Overview
To determine the dose of Pluvicto therapy absorbed in the tumors and organs of patients whose kidneys and/or bone marrow are not working properly.
Description
Primary Objectives
• To determine the personalized radiation dose to tumors and critical organs of participants with compromised renal and / or bone marrow function.
Secondary Objectives
- To compare target radiation doses based on varying SPECT scan duration. Plot the variability in target radiation dose versus scan duration.
- To compare the image quality and dosimetry results when considering the low, high, and both energy peaks of Lu-177.
- To compare target radiation doses based on multiple imaging time points versus a single time point and identify which time point is most suited for this evaluation.
- To compare target radiation doses derived from organ versus voxel dosimetry calculation.
Eligibility
Eligibility Criteria
- Participants that are approved for Pluvicto therapy and have been identified to have renal complications or compromised marrow function. Renal complication is defined as GFR: 30-50ml/min, creatinine: ULN-twofold ULN; while compromised marrow function is indicated by total WBC 2.5 x 109 L - LLN, or platelet count 75-100 x 109 L.
- Participants who agree to be imaged multiple times as defined in the study protocol.
Exclusion Criteria
- Pluvicto therapy patients without renal or marrow function complications
- Participants who do not wish to be imaged multiple times as per the study protocol.
- Women and children since this is treatment for prostate cancer.
