BACKGROUND: The purpose of this study was to evaluate outcome and toxicity profile after primary brachytherapy for squamous cell carcinoma of the nasal vestibule.
METHODS: A retrospective study was conducted for patients with Wang classification T1 to 2 cN0 squamous cell carcinoma of the nasal vestibule who received primary treatment with brachytherapy between 1992 and 2010. Tumor control, acute skin, mucosal, and late cartilage toxicity were scored.
RESULTS: Of 60 patients (T1, 50; T2, 10), 38 were treated with an interstitial implant and 22 by a mold technique. The 3-year local, regional, and locoregional control rates were 91%, 93%, and 84%, respectively. Tumor diameter <1.5 cm resulted in a better local (p = .02) and regional (p = .05) control. The cumulative incidence of moist skin desquamation and confluent mucositis was 64% and 82%, respectively. The actuarial incidence of chondritis and/or chondronecrosis was 19%.
CONCLUSION: Primary brachytherapy for Wang T1 to 2 squamous cell carcinoma of the nasal vestibule offers excellent tumor control rates with acceptable toxicity and preservation of anatomy.
