A Study to Analyze Data on Metastatic Ovarian Cancer Using Multi-omics
Ovarian CancerAs one of the most common malignant tumors in women, the incidence of ovarian cancer is expected to increase year by year. Due to its lack of typical symptoms and effective screening methods, and the characteristics of implantation and distant metastasis, more than 70% of ovarian cancers were in the metastatic stage at the time of diagnosis. In this study, the investigators will collect large samples of tissue from patients with ovarian cancer, conduct multi-omics studies, and mapped the characteristic maps of the genome and transcriptome of patients with metastatic ovarian cancer, and explore the molecular mechanisms that can be used as new targets for the treatment of ovarian cancer. Besides, the investigators will design and establish a database of metastatic ovarian cancer, integrate multiple omics, imaging, pathology, and clinical information to study their potential relevance, and analyze the relationship between various omics, imaging, pathology, and prognosis, establish ovaries Cancer prediction model.
miRNAs in High Grade Serous Ovarian Cancer
High Grade Serous Ovarian CancerHigh grade serous ovarian cancer represents the gynecological malignancy with the highest incidence of mortality. Decision-making tools are currently limited to the use of standard imaging modalities and analysis of serum biomarkers, such as CA 125, which often have low specificity and sensitivity. Recently, a growing research interest has been aimed at so-called circulating microRNAs (miRNAs). Indeed, it has been observed that miRNAs are abundantly present in all biological fluids and play the key role of messengers in intercellular communication. Cancer cells have a rapid turnover which results in a continuous release of nucleic acids and vesicles derived from the tumor itself, such as the tumor cells themselves that separate from the tumor mass to enter the bloodstream. Given their important role as modulators of gene expression, in order to preserve their integrity, miRNAs are encapsulated in specific vesicles, in order to prevent their degradation by the enzymes present in biological fluids. In this context, the chance of monitoring the expression levels of specific miRNAs represents a very interesting option both for an early diagnosis and for monitoring the clinical response to pharmacological treatment. Currently, there are no non-invasive approaches to monitor the clinical outcome in real time, while the identification of circulating biomarkers would allow prompt intervention, possibly modifying the pharmacological management in case of progression.

Effect of Sodium Thiosulfate on Nephrotoxicity of Cisplatin Intraperitoneal Heat-perfusion Chemotherapy...
Epithelial Ovarian CancerAcute Kidney Injury Due to Circulatory FailureOvarian cancer is the most lethal malignancy of the female genital tract. Cytoreductive surgery combined with chemotherapy is the primary treatment for ovarian cancer, and radical tumor resection is an important means to improve the prognosis. However, even after complete tumor resection, 75% of patients with ovarian cancer still recur within 3 years after the initial treatment and eventually die from recurrence. In ovarian cancer, the lesions are located primarily in the peritoneal cavity. High-grade evidence demonstrates that the use of intraperitoneal hyperthermic chemotherapy (HIPEC) with cisplatin after cytoreductive surgery significantly improves the outcome in some patients with ovarian cancer. Currently, this is the only non-pharmacologic treatment that reduces both the risk of recurrence and death from ovarian cancer with a multi treatment. However, HIPEC with cisplatin can lead to acute kidney injury, and a serious complication that can seriously affect the short and long-term prognosis of patients. Sodium thiosulfate has previously been reported to reduce the incidence of acute kidney injury after HIPEC with cisplatin, but this finding has not been confirmed in a high-level study. Therefore, we propose a multi-center, prospective, open-label, randomized, controlled trial including 110 patients with ovarian cancer who received HIPEC with cisplatin, to evaluate whether sodium thiosulfate combined with hydration (55 patients in the trial group) can reduce the incidence of acute kidney injury after HIPEC with cisplatin compared with hydration alone (55 patients in the control group), and to provide high-level evidence for the rationale of using sodium thiosulfate for nephrotoxicity relief in cisplatin HIPEC.
ctDNA Methylation for Detecting Ovarian Cancer
Epithelial Ovarian CancerCirculating Tumor DNA7 moreOvarian cancer is one of the most dangerous and leading gynecological cancer, with significant cancer-related mortality among women. However, current detection methods are still limited, with approximately 70% of patients with high-grade serous ovarian cancer often being advanced at the initial diagnosis and more than 80% with intraperitoneal spread. The five-year survival rate for late detection is only 29%; on the contrary, if detected early, the five-year survival rate can reach 92%. Therefore, early diagnosis and detection are essential in diagnosing and treating ovarian cancer. Liquid biopsy has attracted widespread attention because of its non-invasive, real-time, and dynamic characteristics. Cell-free DNA in plasma can identify a small tumor burden well and reflect the clinical cancer information of cells.The role of hypermethylation in developing malignant tumors has received increasing attention. Methylation is one of epigenetics and plays a vital role in the occurrence and development of tumors. According to previous research basis of the researchers, it has been found that CDO1 and HOXA9 genes show hypermethylation in ovarian cancer, and they are considered one of the biomarkers for detection. Therefore, this study will further explore the detection of CDO1 and HOXA9 methylation levels based on cell-free DNA in blood and compared with ovarian pathology results; the application of methylation detection technology in ovarian cancer/precancerous lesions will further explore the application value of non-invasive diagnosis and prognostic follow-up.This study will involve three centers and is expected to enroll more than 1,400 clinical subjects, further examine the consistency of methylation detection kits with the histopathological examination, ROMA index, and Sanger sequencing results, and obtain sensitivity and specificity technical performance parameters.
