摘要:目的 探討口腔頜面部鱗癌經125I放射性粒子治療后的近期療效。方法 選擇2015年6月~2016年8月在徐州醫科大學口腔科就診的口腔頜面部鱗癌患者13例,以放射性粒子定向植入治療系統(treatment planning system,TPS)為參考,確定植入125I放射性粒子的粒子數、布源情況及進針方向。粒子間隔0.5~1.0 cm,活度為10.4~37.0 MBq。術后觀察治療效果及不良反應。結果 全部患者手術過程順利,術后復查CT未見粒子移位、丟失等。隨訪觀察4~20個月,治愈有效率為69.23%,術后未出現嚴重放療并發癥。結論 125I放射性粒子植入適用于口腔頜面部鱗癌患者的治療,具有組織損傷小,安全可靠,能提高患者生存率并有效保存口咽功能。

Abstract:Objective To investigate the curative effect of 125I radioactive particles after treatment of oral maxillofacial squamous cell carcinoma. Methods From June 2015~2016 year in August 13 cases in the Department of Stomatology,Xuzhou Medical University oral and maxillofacial squamous cell carcinoma patients with radioactive particles implantation in the treatment of directional system(treatment planning system,TPS)as a reference to determine the number of implantation of 125I radioactive particles,cloth the source and the needle direction.The particle spacing of 0.5~1.0 cm,the activity of 10.4~37.0 MBq.Postoperative therapeutic effects and adverse reactions were observed.Results All patients underwent a successful operation,and there was no particle displacement or loss after the operation.The follow-up observation was 4~20 months, the effective rate was 69.23%,and there was no severe complication of radiotherapy after CT.Conclusion 125I radioactive particle implantation is suitable for the treatment of oral and maxillofacial squamous cell carcinoma with little tissue damage,safe and reliable,can improve the survival rate of patients,and effectively preserve the oropharynx function.

鱗狀細胞癌是口腔頜面部最常見的惡性腫瘤之一,占口腔頜面部惡性腫瘤的40%,是排名第六的常見腫瘤[1]。由于口腔頜面部包含許多重要的組織器官,神經血管等解剖結構關系復雜,使得外科手術無法做到根治性切除。另外,一部分患者因年齡大、體質差,無法耐受手術的創傷。125I放射性粒子治療以其創傷小,患者術后生存質量高的優點,逐漸成為口腔頜面部惡性腫瘤治療尤其是鱗癌治療的重要方法[2-3]。本文總結我科2015年6月~2016年8月125I放射性粒子頜面部鱗癌患者13例,現報道如下:
1 資料與方法
1.1一般資料 選擇2015年6月~2016年8月就診于我科的口腔頜面部惡性腫瘤患者,均經活體組織病理證實為口腔頜面部鱗狀細胞癌,共13例,男8例,女5例,年齡在56~86歲,平均年齡72.3歲。13例患者因身體狀況無法耐受手術或因手術影響生存質量而拒絕手術治療。……
