Trial Outcomes & Findings for Combined 18F-NaF/18F-FDG PET/MRI for Detection of Skeletal Metastases (NCT NCT00375830)

NCT ID: NCT00375830

Last Updated: 2023-12-12

Results Overview

The medical value of 18F-sodium fluoride (NaF) positron emission tomography / computed tomography (PET/CT) vs 99mTc-methylene diphosphonate (MDP) bone scintigraphy was assessed on the basis of the radiation oncologist's medical assessment of image quality and detected extent of disease, for each participant. Per protocol, the data were collected and the outcome is reported for Cohort 1 only. The outcome is reported as the number of participants for whom the medical value of the image was superior for 18F-NaF vs 99mTc-MDP bone scintigraphy ("18F-NaF \> 99mTc-MDP"), the same between both scans ("18F-NaF = 99mTc-MDP"), or inferior for 18F-NaF vs 99mTc-MDP bone scintigraphy ("18F-NaF \< 99mTc-MDP").

Timeframe: 30 days

Population: This assessment was conducted only for Cohort 1, and only for participants with skeletal metastases, as part of the "pilot phase" of the study.

The medical value of 18F-sodium fluoride (NaF) positron emission tomography / computed tomography (PET/CT) vs 18F-fluorodeoxyglucose (FDG) positron emission tomography / computed tomography (PET/CT) was assessed on the basis of the radiation oncologist's medical assessment of image quality and detected extent of disease, for each participant diagnosed with osseous (skeletal) metastases. Per protocol, the data were collected and the outcome is reported for Cohort 1 only. The outcome is reported as the number of participants for whom the medical value of the image was superior for 18-NaF PET/CT compared to 18F-FDG PET/CT, the same between both scans, or inferior for 18-NaF PET/CT compared to 18F-FDG PET/CT. The outcome result is represented as a number without dispersion.

Timeframe: 30 days

Population: For this outcome, participants in Cohort 2 were analyzed with 2 distinct scanning procedures, ie, 18F-NaF/18F-FDG PET/CT scan and whole-body MRI scan.

Sensitivity; positive predictive value (PPV); and accuracy for the detection of extraskeletal lesions was assessed for 18F-sodium fluoride (NaF) / 18F-fluorodeoxyglucose (FDG) positron emission tomography / computed tomography (PET/CT) and for whole body magnetic imaging resonance (WB-MRI). * Sensitivity is a percentage that defines the proportion of true positive participants with the disease in a total group of participants. * PPV is the probability that participants with a positive screening test truly have the disease. * Accuracy is the proportion of true results (both true positives and true negatives) among the total number of cases examined. Per protocol, the data were collected and the outcome is reported for Cohort 2 only. Sensitivity, PPV, and accuracy are reported as a percentage, a number without dispersion. Higher numbers represent better detection.

SECONDARY outcome

Timeframe: 30 days

Sensitivity and accuracy for the detection of skeletal lesions was assessed for 18F-sodium fluoride (NaF) / 18F-fluorodeoxyglucose (FDG) positron emission tomography / computed tomography (PET/CT) and for 99mTc-methylene diphosphonate (MDP) bone scintigraphy. Per protocol, the data were collected and the outcome is reported for Cohort 2 only. Sensitivity and accuracy are reported as a percentage, a number without dispersion. Higher numbers represent better detection.

Timeframe: 30 days

Overall sensitivity and accuracy for the detection of tumor lesions was assessed for 18F-sodium fluoride (NaF) / 18F-fluorodeoxyglucose (FDG) positron emission tomography / computed tomography (PET/CT) and for whole body magnetic imaging resonance (WB-MRI). Per protocol, the data were collected and the outcome is reported for Cohort 2 only. Sensitivity and accuracy are reported as a percentage, a number without dispersion. Higher numbers represent better detection.
