OBJECTIVES/HYPOTHESIS: Evaluation of treatment results of orthovoltage X-rays for a selection of previously untreated favorable basal cell carcinomas (BCC) in the head and neck area concerning local control, cosmetic and functional outcome, and toxicity profile. METHODS: A consecutive series of patients with primarily treated BCCs who were irradiated by means of orthovoltage X-rays in the Netherlands Cancer Institute in Amsterdam between January 2000 and February 2015 were retrospectively evaluated. RESULTS: Two hundred fifty-three BCCs in 232 patients were primarily treated with orthovoltage X-rays. The local control rates at 1, 3, and 5 years for this selection of basal cell carcinomas were 98.9%, 97.5%, and 96.3%, respectively. Tumor size was the only significant predictor for local control because BCCs < 20 mm had a significantly higher 5-year local control rate than lesions ≥ 20 mm (96.8% vs. 89.4%, P = 0.041). Acute toxicity healed spontaneously without medical intervention, and late toxicity rates were low. Functional impairments were negligible, and the cosmetic outcome was excellent. CONCLUSION: Orthovoltage therapy for well-selected favorable BCCs in the head and neck area resulted in excellent local control rates, a low toxicity profile, and apparently satisfactory functional and cosmetic outcomes. Orthovoltage irradiation is a good alternative for surgery for BCCs with favorable histologic prognosis at locations that are at risk for postoperative functional or cosmetic changes, such as the nose or canthus. LEVEL OF EVIDENCE: 4. Laryngoscope, 126:1796-1802, 2016.
