Long-term follow-up of 44 patients with adenocarcinoma of the nasal cavity and sinuses primarily treated with endoscopic resection followed by radiotherapy.

Abstract

Endoscopic resection followed by radiotherapy as primary treatment for adenocarcinoma of the sinuses is emerging as an alternative to open resection. A total of 44 patients primarily treated by an endoscopic approach followed by radiotherapy from 1992 to 2004 seen at our ENT-Department were analyzed for outcome and prognostic factors. Median follow-up was 61 months. Median follow-up of the patients alive at the end of the follow-up period was 100 months. For the 5-year follow-up, the overall survival, disease-specific survival, and recurrence-free survival were 63% (±7% SE), 82% (±6), and 60% (±8%), respectively. The overall survival, disease-specific survival, and recurrence-free survival after 100 months of follow-up were 53% (±8%), 72% (±9%), and 54% (±9%), respectively. Four factors significantly influenced the disease-specific survival. This study of a homogeneous cohort of patients with sinonasal adenocarcinoma treated by endoscopic resection and radiotherapy confirms that endoscopic resection is a valid alternative to open resection.
