The Value of [18F]FDG PET/CT Imaging in Prognostic Evaluation of Mucosal Melanoma

Union Hospital, Tongji Medical College, Huazhong University of Science and Technology68 enrolled

Overview

This project will target patients with histopathologically diagnosed mucosal melanoma using \[¹⁸F\]FDG PET/CT imaging for retrospective prognostic evaluation.The primary objective is to explore the value of \[¹⁸F\]FDG PET/CT imaging in the prognostic assessment of mucosal melanoma, and to determine the correlations between quantitative \[¹⁸F\]FDG PET parameters and progression-free survival (PFS) as well as overall survival (OS), so as to provide reference evidence for individualized treatment decision-making.

Outcomes

Primary Outcomes

Overall survival

Overall survival (OS) is defined as the time elapsed from the date of the ¹⁸F-FDG PET/CT examination to the date of death.

Time frame: Up to 4 years

Progression-free survival

Progression-free survival (PFS) is defined as the time from the date of \[18F\]FDG PET/CT imaging to the earliest date of disease progression, recurrence, or death.
