选取我院2008年2月~2011年2月收治的64例食管癌患者,根据治疗方法不同将其分为对照组30例和观察组34例。对照组行三维立体适形放疗治疗,观察组行三维适形调强放疗治疗,对比两组治疗效果及副作用。结果观察组靶区适合度指数显著高于对照组,靶区剂量不均匀指数HI显著低于对照组,放疗副作用发生率显著低于对照组,且3年生存率显著高于对照组(P<0.05)。与三维立体适形放疗相比,调强放射可促使食管癌患者靶区剂量分布更为均匀,同时可给予患者脊髓有效保护,有利于降低患者放疗副作用的发生,值得在临床中推广。
The 64 patients with esophageal cancer admitted to our hospital from February 2008 to February 2011 were selected and divided into a control group of 30 patients and an observation group of 34 patients according to different treatment methods. The control group was treated with three-dimensional conformal radiotherapy. The observation group was treated with three-dimensional conformal intensity modulated radiation therapy. The treatment effects and side effects of the two groups were compared. Results In the observation group, the fitness index of the target area was significantly higher than that of the control group, and the target area uneven index HI was significantly lower than the control group. The incidence of side effects of radiotherapy was significantly lower than that of the control group, and the 3-year survival rate was significantly higher than that of the control group (P< 0.05). Compared with three-dimensional conformal radiotherapy, intensity-modulated radiation can promote even more uniform dose distribution in esophageal cancer patients and can effectively protect patients’ spinal cord, which is beneficial to reduce the occurrence of side effects of radiotherapy. It is worth promoting in clinical practice.
