[125I seed implant brachytherapy of recurrent parotid gland malignant tumor].

Objective: To investigate the efficacy of radioactive seeds for the treatment of recurrence malignant parotid gland tumors.

Methods: Thirty-three patients with recurrence malignant parotid gland tumor treated by radioactive seeds were retrospectively reviewed. Three patients received implanted radioactive seeds alone. Thirty patients underwent both tumor resection and radioactive seeds implanting. The patients were followed up for 1041 months.

Results: All three patients receiving implanted radioactive seeds alone achieved CR Twenty-four patients treated by operation and radioactive seeds implanting had no local recurrence. The overall local control rate was 88%. The facial nerves were preserved in thirteen of fifteen patients without facial nerve palsy before treatment, and the facial nerve functioned well after operation. Four patients showed slight radiotherapeutic side effect.

Conclusions: Radioactive seeds implanting combined with operation or implanting radioactive seeds alone for the treatment of recurrent malignant parotid gland tumors could get good local control and treatment effects.
