Utility of first positron emission tomography‐computed tomography scan as a prognostic tool following treatment of sinonasal and skull base malignancies

Abstract

Background

The prognostic value of the first posttreatment whole body integrated positron emission tomography‐computed tomography (PET/CT) scanning in patients with sinonasal/skull base malignancies is undetermined.

Methods

We retrospectively reviewed the data of all patients that underwent surgery for sinonasal/skull base malignancies in 2000‐2015. The results of the pretreatment and posttreatment PET/CT findings and the clinical course were retrieved.

Results

Thirty‐eight patients (average age 60.6 years, 20 males) were included. Sensitivity and specificity, positive predictive value, and negative predictive value of the first PET/CT scan for predicting persistent/recurrent disease were 85.7%, 87.5%, 80%, and 91.3%, respectively. Overall 5‐year survival was significantly lower in the first posttreatment PET/CT‐positive group (35%) compared to the PET/CT‐negative group (93%) (P = .0008).

Conclusion

Posttreatment PET/CT findings are highly prognostic in patients with sinonasal/skull base malignancies. Negative findings on the first posttreatment PET/CT scan predict a significantly better overall survival.
