Prognostic value of extracellular vesicles in colorectal cancer: a systematic review and meta-analysis.
Objective: Extracellular vesicles (EVs) are prognostic factors in colorectal cancer (CRC). This study aims to evaluate the prognostic value of EVs CRC.
Methods: Clinical studies that directly investigated the association between EVs in different kinds of body fluids of CRC patients and patient prognosis were included by searching the PubMed, Web of Science, ClinicalTrials, and CENTRAL databases. The associations between single biomarkers, molecular panels, and EVs count with overall survival (OS), disease-free survival (DFS), and recurrence-free survival (RFS) were analyzed. Heterogeneity was assessed using the I2 statistic, with a random-effects model applied when I2 > 30% and a fixed-effects model when I2 ≤ 30%.
Results: A total of 56 studies involving 5,985 patients were included. All included studies detected EVs in blood. Univariate analysis revealed an association between EVs single-biomarkers and OS (pHR = 2.07, 95% CI: 1.73-2.73) and DFS (pHR = 2.20, 95% CI: 1.46-2.79). Additionally, univariate analysis revealed an association between molecular-panels in EVs and OS (pHR = 3.67, 95% CI: 2.51-5.36) and RFS (pHR = 3.97, 95% CI: 1.57-10.08). Moreover, an association was observed between a EVs count and OS (pHR = 1.87, 95% CI: 1.40-2.49). On the basis of the results of the meta-regression and subgroup analyses, the subgroups of EVs and the disease stage of CRC patients are key factors contributing to the heterogeneity in the associations between EVs single-biomarkers and OS.
Conclusion: This study provides compelling evidence that EVs from blood hold prognostic value in CRC.
期刊介绍：
Clinical and Translational Oncology is an international journal devoted to fostering interaction between experimental and clinical oncology. It covers all aspects of research on cancer, from the more basic discoveries dealing with both cell and molecular biology of tumour cells, to the most advanced clinical assays of conventional and new drugs. In addition, the journal has a strong commitment to facilitating the transfer of knowledge from the basic laboratory to the clinical practice, with the publication of educational series devoted to closing the gap between molecular and clinical oncologists. Molecular biology of tumours, identification of new targets for cancer therapy, and new technologies for research and treatment of cancer are the major themes covered by the educational series. Full research articles on a broad spectrum of subjects, including the molecular and cellular bases of disease, aetiology, pathophysiology, pathology, epidemiology, clinical features, and the diagnosis, prognosis and treatment of cancer, will be considered for publication.
