Summary
Brief summary (as posted)
This is a prospective, multicenter, self-controlled phase 3 clinical trial designed to evaluate the safety and efficacy of an integrin αVβ3-targeted imaging, 99mTc-3PRGD2 SPECT/CT, for diagnosis of lung cancer and mapping the lymph node metastases. The pathological results will be considered as the gold standard and the conventional metabolic imaging by 18F-FDG PET/CT will be used for a head-to-head comparison. The primary objective of this study is to evaluate the efficacy of 99mTc-3PRGD2 SPECT/CT in mapping of lymph node metastasis according to the nodal mapping system released by the International Association for the Study of Lung Cancer in 2009 (IASLC-2009). The secondary objectives include evaluation of 99mTc-3PRGD2 SPECT/CT in detection of lung cancer and the safety of 99mTc-3PRGD2 injection in human beings.

- label
- 99mTc-3PRGD2 injection for SPECT/CT imaging, with 18F-FDG PET/CT for head-to-head comparison.
- description
- Participants will receive a single-dose intravenous injection of 99mTc-3PRGD2 at a dosage of approximate 11.10 MBq (0.30 mCi) per kilogram body weight. Whole-body planar scan and chest SPECT/CT imaging will be performed 40-50 min later. Chest low-dose spiral CT (120 kV, 50 mAs) will be used for attenuation correction and anatomical localization. The conventional metabolic imaging by 18F-FDG PET/CT of the same patients within one week will be used for a self-controlled head-to-head comparison.

Primary outcomes (1)
- measure
- Evaluate whether the diagnostic specicity of 99mTc-3PRGD2 SPECT/CT is superior to that of 18F-FDG PET/CT in mapping lymph node metastasis of lung cancer in the same group of patients.
- timeFrame
- From the informed consent of the first participant to 2 weeks after the intervention of the last participants or until the last participant accepted surgery within 2 weeks
- description
- Using the pathological results as the gold standard, calculate the specificity of 99mTc-3PRGD2 SPECT/CT in mapping of lymph node metastasis of lung cancer according to the nodal mapping system released by the International Association for the Study of Lung Cancer in 2009 (IASLC-2009), and compared it head-by-head with that of the conventional metabolic imaging by 18F-FDG PET/CT in the same group of patients. And then assess if the specificity of 99mTc-3PRGD2 SPECT/CT is superior to that of 18F-FDG PET/CT.
