Summary

This is an open-label SPECT/CT (single photon emission computed tomography / computed tomography) study to investigate clinical study of 99mTc-3PRGD2 SPECT/CT in diagnosis and efficacy evaluation of breast cancer. Diagnostic group: for patients in suspicion of breast cancer. The standard of truth for diagnosis was based on histopathologic findings after surgical removal of the tumor or a definite diagnosis from fine needle aspiration biopsy. A single dose of nearly 0.3 mCi/kg (milli-Curie/kilogram) body weight of 99mTc-3PRGD2 ( ≤ 20 µg 3PRGD2) will be intravenously injected into the patients. Visual and semiquantitative method will be used to assess the whole-body planar and lesions SPECT/CT images.

Efficacy evaluation group: for patients firstly diagnose with malignant tumors (breast cancer), and prepare to chemotherapy(including neoadjuvant chemotherapy) or radiotherapy. The standard of truth for diagnosis was based on histopathologic findings after fine needle aspiration biopsy. A single dose of nearly 0.3 mCi/kg body weight of 99mTc-3PRGD2 ( ≤ 20 µg 3PRGD2) will be intravenously injected into the patients before treatment, the second period, sixth period. Visual,semiquantitative method will be used to assess the whole-body planar and lesions SPECT/CT images. By comparing with result of the other related imaging, for instance, PET/CT (positron emission tomography/computed tomography), CT (computed tomography), MRI (magnetic resonance imaging), Doppler Ultrasound, Mammography, etc.

99mTc-3PRGD2

Diagnostic group：For patients in suspicion of breast cancer, single intravenous bolus injection of nearly 0.3 mCi/kg body weight of 99mTc-3PRGD2 on day one of the treatment period, whole-body planar and lesions SPECT/CT to determine the accumulation of 99mTc-3PRGD2 in the tumors and the other parts of the body. Efficacy evaluation group：patients firstly diagnose with malignant lesions ,and prepare to chemotherapy(including neoadjuvant chemotherapy) or radiotherapy.the same dose of 99mTc-3PRGD2 will be intravenously injected into the patients before treatment ,the second period,the sixth period( almost three months after the initial treatment)，whole-body planar and lesions SPECT/CT to assess the value of 99mTc-3PRGD2 in evaluation of cancers.
