Abstract

PURPOSE: Radiation treatment of sinonasal malignancies is a challenging task due to proximity to critical structures of the head and neck and skull base. Local tumor control is highly dose-dependent, but dose application is limited due to accompanying toxicity and dose constraints. To evaluate the toxicity and efficacy of combined radiation treatment with intensity-modulated radiation therapy (IMRT) and carbon ion boost, we conducted a prospective phase 2 IMRT-Heidelberg Ion-Beam Therapy Sinonasal Tumors (HIT-SNT) trial. - METHODS AND MATERIALS: Between 2011 and 2019, we treated 35 patients with histologically proven, incompletely resected or inoperable adeno- (51%) or squamous cell carcinoma (49%) of the paranasal sinuses with combined IMRT (50 Gy) and carbon ion boost (24 Gy relative biologic effectiveness) to a total dose of 74 Gy. - RESULTS: Acute mucositis Common Terminology Criteria for Adverse Events (CTCAE) grade 3 occurred in 12% of patients (n = 4) and was accompanied by odynophagia CTCAE grade 3. Except for 1 case of grade 3 weight loss, no other acute high-grade toxicity (grade 3-4) was observed. In a small patient cohort of 15 patients eligible for long-term follow-up we have seen no high-grade (grade ≥3) long-term side effects 2 years after radiation therapy. None of these patients suffered from therapy-associated vision or hearing loss. Secondary endpoints were 2-year overall survival, 2-year local progression-free survival, 2-year progression-free survival, and 2-year metastases-free survival with 79.4%, 61.8%, 61.8%, and 64.8%, respectively. - CONCLUSIONS: To our knowledge, this is the first prospective data on toxicity and outcome of bimodal radiation therapy for the rare entity of sinonasal malignancies. Our study shows a low rate of CTCAE-reported acute toxicity with reasonable tumor control and survival rates after bimodal radiation therapy, which therefore remains a therapy approach to be further evaluated.
