A randomized double-blind phase 3 trial (CHOICE-01, NCT03856411) demonstrated that combining toripalimab with chemotherapy substantially improves progression-free survival (PFS) in advanced non-small cell lung cancer (NSCLC) patients without pretreatment. This study presents the prespecified final analysis of overall survival (OS) and biomarkers utilizing circulating tumor DNA (ctDNA) and tissue-based sequencing. Additionally, the analysis revealed a higher median overall survival (OS, 23.

Purpose: We evaluated the efficacy and safety of roxadustat, a first-in-class hypoxia-inducible factor prolyl hydroxylase inhibitor, for chemotherapy-induced anemia (CIA) in patients with nonmyeloid malignancies receiving multicycle treatments of chemotherapy.

Patients And Methods: In this open-label, noninferiority phase III study conducted at 44 sites in China, 159 participants age ≥18 years with CIA nonmyeloid malignancy and CIA were randomly assigned (1:1) to oral roxadustat or subcutaneous recombinant human erythropoietin-α (rHuEPO-α) three times a week for 12 weeks. Roxadustat starting dosages were 100, 120, and 150 mg three times a week for participants weighing 40-<50, 50-60, and >60 kg, respectively.

Article Synopsis
  • There is a need for better second- and third-line treatments for advanced non-small-cell lung cancer (NSCLC) without driver mutations, prompting a clinical trial.
  • The trial involved 559 eligible patients with NSCLC who had failed first-line treatment and tested the effectiveness of docetaxel combined with either plinabulin or a placebo.
  • Results showed that the plinabulin group had a longer median overall survival (10.5 months) compared to the placebo group (9.4 months), with over 99% of patients experiencing treatment-related adverse events.

  • Research seeks to improve chemotherapy and PD-1 inhibitors for advanced non-small-cell lung cancer (NSCLC) by analyzing circulating tumor DNA (ctDNA) from 460 patients in the CHOICE-01 study.
  • Key predictive markers such as ctDNA status, tumor mutational burden, and chromosomal instability were identified to tailor treatment strategies for better patient outcomes.
  • An integrated ctDNA-based stratification system, called blood-based genomic immune subtypes (bGIS), offers a new way to personalize therapies and monitor treatment responses in advanced NSCLC patients.

The microbiome of critically ill patients is significantly altered by both effects of the illnesses and clinical interventions provided during intensive care. Studies have shown that manipulating the microbiome can prevent or modulate complications of critical illness in experimental models and preliminary clinical trials. This review aims to discuss general concepts about the microbiome, including mechanisms of modifying acute organ dysfunction.

Cyanobacterial harmful algal blooms (CyanoHABs) are longstanding aquatic hazards worldwide, of which the mechanism is not yet fully understood, i.e., the process in which cyanobacteria establish dominance over coexisting algae in the same eutrophic waters.

Here, we report the draft genome sequence of Bacillus cereus strain THSB-6-2, which was isolated from cyanobacterial blooms in Lake Taihu, China. The 5,496,658-bp genome assembly of Bacillus cereus consists of 28 contigs, with a GC content of 35% and with 5,587 protein-coding sequences and 58 RNA genes.

Long-standing cyanobacterial harmful algal blooms (CyanoHABs) are known to result from synergistic interaction between elevated nutrients and superior ecophysiology of cyanobacteria. However, it remains to be determined whether CyanoHABs are a result of positive selection by eutrophic waters. To address this, we conducted molecular evolutionary analyses on the genomes of 9 bloom-forming cyanobacteria, combined with pangenomics and metatranscriptomics.

Introduction: Savolitinib has been found to have encouraging antitumor activity and a favorable safety profile in Chinese patients with pulmonary sarcomatoid carcinoma and other NSCLCs with exon 14 skipping alterations ( ex14 positive) at the primary analysis of a phase 2 study. Here, we present the long-term efficacy and safety data of savolitinib, including subgroup analyses.

Methods: This multicenter, single-arm, open-label, phase 2 study in the People's Republic of China enrolled MET inhibitor-naive adults with locally advanced or metastatic ex14-positive NSCLC (NCT02897479).

Anaplastic lymphoma kinase () fusions have been identified in approximately 5% of non-small cell lung cancer (NSCLC) cases. ALK-tyrosine kinase inhibitors (TKIs) are the standard first-line treatment for patients with -positive (+) advanced NSCLC. Along with widespread use of next-generation sequencing (NGS) for the molecular diagnosis of lung cancer, an increasing number of fusion partners are being reported, with the majority being effective for ALK-TKIs.

Background: Recent studies have found that programmed death ligand 1 (PD-L1) might be involved in chemotherapy resistance in non-small cell lung cancer (NSCLC). Arsenic sulfide (As S ) has been recognized to have antitumor activities and enhance the cytotoxic effect of chemotherapy drugs. In this study, we aimed to verify the relationship between PD-L1 and cisplatin (DDP) resistance and identify whether As S could reverse DDP resistance through targeting PD-L1 in NSCLC.

Background: Programmed cell death 1 or programmed cell death ligand 1 inhibitor (PD-1/PD-L1 inhibitor) and docetaxel, as the standard second-line treatments of advanced non-small cell lung cancer (NSCLC) patients, have limited effects. There are few studies on whether docetaxel combined with PD-1/PD-L1 inhibitor can increase the efficacy and make patients better benefit. The aim of this study is to evaluate the efficacy and safety of docetaxel combined with PD-1/PD-L1 inhibitor for the second-line treatment of stage IV NSCLC patients.
