34例上颌窦癌加速超分割根治放疗后残存癌处理分析

Analysis of 34 patiensts with residual maillary sinus carcinoma treated by whole course accelerate hyper-fractionated radiothrapy

目的 探讨上颌窦癌加速超分割根治放疗后残存癌的处理。方法 34例Ⅲ期上颌窦癌加速超分割根治放疗 ,2次 /日 ,1 5GY/次 ,间隔 6小时以上 ,DT78GY ,放疗后全部病例病变残存 ,放疗后 1、3、6、12月CT检查上颌窦病变。结果 放疗后 1、3、6、12月CT检查CR分别为 3/ 34、11/ 34、2 7/ 34、2 9/ 34。 2年内上颌窦癌的局部复发率分别为鳞癌 7 7% (1/ 13)、腺样囊性癌为 13 3% (2 / 15 )腺癌为 6 6 7% (4/ 6 )。结论 对晚期上颌窦癌加速超分割根治放疗后残存灶 ,依据CT检查 。

ohsective To ovserve the efficacy of the residual disease of maxillary sinus carcinooma patient rteated by whole course accelerate hyper fractionated radiotherapy materials Methods From march 1996 to December 2002,34 stage Ⅲ patients with maxillary sinus carcinoma were treated by whole course accelerate hyper-fractionated radiotherapy with a minimum inter fraction interval of 6 hours at 1.5GY per fraction,twice per day D T 78GY.All the patient treated by the whole course accelerate hyper-fractionated radiothrapy had residual lesion.They were followed up by CT examination for 1?2?6?12 month Result Depression rates of residual maxillary sinus carcinoma patient treated by whole course accelerate hyper-fractionated radiotherapy with CT examination for1,3,6,12 month were 8 8%,32 4%,61 8%,85%,local recurrent rates were 7 7%?13 3%?66 7%,among the squmous cell carcinoma adenocarcinoma.adenoid cystic carcinoma in two years after radiotherapy.Comclusion .The treatment of residual maxillary carcinoma treated by whole course accelerated radiotherapy depends on residual lesion depression by CT examination.
