International PPB/DICER1 Registry
Pleuropulmonary blastoma (PPB) is a rare malignant neoplasm of the lung presenting in early childhood. Type I PPB is a purely cystic lesion, Type II is a partially cystic, partially solid tumor, Type III is a completely solid tumor. Treatment of children with PPB is at the discretion of the …
Collecting Blood Samples From Patients With and Without Cancer to Evaluate Tests for Early Cancer Detection
This study collects blood and tissue samples from patients with cancer and without cancer to evaluate tests for early cancer detection. Collecting and storing samples of blood and tissue from patients with and without cancer to study in the laboratory may help researchers develop tests for the early detection of …
Transcriptional Map of Ovarian Cancer at the Single Cell Level
In 2020, epithelial ovarian cancer (EOC) accounts for 313,959 new cases and 207,252 deaths worldwide. The standardized 5-year net survival of a woman with EOC is 44% for cases diagnosed between 2005-2010. This is because 2 out of 3 cancers are found at an advanced stage with invasion beyond the …
Study on the Dynamic Changes of Metabolic Biomarkers and Their Prognostic Relationship in Ovarian Cancer
Ovarian cancer is a highly lethal gynecological malignancy, often diagnosed at an advanced stage, with high rates of recurrence within 1-2 years after frontline treatment. Current guidelines recommend monitoring tumor markers CA125 and HE4 for disease progression, but these markers may not detect recurrence or disease progression when their levels …
Doppler Ultrasound and CT Versus Laparoscopy in Assessment of Ovarian Malignancy
The aim of this study is to assess validation of ultrasound (± Doppler) parameters in the diagnosis of suspicious ovarian malignant tumors and laparoscopic assessment of these findings according to Fagotti score evaluation of suspicious malignant tumors
Systems Oncology Approach to Optimize Ovarian Cancer Treatment
The overall aim is to identify effective therapeutic strategies to ovarian cancer (OC) using serial tumor, ascites and blood samples, and carry out state-of-the-art sequencing approaches, functional assays and associated bioinformatics to understand mechanisms behind chemoresistance in OC and identify new treatment options for OC patients. In this observational trial, …
Evaluation of Prognostic Monitoring for Women Who Have Completed Standard Treatment for Ovarian Cancer
The relationship between immune inflammation-related protein complexes inblood and recurrence or metastasis of ovarian cancer will be studied
Laboratory Study of Cancer & Immune Cells in Ascites Fluid of Ovarian Cancer Patients to Test Alternative Therapies
Ascites samples from women undergoing surgery for ovarian cancer will be collected for use in translational research.
Prognostic Value of MRD Detection in CA125 Non-sensitive Ovarian Cancer Patients
Ovarian cancer ranks third in the incidence of gynecologic malignancies, while mortality ranks first. The tumor marker CA125 is the most concerned tumor marker in the clinical monitoring prognosis of ovarian cancer, and an elevated CA125 indicates a later stage and a worse prognosis. However about 20% of patients with …
Prospective Cohort Study for Validation of Predictive Immune Biomarkers of Response to PAPR Inhibitors
Increasing number of ovarian cancer patients are receiving PARP inhibitor as maintenance therapy. Predictive factors to PARP inhibitor other than BRCA mutation or HRD status are unknown. Previous study, we analyzed the dynamic immunological changes in peripheral T cells during PARP inhibitor maintenance therapy and found predictive biomarkers. The purpose …
