Radiofrequency Ablation Is Low Invasive and Effective in Treat Pleomorphic Adenoma in Trachea Without Recurrence for At Least Five Years.

The authors reported 6 patients of pleomophic adenoma in trachea in patients (57 ± 3.6 years old). Swellings in trachea (2 ± 0.85 cm) were revealed by computed tomography and bronchoscopy. All swellings were removed successfully using radiofrequency ablation through flexible bronchoscopy. Histopathological examinations of tumor specimens confirmed their diagnosis of pleomorphic adenoma. No complication nor tumor recurrences were reported throughout the 5-year postoperative follow-up period in each patient which indicate good prognosis. The authors here report an effect but mini-invasive approach to treat rare trachea tumor and demonstrate a way of successful treatment using a mini-invasive way. Compared with other treating procedures, the authors consider radiofrequency ablation is of low invasion with the consequence of cure all treated patients of pleomorphic adenoma in trachea.
