What this trial studies

This study evaluates the effectiveness of 18F-PFPN PET imaging in diagnosing and staging clear cell sarcoma of soft tissue, a rare malignancy. Patients with suspected or confirmed cases will undergo both 18F-PFPN PET/MR imaging and 18F-FDG PET imaging to compare their diagnostic efficacy. The study aims to collect clinical data, imaging results, and histopathology to assess the performance of 18F-PFPN in detecting melanin-containing lesions. A total of 10 cases will be included in this prospective monocentric study.

Who should consider this trial

Good fit: Ideal candidates are adult patients aged 18 and above with clinically suspected or confirmed clear cell sarcoma of soft tissue.

Not a fit: Patients with acute systemic diseases, those who are pregnant or breastfeeding, or those unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the accuracy of diagnosing and staging clear cell sarcoma of soft tissue, leading to better treatment outcomes.

How similar studies have performed: While the use of 18F-PFPN PET imaging is novel, similar imaging approaches have shown promise in other malignancies.
