Abstract
Sinonasal cancers are rare but have a poor prognosis. Most previous studies of these cancers have focused on 5-year disease-free survival, but recurrences are also known to occur after this period. We examined the post-5-year recurrence patterns in sinonasal cancer patients by histologic type to determine the indicators for extended and close follow-up requirements. Retrospective chart review. A cohort of 241 sinonasal cancer patients was included. Demographic data, cancer site and stage, pathology and treatment results, and follow-up and survival data were collected. Of the 241 patients, a complete remission occurred in 163 (72.4%) patients, but 83 (50.9%) of these cases developed recurrence, which occurred beyond the 5-year follow-up period in 19 cases (11.7%). The most common post-5-year recurrences were adenoid cystic carcinoma (six patients, 33.3%), followed by melanoma (three patients, 21.4%), poorly differentiated carcinoma (two patients, 18.2%), squamous cell carcinoma (six patients, 6.7%), and olfactory neuroblastoma (no patients, 0%). Post-5-year local recurrence was highest in adenoid cystic carcinoma (six patients, 33.3%), followed by melanoma (three patients, 21.4%), poorly differentiated carcinoma (two patients, 1...Continue Reading
