【摘要】：目的探究强调放疗与适形放疗计划在诊治该病过程中的计量学对比。方法回顾性分析该院2013年10月11日-2015年10月10日84例诊治中晚期食管癌患者的治疗情况,将其随机分为强调组和适形组,每组患者各42例,测定并比较两组患者预防照射区和肿瘤区照射剂量参数及体积参数。结果强调组患者在预防照射区D_(100)、D_(95)、V_(105)及HI值均优于适形组患者(P0.05);两组患者在预防照射区V_(100)、V_(95)值基本一致(P0.05);强调组患者在肿瘤区V_(100)、HI值均优于适形组患者(P0.05);两组患者在肿瘤区D_(100)、D_(95)、V_(105)及V_(95)值基本一致(P0.05)。结论强调放疗较适形放疗计划使患者的预防照射区和肿瘤区均可获得较好的照射剂量,且患者病灶部位可获得更高的生物等效剂量,适于临床推广使用。
[Abstract]:Objective to explore the metrological comparison between radiotherapy and conformal radiotherapy in the diagnosis and treatment of the disease. Methods 84 patients with advanced esophageal carcinoma from October 11th 2013 to October 10th 2015 in our hospital were retrospectively analyzed. They were randomly divided into emphasis group and conformal group with 42 patients in each group. The dose parameters and volume parameters of the two groups were measured and compared. Results it was emphasized that the values of the two groups were superior to those of the conformal group (P 0.05) and that of the patients of the two groups in the prevention area of radiation exposure, and the values of the two groups were basically superior to those of the conformal group (P < 0.05) in the prevention area of radiation exposure, and the value of the patients in the two groups was basically higher than that of the patients in the prevention area of radiation exposure. It was emphasized that the HI value of the patients in the tumor area was higher than that in the conformal group, and the values of the two groups were basically consistent with the values of P0.05in the tumor area. Conclusion it is important to emphasize that the plan of radiotherapy is more conformal than that of the conformal radiotherapy plan so that the preventive radiation area and the tumor area can be obtained in both the prevention area and the tumor area. A better dose of radiation, Higher bioequivalent dose can be obtained at the lesion site, which is suitable for clinical application.
