Evaluation of 68Ga-FAPI-46 and 18F-FDG PET/CT Imaging for Detecting Recurrent Tumor Lesions in Patients of Ovarian Cancer With CA125 Elevation From Complete Response After Therapy
Ovarian cancer is the eighth most common cancer worldwide in females and usually diagnosed at an advanced stage. Serum cancer antigen 125 (CA125) is widely used in ovarian cancer. An elevation in CA125 levels can precede a clinically apparent recurrence by 3 to 6 months and 18F-FDG PET/CT can modify management in approximately half of these patients. However. 18F-FDG PET/CT may yield false negative results. 68Ga-FAPI-46 PET/CT shows potential here. This study is to assess the diagnostic performances of 68Ga-FAPI-46 and 18F-FDG PET/CT for ovarian cancer recurrence in patients with CA125 elevation from complete response after therapy.

Integration of Multiple Data Levels to Improve Diagnosis, Predict Treatment Response and Suggest Targets to Overcome Therapy Resistance in High-grade Serous Ovarian Cancer
This prospective, observational trial focuses on revealing major mechanisms causing chemoresistance in HGSOG patients and derive personalized treatment regimens for chemotherapy resistant HGSOC patients. The investigators recruit newly diagnosed advanced stage HGSOC patients who are then thoroughly followed during their cancer treatment. Longitudinal sampling includes digitalized H&E stained histology slides mainly collected during routine diagnostics, fresh tumor & ascites samples for next-generation sequencing/proteomics (WGS, RNA-seq, DNA-methylation, ChIP-seq, mass cytometry, etc.) and ex vivo experiments, plasma samples for circulating tumor DNA (ctDNA) analyses. Broad range of clinical parameters such as laboratory and radiologic parameters (e.g., FDG PET/CT), given cancer treatments and their outcomes are collected.

PET Biodistribution Study of 68Ga-FAPI-46 in Patients With Different Malignancies: An Exploratory Biodistribution Study With Histopathology Validation
This exploratory study investigates how an imaging technique called 68Ga-FAPi-46 PET/CT can determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulates in normal and cancer tissues in patients with cancer. Because some cancers take up 68Ga-FAPi-46 it can be seen with PET. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors (cancer associated fibroblasts). The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers.

Phase I Pilot Study of Biodistribution, Metabolism and Excretion of Novel Radiotracer [18F]Fluorthanatrace (FTT) by PET/CT
Up to 35 evaluable women with known or suspected epithelial ovarian, fallopian tube, or primary peritoneal cancer will participate in two different imaging cohorts. The Biodistribution cohort will include up to 10 patients and the Dynamic cohort will include up to 20 patients. Human dosimetry will be calculated from the Biodistribution cohort. The Dynamic cohort date will evaluate preliminary information on uptake of [18F]FTT in gynecological cancer and compare with PARP-1 activity in tissue.

PSMA Positron Emission Tomography (PET) and Magnetic Resonance (MR) Imaging in Gynecological Cancers
The goal of this research is to determine the accuracy of PSMA positron emission tomography (PET) and multi-parametric magnetic resonance (MR) imaging to detect the presence of gynecological cancer cells in the body.

A Study of the Drug I131-Omburtamab in People With Desmoplastic Small Round Cell Tumors and Other Solid Tumors in the Peritoneum
The purpose of this study is to test any good and bad effects of the study drug 131I-omburtamab. 131I-omburtamab could prevent the cancer from returning, or delay the cancer from getting worse, but it could also cause side effects. Researchers hope to learn more about how 131I-omburtamab works in the body, and how effective it is in treating cancer. 131I-Omburtamab is not approved by the FDA to treat DSRCT or other cancers of the peritoneum.

A Prospective Cohort Study of 68ga-FAPI-pet-ct Versus FDG-pet-ct for Ovarian Cancer
A study to discuss the advantage of Fapi PET- CT in the initial diagnosis staging and lesion determination of ovarian cancer,whether it can be a evaluation strategy as an R0 evaluation tool or a prediction tool of chemotherapy response and evaluation of prognosis.

Evaluation of the Interest of PET/CT at 18F-FDG in the Post-therapeutic Management of Cervical Cancer at an Advanced Stage. Multicenter Prospective Observational Study
A lot of studies have demonstrated the prognostic value of post therapy 18F-FDG PET/CT in the management of uterine cervical cancer. Post therapy 18F-FDG PET/CT is usually requested by a lot of clinicians. Whereas 18F-FDG PET/CT is useful for prognosis in the follow-up, data are yet insufficient to clearly establish a formal recommendation. This prospective multicenter observational study will evaluate the interest of post therapy 18F-FDG PET/CT in clinical management (within 2 months of treatment) in patients with cervical cancer at an advanced stage.

Intratreatment FDG-PET During Radiation Therapy for Gynecologic and Gastrointestinal Cancers ( Adaptive PET II)
This study expands on protocol (NCT01908504"PET adaptive RT") designed to evaluate the utility of adaptive PET-CT planning for radiation therapy (RT). Radiation therapy is used in many malignant diseases as a curative treatment modality. However, critical normal tissue is often in close approximation to disease, and portions of such tissue must receive high doses of radiation for appropriate treatment. Positron Emission Tomography (PET) adapted radiation therapy, as defined in the current protocol, may allow for a means of determining the eventual response to therapy, at a time point when adaptation of treatment plan may be possible to improve outcomes. This protocol will build upon the findings the previous protocol (NCT01908504 "PET adaptive RT") that evaluated the utility of intra-treatment PET imaging in multiple types of cancers. The current focus will be more specific to certain types of gastrointestinal and gynecologic cancers treated with RT, identified from the prior study to warrant further research.

PET Imaging of Tumors in Pancreas, Bile Ducts, Stomach and Ovaries by a Novel Tracer, 68Ga-FAPI-46 = Fibroblast Activation Protein Inhibitor
Cancers of the pancreas, bile ducts, stomach and ovaries are dismal diseases with most patients being diagnosed in advanced stages leading to a bad prognosis. These cancers can be difficult to diagnose and sometimes impossible to differentiate from underlying benign conditions. Establishing the correct diagnosis of primary cancer lesions and possible spread to other organs in time is pivotal for choosing the right therapy. Routinely applied staging procedures are however not always reliable. The main aim in this study is to evaluate the diagnostic accuracy of PET/CT with a novel radiotracer, FAPI, in the primary diagnosis of cancers in the pancreas, stomach and bile ducts as well as in patients with primary and recurrent epithelial ovarian cancer (EOC).

Phase 1 2 Study of Individualized Bone Marrow Sparing Image Guided Radiotherapy Incorporating Novel Use of Granulocyte Colony Stimulating Factor and FDG PET Imaging
This is a research study using Granulocyte Colony Stimulating Factor (GCSF) as a bone marrow stimulating agent for imaging to guide radiation treatment planning. G-CSF is a type of growth factor. Growth factors are proteins made in the body. G-CSF is a type of growth factor that makes the bone marrow produce white blood cells to reduce the risk of infection after some types of cancer treatment.
