Brief summary
The IMRT-HIT-SNT trial is a prospective, mono-centric, phase II trial evaluating toxicity and efficacy in the combined treatment with intensity-modulated radiation therapy (IMRT) and carbon ion (C12) boost. Primary endpoint is mucositis ≥ CTC°3, secondary endpoints are local control, disease-free survival, overall survival, and toxicity. Planned accrual of the trial includes 36 patients with histologically proven (≥R1-resected or inoperable) sinonasal malignancies.
Detailed description
Local control in sinonasal malignancies is dose dependent. However, dose escalation at acceptable toxicity is technically demanding even with modern radiotherapy techniques. Raster-scanned carbon ion therapy with highly conformal dose distributions may allow higher doses at comparable or reduced side-effects. Methods/ design: The IMRT-HIT-SNT trial is a prospective, mono-centric, phase II trial evaluating toxicity in the combined treatment with intensity-modulated radiation therapy (IMRT) and carbon ion (C12) boost in 36 patients with histologically proven (≥R1-resected or inoperable) adeno-/ or squamous cell carcinoma of the nasal cavity or paransal sinuses. Patients receive 24 GyE carbon ions (8 fractions) and IMRT (2.0 Gy/ fraction). Study objectives: Incidence of mucositis ≥ CTC°3 will be assessed as the primary endpoint of the trial, local control, disease-free survival, overall survival, and toxicity (incl. mucositis CTC °I-II and late toxicity at 2 years post RT)are secondary endpoints.
Interventions
8 fractions carbon ion (8 x 3 GyE C12) therapy followed by 25 fractions of IMRT corresponding to a total dose of approximately 74 GyE. Treatment duration is approximately 61/2-7 weeks
