摘要
与 3D-CRT 组和 IMRT 组患者相比，3D-CRT 组患者的平均肺部剂量（分别为 4.4 Gy vs. 7.6 Gy vs. 10.9 Gy；p < 0.001）、平均心脏剂量（分别为 5.4 Gy vs. 10.0 Gy vs. 13.1 Gy；p = 0.003）和平均食管剂量（分别为 6.3 Gy vs. 9.8 Gy vs. 13.5 Gy；p = 0.011）更低。20名患者（19.8%）出现疾病复发，7名患者（6.9%）死亡。不同 RT 组的存活率差异无统计学意义。结论在接受辅助 RT 的 TET 患者中，PBT 对邻近危险器官的照射剂量较低。PBT组患者的存活率与其他组没有明显差异。
Comparison of radiotherapy techniques in patients with thymic epithelial tumor who underwent postoperative radiotherapy
lower mean lung dose (4.4 Gy vs. 7.6 Gy vs. 10.9 Gy, respectively; p < 0.001), lower mean heart dose (5.4 Gy vs. 10.0 Gy vs. 13.1 Gy, respectively; p = 0.003), and lower mean esophageal dose than patients in the 3D-CRT and IMRT groups (6.3 Gy vs. 9.8 Gy vs. 13.5 Gy, respectively; p = 0.011). Twenty patients (19.8%) showed disease recurrence, and seven patients (6.9%) died. The differences in the survival rates between RT groups were not statistically significant. Conclusion: In patients with TET who underwent adjuvant RT, PBT resulted in a lower dose of exposure to adjacent organs at risk. Survival outcomes for patients in PBT group were not significantly different from those in other groups.
