摘要
目的:探讨立体定向放射治疗对胰腺癌的治疗作用。方法:对112例胰腺癌患者实施立体定向伽玛刀治疗,50%剂量曲线DT3.2-3.5Gy,8-10次,3f/w。放疗后随访。结果:患者治疗后3个月至18个月复查CT或MRI提示,胰腺肿瘤区均有所缩小,肿瘤局控率(CR+PR)87%(92/106),82例患者腰背部疼痛缓解98%(81/82)。13例不完全梗阻性黄疸症状全部消失,缓解率100%。结论:对于胰腺肿瘤患者,采用立体定向精确放射治疗后可以延长生存期,提高生活质量。
Objective:To discuss the effect of stereotactic conformal on pancreatic cancer. Methods: One hundred and twelve cases with pancreatic cancer were treated by stereotactic conformal radiotherapy. The 50% dose curves were selected in γ - knife and target dose were from 3.2Gy to 3.5Gy each time ,three times a week for 8 - 10 times totally. Results: Three months to eighteen months after treatment,the tumor volume of all cases diminished and the overall response rate( CR + PR) reached 87% ,with the pain in belly remitting rate reaching 98% and the jaundice of 13 cases disappearing. Conclusion: The stereotactic conformal radiotherapy can be used in practice for the pancreatic cancer, increase patients' survival time and improve the quality of life.
