9025 Background: Many patients diagnosed with advanced non-small cell lung cancer (NSCLC) will develop intracranial metastasis, contributing significantly to morbidity and mortality. Immunotherapy (IMT) has emerged as the standard of care in select cases of metastatic NSCLC, though data investigating the survival impact of IMT and radiation (XRT) in these patients is limited. To characterize the survival impact of intracranial XRT and IMT in NSCLC patients with brain metastasis, we analyzed the National Cancer Database (NCDB). Methods: We queried the NCDB for patients with metastatic NSCLC having brain metastasis receiving intracranial XRT ± IMT. Univariable and multivariable analyses identified characteristics predictive of overall survival. Cox proportional hazard ratios with propensity matching mitigated indication bias between the two arms. Results: 13,998 NSCLC patients who received IMT (n = 545) or did not receive IMT (n = 13,545) were eligible for analysis. Univariable analysis demonstrated a median overall survival of 13.1 months (95% CI: 11.8-15.0) vs. 9.7 months (95% CI: 9.5-9.9) (p < 0.0001) and 3-year overall survival of 17% vs. 12% [p < 0.0001; HR: 0.77 (0.71-0.84)] in patients receiving and not receiving IMT respectively. Patients with N3 disease and those diagnosed between 2012 and 2014 were more likely to have received IMT. Receipt of IMT remained an independent predictor of increased survival on propensity score matched multivariable comparison (p = 0.0002). Conclusions: Receipt of IMT was an independent predictor of increased overall survival in patients with NSCLC having intracranial metastasis. Randomized, prospective studies are needed to further validate these findings. [Table: see text]

AimsCombination of anti-angiogenesis therapy and immunotherapy has showed synergistic effects in non-small cell lung cancer (NSCLC). The aim of this retrospective study was to investigate the efficacy and safety of anlotinib with and without immunotherapy in NSCLC.MethodsPathologically confirmed NSCLC patients (stage IIIB-IV) receiving anlotinib between November 2018 and February 2020 were enrolled for retrospective analysis. The outcomes and safety of overall patients were evaluated, and the efficacies of anlotinib plus immunotherapy and anlotinib alone was compared. The primary endpoint was progression-free survival (PFS).ResultsA total of 80 patients (median age: 62 years, range: 29-86 years) were included. Overall median PFS was 4.3 months (95% confidence interval (CI): 2.7-5.9 months). In univariate analysis, patients without EGFR mutation, previous EGFR target therapy, and brain metastasis had significantly longer PFS. Cox regression analysis showed that only brain metastasis was an independent predictor of PFS. The median PFS of patients receiving anlotinib plus immunotherapy was slightly longer than that of patients receiving anlotinib alone (4.2 vs 3.1 months); however, the difference was not statistically significant. A tendency of longer median PFS was observed in patients with adenocarcinoma, EGFR wild type, stage IV, no liver metastasis, former smoker, ≥2 previous treatment lines, no previous VEGF or EGFR target therapies in anlotinib plus immunotherapy group. Treatments with anlotinib alone or anlotinib plus immunotherapy were well tolerable. The most common adverse events were fatigue, decreased hemoglobin count, hypertension, hand-foot syndrome, oral mucositis and hoarseness.ConclusionAnlotinib is well tolerable and effective in advanced NSCLC patients. Brain metastasis is an independent predictor of PFS in NSCLC patients receiving anlotinib. Future prospective studies with larger sample size and extended follow-up are needed to confirm the clinical benefit in NSCLC patients treated with anlotinib combined with immunotherapy.

7671 Background: Brain metastases confer significant morbidity and a poorer survival in non-small cell lung cancer (NSCLC). Vascular endothelial growth factor-targeted antiangiogenic therapies (AAT) have demonstrated benefit for patients with metastatic NSCLC and are expected to directly inhibit the pathophysiology and morbidity of brain metastases, yet patients with brain metastases have been excluded from most clinical trials of AAT for fear of intracranial hemorrhage (ICH). This is a low suspected risk, but needs to be quantitated to plan clinical trials of AAT for NSCLC brain metastases. Methods: Data from MD Anderson Cancer Center Tumor Registry and electronic medical records from January 1998 to March 2006 was interrogated. 2143 patients with metastatic NSCLC registering from Jan 1998 to Sept 2005 were followed till March 2006. 776 patients with and 1367 patients without brain metastases were followed till death, date of ICH, or last date of study, whichever occurred first. Results: The incidence of ICH seemed to be higher in those with brain metastasis compared to those without. However, the rates of symptomatic ICH were not significantly different. All ICH patients with brain metastasis had received radiation therapy for them and were not anticoagulated. Most of the brain metastasis-associated ICH's were asymptomatic, detected during radiologic surveillance. The rates of symptomatic ICH, or cerebrovascular accidents were similar and not significantly different between the two groups. The following table depicts the rates of CVA and/or ICH in metastatic NSCLC patients. Conclusions: In metastatic NSCLC patients, the incidence of spontaneous ICH appeared to be higher in those with brain metastases compared to those without, but was very low in both groups nonetheless without a statistically significant difference. These data suggest minimal risk of clinically significant ICH for NSCLC brain metastasis patients and justifies for them clinical trials of AAT. No significant financial relationships to disclose.

