Objective/Purpose: To evaluate the preliminary results of perioperative endoscopy-guided brachytherapy (BT) in recurrent sinonasal and nasopharyngeal tumors already treated for their primary tumor with a full course of radiotherapy. Methods and Materials: Patients with recurrence and already treated with a previous full course of radiotherapy >65Gy who underwent BT from December 2010 to January 2014 were taken into account for this work. Macroscopic disease was resected by an endoscopic approach, and catheters for BT were endoscopically positioned and fixed at the same time on the surgical bed. Surgery was performed under electromagnetic navigation guidance. The irradiation dose was 30Gy in 12 fractions, 2.5Gy each, twice a day, in 6days. Results: We performed the endoscopy-guided BT 11 times in 9 patients; in two cases, no previous radiation therapy had been performed; and in one case, followup was too short to be considered. A total of 6 patients were eligible for the analysis. One patient underwent BT three times because of previous target margin recurrences. There were no immediate complications. The median and mean followups were 21 and 19months, respectively. The median V90 and V85% were 93% and 95%, respectively. In one case, we had a transient deficit of the VI cranial nerve (G3), and in another case, we diagnosed a noncomplicated osteonecrosis (G2). The median disease-free survival is 12months, and the median overall survival is 23months. Conclusions: The combination of endoscopy and BT seems to be a safe option for treating recurrent sinonasal and nasopharyngeal tumors.

Abstract

Objective/Purpose: To evaluate the preliminary results of perioperative endoscopy-guided brachytherapy (BT) in recurrent sinonasal and nasopharyngeal tumors already treated for their primary tumor with a full course of radiotherapy. Methods and Materials: Patients with recurrence and already treated with a previous full course of radiotherapy >65Gy who underwent BT from December 2010 to January 2014 were taken into account for this work. Macroscopic disease was resected by an endoscopic approach, and catheters for BT were endoscopically positioned and fixed at the same time on the surgical bed. Surgery was performed under electromagnetic navigation guidance. The irradiation dose was 30Gy in 12 fractions, 2.5Gy each, twice a day, in 6days. Results: We performed the endoscopy-guided BT 11 times in 9 patients; in two cases, no previous radiation therapy had been performed; and in one case, followup was too short to be considered. A total of 6 patients were eligible for the analysis. One patient underwent BT three times because of previous target margin recurrences. There were no immediate complications. The median and mean followups were 21 and 19months, respectively. The median V90 and V85% were 93% and 95%, respectively. In one case, we had a transient deficit of the VI cranial nerve (G3), and in another case, we diagnosed a noncomplicated osteonecrosis (G2). The median disease-free survival is 12months, and the median overall survival is 23months. Conclusions: The combination of endoscopy and BT seems to be a safe option for treating recurrent sinonasal and nasopharyngeal tumors.
