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

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.

Primary outcomes

  1. Overall survival

    Time frame: Up to 4 years

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

  2. Progression-free survival

    Time frame: Up to 4 years

    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.
