Objective To investigate the effects of multimedia information technologies on precision radiotherapy of head and neck malignant tumors (HNT).
Methods A total of 96 patients with HNT recruited from 2016 to 2019 were randomly assignedto group A and group B with the same planning methodand therapists/technicians. Conventional and multimedia information technologies were respectively used in group A and group B for medical science popularization, individualized education, and doctor-patient communication before radiotherapy planning and positioning. Medical compliance, radiotherapy responses, setup errors, and machine occupancy time were investigated.
Results Medical compliance was significantly higher ( P < 0.05) in group A (96.5%) than in group B (73.8%). Skin acute radiation reaction was significantly lower ( P < 0.05) in group A than in group B. Three-dimensional absolute setup errors were 0.69 ± 0.29 mm, 0.97 ± 0.69 mm, and 0.79 ±0.47 mm in group A, which were significantly lower than 1.39 ± 0.81 mm, 1.87 ± 1.19 mm, and 2.50 ± 0.99 mm in group B ( P < 0.05). Traditional three-dimensional setup errors were 0.73 ± 0.39 mm, 0.51 ± 0.69 mm, and 0.74 ± 0.17 mm in group A, which were significantly lower than 1.32 ± 0.76 mm, 1.89 ± 1.21 mm, and 1.37 ± 0.57 mm in group B ( P < 0.05). Planning time was 145.15 ± 28.45 sin group A, which was significantly lower than 240.38 ± 50.45 sin group B ( P < 0.05). Positioning time was 115.15 ± 18.45 s in group A, which was significantly lower than 173.38 ± 24.45 sin group B ( P < 0.05).
Conclusion The application of multimedia information technologies inmedical science popularization, individualized education, and doctor-patient communication forpatients who received precision radiotherapy for HNT can significantly increase patient compliance, alleviate acute radiation reactions, reduce setup errors, and shorten the machine occupancy time of planning and positioning.
摘要: 目的 探讨多媒体信息技术对头颈部恶性肿瘤(head and neck malignant tumors, HNT)精确放疗的影响。 方法 选取2016—2019年HNT患者96例, 随机分为实验组A组和对照组B组, 同一固定体位方法、治疗医师及技 师, 分别应用多媒体信息技术、常规方法, 施行医学科普、个体化教育、医患沟通后放疗定位、摆位。调查医疗依从性、观察放疗反应、分析摆位误差、记录占机时间。 结果 依从性A组96.5% > B组73.8%, 差异有统计学意义 ( P < 0.05); 皮肤急性放射反应A组< B组, 差异有统计学意义 ( P < 0.05)。三维绝对摆位误差:A组(0.69 ± 0.29) mm、(0.97 ± 0.69) mm、(0.79 ± 0.47) mm < B 组(1.39 ± 0.81) mm、(1.87 ± 1.19) mm、(2.50 ± 0.99) mm, 差异有统计学意义( P < 0.05);三维传统摆位误差:A 组(0.73 ± 0.39) mm、(0.51 ± 0.69) mm、(0.74 ± 0.17) mm < B 组(1.32 ± 0.76) mm、(1.89 ± 1.21) mm、(1.37 ± 0.57) mm, 差异有统计学意义( P < 0.05)。定位占机时间 A 组(145.15 ± 28.45) s < B 组(240.38 ± 50.45) s, 差异有统计学意义 ( P < 0.05); 摆位占机时间A组(115.15 ± 18.45) s < B组(173.38 ± 24.45) s, 差异有统计学 意义( P < 0.05)。 结论 应用多媒体信息技术对HNT精确放疗患者施行医学科普、个体化教育、医患沟通, 可提高患 者依从性, 减轻急性放射反应, 降低摆位误差, 缩短定、摆位占机时间。
