Abstract

Objective Our objective was to compare the long-term outcomes of endoscopic resection versus open surgery in combination with radiotherapy for locally advanced sinonasal malignancies (SNMs).

Methods Data for continuous patients with sinonasal squamous cell carcinoma and adenocarcinoma who received surgery (endoscopic or open surgery) combined with radiotherapy in our center between January 1999 and December 2016 were retrospectively reviewed. A 1:1 matching with propensity scores was performed. Overall survival (OS), progression-free survival (PFS), and local recurrence rate (LRR) were evaluated.

Results We identified 267 eligible patients, 90 of whom were included after matching: 45 patients in the endoscopy group and 45 in the open group. The median follow-up time was 87 months. In the endoscopic group, 84.4% of patients received intensity-modulated radiotherapy (IMRT), with a mean gross tumor volume (GTV) dose of 68.28 Gy; in the open surgery group, 64.4% of patients received IMRT, with a mean GTV dose of 64 Gy. The 5-year OS, PFS, and LRR were 69.9, 58.6, and 24.5% in the endoscopic group and 64.6, 54.4, and 31.8% in the open surgery group, respectively. Multivariable regression analysis revealed that the surgical approach was not associated with lower OS, PFS, or LRR. The overall postoperative complications were 13% in the endoscopic group, while 21.7% in the open group.

Conclusion For patients with locally advanced SNMs, minimally invasive endoscopic resection, in combination with a higher radiation dose and new radiation techniques such as IMRT, yields survival outcomes similar to those of open surgery in combination with radiotherapy.
