Exploratory analysis of radiomic as prognostic biomarkers in F-FDG PET/CT scan in uterine cervical cancer.

Objective: To evaluate the performance of 18F-fluorodeoxyglucose positron emission tomography (F-FDG PET/CT) radiomic features to predict overall survival (OS) in patients with locally advanced uterine cervical carcinoma.

Methods: Longitudinal and retrospective study that evaluated 50 patients with cervical epidermoid carcinoma (clinical stage IB2 to IVA according to FIGO). Segmentation of the 18F-FDG PET/CT tumors was performed using the LIFEx software, generating the radiomic features.
