About this study

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.

Read the detailed description

Clear cell sarcoma of soft tissue is a rare malignancy derived from neural crest cells that contain melanin and/or melanin precursors. Melanin is an important target for the diagnosis of clear cell sarcoma of soft tissue. 18F-PFPN, a highly specific melanin-targeting positron probe, has been proven to have excellent pharmacokinetic properties and good biological safety, and can sensitively detect tiny melanin-containing lesions. Therefore, 18F-PFPN PET imaging is expected to be used in diagnosing and staging clear cell sarcoma of soft tissue.

This study was designed as a prospective study to explore the diagnosis and staging value of 18F-PFPN PET in clear cell sarcoma of soft tissue. In this study, patients with clinically suspected or confirmed clear cell sarcoma of soft tissue will be recruited to undergo 18F-PFPN PET/MR imaging. PET/CT imaging will be performed in patients with contraindications to MR. The general information, clinical data, imaging data and histopathology results of patients will be collected. The efficiency of diagnosis and staging of 18F-PFPN was evaluated by comparing the gold standard pathological diagnosis and the general metabolic imaging agent 18F-FDG.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 18F-PFPNDrug

    Also called 18F-PEG3-FPN

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

    Measured: 1 years

Questions about this trial

What is this clinical trial studying?

A study testing 18F-PFPN in people with Clear Cell Sarcoma of Soft Tissue, run by Union Hospital, Tongji Medical College, Huazhong University of Science and Technology at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 27 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Xiaoli Lan (0086-027-83692633, lxl730724@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sensitivity and specificity of 18F-PFPN PET for diagnosis and staging of clear cell sarcoma of soft tissue (time frame: 1 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05963035, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jul 2023.
