Abstract Background: Palliative radiotherapy (RT) represents an important treatment opportunity for improving the quality of life in metastatic non-small cell lung cancer (NSCLC) patients through the management of symptoms within the course of the illness. This study examines the patient and clinical factors associated with palliative RT use among metastatic NSCLC patients in Puerto Rico. Methods: A retrospective cohort study was performed using secondary data analysis from 2009-2015 from the Puerto Rico Central Cancer Registry–Health Insurance Linkage Database (PRCCR-HILD). A logistic regression model was used to examine factors associated with palliative RT. Results: Among the 929 patients identified with metastatic NSCLC, 33.80% received palliative RT within the first year after diagnosis. After adjusting for other covariates, receipt of chemotherapy (ORAdj = 3.90; 95% CI = 2.91-5.45; P < 0.001) and presence of symptoms (ORAdj =1.41; 95% CI =1.00-1.98; P = 0.045) were associated with increased odds of palliative RT use. Although marginally significant, patients with private health insurance had increased odds of palliative RT use (ORAdj = 1.50; 95% CI = 0.98-2.29; P = 0.061) when compared to beneficiaries of Medicaid, after adjusting by other covariates. Conclusions: The results of this study reveal concerning underuse of palliative RT among patients with metastatic NSCLC in Puerto Rico. Additional research is necessary to further understand the barriers to using palliative RT on the island.

Abstract Background Palliative radiotherapy (RT) represents an important treatment opportunity for improving the quality of life in metastatic non-small cell lung cancer (NSCLC) patients through the management of symptoms within the course of the illness. The aim of the study is to determine the proportion of patients who had palliative RT within 12 months of diagnosis and evaluate the factors associated with it. Methods A retrospective cohort study was performed using secondary data analysis from 2009 to 2015 from the Puerto Rico Central Cancer Registry–Health Insurance Linkage Database (PRCCR-HILD). A logistic regression model was used to examine factors associated with palliative RT. Results Among the 929 patients identified with metastatic NSCLC, 33.80% received palliative RT within the first year after diagnosis.

IntroductionPD-(L)1 inhibitors have improved prognosis of non-small-cell lung cancer (NSCLC), but can also cause immune-related adverse events (irAEs) that complicate management.MethodsWe analyzed NSCLC patients receiving PD-(L)1 inhibitors from 2012 to 2020 in a German academic center.ResultsIrAE showed comparable frequencies in stage IV (198/894 or 22%) vs. III (14/45 or 31%, p = 0.15), after anti-PD-(L)1 monotherapy vs. chemoimmunotherapy (139/483 vs. 58/213, p = 0.75), and across treatment lines. In stage IV, irAE occurred after 3.1 months in median, affected multiple organs (median 2) in 27/894 patients and were associated with PD-L1 positivity (25 vs. 14%, p = 0.003), lower neutrophil-to-lymphocyte ratios (29 vs. 17%, p &lt; 0.001 for NLR dichotomized at 5), better ECOG status (26 vs. 18% for 0 vs. 1, p = 0.004), but not related to age, sex, smoking and palliative radiotherapy. Two hundred thirty two irAEs occurred mostly in endocrine glands (4.9%), lungs (4.4%), the musculoskeletal system (4.2%), colon (4.1%), liver (3.7%), and skin (2.6%), while pneumonitis was most frequent with durvalumab following definitive chemoradiation (16% or 7/45, p &lt; 0.01). IrAE severity was grade 1 in 11%, 2 in 41%, 3 in 36%, and 4 in 11% events, while two were lethal (&lt;1%, myocarditis and pneumonitis). Therapy was suspended in 72%, while steroids were initiated in 66% and complemented by other immunosuppressants in 6%, with longest treatment duration for rheumatic events (mean &gt;3 months), and average cumulative prednisone doses &gt;700 mg for all organs, except for skin. Patients developing irAE had longer progression-free (PFS) and overall survival (OS) in multivariable 12/14-week landmark analyses including ECOG status, treatment line, treatment type, PD-L1 TPS, and NLR (median PFS 17 vs. 10 months, HR = 0.68, p = 0.009; median OS 37 vs. 15 months, HR = 0.40, p &lt; 0.001), regardless of grade. OS was longest with skin (95% at 2 years) and shortest with pneumonitis, hepatitis, neurologic, and cardiologic irAE (38, 37, 28, and 0% at 2 years, p &lt; 0.001).ConclusionsApproximately one-fourth of immunotherapy-treated NSCLC patients develop irAEs, most of which necessitate treatment suspension and steroids. Despite more frequent occurrence with PD-L1 positive tumors, lower NLR, and better ECOG PS, irAEs are independently associated with longer survival, especially when affecting the skin. Lethality is below 1%.

