Sodium Fluoride PET/CT for the Evaluation of Skeletal Cancer

Not Applicable
Terminated
Conditions
Bone Cancer
Interventions
Radiation: fluorine F 18 sodium fluoride
Procedure: positron emission tomography/computed tomography
Registration Number
NCT01541358
Lead Sponsor
Stanford University
Brief Summary

This clinical trial studies fluorine F-18 sodium fluoride positron emission tomography (PET)/computed tomography (CT) in diagnosing bone tumors in patients with cancer. Diagnostic procedures, such as fluorine F-18 sodium fluoride PET/CT, may help find and diagnose bone cancer

Detailed Description

The objective of the study is to use 18F sodium fluoride (fluorine F-18 sodium fluoride) PET/CT scanning to detect and characterize lesions in patients who have suspected skeletal malignancy. We hypothesize that scanning with 18F-NaF (fluorine F-18 sodium fluoride) is more sensitive for skeletal abnormalities and may better characterize lesions than conventional imaging.

Primary Outcome Measures
NameTimeMethod
Total Number of Lesions Identified by F-18 NaF PET/CT in Patients With Suspected Skeletal Malignancyan estimated average of 2 hours

F-18 NaF is a positron emission tomography (PET) bone imaging agent that targets changes in the bone. The fluoride ions are taken up in areas of the bone that have increased bone remodeling (bone repair) and increased blood flow, which is indicative of diseases such as cancer.

Secondary Outcome Measures
NameTimeMethod
Specificity of F-18 NaF PET/CT to Detect Bone Lesions in Patients With Suspected Skeletal Malignancyan estimated average of 2 hours

Specificity is the ability of a test to correctly determine the absence of disease (true negative). This study determined how accurately F18 NaF PET/CT performed at detecting the absence of disease.

The calculation for specificity is TN / (TN + FP), where:

TN = the participant was a true negative (the lesion was not detected on F18 NaF PET/CT and the patient does not have the disease) FP = the participant was a false positive (the lesion was falsely detected on the F18 NaF PET/CT and the patient does not have the disease) The result is expressed as a percentage.

Sensitivity of F-18 NaF PET/CT to Detect Bone Lesions in Patients With Suspected Skeletal Malignancyan estimated average of 2 hours

Sensitivity is the ability of a test to correctly identify those with the disease (true positive rate). This study determined how many lesions were detected by F18 NaF PET/CT compared to the known results. The calculation for sensitivity is TP / (TP+FN), where:

TP = true positive (the lesion was accurately detected on both F18 NaF and comparison study) FN = false negative (the lesion was not detected on the PET/CT but was detected on the comparison study)

The result is expressed as the percentage of confirmed lesions across all participants that were also detected by F18 NaF PET/CT.
