Clinical Trial Summary

The incidence and mortality of hematological malignancies remain high. Although 18F-FDG PET/CT imaging is the most common molecular imaging technique used in clinic, the non-specific uptake of 18F-FDG leads to the problems of false negative or positive in hematological malignancies, which makes it difficult to diagnose and evaluate the efficacy. CXCR4 (C-X-C Chemokine Receptor Type 4) is overexpressed in various hematological malignancies, and is associated with poor prognosis. CXCR4-targeted molecular imaging, such as 68Ga-pentixafor PET/CT imaging, has an important potential in hematological malignancies. Therefore, this study will evaluate the efficacy of CXCR4-targeted PET/CT imaging for diagnosis and staging of hematological malignancies, compared with 18F-FDG PET/CT imaging.

Outcome

Type Measure Description Time frame Safety issue
Primary Sensitivity of 68Ga-pentixafor PET/CT for diagnosis and staging in hematological malignancies. For subjects with clinically highly suspected, or newly diagnosed, or relapsed hematological malignancies who undergo 68Ga-pentixafor and 18F-FDG PET/CT imaging in one week. Diagnosis and staging results of 68Ga-pentixafor PET/CT will be compared to 18F-FDG PET/CT imaging, pathology and clinical follow-up results. Two years
Primary Specificity of 68Ga-pentixafor PET/CT for diagnosis and staging in hematological malignancies. For subjects with clinically highly suspected, or newly diagnosed, or relapsed hematological malignancies who undergo 68Ga-pentixafor and 18F-FDG PET/CT imaging in one week. Diagnosis and staging results of 68Ga-pentixafor PET/CT will be compared to 18F-FDG PET/CT imaging, pathology and clinical follow-up results. Two years
Primary Accuracy of 68Ga-pentixafor PET/CT for diagnosis and staging in hematological malignancies. Taking the pathology or clinical follow-up as gold standard, the probability of accurate diagnosis and staging (including true positive and true negative) for 68Ga-pentixafor PET/CT imaging will be calculated in subjects with clinically highly suspected, or newly diagnosed, or relapsed hematological malignancies. The result will be compared to 18F-FDG PET/CT imaging. Two years
