查询词典 reasons

Local recurrences mainly occurred in the nasopharyngeal cavity and the skull base bone. Dosimetric analysis showed 9 cases of in-field failure, 4 cases of marginal failure, and 2 cases of out-field failure. For the 6 cases of marginal and out-field failure, the main reasons of recurrence were low dose area in target volume due to not strictly following the guidelines of defining field limit, or inappropriately estimating the involved regions of lesions.

局部复发的主要部位为鼻咽腔、颅底骨质；局部复发灶和照射野模拟剂量学分析发现野内复发9例，边缘复发4例，野外复发2例。6例边缘和野外复发的患者，经过进一步分析发现复发与未严格遵循常规设野原则或对病灶范围判断失误造成不适当的照射野边界导致靶区出现低剂量区有关。
