摘要
目的:分析胸腹部肿瘤患者放射治疗依从性的影响因素及对摆位误差的影响。方法:利用自制依从性评分表对我院2021年03月至2022年06月放疗的胸腹部肿瘤患者进行调查,根据评分分为A组(依从得分≥12分)、B组(依从得分<12分),分别随机抽取25例患者。利用EPID每周为患者拍摄体位验证片,与最初计划系统生成DRR图对比计算摆位误差。比较分析两组患者摆位误差大小。结果:在左右(X)、头脚(Y)、前后(Z)三个方向,A组误差均小于B组(P<0.05);组内头脚(Y)方向误差大于左右(X)和前后(Z)方向(P<0.05);组内左右(X)和前后(Z)方向差异无统计学意义(P>0.05);随着治疗时间推进,B组在三个方向上误差呈减小趋势(P<0.05),A组变化无统计学差异(P>0.05)。结论:胸腹部肿瘤患者放射治疗依从性越好摆位误差越小,依从性差摆位误差较大的患者随着治疗时间推进误差逐渐减小,其值接近依从性好的患者。为了提高胸腹部肿瘤患者放射治疗效果,临床应采取相应措施,提升治疗依从性,减少摆位误差。
Objective:To analyze the influence factors of radiotherapy compliance in patients with thoracic and abdominal tumors and its effect on setup errors.Methods:Patients with thoracic or abdominal tumors receiving radiotherapy in our hospital from March 2021 to June 2022 were investigated by using self-made compliance rating table,and were divided into group A(compliance score≥12)and group B(compliance score<12),and 25 patients were randomly selected respectively.The EPID was used to take position verification films for patients every week,and the setup errors was calculated by comparing with the DRR images generated by the treatment planning system.The size of setup errors between the two groups was compared and analyzed.Results:The setup errors of group A was smaller than that of group B in left and right(X),head and foot(Y),front and back(Z)directions(P<0.05).The setup errors in the direction of the head and foot(Y)was greater than that in the direction of left and right(X)and the direction of front and back(Z)(P<0.05).There was no significant difference in X direction and Z direction(P>0.05).With the advance of treatment time,the setup errors in three directions showed a decreasing trend in the group B(P<0.05),while there was no statistical difference in the group A(P>0.05).Conclusion:For patients with thoracic and abdominal tumors,the better the radiotherapy compliance the less the setup errors.The setup errors of patients with poor compliance decreased gradually with the treatment time,and the values were close to those of patients with good compliance.In order to improve the effect of radiotherapy for patients with thoracic and abdominal tumors,effective measures should be taken to improve treatment compliance and reduce the setup errors.
