ABSTRACT
Objective To evaluate the efficacy of 125Ⅰ brachytherapy alone for the treatment of recurrent parotid gland carcinoma.Methods Recurrent parotid gland carcinoma patients (n =24) treated by 125Ⅰ brachytherapy alone between 2006 and 2013 at Peking University Hospital of Stomatology were enrolled in this retrospective study.All patients underwent surgery or radiotherapy.The local control rate,survival rate,and side effects were evaluated.Results The median follow-up time was 21 months (range,4-59 months).Among the 24 patients,6 had local failure and 10 died during the follow-up period.The 1-and 3-year overall survival rates,progression-free survival rates,local control rates were 74.8％ and 39.3％,74.8％ and 31.5％,82.0％ and 69.4％,respectively.No grade 3 or over radiation injury was found.Conclusions 125Ⅰ seed brachytherapy alone could provide an ahernative treatment method for inoperable recurrent parotid gland carcinoma patients.
ABSTRACT
Cutaneous metastasis from parotid gland carcinoma is very rare and there have been no re-ports in Korean literatures. Furthermore, it can often manifest as inflammatory type of skin metastasis and mimic a radiodermatitis. We report a case of a 31-year-old Korean man with cutaneous metastasis originated from parotid gland mucoepidermoid carcoinoma which mimicked clinically a radiodermatitis.

Objective: To evaluate the efficacy of postoperative radiotherapy in the treatment of parotid gland carcinoma. Methods: Eighty-six postoperated patients with parotid gland carcinoma( 7 in stage Ⅰ, 28 in stage Ⅱ, 33 in stage Ⅲ and 18 in stage Ⅳ) were radiated by 60Co ?-ray or linear accelerator X-ray combined with electron beam. All patients were diagnosed by pathology and followed up for more than 5 years. Results: The five year survival rate and the local control rate were 73.3% and 87.2% respectively. Poor prognosis was observed in the cases with the neoplastic classification of undifferentiated carcinoma, sequamous cell carcinoma and malignant pleomorphic adenoma, but the better prognosis was obtained in the cases with acinic cell carcinoma and mucoepidermoid carcinoma. Poor prognosis was observed in the cases with stage Ⅲ and Ⅳ of clinical stage. Radiotherapy undertaken in 2 weeks after surgical operation gave higher 5- year survival ratio( 83.8%). The group given 51～60 Gy radiation showed 82.9% of five- year survival rate. Conclusion: The combination of surgery with radiation is effective in the treatment of parotid gland carcinoma.Radiation of 51～60 Gy 2 weeks after operation may result in better prognosis. Neoplastic type and clinical stage are important factors for prognosis.
