BACKGROUND: Durvalumab supplementation may have some potential in improving the efficacy in patients with non-small-cell lung cancer (NSCLC), and this meta-analysis aims to explore the impact of durvalumab supplementation on efficacy for NSCLC.
METHODS: PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases were systematically searched, and we included randomized controlled trials (RCTs) assessing the effect of durvalumab supplementation on efficacy in patients with NSCLC. Overall survival and progression-free survival were included for this meta-analysis.
RESULTS: Four RCTs were finally included in the meta-analysis. Overall, compared with control group for NSCLC, durvalumab supplementation showed significantly improved survival rate (odd ratio [OR] = 1.64; 95% confidence interval [CI] = 1.31 to 2.06; P < 0.0001), overall survival ( hazard ratio [HR] = 0.73; 95% CI = 0.61 to 0.87; P = 0.0003), progression-free survival rate (OR = 2.31; 95% CI = 1.78 to 3.01; P < 0.00001) and progression-free survival (HR = 0.71; 95% CI = 0.54 to 0.95; P = 0.02), and had the capability to reduce the incidence of grade ≥ 3 adverse events (OR = 0.26; 95% CI = 0.16 to 0.42; P < 0.00001).
CONCLUSIONS: Durvalumab supplementation is effective to improve the efficacy for NSCLC.

BACKGROUND: Third-generation epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) have significant antitumor activity to advanced non-small-cell lung cancer (NSCLC) patients with classic EGFR mutations. However, EGFR-TKI monotherapy shows poor efficacy in patients whose circulating tumor cell DNA (ctDNA) of EGFR mutations cannot be rapidly cleared.
METHODS: As a third-generation TKI, furmonertinib has shown superior antitumor activity and minor toxicity. The FOCUS-C study is a prospective, multicenter, randomized controlled trial (NCT05334277) to explore the efficacy and safety of furmonertinib plus pemetrexed-platinum doublet chemotherapy with or without bevacizumab versus furmonertinib monotherapy in untreated advanced EGFR mutant NSCLC patients without EGFR clearance after the induction therapy of furmonertinib. Patients with EGFR clearance will still receive furmonertinib as Arm A. Patients without ctDNA clearance will be randomized in a 2:2:1 ratio as Arm B1 (furmonertinib), Arm B2 (furmonertinib combined with carboplatin and pemetrexed for 4 cycles, and then furmonertinib and pemetrexed as maintenance therapy) and Arm B3 (Arm B2 regimen plus bevacizumab). The primary endpoint is progression-free survival (PFS) in Arm B2/B1. Secondary endpoints include PFS in Arm B3/B1, PFS in Arm A/B1, PFS in Arm B3/B2, objective response and disease control rate, overall survival and safety in all Arms. Exploratory endpoints are focused on the efficacy based on plasma NGS at different timepoints.
CONCLUSIONS: This study will evaluate the efficacy and tolerability of furmonertinib plus carboplatin and pemetrexed with or without bevacizumab verses furmonertinib alone in untreated patients with advanced EGFR mutant NSCLC without EGFR clearance.

BACKGROUND: Lazertinib is a third-generation tyrosine kinase inhibitor of epidermal growth factor receptor (EGFR-TKI) that selectively inhibit common EGFR mutation and T790M mutation in non-small-cell lung cancer (NSCLC) patients. No previous studies have compared lazertinib to platinum-based chemotherapy. We have compared lazertinib with platinum-based chemotherapy in EGFR-mutated NSCLC patients after previous EGFR-TKI therapy.
METHODS: We retrospectively compared 200 patients from LASER201, LASER301, and LASER-PMS studies to 334 patients who were treated with platinum-based chemotherapy after previous EGFR-TKI from the Samsung Medical Center. After propensity score matching (PSM), we selected 156 patients from each group. The primary outcome was progression-free survival (PFS), with overall survival (OS), objective response rate (ORR), and time to treatment discontinuation (TTD) as secondary outcomes.
RESULTS: The median follow-up of PFS was 15.61 months in the lazertinib group and 21.67 months in the external control group. The PFS was significantly longer in patients who were treated with lazertinib than those treated with platinum-based chemotherapy (10.97 months vs. 5.10 months; adjusted hazard ratio (HR) 0.40; 95% confidence interval (CI), 0.29-0.55; p < 0.01) after PSM. Lazertinib showed superior OS (32.23 months vs. 18.73 months; adjusted HR 0.45; 95% CI, 0.29-0.69; p < 0.001), ORR (64.1% vs. 47.4%), and TTD (11.66 months vs. 6.73 months; adjusted HR 0.54; 95% CI, 0.39-0.75; p < 0.001) compared to platinum-based chemotherapy.
CONCLUSIONS: Based on this retrospective, external control study, lazertinib has demonstrated significantly better efficacy compared with platinum-based chemotherapy. The external controls provide important context to evaluate efficacy in single-arm studies.

