摘要
目的探讨调强放疗(IMRT)与三维适形放疗(3D-CRT)治疗局部晚期鼻咽癌的毒副作用及治疗效果。方法将120例局部晚期鼻咽癌患者随机分为观察组与对照组,每组60例。观察组采用调强适形放疗,对照组采用三维适形放疗。结果 2组随访时间、生存率及复发率差异无统计学意义(P>0.05)。随着时间延长,对照组中耳炎发生率增高速度明显高于观察组(P<0.05);观察组口腔毒副作用占46.67%,消化系统毒副作用占36.67%,血液系统毒副作用占10.00%,皮肤毒副作用占70.00%。对照组口腔毒副作用占56.67%,消化系统毒副作用占46.67%,血液系统毒副作用占16.67%,皮肤毒副作用占90.00%。由于样本量限制,2组未见统计学差异(P>0.05)。结论 IMRT与3D-CRT相比,效果相当,但毒副作用相对较小,需要进一步大样本验证。
Objective To investigate the side effects and therapeutic effect of intensity modulated radiotherapy ( IMRT) and three-dimensional conformal radiotherapy (3D-CRT) in the treatment of locally advanced nasopharyngeal carcinoma .Meth-ods 120 patients with locally advanced nasopharyngeal carcinoma were randomly divided into the observation group and the con -trol group .The observation group was treated with IMRT ,and the control group was treated with radiotherapy .Results There was no significant difference in the follow-up time,survival rate and recurrence rate between the 2 groups(P〉0.05).In the control group,the incidence rate of otitis was significantly higher than that in the observation group (P〈0.05).Side effects accounted for 46.67%,digestive system side effects accounted for 36.67%,the blood system side effects accounted for 10.00%,skin side effects accounted for 70.00%.56.67%of the oral toxicity in the control group ,46.67%in the digestive system,16.67%in the blood system and 90.00% in the skin side effects.There was no statistically significant difference between the 2 groups(P〉0.05) because of the limited sample size.Conclusion Compared with 3D-CRT,IMRT has the same effect,but the side effect is relatively small .
