ABSTRACT
BACKGROUND:
The purpose of this study was to assess the utility of imaging and endoscopy in posttreatment surveillance of sinonasal malignancies.METHODS:
We conducted a retrospective analysis of primary sinonasal malignancies diagnosed between 2000 and 2014. Posttreatment surveillance included nasal endoscopy and imaging (MRI, CT, and positron emission tomography [PET]/CT). Positive predictive value (PPV), negative predictive value (NPV), specificity, and sensitivity were calculated for each modality and compared.RESULTS:
One hundred nine sinonasal malignancies were identified with 30 recurrences. Endoscopy showed a sensitivity and specificity of 24% and 89%, respectively, whereas imaging was 76% and 90%, respectively. Identifying suspicious symptoms significantly improved the PPV of both endoscopy and imaging. MRI demonstrates the highest PPV when compared with other imaging modalities.CONCLUSION:
Both modalities are necessary in posttreatment surveillance. MRI shows the highest PPV, whereas endoscopy trends toward a higher specificity. PET/CT scans have a high false-positive rate and should be reserved for tumors with a high propensity for distant metastases. © 2016 Wiley Periodicals, Inc. Head Neck 381229-1233, 2016.Key words
