Detailed Description
The goals of investigators are to evaluate the use of [68Ga]-labelling Anti-EGFR Affibody Molecule as a novel PET/CT radiotracer to monitor EGFR-ECD expression status and classify EGFR-ECD benefit NSCLC patients. The investigators want to evaluated the use of [68Ga]-labelling Anti-EGFR Affibody Molecule in lung cancer imaging in adult NSCLC patients with different EGFR-ECD expression status of primary and metastatic cancers.

Outcome Measures
Primary Outcome Measures
- tumor SUVmax value of 68Ga-NODAGA-ZEGFR:1907 PET/CT Imaging [at 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.
