目的 分析腮腺恶性肿瘤术后放疗的疗效及影响预后因素。方法 回顾1990年1月～1995年1月我科收治的36例术后患者,采用~(60)Co和电子线照射,有淋巴结转移者包括同侧颈淋巴引流区,剂量为40～60Gy/4～6周。结果 36例腮腺恶性肿瘤术后病人行放疗5年生存率为69.4％。病理类型以腺样囊腺癌、泡状细胞癌、粘液表皮样癌预后好。术后放疗剂量<50Gy,5年生存率为46.2％;≥50Gy者5年生存率为82.6％。结论 对腮腺恶性肿瘤病人应采用手术加放疗的综合治疗疗效最佳。
Objective To analyze the curative effect and postoperative prognostic factors of postoperative radiotherapy for parotid malignant tumors. Methods From January 1990 to January 1995, 36 cases of postoperative patients admitted to our department were treated with ~ (60) Co and electron beam irradiation. The patients with lymph node metastasis included the ipsilateral cervical lymphatic drainage area at a dosage of 40-60 Gy / 4 to 6 weeks. Results 36 patients with parotid malignant tumor after radiotherapy 5-year survival rate was 69.4%. Pathological types of adenoid cystadenocarcinoma, vesicular cell carcinoma, mucoepidermoid carcinoma prognosis. Postoperative radiotherapy dose <50Gy, 5-year survival rate was 46.2%; 5-year survival rate of ≥ 50Gy 82.6%. Conclusions The comprehensive treatment of parotid malignant tumor patients should be treated with surgery plus radiotherapy best.
