Not Applicable
Completed
Conditions
Molecular Imaging
Interventions
Radiation: 18F-IRS
Registration Number
NCT03031522
Lead Sponsor
Harbin Medical University
Brief Summary

The investigators developed 18F-IRS as a targeted molecular imaging agent for noninvasive and repeatable detecting EGFR-activating mutational status.

Detailed Description

The goal of investigators were to evaluate the use of 18F-IRS as a novel PET/CT radiotracer to monitor EGFR-activating mutational status and identify EGFR-TKIs benefit NSCLC patients. the investigators want to evaluated the use of 18F-IRS in lung cancer imaging in adult NSCLC patients with different EGFR mutational status of primary and metastatic cancers.

Primary Outcome Measures
NameTimeMethod
tumor SUVmax value of 18F-IRS PET/CT Imagingat time of imaging

To quantify the accumulation, a volume of interest using a 3-D sphere, was placed over the primary lung tumor, lymph nodes and distant metastases avoiding necrosis, blood vessels and normal lung tissue as much as possible on a workstation (Advantage Workstation 4.6; GE Healthcare). The maximum standard uptake value (SUVmax) normalized to body weight (kBq/mL) was calculated within the region of interest.
