Objective: To evaluate toxicity outcomes for head and neck squamous cell carcinoma (HNSCC) with an unknown primary treated with 3-dimensional conformal radiotherapy (3D-CRT) compared with intensity-modulated radiation therapy (IMRT).
Design: Retrospective review of records.
Setting: Medical College of Wisconsin Cancer Center.
Patients: Records were found for 27 patients treated with radiation therapy for HNSCC of an unknown primary from 1991 to 2004. Median follow-up after treatment was 32 months (range, 4-108 months).
