Patients
The study was reviewed and approved by the local Institutional Review
Board (IRB). We conducted a retrospective review of the medical database
of our tertiary medical center for all patients treated for NPC between
2000-2018.
Inclusion criteria were adult patients (age>18 years) who
had at least one year of follow up. Patients with primary sinonasal
malignancies were excluded.
Data retrieved included patient demographics as well as treatment
modalities, imaging, tumor pathology and follow up data.
