Abstract Background The purpose of this study was to describe the pathology of the different compartments in endoscopic resection of nasal intestinal‐type adenocarcinomas (ITACs) and its relationships with oncologic outcomes. Methods This retrospective study included all patients endoscopically operated for nasal ITACs, followed by radiotherapy in the majority of cases, between 2004 and 2014. The surgery systematically separated 3 compartments: ethmoid lateral mass, olfactory cleft, and anterior cranial fossa (in cases with skull‐base invasion) to analyze their pathological “focal” or “massive” invasion by the tumor. Results Sixty‐seven patients (aged 69.2 ± 9.8 years) were included. Twenty‐nine patients (43.3%) had only pathological focal invasion. At 61.0 ± 41.7 months of mean follow‐up, the recurrence rates were 34.2% in the group with massive invasion and 10.3% in the group with focal invasion ( P = .023). The disease‐specific death rate had a tendency to be higher in the group with massive invasion (23.7% vs 6.9% for the group with focal invasion; P = .097). By Kaplan‐Meier analysis, the 5‐year disease‐specific survival rate was better in the group with focal invasion than the group with massive invasion ( P = .01). The 5‐year overall survival was not different between the 2 groups (47.4% and 65.5% for focal invasion and massive invasion respectively; P = .14). Conclusion Compartmentalized endoscopic resection, combined with postoperative radiotherapy, is one way to operate on nasal ITACs with good oncologic outcomes.
