Circulating tumor cells (CTCs) are released from primary tumors and transported through the body via blood or lymphatic vessels before settling to form micrometastases under suitable conditions. Accordingly, several studies have identified CTCs as a negative prognostic factor for survival in many types of cancer. CTCs also reflect the current heterogeneity and genetic and biological state of tumors; so, their study can provide valuable insights into tumor progression, cell senescence, and cancer dormancy. Diverse methods with differing specificity, utility, costs, and sensitivity have been developed for isolating and characterizing CTCs. Additionally, novel techniques with the potential to overcome the limitations of existing ones are being developed. This primary literature review describes the current and emerging methods for enriching, detecting, isolating, and characterizing CTCs.

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.
