Endoscopic resection and topical 5-Fluorouracil as an alternative treatment to craniofacial resection for the management of primary intestinal-type sinonasal adenocarcinoma.

Introduction. Intestinal-type adenocarcinoma of the sinonasal tract is very rare and is responsible for less than 4% of tumours of the sinuses. Craniofacial resection has been the mainstay of treatment for many years; however, techniques for endoscopic resection are constantly being developed. Discussion. The use of transnasal endoscopic resection (TER) and topical chemotherapy applications as an alternative to cranio-facial resection (CFR) is discussed. TER offers advantages over CFR in terms of fewer intra-operative complications and an improved cosmetic outcome. Survival and metastatic rates are similar between both procedures. Patients with locally invasive tumours are better managed with CFR. Topical applications of 5-Fluorouracil has been shown to be effective in increasing survival in patients with sino-nasal malignancy. Conclusion. Trans-nasal endoscopic resection and topical 5-Fluorouracil could potentially offer an acceptable alternative treatment to the standard of cranio-facial resection. This should be investigated in trials with a longer followup period than this paper in order to directly compare the two treatment modalities.
