Exosomal RNA biomarkers in pancreatic ductal adenocarcinoma: Systematic review and meta-analysis.
Pancreatic cancer is a highly lethal malignancy, ranking tenth in incidence among all cancers and standing as the fourth leading cause of cancer-related mortality worldwide. This systematic review and meta-analysis evaluated the diagnostic performance of exosomal biomarkers for detecting pancreatic ductal adenocarcinoma (PDAC). A total of 1,666 records were identified through comprehensive searches in Scopus, Web of Science, and PubMed. After removing duplicates and screening titles, abstracts, and full texts, 15 studies comprising 1,961 individuals (971 PDAC patients and 990 controls) were included. The quality of studies was assessed using the QUADAS-2 tool, revealing potential biases mainly in patient selection and index test domains. Three biomarker categories were analyzed: exosomal microRNAs (exomiRs), cancer antigen 19-9 (CA 19-9), and glypican-1 (GPC1). ExomiRs demonstrated the highest pooled sensitivity (0.86; 95 % CI: 0.80-0.90) and lowest negative likelihood ratio (0.16; 95 % CI: 0.11-0.24), while CA 19-9 showed the highest specificity (0.91; 95 % CI: 0.84-0.95) and positive likelihood ratio (8.5; 95 % CI: 4.4-16.4). ExomiRs also had the highest diagnostic odds ratio (DOR = 35.4; 95 % CI: 18.7-67.0) and area under the SROC curve (AUC = 0.92; 95 % CI: 0.89-0.94), indicating superior diagnostic performance compared to CA 19-9 and GPC1 (AUC = 0.88 and 0.78, respectively). GPC1 consistently showed lower diagnostic metrics across all analyses. Deeks' funnel plot suggested no publication bias for CA 19-9 and GPC1, but indicated potential bias for exomiRs (P = 0.01). Overall, exomiRs appear to be promising non-invasive biomarkers for the early detection of PDAC, outperforming traditional and other exosome-based markers in diagnostic accuracy.
期刊介绍：
The Official Journal of the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC)
Clinica Chimica Acta is a high-quality journal which publishes original Research Communications in the field of clinical chemistry and laboratory medicine, defined as the diagnostic application of chemistry, biochemistry, immunochemistry, biochemical aspects of hematology, toxicology, and molecular biology to the study of human disease in body fluids and cells.
The objective of the journal is to publish novel information leading to a better understanding of biological mechanisms of human diseases, their prevention, diagnosis, and patient management. Reports of an applied clinical character are also welcome. Papers concerned with normal metabolic processes or with constituents of normal cells or body fluids, such as reports of experimental or clinical studies in animals, are only considered when they are clearly and directly relevant to human disease. Evaluation of commercial products have a low priority for publication, unless they are novel or represent a technological breakthrough. Studies dealing with effects of drugs and natural products and studies dealing with the redox status in various diseases are not within the journal''s scope. Development and evaluation of novel analytical methodologies where applicable to diagnostic clinical chemistry and laboratory medicine, including point-of-care testing, and topics on laboratory management and informatics will also be considered. Studies focused on emerging diagnostic technologies and (big) data analysis procedures including digitalization, mobile Health, and artificial Intelligence applied to Laboratory Medicine are also of interest.
