Article Synopsis
  • A study called ANEAS compared two cancer treatments, aumolertinib and gefitinib, for patients with advanced lung cancer that had spread to the brain.
  • The results showed that aumolertinib worked much better, helping patients live longer without their brain cancer getting worse compared to gefitinib.
  • Overall, more patients treated with aumolertinib responded well to the treatment, showing an improvement in their condition compared to those who received gefitinib.

Article Synopsis
  • Immunochemotherapy is the main treatment for extensive-stage small-cell lung cancer (ES-SCLC), and adding anti-angiogenesis may enhance its effectiveness.
  • The ETER701 trial tested a new treatment combining benmelstobart (a PD-L1 inhibitor) and anlotinib (an anti-angiogenic drug) with standard chemotherapy in newly diagnosed ES-SCLC patients.
  • The results showed that those receiving benmelstobart and anlotinib had significantly longer overall survival compared to the standard chemotherapy alone, with manageable side effects, indicating this combination could be a promising first-line treatment.

To date, few studies have investigated whether the RNA-editing enzymes adenosine deaminases acting on RNA (ADARs) influence RNA functioning in lung adenocarcinoma (LUAD). To investigate the role of ADAR in lung cancer, we leveraged the advantages of The Cancer Genome Atlas (TCGA) database, from which we obtained transcriptome data and clinical information from 539 patients with LUAD. First, we compared ARAR expression levels in LUAD tissues with those in normal lung tissues using paired and unpaired analyses.

Purpose: PD-1 blockade plus chemotherapy has become the new standard of care in patients with untreated advanced non-small cell lung cancer (NSCLC), whereas predictive biomarkers remain undetermined.

Experimental Design: We integrated clinical, genomic, and survival data of 427 NSCLC patients treated with first-line PD-1 blockade plus chemotherapy or chemotherapy from two phase III trials (CameL and CameL-sq) and investigated the predictive and prognostic value of HLA class I evolutionary divergence (HED).

Results: High HED could predict significantly improved objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) in those who received PD-1 blockade plus chemotherapy [in the CameL trial, ORR: 81.

Background: Lung cancer is a common malignant tumor, with, non-small cell lung cancer (NSCLC) accounting for about 80-85% of cases. This study investigated the expression of miR-137 in NSCLC tissues and cells and its effects on the migration and invasion of NSCLC cells and related mechanisms.

Methods: We collected the neoplastic and paracancerous tissues of NSCLC patients, detected the expression of miR-137 in NSCLC tissues and cell lines by real-time quantitative polymerase chain reaction (RT-qPCR), and analyzed the correlation between miR-137 expression and the clinicopathological features and survival of NSCLC.

Purpose: Aumolertinib (formerly almonertinib; HS-10296) is a novel third-generation epidermal growth factor receptor tyrosine kinase inhibitor approved in China. This double-blind phase III trial evaluated the efficacy and safety of aumolertinib compared with gefitinib as a first-line treatment for locally advanced or metastatic -mutated non-small-cell lung cancer (NSCLC; ClinicalTrials.gov identifier: NCT03849768).

Background: Extensive-stage small-cell lung cancer (ES-SCLC) is associated with poor prognosis and treatment options are scarce. Immunotherapy has shown robust clinical activity in ES-SCLC in previous phase 3 trials. We aimed to assess the efficacy and safety of adebrelimab (SHR-1316), a novel anti-PD-L1 antibody, with standard chemotherapy as a first-line treatment for ES-SCLC.

Circular RNAs (circRNAs) are associated with cancer progression. The present study aimed to examine the function of circRNA protein tyrosine phosphatase receptor type A (circRNA_PTPRA) in lung cancer cells and elucidate the underlying molecular mechanisms. The levels of circRNA_PTPRA and microRNA (miRNA/miR)-582-3p were measured in lung cancer tissue and cells using reverse transcription-quantitative polymerase chain reaction (RT-qPCR).

Background: Previously published studies have shown that circulating tumor cells (CTC) play an important role in clinical staging, efficacy monitoring and prognostic evaluation of lung cancer. The aim of the present study was to investigate the significance of simultaneous detection of multiple tumor marker protein expression and chromosome 8 aneuploid of CTC in the diagnosis and treatment of primary lung cancer.

Methods: We investigated the expression of cytokeratin 18 (CK18) and Vimentin on the surface of CTC and the aneuploidy of chromosome 8 in the peripheral blood of 24 patients with metastatic primary lung cancer, which were detected by subtraction enrichment (SE) and immunofluorescence hybridization (iFISH).

Background: Camrelizumab plus chemotherapy significantly prolonged progression-free survival (PFS) and overall survival (OS) compared to chemotherapy alone as first-line treatment in advanced lung squamous cell carcinoma (LUSC) in the phase III trial (CameL-sq), which has become an option of standard-of-cares for Chinese patients with advanced LUSC. However, the predictive biomarkers remain unknown.

Methods: Tumor tissue samples at baseline, and peripheral blood samples at baseline (pretreatment) and after two cycles of treatment (on-treatment) were prospectively collected from 270 LUSC patients from the CameL-sq study.

Introduction: Camrelizumab, a humanized immunoglobulin G4-κ monoclonal antibody against programmed cell death protein 1, has exhibited antitumor activity and tolerability across various tumors, including lung cancers. We conducted this double-blind, randomized phase 3 trial to investigate the efficacy and safety of camrelizumab or placebo plus chemotherapy as first-line treatment for patients with advanced squamous NSCLC. The predictive value of circulating tumor DNA (ctDNA) dynamics was also analyzed.

Introduction: Aumolertinib (formerly almonertinib; HS-10296) is a novel third-generation EGFR tyrosine kinase inhibitor (TKI) with revealed activity against EGFR-sensitizing mutations and EGFR T790M mutation.

Methods: Patients with locally advanced or metastatic NSCLC who developed an EGFR T790M mutation after progression on first- or second-generation EGFR TKI therapy were enrolled in this registrational phase 2 trial of aumolertinib at 110 mg orally once daily (NCT02981108). The primary end point was objective response rate (ORR) by independent central review.

Background: Serial profiling of circulating tumor DNA (ctDNA) could reflect dynamic molecular changes in response to treatment and potentially predict impending disease progression (PD). Herein, we investigated the molecular factors and dynamic changes in ctDNA that can serve as predictors of survival outcomes of patients with epidermal growth factor receptor ()-mutated advanced non-small cell lung cancer (NSCLC) who received osimertinib therapy after progression from prior EGFR inhibitor regimen.

Methods: Capture-based targeted sequencing was performed on the baseline and longitudinal plasma samples collected from 72 and 57 patients, respectively, using a 168-gene panel.

Asymptomatic SARS-CoV-2-infected individuals are thought to play major roles in virus transmission. This study aimed to analyze the characteristics of asymptomatic carriers with COVID-19 to control the spread of the virus. We retrospectively investigated the clinical characteristics of 648 consecutive subjects who were enrolled in the study and were divided into asymptomatic carriers, mild cases, ordinary cases, severe or critical cases, and evaluated their impact on disease severity by means of Spearman correlation and multiple regression analyses.

Purpose: The epithelial-to-mesenchymal transition (EMT) phenotype-based subsets of circulating tumor cells (CTCs) might be predictors of tumor progression. We evaluated the clinical properties of different phenotypic CTCs in patients with non-small cell lung cancer (NSCLC). Secondly, we explored the association between different phenotypic CTCs and the uptake of 18F-fluorodeoxyglucose (FDG) by the primary tumor on a positron emission tomographic (PET) scan.
