Methylprednisolone Before Fludeoxyglucose-Labeled Positron Emission Tomography in Patients With Lung Cancer

Not Applicable
Withdrawn
Conditions
Lung Cancer
Interventions
Radiation: fludeoxyglucose F 18
Procedure: positron emission tomography
Procedure: computed tomography
Registration Number
NCT01789892
Lead Sponsor
Ohio State University Comprehensive Cancer Center
Brief Summary

The purpose of this study is to determine whether giving an anti-inflammatory medication (corticosteroid) prior to a positron emission tomography scan (PET) scan may reduce or eliminate false findings related to inflammation

Detailed Description

PRIMARY OBJECTIVES:

I. To assess whether premedication with a corticosteroid may reduce false positive findings on fluorodeoxyglucose (fludeoxyglucose F 18 \[FDG\[) PET/computed tomography (CT) scans in lung cancer patients, by reducing radiotracer uptake in thoracic lymph nodes related to inflammation.

OUTLINE:

Within 1-14 days of undergoing standard FDG PET/CT scan, patients receive methylprednisolone intravenously (IV) and then undergo a second FDG PET/CT scan.

After completion of study treatment, patients are followed up for 2 years.

Primary Outcome Measures
NameTimeMethod
Continuous standardized uptake values (SUV)Within 1-14 days of first scan

The SUV on the first and second PET scans will be recorded and summarized on a receiver operating characteristic (ROC) curve. We will explore the ROC curve for percent change in SUV or uptake ratio from the first to the second scan. We will explore thresholds for SUV and uptake values on the ROC curve by determining the values of acceptable combinations of true positive fractions (TPF) and false positive fractions (FPFs). We will use regression methods to adjust for possible confounding patient demographics, disease severity and disease history.
