The lung immune prognostic index (LIPI) has been shown to be an important prognostic marker for various tumors. However, the prognostic value of LIPI among non-small cell lung cancer (NSCLC) patients treated with systemic therapy remains controversial. We aimed to evaluate survival status according to LIPI among NSCLC patients receiving different forms of systemic therapy at our institution. We also performed a meta-analysis of articles from PubMed and Embase to illustrate this question. For our cohort, we found that good LIPI was associated with better overall survival (OS) among 91 patients on immunotherapy, 329 patients on targeted therapy, and 570 patients on chemotherapy. For the meta-analysis, a total of eight studies with 8,721 patients were included. Pooled results showed that a higher LIPI (those with 1 or 2 factors) was associated with poor overall progression-free survival (PFS) (hazard ratio [HR], 1.57; 95% confidence interval [CI], 1.45−1.71) and OS (HR, 2.01; 95% CI, 1.75−2.31). Subgroup analyses showed that a higher LIPI was related to poor survival among patients prescribed different systemic therapies: immunotherapy (OS HR, 2.50; 95% CI, 1.99–3.13; PFS HR, 1.77; 95% CI, 1.56–2.01), chemotherapy (OS HR, 1.58; 95% CI, 1.34–1.86; PFS HR, 1.38; 95% CI, 1.23–1.55), and targeted therapy (OS HR; 2.15, 95% CI, 1.57–2.96; PFS HR, 1.60; 95% CI, 1.25–2.06). The study shows that the LIPI is a clinically significant prognostic factor for NSCLC patients receiving systemic therapy.Systematic Review Registrationhttps://www.crd.york.ac.uk/PROSPERO/, identifier CRD420209009.

Abstract Objective Whether segmentectomy can be used to treat radiologically determined pure solid or solid-dominant lung cancer remains controversial owing to the invasive pathologic characteristics of these tumors despite their small size. This meta-analysis compared the oncologic outcomes after lobectomy and segmentectomy regarding relapse-free survival (RFS) and overall survival (OS) in patients with radiologically determined pure solid or solid-dominant clinical stage IA non-small cell lung cancer (NSCLC). Methods A literature search was performed in the MEDLINE, EMBASE, and Cochrane Central databases for information from the date of database inception to March 2019. Studies were selected according to predefined eligibility criteria. The hazard ratio (HR) and associated 95% confidence interval (CI) were extracted or calculated as the outcome measure for data combining. Results Seven eligible studies published between 2014 and 2018 enrolling 1428 patients were included in the current meta-analysis. Compared with lobectomy, segmentectomy had a significant benefit on the RFS of radiologically determined pure solid or solid-dominant clinical stage IA NSCLC patients (combined HR: 1.46; 95% CI, 1.05–2.03; P = 0.024) and there were no significant differences on the OS of these patients (HR: 1.52; 95% CI, 0.95–2.43; P = 0.08). Conclusions Segmentectomy leads to lower survival than lobectomy for clinical stage IA NSCLC patients with radiologically determined pure solid or solid-dominant tumors. Moreover, applying lobectomy to clinical stage IA NSCLC patients with radiologically determined pure solid or solid-dominant tumors (≤2 cm) could lead to an even bigger survival advantage. However, there are some limitations in the present study, and more evidence is needed to support the conclusion.

Nuclear factor kappa B (NF-κB), a key nuclear transcription factor, is associated with prognosis in a variety of human cancers. However, the clinical value of NF-κB in non-small cell lung cancer (NSCLC) is still controversial. Therefore, the aim of this meta-analysis was to obtain an accurate evaluation of the relationship between NF-κB expression and survival prognosis of NSCLC patients based on published articles. PubMed, EMBASE and Web of Science databases were systematically searched for potential articles. A total of 1159 patients from 7 eligible studies comparing prognostic significance of NF-κB expression levels in NSCLC were included in our meta-analysis. I2 statistic and P value were performed to evaluate heterogeneity using Review Manager version 5.3. The results of analysis were presented as hazard ratio (HR) or odds ratios with 95% confidence interval (95% CI). Subgroup analysis based on ethnicity of NSCLC patients was conducted to illustrate the potential discrepancy. Significant heterogeneity was considered at I2 > 50% and P < 0.05, and random-effects model was used. The combined results indicated that higher NF-κB expression was associated with shorter overall survival of NSCLC patients (HR = 2.78, 95% CI = 1.51–5.12, P = 0.001). Moreover, NF-κB expression was closely associated with tumor stage (HR = 0.32, 95% CI = 0.18–0.57, P < 0.0001) and lymph node metastasis (HR = 0.56, 95% CI = 0.38–0.83, P = 0.004). We conclude that NF-κB expression may be a potential unfavorable prognostic marker for NSCLC patients.

