The Effectiveness of Liquid Biopsy in Differential Diagnosis and Early Screening of Epithelial Ovarian Cancer
The Effectiveness of Liquid Biopsy in Differential Diagnosis of Benign and Malignant Ovarian Tumors and Early Screening of Epithelial Ovarian Cancer, and the Exploration of Invasive Mechanisms of Epithelial Ovarian Cancer
At present, there is a lack of effective screening methods. It is urgent to explore new non-invasive detection methods for early diagnosis of epithelial ovarian cancer and non-invasive differentiation methods for benign and malignant ovarian tumors.
Liquid biopsy technology has great potential for early screening of tumors. The fragmentation patterns of cfDNA fragments in plasma and the uneven coverage of the genome can indirectly reflect the state of gene expression regulation in vivo. Its characteristics mainly include copy number variation (CNV), Nucleosome footprint, fragment length and motif.
The number of proteins in a proteome can sometimes exceed the number of genomes. It includes "structural Proteomics" and "functional Proteomics". At present, research has explored the use of urinary protein biomarkers for early diagnosis of gastric cancer. "Deep Visual Proteomics (DVP)" reveals the mechanism driving tumor evolution and new therapeutic targets for tumors.
Using the currently mature low depth WGS sequencing technology, this study aims to explore its clinical application in the differentiation and early screening of epithelial ovarian cancer, as well as monitoring the course of epithelial ovarian cancer, including the detection of minimal residual lesions (MRD) and monitoring of recurrence (MOR). This study also explores the role of urine proteomics in the differentiation of benign and malignant ovarian tumors, early screening and invasiveness of epithelial ovarian cancer, and monitoring the course of epithelial ovarian cancer.

Detailed Description
At present, there is a lack of effective screening methods. Numerous studies and practices have shown that tumor screening and early diagnosis and treatment can effectively prolong the overall survival period of cancer patients and reduce the economic burden of the disease. The traditional early screening methods for tumors in clinical practice, including imaging screening, endoscopic screening, and tumor marker screening, generally have defects such as strong invasiveness, significant discomfort during the screening process, low accuracy (false negative, false positive), and poor compliance. Therefore, it is urgent to explore new non-invasive detection methods for early diagnosis of epithelial ovarian cancer and non-invasive differentiation methods for benign and malignant ovarian tumors.
Liquid biopsy technology, as a non-invasive new detection technology, has great potential for early screening of tumors. CfDNA is an important marker for liquid biopsy and has been widely used in non-invasive prenatal examinations and cancer liquid biopsy research. The fragmentation patterns of cfDNA fragments in plasma and the uneven coverage of the genome can indirectly reflect the state of gene expression regulation in vivo. Its characteristics mainly include copy number variation (CNV), Nucleosome footprint, fragment length and motif.
Proteome changes with different tissue and even environmental states. During transcription, a gene can be spliced in multiple mRNA forms, and a proteome is not a direct product of a genome. The number of proteins in a proteome can sometimes exceed the number of genomes. It includes "structural Proteomics" and "functional Proteomics". The former is mainly the study of protein expression models, including protein amino acid sequence, analysis and spatial structure analysis, type analysis and quantity determination; The latter mainly focuses on the study of protein functional patterns, including protein function and protein-protein interactions. At present, research has explored the use of urinary protein biomarkers for early diagnosis of gastric cancer. "Deep Visual Proteomics (DVP)" reveals the mechanism driving tumor evolution and new therapeutic targets for tumors.
There is ample evidence to support the diagnostic value of fragment omics research in tumors. Using the currently mature low depth WGS sequencing technology, this study aims to explore its clinical application in the differentiation and early screening of epithelial ovarian cancer, as well as monitoring the course of epithelial ovarian cancer, including the detection of minimal residual lesions (MRD) and monitoring of recurrence (MOR). In addition, there is currently no research on the use of urine proteomics in the differentiation and early screening of ovarian cancer. This study also explores the role of urine proteomics in the differentiation of benign and malignant ovarian tumors, early screening and invasiveness of epithelial ovarian cancer, and monitoring the course of epithelial ovarian cancer.

The fragmentation patterns of cfDNA fragments in plasma and the uneven coverage of the genome can indirectly reflect the state of gene expression regulation in vivo.
Its characteristics mainly include copy number variation (CNV), Nucleosome footprint, fragment length and motif.
Fragomics relies on WGS (Whole Genome Sequencing), and the target covers the whole Genomics level.
Thus, the cfDNA Fragmentomics testing can help differentiation and early diagnosis.
