Detection and prediction of local recurrence of maxillary sinus cancer using F-18 FDG PET/CT

Abstract Purpose The aim of the current study was to investigate the role of F-18 FDG PET/CT in the detection and prediction of local recurrence of maxillary sinus cancer. Methods Retrospectively, we analyzed F-18 FDG PET/CT images of maxillary sinus cancer patients for the surveillance after treatment. Twenty-two consecutive patients with maxillary sinus cancer, who underwent maxillectomy followed by adjuvant radiation treatment, were included in the study. F-18 FDG PET/CT images were analyzed visually and quantitatively. Results The median age of the patients included in the current study population was 54.5 years (range, 35–78). Seven patients (29.1%) had local recurrent diseases. Recurrent diseases show statistically significant higher values in SUVmax (recurrent: 5.09 ± 3.3, non-recurrent; 3.05 ± 0.7, p