IntroductionOnly approximately 25% of stage iv non-small-cell lung cancer (nsclc) patients receive systemic therapy. For such patients, we examined factors affecting referral to a cancer centre (cc) and to medical oncology (mo), and use of systemic therapy.Methods Using the Glans–Look Lung Cancer database, we completed a chart review of stage iv nsclc patients diagnosed in Southern Alberta during 2003–2006 and 2010–2011, comparing median overall survival (mos), referral, and treatment in the two cohorts.Results Of the 922 patients diagnosed in 2003–2006 and the 560 diagnosed in 2010–2011, 94% and 82% respectively were referred to a cc, with 22% and 23% receiving traditional chemotherapy (tctx). Referral to a cc or mo and use of tctx correlated with survival (p < 0.0001): The mos duration was 11.2 months in those receiving tctx and 1.0 months in those not referred to a cc. The overall mos duration was similar in the two cohorts (4.1 months vs. 3.9 months, p = 0.47). Major reasons for lack of referral to mo included poor functional status, rapid decline, and patient wish, which were similar to the reasons for forgoing tctx. In the two cohorts, 87 (9.4%) and 42 (7.5%) patients received epidermal growth factor inhibitors, with a mos duration of 16.2 months. Multivariable analysis showed that male sex [hazard ratio (hr): 1.16; p = 0.008] and pulmonary embolus (hr: 1.2; p = 0.002) correlated with worse survival. In contrast, receipt of chemotherapy (hr: 0.5; p < 0.001) and enrolment in a clinical trial (hr: 0.76; p = 0.049) correlated with better survival.Conclusions Our experience confirms that, over time, uptake of systemic therapy, including tctx and targeted therapy, changed little despite their established efficacy. Most of the factors limiting systemic therapy uptake appear to be non-modifiable at the time of referral. Rapid diagnosis and the availability of well-tolerated drugs for all nsclc patients will likely be the most important factors in increasing systemic therapy uptake in this population.

The Impact

Abstract Background: Patients with non-small cell lung cancer (NSCLC) have a significantly higher risk of developing venous thromboembolism (VTE), a condition that significantly influences the prognosis of these patients. However, the impact of VTE on the survival of NSCLC patients remains unclear. We aim to evaluate the impact of VTE on the mortality of patients with NSCLC. Methods: We systematically reviewed all indexed studies examining the prognosis of NSCLC patients with VTE. Web of Science, EMBASE, PubMed, and the Cochrane Library were searched through December 31, 2019 to identify relevant studies. Fixed- or random-effects models were chosen based on heterogeneity. Results: Twelve articles with 6480 patients were included in this analysis. The heterogeneity of these studies was significant (I2=81%, P<0.01). The overall survival (OS) of NSCLC patients with VTE was shorter compared to patients without VTE (HR=1.71, 95% CI [1.39–2.10], P<0.01). Two small groups of SCLC patients were excluded and the remaining patients were divided into the Asian and non-Asian groups. The Asian group showed low heterogeneity (I2=35%, P=0.20), in which NSCLC patients with VTE also had shorter OS (HR=1.49, 95% CI [1.19–1.88], P<0.01). Conclusions: VTE is significantly associated with a shorter OS of NSCLC patients, especially in Asian patients. Proper prevention and management of VTE is the key to improving the survival of patients with NSCLC.

IntroductionPrevious studies have demonstrated that programmed cell death-ligand 1 (PD-L1) serves as biomarker for poor prognosis and survival in advanced-stage non-small cell lung cancer (NSCLC) patients. However, the merit of PD-L1 expression to predict the prognosis of early stage NSCLC patients who underwent complete resection remains controversial. In the present study, we performed a meta-analysis to investigate the relationship between PD-L1 expression and prognosis in patients with early stage resected NSCLC.MethodsElectronic databases, including PubMed, EMBASE, and the Cochrane Library, were searched until July 23 2020 for studies evaluating the expression of PD-L1 and the prognosis of resected NSCLCs. Hazard ratios (HRs) with 95% confidence intervals (CIs) of overall survival (OS) and disease-free survival (DFS) were pooled and analyzed. Heterogeneity and publication bias analyses were also assessed.ResultsA total of 15 studies involving 3,790 patients were considered in the present meta-analysis. The pooled HR indicated that PD-L1 expression related to a much shorter DFS (HR = 1.56, 95% CI: 1.18–2.05, p &lt; 0.01), as well a significantly worse OS (HR = 1.68, 95% CI: 1.29–2.18, p &lt; 0.01). Furthermore, our analysis indicated that PD-L1 expression was significantly associated with gender (male vs. female: OR = 1.27, 95% CI:1.01–1.59, p = 0.038), histology (ADC vs. SCC: OR = 0.54, 95% CI:0.38–0.77, p = 0.001), TNM stage (I vs. II–III: OR = 0.45, 95% CI:0.34–0.60, p = 0.000), smoking status (Yes vs No: OR = 1.43, 95% CI:1.14–1.80, p = 0.002) and lymph node metastasis (N+ vs N−: OR = 1.97, 95% CI:1.26–3.08, p = 0.003).ConclusionsThe results of this meta-analysis suggest that PD-L1 expression predicts an unfavorable prognosis in early stage resected NSCLCs. The role of personalized anti-PD-L1/PD-1 immunotherapy in the adjuvant settings of resected NSCLC warrants further investigation.

