Background Intestinal‐type adenocarcinoma (ITAC) is a rare and locally aggressive occupation‐related tumor. Currently, endoscopic‐assisted resection and advances in irradiation modalities (3D conformal radiotherapy/intensity‐modulated radiation therapy [IMRT]) are emerging as an alternative to traditional open surgery and conventional radiotherapy. Methods Retrospective analysis of 30 consecutive patients affected with sinonasal ITAC, primarily treated by an endoscopic approach followed by 3D conformal radiotherapy/IMRT at a single institution, from 2003 to 2010. Results The 5‐year overall survival (OS), disease‐specific survival (DSS), disease‐free survival (DFS), and recurrence‐free survival (RFS) were 72.7% ± 9.6%, 78% ± 9.5%, 67.9% ± 10.7%, and 69.2% ± 9.4%, respectively (mean follow‐up, 48 months). No major complications or serious toxicities were observed. Prognostic factors were stage of disease at diagnosis, development of recurrences, status of surgical margins, grading, tumoral pattern of growth, and proliferative index (Ki‐67). Conclusion The low morbidity of endoscopic approaches, the acceptable toxicity of modern irradiation modalities, and these promising survival rates, indicate that this treatment strategy might be considered a safe, minimally invasive, and maximally effective option for treating selected sinonasal ITAC. © 2014 Wiley Periodicals, Inc.
