expectoration in the preoperative period of patients with lung cancer resection and to promote the rehabilitation of patients. Methods A total of 100 cases of lung cancer patients undergoing elective surgery were divided into the observation group and the control group, with 50 cases in each group. The control group was treated with vibration expectoration vest for expectoration during the perioperative period, and the observation group was treated with respiratory function exerciser that has expectoration function in the perioperative period, three times a day, and the effect was evaluated after 5 days. Results The number of patients in the observation group after the first expectoration time was significantly less than that of the control group (P<0.001). Pain score, pulmonary atelectasis, and pulmonary infection rate of the observation group were significantly lower than those of the control group; the hospitalization time was significantly shorter than that of the control group; and the difference was statistically significant (P<0.05). Conclusions Lobectomy for lung cancer patients with perioperative respiratory training for respiratory function exercise, compared with conventional methods, is helpful for postoperative expectoration and to reduce the incidence of adverse events.

Abstract BackgroundLow-dose computed tomographic (LDCT) screening has been proven to be powerful in detecting lung cancers in early stage. However, it’s hard to carry out in less-developed regions in lacking of facilities and professionals. The feasibility and efficacy of mobile LDCT scanning combined with remote reading by experienced radiologists from superior hospital for lung cancer screening in deprived areas was explored in this study.MethodsA prospective cohort was conducted in rural areas of western China. Residents over 40 years old were invited for lung cancer screening by mobile LDCT scanning combined with remote image reading or local hospital-based LDCT screening. Rates of positive pulmonary nodules and detected lung cancers in the baseline were compared between the two groups.ResultsAmong 8073 candidates with preliminary response, 7251 eligibilities were assigned to the mobile LDCT with remote reading (n = 4527) and local hospital-based LDCT screening (n = 2724) for lung cancer. Basic characteristics of the subjects were almost similar in the two cohorts except that the mean age of participants in mobile group was relatively older than control (61.18 vs. 59.84 years old, P < 0.001). 1778 participants with mobile LDCT scans with remote reading (39.3%) revealed 2570 pulmonary nodules or mass, and 352 subjects in the control group (13.0%) were detected 472 ones (P < 0.001). Proportions of nodules less than 8 mm or subsolid were both more frequent in the mobile LDCT group (83.3% vs. 76.1%, 32.9% vs. 29.8%, respectively; both P < 0.05). In the baseline screening, 26 cases of lung cancer were identified in the mobile LDCT scanning with remote reading cohort, with a lung cancer detection rate of 0.57% (26/4527), which was significantly higher than control (4/2724 = 0.15%, P = 0.006). Moreover, 80.8% (21/26) of lung cancer patients detected by mobile CT with remote reading were in stage I, remarkedly higher than that of 25.0% in control (1/4, P = 0.020).ConclusionMobile LDCT combined with remote reading is probably a potential mode for lung cancer screening in rural areas.Trial registrationNo. of registration trial was ChiCTR-DDD-15007586 (http://www.chictr.org).