9609 Background: Targeted therapy in EGFR and ALK mutated non-small cell lung cancer (NSCLC) has been the standard of care for nearly a decade with subsequent FDA approvals for ROS1 and BRAF V600 mutated NSCLC occurring in 2016 and 2017. However, recent studies have shown suboptimal utilization of genomic profiling results in these patients. In 1 recent study of community oncologists, ~70% of EGFR/ALK+ patients received appropriate targeted therapy, while patients with other gene mutations (including BRAF and ROS1) only received targeted therapy ~30% of the time. Left unanswered was what patients were receiving instead and why. Additionally, it is unknown if this finding is generalizable to the academic setting. We aimed to investigate whether in our patient population, NSCLC patients with actionable mutations received associated FDA approved therapies and if not why. Methods: The pathology database was queried for all NSCLC with molecular testing (including qPCR, FISH and NGS) from 2009 to 2019. Patients with sensitizing EGFR, ALK, ROS1 or BRAF mutations that were detected after the first FDA approval for their respective targeted therapies were included for analysis with those lost to follow up subsequently excluded. Basic demographic and clinical variables were collected as well as treatment records. Results: 2160 NSCLC patients were evaluated (2160 EGFR, 1417 ALK, 810 ROS1, 589 BRAF). 468 patients were identified with targetable mutations (411 EGFR, 46 ALK, 5 ROS1, 6 BRAF). No patient had more than 1 targetable mutation. Of those patients, 248 were at an advanced stage and had clinical follow up (202 EGFR, 37 ALK, 4 ROS1, 5 BRAF). Of those patients 197/202 (97.5%), 33/37 (89.2%), 3/4 (75%) and 1/5 (20%) received EGFR, ALK, ROS1 or BRAF targeted therapy respectively. Across biomarkers 14/248 patients (5.6%) did not receive subsequent targeted therapy. 10 patients (5 EGFR, 3 ALK, 1 ROS1 and 1 BRAF) passed away before targeted therapy could be initiated. Physician choice and missed findings accounted for the remaining four cases. Conclusions: The vast majority of advanced NSCLC patients analyzed in this study received appropriate targeted therapy matched to genomic findings. The main reason (~4% of total cases) that patients did not receive therapy was due to rapidly progressive disease and death before it could be initiated. These findings are at odds with those published from the community setting. This may be due to multiple factors, including clinician education, ease of access to targeted therapies across patient populations and incomplete data in the previous study populations.

e20528 Background: Given the rising number of immunotherapy or targeted therapy trials, a call for real-world treatment (Tx) data among resectable non-small cell lung cancer (NSCLC) patients is needed. We describe Tx patterns and timelines to Tx. Methods: Retrospective data were collected from the SEER Medicare database. Patient inclusion criteria: newly diagnosed NSCLC stages IA to IIIB between 2010 and 2015, ≥65 years of age, and continuously enrolled in Medicare Part A and B and no HMO enrollment for ≥7 months prior to diagnosis (Dx) date. A subset of patients with a follow-up of ≥12 months after Dx or ≥6 months after surgery were evaluated for Tx patterns. Results: Among 31,921 NSCLC patients identified, the mean (SD) age was 76 (7) years and 51% were female. AJCC (7th edition) stages included IA (25%), IB (21%), II (8%), IIIA (17%), and IIIB (30%). Among the 6,559 (21%) patients identified with a solitary pulmonary nodule (SPN) prior to Dx, the median [IQR] time from SPN to Dx was 29 [13, 67] days. Among the 24,952 (78%) patients who received Tx, the median [IQR] time from Dx to Tx was 31 [14, 54] days. Among 19,304 patients included in the Tx pattern analysis, 63% did not undergo surgery. Among resected patients with lymph node metastasis, only 64% (stage II), 74% (stage IIIA), and 52% (stage IIIB) of patients received chemotherapy (CT) before or after surgery (Table). Median [IQR] time in days between Dx and neoadjuvant or adjuvant CT was 29 [14, 48] and 84 [56, 119], respectively. Median [IQR] time in days between Dx and surgery was longer for patients with neoadjuvant Tx (Table). Median [IQR] time between surgery to adjuvant CT was 46 [33, 63] days, with 59% of patients receiving their adjuvant CT ≥ 6 weeks after surgery and 33% of patients receiving their adjuvant CT ≥ 8 weeks after surgery. Conclusions: A significant proportion of lymph node positive stage II or III NSCLC patients did not receive perioperative systemic therapy despite standard of care guidelines. This finding suggests a patient population with unmet need notwithstanding recommendations for systemic therapy. [Table: see text]
