Acinic cell carcinoma--Plymouth's experience with postoperative radical radiotherapy.

Acinic cell carcinoma represents 2.5% of all parotid neoplasms. Experience in its management is limited and its initial clinical diagnosis may be incorrect. This paper examines six patients who received less than ideal primary surgical care. Duration of follow up ranges from 1.25 years to 10.5 years, mean 6.7 years. Prophylactic postoperative radiotherapy appears to be of marked benefit in preventing recurrence and cervical node metastases.
