目的：评价腮腺癌术后放射治疗的效果。方法：用６０Ｃｏ或直线加速器Ｘ线和电子束对１０６例腮腺癌术后患者进行放射治疗，并随访５年以上。结果：５年生存率７４．５％，肿瘤局部控制率８４．９％。术后放疗剂量以５１Ｇｙ～６０Ｇｙ疗效较好，５年生存率８１．５％，肿瘤局部控制率９３．４％。病理类型中，腺样囊性癌、粘液表皮样癌、腺泡细胞癌、乳头状囊性癌预后情况较好。结论：术后放疗可以显著提高腮腺癌患者的５年生存率。原发灶首次的彻底手术是提高疗效的重要因素
Objective: To evaluate the effect of postoperative radiotherapy for parotid gland cancer. Methods: Sixty-six patients with postoperative salivary gland cancer were treated with 60Co or linear accelerator X-ray and electron beam. The patients were followed up for more than 5 years. Results: The 5-year survival rate was 74.5%, and the local tumor control rate was 84.9%. Postoperative radiotherapy doses with 51Gy ~ 60Gy better efficacy, 5-year survival rate of 81.5%, local control rate of 93.4%. In the pathological type, the prognosis of adenoid cystic carcinoma, mucoepidermoid carcinoma, acinar cell carcinoma and papillary cystic carcinoma is better. Conclusion: Postoperative radiotherapy can significantly improve the 5-year survival rate of patients with parotid adenocarcinoma. Thorough surgery for primary lesions for the first time is an important factor in improving efficacy
