Genotyping of tumor tissues to assess and V600E mutations enables us to select optimal molecularly targeted therapies when considering treatment strategies for patients with metastatic colorectal cancer. Tissue-based genetic testing is limited by the difficulty of performing repeated tests, due to the invasive nature of tissue biopsy, and by tumor heterogeneity, which can limit the usefulness of the information it yields. Liquid biopsy, represented by circulating tumor DNA (ctDNA), has attracted attention as a novel method for detecting genetic alterations. Liquid biopsies are more convenient and much less invasive than tissue biopsies and are useful for obtaining comprehensive genomic information on primary and metastatic tumors. Assessing ctDNA can help track genomic evolution and the status of alterations in genes such as , which are sometimes altered following chemotherapy. In this review, we discuss the potential clinical applications of ctDNA, summarize clinical trials focusing on , and present the future prospects of ctDNA analysis that could change daily clinical practice.

Background: Malignant brain tumors are among the most lethal cancers. Recent studies emphasized the crucial involvement of the immune system, especially T cells, in driving tumor progression and influencing patient outcomes. The emerging field of immunometabolism has shown that metabolic pathways play a pivotal role in regulating immune responses within the tumor microenvironment.

The analysis of circulating tumour DNA (ctDNA) through minimally invasive liquid biopsies is promising for early multi-cancer detection and monitoring minimal residual disease. Most existing methods focus on targeted deep sequencing, but few integrate multiple data modalities. Here, we develop a methodology for ctDNA detection using deep (80x) whole-genome TET-Assisted Pyridine Borane Sequencing (TAPS), a less destructive approach than bisulphite sequencing, which permits the simultaneous analysis of genomic and methylomic data.

Objective: To explore the impact of mild hypercapnia or normocapnia on the prognosis of patients after the return of spontaneous circulation (ROSC) following cardiac arrest (CA).
Methods: This systematic review and meta-analysis followed the guidelines in the PROSPERO report. Information was retrieved in PubMed, Cochrane Library, Embase, and Web of Science to collect all publications in English from January 1, 2000, to March 1, 2024, involving post-CA with mild hypercapnia.

Capturing circulating tumor cells (CTCs) in vivo from the bloodstream lessens tumor metastasis and recurrence risks. However, the absence of CTC receptors due to epithelial-mesenchymal transition (EMT), the limited binding capacity of a single ligand, and the complexity of the blood flow environment significantly reduce the efficiency of CTC capture in vivo. Herein, a multivalent ligand-decorated microsphere enrichment system (MLMES) is crafted that incorporates a capture column replete with an immunosorbent that precisely recognizes and binds the stably expressed cluster of differentiation 44 (CD44) and glucose transporter protein 1 (GLUT1) receptors present on the exterior of CTCs.

Objective: Several observational studies have identified an association between plasma proteins and hepatocellular carcinoma (HCC). This study aimed to explore the potential causal relationship between the circulating protein-to-protein ratio and the morbidity risk of HCC.
Methods: Genetic association data for circulating plasma proteins and 2821 protein-to-protein ratios were sourced from the UKB PPP and Suhre's study.
