About this study

Subjects with various FAP-related disease patients underwent 68Ga/18F-PD-L1 PET/CT either for an initial assessment or for recurrence detection. Lesions uptake was quantified by the maximum standard uptake value (SUVmax). The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of 68Ga/18F-PD-L1 PET/CT were calculated

Who can participate

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • (i) adult patients (aged 18 years or order); (ii) patients with suspected or new diagnosed or previously treated malignant tumors (supporting evidence may include MRI, CT, tumor markers and pathology report); (iii) patients who had scheduled PD-L1 PET/CT scan; (iv) patients who were able to provide informed consent (signed by participant, parent or legal representative) and assent according to the guidelines of the Clinical Research Ethics Committee.

Exclusion criteria

  • (i) patients with non-malignant lesions; (ii) patients with pregnancy; (iii) the inability or unwillingness of the research participant, parent or legal representative to provide written informed consent.

Treatment and study plan

Single Group Assignment

Diagnostic Test

Each subject receive a single intravenous injection of 68Ga/18F-DMP10 or other PDL1 tracers, and undergo PET/CT imaging within the specificed time.

Primary outcomes

  1. Standardized uptake value (SUV)

    Time frame: 30 days

    Standardized uptake value (SUV) of PD-L1 for each target lesion of subject or suspected primary tumor or/and metastasis.

Secondary outcomes

  1. Diagnostic efficacy

    Time frame: 30 days

    The sensitivity, specificity and accuracy of PD-L1 PET/CT were calculated.
