Brachytherapy of squamous cell carcinoma of the nasal vestibule.

From 1985 to 1994, 23 patients with squamous cell carcinoma of the nasal vestibule were treated by brachytherapy. The TNM stage was as follows: T1N0 (9 patients), T2N0 (11 patients) and T4N0 (3 patients). Four patients had primary surgery and postoperative brachytherapy, whereas 12 patients had brachytherapy alone and 7 had tele- and brachytherapy in combination. For brachytherapy, the plastic tube technique was used. With the exception of one patient with a partial response, complete response was obtained in all patients. Two patients relapsed: one (T4N0) locally after 5 months and one (T2N0) regionally after 12 months. Both are alive and with no evidence of disease after salvage surgery. For early stage carcinoma (T1, T2) of the nasal vestibule, brachytherapy is a safe treatment yielding a high grade of local control and with good cosmetic results.
