  • Introduction of Y90-PET-CT Post Radioembolisation Therapy Scans

    The study will be conducted on patients with liver cancer and/or liver metastasis, referred to as 90Y-microspheres radiation therapy or Y-90 radioembolisation. There will be 10 patients recruited. No further radioisotope administration will be performed (please refer to section 7 for full eligibility criteria). Primary Outcome - Introduce and optimise a Y90-PET-CT protocol post-therapy scan for patients undergoing 90Y-radioembolisation treatment. The Y90-PET-CT scan will be used primarily to confirm the radiotracer delivery to the target lesions. A Y90-PET-CT scan is believed to provide improved quality images compared to a Y90-bremsstrahlung-SPECT scan; hence, more accurate information on the success/failure of the therapy is expected to be obtained when using Y90-PET-CT images. Secondary Outcomes - Introduce in the department post-therapy dosimetry for Y90-microspheres radioembolisation using the optimised 90Y-PET-CT images obtained from the primary objective. This work will be done following published guidelines for post-therapy dosimetry and using pre-existing and bespoke commercial software applications that perform this task. The investigators expect the images resulting from 90Y-PET-CT will provide better information about the success or not of the infusion of the 90Y-microspheres into the target areas. 90Y-PET-CT will, in turn, provide a better understanding of post-therapy scans in our department, better management of 90Y-radioembolization patients and the development of improved radioembolization treatment-planning models in the future.

  • The Radium-select Study

    Study design: The investigators will conduct a prospective clinical study in which patients with mCRPC and bone-only disease according to ceCT and bone scan will receive standard-of-care treatment with Radium-223. In addition to standard-of-care systemic treatment, each patient will undergo an additional 68Ga-PSMA-PET/CT scan at baseline and will be followed throughout the treatment with patient reported outcome measure (PROM) questionnaires (Kaiku application) and blood sampling for circulating tumor DNA (ctDNA) analysis. The treating physicians will be blinded to the result of the baseline 68Ga-PSMA-PET/CT scan. Each patient will receive a maximum number of 6 cycles of Radium-223 therapy according to current clinical guidelines and will undergo response evaluation by ceCT and bone scans upon clinical progression. At clinical progression, each patient will undergo a second 68Ga-PSMA-PET/CT to determine the location of disease progression and assess the value of 68Ga-PSMA-PET/CT imaging as a response measure. The clinical response of Radium-223 therapy in the patients with bone-only disease according to 68Ga-PSMA-PET/CT scanning, will be compared to the treatment outcomes collected in our previously reported ROTOR registry. Secondary aims are to determine the value of ctDNA as predictive biomarker and the value of 68Ga-PSMA-PET/CT imaging in the response assessment.

  • 18F-Fluciclovine PET/CT Impact on Predicting Clinical Outcome of 177Lu-PSMA-617 Therapy in Patients With Prostate Cancer

    The imaging analysis will consist in obtaining quantitative measurements of lesion uptake on the pre- and post-LuPSMA RLT (lesion and whole-body SUVmax, SUVmean and tumor volume) at each time point on all PET/CT scans. PET metrics at the lesion- and whole-body level will be compared among different PET radiopharmaceuticals at the same time point, and changes over time will be assessed. All patients will be followed-up at our institution and clinical outcome will be correlated to the imaging analysis assessment.

  • Macrophage PET/CT Imaging Using 64Cu-DOTATATE for the Diagnosis of Cardiac Sarcoidosis

    Cardiac involvement is considered a serious condition and a frequent cause of death in patients with sarcoidosis. 18F-FDG PET/CT is currently used as part of the diagnostic criteria for cardiac sarcoidosis, but it has shown limitations in the evaluation of cardiac sarcoidosis due to the high physiological uptake of FDG in normal cardiac muscle. Elaborate preparations are required for patients including either a low-carbohydrate diet followed by long fasting or heparin loading before FDG-PET. In heparin loading, the rare adverse effect of heparin-induced thrombocytopenia should be considered. Therefore, it is of interest to find a PET/CT tracer that displays high sensitivity and specificity without requiring thorough patient preparation and minimizing any adverse effects. A potential tracer is the somatostatin-based tracer 64Cu-DOTATATE, which is routinely used for the diagnosis and monitoring of treatment response in patients with neuroendocrine tumors. Inflammatory cells, including macrophages that are found in sarcoid granulomas, express somatostatin receptors on their surface, whereas normal cardiomyocytes do not. This allows for the potential use of macrophage imaging in cardiac sarcoidosis. In the CuDOSIS trial, groups A and B (suspected and confirmed cardiac sarcoidosis, respectively) will be scanned with 64Cu-DOTATATE PET/CT in addition to the routinely performed 18F-FDG PET/CT. Further, to examine whether the macrophage infiltration pattern is different in patients with cardiac sarcoidosis and other inflammatory heart diseases, a group of patients with confirmed or clinically suspected myocarditis will be included (group C); this group will only be scanned with 64Cu-DOTATATE PET/CT. Finally, data from a group of patients with neuroendocrine tumours (negative controls) who have previously been scanned with 64Cu-DOTATATE will be included.