Introduction Survival after a diagnosis of brain metastasis in non-small-cell lung cancer (nsclc) is generally poor. We previously reported a median survival of approximately 4 months in a cohort of patients treated with whole-brain radiotherapy (wbrt). Since that time, we implemented a program of stereotactic radiosurgery (srs). In the present study, we examined survival and prognostic factors in a consecutive cohort of patients after the introduction of the srs program.Methods Data from a retrospective review of 167 nsclc patients with brain metastasis referred to a tertiary cancer centre during 2010–2012 were compared with data from a prior cohort of 91 patients treated during 2005–2007(“pre-srs cohort”).Results Median overall survival from the date of diagnosis of brain metastasis (4.3 months in the srs cohort vs. 3.9 months in the pre-srs cohort, p = 0.74) was not significantly different in the cohorts. The result was similar when the no-treatment group was excluded from the srs cohort. Within the srs cohort only, significant differences is overall survival were observed between treatment groups (srs, wbrt plus srs, wbrt, and no treatment), with improved survival being observed on univariate and multivariate analysis for patients receiving srs compared with patients receiving wbrt alone (p < 0.001).Conclusions No improvement in survival was observed for nsclc patients with brain metastases after the implementation of srs. Selected patients (younger age, female sex, good performance status, fewer brain metastases) treated with srs appeared to demonstrate improved survival. However, those observations might also reflect better patient selection for srs or a greater tendency to offer those patients systemic therapy in addition to srs.

Background: Immunotherapy combined with platinum-based chemotherapy is now the standard first-line treatment for non-small cell lung cancer (NSCLC) patients. However, limited evidence exists to show the efficacy of immunotherapy plus taxanes for patients who have progressed after platinum-based chemotherapy. Methods: The immunotherapy naïve patients with metastatic NSCLC who received anti-PD-1/PD-L1 monotherapy or combined with nab-paclitaxel after prior platinum-based chemotherapy from 2015 to 2018 in PLA General Hospital were identified. The progression-free survival, overall survival (OS), objective response rate (ORR), disease control rate (DCR) and safety were assessed. Results: Of 57 patients, 40 were treated with anti-PD-1/PD-L1 monotherapy and 17 were treated with anti-PD-1/PD-L1 plus nab-paclitaxel. With a median OS follow-up of 16.3 months, the nab-paclitaxel group showed significantly longer OS compared with the immune monotherapy group (median, 28.6 months versus 15.9 months, log-rank p = 0.020). When adjusted by covariates in COX proportional regression model, both the treatment group [ p = 0.009, hazard ratio (HR) 0.361; 95% confidence interval (CI) 0.168–0.773] and performance status ( p = 0.003, HR 0.372; 95% CI 0.192–0.721) demonstrated independent association with the longer OS from combination therapy. In addition, ORR was 23.5% (4/17) in the immune checkpoints inhibitors (ICIs) plus nab-paclitaxel group versus 13.5% (5/37) in immune monotherapy group ( p = 0.439), with a DCR of 88.2% (15/17) and 59.5% (22/37) ( p = 0.034), respectively. The incidence of grade 3/4 adverse events was 23.5% (4/17) in the combination group and 2.5% (1/40) in the immune monotherapy group. Conclusion: PD-1/PD-L1 inhibitor plus nab-paclitaxel resulted in significantly longer OS and higher response versus ICI single agent in metastatic NSCLC patients who have progressed after platinum-based chemotherapy. These findings need to be further explored by prospective studies.

Background. The aim was to investigate the potential factors related with overall survival of oligometastatic non-small-cell lung cancer (NSCLC) patients. Methods. A literature search was conducted in databases including PubMed, Embase, and Cochrane library up to March 2017. The hazard radio (HR) as well as the corresponding 95% confidence interval (CI) were calculated, and all the statistics analysis was performed by the R 3.12. Heterogeneity was analyzed using I-squared and Cochran Q tests. Furthermore, sensitivity analysis was performed to evaluate the stability of results. Results. In total, 6 articles were included in the meta-analysis. Nodal status was significantly correlated with the overall survival rate of NSCLC oligometastatic patients (HR: 1.69, 95% CI: 1.23–2.32, Z=3.20, P=0.001). No significant relationship was found between overall survival rate of NSCLC oligometastatic patients and the indicators including sex, stage, smoker, age, and histology. Notably, sensitivity analysis on data evaluating relationship between patients survival and the stage and histology showed that results were reversed after removing one of the studies. Conclusions. Nodal status might be associated with the overall survival of oligometastatic NSCLC patients.

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.