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.

6577 Background: Non small cell lung cancer (NSCLC) represents the number one cause of cancer mortality in the United States. Over several decades clinical research has focused on the development of new, more active chemotherapeutic drugs to improve survival. Over the time period from 1994 to 2003 six drugs have been approved for the treatment of metastatic NSCLC. We are presenting a population based analysis of the survival in patients with metastatic NSCLC in the US from 1981–1990, 1991–1997 and 1998–2003. We also provide a pharmaco-economic view of this observation. Methods: We analyzed the SEER (Surveillance, Epidemiology, and End Results) program database for cancer specific survival rates in stage IV NSCLC patients who were diagnosed between 1980 and 2003 in the SEER catchment geographic areas. The primary exposure of interest was the year of diagnosis. Results: We identified 52,086 eligible patients in total. 8,950, 21,111 and 18,712 patients were diagnosed 1981 to1990, 1991 to 1997 and 1998 to 2003 respectively. The cox proportional hazard ratios were 0.97 (95% CI 0.94–0.99) and 0.85 (0.83–0.88) for the time periods 1991 to 1997 and 1998 to 2003, respectively, using the time period from 1981 to1990 as reference. This subtle increase in survival was strictly paralleled by increasing costs for the medical care of this patient population. Conclusions: The survival of stage IV NSCLC patients seems to be mildly improving, what is paralleled by increasing cost for the care of those patients.

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.

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]

AbstractBackgroundExosomal microRNAs (miRNAs) are proposed to be excellent candidate biomarkers for clinical applications. However, little is known about their potential value as diagnostic biomarkers for metastatic non-small cell lung cancer (NSCLC).MethodsIn this study, microarrays were used to determine distinct miRNA profiles of plasma exosomes in a discovery cohort of healthy donors, metastatic NSCLC and nonmetastatic NSCLC patients. Three potential candidate miRNAs were selected based on the differential expression profiles. The discovery set data were validated by quantitative real-time polymerase chain reaction using a validation cohort.ResultsNSCLC patients (n = 80) and healthy controls (n = 30) had different exosome-related miRNA profiles in plasma. Results demonstrated that the level of let-7f-5p was decreased in plasma exosomes of NSCLC patients (p < 0.0001). Further analysis of three differentially expressed miRNAs revealed that miR-320a, miR-622 and let-7f-5p levels could significantly segregate patients with metastatic NSCLC from patients with nonmetastatic NSCLC (p < 0.0001, p < 0.0001 and p = 0.023, respectively). In addition, the combination of let-7f-5p, CEA and Cyfra21-1 generated an area under the curve (AUC) of 0.981 for the diagnosis of NSCLC patients, and the combination of miR-320a, miR-622, CEA and Cyfra21-1 had an AUC of 0.900 for the diagnosis of patients with metastatic NSCLC.ConclusionsThis novel study demonstrated that plasma exosomal miRNAs are promising noninvasive diagnostic biomarkers for metastatic NSCLC.

<b><i>Introduction:</i></b> The length of the necessary waiting period to test driver mutations may generate anxiety in patients and clinicians. For this reason, an investigation was conducted to determine whether the duration between diagnosis and the start of first-line chemotherapy (DDC) in non-small cell lung cancer (NSCLC) patients without driver mutations has an impact on prognosis. <b><i>Methods:</i></b> The study included 303 de novo metastatic NSCLC patients without a driver mutation and patients were divided into 2 groups according to DDC: ≤30 days (group A) or &#x3e;30 days (group B). The determinant factors for progression-free survival (PFS) and overall survival (OS) were examined by Cox regression analysis. <b><i>Results:</i></b> The mean DDC was calculated as 38.2 ± 54.5 days. The number of patients in group A and B were 183 and 120, respectively. The median PFS in groups A and B was 5.0 and 6.0 months (<i>p</i> = 0.268) and the median OS was 10.0 and 11 months, respectively (<i>p</i> = 0.341). Univariate and multivariate analyses revealed that DDC was not a factor associated with PFS and OS. <b><i>Conclusion:</i></b> Our results show that a higher DDC was not associated with a worse prognosis in metastatic NSCLC patients without driver mutations. In this context, it is safer for patients and their physicians to wait for test results before starting chemotherapy.
