摘要
目的 :回顾分析腮腺癌术后放射治疗的作用及影响预后的因素。方法 :3 3例经病理证实的腮腺癌 (Ⅰ期 2例 ,Ⅱ期 6例 ,Ⅲ期 15例 ,Ⅳ期 10例 )术后采用 60Coγ线和直线加速器电子束进行放射治疗 ,并随访 >5年。结果 :全组 5年生存率为 72 7% ,5年局控率为87 9%。术后放疗以 5 0～ 60Gy剂量组疗效较好 ,5年生存率为94 4%。病理类型中腺癌、鳞癌及未分化癌预后较差。结论 :腮腺癌应提倡手术加放疗的综合治疗 ,放疗采用光子束和电子束混合线照射 ,肿瘤剂量以 5 0～
OBJECTIVE:To analyse the role of postoperative radiotherapy for parotid gland carcinoma and the prognostic factors retrospectively.METHODS:Thirty three postoperated patients with parotid gland carcinoma (2 in stage Ⅰ,6 in stageⅡ,15 in stage Ⅲ,10 in stage Ⅳ) were radiated by 60 Co γ rays and linear accelerator E rays.All patients were proven by pathology.Follow up was over five years.RESULTS:The 5 year overall survival rates and local control rates were 72 7% and 87 9% for all patients, respectively.The group given dose 50-60 Gy had better prognosis and their 5 year overall survival rates were 94 4%.Poor prognosis was observed in the cases with the pathological classification of adenocarcinoma,squamous cell carcinoma and undifferentiated carcinoma.CONCLUSIONS:It is recommended that treatment for parotid gland carcinoma should be combined with surgery and radiation.The patients who are given dose 50-60 Gy by the mixed photon electron beam can get better prognosis.Radical surgical operation and pathological type are the important prognostic factors.
