Study Details

Study Description

Brief Summary

PSMA is highly expressed on the cell surface of the microvasculature of several solid tumors, including breast cancer. This makes it a potentially imaging target for the detection and grading of breast cancer. This pilot study was designed to evaluate the diagnostic performance of 68Ga-P16-093, a novel radiopharmaceutical targeting PSMA, which was compared with 18F-FDG in the same group of breast cancer patients.

Condition or Disease Intervention/Treatment Phase
  • Diagnostic Test: Drug: 68Ga-P16-093
Phase 1/Phase 2

Detailed Description

PSMA has been confirmed to be over expressed in vascular endothelial cells of various malignant solid tumors, such as breast cancer and renal cancer, which can provide growth advantages for various cancers by cutting the signal molecules involved in angiogenesis. Positron emission tomography (PET) imaging using radiolabeled molecules targeting PSMA can detect a variety of non prostate cancer solid tumors such as breast cancer and glioma. According to previous studies, PSMA can detect primary and metastasis lesions of breast cancer patients, and has a higher uptake value in triple negative breast cancer and HER2 overexpressed patients. The uptake may be related to tumor grade.

Arms and Interventions

Arm Intervention/Treatment
Experimental: 68Ga-P16-093 and 18F-FDG scan

Within 1 week, each patient underwent 68Ga-P16-093 and 18F-FDG PET/CT scan after intravenous administration of 68Ga-P16-093 and 18F-FDG, respectively.

Diagnostic Test: Drug: 68Ga-P16-093
Intravenous injection of 68Ga-P16-093 with the dosage of 1.5-1.8 MBq (0.04-0.05 mCi)/kg. Tracer doses of 68Ga-P16-093 will be used to image lesions of breast cancer by PET/CT.

Outcome Measures

Primary Outcome Measures

  1. Diagnostic performance [through study completion, an average of 1 year]

    comparing the number of tumor detected by 68Ga-P16-093 and 18F-FDG

Secondary Outcome Measures

  1. standardized uptake value (SUV) of tumor [through study completion, an average of 1 year]

    comparing the SUVmax of tumor of different lesions derived from 68Ga-P16-093 AND 18F-FDG
