ObjectiveTo analyze outcomes and prognostic factors of sinonasal nonsalivary non-intestinal-type adenocarcinoma (n-ITAC.) METHODS: A retrospective review of 22 consecutive patients with n-ITAC was performed.ResultsAverage follow-up time was 77 months. The 5-year overall survival and disease-specific survival were 95.2%. The 5-year overall survival and disease-specific survival were 100% for pT1, pT2, and pT3 tumors and 83.3% for pT4a and pT4b tumors; 100% for G1 tumors and 87.5% for G3 tumors; and 100% for tumors with negative surgical margin and 50% for tumors with positive surgical margin. Stage, grade, and surgical margins were independent prognostic factors. Adjuvant radiotherapy was performed for high-grade and high-stage tumors.ConclusionsSurgery followed by radiotherapy has remained a mainstay for management of n-ITAC, and the endoscopic transnasal approach, when correctly planned and indicated, is the surgery of choice. Adjuvant radiotherapy is recommended in cases of high-stage (T3 and T4) and high-grade tumors. n-ITAC is associated with a favorable outcome. High grade, pT4 stage, and positive surgical margins are independent negative prognostic factors.Copyright © 2018. Published by Elsevier Inc.
