BackgroundAnlotinib is a multi-targeted tyrosine kinase inhibitor mainly targeting angiogenesis signaling. The predictive marker of anlotinib’s efficacy remains elusive. This study was designed to explore the predictive marker of anlotinib in non-small cell lung cancer (NSCLC).MethodsWe prospectively enrolled 52 advanced NSCLC patients who underwent at least one line of targeted therapy or chemotherapy between August 2018 and March 2020. Patients were divided into durable responders (DR) and non-durable responders (NDR) based on the median progression-free survival (PFS, 176 days). The Olink Immuno-Oncology panel (92 proteins) was used to explore the predictive protein biomarkers in plasma samples before treatment (baseline) and on the first treatment evaluation (paired).ResultsAt baseline, the response to anlotinib was not significantly associated with age, gender, smoke history, histology, oligo-metastases, EGFR mutations, and other clinical characteristics. The results of PFS-related protein biomarkers at baseline were all not satisfying. Then we assessed the changes of 92 proteins levels in plasma on the first treatment evaluation. We obtained a Linear discriminant analysis (LDA) model based on 7 proteins, with an accuracy of 100% in the original data and an accuracy of 89.2% in cross validation. The 7 proteins were CD70, MIC-A/B, LAG3, CAIX, PDCD1, MMP12, and PD-L2. Multivariate Cox analysis further showed that the changes of CD70 (HR 25.48; 95% CI, 4.90–132.41, P=0.000) and MIC-A/B (HR 15.04; 95% CI, 3.81–59.36, P=0.000) in plasma were the most significant prognostic factors for PFS.ConclusionWe reported herein a LDA model based on the changes of 7 proteins levels in plasma before and after treatment, which could predict anlotinib responders among advanced NSCLC patients with an accuracy of 100%. Further studies are warranted to verify the prediction performance of the LDA model.

Abstract Introduction Immune checkpoint inhibitors (ICIs) have become a frontier in the field of clinical technology for advanced non-small cell lung cancer (NSCLC). Currently, the predictive biomarker of ICIs mainly including the expression of PD-L1, TMB, TIICs, MMR and MSI-H. However, there are no official biomarkers to guide the treatment of ICIs and to determine the prognosis. Therefore, it is essential to explore a systematic nomogram to predict the prognosis of ICIs treatment in NSCLC Methods In this work, we obtained gene expression and clinical data of NSCLC patients from the TCGA database. Immune-related genes (IRGs) were downloaded from the ImmPort database. The detailed clinical annotation and response data of 240 advanced NSCLC patients who received ICIs treatment were obtained from the cBioPortal for Cancer Genomics. Kaplan–Meier survival analysis was used to perform survival analyses, and selected clinical variables to develop a novel nomogram. The prognostic significance of FGFR4 was validated by another cohort in cBioPortal for Cancer Genomics. Results 3% of the NSCLC patients harbored FGFR4 mutations. The mutation of FGFR4 were confirmed to be associated with PD-L1, and TMB. Patients harbored FGFR4 mutations were found to have a better prolonged progression-free survival (PFS) to ICIs treatment (FGFR4: P = 0.0209). Here, we built and verified a novel nomogram to predict the prognosis of ICIs treatment for NSCLC patients. Conclusion Our results showed that FGFR4 could serve as novel biomarkers to predict the prognosis of ICIs treatment of advanced NSCLC. Our systematic prognostic nomogram showed a great potential to predict the prognosis of ICIs for advanced NSCLC patients.

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.

Abstract Background: Single agent maintenance therapy has been approved for the treatment of advanced non-small-cell lung cancer (NSCLC) due to its potential survival benefits, but whether combined maintenance therapy would improve the survival of advanced NSCLC remains undetermined. Methods: Relevant trials were identified by searching electronic databases and conference meetings. Prospective randomized controlled trials (RCTs) assessing combination maintenance therapy in advanced NSCLC patients were included. Outcomes of interest included overall survival (OS), progression-free survival (PFS), and grade 3–4 toxicities. Results: A total of 1950 advanced NSCLC patients received combination maintenance treatment from six trials were included for analysis. The use of doublet maintenance therapy in NSCLC patients significantly improved PFS (HR 0.74, 95%CI: 0.59–0.93, P = 0.010), but not for OS (HR 0.95, 95%CI: 0.85–1.07, P = 0.40) in comparison with single agent maintenance therapy. Similar results were observed in sub-group analysis according to treatment regimens. In addition, there was no significantly risk difference between doublet and single agent maintenance therapy in terms of grade 3/4 hematologic and non-hematologic toxicities. Conclusion: The findings of the present study show that doublet combination maintenance therapy is superior to single agent maintenance therapy in terms of PFS, without increased grade 3–4 toxicities. Future prospective studies are recommended to clearly assess the long-term clinical benefit of doublet maintenance therapy and its impact on health-related quality of life.

