目的 探讨原发性肝癌术中放疗的可行性和优点.方法 利用放疗计划系统对16例肝癌患者,结合靶区剂量曲线分布情况和剂量体积直方图,进行术中放疗,并与三维适形放射治疗和PBT进行比较.结果 肝癌术中放疗90%的剂量线均能包绕靶区体积,显著好于三维适形放射治疗.肝癌术中放疗治疗计划与PBT计划相似,但治疗费用明显低于PBT费用.结论肝癌术中放疗能使靶区剂量分布均匀,适形度好,同时也有效地保护了敏感器官,有望提高肿瘤靶区剂量及肿瘤局部控制率.

Objective To study the feasibility of intraoperative radiotherapy (IORT) in primary liver cancer. Methods Based on the target of dose curves, the dose-volume histogram (DVH) and cost of radiation equipment and radiation therapy, IORT was compared with protonbeam therapy (PBT) and 3DCRT in 16 patients with primary liver cancer using the therapy plan system (TPS). Results IORT had significantly better performance than 3DCRT to allow a target region surrounded by 90% of the dose lines. IORT was similar to protonbeam therapy in terms of target region surroundings and absorbed dose in the normal organs, but the cost of IORT was significantly lower. Conclusion The TPS of IORT is better than 3DCRT and similar to protonbearn therapy in the treatment of primary liver cancer with similar cost to 3DCRT. IORT can effectively protect the neighboring sensitive organs and improve the absorbed dose in the tumors and the local control rate.
