[PMID: 33800799 PMCID: PMC7961393 DOI: 10.3390/ijms22052654] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2021] [Revised: 02/25/2021] [Accepted: 03/02/2021] [Indexed: 02/06/2023] Open
Abstract
Liquid biopsies constitute a minimally invasive means of managing cancer patients, entailing early diagnosis, follow-up and prediction of response to therapy. Their use in the germ cell tumor field is invaluable since diagnostic tissue biopsies (which are invasive) are often not performed, and therefore only a presumptive diagnosis can be made, confirmed upon examination of the surgical specimen. Herein, we provide an overall review of the current liquid biopsy-based biomarkers of this disease, including the classical, routinely used serum tumor markers—the promising microRNAs rapidly approaching the introduction into clinical practice—but also cell-free DNA markers (including DNA methylation) and circulating tumor cells. Finally, and importantly, we also explore novel strategies and challenges for liquid biopsy markers and methodologies, providing a critical view of the future directions for liquid biopsy tests in this field, highlighting gaps and unanswered questions.

Abstract
Introduction: Liquid biopsy is an increasingly studied approach for optimal and minimally invasive diagnostics of malignant tumors. The aim of this review is to provide evidence and discuss the utility of liquid biopsy in the management of germ cell tumors (GCTs).Areas covered: Herein, we summarize the evidence on liquid biopsy in GCTs including serum tumor markers, circulating tumor cells, microRNA and cell-free DNA. The search of literature was conducted from Pubmed/Medline, ASCO-meeting library searching for terms 'liquid biopsy', 'germ cell tumors', 'circulating tumor cells', 'microRNA', 'cell-free DNA'. Obtained original studies were included. Reference lists of review articles and key original articles were searched for additional original studies. We included articles published between1990 and 2019.Expert opinion: Liquid biopsy is a minimally invasive tool using body fluids for diagnostic purposes in cancer. The established value of serum tumor markers may be already considered a liquid biopsy technique in diagnosis of GCTs. Possible near-future refinements in diagnosis of GCTs are emerging. Further information on diagnosis, prognosis and resistance is added with recently described microRNAs, circulating tumor cells and cell-free DNA. While great promise is shown, further large-scale validation is needed to incorporate these novel liquid biopsies into clinical practice.

Abstract
Analysis of circulating tumor cells from patients with different types of cancer is nowadays a fascinating new tool of research and their number is proven to be useful as a prognostic factor in metastatic breast, colon and prostate cancer patients. Studies are going beyond enumeration, exploring the circulating tumor cells to better understand the mechanisms of tumorigenesis, invasion and metastasis and their value for characterization, prognosis and tailoring of treatment. Few studies investigated the prognostic significance of circulating tumor cells in germ cell tumors. In this review, we examine the possible significance of the detection of circulating tumor cells in this setting.

Abstract
Imaging flow cytometry combines the statistical power and fluorescence sensitivity of standard flow cytometry with the spatial resolution and quantitative morphology of digital microscopy. The technique is a good fit for clinical applications by providing a convenient means for imaging and analyzing cells directly in bodily fluids. Examples are provided of the discrimination of cancerous from normal mammary epithelial cells and the high-throughput quantitation of fluorescence in situ hybridization (FISH) probes in human peripheral blood mononuclear cells. The FISH application will be enhanced further by the integration of extended depth-of-field imaging technology with the current optical system.

Abstract
The American Cancer Society has estimated that in 2003, there will be approximately 239,600 new cases of urologic cancer diagnosed and 54,600 urologic cancer-related deaths in the United States. To date, the majority of research and therapy design have focused on the microenvironment of the primary tumor site, as well as the microenvironment of the metastatic or secondary (target) tumor site. Little attention has been placed on the interactions of the circulating tumor cells and the microenvironment of the circulation (i.e., the third microenvironment). The purpose of this review is to present the methods for the detection and isolation of circulating tumor cells and to discuss the importance of circulating tumor cells in the biology and treatment of urologic cancers.
