Conclusion: In our experience, the prognosis for parotid gland acinic cell carcinoma (AciCC) is good. Surgery alone would be sufficient in early-stage tumor. Postoperative adjuvant treatment in advanced-stage patients or those with positive resection margins usually gives satisfactory control of the disease. Objectives: AciCC is a rare tumor in parotid gland malignancy. The aim of this study was to retrospectively analyze the experience in our hospital in treating this malignancy. Methods: Twenty-five patients with AciCC diagnosed from 1983 to 2007 at the Chang Gung Memorial Hospital were retrospectively reviewed. Results: Thirteen male and 12 female patients ranged in age from 16 to 84 years (mean 37.5 years) at the time of diagnosis. Most patients (92%) presented with symptoms of infra-auricular mass. The tumor stage distributions of the patients were 24%, 44%, 28%, and 4% for stages I, II, III, and IV, respectively. Thirteen patients underwent superficial parotidectomy and 12 patients underwent total parotidectomy. Four patients had positive resection margins. Ten patients had surgery and postoperative radiotherapy; one received surgery and postoperative chemo/radiotherapy. The 10-year disease-free and overall actuarial survivals were both 84% in a mean follow-up of 75.8 months. [ABSTRACT FROM AUTHOR]
