【摘要】：目的在满足靶区及危及器官剂量要求的前提下,该研究以5个射野来进行调强放射治疗(IMRI)计划制订,从而达到以尽可能少的射野数目进行鼻咽癌的IMRI。方法通过对本院鼻咽癌患者放疗计划的对比分析,以0°、75°、125°、225°、285°方案进行布野,并以该布野方案同前五野、后五野、五野均分3种方案进行比较,对最终结果进行统计学分析。结果在靶区最大剂量(Dmax)和最小剂量(Dmin)上,4种布野方案差异无统计学意义(P0.05);在靶区D95、平均剂量(Dmean)及危及器官的剂量上,4种布野方案差异有统计学意义(P0.05)。结论综合比较4种布野方案在靶区、危及器官剂量分布,以0°、75°、125°、225°、285°方案布野时,能够得出更优的结果,该布野方案可实现本地区鼻咽癌患者的IMRI。
[Abstract]:Objective on the premise of meeting the requirements of target area and the dose of the organ at risk, the project of IMRI (IMRI) with 5 fields for intensity modulated radiotherapy (IMRI) was formulated, so as to achieve the IMRI of nasopharyngeal carcinoma (NPC) with as few fields as possible. Methods by comparing and analyzing the radiotherapy plan of nasopharyngeal carcinoma patients in our hospital, we used 0 掳75 掳75 掳125 掳125 掳225 掳tio 285 掳plan to arrange the field, and compared this scheme with the first five fields, the back five fields and the five fields equally. The final results were statistically analyzed. Results there was no significant difference between the maximum dose (Dmax) and the minimum dose (Dmin) of the four collocation schemes in target area (P 0.05), but there were significant differences among the four schemes in the target area (D95, mean dose, Dmean) and the dose of dangerous organs (P 0.05). Conclusion the dose distribution of organs is endangered by comparing the four collocation schemes in the target area, and the better results can be obtained by using the 0 掳~ 75 掳~ 125 掳~ 125 掳~ 225 掳~ 285 掳scheme. This scheme can realize the IMRI of nasopharyngeal carcinoma patients in our area.