  • A Study Evaluating the Value of 68Ga-NOTA-RCCB6 PET Imaging for Targeting CD70 in the Clinical Staging, Therapeutic Evaluation, and Restaging of Renal Cell Carcinoma, and Comparing It with 68Ga-PSMA PET/CT Imaging

    This research process is divided into screening period, baseline period, safety visit period, and diagnostic efficacy follow-up period. 1. Screening period (D-7 to D-1): No more than 7 days Screening is conducted within 7 days before the administration of 68Ga-NOTA-RCCB6 (D-7 to D-1). Before any study-related procedures, subjects must sign a written informed consent form. After signing the informed consent form, the following screening procedures are performed: ① Review of inclusion/exclusion criteria. - Collection of medical history, including but not limited to clinical data of the subjects and relevant auxiliary examination results (routine imaging examinations, tumor markers, biopsy results, etc.), numbering each subject and establishing a medical record. - Collection of demographic data (including gender, age, etc.). ④ Recording of concomitant medications/adverse events. If any inclusion criteria are not met or any exclusion criteria are met, the screening is considered failed. 2. Baseline period (drug/administration period) (D0): 1 day Subjects who meet all inclusion criteria and do not meet any exclusion criteria will receive an injection of 68Ga-NOTA-RCCB6 and undergo a PET/CT scan on D0. The following assessments are performed again before administration, and only after a comprehensive evaluation by the doctor are they eligible for injection. - Concomitant medications after screening visit ② Weight - Vital signs - Adverse events Single dose, 0.05-0.1mCi/kg body weight, intravenous injection of 68Ga-NOTA-RCCB6 0.05-0.1mCi/kg PET/CT scan is performed 50-80 minutes after administration. 3. Safety visit period (D0 to D4): 4 days - Follow-up on whether subjects have adverse reactions after administration. ② 2 hours ± 10 minutes after administration: monitoring of adverse events in subjects. ③ 1-4 days after administration: telephone follow-up to assess for delayed adverse events. 4. Diagnostic efficacy follow-up period (D1 to D180): 6 months Follow-up on biopsy/surgical pathology results of subjects (preferably completed within 1 month after imaging) and imaging results to confirm the diagnostic efficacy of 68Ga-NOTA-RCCB6 PET/CT in renal cell carcinoma. When conducting diagnostic efficacy follow-up, the following should be recorded simultaneously: concomitant medications and adverse events. 5. Withdrawal from study/premature termination of study If patients do not complete the PET examination according to the process, for subjects who withdraw prematurely, the following follow-up should be completed: ① Concomitant medications ② Adverse events 6. Premature termination or suspension of study Reasons for study termination may include but are not limited to: new information on safety, requirements of the competent authorities. Other reasons include but are not limited to: excessive protocol violations, insufficient concern for subject safety, researcher turnover or insufficient staffing, etc. In the event of any of the following situations during the study, the study may be terminated, and the competent authority should promptly report to the health department responsible for clinical research registration: - There is a violation of laws and regulations, rules; - There is a violation of ethical principles or the principles of scientific integrity; - During the study, it is found that the study drug may have serious quality defects; ④ Serious safety risks are found in clinical research; - There is commercial bribery or other improper interest relationships; ⑥ Other situations that should stop the study. For all situations where the study is suspended or terminated, appropriate steps will be taken to ensure the safety of the subjects. Definition of study completion: PET imaging, result analysis, and necessary clinical follow-up of all study subjects have been completed.