Abstract Background Noninvasive prognostic biomarkers are needed for advanced non-small cell lung cancer (NSCLC) patients with different histological types to identify cases with poor survival. Here, we investigated the prognostic values of peripheral CD8+CD28+ T cells and CD8+CD28− T cells in advanced NSCLC patients treated with chemo(radio)therapy and the impact of histological type on them. Methods Of 232 registered advanced NSCLC patients, 101 treatment-naïve individuals were eligible and included in our study. Flow cytometry was used to evaluate CD8+CD28+ T cells, CD8+CD28− T cells, CD4+ CD25hi T cells, B cells, natural killer cells, γδT cells, and natural killer T cells in patients’ peripheral blood. Results The median follow-up time was 13.6 months. Fifty-nine (58.4%) patients died by the end of our study. Fifty-three of the 101 advanced NSCLC cases selected for our study were adenocarcinomas (ADs), and 48 were squamous cell carcinomas (SCCs). Multivariate analyses showed that increased levels of CD8+CD28+ T cells independently predicted favorable overall survival (OS) [hazard ratio (HR): 0.51, 95% confidence interval (CI) 0.30–0.89, P = 0.021] and progression-free survival (PFS) (HR: 0.66, 95% CI 0.37–0.93, P = 0.038) in ADs, but the prediction in SCCs was not statistically significant. In contrast, high levels of CD8+CD28− T cells independently predicted unfavorable OS (HR: 1.41, 95% CI 1.17–3.06, P = 0.035) and PFS (HR: 2.01, 95% CI 1.06–3.85, P = 0.029) in SCCs, but the prediction in ADs was not statistically significant. ADs had higher levels of CD4+CD25hi T cells and CD8+CD28− T cells and lower NK cells (all P < 0.05) than SCCs. Conclusions Our findings uncovered the prognostic values of peripheral CD8+CD28+ T cells and CD8+CD28− T cells in advanced NSCLC patients treated with chemo(radio)therapy, which could help to identify patients with poor outcomes and refine treatment strategies.

Background: In the recent years, immunotherapeutics and specifically immunecheckpoints inhibitors have marked a significant shift in the diagnostic and therapeutic algorithm of Non-Small Cell Lung Cancer (NSCLC), allowing us to use immunotherapeutics alone or combined with chemotherapy for a great subset of patients. However, new interesting approaches are being presently investigated, markedly immunotherapy combinations, that is, the use of two or more immunotherapeutics combined. Methods: In particular, the combination of anti-PD-1 nivolumab and anti-CTLA-4 ipilimumab has already provided groundbreaking positive results in the advanced NSCLC and other combinations are currently under investigation. Results: Therefore, this paper aims to provide a comprehensive state-of-the-art review about immunotherapy combination, along with suggestions about future directions. A comprehensive literature search was carried out to identify eligible studies from MEDLINE/PubMed and ClinicalTrials.gov. Conclusion: Nivolumab plus ipilimumab represent the most promising immunotherapy combination for the treatment of advanced NSCLC patients; safety, tolerability and efficacy of new immunotherapeutics (in monotherapy and in immunotherapy combinations) must be further assessed in future studies.

Lung cancer (LC) is the main cause of death for cancer worldwide and non-small cell lung cancer (NSCLC) represents the most common histology. The discovery of genomic alterations in driver genes that offer the possibility of therapeutic intervention has completely changed the approach to the diagnosis and therapy of advanced NSCLC patients, and tumor molecular profiling has become mandatory for the choice of the most appropriate therapeutic strategy. However, in approximately 30% of NSCLC patients tumor tissue is inadequate for biomarker analysis. The development of highly sensitive next generation sequencing (NGS) technologies for the analysis of circulating cell-free DNA (cfDNA) is emerging as a valuable alternative to assess tumor molecular landscape in case of tissue unavailability. Additionally, cfDNA NGS testing can better recapitulate NSCLC heterogeneity as compared with tissue testing. In this review we describe the main advantages and limits of using NGS-based cfDNA analysis to guide the therapeutic decision-making process in advanced NSCLC patients, to monitor the response to therapy and to identify mechanisms of resistance early. Therefore, we provide evidence that the implementation of cfDNA NGS testing in clinical research and in the clinical practice can significantly improve precision medicine approaches in patients with advanced NSCLC.

