摘要 目的比较三维适形放射治疗(3D-CRT)与常规放疗非小细胞肺癌(NSCLC)时,放射所致食管损伤的出现时间、严重程度和临床症状持续时间的差异。方法89例NSCLC患者,男性59例,女性30例,中位年龄67岁(33~84岁),随机分为3D-CRT组(48例)和RT组(41例)。依据RTOC标准对食管损伤进行评价,分析两组患者食管损伤的出现时间、严重程度和症状持续时间的差异。结果3D-CRT组食管损伤发生率为20.83%,低于RT组的发生率41.46%,两组差异有统计学意义(P<0.05)。3D-CRT组食管损伤程度主要是1~2级,RT组则主要集中在2~3级,两组损伤程度差异无统计学意义(P>0.05)。RT组损伤发生较3D-CRT组早,两组间差异具有统计学意义(P<0.05)。RT组食管损伤持续时间要长于3D-CRT组,且两组间差异具有统计学意义(P<0.05)。结论在NSCLC放疗时,RT所致食管损伤的发生率高于3D-CRT,出现时间也早于3D-CRT,临床症状持续时间亦比3D-CRT要长。
