目的:比较分析食管癌调强放射治疗与三维适形放疗的效果。方法:选取2015年9月至2016年8月我院收治的110例食管癌患者进行研究,分为对照组和观察组,每组各55例。对照组采用三维适形放疗形式,观察组采用强调物理放疗计划,观察两组放疗情况。结果:预防照射区放疗方面,观察组要明显优于对照组,P<0.05,具有统计学意义;在肿瘤区情况方面,观察组的V100高于对照组,差异显著,P<0.05,具有统计学意义。结论:与三维适形放疗相比,调强放射治疗能够使得预防照射区和肿瘤区都可以得到理想的剂量分布,值得推广。
Objective: To comparatively analyze the effect of intensity-modulated radiation therapy and three-dimensional conformal radiotherapy in esophageal cancer. Methods: A total of 110 patients with esophageal cancer treated in our hospital from September 2015 to August 2016 were selected and divided into control group and observation group, with 55 cases in each group. The control group was treated with three-dimensional conformal radiotherapy, and the observation group emphasized the plan of physical radiotherapy to observe the radiotherapy condition of the two groups. Results: In the area of radiation prevention, the observation group was significantly better than the control group, P <0.05, with statistical significance; in the tumor area, the observation group V100 higher than the control group, the difference was significant, P <0.05, with statistics Significance of learning. CONCLUSIONS: Compared with three-dimensional conformal radiotherapy, IMRT can make the ideal radiation dose distribution in the irradiation prevention and tumor areas worthy of promotion.