BACKGROUND: It is unclear whether the sequential administration of programmed death (PD)-1/programmed death-ligand 1 (PD-L1) inhibitors and epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) is associated with the development of severe interstitial pneumonitis (IP).
METHODS: We identified 69,107 eligible patients with non-small cell lung cancer (NSCLC) from a Japanese national inpatient database, who initiated EGFR-TKI therapy. The study population was divided into the PD-1/PD-L1 inhibitor and non-prior PD-1/PD-L1 groups based on PD-1/PD-L1 administration before EGFR-TKI therapy. We conducted 1:4 matched-pair cohort analyses (n = 9,725) to compare the incidence of IP and in-hospital mortality within 90 days of administration of EGFR-TKI between the two groups after adjusting for the clinical background. Furthermore, we performed subgroup analyses categorized according to the duration of prior PD-1/PD-L1 inhibitor use.
RESULTS: IP occurred in 4.4% of patients in the matched-pair cohort. PD-1/PD-L1 inhibitor-use before EGFR-TKI therapy was significantly associated with IP (odds ratio [OR], 1.79; 95% confidence interval [CI], 1.34-2.38) and in-hospital mortality (OR, 2.10; 95% CI, 1.72-2.55). Prior PD-1/PD-L1 inhibitor use in an interval of <6 months before EGFR-TKI administration was associated with a higher risk of IP than EGFR-TKI administration without prior PD-1/PD-L1 inhibitor. In-hospital mortality was higher in patients with prior PD-1/PD-L1 inhibitor use than that in those without prior PD-1/PD-L1 inhibitor use, irrespective of the treatment duration.
CONCLUSIONS: Sequential use of PD-1/PD-L1 inhibitors and EGFR-TKIs in patients with non-small cell lung cancer was significantly associated with IP compared to EGFR-TKIs without prior PD-1/PD-L1 inhibitor administration.

BACKGROUND: Osimertinib represents the standard of care for the treatment of advanced non-small-cell lung cancer (NSCLC) harboring classical epidermal growth factor receptor (EGFR) mutations, constituting 80%-90% of all EGFR alterations. In the remaining cases, an assorted group of uncommon alterations of EGFR (uEGFR) can be detected, which confer variable sensitivity to previous generations of EGFR inhibitors, overall with lower therapeutic activity. Data on osimertinib in this setting are limited and strongly warranted.
METHODS: The ARTICUNO study retrospectively evaluated data on osimertinib activity from patients with advanced NSCLC harboring uEGFR treated in 21 clinical centers between August 2017 and March 2023. Data analysis was carried out with a descriptive aim. Investigators collected response data according to RECIST version 1.1 criteria. The median duration of response, progression-free survival (mPFS), and overall survival were estimated by the Kaplan-Meier method.
RESULTS: Eighty-six patients harboring uEGFR and treated with osimertinib were identified. Patients with \'major\' uEGFR, that is, G719X, L861X, and S768I mutations (n = 51), had an overall response rate (ORR) and mPFS of 50% and 9 months, respectively. Variable outcomes were registered in cases with rarer \'minor\' mutations (n = 27), with ORR and mPFS of 31% and 4 months, respectively. Among seven patients with exon 20 insertions, ORR was 14%, while the best outcome was registered among patients with compound mutations including at least one classical EGFR mutation (n = 13). Thirty patients presented brain metastases (BMs) and intracranial ORR and mPFS were 58% and 9 months, respectively. Amplification of EGFR or MET, TP53 mutations, and EGFR E709K emerged after osimertinib failure in a dataset of 18 patients with available rebiopsy.
CONCLUSIONS: The ARTICUNO study confirms the activity of osimertinib in patients with uEGFR, especially in those with compound uncommon-common mutations, or major uEGFR, even in the presence of BMs. Alterations at the E709 residue of EGFR are associated with resistance to osimertinib.

