摘要导读Editorial abstract summary
这项回顾性研究纳入21只接受颅内脑膜瘤切除的犬，其中13只另接受术后放射治疗。6只发生局部复发；总体中位生存时间为845天，无进展生存时间为771天。仅手术组与加用放疗组的上述生存指标差异未达统计学显著。作者指出存在选择偏倚，因而不能确定术后放疗的获益；不能将此解读为已经证实放疗无效。
The retrospective cohort comprised 21 dogs undergoing intracranial meningioma resection; 13 also received postoperative irradiation. Six experienced local recurrence. Median overall survival was 845 days and progression-free survival was 771 days. Survival comparisons between treatment groups were not statistically significant. The authors identified selection bias as preventing a firm conclusion about the added benefit of irradiation; absence of a significant difference is not proof of ineffectiveness.
