Advanced gastric and gastroesophageal junction cancer (G/GEJC) poses significant therapeutic challenges. Immune checkpoint inhibitors, particularly targeting programmed cell death ligand-1 (PD-L1), have emerged as promising agents to enhance patient outcomes. This meta-analysis evaluates the efficacy of PD-L1 inhibitors compared to chemotherapy in patients with advanced G/GEJC characterised by varying combined positive scores (CPS).

Background: Immune checkpoint inhibitors (ICIs) have become the recommended first-line treatment for advanced non-small cell lung cancer (NSCLC) without driver gene mutations. However, data on the failure patterns of first-line ICIs monotherapy is limited, and the optimal strategy for subsequent treatment remains controversial.

Methods: Advanced NSCLC patients receiving first-line ICIs monotherapy at Guangdong Lung Cancer Institute between December 2017 and October 2021 were identified.

Article Synopsis
  • Transformation to small cell lung cancer (SCLC) is a resistance mechanism seen in lung adenocarcinoma (LUAD) patients treated with tyrosine kinase inhibitors, particularly in those with leptomeningeal metastases (LM).
  • In a study of 237 non-small cell lung cancer (NSCLC) patients who had lumbar punctures, SCLC cells were identified in the cerebrospinal fluid (CSF) of 8 patients, all of whom showed resistance to targeted therapies.
  • The results suggest that SCLC transformation in CSF can be detected using cytological evaluation and ctDNA analysis, providing valuable insights into treatment resistance mechanisms, with this transformation correlating with reduced survival rates.

Background: With the rapid progress of systematic therapy for hepatocellular carcinoma (HCC), therapeutic strategies combining hepatic arterial infusion chemotherapy (HAIC) with systematic therapy arised increasing concentrations. However, there have been no systematic review comparing HAIC and its combination strategies in the first-line treatment for advanced HCC.

Aim: To investigate the efficacy and safety of HAIC and its combination therapies for advanced HCC.

Article Synopsis
  • * Single-cell RNA sequencing revealed that LMs contain diverse macrophage populations with stronger immunosuppressive characteristics, particularly a subset linked to osimertinib resistance influenced by Midkine (MDK).
  • * Elevated MDK levels in cerebrospinal fluid and plasma correlate with worse patient outcomes, suggesting MDK and the RNASE1_M macrophage subtype could be potential targets for treating LMs in NSCLC patients.

Background: Recent evidence suggests that insulin resistance affects asthma outcomes. However, the effect of the homeostatic measure of insulin resistance (HOMA-IR) on airway inflammation and asthma exacerbations (AEs) is poorly understood.

Objective: To analyze the relationship between HOMA-IR and clinical and inflammatory characteristics in patients with asthma, and the association between HOMA-IR and AEs in the following year.

Background: The calcium-binding protein 4 () gene is a newly identified epilepsy-related gene that might be associated with a rare type of genetic focal epilepsy; that is, autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE). , mutant CABP4 causes an increased inward flow voltage of calcium ions and a significant increase in the electrical signal discharge in hippocampus neurons; however, the role of in epilepsy has not yet been specifically described, and there is not yet a CABP4 mutant animal model recapitulating the epilepsy phenotype.

Methods: We introduced a human missense mutation into the C57BL/6J mouse genome and generated a knock-in strain carrying a glycine-to-aspartic acid mutation in the gene.

Article Synopsis
  • * This study introduces a nickel-catalyzed method for these coupling reactions, successfully creating chiral amines with high enantioselectivity and decent linear selectivity.
  • * The method works well with a variety of aliphatic alkenes, including those from biologically active compounds, thanks to new chiral spiro phosphine ligands that enhance the reaction.

Article Synopsis
  • * LUAD can be categorized into two metabolic phenotypes: redox and non-redox, with significant differences in mutation prevalence and immune cell response; redox LUAD primarily features mutations in KEAP1, STK11, NRF2, and SMARCA4.
  • * Patients with the redox phenotype show poorer response rates, progression-free survival, and overall survival when treated with ICIs, largely due to a reduction in tissue-resident memory CD8+ T cells.

Background: The effects of gut microbiota and metabolites on the responses to immune checkpoint inhibitors (ICIs) in advanced epidermal growth factor receptor (EGFR) wild-type non-small cell lung cancer (NSCLC) have been studied. However, their effects on EGFR-mutated (EGFR +) NSCLC remain unknown.

Methods: We prospectively recorded the clinicopathological characteristics of patients with advanced EGFR + NSCLC and assessed potential associations between the use of antibiotics or probiotics and immunotherapy efficacy.

Background: Tertiary lymphoid structures (TLSs) affect the prognosis and efficacy of immunotherapy in patients with non-small cell lung cancer (NSCLC), but the underlying mechanisms are not well understood.

Methods: TLSs were identified and categorized online from the Cancer Digital Slide Archive (CDSA). Overall survival (OS) and disease-free survival (DFS) were analyzed.

Introduction: EGFR C797X (C797S or C797G) mutation is the most frequent on-target mechanism of resistance to osimertinib. The hypothesis that the allelic context of C797X/T790M has implications for treatment is on the basis of sporadic reports and needs validation with larger cohorts.

Methods: We identified patients with EGFR C797X-mutant NSCLC from nine centers who progressed on osimertinib, all analyzed in a single laboratory through next-generation sequencing.

Background: The liver is a frequent site of metastases and liver metastases (LM) correlate with diminished immunotherapy efficacy in non-small cell lung cancer (NSCLC). This study aimed to analyze whether tumor response to immunotherapy differs between pulmonary lesions (PL) and LM in NSCLC and to explore potential mechanisms through multiomics analysis.

Methods: This observational longitudinal clinical cohort study included patients with NSCLC with LM receiving immunotherapy was conducted to evaluate organ-specific tumor response of PL and LM.

Mutations in epidermal growth factor receptor and anaplastic lymphoma kinase are common driver events in non-small cell lung cancer (NSCLC), which are associated with a high frequency of bone metastases (BMs). While the bone marrow represents a specialized immune microenvironment, the immune repertoire of BMs remains unknown. Considering the higher incidence of BMs in driver gene-positive NSCLCs, and the unique biology of the bone, herein, we assessed the infiltrating immune cells and T cell receptor (TCR) profile of BMs in driver-positive NSCLCs.

  • Wilms' tumour (WT) is a common type of kidney cancer in kids that often comes back after treatment and has a low chance of survival.
  • Researchers studied a special molecule called EMX2OS to see how it affects WT cells by interacting with another molecule called IGF2BP1.
  • They found that increasing EMX2OS helps stop WT cells from growing and spreading, making it a potential new way to help diagnose and treat this cancer.

Article Synopsis
  • A study was conducted to explore the relationship between self-reported sleep duration and asthma outcomes, particularly focusing on clinical and inflammatory characteristics over a 1-year period.
  • Participants with short sleep duration (58), normal (380), and long sleep duration (84) were analyzed, revealing that those with short sleep were older, had lower IgE and FeNO levels, but higher airway inflammation markers.
  • Short sleep duration was found to increase the risk of poorly controlled asthma and moderate to severe asthma exacerbations, suggesting that sleep duration could be an important factor in asthma management.