UNASSIGNED: As one of the most prevalent primary lung tumors, non-small cell lung cancer (NSCLC) has garnered considerable research interest due to its high metastasis rates and poor prognosis outcomes. Across different cancer types, metabolic processes are required for tumors progression and growth, thus interfering with such processes in NSCLC may therapeutically viable for limiting/halting disease progression. Therefore, comprehending how metabolic processes contribute to growth and survival mechanisms in cancers, including NSCLC, may elucidate key functions underpinning tumor cell metabolism. However, no bibliometric analyses have been published in this field, therefore we address this knowledge gap here.
UNASSIGNED: Between 2013 and 2023 (December 28th), articles related to the NSCLC and metabolism (NSCLC-Met) field were retrieved from the Web of Science Core Collection (WoSCC). To fully dissect NSCLC-Met research directions and articles, we used the Bibliometrix package in R, VOSviewer and CiteSpace software to visually represent global trends and hotspots.
UNASSIGNED: Between 2013 and 2023, 2,246 NSCLC-Met articles were retrieved, with a continuous upward trend and rapid development observed year on year. Cancers published the most articles, with Cancer Research recording the highest average citation numbers. Zhang Li from China was the most prolific author, but the highest number of authors came from the USA. China, USA, and Italy were the top three countries with the highest number of published articles, with close cooperation identified between countries. Recent hotspots and research directions were reflected by \"lung adenocarcinoma\", \"immunotherapy\", \"nivolumab\", \"checkpoint inhibitors\", \"blockade\", and \"pembrolizumab\", while \"gut microbiome\", \"egfr\" and \"dose painting\" were important topics for researchers.
UNASSIGNED: From our analyses, scientists can now explore new hotspots and research directions in the NSCLC-Met field. Further in-depth research in this field will undoubtedly provide more new insights on disease diagnostics, treatment, and prognostics.

BACKGROUND: Resistance to immune checkpoint inhibitors (ICIs) represents a major unmet medical need in non-small cell lung cancer (NSCLC) patients. Vascular endothelial growth factor (VEGF) inhibition may reverse a suppressive microenvironment and recover sensitivity to subsequent ICIs.
METHODS: This phase Ib/IIa, single-arm study, comprised dose-finding (Part A) and expansion (Part B) cohorts. Patients with ICIs-refractory NSCLC were enrolled to receive anlotinib (a multi-target tyrosine kinase inhibitor) orally (from days 1 to 14 in a 21-day cycle) and nivolumab (360 mg every 3 weeks, intravenously) on a 21-day treatment cycle. The first 21-day treatment cycle was a safety observation period (phase Ib) followed by a phase II expansion cohort. The primary objectives were recommended phase 2 dose (RP2D, part A), safety (part B), and objective response rate (ORR, part B), respectively.
RESULTS: Between November 2020 and March 2022, 34 patients were screened, and 21 eligible patients were enrolled (6 patients in Part A). The RP2D of anlotinib is 12 mg/day orally (14 days on and 7 days off) and nivolumab (360 mg every 3 weeks). Adverse events (AEs) of any cause and treatment-related AEs (TRAEs) were reported in all treated patients. Two patients (9.5%) experienced grade 3 TRAE. No grade 4 or higher AEs were observed. Serious AEs were reported in 4 patients. Six patients experienced anlotinib interruption and 4 patients experienced nivolumab interruption due to TRAEs. ORR and disease control rate (DCR) was 19.0% and 76.2%, respectively. Median PFS and OS were 7.4 months (95% CI, 4.3-NE) and 15.2 months (95% CI, 12.1-NE), respectively.
CONCLUSIONS: Our study suggests that anlotinib combined with nivolumab shows manageable safety and promising efficacy signals. Further studies are warranted.
BACKGROUND: NCT04507906 August 11, 2020.

