Application of FAPI and FDG PET Imaging in Patients With Different Types of Cancer

Cancer associated fibroblasts (CAFs) can promote tumor cell proliferation, migration, invasion, and angiogenesis through immunosuppressive effects and the production of mediators, thereby promoting tumor growth and progression. The characteristic of CAFs is high expression of fibroblast activation protein (FAP). In approximately 90% of epithelial derived tumors, FAP is highly overexpressed on the membrane of CAFs. Contrary to CAFs, FAP expression is lower or absent in normal tissues. Therefore, FAP inhibitors (FAPI) targeting FAP can overcome the limitations of 18F-2-fluoro.2-deoxy-D-glucose fluorodeoxyglucose(18F-FDG) PET imaging. But like 18F-FDG, wound healing, fibrosis, and inflammation can also uptake FAPI.. Therefore, a comparison of the performance of 18F-FDG and 18F-FAPI PET imaging in diagnosing primary and metastatic lesions of various types of cancer is conducted to evaluate the potential value of these new radiopharmaceuticals as effective alternatives to 18F-FDG, highlighting their advantages and limitations.

Assessment of Hypoxia Before Radioembolization Treatment With 18F-FMISO PET

Hypoxia is a known factor for resistance to radiotherapy in tumors. Response to transarterial radioembolization is known to be variable between different patients even if the same dose of radiation was delivered. In this study the investigators aim to quantify the hypoxia in the primary and secondary tumors of liver with 18F-FMISO PET before radioembolization and to prove any effect of the hypoxia, if present, on the dose that should be delivered to tumor to ensure treatment response.

Clinical Evaluation of 18F-FAPI-RGD PET/CT for Imaging of Fibroblast Activation Protein and Integrin avb3 in Various Tumor Types

The aim of this study is to evaluate, in patients with various types of tumor, the radiotracer uptake and clinical feasibility of 18F-FAPI-RGD PET/CT compared with those of 18F-FDG PET/CT.

For patients for whom tissue diagnosis is not applicable, clinical and radiographic follow-up data will be used as the reference standard to validate the PET/CT findings.

68Ga-FAP-RGD PET/CT : Dosimetry and Preliminary Clinical Translational Studies in Cancer Patients

Fibroblast activation protein (FAP) is highly expressed in the stroma of a variety of human cancers and is therefore considered promising for guiding targeted therapy. The recent development of quinoline-based PET tracers that act as FAP inhibitors (FAPIs) demonstrated promising results preclinically and already in a few clinical cases. Integrin αvβ3 is restrictedly expressed on angiogenic blood vessels and tumour cells. It plays a key role in angiogenesis for tumour growth and metastasis. RGD peptide can specifically recognise the integrin αvβ3, which serves as targeted molecular for anti-angiogenesis strategies. 68Ga-FAP-RGD is a novel dual targeting tracers. The present study aimed to evaluate the biodistribution, pharmacokinetics, and dosimetry of 68Ga-FAP-RGD, and performed a head-to-head comparison with 68Ga-FAPI-02 or 18F-FDG PET/CT scans in patients with various cancers.

NCT05034146

The Diagnostic Efficiency of 68Ga-FAPI PET/CT in Malignant Tumors

Fibroblast-activation protein (FAP) is a type Ⅱ transmembrane serine protease and is overexpressed in cancer-associated fibroblasts (CAFs). CAFs are the predominant component in the stroma of epithelial neoplasms. FAP can be detected in various of malignant neoplasms and is associated to tumor cell migration, invasion, and angiogenesis. Recently, a novel molecular probe, gallium 68-labelled FAP inhibitor (68Ga-FAPI), has been developed and used for visualization of tumor stroma by targeting FAP. Recent studies show favorable diagnosis efficiency in a variety of tumors, especially in gastrointestinal cancer, but the previous studies were all small-sample data or case reports. Therefore, further large-size research is necessary to confirm the advantages of 68Ga-FAPI in various of malignant tumors.

A Phase I Study Evaluating the Safety and Imaging Characteristics of 18F-LY3546117 Injection in Subjects Who Are Undergoing Treatment With Immune Checkpoint Inhibitors

Immuno-Oncology (IO) therapies have revolutionized cancer therapy and are becoming the standard of care for many cancers. Monitoring how well IO therapies work against cancer is difficult due to the complexity of the immune system and the fact that an immune response may initially increase, rather than decrease, the size of a tumor. An early response marker would be beneficial to determine which patients should remain on a given treatment or combination of treatments, and which patients should seek other treatment options. 18F-LY3546117 is a radiolabeled tracer that binds to a specific protein (Granzyme B) that is found in the human immune system and is thought to trigger programmed cell death. It is thought that imaging Granzyme B activity in tumors and elsewhere in the body using a Positron Emission Tomography (PET) scan will allow doctors to monitor the progress of IO therapy.

The Brain Metabolic Change in Chronic Cancer Pain Patient: FDG PET Image Study

Cancer pain deteriorated in quality of life and related with numerous psychosocial problems. Over the one third of cancer patient suffered from moderate to severe cancer pain, even under adequate pain management. The 18F-fluoro-2-deoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) images can provide quantitative results in clinical oncology. As a functional neuroimaging, the PET evidently provided anatomical activated regions, size, and spatial extent information. In this study, we use FDG-PET to investigate changes concerning the glucose metabolism in the brain with or without cancer pain. Therefore, we may provide useful information to treatment target in cancer pain patients.

A Pilot Prospective Study of the RefleXion [18F]- FDG PET-CT Subsystem Imaging Performance in Patients With Various Malignancies

This clinical trial examines RefleXion Medical Radiotherapy System (RMRS) imaging to the standard of care (SOC) fludeoxyglucose F-18 ([18F]-FDG)- positron emission tomography (PET)-computed tomography (CT) imaging in patients with various cancers (malignancies). PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of tracer, in the case of this research, [18F]-FDG. Because some cancers take up [18F]-FDG, cancer cells can be seen with PET. CT utilizes x-rays that traverse body from the outside. CT images provide an exact outline of organs and potential inflammatory tissue where it occurs in patient's body. The RefleXion system is designed to facilitate delivery of biology-guided radiotherapy (BgRT). The RMRS uses PET emissions to guide radiotherapy delivery in real-time and has been studied for use with FDG (which is an agent used in standard PET-CT scans that targets glucose). Information gathered from this study may help researchers to improve PET-CT imaging on the RefleXion system. This information will be used in the future to improve planning and delivery of radiotherapy that will target (in real time) the signal released from the [18F]-FDG-PET-CT tracer. Comparing the imaging from the standard of care [18F]-FDG-PET-CT with the [18F]-FDG imaging from RMRS may help improve the quality of the imaging captured and determine if imaging can be done on the RMRS at the same time as planning for radiation therapy, which would reduce the number of scans needed to plan for radiation for cancer.

Interest of the Early Dynamic F-DOPA PET Examination for Differential Diagnosis Between Recurrence and Radionecrosis of Brain Metastasis

Contrast-enhanced magnetic resonance imaging is the most widely used examination for detecting the presence of brain metastasis. Functional sequences such as perfusion weighted imaging makes it possible to differentiate tumor recurrence from cerebral radionecrosis. However, this imaging technique may exhibit limitations, especially for brain lesions consisting of a mixture of necrotic tissue and tumor progression or depending on the location of the lesion in the brain.
