NCT05963035

Brief Summary

This study is a prospective monocentric study aimed to evaluate the diagnosis and staging value of 18F-PFPN PET in clear cell sarcoma of soft tissue. Patients with clinically suspected or confirmed clear cell sarcoma of soft tissue will be recruited and 18F-PFPN PET/MR imaging will be performed. PET/CT imaging will be performed in patients with contraindications to MR. Additionally, to compare the diagnostic efficacy with the traditional imaging agent 18F-FDG, patients will also undergo 18F-FDG PET imaging, and the two imaging intervals will be completed two days apart. The general information, clinical data, 18F-PFPN and 18F-FDG PET/MR or PET/CT imaging results and other imaging data of the patients will be collected. The histopathology of the biopsy or surgical specimen, follow-up and other imaging examinations will be taken as evaluation references. This study plans to set the sample size as 10 cases.

Outcome Measures

Primary Outcomes (1)

  • Sensitivity and specificity of 18F-PFPN PET for diagnosis and staging of clear cell sarcoma of soft tissue

    18F-PFPN and 18F-FDG PET/MR or PET/CT images will be analyzed by at least 2 physicians experienced in nuclear medicine and radiology. The general information, clinical, histopathological and imaging data of patients will be collected and analyzed to calculate the sensitivity and specificity of 18F-PFPN for diagnosis and staging in clear cell sarcoma of soft tissue.

Study Arms (1)

18F-PFPN PET

EXPERIMENTAL

A positron probe for the targeted melanin

Drug: 18F-PFPN

Interventions

For patients clinically suspected or confirmed clear cell sarcoma of soft tissue, integrated PET/MR or PET/CT imaging will be performed using targeted melanin-specific imaging agent 18F-PFPN. Meanwhile, multiple parameters will be compared with the general imaging agent 18F-FDG.

Also known as: 18F-PEG3-FPN
18F-PFPN PET
