Glecirasib (JAB-21822) is a new covalent oral KRAS-G12C inhibitor. This multicenter, single-arm phase 2b study assessed the efficacy and safety of glecirasib administered orally at 800 mg daily in patients with locally advanced or metastatic KRAS-mutated nonsmall-cell lung cancer. The primary endpoint was the objective response rate (ORR) assessed by an independent review committee (IRC).

  • A phase 3 study showed that combining camrelizumab with chemotherapy significantly improved progression-free survival in patients with advanced non-squamous non-small-cell lung cancer compared to chemotherapy alone.
  • After 5 years, overall survival rates were 31.2% for those receiving camrelizumab and chemotherapy versus 19.3% for those on chemotherapy alone, indicating a substantial benefit.
  • Patients who completed two years of treatment with camrelizumab had an impressive 5-year overall survival rate of 84.3%, reinforcing its effectiveness and safety as a first-line therapy for this cancer type.

Ferromagnetism in the two-dimensional limit has become an intriguing topic for exploring new physical phenomena and potential applications. To induce ferromagnetism in 2D materials, intercalation has been proposed to be an effective strategy, which could introduce lattice distortion and unpaired spin into the material to modulate the magnetocrystalline anisotropy and magnetic exchange interactions. To strengthen the understanding of the magnetic origin of 2D material, Cu was introduced into a 2D WO through chemical intercalation in this work (2D Cu/WO).

Background: Cholangiocarcinoma (CCA), characterized by high heterogeneity and extreme malignancy, has a poor prognosis. Doublecortin-like kinase 1 (DCLK1) promotes a variety of malignant cancers in their progression. Targeting DCLK1 or its associated regulatory pathways can prevent the generation and deterioration of several malignancies.

Purpose: The variable responses to immunotherapy observed in gastric cancer (GC) patients can be attributed to the intricate nature of the tumor microenvironment. Glutathione (GSH) metabolism significantly influences the initiation and progression of gastric cancer. Consequently, targeting GSH metabolism holds promise for improving the effectiveness of Immune checkpoints inhibitors (ICIs).

The effectiveness of an elemental diet (ED) for preventing adverse events (AEs) during chemotherapy for patients with esophageal cancer (EC) remains unclear. The aim of this meta-analysis was to comprehensively assess the efficacy of ED for preventing AE in EC patients during chemotherapy. Medline (via PubMed), Embase, the Cochrane Library, and Web of Science were searched to retrieve prospective and randomized studies published before April 12, 2023.

Surface Enhanced Raman spectroscopy (SERS) is a molecular-specific analytical technique with various applications. Although electromagnetic (EM) and chemical (CM) mechanisms have been proposed to be the main origins of SERS, exploring highly sensitive SERS substrates with well-defined mechanistic pathways remains challenging. Since surface and electronic structures of substrates were crucial for SERS activity, zero-valent transition metals (Fe and Cu) were intercalated into MoO to modulate its surface and electronic structures, leading to unexceptional high enhancement factors (1.

Article Synopsis
  • Immune checkpoint inhibitors, particularly PD-1 antibodies, have been shown to effectively prevent tumor growth in patients with early-stage esophageal squamous cell carcinoma (ESCC) and high-grade intraepithelial neoplasia (HGIN).
  • The study utilized a mouse model to compare the effects of PD-1 antibody treatment at different cancer stages, showing that preventive treatment significantly halted the progression of tumors induced by a carcinogen.
  • Findings reveal that PD-1 treatment promotes the presence of memory T cells in the tumor environment, suggesting potential long-term benefits for prophylactic use in early ESCC stages, although clinical applications are currently lacking.

Background: Immune checkpoint inhibitor (ICI) treatment has enhanced survival outcomes in clear cell renal cell carcinoma (ccRCC) patients. Nevertheless, the effectiveness of immunotherapy in ccRCC patients is restricted and we intended to develop and characterize an immune response prediction signature (IRPS) to forecast the efficacy of immunotherapy.