UNASSIGNED: EGFR exon 20 insertion (ex20ins) mutations account for approximately 10% of EGFR mutations in lung adenocarcinoma. Patients with ex20ins mutation do not respond to standard EGFR tyrosine kinase inhibitor therapy. In this work, we analyzed the characteristics, treatment patterns, and outcomes in this subgroup of patients with NSCLC.
UNASSIGNED: The American Society of Clinical Oncology CancerLinQ Discovery data set was queried to identify patients with initial diagnosis of NSCLC between the years 1995 and 2018 and with EGFR ex20ins mutations. Data were extracted on patient demographics, tumor characteristics, treatments, and outcomes, and compared using chi-square and analysis of variance. Kaplan-Meier curves were generated to compare overall survival with log-rank tests. All analyses were performed using Python 3.6 (Python Software Foundation).
UNASSIGNED: A total of 357 patients were eligible. Patient characteristics include a median age of 68 years comprising female sex of 54%, White race of 63%, and Black race of 9%. Approximately 62% of total patients had stage 4 disease, and 30% of all patients had brain metastasis. There were 54% of patients who were treated with chemotherapy and 15% with immune checkpoint inhibitors (ICIs). In patients with brain metastasis, 16% were treated with ICI, 18% with targeted therapy, and 59% with chemotherapy. The median survival of the entire group was 23.8 months. Among patients with stage 4 disease (n = 222): 51% were women, 64% were white, 37% had brain metastasis, 18% were treated with ICI, 14% had targeted therapy, and 60% were treated with chemotherapy. Stage 4 patients treated with targeted therapy had better survival compared with those who did not receive targeted therapy (20.6 versus 16.1 mo, p = 0.02). Univariate and multivariate analyses suggested favorable outcomes for patients treated with immunotherapy.
UNASSIGNED: EGFR ex20ins mutation represents a unique subset of NSCLC; it is associated with a higher propensity for brain metastases and a relatively modest overall survival. Novel treatment approaches are urgently needed to improve patient outcomes.

Non-small cell lung cancer (NSCLC) is a complex malignancy with a high degree of heterogeneity, representing approximately 85% of all lung cancer cases. The treatment landscape for NSCLC has been revolutionised by incorporating targeted and immunotherapies; however, novel therapeutic modalities are consistently needed to enhance the treatment outcomes. Indeed, alternative anti-cancer therapies involving natural products have drawn the attention of clinicians and scientists owing to their remarkable chemopreventive potential, often displaying minimal toxicity. D-carvone (CN) is one such natural product that has exhibited numerous promising therapeutic benefits, yet its efficacy against NSCLC remains enigmatic. In the present study, network pharmacological studies and molecular docking in conjunction with in-vitro validation were used to elucidate the underlying mechanism of action of CN comprehensively. Different databases revealed a total of 77 putative anti-NSCLC targets of CN. The identified core targets were utilised to construct a \"Compound- Target- Disease\" network by Cytoscape (v3.9.0). Further analysis identified 5 core/ hub targets of CN including JAK2, ERK1, ESR1, GSK3B and HSP90AA1. Molecular docking indicated a strong binding interaction of the compound with these core targets. Also, Gene Ontology and KEGG analysis validated the involvement of multiple biological processes. Additionally, CN significantly inhibited cell proliferation, clonogenicity, and wound healing potential while promoting apoptosis in a dose-dependent manner in H1299 and A549 cell lines as examined by flow cytometry, morphological assessment, and western blotting. In conclusion, this study delineates the therapeutic effects of CN on NSCLC, thus highlighting CN as a putative drug candidate for further analysis.

BACKGROUND: Non-small cell lung cancer (NSCLC) harboring ROS1 rearrangements is a molecular subset that exhibits favorable responses to tyrosine kinase inhibitor (TKI) treatment than chemotherapy. This study investigated real-world treatment patterns and survival outcomes among patients with ROS1-rearranged advanced NSCLC.
METHODS: We conducted a retrospective analysis of patients with ROS1-rearranged advanced NSCLC treated in four different hospitals in China from August 2018 to March 2022. The study analyzed gene fusion distribution, resistance patterns, and survival outcomes.
RESULTS: ROS1 rearrangement occurs in 1.8 % (550/31,225) of our study cohort. CD74 was the most common ROS1 fusion partner, accounting for 45.8 %. Crizotinib was used in 73.9 % of patients in the first-line treatment, and an increased use of chemotherapy, ceritinib, and lorlatinib was seen in the second-line setting. Lung (43.2 %) and brain (27.6 %) were the most common sites of progression in first-line setting, while brain progression (39.2 %) was the most common site of progression in second-line. Median overall survival was 46 months (95 % confidence intervals: 39.6-52.4). First-line crizotinib use yielded significantly superior survival outcomes over chemotherapy in terms of progression-free (18.5 vs. 6.0; p < 0.001) and overall survival (49.8 vs. 37; p = 0.024). The choice of treatment in the latter line also had survival implications, wherein survival outcomes were better when first-line crizotinib was followed by sequential TKI therapy than first-line chemotherapy followed by TKI therapy.
CONCLUSIONS: Our study provided insights into the real-world treatment, drug resistance patterns, and survival outcomes among patients with ROS1-rearranged NSCLC. This information serves as a valuable reference for guiding the treatment of this molecular subset of NSCLC.