71 Background: The main objectives of this study were to characterize and compare the burden of non-small cell lung cancer (NSCLC) patients who reported considerable weight loss ( ≥ 5% of their body weight in the past 6 months or ≥ 2% for a BMI less than 20 kg/m2) to those who did not. Methods: 95 advanced NSCLC patients were surveyed from the online patient-powered community PatientsLikeMe. Self-reported demographic and clinical characteristics were recorded. Appetite, distress and concerns, health-related quality of life (QLQ-C15-PAL) and anorexia-cachexia symptoms/concerns (FAACT A/CS) were summarized. The results obtained between patients who lost considerable weight and those who did not were compared, using a two-tailed t-test or a Kruskal-Wallis test. Patients with weight loss were additionally asked open-ended questions on burden and concerns. Results: 35 (37%) patients were classified as having considerable weight loss at the time of the survey and 60 (63%) where classified without. Most patients were female (81%), American (81%), and mean age was 59 years. 61% of patients indicated not receiving either chemotherapy or radiotherapy at the time of the survey. Patients with weight loss reported significantly (p < 0.05) lower overall quality of life (55.2 vs. 66.9), worsened anorexia-cachexia symptoms/concerns (30.7 vs. 36.0), and higher symptomology, specifically fatigue (64.8 vs. 49.1), nausea (19.5 vs. 9.2), and appetite loss (41.0 vs. 23.9) – than patients without weight loss. In addition, significantly more patients who lost weight reported moderate/high distress levels than patients who did not (71% vs. 38%). For patients with weight loss, change in food taste, fatigue, and decrease in appetite were the most frequently reported symptoms with the greatest impact on their lives. Conclusions: Our results support that weight loss negatively affects cancer patients’ quality of life and is associated with more distress and symptoms—particularly fatigue, and appetite loss. Weight loss-related symptoms also significantly impact their lives. Interventions targeted at maintaining/increasing body weight may help to improve well-being and reduce key symptoms in advanced NSCLC patients with considerable weight loss.

e20666 Background: Currently regimen for advanced non-small cell lung cancer (NSCLC) failing from standard treatment is deficient. This retrospective study aimed to assess the efficacy and safety of low-dose apatinib in combination with S-1 therapy in this NSCLC setting. Methods: In this retrospective study, advanced NSCLC patients who failed from standard treatment in Changzhou Cancer Hospital of Soochow University were screened for eligibility. Progression-free survival (PFS) was set as the primary endpoint. Overall response rate (ORR), disease control rate (DCR), Overall survival (OS) and safety profile were considered to be the secondary endpoints. Results: 31 eligible patients were included in this study. The median PFS (mPFS) was 102 days (95% CI: 57-147). 7 patients (23%; 95% CI: 11-38%) achieved an objective response and the DCR was maintained in 23 patients (75%; 95% CI: 58-86%). The median OS (mOS) was 422 days (95% CI: 148-696).Patients with smoking had a tendency for shorter overall survival without significant differences (HR = 4.105, 95% CI: 0.874-19.288, P = 0.074). Treatment-related grade 3 toxicity was observed in five patients (16%) and the common grade 1 or 2 adverse events were fatigue (42%), hypertension (32%), and hand-foot-skin reaction (23%). Conclusions: Combination of low-dose apatinib and S-1 could be effective and tolerable for advanced NSCLC patients failed from standard treatment, but further exploration in larger clinical trials is needed.

Igf1r Expression

Abstract Background The insulin-like growth factor 1 receptor (IGF1R) expression has been addressed as a potential prognostic marker in non-small-cell lung cancer (NSCLC) in various studies; however, the associations between IGF1R expression and prognosis of advanced NSCLC patients is still controversial. The aim of our observational, cohort study was to evaluate the expression of IGF1R in advanced NSCLC and its prognostic role. A subgroup analysis was performed to address the influence of pre-existing type 2 diabetes mellitus (T2DM) status on IGF1R expression and overall survival (OS). Patients and methods IGF1R expression was evaluated in 167 consecutive advanced NSCLC patients (stage IIIB and IV), diagnosed and treated at one university institution, between 2005 and 2010. All patients received at least one line of standard cytotoxic therapy and 18 of them had pre-existing T2DM. IGF1R expression was determined by immunohistochemical (IHC) staining, with score ≥ 1+ considered as positive. Information on baseline characteristics, as well as patients’ follow-up data, were obtained from the hospital registry. Associations of IGF1R expression with clinical characteristics and overall survival were compared. Results IGF1R expression was positive in 79.6% of patients, significantly more often in squamous-cell carcinoma (SCC) compared to non-squamous-cell (NSCC) histology (88.7% vs. 74.3%; P = 0.03). IGF1R positivity did not correlate with T2DM status or with other clinical features (sex, smoking status, performance status). Median OS was similar between IGF1R positive and IGF1R negative group (10.2 vs. 8.5 months, P = 0.168) and between patients with or without T2DM (8.7 vs. 9.8 months, P = 0.575). Neither IGF1R expression nor T2DM were significant predictors of OS. Conclusions IGF1R or T2DM status were not significantly prognostic in described above collective of advanced NSCLC treated with at least one line of chemotherapy. In addition, no association between T2DM status and IGF1R expression was found. Further studies on IGF1R expression and its prognostic as well as therapeutic consequences in a larger collective of advanced NSCLC patients, with or without T2DM, are needed.
