Clinical and morphological aspects of adenocarcinomas of the intestinal type in the inner nose: a retrospective multicenter analysis

Abstract

Clinical and histological parameters from 117 patients with wood dust-related sinonasal adenocarcinomas of intestinal type (ITAC) were analyzed and correlated with a follow-up period of 5 years at least. The rate of survival for 5 years was 53.1 % and for 10 years 30.2 %. Only 33 patients were free of disease. 74.2 % of patients with recurrences died in relation to ITAC. As expected, tumors of T4-category had the worst prognosis. The mucus content of a tumor was the most important histological parameter. Endonasal methods of surgery had no more positive survival rates after 5 years. An effect of radiotherapy has to be in discussion. The high incidence of tumor recurrences requires control examinations consistently.