Methods: RNA-seq expression profile and clinicopathologic characteristics of 539 kidney cancer and 72 patients with normal specimens, were downloaded from the Cancer Genome Atlas (TCGA) database, while the Gene Expression Omnibus (GEO) database was used as the validation set, which included 24 ccRCC samples.

Objective: Epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) is a first-line treatment for lung adenocarcinoma with EGFR-sensitive mutations, but acquired resistance to EGFR-TKIs remains a problem in clinical practice. The development of epithelial-mesenchymal transition (EMT) is a critical mechanism that induces acquired resistance to TKIs. Reversing acquired resistance to EGFR-TKIs through targeting the key molecules driving EMT provides an alternative choice for patients.

Triple-negative breast cancer (TNBC) exhibits the poorest outcomes among breast cancer subtypes due to the high heterogeneity and a lasting scarcity of effectual treatments. Targeted therapies based on molecular subtypes of TNBC are critical step toward tailoring treatments to improve clinical outcomes. Gastrointestinal cancer stem cell (CSC) marker DCLK1 was reported to be highly expressed in stem cell-rich subtype of TNBC.

Article Synopsis
  • A meta-analysis was conducted to compare the effectiveness of immune checkpoint inhibitors (ICIs) versus chemotherapy in lung cancer patients with specific metastatic sites, namely liver and brain metastases.
  • The analysis included data from 24 randomized controlled trials, involving 1,124 patients with brain metastases and 2,077 with liver metastases, and found that those with liver metastases derived less benefit from ICIs compared to those without.
  • The study concluded that while immunotherapy can be effective for lung cancer patients, particularly those with non-small cell lung cancer (NSCLC) and brain metastases, the overall survival benefits are diminished for patients with liver metastases and small cell lung cancer.

Decomposition of the polycation AlO(OH)(HO) (Al) promoted by ligand is a vital subject to advance our understanding of natural and artificial occurrence and evolution of aluminum ions, especially in the case of acidic condition that dissolved Al species can be released from the Al-bearing substances. However, the microscopic pathway of synchronous proton-promoted and ligand-promoted decomposition process for Al is still in the status of ambiguity. Herein, we applied differential mass spectrometry method and DFT calculation to study the initial detailed process of Al decomposition under the presence of proton and salicylic acid (HSal).

Background & Aims: Gastrointestinal cancer stem cell marker doublecortin-like kinase (DCLK1) is strongly associated with poor outcomes in colorectal cancer (CRC). Although DCLK1's regulatory effect on the tumor immune microenvironment has been hypothesized, its mode of action has not been shown previously in vivo, which hampers the potential intervention based on this molecule for clinical practice.

Methods: To define the immunomodulatory mechanisms of DCLK1 in vivo, we generated DCLK1 tumor cells by Clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated protein 9 (Cas9) and developed subcutaneous and intestinal orthotopic transplantation tumor models.

Pulmonary sarcomatoid carcinoma (PSC) is a rare subtype of nonsmall cell lung cancer with a poor prognosis. This study aimed to analyze the clinicopathological characteristics and survival outcomes among patients with PSC, lung squamous cell cancer (SCC), and lung adenocarcinoma (LAC), and to construct a competing risk nomogram for patients with PSC. Data of 3 groups of patients diagnosed with PSC, SCC, or LAC from the surveillance, epidemiology, and end results (SEER) database between 1988 and 2015 were retrospectively reviewed.

Lung adenocarcinoma is the most common form of lung cancer, accounting for 60% of non-small cell lung cancer (NSCLC) cases in Asian patients. Importantly, nearly half of these patients have epithelial growth factor receptor (EGFR) mutations. Though EGFR-tyrosine kinase inhibitors (EGFR-TKIs) are recommended as the first-line therapy for NSCLC patients, the development of resistance reduces their efficiency and limits their application.
